New cards
Learning
is a relatively permanent change in an organism's behavior due to experience that leads to the acquisition of skills and knowledge.
2
New cards
Classical Conditioning
a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.
3
New cards
Ivan Pavlov
A man who experimented with animals to study different types of learning and conditioning of animals. His most famous is his experimentation with dogs.
4
New cards
Pavlov’s experiments with dogs
Pavlovian Conditioning-Starts with the before conditioning where a dog will salivate when it sees food. Then, a bell is introduced and the dog has no response. Then, the bell and the food is combined to prompt salivation. Finally, after conditioning the dog would respond to the bell with salivation.
5
New cards
Unconditioned Stimulus
unconditionally, naturally, and automatically triggers a response. For example, when you smell one of your favorite foods, you may immediately feel hungry.
6
New cards
Unconditioned response
The unlearned response that occurs naturally in response to unconditioned stimulus. For example, the feeling of hunger after you smell the food.
7
New cards
Conditioned Stimulus
Previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
8
New cards
Conditioned Response
The learned response to the previous neutral or conditioned stimulus. For instance, the conditioned response would be salivation when the bell is heard.
9
New cards
Neutral Stimulus
A stimulus that does not initially elicit a response.
10
New cards
Acquisition
is the stage of the conditioning process and occurs when a response is established. (how the learning is acquired). Links and neutral stimulus and unconditioned stimulus.
11
New cards
Extinction
involves the gradual weakening of a conditioned response. In classical conditioning, extinction occurs when the conditioned stimulus is no longer presented with the unconditioned stimulus.
12
New cards
Spontaneous Recovery
is the reappearance of a response (a CR) that had been extinguished. The recovery can occur after a period of non-exposed to the conditioned stimulus. It is called spontaneous as it seems to appear out of nowhere.
13
New cards
Stimulus Generalization
is the tendency for the conditioned stimulus to evoke similar responses after the response has been conditioned.
14
New cards
Second order conditioning
an animal that has learned that a tone predicts food might learn that a light predicts tone and begins to respond to the light alone.
15
New cards
higher order conditioning
A conditioned stimulus in one experience is paired w/ a new neutral stimulus creating a 2nd conditioned stimulus.
16
New cards
cognitive processes
any of the mental functions assumed to be involved in the acquisition, storage, interpretation, manipulation, transformation, and use of knowledge.
17
New cards
biological predispositions
an increased chance of developing a disease or pattern of behavior based on the genes we inherited from our parents
18
New cards
Robert Koelling-Taste aversion
a conditioned ___ ______ can occur when eating a substance followed by an illness. studied taste aversion in rats noticing rats would avoid water in radiation chambers
19
New cards
associative learning
is learning in which an organism learns that certain events occur together. (ex. knowing a cat will be fed when a certain person gets home from work).
20
New cards
Behaviorism
is based on the assumption that learning occurs through interactions with the environment.
21
New cards
Operant behavior
refers to behavior that operates on the environment or is controllable by the individual that produces some type of consequence.
22
New cards
respondent behavior
are behaviors that occur as an automatic response to some stimuli. For example, the pupil starts to flicker when esposed to direct sunlight.
23
New cards
Mary Cover Jones
Gave a child positive reinforcement to get them to unlearn a response to a stimulus. Helped to use counter conditioning.
24
New cards
counter conditioning
Behavior therapy procedure that is used to evoke new responses to a stimuli that are triggering unwanted behaviors.
25
New cards
Stimulus discrimination
in classical conditioning, ______________ is the ability to differentiate between a conditioned stimulus and other stimuli that have no been paired with an unconditioned stimulus.
26
New cards
John Watson’s little Albert Experiment
demonstrated that classical conditioning could be used to create a phobia. A phobia is an irrational fear, that is out of proportion to the danger. In this experiment, a previously unafraid baby was conditioned to become afraid of a rat.
27
New cards
B.F Skinner Rat and Pigeon Experiment
The psychologist used a device that emitted a clicking noise to train pigeons to peck at a small, moving point underneath a glass screen. Skinner posited that the birds, situated in front of a screen inside of a missile, would see enemy torpedoes as specks on the glass, and rapidly begin pecking at it
28
New cards
Operant Chamber/Skinner Box
comes with a bar or key that an animal manipulates to obtain a reinforcer like food or water. The bar or key is connected to devices that record the animals response.
29
New cards
Shaping
Gradually molding or training an organisim to preform a spesific response (behavior) by reinforcing any responses that are similar to the desired response.
