Received 18 April 2008

Energy efficiency is one of the most potent and cost effective ways of meeting the demands of sustainable development. It has in fact been referred to as the best energy resource. Way back in 2005 the South African Department of Minerals and Energy (DME) published its Energy Efficiency Strategy in support of some of the objectives enlisted in the 1998 White Paper on Energy Policy. The Strategy set a national target for energy efficiency improvement of 12% by 2015 against the baseline year 2000. The document further predicted that, with a business as usual model of energy usage, at the projected rate of national economic development, there would be a need to invest in new power generating capacity by around 2007. Despite the policy foresight and seemingly enthusiastic efforts, though, the dawn of
2008 saw the country gripped in an electric power crisis, with a capacity shortfall of over 10%. This paper looks at what could have gone wrong, examines energy efficiency policies and measures in other countries and how these lessons could be adopted to the South African context.

1. Introduction and background
‘Electricity demand has not reduced by the required 10% in order to stabilise the national power grid. ESKOM has therefore instituted load shedding from the 1st of April (2008) in order to stabilise the national power grid. For more information about loading shedding schedules in your area please check in your local newspapers or visit www.eskom.co.za.’ The foregoing announcement was posted in the South African national news media, including radio and television, by the power utility ESKOM from mid March 2008. This had been preceded by weeks of passionate appeals to industry and the public, by the Minister of Minerals and
Energy as well as ESKOM, to cut down on their electricity consumption by the said amount.
Energy efficiency has become recognised as one of the most cost effective ways of meeting the demands of sustainable development. It has been aptly referred to as the best energy resource. Way back in 2005 the South African Department of
Minerals and Energy (DME) published its Energy Efficiency
Strategy [1]. This was in support of some of the objectives spelt out in the 1998 White Paper on Energy Policy [2]. The Strategy set a national target for energy efficiency1 improvement of 12% by

The performance index in this case is the primary energy consumed
(or equivalent tons of oil (toe)) per Gross Domestic Product (GDP) of growth.

According to [3] the national energy intensity of South Africa stood about 3.3 times the average in OECD countries in 2000. This is despite the fact that energy consumption per capita in South Africa is about half of the average consumption in OECD. See Table 1. Additionally the country is ranked as the 7th biggest emitter of green house gases
(GHG) per capita. So there are serious environment issues as well.
The target set out in the South African Strategy would be achieved largely via enabling instruments and interventions. They would specifically include economic and legislative means. Such measures as efficiency labels and performance standards, energy management activities and energy audits, as well as the promotion of efficient practices would be adopted.
The Strategy document further predicted that, with a business as usual model of energy usage and at the projected rate of national economic development there would be a need to invest in new power generating capacity by around 2007. In the intervening period sporadic blackouts that initially appeared to be due to maintenance were experienced in various parts of the country particularly the high-load centres of Gauteng and
Western Cape Provinces, with the frequency peaking during the winter months of June and July.
ESKOM responded with several ad hoc interventions like the roll out of millions of free compact fluorescent lights, to retrofit the traditional incandescent lights, particularly to low-income households. The utility also began advertising energy saving campaigns through its demand side management (DSM) website [5] that

included offers of financial incentives to consumers who would observe a listed catalogue of energy saving measures and tips.
Despite the policy foresight and seemingly enthusiastic efforts, though, the dawn of 2008 saw South Africa gripped in an electric power crisis, which threatened even the continuity of the very core of the country’s traditional economic engine, the mining sector. The estimated generation shortfall was 5000 MW or just over 10%. This was precisely the time that had been predicted by the strategy document. The accuracy of the timing of this prophecy is, arguably, the most compelling indictment against the country’s lack of decisiveness in the implementation of policy beyond the energy strategy.
It is now widely recognised that the most potent and costeffective energy (as well as environmental) conservation model follows a hierarchy structure of prioritization. In principle one has at the top of the hierarchy the changing of human behaviour to reduce demand while not necessarily compromising on value.
This is followed by the application of improved technologies such as energy efficient appliances. After this one considers power generation from (distributed) renewable and sustainable resources. Then follows the adoption of modern low or no carbon technologies for conventional resources and only as a last resort would one consider (at least in theory) traditional exploitation of conventional energy resources.
But, as the IET [6] has rightly observed, there is no silver bullet to the scale of energy challenges that humanity is currently facing and the only viable solution lies in a well configured mix of available ‘hard’ and ‘soft’ options. But how conducive is the South
African energy policy environment for addressing these challenges?
To begin with, since the publication of the Strategy there has been no follow-up legislation. Consequently, there is no yardstick by which progress could be monitored, since no process has been legally set in motion. Nor has there been any publication of estimates in energy efficiency trends.
This paper examines some energy efficiency policies and measures that have been used in other countries and how these lessons could be adopted to the South African context.

2. Drivers and procedures for energy efficiency other countries
Different countries drive their energy conservation agenda by adopting different socio-political strategies [7–10]. In a 2004 report the World Energy Council in collaboration with the French
Environment and Energy Management Agency (ADEME) published energy policies in 65 countries, studied and evaluated since
1992 [11]. In the EU [12–14] for example the main emphasis has been on environmental conservation while in the US, the enhancement of national energy security has been the main focus. Laws to enforce or guide these policies and strategies were as a rule, always put in place.

