Texture segmentation without human V4 (2017)
Journal Article
Norman, L., Heywood, C., & Kentridge, R. (2017). Texture segmentation without human V4. Visual Cognition, 25(1-3), 184-195. https://doi.org/10.1080/13506285.2017.1301612

Texture segmentation, or second-order segmentation, is a rapid perceptual process, allowing object and surface boundaries to be effortlessly detected. It is currently unclear whether this is achieved in early cortical areas or whether it necessitates... Read More about Texture segmentation without human V4.

Direct encoding of orientation variance in the visual system (2015)
Journal Article
Norman, L., Heywood, C., & Kentridge, R. (2015). Direct encoding of orientation variance in the visual system. Journal of Vision, 15(4), 1-14. https://doi.org/10.1167/15.4.3

Our perception of regional irregularity, an example of which is orientation variance, seems effortless when we view two patches of texture that differ in this attribute. Little is understood, however, of how the visual system encodes a regional stati... Read More about Direct encoding of orientation variance in the visual system.

Exogenous attention to unseen objects? (2015)
Journal Article
Norman, L., Heywood, C., & Kentridge, R. (2015). Exogenous attention to unseen objects?. Consciousness and Cognition, 35, 319-329. https://doi.org/10.1016/j.concog.2015.02.015

Attention and awareness are closely related phenomena, but recent evidence has shown that not all attended stimuli give rise to awareness. Controversy still remains over whether, and the extent to which, a dissociation between attention and awareness... Read More about Exogenous attention to unseen objects?.

Colour constancy for an unseen surface (2014)
Journal Article
Norman, L., Akins, K., Heywood, C., & Kentridge, R. (2014). Colour constancy for an unseen surface. Current Biology, 24(23), 2822-2826. https://doi.org/10.1016/j.cub.2014.10.009

The illumination of a scene strongly affects our perception of objects in that scene, e.g., the pages of a book illuminated by candlelight will appear quite yellow relative to other types of artificial illuminants. Yet at the same time, the reader st... Read More about Colour constancy for an unseen surface.

Object-based attention without awareness (2013)
Journal Article
Norman, L. J., Heywood, C. A., & Kentridge, R. W. (2013). Object-based attention without awareness. Psychological Science, 24(6), 836-843. https://doi.org/10.1177/0956797612461449

Attention and awareness are often considered to be related. Some forms of attention can, however, facilitate the processing of stimuli that remain unseen. It is unclear whether this dissociation extends beyond selection on the basis of primitive prop... Read More about Object-based attention without awareness.