30
New cards
Positive Reinforcement
are favorable events or outcomes that are presented after the behavior. In situations that reflect positive reinforcement, a response or behavior is strengthened by the addition of something such as praise or a direct reward. (for example giving someone a sticker)
31
New cards
Negative Reinforcement
involve the removal of an unfavorable event or outcome after the display of a behavior. In these situations, a response is strengthened by the removal of something considered unpleasant. (taking aspirin to remove a headache)
32
New cards
Aversive conditioning
form of counter conditioning that associates an unpleasant state (such as nausea) with an unwanted behavior(such as drinking alcohol)
33
New cards
Vicarious Classical conditioning
Occurs when a subject is exposed to someones elses fears or reactions and then internalizes those feelings, actions, and reactions for themselves
34
New cards
Contingency
is the relationship between two events, one being contingent or a consequence of the other event.
35
New cards
Chaining
occurs when animals are taught to preform a number of responses successively in order to get a reward. Goal is to link together a number of seperate behaviors into a more complex activity. (training a rat to do a bunch of different things to eventually chain them together into the rat going through an obstacle course).
36
New cards
law of effect
states that if the consequences of a behavior are pleasant, the stimulus-response connection will be strengthened and the likelihood of the behavior will increase.
37
New cards
Generalized Reinforcers
a stimulus which has acquired reinforcing properties through repeated pairings with other reinforcers under various situations; the stimulus (which was previously neutral) now becomes reinforcing for many behaviors.
38
New cards
Successive Approximations
a method of shaping operant behavior by reinforcing responses similar to the desired behavior. Initially, responses roughly approximating the desired behavior are reinforced. Later, only responses closely approximating the desired behavior are reinforced.
39
New cards
Operant Conditioning
is the method of learning that occurs through reward and punishments for behavior. Through these rewards and punishments, an association is made between a behavior and a consequence for that behavior.
40
New cards
Observational Learning
is the process of learning by watching the behaviors of others. The targeted behavior is watched, memorized, and then mimicked. Also known as shaping and modeling, observational learning is most common in children as they imitate behaviors of adults.
41
New cards
instrumental learning
s a type of learning in which behaviors are strengthened or weakened by their consequences. if a student is rewarded with praise every time she raises her hand in class, she becomes more likely to raise her hand again in the future.
42
New cards
Instinctive drift
is the tendency of some trained animals to revert back to instinctual behaviors. In other words, they will behave in accordance with the unconscious and automatic behaviors, as opposed to the operant conditioned behaviors.
43
New cards
John Garcia Rat Experiments
demonstrated that a rat would associate a taste, but not a light or sound, with illness. In contrast, pain could be associated only with a visual or auditory cue, not a taste.
44
New cards
Robert Rescorla
was an American psychologist who specialized in the involvement of cognitive processes in classical conditioning focusing on animal learning and behavior
45
New cards
Rosalie Rayner
was a research psychologist, and the assistant and later wife of Johns Hopkins University psychology professor John B. Watson, with whom she carried out the famous Little Albert experiment
46
New cards
Edward Thorndike
Conduced operant conditioning with the cat puzzle box. He would place the cat into the box and once they were successful they would be rewarded. The cat would escape through trial and error and would eventually memorize the steps to get out. If the action brings a reward he believes that the action is stored in the mind and to be replicated.
47
New cards
Positive Punishment
sometimes referred to as punishment by application, involves the presentation of an unfavorable event or outcome in order to weaken the response it follows. (For example, adding a parking ticket/fine so now you will no longer park illegally).
48
New cards
Negative Punishment
also known as punishment by removal, occurs when a favorable event or outcome is removed after a behavior occurs. (time out, revoking your license). (for example removing a cell phone to decrease bad behavior).
49
New cards
Omission training
a method in behaviorism used to stop undesirable behaviors. When a subject (the person/animal being trained) enjoys something and it is taken away as punishment for an action or behavior. A child will try to improve a behavior if something they love will be taken away.
50
New cards
escape conditioning
a person’s behavior causes an unpleasant event to stop. For instance feeding a dog vegetables in order to avoid the unpleasant event of eating vegetables.
51
New cards
avoidance conditioning
involves the training of an organism to withdraw from an unpleasant stimulus before it starts. A child avoids unpleasant consequences because of past behavior.
52
New cards
over justification affect
occurs when an external incentive such as money or prizes decreases a person’s intrinsic motivation to preform a task.
53
New cards
partial reinforcement
results in slower acquisition of a response, but a much greater resistance to extinction than does continuous reinforcement. So, reinforcement is only given some of the time or at an inconsistent amount.