On December 19, 2007, President George Bush signed into law the Energy Independence and Security Act of 2007 [15]. It embodies among others, the Renewable Fuels Mandate, which will enable an increase in the use of renewable fuels of 500% and thus requiring fuel producers to achieve a capacity of 36 billion gallons in 2022. It also embodies the Vehicle Fuel Mandate, which specifies a national mandatory fuel economy standard of 35 miles/ gallon by 2020 and consequently increasing the efficiency by 40%.
The Act also advances lighting efficiency through the Lighting
Efficiency Mandate. This will see to the phasing out of incandescent bulbs by 2014 and improve the general lighting efficiency by over 70% by 2020. Added to these is the Appliance Efficiency
Mandate, which sets 45 new standards for appliances. And finally the Federal Government Operations Mandate will see to the reduction of energy consumption of Federal Government facilities of 30% by 2015 and subsequently forcing all government buildings to be carbon free by 2030.
Japan is the world leader in terms of energy consumed per unit
GDP of growth. Their basic laws concerning energy conservation and the environment have been in place for over 30 years. Act no.
49 concerning the rational use of energy came into force on the
22nd June 1979 [16]. This along with subsequent additions and revisions [17–21] saw the country achieve an unprecedented reduction of 37% in energy efficiency2 (in terms tons of equivalent oil consumption per GDP of growth) over the period.
In 2006 the Japanese cabinet approved the New National
Energy Strategy. It set an energy efficiency target of a further 30% by 2030. The stated objectives were to, establish energy security measures that the Japanese nation could trust and rely on, establish the foundation for sustainable development through the comprehensive and integrated solution of energy and environmental issues. The Strategy, however also called for expanding energy and environmental cooperation in Asia.
The Japanese spelt out a set of concrete measures that would be put in place to achieve five stated goals. First was the reduction on dependence on oil as a primary energy source to o40% through the structural change of energy demand and supply. This would be carried out by the implementation of a variety of plans and actions to achieve the other four goals. Secondly, the consumption of oil in the transport sector would be reduced to 80%, through a three pronged strategy namely, improved fuel efficiency, introduction of biomass fuels and promotion of the use of electric and fuel cell vehicles.
Third measure would be the improvement of fuel efficiency.
The fuel efficiency of passenger vehicles would be improved by
23.5% from 13.6 in 2004 to 16.8 km/l in 2015. This target would be achieved by rapid progress in engine performance and promotion of further spread of diesel engine cars. This would also include the improvement of the fuel’s octane value through research.
In the area of biomass fuels, regulations on fuel quality would be revised. Next would be the introduction of futuristic technologies of hydrogen, electric and hybrid vehicles. Appropriate step up of research and development (R&D) as well as infrastructure would support these developments. In addition to the stated technical measures the diffusion of these new technologies (into society) would also be actively encouraged. Another measure would be the promotion of energy conservation.
All these measures are categorized into four general sectors namely, industrial, civil, transport and an additional sector for cross-cutting issues. The highest achievements were realized in industrial energy conservation. This had been primarily anchored

It ought to be emphasized that the energy consumption of Japan only decreased in terms of units per GDP but actually increased in real terms since the economy grew over the said period. A similar scenario should happen over the projected period.

by two policies namely, the Guidance Policy and the Top Runner
Programme. These were the joint efforts of government and industry under the support of the general public.
The Guidance Policy was enabled through rationalization and modernization by industry or enterprise. The policy was originally based on industry voluntary participation and primarily introduced in manufacturing sector. Government would set a guideline for industry and industry would be asked to come up with an action plan. It would also provide guidance to industry where necessary. Thereafter government would make performance assessment. The Top Runner Programme, on the other hand, was enabled through development and diffusion of new products or commodities. The best facilities, plants, equipment, and instruments that were already in practical or commercial use were adopted as the standard for energy efficiency. The program was originally introduced to home appliances such as refrigerators and air conditioners. By this program a substantial number of commodities reportedly achieved 10–30% of energy saving [21].
The implementation of a well-planned energy efficiency strategy, however, may not necessarily result in a trouble free success story, due to a variety of factors. In their review of energy conservation initiatives in India, Nandi and Basu [22] enumerate a range of barriers encountered by the country’s energy conservation programmes. These included political interference as well as lack of adequate consumer sensitization and awareness. In a
Swedish case study lack of investment capital was cited as a major barrier to energy conservation [23].
There were also circumstances where seemingly well-executed energy efficiency programmes resulted in less than the expected energy savings. Examples include such phenomena as the socalled ‘rebound effect’ [24] where consumers subsequently use the savings realized in additional expenses. Quite often these additional expenses are luxuries. Even the Japanese point out that conservation measures in the household and transport sectors have not been as successful as in industry. This was largely attributed to the fact that household and transport energy usage relied more on individual human efforts and behaviour.
Despite such setbacks, however, most of these programmes realized actual positive gains even if less than might have been anticipated. In any case this author has not come across a country that managed to achieve any energy efficiency gains without a well-executed policy strategy.

