Multisensory interaction in product choice: grasping a product affects choice of other seen products

Consumers often touch products before reaching purchase decisions, and indeed touch improves evaluations of the given product. The present research investigates how touching a given product influences perception and choice of other seen products. We show that grasping a source product increases the visual fluency of a haptically similar product, thereby increasing the likelihood of choosing that product, but not the willingness to pay for it (Study 1). We also show that visually crowded rather than sparse product displays increase the effect of touch on choosing other haptically similar products, and that individuals' instrumental need for touch further modulates this effect (Study 2). Our results suggest that by manipulating or mimicking the haptic features (e.g., shape and size) of objects that consumers grasp while shopping, marketers can develop packaging that facilitates consumers' visual processing of their products, thereby increasing choice of those products.
