5
Q
_______________ is defined as the recovery of a response to a stimulus after habituation has occurred.
A
Dishabituation
6
Q
_______________ is the recovery of a response to a stimulus, usually after a different stimulus has been presented.
A

7
Q
_________________ is the creation of a pairing, or association, either between two stimuli or between a behaviour and a response.
A
Associative learning
8
Q
There are two types of associative learning: ________________ and ________________.
A
- Classical conditioning
- Operant conditioning
9
Q
_________________ is a type of associative learning that takes advantage of biological, instinctual responses to create associations between two unrelated stimuli.
A
Classical conditioning
10
Q
Any stimulus that brings about such a reflexive response is called an _________________.
A
Unconditioned stimulus
11
Q
Any stimulus that brings about such an innate or reflexive response is called an ________________.
A
Unconditioned response
12
Q
Many stimuli do not produce a reflexive response and are known as ________________.
A
Neutral stimuli
13
Q
Ivan Pavlov turned a neutral stimulus into a ________________: a normally neutral stimulus that, through association, now causes a reflexive response called a __________________.
A
- Conditioned stimulus
- Conditioned response
14
Q
The process of using a reflexive, unconditioned stimulus to turn a neutral stimulus into a conditioned stimulus is termed ________________.
A
Acquisition
15
Q
______________ refers to the loss of a conditioned response, and can occur if the conditioned stimulus is repeatedly presented without the unconditioned stimulus.
A
Extinction
16
Q
The extinction of a response is not always permanent; after some time, presenting subjects again with an extinct conditioned stimulus will sometimes produce a weak conditioned response, a phenomenon called __________________.
A
Spontaneous recovery
17
Q
_______________ is a broadening effect by which a stimulus similar enough to the conditioned stimulus can also produce the conditioned response.
A
Generalization
18
Q
In __________________ (sometimes referred to as just ________________), an organism learns to distinguish between similar stimuli.

19
Q
The study of _________________ examines the ways in which consequences of voluntary behaviours change the frequency of those behaviours.

Operant conditioning
20
Q
Operant conditioning is associated with B. F. Skinner, who is considered one of the founders of ________________, the theory that all behaviours are conditioned.
A
Behaviourism
21
Q
_______________ is the process of increasing the likelihood that an animal will perform a behaviour.
A
Reinforcement
22
Q
________________ increase the frequency of a behaviour by adding a positive consequence or incentive following the desire behaviour.
A
Positive reinforcers
23
Q
_______________ act similarly in that they increase the frequency of a behaviour, but they do so by removing something unpleasant.
A
Negative reinforcers
24
Q
______________ describes a situation where the animal experiences the unpleasant stimulus and, in response, displays the desired behaviour in order to trigger the removal of the stimulus.
A
Escape learning
25
______________ occurs when the animal displays the desired behaviour in anticipation of the unpleasant stimulus, thereby avoiding the unpleasant stimulus.
Avoidance learning
26
The meat can be said to be a ________________ because the meat is a treat that the dog responds to naturally.
Primary reinforcer
27
The dog may even associate the presence of the trainer with the possibility of reward, making the presence of the trainer a __________________.
Discriminative stimulus
28
In contrast to reinforcement, ______________ uses conditioning to reduce the occurrence of a behaviour.
Punishment
29
________________ adds an unpleasant consequence ion response to a behaviour to reduce that behaviour; for example, receiving a ticket and having to pay a fine for parking illegally.
Positive punishment
30
Because positive punishment involves using something unpleasant too discourage a behaviour, it is sometimes referred to as ________________.
Aversive conditioning
31
________________ is removing a stimulus in order to cause reduction of a behaviour.
Negative punishment
32
A parent or guardian may forbid a child from watching television as a consequence for bad behaviour, with the goal of preventing the behaviour from happening again. This is an example of _________________.

_________________ is the removal of a bothersome stimulus to encourage a behaviour.
Negative punishment
34
________________ is the addition of a bothersome stimulus to reduce a behaviour.

Reinforcement schedule
36
____________ (_____) ____________ reinforce a behaviour after a specific number of performances of that behaviour.
Fixed-ratio (FR) schedules
37
In a typical operant conditioning experiment, researchers might reward a rat with a food pellet every their time it presses a bar in its cage. This is an example of ___________________.
Fixed-ratio schedule
38

41
_______________ (______) _____________ reinforce the first instance of a behaviour after a specified time period has elapsed.
Fixed-interval (FI) schedules
42
Once the rat gets a pellet, it has to wait 60 seconds before it gets another pellet. The first lever press after 60 seconds gets a pellet, but subsequent presses during those 60 seconds accomplish nothing. This is an example of _____________________.
Fixed-interval schedule
43
_______________ (_____) _____________ reinforce a behaviour the first time that behaviour is performed after a varying interval of time.
Variable-interval (VI) schedules
44
Instead of waiting exactly 60 seconds, our rat might have to wait 90 seconds, then 30 seconds, then three minutes. In each case, once the interval elapses, the next press gets the rat a pellet. This is an example of ________________.
Variable-interval schedule
45

Autobiographical memory
86
_____________ is the name given to the process of demonstrating that something that has been learned has been retained.

Semantic network
92
When one node of our semantic network is activated, such as seeing the word red on a sign, the other linked concepts around it are also unconsciously activated, a process known as __________________.
Spreading activation
93
Spreading activation is at the heart of the previously mentioned positive priming, as recall is aided by first being presented with a word or phrase, a _____________, that is close to the desired semantic memory.
Recall cue
94
Another common retrieval cue is _______________, where memory is aided by being in the physical location where encoding took place.

Misinformation effect
121
_______________ refers to false memories that have included a false detail into a particular memory.