3. Applying the hierarchy model to South Africa
3.1. Changing human behaviour
Talking of climate change, John Baird, the Canadian Environmental Minister has once remarked that nothing short of a total cultural change of our patterns of behaviour and activity, our habits, technology and ways of doing business and politics can achieve the massive transformation needed to avoid the worst
[25].
A 2006 study [26] was conducted by the Commission of
European Communities to solicit public views on the, ‘‘Green
Paper on Energy Efficiency, or Doing More with Less’’ [27] that had been published by the EU Commission on Energy and Transport, the previous year. The participants included, Non-government
Organizations (NGOs), Member States and public bodies, industry, the private sector and private citizens.
A number of questions were posed to the participants. For example, how investment in energy conservation could be stimulated. The most popular response was that there was need for sensitization and information. The report adds, ‘ ‘‘Green’’ ethics

1593

and behavior should be encouraged and embedded in people’s minds because the steering engine for action is society.’
In South Africa, the government and ESKOM, the power utility, have for long recognised and used the model of public sensitization and information. Unfortunately, the purpose for the effort has traditionally been to achieve the precise opposite namely, more consumption. Like all traditional utilities the primary objective has always been to maximize sales. This was augmented further with a plethora of direct and/or implicit messages that the country had the lowest electricity tariffs in the world, apparently, implying that there is plenty to go around. Not surprisingly, therefore, a section of the public found ESKOM’s recent apparent change of mind, quite confusing. The government was also hard pressed to convince South Africans that the power shortage problem was not as a result of ESKOM’s incompetence that could perhaps be solved by the replacement of the management.
Another problem would appear to be the utility’s apparent failure to solicit or encourage consumer contribution when tackling any problem. This could lead to possible lack of consumer buy-in to their proposals. For example, the aforementioned DSM website only contains instructions and ‘tips’ as to what consumers should do and no room seems to be given for any contribution from consumers. It is apparently deemed neither possible nor desirable for the consumer to make any useful suggestion. This is in sharp contrast with, for example, the aforementioned Japanese
Guidance Policy, where government (or in this case ESKOM) would set a guideline and industry (the consumer) would be given the responsibility to come up with the action plan.
The Government and utility have also not been seen to lead by example. With all their messages to urge the public to conserve energy ESKOM has made little or no effort to demonstrate that they are practicing these same measures. This includes their generation and transmission infrastructure as well as administrative facilities.
In an attempt to interrogate the efficacy of the current ESKOM
DSM drive, this author posed the following pertinent questions, by email, to the designated Industrial Sector Contact Person for
ESKOM DSM.

 Are we drawing the attention of the South African consumer?
 Are we making any in-roads in reaching the South African consumer?  Are we succeeding in convincing the consumer to act?
 If so, is the consumer’s reaction sustainable?
 Do we have an index by which to quantify our success (or lack thereof)?  Do we have an effective energy services industry through which we can sustainably reach the consumer?

 If the answers are largely, NO, how can we (the public, institutions) contribute to help?
In response by a telephone conversation the DSM caller told this author that she required conferring with her superiors before responding to the queries. Further attempts by the author to contact ESKOM on the issue were totally frustrated, by a total communication blackout.
In order to comprehend the severity of South Africa’s and in particular ESKOM’s energy information confidentiality one needs to look briefly at the country’s history. South Africa was subjected to international isolation, particularly during the 30-year period before 1994. Survival through self-sufficiency during that period became the Government’s priority. Energy was a major component of the State Security Machine. Consequently the South
African government severely restricted energy-related information and statistics through Acts of Parliament [28]. These

1594

restrictions led to the unavailability of comprehensive energy information and lack of good energy data. Unfortunately this legacy still lingers on.
In her introductory remarks in the 2005 (tri-annual) Energy
Digest the Minister of Minerals and Energy (DME), Lindiwe
Hendricks, lamented that the supply of energy data was only available on a voluntary basis even to her ministry [28]. ESKOM’s dominance of the electricity supply sector means that virtually the country’s entire database is in their custody and without their cooperation no serious planning can be effected by any other institution whether public or private. To address this anomaly the
Minister pledged that the DME would (among other measures) be making the provision of energy data mandatory through a new energy bill. The bill is yet to be publicized. Without transparency in energy supply, delivery and consumption data, it would be difficult even for a private investor to make an informed decision.
There are other seemingly trivial issues that have also been identified as disincentives to sustained consumer participation in energy efficiency drives in South Africa. One example is a practice of inconsistency (or delay) in the reading of consumer energy meters by utilities. Complaints have been raised particularly by domestic consumers who may have undertaken some measures to save energy, over certain periods, but failed to notice a reflection of this effort in the bills. Unfortunately, this frustrated anticipation is common as many South African municipalities have a practice of lapsing long periods between the time of reading the meter and billing [29–31]. In many cases the authority merely estimates
(rather than actually reading) a consumer’s monthly consumption based on previous performances and only following up for correction months later. Thus many a consumer is left wondering whether any of the measures previously taken did in fact make any difference.
Introducing energy awareness to children through schools has been suggested as one of the most effective tools in sensitizing society. In the US for example, the Department of Energy (DOE) designates the month of October as an energy awareness month
[32]. Schools are encouraged to promote this objective by participating in energy efficiency and conservation activities.
However schoolteachers have been identified as often lacking the training in issues related to energy efficiency, renewable energy sources and the rational use of energy. Additionally, traditional school curricula have been identified as often lacking the flexibility to adopt such subjects. And even in instances where trained advisors may exist in local authorities and institutions of higher learning they often have problems accessing the education sector. The severity of this problem was highlighted at the EU energy education conference EUSEW 2008 [33] where the opportunities of introducing energy education into national curricula were discussed. 3.2. Energy efficient appliances
The South African Energy Efficiency Strategy listed appliance labeling as one of the anticipated measures in the energy efficiency drive. A participant at the Motor efficiency workshop during the May 2008 Industrial and Commercial use of Energy
Conference in Cape Town [36] lamented that the South African
Government had long promised the removal of duty on highefficiency motor imports as a way to promote their market penetration but never seemed to actually implement it. The DME representative responded by stating that the failure to implement the duty waiver was due to the absence of a South African
Standard clearly spelling out the technical parameters of a highefficiency motor for the Customs Department.

