An experiment in which small lights are attached to the body of a person or an animal, which is then filmed moving in an otherwise completely dark environment, is known as the ______.
A)camouflage detection system
B)Corollary Discharge experiment
C)point-light walker display
D)light threshold detection system

Question

Quizplus · Accepted Answer

The experiment described in the question is the point-light walker display, in which small lights are attached to the body of a person or an animal and filmed moving in the dark. This technique is commonly used in studies of biological motion perception, as it allows researchers to manipulate the movement of the lights to investigate how the visual system interprets motion cues. A is incorrect because a camouflage detection system would involve detecting objects based on their visual similarity to the background. B is incorrect because a Corollary Discharge experiment involves testing the hypothesis that visual perception depends on signals from the motor system that enable the brain to predict the sensory consequences of self-generated movements. D is incorrect because a light threshold detection system would involve measuring the lowest level of light that can be detected by the visual system.