54
New cards
Delayed reinforcement
is a time delay between the desired response of an organism and the delivery of reward. An example would be when someone is on a diet, the reinforcement for the behavior (losing weight) will be delayed and occur at a later time, not immediately.
55
New cards
FIxed Ratio
reinforcement occurs after a set number of responses. Is predictable. (for every 10 As your child gets, he gets to pick out a new toy).
56
New cards
Variable Ratio
reinforcement is still based on the number of responses, however now it is unpredictable how many responses are needed to get the reinforcement. (for example, you may catch a fish after one catch, then after 5, then after 2).
57
New cards
Fixed interval
reinforcement is received after a set amount of time regardless of the number of responses during that time. (ex, every 30 mins someone walks by your desk and drops off a 5 dollar bill)
58
New cards
Variable interval
reinforcement is still based on the amount of time that has passed between responses, not the number of responses. Time that passes between reinforcement is unpredictable, leads to a slow, steady rate of responding. (Someone comes and drops a 5 dollar bill at random times).
59
New cards
Continuous Reinforcement.
Reinforcement follows every response. Praise after each action.
60
New cards
Primary Reinforcement
things that are in themselves rewarding (ex. Food)
61
New cards
secondary reinforcers
things that we have learned to value. (ex. Money, toys ect.)
62
New cards
Immediate reinforcement
If any reinforcer is presented immediately. Because the reinforcement is immediate, the person is more likely to repeat the action.
63
New cards
cognitive map
are mental pictures of spacial relationships between events. (like locating buildings, friends house, street).
64
New cards
Edward Tolman
is best-known for cognitive behaviorism, his research on cognitive maps, the theory of latent learning and the concept of an intervening variable.believed individuals do more than merely respond to stimuli; they act on beliefs, attitudes, changing conditions, and they strive toward goals. Is virtually the only behaviorists who found the stimulus-response theory unacceptable, because reinforcement was not necessary for learning to occur.
65
New cards
Latent learning
is learning that becomes obvious only once reinforcement is given for demonstrating it. For example, if you are going to school with a friend everyday and she drives, you will learn the way to school. But that learning only becomes obvious when you have to drive to school.
66
New cards
abstract learning
acquiring knowledge of general or intangible material, such as the meanings of concepts and propositions and the logical and systematic relations between them. Refers to the idea that we learn in general, we don't always learn about specific behaviors. We learn about concepts and categories. Another example of this can be found in pigeons. You can teach a pigeon to peck at pictures of chairs.
67
New cards
chaining
involves linking together previously conditioned behaviors. individual steps are recognized as requirements for task mastery. Breaks a task down into small steps and then teaches each step within the sequence by itself.
68
New cards
intrinsic motivation
is defined as the doing of an activity for its inherent satisfaction rather than for some separable consequence. A person is moved to act for the fun or challenge entailed rather than because of external products, pressures, or rewards.
69
New cards
extrinsic motivation
a motivation to participate in an activity based on meeting an external goal, garnering praise and approval, winning a competition, or receiving an award or payment.
70
New cards
mirror neurons
frontal lobe neurons that fire when preforming certain actions or when observing another doing so. Brain’s mirroring of another’s action may enable imitation and empathy.
71
New cards
Bandura’s Bobo Doll experiment
There are three groups. In the first children watch adults hitting, kicking, and hurting Bobo doll. The second group watched adults playing nicely with Bobo doll. Finally, the last group of children didn’t watch anything particularly kind or particularly violent. The point? Social learning. Children are more likely to imitate what they see and the children in the experiment did imitate the behavior on a Bobo doll based on what they watched.
72
New cards
Wolfgang Kohler
Insight learning is perhaps the greatest contribution he made to psychology. Building off the influence of gestalt psychology, he discovered that learning can occur when we gain insight into an entire situation, as opposed to focusing only on an individual part. he is probably best known for his empirical studies of chimpanzee problem solving
73
New cards
Token Economy
involves reinforcing good behavior by motivating someone with rewards for good grades or job performance(ex. friday jean day, access to extra food in prison ect.)
74
New cards
social learning
The idea that a child will imitate the behavior of those around them, both positive and negative). A child will socially learn from the behavior they watch.
75
New cards
modeling
learning by imitating others behaviors. It can lead to both positive and negative consequences.
76
New cards
learned helplessness
a condition in which repeated attempts to control a situation fail, resulting in a person believing that the situation is uncontrollable.
77
New cards
premack principle
explains that whichever of two activities is preferred can be used to reinforce the activity that is not preferred. For example, if peter likes apples, but does not like to practice for his piano lesson his mother could use apples to reinforce practicing piano.
