Some of the most consistent findings about individual differences in implicit communication were related to sex differences. By far the largest number of findings that related implicit communications to individual differences were obtained by using characteristic preferences of physical distance. Since the major referents of implicit communication are positiveness, potency, and responsiveness, then characteristic differences in the tendency or ability to convey these attitudes are most relevant to the study of individual differences. Findings are also available on some characteristic tendencies in the implicit communications of more anxious and maladjusted subjects. Separate analyses of the slopes corresponding to communications of positive and negative attitudes yielded comparable effects for decoder sex and channel. A personality measure of positive interpersonal orientation, affiliative tendency, correlated with a factor consisting of various implicit indicators of positiveness. In sum, the ability or preference for communications of liking, dominance-submissiveness, or responsiveness can be related to personality attributes or other individual differences.
