Phase II - Part V - Tyler Orner
Concept: A concept is just an idea or a notion. For example, a computer or technology would be a concept. There are many different types of computers but each one would fall under the general concept of a computer and an even broader concept of technology.
Prototype: A prototype is the first of its kind. First we create what we know to be concrete and use that as our prototype, and then comparing all subsequent objects to our prototype. One prototype is the hybrid car. The manufacturers had to create a prototype for the design to determine whether the idea was feasible and if it would be popular. Once it was determined that both would be possible, they began to mass produce cars similar to this prototype.
Algorithm: An algorithm is a step-by-step method that is followed to get to a certain outcome. One type of an algorithm is factoring. We know that if we have a function and we follow a standard procedure we will find the answer. Also, PEMDAS, or the order of operations is an algorithm because if we follow it, we are certain to get the correct answer.
Heuristic: A heuristic is a simplified way of finding a certain outcome, but this way is more error-prone. One example of this is trying to solve a hangman puzzle. One will first guess letters like r, s, t, l, n, and the vowels because they are the most common letters. While it is possible that the word may contain a letter like y or z, it is less likely so we don’t guess that until the end. Also, for word searches, if a word has a unique letter combination or two of the same, it is easier to just look at those in the puzzle. While this may not always lead to the answer the first time, it is faster than looking at each letter individually.
4. One way to use my knowledge of this chapter to improve the learning strategy is to first categorize a chapter or the desired material into main concepts to make the wide variety of material covered into a simplified few concepts. Another way is to create a prototype to just a get a base strategy which I can then tweak and improve as I go.
6. I am going to break the information down into simplified concepts to make the variety of material covered easier to remember and associate for the students.
Phase II - Part IV - Tyler Orner
Hippocampus: The hippocampus is a part of the brain that is responsible for processing explicit memories. A limbic system structure, the hippocampus captures new explicit memories of names, images, and events. Damage to this system can disrupt some types of memory. Damage to the left hippocampus have trouble remembering verbal information but have no problem recalling visual designs and locations. For people who have damage to the right hippocampus, this situation is reversed.
Recall: Most people associate memory as recall, or the ability to retrieve information not in conscious awareness. Recall can be defined most simply as the measure of memory in which the person must retrieve information that they learned previously and indentify it without any help. A fill-in-the-blank test examines how much a student can recall.
Serial positioning effect: Serial positioning effect refers to the idea or concept that we usually remember the first and last terms in a list the best. This most likely occurs because the last terms are still in our short term memory and the first terms are the ones that have been practiced the most, while the terms in the middle are usually the ones that are most likely forgotten.
Recognition: Recognition is a measure of memory where the person only needs to indentify items previously learned. This is different than recall because in recognition, people only need to “recognize” information rather than needing to have to “retrieve” the information. A multiple choice test is a common example of testing recognition.
Relearning: Relearning is a measure of memory that assesses the amount of time saved when learning material for the second time. If someone has learned a skill but then never uses it for an extended period of time, they may forget it. So when they need to use it again, they must relearn the skill. The amount of time they save learning this skill the second time is relearning. An example of this would be a person who learns chemistry in high school but then becomes an elementary teacher. They will not use the skill, but maybe the school will decide to teach chemistry in the grade that this teacher teaches, in which case he or she must relearn chemistry. Theoretically, the skill will be easier to learn and will take less time to learn the second time.
Priming: In order to retrieve a memory you must identify the “strand” that triggers the memory. This action is not always a conscious act but is necessary for the memory to be recalled. Therefore, priming can be defined as the activation of particular associations in memory.
Mere-exposure (not in 9): The mere-exposure effect is the phenomenon that frequency creates or breeds fondness. Repeated exposure to a certain novel stimulus will usually produce an increased liking of that stimulus.
4. Maslow states that the lowest level, or base level, of needs must be satisfied first before we can begin to think about the second level/tier of needs. In the first level is our food, water, air. Then we begin to move on up from there. This can be applied to learning and memory. If someone’s needs for a more basic level have not been satisfied then the learning and memory will not be fulfilled until that need is filled. To take it to the extreme, if someone is starving; they will first satisfy their need for food before they try to learn. Another example comes when someone suffers the loss of someone close to them. They will feel a need for lovingness and until this is satisfied they will be unable to learn. This happens in school. If a student loses a family member, often their grades decrease because they are trying to satisfy a more important need. Finally, in the wake of a tragedy like 9/11 people are unable to learn or remember. When it happened people who experienced the event had trouble recalling some details because they needed to satisfy their need for safety first. Even in third grade, our teachers stopped teaching and they made us read alone while they discussed what happen amongst the other teachers. They were fulfilling this other need first.
