Psychology chapter 5

Learning is any relatively permanent change in behavior brought about by experience or practice
Ivan Pavlov
A Russian physiologist (a person who studied the workings of the body) (1849 - 1936) who pioneered the empirical study of the basic principles of a particular kind of learning. He studied the digestive system in his dogs, he built a device that would accurately measure the amount of saliva produced by the dogs when they were fed a measured amount of food
Classical conditioning
Learning to make an involuntary (reflex) response to a stimulus other than the original, natural stimulus that normally produces the reflex
An involuntary response, one that is not under personal control or choice
Unconditioned ("unlearned) stimulus (UCS)
A naturally occurring stimulus that leads to an involuntary (reflex) response
Unconditioned response (UCR)
An involuntary (reflex) response to a naturally occurring or unconditioned stimulus
Neutral stimulus (NS)
Stimulus that has no effect on the desired response
Conditioned stimulus (CS)
Stimulus that becomes able to produce a learned reflex response by being paired with the original unconditioned stimulus
Conditioned Stimulus
The CS must come before the UCS and they must come very close together in time. The CS is always followed by a conditioned response.
Conditioned means learned
Response (CR)
Learned reflex response to a conditioned stimulus
The repeated pairing of the NS and the UCS (unconditioned stimulus)
Stimulus generalization
The tendency to respond to a stimulus that is only similar to the original conditioned stimulus with the conditioned response
Stimulus discrimination
The tendency to stop making a generalized response to a stimulus that is similar to the original conditioned stimulus because the similar stimulus is never paired with the unconditioned stimulus
The disappearance or weakening of a learned response following the removal or absence of the unconditioned stimulus (in classical conditioning) or the removal of a reinforcer (in operant conditioning)
Spontaneous recovery
The reappearance of a learned response after extinction has occurred
Higher-order conditioning
Occurs when a strong conditioned stimulus is paired with a neutral stimulus, causing the neutral stimulus to become a second conditioned stimulus
Conditional emotional response
Emotional response that has become classically conditioned to occur to learned stimuli, such as a fear of dogs or the emotional reaction that occurs when seeing an attractive person
Conditioned taste aversion
Development of a nausea or aversion response to a particular taste because that taste was followed by a nausea reaction, ocurring after only one association
Biological preparedness
Referring to the tendency of animals to learn certain associations, such as taste and nausea, with only one or few pairings due to the survival value of the learning
Stimulus substitution
Original theory in which Pavlov stated that classical conditioning occurred because the conditioned stimulus became a substitute for the unconditioned stimulus by being paired closely together
Cognitive perspective
Modern theory in which the classical conditioning is seen to occur because the conditioned stimulus provides the information or an expectancy about the coming of the unconditioned stimulus
Operant conditioning
The learning of voluntary behavior through the effects of pleasant and unpleasant consequences to responses
Edward Thorndike
(1874-1919) was one of the first researcher to explore and attempt to outline the laws of learning voluntary responses, although the field was not yet called operant conditioning
Law of Effect
Law stating that if an action is followed by a pleasurable consequence, it will tend to be repeated, and it followed by an unpleasant consequence, it will tend not to be repeated
B.F. Skinner
(1904 - 1990) was the behaviorist who assumed leadership of the field after John Watson. He was even more determined than Watson that psychologists should study only measurable, observable behavior
Any behavior that is voluntary
Any event or stimulus, that when following a response, increases the probability that the response will occur again
Primary reinforcers
Any reinforcer that is naturally reinforcing by meeting a basic biological needs, such as hunger, thirst, or touch
Secondary reinforcers
Any reinforcer that becomes reinforcing after being paired with a primary reinforcer, such as praise, tokens, or gold stars
Positive Reinforcement
The reinforcement of a response by the addition or experiencing of a pleasurable stimulus
Negative reinforcement
The reinforcement of a response by the removal, escape from, or avoidance of an unpleasant stimulus
Continuous reinforcement
The reinforcement of each and every correct response
Partial reinforcement
Occurs when a reinforcer is given after some, but not all, of the correct responses
Partial reinforcement effect
The tendency for a response that is reinforced after some, but not all, correct responses to be very resistant to extinction
Schedule of reinforcement
Schedules of reinforcement are the precise rules that are used to present (or to remove) reinforcers (or punishers) following a specified operant behavior. These rules are defined in terms of the time and/or the number of responses required in order to present (or to remove) a reinforcer (or a punisher). Different schedules schedules of reinforcement produce distinctive effects on operant behavior.
