An experiment was conducted to study the relationship between cognitive dis
sonance and helping behavior. A counterattitudinal procedure was employed t
o arouse dissonance. For half of the participants, an experimental confeder
ate entered the room and elicited an opportunity for them to offer help. in
this situation, fewer subjects in the dissonance condition offered help th
an subjects in the no-dissonance condition. The least helping occurred amon
g dissonance subjects with the highest level of commitment to the counterat
titudinal task. Those with a medium level of commitment offered significant
ly more help. Despite the fact that results in line with Festinger's cognit
ive dissonance theory (subjects' attitudinal change) were obtained in the n
o-helping situation, in helping situations, dissonance subjects who offered
help presented significantly less attitude change than those who did not o
ffer it. This was considered to be a result of helpfulness reducing dissona
nce arousal.