In their contribution, ESKOM through the aforementioned DSM program have endeavoured to achieve similar aims. But, in the absence of an act of parliament and/or a standard technical yardstick and transparent statistics it is not clear what impact has been achieved on the ground. Moreover instead of specifying performance criteria, ESKOM and the DME have prescribed a list of activities or technologies that must be employed by consumers to qualify for the incentives. This lack of a clear performance criterion means that consumers or energy service companies that use technologies that are not on ESKOM’s ‘approved list’ cannot claim the compensation promised, even when they can demonstrate that savings were actually been realized. The following case makes an illustration.
A local South African company has been marketing loadcompensating technology for several years. Many industrial and commercial electric loads draw unbalanced and reactive currents.
This results in the demand for reactive power and negative sequence currents from the grid but which do not result in useful work. The generation and transmission of these currents thus results in unnecessary losses and compromises the overall efficiency of the grid system. But this problem can be mitigated by installation of suitably specified and configured reactive components (like capacitors and inductors) at the consumer end. The equipment automatically monitors the state of the consumer load and takes corrective action. This is load compensation. The process does not require any real power generation and therefore cuts produces no GHG but is very effective. It is also a mature and reliable technology. The technology has however not been in use in South Africa.
Consequently an investor has identified this technical gap and has already established a client base. However at the 2007
Commercial and industrial Use of Energy Conference in Cape
Town the investor lamented that ESKOM had declined to pay them the money promised as DSM incentive because the technique was not on their (ESKOM) check list. This was despite having proved that the consumers had drastically reduced their monthly electricity bills. This author subsequently inquired with ESKOM as to why this was so and ESKOM only promised to look into the issue. This author however believes that rather than insisting on prescribing specific technologies the utility and the government should focus more on setting performance standards as the criterion for rewarding energy efficiency. This way they would vest the responsibility of compliance with the consumers who must ultimately regulate their behaviour and optimize energy usage regardless of the technology employed.

3.3. Deployment of distributed and renewable resources
Distributed resources have been shown to be very effective in promoting energy efficiency by, among other attributes, mitigating power delivery losses. This particularly so as such losses are proportional to the square of the transmitted load. Therefore, seemingly small changes result in large savings. Their smaller sizes also mean that they carry lower financial risks and shorter lead times to install. In their best seller ‘‘Small is profitable,’’
Lovins et al. [34] explain, through numerous examples, that even from a purely economics point of view, ‘‘Today’s electricity industry-large power stations feeding a nationwide grid-will have to change.’’ And what will replace them? ‘‘Decentralized and distributed electrical resources, which can have up to ten times the economic benefits,’’ they emphatically proclaim.
Currently, the most popular distributed generation mode in
South Africa is the use of gas turbines mainly as peaking power generators. This has obvious long-term sustainability issues, not

