Q

A

Q

John B. Watson

A

Q

Robert Rescorles

A

said that classical conditioning was more than a simple learned association between 2 stimuli, the conditioned stimulus must be a reliable signal that predicts the presence of the unconditioned response (tested rats and tones)

Q

taste aversion

A

exception to general principles of classical conditioning, a classically conditioned dislike for food after becoming ill from the food, violates classical conditioning because learning occurs after 1 pairing and the UCR occurs hours after the presence of the neutral stimulus

Q

John Garcia

A

produced taste aversions in rats in controlled lab conditions, discovered that rats are more likely to associate a painful stimulus with external stimuli and a taste stimulus with internal stimuli

25
biological preparedness
organisms are predisposed to associate certain stimuli with certain responses, an association not biologically prepared occurs with great difficulty, taste aversions are very biologically prepared
26
phobia
an extreme, irrational fear of a specific object/situation, Martin Seligman saw that phobias were selective (not all traumatic events become phobias), humans are more likely to fear ancient threats to their evolutionary ancestors (fear module)
27
Edward L. Thorndike
investigated animal learning of voluntary behaviors based on their consequences, tested that cats used trial and error to escape a puzzle box (not human reasoning)
28
law of effect
reponses that lead to satisfaction become strengthened while responses that lead to unpleasantries become weakened (less likely to occur again)
29
B.F. Skinner
behaviorist, searched for a lawful process to explain the order in behavior (classically conditioning is limited to reflexive behaviors)
30
operant
an active behavior that operates on the environment to generate a consequence
31
operant conditioning
changing the probability that a response will repeat by manipulating the consequences
32
reinforcement
a stimulus/event that occurs after the operant and increases the likelihood that the operant will repeat
33
positive reinforcement
a reinforcing stimulus is added after the operant (something is added), what constitutes a reinforcing stimulus differs from person to person
34
negative reinforcement
the operant if followed by the removal or avoidance of an aversive stimulus (something is subtracted)
35
primary reinforcer
is naturally reinforcing (food, water, warmth, sex, etc.)
36
conditioned reinforcers (secondary reinforcers)
acquired by association with a primary reinforcer (money, awards, etc.)
37
punishment
a behavior followed by an aversive consequence which decreases the likelihood that the operant will repeat
38
positive punishment
a response is followed by the addition of an aversive stimulus
39
negative punishment
a response is followed by the loss of a reinforcing stimulus
40
alternatives to punishment
reinforcing an alternate behavior, extinguishing the problem behavior, reinforcing the non-occurrence of the problem behavior, time-out from all positive reinforcement
41
Premack principle
a preferred activity can be used to reinforce a less preferred activity
42
discriminative stimuli
a specific stimulus that is more likely to reinforce a particular operant (eg phone ringing often leads to picking up the phone)
43
operant chamber (Skinner box)
a small cage with a food dispenser automatically records the number of operants performed by the experimental animal
44
shaping
reinforce successively closer approximations of behavior until the correct behavior is displayed
45
continuous reinforcement
the most efficient way to strengthen a response is to immediately reinforce every occurrence of the operant
46
partial reinforcement
responses are only reinforced sometimes (like in real life)
47
extinction
when a learned response is no longer reinforced, the likelihood of repetition gradually declines
48
partial reinforcement effect
partially reinforced behavior is more resistant to extinction than continuously reinforced behavior
49
schedules of reinforcement
specific preset arrangements of partial reinforcement result in different response rates
50
fixed-ratio schedule
reinforcement is presented after a fixed number of responses, produces increased response rates in burst-pause patterns
51
variable-ratio schedule
reinforcement is presented after an average number of responses but varies
52
fixed-interval schedule
reinforcement is presented after the 1st response in a preset time interval, responses increase as the time interval comes near
53
variable-interval schedule
reinforcement is presented after the 1st response in an average length time interval, moderate/steady rates of response
54
behavioral modification
the application of operant conditioning learning principles to help develop adaptive behaviors
55
Edward C. Tolman
believed that cognitive processes were important to learning complex behaviors (tested rats in mazes)
56
cognitive map
term by Tolman, a mental representation of a (mazes) layout built through experience, can be used to make an alternative route when the usual is blocked
57
latent learning
term by Tolman, learning is not immediately demonstrated in overt behavior, learning is the acquisition of knowledge not just changes in behavior
58
Martin Seligman
said that during cognitive conditioning, animals can develop a cognitive expectation that their behavior doesn't affect their environment
59
learned helplessness
Seligman term, exposure to an inescapable aversive event will result in passive behavior, the 1st step to overcoming is to create a sense of control
60
instinctive drift
Brelandterm, natural behaviors interfere with operant behaviors, biologically predispositions to perform natural behaviors are strong enough to overcome a lack of reinforcement (reinforcement is not the sole determinant of behavior)
61
observational learning
most human learning, learning by observing others actions
62
Albert Bandura
pioneer of observational learning believed that the process used actively judgemental and constructive cognitive processes, tested groups of kids watching aggressive Bobo doll behavior