Phase II - Part II - Tyler Orner
8. I feel that grades do fall under this Chapter. For example, if one person sees that someone received a good grade, they are likely to try and reciprocate the actions of the person who got a good grade. This could be interpreted as observational learning. Also, just receiving a grade alone will be operant conditioning because a good grade is reinforcing the positive behavior of hard work and studying whereas a bad grade also reinforces the same desired behavior of hard work and studying.
9. I do agree with this positive bias that Skinner’s research had on operant learning. For mainly one reason, a lot of his methods are still in use today. One example is how teachers teach their classes. The successful and good teachers are the ones that individualize their class for the students that they have in them. Another example is in the workplace. Employers may give raises or rewards, whether monetary or not, to employees who are successful in reaching their goals, targets, or just doing a job-well-done.
C. The students in this class learn in all different types of ways. Some of the more common and reoccurring answers were that the students learned by listening to lectures (auditory), looking at pictures and diagrams (visual), and others learned best by reading and writing notes. This will be helpful into designing our project because it will allow us to structure our style towards fitting and incorporating everyone’s needs. One way to do this is to create a PowerPoint for our visual learners, lecture about it for the auditory learners, which then allows the remaining students to take additional notes.
Phase II - Part I - Tyler Orner
Research after Skinner: Skinner believed that behavior was shaped by external experiences, rather than thoughts. So he felt that we should give rewards to promote a desirable behavior and not worry about a person’s freedom or dignity. He believed that in the classroom, individualized instruction should be performed, which has begun to occur and studies have been conducted to determine whether this and the use of positive reinforcements have a positive impact on the grade a student receives. Recently researchers have studied the effects of primary and secondary reinforcers. While many were and still are critical of Skinner, his ideas are currently in existence today.
(The following apply to observational learning)
Modeling: Modeling is the process of observing and imitating a specific behavior. From this is where we can trace many of our social behaviors. What we see or observe, we do ourselves, and this is modeling.
Mirror neurons: Mirror neurons are frontal lobe neurons that fire when performing certain actions or when observing another doing so. The brain’s mirroring of another’s action may enable imitation, language learning, and empathy.
Albert Bandura: Albert Bandura is one of the original researchers when it comes to dealing with observational learning. Bandura’s experiment with the children outlashing against the Bobo doll shows that children, and others, tend to observe certain behaviors from others, and when they are faced with certain situations they are likely to act in a similar fashion. His findings can help explain why some connections exist. For example, they may help explain why abusive parents tend to have aggressive children.
Prosocial models: Prosocial models are positive, constructive, helpful behaviors. Prosocial models can help change people actions or influence their actions to be positive or socially pleasing based on their own actions.
The impact of television (dun dun dun): (page 338) During the first eighteen years of someone’s life who lives in a developed country, they are more likely going to spend more time watching TV then they will spend in school. With so many violent shows on, especially during prime time hours for these children, through observational learning, children are more likely to repeat these violent of negative behaviors.
The good news about TV (from Chapter 1): (page 338) If a child sees prosocial behavior on the TV and is frequently exposed to positive behavior, then the child is most likely going to act in a more positive way in society.
Desensitizing of youth: (page 340) By watching more TV, and the violence that occurs, the youth are likely to pick up on what is happening and learn by observing what is happening on their show. When this occurs, they become less likely to react or respond when an actual violent crime occurs in real life.
Provide one example of Observational Learning from your lifetime (make sure that each group member has their own example to post to the blog): In soccer, I watched my favorite player do a move that would continually beat players over and over again. The move was quite easy but if done properly could be very deceptive. I practiced this move and have since used it to my advantage. Another example is when I saw two kids get into a fight and then their consequences. By seeing the outcome, I learned to not do what they did, in this case fight.

Phase 2, Part 5~Collin Brown
Babbling Stage- The part in a baby's life when they can form sounds that do not necessarily make sense, but are sounds none the less. A baby saying ga-ga has no real meaning and is an example of babble.
One-Word Stage- After turning one, the baby can say words with a conveyed meaning that are usually only one word or syllable. The baby word, "ba-ba" can be used when reaching for a bottle. The word kind of sounds like bottle and is therefore conveying a meaning.
