Can we correctly perceive the reaching range of others?
Little is known about our ability to predict the motor capacities of other people. This study explored how observers perceive the reaching range of another person by asking them to judge the reachability of a moving object. Experiments 1 and 2 found that observers overestimated the reaching ranges of both short and tall people. Estimates were larger when objects moved towards rather than away from the person. Experiment 3 showed that perceived reaching range depended on the observer's viewing perspective. Compared with previous findings, these results suggest that observers use different cognitive operations to mentally simulate actions for themselves vs. others. They also inform the current debate about motor imagery and action understanding.
