The influence of spatial pattern on visual short-term memory for contrast (2014)
Journal Article
Xing, Y., Ledgeway, T., McGraw, P. V., & Schluppeck, D. (2014). The influence of spatial pattern on visual short-term memory for contrast. Attention, Perception, and Psychophysics, 76(7), https://doi.org/10.3758/s13414-014-0671-x

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not dec... Read More about The influence of spatial pattern on visual short-term memory for contrast.

Decoding working memory of stimulus contrast in early visual cortex (2013)
Journal Article
Xing, Y., Ledgeway, T., McGraw, P. V., & Schluppeck, D. (2013). Decoding working memory of stimulus contrast in early visual cortex. Journal of Neuroscience, 33(25), https://doi.org/10.1523/JNEUROSCI.3754-12.2013

Most studies of the early stages of visual analysis (V1-V3) have focused on the properties of neurons that support processing of elemental features of a visual stimulus or scene, such as local contrast, orientation, or direction of motion. Recent evi... Read More about Decoding working memory of stimulus contrast in early visual cortex.

Luminance cues constrain chromatic blur discrimination in natural scene stimuli (2013)
Journal Article
Sharman, R. J., McGraw, P. V., & Peirce, J. W. (2013). Luminance cues constrain chromatic blur discrimination in natural scene stimuli. Journal of Vision, 13(4), Article 14. https://doi.org/10.1167/13.4.14

Introducing blur into the color components of a natural scene has very little effect on its percept, whereas blur introduced into the luminance component is very noticeable. Here we quantify the dominance of luminance information in blur detection an... Read More about Luminance cues constrain chromatic blur discrimination in natural scene stimuli.

The rapid emergence of stimulus specific perceptual learning (2012)
Journal Article
Hussain, Z., McGraw, P. V., Sekuler, A. B., & Bennett, P. J. (2012). The rapid emergence of stimulus specific perceptual learning. Frontiers in Psychology, 3(226), https://doi.org/10.3389/fpsyg.2012.00226

Is stimulus specific perceptual learning the result of extended practice or does it emerge early in the time course of learning? We examined this issue by manipulating the amount of practice given on a face identification task on Day 1, and altering...

Size-induced distortions in perceptual maps of visual space (2012)
Journal Article
McGraw, P. V., Roach, N. W., Badcock, D. R., & Whitaker, D. (2012). Size-induced distortions in perceptual maps of visual space. Journal of Vision, 12(4), https://doi.org/10.1167/12.4.8

In order to interact with our environment, the human brain constructs maps of visual space. The orderly mapping of external space across the retinal surface, termed retinotopy, is maintained at subsequent levels of visual cortical processing and unde...

Centrifugal propagation of motion adaptation effects across visual space (2008)
Journal Article
McGraw, P. V., & Roach, N. W. (2008). Centrifugal propagation of motion adaptation effects across visual space. Journal of Vision, 8(11), Article 11. https://doi.org/10.1167/8.11.1

Perceptual distortions induced by adaptation (aftereffects) arise through selective changes in the response properties of discrete subpopulations of neurons tuned to particular image features at the adapted spatial location. The systematic and well-d... Read More about Centrifugal propagation of motion adaptation effects across visual space.