Two-Word Stage- Before reaching the age of two, babies can say two-word sentence fragments. Babies sometimes say things like "hold you" (something I used to say when I was little), when they wanted to be held.
Telegraphic Speech- Speech that is fragmented and contains mostly just nouns and verbs but can fully convery a meaning. Phrases such as "THEY'RE HERE. ENTER BUILDING" are short, convey meaning, are fragments of sentences, and are commonly used in telegraphs. This type of writing is a good example of how most babies speak in the two-word stage.
Linguistic Determinism- The language we speak and understand has a direct influence on how we think and comprehend things. In French, every noun has a gender. Therefore, French people perceive common items as he/she through language.
Phase Two Part Six
1. Reading/Memorizing:
Have a representative sample of people read an article based on neuroscience. Have the sample of people come up with a varitey of numonic devices in order to memorize the infromation.
2. Visual Aids/Demonstration:
Have an instructor demonstrate neuroscience to a representative sample of people through a brain activity. After, have students make some sort of of visual aid to use for their own learning experience.
3. Lecture/Listening:
Have a neuroscience professor lecture to a repreesentative sample of students on the topic of neuroscience for about an hour. Record the lecture on a recording machine and listen to the lecture before one goes to bed.
4. Reading/Writing Notes:
Have a representative sample of students read an informational essay on neuroscience. Throughout the reading session, make notes that would cover main topics essential for the chapter.
5. Hands on/Project:
Have a representative sample of students build a model of the brain and label each part and its functions. Present the structure in front of the class and have students actually hold the structure.
6. Video/Audio:
Have a representative sample of students create a video or album based on neuroscience. The video should include the necessary visuals along with appropriate concepts and terms.
Phase 2, Part 5, Question 5
Phase 2, Part 3
When we present this data in December, we will have bar charts to show which strategies are used most by students at Wilson High School and correlation studies among hours studies per night and grades. The information will be easy to understand when we categorize and break down the information from each survey. I believe our data will be helpful and useful to us as well as others.
Our tool for collecting data was most definitely useful and somewhat accurate in collecting the information because it helped us determine what most successful students do in order to study and receive good grades. We also determine what learning strategy helps students learn the material the most. This survey gave us a basis and will help us start building our learning strategy. To supplement our data we could have used a random sample and also collected more responses from all ages. We could also have reached out to students beyond Wilson in case the different schools condition students to learn in a certain way.
This data can apply to the real world since it asks what strategy helps students learn better. This can transfer to college and eventually to the work force when one has to be trained for a job. One must learn and remember information for a career, not just memorize and forget the information later. The data could be useful to teachers and coaches. Coaches who want their players to remember specific plays could benefit from useful learning strategies. We will share our data with or teachers and coaches in hopes that the information will be considered and used. Then hopefully through these strategies, students will become more successful in class and life.
Phase 2, Part 4, Question 5
Gardner- The theory of multiple intelligences relates to Bloom's theory in that it breaks up categories for certain types of learning, but breaks them down into 8 categories instead of 3. It ties into memory specifically by relating to different people's ways of memorizing. By analyzing the ways certain people learn in a classroom setting, we can attend to each individual learning style of the student.
Phase 2, Part 4 ~Collin Brown
Mnemonics- Help to remember order or long passages. It uses association of visual items with the thing you are supposed to memorize. By visualizing the object, the word will come by association. Also, these devices can be applied using sound associations. Creating a song to remember order of something is an example of a mnemonic.
Ways to Organize Information for Encoding:
Chunking- A way to recall information by grouping words into groups that make sense to us. this can also occur with numbers. Eats Cake Boy is less easily memorized than Boy Eats Cake.
Hierarchies- Association with an expertise in an area. People use concepts from this expertise in order to memorize by using the concepts that relate to the information. I could associate memorization with rankings of the best lacrosse teams in the nation. Comparing the best part of the data to the best team in the nation.
Memory Trace- Recalling information based on a cue that reawakens that certain information. Helps us retrieve information that lies in long term, sensory, or short term memory.
Iconic Memory- Instant photographic memory. Our eyes can take in detail from an image in very small amounts of time. We can produce this image in our minds with precise detail. The card memory game with flipping and matching cards. Our memories can remember where the matching card is from seeing it only for a second.
Echoic Memory- Instant sound memory. Works in the same way as iconic memory but with sounds that are heard instantly instead of pictures being seen. This form of memory is more unstable than iconic memory. Memorizing song lyrics or commercial jingles are forms of echoic memory.