Fixed ratio
Schedule of reinforcement in which the number of responses required for reinforcement is always the same
Variable ratio
Schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is different for each trial or event
Fixed interval
Schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is always the same
Variable interval
Schedule of reinforcement in which the interval of time that must pass before reinforcement becomes possible is different for each trail or event
Any event or object that, when following a response, makes that response less likely to happen again
Punishment by application
The punishment of a response by the addition or experiencing of an unpleasant stimulus
Punishment by removal
The punishment of a response by the removal of a pleasurable stimulus
The reinforcement of simple steps in behavior that lead to a desired, more complex behavior
Successive approximations
Small steps in behavior, one after the other, that lead to a particular goal behavior
The removal of a reinforcer to reduce the frequency of a behavior
Spontaneous recovery
(in classical conditioning, the recurrence of a conditioned response after extinction) will also happen with operant responses
Discriminative stimulus
Any stimulus, such as a stop sign or a doorknob, that provides the organism with a cue for making a certain response in order to obtain reinforcement
Instinctive drift
Tendency for an animal's behavior to revert to genetically controlled patterns
Behavior modification
The use of operant conditioning techniques to bring about desired changes in behavior
Token economy
Type of behavior modification in which desired behavior is rewarded with tokens
Time-out is a form of mild punishment by removal in which a misbehaving animal, child, or adult is placed in a special area away from the attention of others. Essentially, the organism is being "removed" from any possibility of positive reinforcement in the form of attention.
Applied behavior analysis (ABA)
Modern term for a form of functional analysis and behavior modification that uses a variety of behavioral techniques to mold a desired behavior or response
Using feedback about biological condiitons to bring involuntary responses, such as blood pressure and relaxation, under voluntary control
Form of biofeedback using brain-scanning devices to provide feedback about brain activity in an effort to modify behavior
Cognitive learning
Thoughts, feelings, and expectations that clearly existed in the mind and that seemed to influence observable behavior and eventually began to develop a cognitive learning theory to supplement the more traditional theories of learning
Edward Tolman
Gestalt psychologist, he did an experiment teaching three groups of rats the same maze, once at a time. This experiment was to test latent learning.
Latent learning
Learning that remains hidden until its application becomes useful
Martin Seligman
Famous for founding the field of positive psychology, a new way of looking at the entire concept of mental health and therapy. He and his colleagues discovered an unexpected phenomenon from doing classical conditioning experiments on dogs.
Learned helplessness
The tendency to fail to act to escape from a situation because of a history of repeated failures in the past
Wolfgang Kohler
A gestalt psychologist who studied animal learning. He set up a problem for one of the chimpanzees, the chimp was faced with the problem of how to get to a banana that was placed out of his reach and the chimp pushed one stick out of the cage as far as it would go toward the banana and then pushed the other stick behind the first one. This was a form of insight.
Insight learning
The sudden perception of relationship among various parts of a problem, allowing the solution to the problem to come quickly
Observational learning
Learning new behavior by watching a model perform that behavior
Learning/performance distinction
Referring to the observation that learning can take place without actual performance of the learned behavior
Albert Bandura
He did a classic study with the Booboo doll. the doll was used to demonstrate the impact of observing an adult model performing aggressive behavior on the later aggressive behavior of children. The children imitated the adult model's behavior when they believed they were alone and not being watched
