To touch or not to touch: Examining the role of choice set size

Abstract Touch is a powerful means to explore one's environment and a critical sensory modality for information gathering. Previous research has shown the positive effects of product touch on key outcomes such as perceived product ownership and choice confidence, yet only in the context of consumers examining a solitary product or a small choice set. The current research draws on the choice overload hypothesis to examine whether a large choice set size attenuates the positive effects of touch. Our findings suggest that product touch results in more positive outcomes when choice sets are small (vs. large), with perceived choice difficulty mediating this effect (Experiment 1). The interactive effect of choice set size and touch is diminished in situations where touch conveys limited additional product information (Experiment 2). Further, we find that touching a large choice set can be advantageous among certain consumers, as those with a maximizing mindset respond more favorably to a large choice set when they can touch the items versus not (Experiment 3). We discuss research implications for the literatures on product touch, choice overload, and consumer mindsets, and practical implications for marketers as pertaining to assortment management, message framing, and online retail shopping environments.
