[HTML][HTML] Perception of animacy and direction from local biological motion signals
We present three experiments that investigated the perception of animacy and direction from
local biological motion cues. Coherent and scrambled point-light displays of humans, cats, …

[HTML][HTML] Acceleration carries the local inversion effect in biological motion perception
The ability to derive the facing direction of a spatially scrambled point-light walker relies on
the motions of the feet and is impaired if they are inverted. We exploited this local inversion …

[PDF][PDF] Training transfers the limits on perception from parietal to ventral cortex
DHF Chang, C Mevorach, Z Kourtzi, AE Welchman - Current Biology, 2014 - cell.com
Visually guided behavior depends on (1) extracting and (2) discriminating signals from complex
retinal inputs, and these perceptual skills improve with practice [1]. For instance, training …

[HTML][HTML] Characterizing global and local mechanisms in biological motion perception
The perception of biological motion is subserved by both a global process that retrieves
structural information and a local process that is sensitive to individual limb motions. Here, we …

[HTML][HTML] The human posterior cingulate and the stress-response benefits of viewing green urban landscapes
The mechanistic and neural bases of why green environments drive positive mental health
outcomes remain poorly understood. We show that viewing green urban landscapes that vary …

Cortical and subcortical responses to biological motion
Using fMRI and multivariate analyses we sought to understand the neural representations of
articulated body shape and local kinematics in biological motion. We show that in addition …

[HTML][HTML] Look but don't touch: Visual cues to surface structure drive somatosensory cortex
When planning interactions with nearby objects, our brain uses visual information to estimate
shape, material composition, and surface structure before we come into contact with them. …

Body configuration modulates the usage of local cues to direction in biological-motion perception
M Hirai, DHF Chang, DR Saunders… - Psychological …, 2011 - journals.sagepub.com
The presence of information in a visual display does not guarantee its use by the visual
system. Studies of inversion effects in both face recognition and biological-motion perception …

Life detection from biological motion
Life motion, the active movements of people and other animals, contains a wealth of information
that is potentially accessible to the visual system of an observer. Biological-motion point-…

[HTML][HTML] Attentional advantages in video-game experts are not related to perceptual tendencies
NHL Wong, DHF Chang - Scientific reports, 2018 - nature.com
Previous studies have suggested that extensive action video gaming may enhance perceptual
and attentional capacities. Here, we probed whether attentional differences between …