Long Term Potentiation- Strengthening of potential neural firing by stimulating memory neurons. It results in less prompting to release a neurotransmitter and increased receptor sites. It helps for learning and remembering by association.
Amnesia- The inability to formulate new memories or have old ones. Can occur from brain damage. Some people with amnesia can learn certain special memory skills but have no recollection of having learned the skill. In the movie 50 First Dates, Drew Barrymore forgets the day before everyday after she has a vicious accident. When Adam Sandler goes to make to her, he sees that she has painted a lot of pictures of him but has no idea why she did it.
Phase 2, Part 2, Questions 4 and 10~Collin Brown
Question 10- I play the game of lacrosse based on what I see at the highest level of play. If I see a good player doing something that works, I will use it. It applies psychologically in classical conditioning. I associate good players with knowing what they are doing because it got them to that point. In biology, my mind is processing a new move to use.
Phase 2, Part 1 ~Collin Brown
Conditioned Reinforcers- Conditioned Reinforcers are learned reinforcers that are associated with primary reinforcers. If getting milk and cookies is usually occurring right before sleep, the person need milk and cookies to go to sleep. The milk and cookies are the conditioned reinforcers.
Immediate Reinforcers- Immediate reinforcers provide the wanted result immediately after the performed action to get the reinforcement. For example, the loss of hunger after eating comes immediately after eating a lot.
Delayed Reinforcers- With Delayed Reinforcers, the wanted result comes later than the performed action. No learning may occur in non-humans because most animals do not have the patience to wait for the next reinforcer. Humans are only sometimes conditioned to delayed reinforcers. For example, a person will wait in a line at the amusement park to ride one ride. Waiting in line takes a long time, but the reinforcement is the ride.
Reinforcement Schedules:
Fixed-Ratio- Steady reinforcers that come after a set number of responses. For example, after hitting a button five times, a rat receives food.
Variable-Ratio- The reinforcers occur randomly after the responses. If Reinforcers go up, the responses go up. For example, entering a raffle is on a variable ratio schedule.
Fixed-interval- Reinforce the response after a set time period. The number of responses greatly increases as the reinforcement time gets close. The pay-stub at the end week makes workers work harder closer to when they are going to receive their pay-stub.
Variable-interval- Are reinforced after a random amount of time. Slow, steady responses occur because reinforcers can occur at any time.
Punishment- is the opposite of reinforcement. It decreases the amount of responses instead of increasing the amount of responses, or wanted behavior. There are drawbacks however, including doing the unwanted behavior where punishment is absent and increased aggressiveness and anger towards the punisher. Punishment includes putting a dog into a cage if he bites someone.
Cognitive Map- A cognitive map is developing and idea or representation of what someone is looking at or exploring. If a new student is in a school and is learning his/her way around, this is building a cognitive map.
Latent Learning- Someone being demonstrated as learning something with evidence only when a reward is present. Boy in a new school is told to find a certain room in order to win a prize. He will automatically recall his cognitive map better because he has a drive.
Intrinsic vs. Extrinsic motivation- Intrinsic motivation is wanting to do something for your own wants, such as pride, while extrinsic motivation is wanting to do something for rewards or to avoid punishment.
How does cognition impact operant conditioning?- The cognitive processes determine what we think, perceive, and expect to happen. This impacts operant conditioning by following the rules of conditioning. If we think something will provide reinforcement, we will do it, if not, we will not do it. The mental processes that determine what we do impact how we respond to conditioning.

Phase 2, Part 5
Language: Language is the human capacity for a way to communicate through spoken, written or signed words to combine them as we think. There are several different languages around the world. Some examples are Spanish, Chinese, French, Latin, Arabic, and sign language. All different languages combine to form different sentences and meanings.
Phonemes: Phonemes are an essential set of basic sounds. They are a small segments of sounds to form meaningful words from sounds. For example in the words kit and skill the phoneme is the "k" sound in the word.
Morpheme: A morpheme is the smallest unit of language that carries meaning. Morphemes are usually a combination of tow or more phonemes. However the words "I" and "a" are morphemes as well as phonemes. The word "unbreakable" contains three morphemes: "un," "break," and "-able."
Grammar: Grammar is a system of rules that allows us to communicate. It is the composition of sentences, phrases, and words under the rules of semantics and syntax. Some grammar parts are the usages of commas and the structure of sentences with nouns, verbs, and adjectives.
Semantics: Semantics are a set of rules we use to derive meaning and relationships from morphemes, words, and sentences. There are denotations (direct meanings) and connotations (implied meanings). For example the phrase "Raining cats and dogs" can have two meanings derived from semantics.

