Does product touch affect consumer attitude toward a product? Meta-analysis of effect sizes, moderators, and mediators

Consumers rely on physical touch in offline shopping and vicarious touch (i.e., imagining touch) in online shopping to develop their attitudes toward a product. The subject of how touching (versus not touching) affects consumer attitudes toward a product merits studying. However, past research has drawn controversial conclusions regarding the effect of product touch on consumer attitudes. This study conducted a meta-analysis to resolve this inconsistency and explore the reasons for this inconsistency. It quantitatively analyzed 185 effect sizes in 42 empirical studies conducted between 2003 and 2022. In general, relative to not touching, touching had a positive effect on consumers' attitudes toward a product (rho $\rho $ = 0.242, p < 0.001), and the effect size was moderate. Furthermore, the positive touch effect was mediated by consumers' cognitive experiences relating to the product and their affective experiences relating to the product. The cognitive path (total indirect effect = 0.068, p < 0.001) being stronger than the affective path (total indirect effect = 0.067, p < 0.001). Importantly, it showed that past inconsistency regarding the touch effect could be explained by moderators including product type (utilitarian versus hedonic), participants' uncertainty avoidance, and type of touch (physical touch versus vicarious touch). This study provides new insights into the product touch literature and offers valuable implications for online and offline retailing and consumer well-being.
