Q

What is spontaneous recovery?

A

Reappearance of a learned response after its extinction

23
Q

What is stimulus generalization?

A

Responding similarly to stimuli which are similar to an already conditioned stimulus

24
Q

What is stimulus discrimination?

A

The learned ability to respond differently to similar stimuli

25
Q

What is a conditioned emotional response?

A

Emotional responses linked to previous nonemotional stimuli by classical conditioning
(A boy being scared of a dog once and thus being scared of dogs)

26
Q

What happens in the brain when a CER occurs?

A

The amygdala becomes more active, producing feelings of fear

27
Q

What is desensitization?

A

Gradually exposing a phobic person to feared stimuli while the person is relaxed

28
Q

What is vicarious classical conditioning?

A

Classical conditioning brought on by observing another person react to a stimulus

29
Q

What is the law of effect?

A

Responses that lead to desirable effects are repeated

Responses that lead to undesirable effects are not repeated

30
Q

What is an operant reinforcer?

A

Any event that reliably increases the probability or frequency of responses it follows

31
Q

What happens in operant conditioning?

A

Subjects learn to expect that a certain response will have a certain effect

32
Q

For rats in a Skinner box, minimal learning would occur if the delay between pressing the bar and receiving food past what time?

A

50 seconds

33
Q

What is response chaining?

A

Assembly of separate responses into a series of actions that lead to reinforcement

34
Q

What are superstitious behaviours?

A

Behaviours repeated because they seem to produce reinforcement, even though they are unnecessary

35
Q

What is shaping?

A

Gradually molding responses to a final desired pattern

36
Q

What is operant extinction?

A

Weakening or disappearance of nonreinforced operant responses

37
Q

What is positive reinforcement?

A

Reinforcement in which a response is followed by a reward or something similar

38
Q

What is negative reinforcement? (careful!)

A

Reinforcement in which a response is followed by an end to discomfort or something similar

39
Q

What is punishment?

A

Any event that follows a response and decreases its likelihood of it occurring again

40
Q

What is response cost?

A

Removal of a positive reinforcer after a response is made

41
Q

What are primary reinforcers?

A

Non-learned reinforcers that satisfy physiological needs

42
Q

What are secondary reinforcers?

A

Learned reinforcers that gain reinforcing properties by association with primary reinforcers

43
Q

What are token reinforcers?

A

Tangible secondary reinforcers. e.g. money

44
Q

What are social reinforcers?

A

Reinforcement based on receiving attention, approval, or affection from others

45
Q

What is feedback?

A

Information returned to a person about the effects a response had

46
Q

What three things make feedback most effective?

A

When it is:
Frequent
Immediate
Detailed

47
Q

What is programmed instruction?

A

Any learning format that presents information in small amounts, gives immediate practice, and continuous feedback

48
Q

What is partial reinforcement?

A

A pattern in which only a portion of all responses are reinforced

49
Q

What is the partial reinforcement effect?

A

Responses acquired with partial reinforcement are more resistant to extinction

50
Q

What is a fixed ratio schedule? How strong are the response rates it produces?

A

A set number of correct responses must be made to get a reinforcer.
Very high response rates

51
Q

What is variable ratio schedule? How strong are the response rates it produces?

A

A varied number of correct responses must be made to get a reinforcer (random).
High response rates

52
Q

What is a fixed interval schedule? How strong are the response rates it produces?

A

A reinforcer is given only when a correct response is made after a set amount of time has passed since the last reinforced response. Responses made during the time interval are not reinforced. (Rat on an FI-30-second schedule has to wait 30 seconds after the last reinforced response before pressing the bar will pay off)
Moderate response rates

53
Q

What is a variable interval schedule? How strong are the response rates it produces?

A

A reinforcer is given for the first correct response made after a varied amount of time has passed since the last reinforced response. Responses made during the time interval are not reinforced.
(Rat has to wait a varied amount of time before pressing the bar again will pay off)
Slow, steady response rates with tremendous resistance to extinction
