Quiz. Forms of memory, Ogden and Corkin paper.
1. Episodic and semantic memory make up what form of memory?

Episodic and semantic memories are sub types of declarative memory, which is also known as the explicit memory. These memories can be consciously recalled. 2. What brain structures support these 2 forms of memory?

Both semantic and episodic memory depend on the temporal lobe. Episodic memory mainly depends on the Hippocampus, whereas the overlying cortices of the hippocampus, the entorhinal and peri-rhinal cortices, have more influence over the semantic memory. Another structure known to support semantic memories is the basal ganglia.

3. What brain structure(s) support procedural memory?

The basal ganglia support procedural memory by communicating information from the sensory systems to the motor cortex via thalamus. Pre-motor area and the cerebellum are also significant to supporting procedural memory.

had to rotate certain letters (R, F, or L) mentally and decide whether the letter presented through a computer screen was mirror-reversed, or not. As a part of this task, he had to choose between two buttons labeled either “normal” or “reversed”. H.M. was able to practice this task for two days, and was tested at different timepoints. Two-three weeks after the initial testing, his results indicated that he significantly improved on the task; his reaction time for all three letters were at their shortest time, and he made fewer errors. His results in this task demonstrated that his implicit memory was still intact. However, he failed to remember what the computer was, and its function. Furthermore, he claimed not to know how to perform the task several times, but was able to perform it when presented with

Episodic Memory

...Episodic memory is a form of long-term memory that refers to facts, data, personal experiences, or specific events that are tied to particular times and places and can be recalled at will. This form of memory is thought to be connected to self-awareness in an animal. The most important feature in this form of memory is the ability to recall past events or experiences after the incident had occurred. This is a form of memory that is well known and explored in humans, but its existence in non-human animals is heavily argued over. Due to the difficulties that come with designing an experiment to test this self-awareness in non-human animals it is often called episodic-like memory rather than episodic memory. This recall ability can be assessed by using an unexpected recall test in which the event being tested is encoded incidentally, the creation of a memory without purposely knowing that memorization is...

Episodic Memory in Animals - Mental Time Travel

...Episodic memory in animals, Are they capable of mental time travel? Sarah-Jane Fahed American University Of Beirut Mental Time Travel in animals Episodic memory is a type of declarative memory, it’s the memory for personal events and is distinguished from semantic memory: memory for facts. What characterizes episodic memory is that it involves mental time travel also termed “Chronesthesia”: it is the capacity to mentally project oneself in the past to remember events that took place and projecting oneself to try and predict the future. It is commonly thought to be specific to humans but some studies have been done to research this specific type of memory and see if it can be attributed to animals. The study of episodic memory in non-humans led to many contradictory results and depends on how it is defined. The main focus of this paper is to study the different researches done on the Chronesthesia component of episodic memory in animals: mental time travel to the past and to the future and show their limitations. Tulving originally defined episodic memory in terms of the kind of information it appears to store: what where and when something happened (the www criterion) and later added the concept of autoneotic awareness to the definition (as cited in Suddendorf & Corballisb, 2007): the sensation that a memory was personally experienced In their book Missing Link in Cognition: Origins of Self-Reflective Consciousness Terrace...

Stress

...this video, I will tell you something about one of our biggest enemies. We all hate it, we don’t want it, but it still exists, still appears beside us whether we like it or not. So, can you guess it? It’s stress. Now I know maybe some of you are laughing at me and thinking in mind that: oh, I know it clearly, I face it every day and what else do suppose me not to know? Something like that, right? Okay, but guarantee you, I just found out some other new good aspects of stress, u would like it. So just wait and see. Many people experience stress as they combine busy lives and the demands of study and or work while trying to also save time for friends and family. For some people, stress becomes almost a way of life. We all experience episodic stress – getting ready for a major exam, completing an important paper, perhaps getting ready for an important interview. However, a continuous “state” of stress should not become a way of life. We know that stress – over a prolonged period of time – can have increase certain health risks, to say nothing of the wear and tear that happens to relationships and general wellbeing. In today’s society, every day we may face some kind of stress and difficulties from work, school and family. Work-related stress has many causes, including long hours, heavy workload, job insecurity, the threat of job loss or redundancy, and conflicts with other workers or even your boss. If you are students, may be something like: oh, I can’t get it...

According to Sternberg, what is Kara’s IQ? Conduct research and interpret her score. Choose two theories of intelligence. Write a 150- to 200-word discussion on the components of each theory, and how they differ in relation to Spearman’s g factor. According to Sternberg, Kara’s IQ is 90 because at ages 10,11,12,13 the level of IQ is more than ages above 17 because of initiation to adulthood. Kara’s scores will be high because children with elevated levels of intelligence are more likely to learn in the school setting comparatively to their peers with lower scores. This gives evidence to the relationship between IQ scores and school performance. The triarchic theory of intelligence was created by Sternberg while he was piloting research on human intelligence. The triarchic theory is made up of three components. The first component addresses the relationship between intelligence and experience...

