Thought Experiment: A Brain in a Vat
Hypothesis:

The brain in vat is a great example to exam our perspectives to the world around. Can people live in a simulated world with only electric impulses to brains? Or people will finally find that their brains are in vats? This experiment will show that the brains will figure out the world is not realistic.

Experiment Set Up:

First we should be clear to the basic assumption of this experiment. According to the video, each of us is like a box with five holes to input. These five holes are the five senses: sight, audition, smell, taste, and touch. We use these five senses to search, feel, and understand the world. Every perspective to the world is from the five senses. For example, we know a ball is round because we see its shape; we can distinguish the sound of violin from that of piano because our audition tell us they are different; we know fire is hot and ice is cold because we have that feelings when we touch them. How these feelings turn to our experience? All of those feelings will generate electric impulses which will be sent to the brain’ neurons, so the brain will record them. This is the way we feel the world. Based on the model, if we take a brain out of a person, and connect its neurons by wires to a supercomputer which can send the same electric impulses as the normal brain received, can this brain just experiences the same as before? Secondly we need to understand how the supercomputer simulates a world. The assumption is that the supercomputer is programmed by the mad scientist, so that it can generate appropriate impulses. For instance, the brain will still feel hot when the consciousness of the person touches fire in the simulated world; the person can still enjoyed concert in the world; or the person just tastes the pasta the same as in the real world. Everything seems to be perfect: the

You will explore how you apply different aspects of science in your daily life in a two part project. In 1,500-words (minimum), discuss the following: PART I: SCIENTIFIC METHOD Each and every day, we are faced with having to make split-second decisions, and the need to solve random problems that we encounter. To reach those decisions and work those problems out you are subconsciously using the scientific method. Apply the five steps of the Scientific Method to two situations that could occur in your everyday life. Use the scientific method in the first scenario provided below to solve the problem at hand. Please come up with a second detailed scenario on your own and follow the same steps in the scientific method to find a resolution. Scenario 1: You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what? Scenario 2: Develop your own detailed problem/observation and apply the scientific method to solve.

Stress

...DIFFUSION OF RESPONSIBILITY3 JOHN M. BARLEY BIBB LATANfi New York University Columbia University Ss overheard an epileptic seizure. They believed either that they alone heard the emergency, or that 1 or 4 unseen others were also present. As predicted the presence of other bystanders reduced the individual's feelings of personal responsibility and lowered his speed of reporting (p < .01). In groups of size 3, males reported no faster than females, and females reported no slower when the 1 other bystander was a male rather than a female. In general, personality and background measures were not predictive of helping. Bystander inaction in real-life emergencies is often explained by "apathy," "alienation," and "anomie." This experiment suggests that the explanation may lie more in the bystander's response to other observers than in his indifference to the victim. Several years ago, a young woman was stabbed to death in the middle of a street in a residential section of New York City. Although such murders are not entirely routine, the incident received little public attention until several weeks later when the New York Times disclosed another side to the case: at least 38 witnesses had observed the attack— and none had even attempted to intervene. Although the attacker took more than half an hour to kill Kitty Genovese, not one of the 38 people who watched from the safety of their own apartments came out to assist her. Not one even lifted the telephone...

Why Is Animal Testing Wrong

...Animal testing is wrong for various reasons. An animal test is any scientific experiment or test in which a live animal is forced to undergo something that is likely to cause them pain, suffering, distress or lasting harm. Examples of animal testing include: forcing mice and rats to inhale toxic fumes, force-feeding dog’s pesticides, and dripping chemicals into rabbits’ eyes. Animal experiments are not the same as taking your pet to the vet. Innocent animals used in laboratories are deliberately harmed, for a company’s benefit, and are usually killed at the end of the experiment. Everyone should care about animal’s rights because innocent animals are killed every day for no good reason. Some reasons why include, but are not limited to: alternative...