least, of which is their dependence on the importation of fuels that are subject to international markets volatility. Renewable energy generation would offer the prime candidate technologies to address this problem due to the abundance of sunshine and wind in the country. Japan and Germany are world leaders particularly in household grid-connected photovoltaic generation and have demonstrated the viability of these technologies as well as the impact that an individual household can make.
Another distributed resource technology that has been identified as having great potential in energy conservation in South
Africa is co-generation. This would particularly exploit the waste energy at the country’s energy intensive industries such as smelters and is estimated to be between 1000–3500 MW [35]. It was however revealed at the May 2008 International Conference on Industrial Use of Energy in Cape Town [36–38] that potential investors are still hampered by lack of a legislative framework due to a pending energy bill. As an ad hoc measure ESKOM has organized a small pilot project in which interested investors have been invited to submit their proposals [38]. But the selection will be severely limited in numbers.
3.4. Adoption of low carbon technologies
In principle low-carbon coal generation has been floated as an option in South Africa’s future energy mix. However, it is also known that using current technologies the cost of containing carbon dioxide from a coal powered generator is nearly equal to all the other costs [39–42]. This effectively results in doubling the cost of every kWh generated. When combined with the long leadtimes involved to get a plant online makes the option extremely unattractive and diminishes its prospect of emerging as a serious future option for South Africa.
Another option that the country seems to be pegging their hopes of limiting CO2 emissions is nuclear energy. South Africa has traditionally operated a 2000 MW nuclear power station located at Kuberg in Cape Town. This is largely a French design. It has in recent years been in and out of commission due to a variety of faults. As an extension of their peaceful nuclear program the country is currently involved with international partners to develop a next generation technology of nuclear generators, particularly the Pebble Bed Modular Reactor (PBMR). The original aim was to have online 25,000 MW of nuclear generation by 2025.
The program has however been hampered by slow development.
Originally slated for demonstration by 2011 the program has subsequently been postponed, several times with no definitive date on offer.
3.5. Traditional coal generation
South Africa is endowed with vast coal resources. This has traditionally provided the country with a cheap and secure supply of feedstock for almost its entire electric power generation and manufacture of automotive synthetic fuels and the principal culprit for the country’s heavy carbon footprint. The prospect of coal shortage would therefore be the last reason that South
Africans would imagine as a possible cause for power shortage. It would however appear that the bulk of the extract has in recent times found its way into the lucrative international fuel markets, particularly China and Japan [43,44]. And this has apparently come at the expense of local consumption and pricing.
The extent of this problem became more apparent in the aftermath of the early 2008 power crisis when shortage of coal feedstock was cited among the reasons for the problem. In fact the
Minister for Mineral and Energy was reported to have threatened to use emergency powers to requisition any stocks destined for

1595

export to arrest the domestic crisis. ESKOM subsequently paid for a series of radio and TV campaigns to reassure the public that it was taking measures to top up its feedstocks. But it would appear that ESKOM will no longer be able to enjoy the traditional low prices. Future feed stocks will have to be obtained at the same spot prices determined by the escalating international demand for fuels [44].

4. Concluding remarks
A range of options available to South Africa for a successful energy efficiency and conservation drive has been explored. Many of these options have been tried successfully elsewhere.
From the plethora of government policy and strategy documents [1–5,45,46] it is quite apparent that (at least in principle) the government is aware of and recognises the efficacy of most of these options and would appear intent on undertaking them.
It is, however, in walking the talk that the government would appear to falter. Their failure to, timely, enact and implement the necessary legislative mechanisms to set these policy objectives and strategies in motion, is a major omission. It may be true that the enactment of legal instruments alone may not necessarily eliminate all the barriers. This author has however not come across any precedent where such a process succeeded through ad hoc measures, unsupported by legislation, as seems to be happening in South Africa. And as has been observed, legislation does set out clear targets, timelines and identifies the means by which to achieve them.
For public sensitization and awareness the utility and the
South African Government should endeavour to be seen to practice what they ask society to do. Even a symbolic demonstration through promotion of energy efficiency in government buildings could go a long way.
Additionally, what would appear to be conspicuously absent from all these documents, are the targets for human capacity development. While in the case of Japan and the US one could assume that such capacity may perhaps be sourced from the available large skills pools from the public and private sectors, the same cannot be said of South Africa. In fact there is currently a big shortfall in technical skills for a whole range of existing disciplines
[47]. It would therefore be prudent that targets for human power development as well as the appropriate timelines are included.
The adoption of energy-related courses in school curricula would greatly augment these efforts.
It has further been observed from the highlighted international cases that the industry sector and general public should be actively involved in the formulation of energy conservation policies, strategies and action plans. This model is important particularly for that all-important consumer buy-in and exploits a wider pool of the country’s creative resources. The Japanese success, particularly in industry, would appear to have been largely anchored by their masterly of this model.
By contrast however, complaints abound among a number of
South African stakeholders that have participated in past government hosted consultative workshops and policy document reviews (including this author) that their inputs never seem to filter through to the final documents. The aforementioned format of the
ESKOM DSM website, where the host provides all the energy conservation ‘tips’, is just but an example. The Secretary General of the Congress of South African Trade Unions (COSATU),
Zwelinzima Vavi, recently scoffed at ESKOM’s invoking of a confidentiality close as justification for refusal to fully disclose reasons why they were requesting the National Energy Regulator
(NERSA) for a whopping 53% tariff hike. And as Gordon H.G. et al.
[48] have observed, if consumer energy conservation policy is to

succeed, both behavioural and institutional obstacles must be identified and overcome.
Otherwise, this effectively one-way information channel makes it very difficult for the government to achieve appropriate social adoption, acceptance and subsequent take up of sustainable conservation measures by society. It cannot be overemphasized that the steering engine for action is society.

Memory

...Memory Summary There are three stages of memory. Encoding, storage, and retrieval. Encoding can be done in three ways: visual, sound, and the meaning of something. It refers to the process of transforming information into a form that can be entered and retained by the memory system. Encoding allows information that is from the outside world to reach our senses in the forms of chemical and physical stimuli. For example, to memorize the definition of a key term that appears on a textbook page, you would visually encode the patterns of lines and dots on the page as meaningful words that could be retained by your memory. Storage has to deal with how long information is retained, where it’s stored and how much can be retained. It’s the process of retaining information in memory so that it can be used at a later time. Retrieval involves recovering the stored information so that we are consciously aware of it. Although, some retrieval attempts may be effortless due to the type of information being retained. It’s getting the information out. It also has to deal with STM and LTM. STM is stored and retrieved sequentially. LTM is stored and retrieved by association. Understanding how your memory works can help you learn by knowing which type of learning makes the things you have learned stick in your mind. Once you know this you can continue learning the way you feel helps you remember it. Psychologist have come up with thirteen steps in order to enhance your memory to retain more information...

