[HTML][HTML] Perception of animacy and direction from local biological motion signals

DHF Chang, NF Troje - Journal of Vision, 2008 - arvojournals.org
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

DHF Chang, NF Troje - Journal of Vision, 2009 - jov.arvojournals.org
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

DHF Chang, NF Troje - Journal of Vision, 2009 - iovs.arvojournals.org
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

DHF Chang, B Jiang, NHL Wong, JJ Wong, C Webster… - NeuroImage, 2021 - Elsevier
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

DHF Chang, H Ban, Y Ikegaya, I Fujita, NF Troje - NeuroImage, 2018 - Elsevier
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

HC Sun, AE Welchman, DHF Chang, M Di Luca - NeuroImage, 2016 - Elsevier
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

NF Troje, DHF Chang - Current Directions in Psychological …, 2023 - journals.sagepub.com
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 …
