These findings suggest that the immediate effect of practice was mediated by the form of locomotion but not the resolution of the practice.Īdolph KE (1997) Learning in the development of infant locomotion. In contrast, no improvement was observed in any condition when using a wheelchair. Accuracy of perception of passability improved following both HR and LR practice when walking. When practicing passing through apertures, seven different aperture widths, including their minimum passable width (70 cm for both experiments) were presented around the affordance boundary with 1- or 5-cm increments for the HR or low-resolution (LR) conditions, respectively. Participants reported whether apertures of various widths were passable when walking while holding a 69-cm horizontal bar (Experiment 1) or when using a wheelchair (Experiment 2). The present study was designed to examine whether a critical factor in the immediate effect of such practice is the opportunity to detect very fine differences between possible and impossible behaviors. However, the immediate effect of such practice on the improvement of affordance perception is unclear. Perception of the fit between a person’s action capabilities and relevant environmental properties (i.e., affordances) is often fine tuned gradually through experience performing a behavior.
