A study of the relationship between individual differences in nonverbal expressiveness and factors of personality and social interaction

Some theoretical and applied implications of individual differences in nonverbal expressiveness were investigated in a medical setting. In Study I, the abilities of 21 physicians to express different emotions through voice tone were assessed and related to physician personality and to actual patient ratings of the physician. Study II replicated Study I using visual as well as vocal cues (i.e., videotapes) of a new sample of physicians, and added a study of physician greetings. It was found that: (1) Aspects of expressive ability were reliably correlated with a cluster of personality traits, thus supporting the notion that nonverbal affective style may be a window to inner dispositions; and (2) expressive ability was related to patient satisfaction with the interpersonal manner of their physicians and to the judged likeability of the physician's greeting, thus providing evidence for the importance of this ability for social interaction.