~~Amanda
Phase 2, Part 4
Memory loss: Memory loss occurs when memories that used to be remembered, can no longer be retrieved. Memory loss can be partial or total and can come with aging or can be caused by brain trauma. An example of memory loss by a medical problem is Alzheimer's disease.
Memory feats: Memory feats are when one has a memory that is much greater than the average person. There is incredible remembrance of words, digits, orders, and many other things. For example, a person may have a great memory feat when they can remember a very large number of the numbers of pi. Or if a couple decks of cards are shown in a random order and the person can remember the order and put it in the order.
Memory like a computer? The memory is like a computer of how it receives information through encoding, retains the information through storage, and gets is back from retrieval. Like a computer and the keys changing into different meanings on the computer, the sensory information is changed into a neural language so the brain can store and remember it.
Sensory memory: Is the immediate initial recording of sensory information after the original stimulus. The memory is temporary and is only the initial part. Part of sensory memory is iconic memory and echoic memory. Iconic memory is when you see something for a short amount of time and echoic memory is when you remember something by auditory. For example sensory memory could be in class when you are talking to a classmate and your attention is on the classmate and the teacher is giving a lecture and someone asks you what the teacher said. You may be able to remember some of the last words the teacher said.
Long term memory: Long-term memory is usually a permanent type of memory that is stored for later retrieval. Long-term memory is essentially limitless and memories become long-term memories through the meaningful associations and rehearsal. For example, long term memory occurs when people everyday remember and learn peoples names. Names are usually permanent in memories and even after years, names can usually be retrieved from the memory.
~~ Amanda
Phase 2 Part 1
Law of effect: Law of effect is defined as "Rewarded behavior is likely to recur." If a subject associates a good reward with a behavior, the subject will usually do the behavior again in hopes of the same reward. For example when a dog performs a trick and receives a treat.
Skinner box (operant chamber): An experimental chamber in which an animal, usually rat or pigeon, presses or pecks on bars or keys to release food or water as a reward. the chamber records the responses and experiments on operant conditioning.
Shaping: Skinner used shaping in his experiment where he used reinforces such as food to change and guide an animal's actions toward a certain wanted behavior. For example, shaping occurs when one tries to train a dog how to do a trick or go to the bathroom outside.
Successive approximations: After first observing how a subject reacts before training, an experimenter would continue based on the initial behavior. By changing rewards and rewarding responses that are closer to the desired behavior. The next time, take a step closer to the desired behavior before they are rewarded until the behavior is reached.
Discriminative stimulus: Discriminative stimulus test if a subject can discriminated between different shapes, colors, sizes, and objects. With one actions or experiment of the same object, but just different shapes or colors, a subject could react one way with one shape but different with another. For example, if a dog learns to bark upon seeing a blue ball, but lay down upon seeing a green ball of the same shape and size.
Reinforcement: Reinforcement is the action or an event that causes the first action to occur more often. Reinforcement is anything that increases a behavior.
Positive reinforcement: Positive reinforcement is when a subject is given something as a stimuli after a behavior. This would make the subject do the behavior more often. An example is giving a child encouragement and praise after cleaning their room.
Negative Reinforcement: Negative reinforcement is when a stimulus is removed. This can also increase the likelihood of a behavior. An example is when a child is whining and the parents take away the toy. Also detention is taking away a student's time.

Phase Two Part Five Question Six
~~Tyler T
3.To use thinking and language in our learning strategy we will use mnemonic devices so students can make relationships and connections to the information they are learning. Therefore, the information will be stored and ready to be retrieved by an easy fashion.
~~Amanda
4. To use critical thinking and language, we could incorporate class discussion because this would allow us to gain the perspectives of all other students. More information, in all different opinions, would "stick" in our mind.
~~Maggie
5. To use language in an abstract way, we could group words together through chunking. This is when we group words or numbers into phrases that make sense so that we can remember it easier. For example, if we are given the words eat, cake, boy. We can rearrange them to make a phrase that is easy to remember and comprehend; Boy eats cake.

