When she was a baby, Racine had intense reactions to stimuli, cried often, and was easily frightened. Racine's behavior as a baby best reflects which aspect of Buss and Plomin's (1984) model of temperament?

A. sociability

B. emotionality

C. activity

D. reactivity

B. emotionality

Explanation:

Emotionality refers to a child's emotional reactions to environmental stimuli. In other words, a child who is highly emotional may cry easily, be more fearful, get excited quickly, or exhibit other strong emotional responses. A child low on this temperament may seem more easy going, relaxed, and less interested in his or her surroundings. As an adult, high emotionality may be related to artistic endeavors, relationships, and career choice.
