A bogus postcard technique was used to study the effects of touch and
vocal intensity on the compliance of 248 male and female subjects with
a simple request. Subjects in three American cities were approached b
y three female confederates and were asked to mail a postcard. A touch
to the forearm accompanied half of the requests, while vocal intensit
y was varied as either soft, medium, or loud. Comparisons were made fo
r rates of total compliance, initial noncompliance, and subsequent non
compliance. Contrary to expectations, vocal intensity, rather than tou
ch, affected compliance. Results are interpreted in terms of arousal-r
eduction, involvement, and status-attribution views of the non-verbal
communication and compliance-gaining effect.
