Joint or separate? The effect of visual presentation on imagery and product evaluation

In this research, we examine the effect of joint versus separate visual presentation on consumers’ product evaluation. Counter to prior research on hedonic editing and unpacking, which suggests that separate presentation or unpacking produces greater utility, we propose and demonstrate in this paper that joint visual presentation can increase product evaluation. This pattern of effects occurs because presenting products together facilitates mental imagery of the product consumption, which leads to greater perceived psychological ownership and higher product evaluation. As such, the effect of joint presentation on product evaluation is attenuated when mental imagery is disrupted under joint presentation, encouraged under separate presentation, or when products lack complementarity to elicit mental imagery of one cohesive consumption episode. Evidence from seven studies provides converging support for these hypothesized effects and their underlying process. Our findings contribute to the literature on visual presentation, unpacking, and imagery, offering relevant implications to marketers and retailers.