Memory

...The Power of Memory It never seizes to amaze me how different colors, tastes, smells, and sounds can take us back to an event in our lives long forgotten. Its astounding how we can recall events with such clarity, though sometimes our memories are tainted with the hue of the dominant emotion we may have felt at the time. We look at our present through the memories of our past experiences. Scanning through different stations on the radio, it seems like all the stations are playing the same songs. A particular tune catches my attention and I wait to hear the lyrics. Its Barbara Striesand singing one of her hits from the seventies, the song’s title is ‘memories’. Speaking of which, my mind drifts off to the time when I was four years old and unable to sleep at night, I had sneaked out of my room to see whether anyone was up, to find my parents sitting with dimmed lights, listening to this same song. I remember thinking then that they were being romantic, and I was not supposed to be there. Feeling left out; I quickly started to complain of a fake stomachache and how I needed someone to read me a story to be able to sleep. It was a fruitless endeavor, I was sent to bed - no story - just a lecture on how all the good children must be asleep and I was still up. I relate the story to my brother, who is complaining about why I’m listening to such ancient music and should put his ‘hip hop’ station on. He changes the station. My thoughts are rudely interrupted by...

Memory

...Memory is an important cognitive process, which helps us to record the past so that we can refer to it later, as and when required. Without memory, there would be no past, but only the present. We would not be able to execute all the psychological processes that depend on our past experiences. We would be perpetual beginners for every activity that we perform everyday. If we do not retain information over time, and retrieve it for present use, we would not be able to recall names, recognize faces, and understand the concept of time. Even the present would not be our own, because there would be no concept of self-identity. An individual would wake up every morning, and doubt that he is, and would have to rediscover his identity every day, every hour, every second, and even every millisecond. The identity of the individual would be lost, and the whole world including himself would appear to him as a booming buzzing confusion. The feeling of personal identity is based on a continuous stream of memories that link our yesterdays to today. Since memory is an important cognitive phenomenon, psychologists have devoted considerable time and effort to understand the process of memory, and the strategies to improve memory. Memory is the retention of information over time. It has to be retrieved from its store for present use. Psychologists and philosophers have opined differently at different times on the concept of memory. But the contemporary cognitive psychologists are of the...

...Creating False Memories Fall 2011 Creating False Memories This experiment was unique and presented insight into creating false memories by using influence of suggestion. There has been various articles and research done on memories and whether or not a person’s memories can be considered credible. It is thought that memories can be altered by a person’s past events. As I seen from this experiment, memories can be altered just by simple suggestion. I practiced this experiment on my wife and seven children. Every person circled the word “snow” no matter what list they studied from. I considered the possibility that their thoughts were about the weather due to the rain and cold temperatures from that day. I decided to wait a few days before trying the experiment on the actual volunteers, eager for improved weather conditions. Our local church was having a meeting with many of its members. I waited for the meeting to finish and asked if four people would be willing to volunteer to participate in a research project. I asked the four volunteers to have a seat and patiently to do this experiment one person at a time. I brought the first volunteer into a separate room and explained the consent form and informed them that this was a simple memory test and there would be no harm to them, however there may be some slight deception. I also expressed their answers and identity will remain confident. The volunteers were informed the experiment would only take about five minutes...

Memory

...Memory is a constructive process through which humans organize and shape information received constantly (Huffman, 2010). This process is divided on two major approaches called information-processing model and the traditional three-stage memory model. In this paper, I will talk about three basic operations that are part of the information-processing model. These basic operations are known as encoding, storage and retrieval. The encoding operation is responsible for processing the information received into the memory system (Huffman, 2010). For instance, when a new word is learned, the encoding operation carries it over to the memory system for the next step. The storage operation is then responsible for preserving information over time. The word learned is then kept in our memory system to be used later on thanks to the storage operation. And the retrieval operation recovers all information needed from the memory storage. For example, the word learned now has to be used; the retrieval operation goes and finds it in the memory system for us to apply. One concept that I commonly use to improve my memory is making notes of tasks or information that I need to learn or remember. Making this notes not only makes my information easily remembered, it is also being stored in my brain while I am writing it. There are many useful techniques out there to better help improve our memory. Cuesta College provides students a list of memory tips on their website that will help them...

