Biological Motion Alters Coherent Motion Perception
Perception, 2008When a movie presents a person walking, the background appears to move in the direction opposite to the person's gait. This study verified this backscroll illusion by presenting a point-light walker against a background of a random-dot cinematogram (RDC).

Perception of Biological Motion
Perception, 1997Boundary conditions for perception of biological motion were explored with the use of computer-generated point-light animation sequences. Perception of this unique form of structure from motion is immune to variations in dot contrast polarity, dot disparity, and spatial-frequency filtering.

Motion Induction from Biological Motion
Perception, 2003A new type of motion illusion is described in which ambiguous motion becomes unidirectional on superimposition of a human figure walking on a treadmill. A point-light walker in profile was superimposed on a vertical counterphase grating backdrop. Eleven naïve observers judged the apparent direction of motion against the grating as left or right in a ...

Perception of Elliptic Biological Motion
Perception, 2006We tested the ability of the mature visual system for discrimination between types of elliptic biological motion on the basis of event kinematics. Healthy adult volunteers were presented with point-light displays depicting elliptic motion when only a single dot, a moving point-light arm, or a whole point-light human figure was visible.

The Thatcher Effect in Biological Motion
Perception, 2011We demonstrate the Thatcher effect in biological-motion displays and show that it is primarily a result of the moving, and not static, cues in the display.

Specificity of regions processing biological motion
European Journal of Neuroscience, 2005AbstractUsing functional magnetic resonance imaging and point light displays portraying six different human actions, we were able to show that several visual cortical regions, including human MT/V5 complex, posterior inferior temporal gyrus and superior temporal sulcus, are differentially active in the subtraction comparing biological motion to ...

2002
The paper discusses the detailed analysis of visual speech. As with other forms of biological motion, humans are known to be very sensitive to the realism in the ways the lips move. In order to determine the elements that come to play in the perceptual analysis of visual speech, it is important to have control over the data.

Cats Perceive Biological Motion
Psychological Science, 1993With behavioral techniques, cats were trained to discriminate a point-light animation sequence depicting biological motion (i.e., a cat walking) from an animation sequence consisting of equivalent local motion vectors lacking the global synchrony present in the biological-motion sequence (i.e., “foil” displays). Successful discrimination was evidenced
