Abstract

We investigated whether perception of affordances for standing on an inclined surface depended on the height of center of mass of the perceiver-actor. Participants adjusted the angle of inclination of a surface until they felt that it was just barely possible for them to stand on that surface. They performed this task while wearing a backpack apparatus to which masses were attached in one of three configurations-high-mass, low-mass, and no-mass. Moreover, participants performed this task by viewing the inclined surface or by probing it with a hand-held rod (while blindfolded). Perception of affordances for standing on the inclined surface reflected the changes in center of mass brought on by the weighted backpack apparatus (the perceptual boundary occurred at a smaller angle of inclination in the high-mass condition than in the low-mass condition and in the no-mass condition). Moreover, perception of this affordance reflected such changes both when the surface was viewed and when the surface was probed with a hand-held rod (while blindfolded). The results highlight that perception of affordances is dynamic and task-dependent and suggest that the stimulation patterns that support perception of affordances are invariant and modality-independent.