Memory

...RUNNING HEAD: SOURCE MEMORY AND THE IMPLICATION OF THE PAST, PRESENT AND FUTURE Memory has a multitude of facets that comprise what a memory is and how a memory is characterized. Some memories are recollections, hazy moving pictures; some are unconscious working memories, while others are a bit more in depth. A source memory is a type of memory in which we remember who, what, where, when and how of a specific event. It is what gives our memories relative meaning to both time and the significance of the events that occurred in our life. A memory is generally meaningful regardless, but when we can recollect the sources of that memory, it fine tunes the events surrounding it as well as future recollections. The ability to source our memories comes full circle within our lifetime, developing in early adolescence throughout early and late adulthood, and eventually the ability becomes more tasking for our cortex within old age. Time is one of life’s few constants, a never ending stream of information in this space-time continuum. The ability of our mind to capture moments of this past in an almost capsule like photograph is astounding, being able to source these times shows how powerful memory is and the capture of moments in this never-ending continuum. Myriads of studies on source memory have been conducted and more recently within the past few decades. The studies herein focus on various source memory tasks throughout age groups, examining the differences...

Memory

...MEMORY Memory is one of the most important concepts in learning; if things are not remembered, no learning can take place. Futhermore, memory has served as a battleground for opposing theories and paradigms of learning (e.g., Adams, 1967; Ashcraft, 1989; Bartlett, 1932; Klatzky, 1980; Loftus & Loftus, 1976; Tulving & Donaldson, 1972). Some of the major issues include recall versus recognition, the nature of forgetting (i.e., interference versus decay), the structure of memory, and intentional versus incidental learning. According to the early behaviorist theories (e.g., Thorndike, Guthrie, Hull), remembering was a function of S-R pairings which acquired strength due to contiguity or reinforcement. Stimulus sampling theory explained many memory phenomenon on the basis of statistical outcomes. On the other hand, cognitive theories (e.g., Tolman) insisted that meaning (i.e., semantic factors) played an important role in remembering. In particular, Miller suggested that information was organized into "chunks" according to some commonality. The idea that memory is always an active reconstruction of existing knowledge was championed by Bruner and is found in the theories of Ausubel and Schank. Some theories of memory have concerned themselves with the nature of the processing. Paivio suggests a dual coding scheme for verbal and visual information. Craik & Lockhart proposed that information can be processed to different levels of understanding. Rumelhart & Norman describe three...

Recovered Memories

...Following the recent sensation of using therapy to recover memories from one’s past, there is increasing concern over whether or not these “recovered” memories are indeed genuine. While certain memory recovering procedures appear to be designed to help a patient relax and serve to draw out old memories, often times, patients can be so eager to recover some memory from their past that they in fact create a false illusion in their head of an event in order to help better explain an unknown part of their past. Just because an event described appears and sounds genuine, does not mean that the event has actually occurred. While the patient can be the cause for creating a false memory so too can the therapist. Suggestive influences are likely to enhance the plausibility of a memory in the mind of a patient. It is easy to be lead to a conclusion by someone who you’re trusting to help you find answers. Suggestive procedures play a role in outcomes for other experiments and it is no different when conducting experiments about false memories. Persuasive information from the media can also play a role in the minds of people, as they all believe that if they’re hearing or reading about recovered memories on the television or radio than it is possible they might have some as well. Another concern about the validity of recovered memories is the potential of false testimony from patients, as they may not want to share what actually happened. This would likely stem from some sort of traumatic...

Explicit Memory Vs Implicit Memory

...Implicit memory also referred to as unconscious memory refers to the unintentional retrieval of information that got obtained during a certain learning episode on tests that do not need conscious recollection of the previous learning episode (Garrett, 1975). Explicit memory, on the other hand, is the memory performance in which it can retrieve a previous learning episode consciously. Implicit memory requires very little effort to recall, whereas explicit memory requires significant and more concentrated effort to bring memories to the surface. Systematic investigation of implicit memory is a representation of the relatively new research direction in cognitive psychology as well as neuropsychology.

Gender and Memory

...Elizabeth Burke October 8, 2013 Gender Affecting Memory A great debate in psychology is whether gender affects memory. There has been a lot of controversy and research conducted to explain the question, does gender affect memory? After properly reviewing articles about this topic, I have concluded gender doesn’t affect memory but whether how memory is processed. Each gender has their own advantage when it comes to memory. Memory is processed differently between males and females. Women have better long term- episodic memory, while men have better long- term semantic memory. Due to verbal clues, women are more likely to remember events that are associated with emotions. These include weddings, birthday parties, or anniversaries. Due to visual clues, men are more likely to remember functions associated with tactics. These include traveling, trivia, and direction. For example, a man is more likely to able to find his way out of a forest than a woman. The size of the male and female brain differs. In a scan of the female brain, it was proven the limbic cortices, which regulates emotion, was larger. The limbic cortex also processes language. Women have neurons that are tightly packed. This allows faster communications to be made. The connections they make are more complex and sophisticated. This could explain why woman are better at multi- tasking. The scan showed the female brain has larger corpus callosum, which is bundle of nerves that ...

