1
New cards
classical conditioning
the subject learns to give a response it already knows to a new stimulus.
2
New cards
Response
is a reaction to a stimulus.
3
New cards
Neutral stimulus (NS)
initially does not elicit a response.
4
New cards
Unconditioned stimulus (UCS or US)
reflexively, or automatically, brings about the unconditioned response (UCR or UR).
5
New cards
Conditioned stimulus (CS)
is a NS at first, but when paired with the UCS, it elicits the conditioned response (CR).
6
New cards
Aversive conditioning
Conditioning involving an unpleasant or harmful unconditioned stimulus or reinforcer, such as this conditioning of Baby Albert.
7
New cards
Spontaneous recovery
Although not fully understood by behaviorists, sometimes the extinguished response will show up again later without the re-pairing of the UCS and CS.
8
New cards
Generalization
occurs when stimuli similar to the CS also elicit the CR without any training.
9
New cards
Discrimination
occurs when only the CS produces the CR.
10
New cards
Stimulus
is a change in the environment that elicits (brings about) a response.
11
New cards
Higher-Order Conditioning
Higher-order conditioning, also called second-order or secondary conditioning, occurs when a well-learned CS is paired with an NS to produce a CR to the NS.
12
New cards
Operant Conditioning
In operant conditioning, an active subject voluntarily emits behaviors and can learn new behaviors.
13
New cards
Instrumental learning
is a type of learning that involves the acquisition and use of skills or strategies to achieve a specific goal. It can involve trial-and-error processes, imitation, reinforcement, modeling, memorization and more.
14
New cards
Law of Effect
states that behaviors followed by satisfying or positive consequences are strengthened (more likely to occur), while behaviors followed by annoying or negative consequences are weakened (less likely to occur).
15
New cards
Positive reinforcement
or reward training, emission of a behavior or response is followed by a reinforcer that increases the probability that the response will occur again.
16
New cards
Premack principle
a more probable behavior can be used as a reinforcer for a less probable one.
17
New cards
Negative reinforcement
takes away an aversive or unpleasant consequence after a behavior has been given.
18
New cards
Punishment training
a learner’s response is followed by an aversive consequence.
19
New cards
Omission training
In this training procedure, a response by the learner is followed by taking away something of value from the learner.
20
New cards
Aversive conditioning
is a type of learning in which an organism learns to associate an unpleasant stimulus with a particular behavior.
21
New cards
Avoidance behavior
takes away the aversive stimulus before it begins.
22
New cards
Secondary reinforcer
is something neutral that, when associated with a primary reinforcer, becomes rewarding.
23
New cards
Generalized reinforcer
is a secondary reinforcer that can be associated with a number of different primary reinforcers.
24
New cards
Token economy
has been used extensively in institutions such as mental hospitals and jails.
25
New cards
Primary reinforcer
is something that is biologically important and, thus, rewarding.
26
New cards
Shaping
positively reinforcing closer and closer approximations of the desired behavior, is an effective way of teaching a new behavior.
27
New cards
Chaining
is used to establish a specific sequence of behaviors by initially positively reinforcing each behavior in a desired sequence and then later rewarding only the completed sequence.
28
New cards
Partial reinforcement
schedules based on the number of desired responses are ratio schedules.
29
New cards
Interval schedules
Schedules based on time.
30
New cards
Fixed ratio
schedules reinforce the desired behavior after a specific number of responses have been made.
31
New cards
Fixed interval
schedules reinforce the first desired response made after a specific length of time.
32
New cards
Variable ratio
schedule, the number of responses needed before reinforcement occurs changes at random around an average.
33
New cards
Variable interval
schedule, the amount of time that elapses before reinforcement of the behavior changes.
34
New cards
Continuous reinforcement
is the schedule that provides reinforcement every time the behavior is exhibited by the organism.
35
New cards
Robert Rescorla
suggesting a contingency model of classical conditioning that the CS tells the organism that the US will follow.
36
New cards
Insight
is the sudden appearance of an answer or solution to a problem.
37
New cards
Latent Learning
is defined as learning in the absence of rewards.
38
New cards
Social Learning
which occurs by watching the behavior of a model.
39
New cards
Conditioned taste aversion
an intense dislike and avoidance of a food because of its association with an unpleasant or painful stimulus through backward conditioning.
40
New cards
Instinctive drift
a conditioned response that drifts back toward the natural (instinctive) behavior of the organism
41
New cards
Preparedness
means that through evolution, animals are biologically predisposed to easily learn behaviors related to their survival as a species, and that behaviors contrary to an animal’s natural tendencies are learned slowly or not at all.
