Question

Quizplus · Accepted Answer

When the point-light walker is viewed in a dark room while moving, an observer would perceive a person. The lights on different body locations give the impression of movement, which the observer can perceive as a person walking. However, if the point-light walker is not moving, the observer may not perceive a person, and if just one light on the person is moving, it may not be sufficient to give the impression of a person walking. Additionally, the observer may not perceive the point-light walker as a human if the lights are not in the shape of a typical human body.
