Attended but unseen: Visual attention is not sufficient for visual awareness (2007)

Does any one psychological process give rise to visual awareness? One candidate is selective attention—when we attend to something it seems we always see it. But if attention can selectively enhance our response to an unseen stimulus then attention c... Read More about Attended but unseen: Visual attention is not sufficient for visual awareness.

Q-cgi: new techniques to assess variation in perception applied to facial attractiveness (2007)
Journal Article

We present novel methods for assessing variation in the perception of subjective cues based on a fusion of Q-methodology with computer graphics techniques. Participants first Q-sort face stimuli based upon a subjective quality; a randomization-based...

Object onset and parvocellular guidance of attentional allocation (2005)
Journal Article

The parvocellular visual pathway in the primate brain is known to be involved with the processing of color. However, a subject of debate is whether an abrupt change in color, conveyed via this pathway, is capable of automatically attracting attention...

Covert processing of visual form in the absence of area LO (2004)
Journal Article

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.

Visual salience in the change detection paradigm: The special role of object onset (2004)
Journal Article

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...

Attentional capture by colour and motion in cerebral achromatopsia (2003)
Journal Article

Cerebral achromatopsia is a rare condition in which damage to the ventromedial occipital area of the cortex results in the loss of colour experience. Nevertheless, cortically colour-blind patients can still use wavelength variation to perceive form a... Read More about Attentional capture by colour and motion in cerebral achromatopsia.

Detectability of onsets versus offsets in the change detection paradigm (2003)

The human visual system is particularly sensitive to abrupt onset of new objects that appear in the visual field. Onsets have been shown to capture attention even when other transients simultaneously occur. This has led some authors to argue for the...
