The purpose of this research was to investigate nonverbal communication through channel perception while observing any significant differences among race, sex, and social class background variables. In addition, differences and/or similarities in Afrocentric and Eurocentric world views in regard to nonverbal channel perception and cultural differences were studied. Rosenthal and his associates' (1979) Profile of Nonverbal Sensitivity test (PONS), representing eleven channels of nonverbal behavior, was administered to 172 American black college students (n=66) and white college students (n=106). The Belief Systems Analysis scale (BSA) by Myers was given to 105 of the 172 subjects; this scale determines the degree to which a person subscribes to a particular cultural world view. A three-way (race X sex X social class) multiple analysis of variance was performed on the eleven channels plus the total score for the PONS test. The data indicated a significant main effect due to the race variable and sex variable, for six and five channels respectively, along with the total scores. White college students scored higher than black students and females scored higher than males on these channels. Significant differences with the social class variable only occurred within one of the channels, and sex X social class interaction was indicated within another. A three-way (race X sex X social class) analysis of variance on the BSA scores indicated that black college students scored higher than white college students. No significant differences occurred between social classes; however a sex X social class interaction was indicated. Males from nonprofessional family backgrounds, and females from professional and nonprofessional backgrounds scored higher than males from professional family backgrounds. There were no significant differences between the sexes within the nonprofessional family background variable. (Author/GC)
