Thirty-six subjects were administered the 16PF and participated in a brief, unstructured interview. Paralinguistic behavior (fluency, duration and speech rate) were scored from tapes of the interviews and correlated to personality characteristics. Four significant relationships emerged revealing that fluency is related to adventurousness; duration is related to maturity and superego strength; and speech rate is related to surgency. The relationship between personality and nonverbal behaviors is discussed with reference to diagnosis and communication in counseling-like interviews. (Author)