Experiments

...Examine the reasons why some sociologists choose to use experiments when conducting research. Study the reason why sociologist prefer to use experimental methods when carrying out a research There are many different types of experiments that can be conducted by sociologist, in order to help with the research that they are planning to carry out or just to help further prove their hypothesis. There are three main experimental methods that sociologists may choose to carry out their research/study. These three experimental methods are: Natural, field and Comparative. Each of these experiments has their own advantages and disadvantages. These positive and negative factors can analysed by practical, ethical and theoretical limitations and strengths that can be considered. This essay will be looking at each of these in detail. But, firstly what is an experiment? An experiment is a way of investigation a cause and effect relationship between independent variable and dependent variable. The first type of experiment that sociologist may choose to use in their research is, laboratory experiment. Laboratory experiments are conducted in a control setting, (this means that IV (The independent variable) and DV (dependent variable) can be controlled and manipulated by the researcher). Participant are given instruction to carry out certain tasks, in a normally manner. From this, the researchers are able to observe behaviour and be able to see cause and affect relationship between variables...

Psychology 1 Study Guide

...uncovering the mysteries of human and animal behavior are descriptions, explanations, prediction and control. Descriptions involve observing and taking notes on a behavior and explanation helps create theories. Prediction helps find out what might happen later on or in the future and finally, control seeks to find out how we can take a behavior we do not like and change it into one that we do. 2. Psychologists use the Scientific Method in research design so that they can reduce the amount of any kind of bias that could affect the research. They also use it to reduce the amount of errors in the experiment that might lead to inaccurate results. 3. Replication is taking a study and doing it over and over in the exact same way and managing to get the same results each time. This is important because it lends credibility to their research and allows other people who replicate the experiment an opportunity to predict behaviors and possibly control them. 4. Naturalistic Observation involves watching people in their normal everyday activities without getting involved. You would conduct this observation by going to their home and observing them live their lives without speaking or interacting with them. 5. In a case study you would gather all the information you could about the individual in extensive detail from birth to present. To conduct this you would have access to their medical records, interviews with their friends and family, school records, etc… 6. You would use a case study...

Ruby-Throated Hummingbird’s Color Preferences

...select their food based on color. Controlled Experimental Method: This test will include three bird feeders made of the same material, same size, placed at the same height but three different colors; red, blue, and green. Hummingbird feeders are made of glass or plastic. The feeders will be hung outside in the bird’s normal feeding environment near the woods. All three feeders will be filled with the same source and amount of water and equal amounts of sugar so that only the color will differentiate them apart. The feeders will be hung out for one week and observed at the same times of day. The times chosen were morning and dusk; 7 a.m. and 7 p.m. Results: Since this is a "thought experiment," you will make up results according to what you think might happen if you actually did the experiment.

Science for Everyday Life

...SC250-05: Science for Everyday Life Unit 9 Assignment August 05, 2014 When I hear the word “scientist” there are multiple things that run through my thoughts. I picture someone in a lab coat trying to discover a cure to a disease like cancer or the next plague that comes along. There is this image of dry ice coming out of test tubes and beakers surrounding them. Maybe even a bunch of stressed out yuppie looking guys who had way too much coffee, desperately trying to find the vaccine to stop the zombie apocalypse. I also picture Beaker from the Muppet show. He did a wonderful job forming an image of what a scientist probably was to me as a child. He was insecure and he made a mess. My cousin is a scientist so then there is an image of this very stern but sarcastic guy testing and testing and retesting. That image sounds so boring but I’m grateful there are brilliant minds like him out there. Scientist come in many different forms. They study and discover many different things. Over time there have been many types of scientist and they weren’t all wearing lab coats. Leonardo da Vinci was one I found interesting due to my love of art. He combined art and science in his sketches. He has amazing futuristic designs and even envisioned flight. Sadly he was a chronic procrastinator and had frequent disasters with his experiments of new techniques (Leonadoda-Vinci). Galileo Galilei was an Italian scientist who developed the telescopes and started to observe the solar system...

