Visual perception depends not only on local stimulus features but also on their relationship to the surrounding stimulus context, as evident in both local and contextual influences on figure-ground segmentation. Intermediate visual areas may play a r... Read More about Preserved local but disrupted contextual figure-ground influences in an individual with abnormal function of intermediate visual areas.

Cue Competition Affects Temporal Dynamics of Edge-assignment in Human Visual Cortex (2011)
Journal Article
Brooks. (2011). Cue Competition Affects Temporal Dynamics of Edge-assignment in Human Visual Cortex. Journal of Cognitive Neuroscience, 631 - 644. https://doi.org/10.1162/jocn.2010.21433

Edge-assignment determines the perception of relative depth across an edge and the shape of the closer side. Many cues determine edge-assignment, but relatively little is known about the neural mechanisms involved in combining these cues. Here, we ma...

Grouping puts figure-ground assignment in context by constraining propagation of edge assignment (2010)
Journal Article
Brooks. (2010). Grouping puts figure-ground assignment in context by constraining propagation of edge assignment. Attention, Perception, and Psychophysics, 1431- 1431. https://doi.org/10.3758/APP.72.5.1431

Figure-ground organization involves the assignment of edges to a figural shape on one or the other side of each dividing edge. Established visual cues for edge assignment primarily concern relatively local rather than contextual factors. In the prese...

Multivariate decoding of EEG data reveals similar mechanisms mediate perceptual adaptation and spontaneous perceptual reversals
Presentation / Conference
Dundas, K., & Brooks, J. Multivariate decoding of EEG data reveals similar mechanisms mediate perceptual adaptation and spontaneous perceptual reversals. Presented at ECVP 2021

The cause of spontaneous perceptual reversals of visually ambiguous stimuli (e.g., Rubin’s faces-vase) has been attributed to several different mechanisms. One hypothesis suggests that adaptation, or “neural fatigue”, builds up while one interpretati...