Memory Failure

...Memory Failure Memory Failure Memory failure is a main focus of extensive psychological research, after memory construction was delineated into three stages; encoding, storage, and retrieval, the origin of thought behind memory failure was solely on the breakdown of the first two stages, encoding and storage, until shifting its focus at the hands of Endel Tulving, who discovered the actual primary cause was due to a disruption in the third stage, thus termed retrieval failure. Retrieval failure is simply defined as the inability to access information, and the reason behind the ‘tip of the tongue’ phenomenon. My Failed Memory As I walked with my patient into my first school meeting to test my ability as a community liaison, I felt confident. Not only did I wake up early enough to study her chart, background, and write down her effective coping mechanisms; I brewed a fresh cup of coffee, reminiscent of the one I drink each day and night, and arrived on-site just in time to see her arrive. As I sipped my coffee, watched her mothers van park, mouthed the words to a song on my playlist while checking my timing, I felt on top of all my tasks – surely going to impress. Shortly there after, unbeknownst to me, getting my patient out of the van and into the school was much more challenging then I planned for. Employing my verbal de-escalation skills, and helping communication tactics for Mom and daughter, I successfully aided her out of the van and onto school grounds. Leaving my...

Memory and Memory Recall

...| MEMORY AND MEMORY RECALL | | | | 5/17/2012 | Abstract Recalling items from memory is not always an easy thing to do. Many times people will fail to write down a phone number or a shopping item because they are sure they will remember. Too often when needing to make that call the number cannot be recalled or they return home from the store and then realize they forgot the item they initially went to the store for in the first place. It has happened to us all. This paper will look at memory, reasons for memory loss, and offer ways to help consolidate and retrieve the information we receive. | Computers and humans both have memory that work in similar ways. Both require information to be input, stored, and retrieved. Computers use Rapid Access Memory, or RAM and Read Only Memory, or ROM. In 1968 Richard Arkinson and Richard Shiffrin developed the stage model of memory. This model has three different memory systems; sensory memory, short term memory, and long term memory [ (Editorial Board, 2011) ]. Sensory memory is a very brief memory of something sensed through one of our five senses that if not passed on to short term memory and is forgotten quite quickly. Short term memory lasts a bit longer than sensory memory but doesn’t have the capacity of sensory memory [ (Course Materials, n.d.) ]. Finally, long term memory is the memory that last longer than sensory memory and short term memory. Episodic memory and semantic memory are two types of...

Memory

...Whats memory? Memory is the process by which we encode, store, and retrieve information.(APA) Memory has been around for as long as the Earth started maybe even longer. Back in the day we didn't have maps or clocks. They used the sun to tell what time it was, they also used the sun to remember where North, East, South, and West is. Back then they had to remember where they were by land marks. Encoding is the stage in remembering something, storage is saved in memory, and retrieval is the information stored is located and brought to awareness. There are 3 approaches to memory; sensory memory, short-term memory, and long-term memory. Sensory memory is the initial momentary storage of information, lasting only an instant. (APA) My example for sensory memory is when I watch the TV show, House. When they use a really big medical term it goes away right away and I forget what they said. Short-term memory is memory that holds information for 15 to 25 seconds. An example for short-term memory for me is when I think of something to write for a paper, then when I get to write it down I forget what I was going to write. Long-term memory stores information on a relatively permanent basis although it may be difficult to retrieve. (APA) For my long-term memory example, when I was in 8th grade I had to take a world map test. When it came to remembering where Norway, Sweden, and Finland it wasn't easy because they’re roughly the same size and right next to each other. The way my class and...

...Learning and Memory Humans are continually learning, storing and coding raw information that is sent to us from our sensory registers from the outside world. Because of such an overload of stimuli thrown at us, it is vital and necessary to learn as infants and throughout our lives how to store and process this information. We learn to pay attention to some material, while other data is filtered out immediately. Researchers have spent enormous amounts of time studying the different types of memory: short-term memory, long-term memory, procedural memory and declarative memory. Because the only way we survive, evolve and learn new skills and talents is by developing our minds and adapting to the ever changing demands of life. What scientists have discovered is that learning requires attention, coding and storing of past memories and experiences. In order to live healthy and happy lives, we can stimulate and encourage learning throughout our entire lifetime from infancy to late adulthood providing that our brain is biologically healthy and intact. Most important, scientists are now studying what simple changes can be made to stave off such diseases such as Dementia and Alzheimer’s. The only kind of memory that the world has ever been able to agree on is that one which saves occurrences from the past. Even more limiting is a methodical notion in which the procedure that creates memory (learning) is identified by the modification of the actions of an individual who...

Learning and Memory

...Learning and memory are both processes controlled by the brain (Okano et al, 2000). The brain is the source of the ability to learn and memorize, think, feel, want, perceive curiosity, and behavior and without memory we are capable of nothing but simple reflexes and stereotyped behaviors (Okano et al, 2000). In examining the relationship between learning and memory from a functional perspective, researchers often discuss the reasons learning and memory are symbiotic, and in doing so, have engaged in countless case studies in an effort to understand the learning-to-memory-link. However, to comprehend the functional relationship between learning and memory we must first define learning and memory. Learning is described as the acquisition of knowledge or skills through experience, practice, or study, or by being taught while memory is defined as the expression of what is acquired (Byrne, 2014). Learning and memory can be distinguished by the speed with which they happen. If a new ability or information is attained gradually and arduously, this is learning. If attainment occurs instantly, that is making a memory (Learning and Memory). In relation to the case study, The Woman Impervious to Pain and the disorder associated with her, her learning from life events and other influences including culture, environment, biological state, mental abilities, and societal advancement might have played a significant role in supporting her disorder. This knowledge might have affected...