Social and Multicultural Psychology

...Social Psychology and Multicultural Psychology Jennifer Wolf Psych/620 Instructor- Jean Thorndike Social Psychology and Multicultural Psychology This paper defines social psychology and multicultural psychology. Described within will be the primary research strategies used in social psychology. Provided will be examples of each strategy. An explanation regarding how social and multicultural psychology are related and what separates social and multicultural psychology into two distinct fields will be provided. Social Psychology Social psychology is “the scientific attempt to explain how the thoughts, feelings, and behaviors of individuals are influenced by the actual, imagined, or implied presence of other human beings” (Fiske S. , 2010). Social psychology tries to explain how an individual reacts to another individual whether the individual is present or not. Social psychology also attempts to explain how an individual acts in a group setting as well as how an individual acts when a person (s) of authority is (are) present. Primary Research Srategies1 The three primary research strategies used in social psychology are descriptive research, correlational research, and experimental research (Fiske S. , 2010) Descriptive research “aims to depict accurately some characteristic in a population of interest” (Fiske S. , 2010). Descriptive research deals with one variable at a time and averages the responses to said variable. For example, a public opinion survey such as...

The Negative Effects Of Animal Testing On The Environment

...US Statistics states, roughly 11-25 million animals are used in conjunction with research, more specifically the testing process. When it comes to animal testing there are several environmental conditions that are affected and bypassed by several individual, or research facilities. It is important to recognize and understand the negative consequences of animal testing with regards to our environment. It is essential that the effects of animal testing on the environment be brought to light on a factual level as opposed to an opinionated thought. Through the years there has been exponential growth in the use of animals in experiments, especially with the testing of soon to be consumer products. This noticeable and documented increase has directly impacted environmental pollution. This expansion of animal testing, has created laboratories to produce more byproducts. While the majority of laboratories do not participate in recycle programs, developing an amplification of waste in the environment. Bedding, needles, syringes, and other biohazards are not disposed of properly because of the lack of laboratories using the recycle...

Accessibility Theory

...viewed. (Fazio & Roskos –Ewoldsen, 1994 P. 85) Accessibility Theory complements the Reasoned Action Theory and the Theory of Planned Behavior approach because people carefully consider the consequence of behaving in a particular manner and weigh out the pros and cons of situation. When all else fails the decision is based more on spontaneity, channeling a thought or memory. The decisions however can also be based on how accessible attitudes are and how likely objects, good or bad can capture the attention of a person. Research supports these propositions (Krays, 1995) because studies found that individuals who were in touch with favorable attitudes toward a certain topic or product were more inclined to select or choose those with less accessible attitudes. Attitudes play a very important role because they range from strong attitudes to weak attitudes. When a person has a strong attitude toward something most likely the persons mind is made up and set in his or her ways. Vice versa with a weaker attitude which is more susceptible to change. When strong and weak attitudes are already implemented in the mind, thought and memory are automatically activated. Accessibility is also known as “getting in touch with your feelings”. This also can be described as association. Accessibility and association go hand in hand because the more frequently that people mentally remember the association between an object and evaluation the stronger...

The Scientific Method

...Question. The Observation and Questioning step is very important. In this step we look at what we want to do an experiment on. In the Hypothesis step, you guesstimate what the outcome of the experiment will be. I feel that the Testing step is self-explanatory. In this step you perform your experiment and test the hypothesis you came up with in the previous step. After you perform your experiment, you have the Results step. This is where you have your outcome. If your outcome supports your hypothesis, then you are able to go onto the next step of the process. But there are times that your outcome will be different than your hypothesis, if this is the case you go back to the beginning of the process. If this happens, you have to do all of the steps all over again. Next we have the Explanation step. You need to figure out an explanation that addresses the question that you are experimenting. The final step is the New Question step. Here you come up with the conclusion to your experiment. Quite often your conclusion could lead to a whole new set of questions, in which would lead to new experiments (Axia College, n.d.). For the online experiment, I picked the question of “Have you ever wondered why the plant grows toward the window?” For my hypothesis I chose, “plants respond to the light which they need to make their food.” My prediction for this experiment was “If it is true that plants respond to the light which they need to make their food and I grow three plants...
