A lens-mapping framework for understanding the encoding and decoding of interpersonal dispositions in nonverbal behavior.

Abstract

Recent reviewers have concluded that dispositions are not very reliably encoded in nonverbal behavior, although observers seem eager to use nonverbal information to decode the dispositions of others. A modified Brunswik lens model (E. Brunswik, 1956) and behavior mapping were used to examine the encoding and decoding of 8 interpersonal dispositions from nonverbal cues. First, 20 triads completed self-assessments and were videotaped during conversation. Next, 38 of their nonverbal behaviors were independently scored. Finally, 21 unacquainted peers rated all 60 conversers on the same dispositions. Across the 8 dispositions, encoding multiple correlations ranged from 0 to.62 and decoding ranged from .74 to .82. Achievement (self-other correlations) ranged from .18 to .45. Some implications of the results for interpersonal conflict and personality assessment are discussed.