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

...Unit 4 Ip Debrenia Massey AIU Online Abstract The functions of a human brain consist of memory in the way things are thought of and learned and in the process. In the paper I will Identify and describe as well as give examples of how the human brain memory works. Also in this paper I will explain other kinds of forgetting and discuss the strategies that can improve memory consolidation and retrieval. Memory, Thinking and Intelligence The human memory consists of three processes: encoding, storage, retrieval. The encoding is the first process in the human memory and it is where information is transformed to be stored into a memory. The storage is the second process in the human memory and it is where physiological change has to take place in order for the memory to be stored. And the last process in the human memory is the retrieval process which is where you can retrieve memories that you stored originally during the encoding process so that the information stored can return to the same point it was in the beginning. In 1968, Richard Atkins and Richard Schifrin developed the Stage Model of Memory; which describes the basic structure and function of memory (Introduction to Psychology, p. 123). This model is made of three memory systems: Sensory Memory, Short-Term Memory, and Long-Term Memory.  The Sensory Memory is the beginning stage of the memory process. It uses the five memory sense touch, smell, taste, sound, and sight. These sense organs have a limited ability to...

Journey of the Magi

...Has God ever given me a mental image to figure out a piece of my life’s puzzle? Thinking deeper on the subject I can only wonder how many times this has actually happened and I didn’t realize it was God’s way of helping me get through something. Further reading on the retrieval of autobiographical memories I realized that this form of episodic memory pieced my life puzzle together better. I have always been able to remember special events in life with ease. I can at least pinpoint the time of year and what surrounded me during the event. I have always been able to do this. I continuously replay my life’s events in my head from as early as I can remember. It is possible reading from the text that I do this do dwell more on positive aspects of my life. I did in fact have a rough life and can see now why I would want to replay happier memories in my head and remember them forever. Prof Donovan stated near the end of her video “just wait for God’s timing and he will tell you where it goes”. She was talking about that puzzle piece that gets us through a difficult situation. Having an autobiographical memory is a true gift from God helped me get through losing my mother last year. I didn’t realize what he was preparing me for in the future but the simple task of replaying events in my head helped a lot. I was able to remember some great things about my mother and was able to make sure her true wishes were met. It helped me honor her for the great woman she was in life. I know...

Memory: Carl vs Hoerl

...sense of time, Hoerl claims that people who lack an episodic memory cannot grasp a sense of time in a way that more “normal” individuals can. Craver, accepts that amnesiac individuals may lack an episodic memory, but sets out to systematically refute the notion of this type of memory as a requirement for being an agent. I believe that the definition for episodic memory is far less constraining than either of these two philosophers are willing to give. I suggest that on an individual level, time and memory are interdependent and only if memory is completely nonexistent, will a person be relieved of their identification as an agent. Given this, Craver’s defense of amnesiac persons hold true, and further, these people indeed do hold a sense of time. Craver takes several angles from which to refute the absence of agency in amnesiacs. First Craver takes Locke’s diachronic view of identity and discusses the requirements for what constitutes a memory. These are: a) The person has an apparent memory of an experience, b) The content of the apparent memory is identical (or very similar) to the past experience c) The person in fact had that experience. Craver uses a follow-up system in which C is altered to allow for the memories to be based on the emotion elicited from a past event to count as quasi-memories, however, I believe that memory does not need to be based even so far as this to count as an example of diachronic memory. Take for instance the case of Holly Ramona, a girl...

The Effects of Emotion, Imagery and Negative Feelings on Memory Retrieval

...The Effects of Emotion, Imagery and Negative Feelings on Memory Retrieval My Memory Here I was, at the 2013 U.S. Synchronized Figure Skating Championships, standing in the well-known “kiss and cry” area with my team. We just skated our second program of the competition, the long program, and it felt absolutely incredible. I remember completing each element and taking a deep breath of relief each time knowing we made it through another section of our program without a fall. Our team’s goal this season was a pewter medal, 4th place, and we were moments away from achieving it. The short program, which we skated the night before, was also incredible and it gave us close to a four point lead ahead of the team behind us. All we needed to do was get our scores and celebrate. I remember the image of the stands where our organization’s younger team and our parents stood, cheering and going crazy and waiting for our scores as well. Brooke and Alexis had those silly Shamu whale costumes on in honor of our music to a song from one of the SeaWorld shows. They started doing that silly Shamu hand signal and the rest of our cheering section did it too. I held the hands of two of my teammates, one of them my sister, tighter than I’ve held anything in my life. We stood there, anxious, staring at the screen hanging above the crowd, waiting and waiting for the announcer to come on and our scores to appear. They showed recaps of some of our best moves we performed just a few minutes ago and...

The Function of Our Memory

...Cover Sheet Title: The Process of Memory Reginald Singleton Student ID: 21978330 February 13, 2015 Essentials of Psychology SSC130 Essay 25072400 You’re at a large gathering where family, friends, and people you are not familiar with are present. Some of the people there you’ve met once or twice before, and as you engage in conversation with them they use your name several times. You on the other hand, can’t recall any of their names, and this causes you much embarrassment. Later you ask yourself, ‘why couldn’t I remember their names, it was less than 6 months ago when we all spent time together playing volleyball?’ The answer to that question might best be found by considering the process by which we encode, amass, and recover information. Based on the three-system approach to memory (Atkinson & Shiffrin, 1968) as information passes through or enters the sensory stage, which is the first step, and repetition is not carried out, this information, such as a person’s name can be lost within a second or so. Therefore, when I relate an example of my personal experience of how I forgot the name of those who I had played a game of volleyball with, I could have helped my chances of remembering by perhaps using their names frequently as we played together. Doing so would have lead to the second stage where information moves into short-term memory. In this stage, information can be stored for about 15 to 25 seconds before forgetting. I could have increased...
