Q

Whenever her family drove to visit her grandmother, they had to cross a rickety, old bridge in the countryside. Her father, in a misguided attempt at humor, made a major production out of these crossings. He would stop short of the bridge and carry on about the great danger. Obviously, he thought the bridge was safe or he wouldn’t have driven across it. However, the naïve young girl was terrified by her father’s scare tactics.

27

A

Stimulus generalization

The more similar new stimuli are to the original CS, the greater the likelihood of generalization.

31
Q

______ —the reinforcement of closer and closer approximations of a desired response.

A

shaping

32
Q

34
Q

49

50
Q

_______ To learn through observation, you must pay attention to another person’s behavior and its consequences.

Attention

51

A

Reproduction.

53
Q

These neurons are located in the frontal and parietal lobes of the cerebral cortex and fire both when an individual performs an action and when that individual observes someone else performing that action.

They may also play a role in the experience of _____ emotions, or emotions felt as a result of another individual’s experience, such as empathy.

A

mirror neurons

vicarious emotions,

54
