The aim of this study was to characterize exploration during discovering the affordance of gap-crossing and address individual differences in exploration. Most prior studies on affordances do not describe the process of how performing the action influences the perception of the affordance during trials. Although this process of exploration is not described in affordance literature, the need for exploration is recognized. In the current study exploration is defined as the systematic variation in perception and action to discover the affordance. A gap-crossing task was used to examine the perceptual judgment and performance of the task for ten trials of exploration. After these ten trials, a maximal gap-crossing ability test was performed as a measure of how accurate the affordance was discovered. We focused on patterns in trial-to-trial variation of perception and action and whether certain patterns of variation led to an accurate discovery of the maximal gap-crossing ability. The results showed individual differences in trial-to-trial variation in both the perception- and action variables. Secondly, not all participants discovered the maximal gap-crossing ability. Based on the patterns found, no specific strategy of exploration led to a more accurate discovery of the affordance. Altogether, practice performing the action facilitated the perception of the affordance of gap-crossing for some but not all. The processes of exploration differed across individuals as well as whether the affordance was discovered. Therefore in future studies, learning processes at the level of affordances need to be established.
