Q

What is spontaneous recovery in classical conditioning?

A

Spontaneous recovery is the return of a CR in a reduced form after a period when the CS is presented alone post-extinction.

Pavlov referred to this return as evidence that extinction suppresses the association rather than eliminates it.

Q

How did Pavlov’s dogs demonstrate stimulus discrimination?

A

The dogs learned to salivate only in response to a 2000-Hz tone and not to a 2100-Hz tone after discrimination training.

This involved presenting the 2000-Hz tone with meat powder and the 2100-Hz tone without it.

Q

What is a fixed interval (FI) schedule?

A

Reinforcement is provided after a fixed period of time, regardless of the number of responses during that interval.

Example: FI-20 schedule provides reinforcement every 20 seconds.

57
Q

What is a variable interval (VI) schedule?

A

Reinforcement is provided after intervals of varying and unpredictable lengths.

Example: VI-20 schedule averages reinforcement after 20 seconds but varies in length.

58

Reinforcement is provided after a variable number of responses.

Example: VR-10 schedule averages reinforcement after ten responses but varies.

60
Q

Which intermittent schedule produces the highest rate of responding?

A

Variable ratio (VR) schedule.

61
Q

Fill in the blank: An extinction burst refers to _______.

A

a temporary increase in behavior after reinforcement is withheld.

62
Q

True or False: A fixed interval schedule produces a high rate of responding.

A

False. FI schedules produce a low rate of responding.

63
Q

What happens to behavior when reinforcement is stopped in a continuous schedule?

A

It leads to rapid extinction of the behavior.

64
Q

What is thinning in the context of behavior reinforcement?

A

Thinning refers to reducing the amount of reinforcement for a behavior

Examples include switching from a continuous to an intermittent schedule of reinforcement or from an FR-10 to an FR-20 schedule.

65
Q

What is behavioral contrast?

A

Behavioral contrast occurs when the frequencies of two behaviors change due to an alteration in the rate of reinforcement for one of the behaviors

It can be negative (increased reinforcement for one behavior decreases the other) or positive (decreased reinforcement for one behavior increases the other).

66
Q

What is negative behavioral contrast?

A

Negative behavioral contrast occurs when the amount of reinforcement for Behavior A is increased while Behavior B remains unaltered, resulting in an increase in Behavior A and a decrease in Behavior B

This highlights the relationship between reinforcement rates and behavior frequencies.

67
Q

What is positive behavioral contrast?

A

Positive behavioral contrast occurs when the amount of reinforcement for Behavior A is decreased while Behavior B remains unaltered, resulting in a decrease in Behavior A and an increase in Behavior B

It emphasizes how changes in reinforcement for one behavior can affect another.

68
Q

What does the matching law state?

A

The matching law states that the rate of performing each behavior is proportional to the frequency of reinforcement when two or more behaviors are concurrently reinforced on different schedules

For example, a rat will press a lever more often if it is reinforced on a more frequent schedule.

69
Q

How does the magnitude of reinforcement relate to the matching law?

A

The rate of responding will match the magnitude of the reinforcement

For instance, if one lever provides access to food for a longer duration, it will be pressed more often.

70
Q

What are primary reinforcers?

A

Primary reinforcers are inherently reinforcing because they satisfy basic survival needs, such as food and water

They are essential for sustaining life.

71
Q

What are secondary reinforcers?

A

Secondary reinforcers are neutral stimuli that become reinforcing due to their association with primary reinforcers

Examples include praise and tokens.

72
Q

What are generalized reinforcers?

A

Generalized reinforcers are secondary reinforcers that are associated with a variety of primary reinforcers

Money is a common example as it can be exchanged for numerous goods and services.

73
Q

What is superstitious behavior?

A

Superstitious behavior occurs when a behavior increases due to accidental reinforcement

Skinner’s study with pigeons demonstrated this when they associated their actions with food delivery.

74
Q

Fill in the blank: In behavior reinforcement, _______ is when the amount of reinforcement is reduced.

A

thinning

75
Q

True or False: Positive behavioral contrast occurs when an increase in reinforcement for one behavior leads to an increase in another behavior.

A

False

Positive behavioral contrast refers to a decrease in reinforcement leading to an increase in another behavior.

76
Q

What is stimulus control?

A

A behavior is brought under stimulus control when it occurs in the presence of one stimulus but not another stimulus.

Example: Rats learn that pressing a lever delivers food when a light is blinking but not when it is not blinking.

77
Q

What is a positive discriminative stimulus (SD)?

A

A stimulus that signals reinforcement will be delivered.

Example: A blinking light indicating food delivery when a lever is pressed.

78
Q

What is a negative discriminative stimulus (S-delta)?

A

A stimulus that signals reinforcement will not be delivered.

Example: A non-blinking light indicating no food delivery when a lever is pressed.

79
Q

What is two-factor learning?

A

A combination of operant and classical conditioning that explains behavior performance in response to stimuli.

Performance is due to positive reinforcement and discrimination training.

80
Q

What are prompts in behavior conditioning?

A

Cues that help initiate the performance of a behavior, including cues, instructions, or physical guidance.

Example: ‘Finish your homework and you can play video games’.

81
Q

What is fading in the context of prompts?

A

The gradual removal of a prompt once the behavior is at the desired level.

82
Q

What is stimulus generalization?

A

When stimuli similar to the positive discriminative stimulus elicit the same response.

This concept is consistent in both operant and classical conditioning.

83
Q

What is response generalization?

A

When reinforcement for a specific behavior increases the likelihood of similar behaviors occurring.

Example: A child praised for sharing one toy starts sharing other toys.

84
Q

What is escape conditioning?

A

A behavior that occurs to escape an unpleasant stimulus.

Example: A dog jumps over a barrier to escape an electric shock.

85
Q

What is avoidance conditioning?

A

A behavior that occurs to avoid an unpleasant stimulus when a signal indicates it is about to occur.

Example: A dog jumps over a barrier to avoid an electric shock after seeing a blinking light.

86
Q

What is habituation?

A

The gradual decline in the frequency or magnitude of a response over time.

In operant conditioning, it explains why punishment becomes less effective long-term.

87
Q

True or False: Punishment tends to become more effective over time.

A

False

Punishment often becomes less effective due to habituation.

88
Q

What is the main goal of interventions based on classical conditioning?

A

To decrease or eliminate an undesirable behavior using extinction or counterconditioning.

89
Q

Name one type of intervention that uses extinction.

A

Exposure with response prevention.

90
Q

What are the two assumptions of exposure with response prevention?

A
  • Anxiety-arousing stimuli become conditioned stimuli due to previous pairing with an unconditioned stimulus.
  • The conditioned fear response does not extinguish because the person avoids the conditioned stimulus.

Q

In the context of exposure with response prevention, what does CS stand for?

A

Conditioned Stimulus.

92
Q

In the context of exposure with response prevention, what does US stand for?

96
Q

What is the difference between flooding and graded exposure?

A
  • Flooding involves sustained exposure to the most intense anxiety stimuli.
  • Graded exposure involves progressive exposure starting with the least anxiety-arousing stimulus.
97
Q

True or False: Graded exposure is more acceptable to clients who resist experiencing high levels of anxiety.

A

True.

98
Q

What is the importance of ending an exposure session?

A

It should not end until the client has experienced a substantial decrease in anxiety.

101
Q

What is one argument against the effectiveness of safety behaviors?

A

Patients may attribute the non-occurrence of anxiety to safety behaviors rather than to treatment.

102
Q

What is one argument in favor of safety behaviors during treatment?

A

They can make exposure less threatening and more tolerable to patients.
