The positive effect of contradictory information: The effect of verbal/nonverbal discrepancy on brand attitudes in the short term and the long term

While the field of verbal/nonverbal discrepancy has gained increasing interest in recent years, research in this
area related to the effect of discrepant communication on brand attitudes received considerably less attention. This
research uncovers a counterintuitive positive persuasive effect of contradictory information, showing that specifiable
conditions will be more favorably disposed to a brand attitude when verbal/nonverbal discrepancy is expressed than
an otherwise particular type of verbal/nonverbal congruency. This effect was revealed using an experimental design,
and was explored both in the short term and in the long term. Participants were exposed to a persuasive message
regarding a new brand product and were randomly assigned to four conditions: positive congruency (V+N+), negative
congruency (V-N-), leakage discrepancy (V+N-), and adaptive discrepancy (V-N+). The novel findings indicated
that adaptive discrepancy (V-N+), had the highest persuasive effect on brand attitudes in the long run. However,
leakage discrepancy (V+N-), had a negative effect on brand attitudes, particularly in the long run, eliminating the
sleeper effect. The present research expands the multimodal communication approach by presenting an analytical
and theoretical framework that delineates the complex persuasive effects of verbal/nonverbal interrelations. Finally,
the research develops reliance theory and developmental interactionist theory, regarding nonverbal primacy in persuasion.
