Abstract Details

Humans can perceive affordances both for themselves and for others, and perception of affordances is a function of perceptual-motor experience that may result, for example, from playing a sport. Enhanced perceptual sensitivity resulting from sport experience may indicate a type of perceptual learning via attunement. Athletes have been shown to be more accurate at perceiving a sport-relevant action-scaled affordance for another person when compared to non-athletes, but are no better at perceiving sport-relevant and sport-irrelevant body-scaled affordances for another. The current study investigated the informational basis for this enhanced perceptual ability by evaluating whether kinematics inform perceivers about action-scaled, but not body-scaled, affordances for others, and whether athletic experience enhances sensitivity to kinematic information. Perceptual reports of basketball players for an action-scaled (reach-with-jump) affordance, but not body-scaled (standing-reach and sit) affordances, improved with exposure to kinematic information, while non-basketball players did not improve in any affordance reports after exposure to kinematic information. This indicates non-athletes may be less experienced in extracting relevant information from walking kinematics that specifies another person’s action capabilities. These results suggest action-scaled affordances may be specified by kinematic information to which athletes are already attuned by virtue of their sport experience.
