IntroductionWhat effect emerges when confronting a persuasion message that contains a verbal versus nonverbal discrepancy on brand attitude? This theoretical and practical question is approached from a multimodal communication perspective that focuses on the interaction of verbal and nonverbal patterns on brand attitude. This research contributes by presenting an analytical and theoretical framework that conceptualizes the interaction between verbal and nonverbal modalities and shows the positive effect of particular patterns of verbal and nonverbal discrepancy on brand attitude. The current research explains the influence of various patterns of verbal and nonverbal discrepancy/ congruency and delineates the multimodal communication effect on brand attitudes in both the short term and the long term. Finally, this research presents a complex theoretical account that bridges the effect of discrepant information and the sleeper effect on brand attitude and contributes to reliance theory of verbal versus nonverbal primacy.
Multimodal communication approachThe theoretical framework of this study draws on a multimodal communication approach that emphasizes the importance of examining the mutual relations between verbal and nonverbal modes of communication [1]. Verbal and nonverbal communications are present in face-to-face interactions in a way that constitutes an integrative event. Addressees receive verbal message accompanied by nonverbal messages, and the way in which the overall message is perceived is determined by the relationship between the two modes [2].Recently, research into the relationship between verbal and nonverbal communication has advanced as new and more complex approaches have been introduced [3]. A current trend is to carry out integrative research that recognizes the need to assess the interconnections of verbal and nonverbal communication [4]. This examination explains the ways in which vocal and visible behaviors are associated with one another, and explores the interrelationships between different modalities of communication [5]. The present research argues that a combined examination of verbal and nonverbal communication and the relationship between them can provide new insights into the study of persuasion and brand attitudes.The relationship between verbal and nonverbal modes of communication is conceptualized based on the distinction between two types of links: congruency and discrepancy [6]. The link of congruency is when there is a relationship of identity or similarity between the messages: the overall message is coherent, and the verbal and nonverbal messages are mutually enhancing. Congruent communication is associated with certainty, an unequivocal message [7]. A theoretical perspective in game theory has suggested that communication patterns characterized by "sending accuracy" that are, the exactness with which an individual communicates messages is associated with congruence behavior [8]. Congruency presents a message that is certain, consistent, and clear. Consequently, it is asso...
