Cross-modal mere exposure effects between visual and tactile modalities

Abstract
We investigated cross-modal mere exposure effects between the visual and tactile modalities using three dimensional novel objects. Participants were divided into four conditions including two experiment conditions (VT, TV) and two control conditions (V, T). In the VT condition, the participants were visually exposed to the target objects (exposure task), then 2 or 3 days later, they were asked to rate the preferences for the target objects mixed with distracter objects after touching them (rating task), and vice versa in the TV condition. The participants in the V or the T conditions were asked to rate preferences for all stimuli in either visual or tactile modalities. As a result, in the VT condition, it was found that participants significantly preferred the target objects to distracter ones. In contrast, in the TV condition, there were no significant differences in the preference ratings between the target and distracter objects, and those ratings were generally higher than the ratings in the V condition. In both of the control conditions, there are no significant differences in the preference ratings between the targets and distracters. These results suggested that cross-modal mere exposure effects occur depending on which modalities were used in the exposure and the rating tasks.