Phase Two Part Five Question Three
Phase Two Part Four Question Three
Monocular Cues
Monocular cues deal with items that can be process with one eye. Relative size, texture gradient, aerial perspective, and linear perspective are the main components that make up monocular cues. In relative sizing, if two objects are roughly the same size, to object that looks the largest will be judged as being the closest to the observer. In texture gradient, when one is looking at an object that extends into the distance, the texture becomes less and less apparent the farther it goes into the distance. In aerial perspective, objects that are farther away seem to be blurred or slightly hazy due to atmosphere. Lastly, linear perspective incorporates the idea that parallel lines appear to meet as they travel into the distance. For example, the outer edges of a road seem to grow closer and closer until they appear to meet. The closer together the two lines are, the greater the distance will seem.

How can understanding classical and operant conditioning help us to understand the way we learn?
First example: When a teacher tells us to clear their desks, we automatically think that there will be a quiz. This is because we have been classically conditioned. As young students, the first time we were told to clear our desks we had no clue what was going on. Then the teacher gave us a pop quiz. As a result, we think that whenever we are told to clear our desks there must be a pop quiz, even though this is not always true.
Second example: If someone driving a car sees the stoplight turn red, then he knows that he should stop. The reason that he learned this is because one time he ran the stoplight and ended up getting a ticket. He remembers that he was really upset and frustrated about having to pay a lot of money; therefore, whenever he sees a red light he knows that he should stop because of the negative reinforcement, paying a fine.
Do you think that either plays a role in how you respond to teachers and your academic role here at Wilson?
~~Maggie Lawrence
I also believe that operant conditioning plays a large role in how I respond to teachers and my academic role in Wilson. I know that when I study, I hopefully will receive a good grade. After I receive a good grade, generally teachers will acknowledge my hard work. Therefore, I have been conditioned that when I study, I receive good grades and "praise." From this conditioning, I will most likely always study since I expect and want good grades.

Compare Classical and Operant Conditioning
Sunday, November 14, 2010
Biology's Role in Learning
Real Life Scenario for Operant Conditioning
Real Life Scenario for Classical Conditioning
Example:
An elderly woman has a fluffy down pillow with some of the down sticking out of the fabric at her local retirement center, Apple Springs. When she first goes to bed and tries out the pillow, a piece of down tickles her nose, which makes her sneeze. This happens every time she goes to bed. Soon she sneezes every time she lays down on any kind of pillow at Apple Springs.
Explanation:
The unconditioned stimulus is that the down tickles the nose of the elderly woman. The unconditioned stimulus is that the elderly woman sneezes. When the down tickles the nose is combined with the type of pillow, the conditioned stimulus, the conditioned response becomes that the woman sneezes.
Example of Classical Conditioning
An example of classical conditioning would be the following:
In order to treat bedwetting, a pad that is sensitive to dampness is placed under sheets. When this pad becomes wet, it sounds an alarm and you wakeup. Eventually you don’t need the alarm to wake up and your bladder will wake you up.
The unconditioned stimulus is the alarm, which also makes the waking up an unconditional stimulus. One the alarm is paired with the full bladder, the conditioned response is to wake up.
Aquisition
Acquisition refers is some of the first stages of learning when a response is created or established. When concerned with classical conditioning, acquisition is the period of time when the stimulus reveals the conditioned response. In other words, acquisition is the initial stage of the learning or conditioning process. In this stage, some response is being associated with some stimulus to the point where one may say the organism has received the same response. During this stage the response is strengthened so that the topic is truly learned.
Ivan Pavlov's Experiment (Outlines, Goals, and Findings)
Outline and Goals:
In a series of experiments, Pavlov tried to figure out how saliva and lab coats were linked. This was his outline. Ivan noticed that people who were in lab coats made the dogs drool. This was because the scientists would feed their dogs in lab coats. In order to figure out this phenomenon, his goal was to strike a bell when the dogs were fed. If the bell was sounded in close association with their meal, the dogs would hopefully learn to associate the sound of the bell with food. After a while, at the mere sound of the bell, Ivan expected them to respond by drooling.
Findings:
Pavlov worked on the conditioned reflex, a fundamental aspect of learning. He showed that if the presentation of food to a dog was repeatedly accompanied by the sound of a bell, then the dog would respond by coming to the bell as if it was food. Pavlov regarded salivation on sight of food as an unconditional response and the subsequent salivation on sound of bell alone as a conditional response. Salivation in response to food was unlearned and was the unconditioned response. The unconditioned food stimulus was the food because the food in the mouth unconditionally starts salivation. Now, the conditioned response is the salivation , while the conditioned stimulus is the bell sounding. In addition, he is responsible for many of the basic concepts and can be regarded as the founder of the experimental study of animal learning. Pavlov also discovered that these reflexes originate in the cerebral cortex of the brain.
