Cats perceive biological motion

Article Abstract:

The ability of cats to perceive and discriminate biologic motion was examined. The perception of animate motion from a few point light vectors was tested by assessing the cat's discrimination of computer-generated point light animation sequences that depict biologic motion and asynchronous segments. Results showed that cats could analyze the kinematic data in point light biological motion. Perception was achieved through a oriented hierarchy based on the movement of body parts and joint connections.

The informational basis of motion coherence

Article Abstract:

Information theory can predict the goodness of perceived patterns if a judgement task has implicit underlying distributions of pattern alternatives. The evidence shows that the coherence matches occur based upon Shannon-Weiner information entropy. While evaluating the various coherence perception models, the fact that humans do not discriminate direction of movement with arbitrarily fine resolution was kept in view.

Perceptual priming by invisible motion

Article Abstract:

A study was conducted to show that robust priming can be determined by motion implied by context and by motion that occurs outside of visual awareness. Results indicated that context can influence motion perception when a moving object is visible throughout the duration of an event. Findings also showed evidence for robust priming by hidden motion implied by the overall context of the event.
