Perception of limited-lifetime biological motion from different viewpoints.
Studies with time-limited point-lights suggested that biological motion does not require local motion detection. These studies used walkers seen from the side, but biological motion perception excels also when walkers are oriented toward the observer, or in intermediate, half-profile views. In perspective projection, the local motion of points on the body provides a cue to the 3D structure of t...
متن کاملResidual motion perception in a "motion-blind" patient, assessed with limited-lifetime random dot stimuli.
A neurological patient (L.M.) suffering a specific loss of visual motion perception (Zihl et al., 1983) due to extrastriate cortical damage was studied using random dot "limited-lifetime" stimuli with a direction discrimination task. With a stimulus like that of Newsome and Pare (1988), the patient exhibited a severe deficit for motion perception, only being able to perform well for very high v...
متن کاملCreating stimuli for the study of biological-motion perception.
In the perception of biological motion, the stimulus information is confined to a small number of lights attached to the major joints of a moving person. Despite this drastic degradation of the stimulus information, the human visual apparatus organizes the swarm of moving dots into a vivid percept of a moving biological creature. Several techniques have been proposed to create point-light stimu...
متن کاملCrowding of biological motion stimuli.
It is difficult to identify a target in the peripheral visual field when it is flanked by distractors. In the present study, we investigated this "crowding" effect for biological motion stimuli. Three walking biological motion stimuli were presented horizontally in the periphery with various distances between them, and observers reported the walking direction of the central figure. When the int...
متن کاملBiological motion perception from sequential position information
Introduction Both in generating human activity and in the visual perception of it, the brain is confronted with the many degrees of freedom involved in the movement of body and limbs. Not unlikely, the perception of motor actions is supported by mechanisms that are very similar to those in control of these actions. Hints towards an interaction between perceptual and action processes can be foun...
