Chromatic edges, surfaces and constancies in cerebral achromatopsia. (2004)
Journal Article
Kentridge, R., Heywood, C., & Cowey, A. (2004). Chromatic edges, surfaces and constancies in cerebral achromatopsia. Neuropsychologia, 42(6), 821-830. https://doi.org/10.1016/j.neuropsychologia.2003.11.002

We tested achromatopsic observer, MS, on a number of tasks to establish the extent to which he can process chromatic contour. Stimuli, specified in terms of cone-contrast, were presented in a three-choice oddity paradigm. First we show that MS is abl...

Visual salience in the change detection paradigm: The special role of object onset (2004)
Journal Article
Cole, G., Kentridge, R., & Heywood, C. (2004). Visual salience in the change detection paradigm: The special role of object onset. Journal of Experimental Psychology: Human Perception and Performance, 30(3), 464-477. https://doi.org/10.1037/0096-1523.30.3.464

The relative efficacy with which appearance of a new object orients visual attention was investigated. At issue is whether the visual system treats onset as being of particular importance or only 1 of a number of stimulus events equally likely to sum...

Covert processing of visual form in the absence of area LO (2004)
Journal Article
Kentridge, R., Heywood, C., & Milner, A. (2004). Covert processing of visual form in the absence of area LO. Neuropsychologia, 42(11), 1488-1495. https://doi.org/10.1016/j.neuropsychologia.2004.03.007

The patient D.F., who suffers from severe visual form agnosia, has been found to have a bilateral lesion of area LO, an area known to be intimately involved in the perception of object shape. Despite her perceptual impairment, however, D.F. retains r... Read More about Covert processing of visual form in the absence of area LO.

Spatial attention speeds discrimination without awareness in blindsight. (2004)
Journal Article
Kentridge, R. W., Heywood, C. A., & Weiskrantz, L. (2004). Spatial attention speeds discrimination without awareness in blindsight. Neuropsychologia, 42(6), 831-835. https://doi.org/10.1016/j.neuropsychologia.2003.11.001

An intimate relationship is often assumed between visual attention and visual awareness. Using a subject, patient GY, with the neurological condition of ‘blindsight’ we show that although attention may be a necessary precursor to visual awareness it...
