Visuals misleading consumers? Testing the visual superiority effect in advertising

Abstract

Purpose

The purpose of this study is to test the visual superiority effect in a verisimilar scenario that an industry association seeks to manipulate consumers using a visual element in its ad while providing an ostensibly balanced claim about the potential health effects of stevia.

Design/methodology/approach

Two experiments were conducted. In Study 1, an online experiment was conducted with a sample of 112 adult consumers using a two-group (headline frame type: gain vs loss), post-test only design with additional planned analysis of an individual difference (i.e. regulatory focus). In Study 2, another online experiment was implemented with a sample of 175 adults using a 2 (headline frame type: gain vs loss) × 2 (image valence: positive vs negative) between-subjects design with additional planned analysis of regulatory focus. The hypotheses were tested by running the PROCESS macro on SPSS.

Findings

The results showed that when exposed to the advertising message designed to elicit uncertainty, participants relied more on the visual than the textual content (i.e. framed headline and body text) in forming attitude toward the behavior (i.e. consuming stevia). Analysis of cognitive responses also revealed that those who received the stimulus ad with an image added (Study 2) generated significantly fewer thoughts related to the textual content of the ad than those who received the ad with no image (Study 1).

Originality/value

This study represents one of the earliest experimental inquiries into the visual superiority effect in an advertising context. While earlier studies have tended to rely on dual-processing models to test the effects of advertising stimuli featuring both textual and visual elements, the findings of this study (e.g. visual content overwhelmed its textual counterpart in producing persuasive effects) somewhat contradict the premise of dual-processing models.
