The effect of the invasion of personal space upon an individual's subsequent use of personal space was investigated. Subjects in the invasion condition stood closer to the confederate than did subjects in the non-invasion condition. Results were interpreted in terms of the confederate serving as a model for the subjects. Still, subjects generally did not stand as close as the intimate distances exhibited by the confederates. Also, females initially stood closer to the confederates than did males. Both of these findings support other research regarding the norms for interpersonal distance. Seated distance measures were not significant in the present study. (Author)
