New Farnsworth-Munsell 100 hue test norms of normal observers for each year of age 5–22 and for age decades 30–70
Aims: To provide normative data for chromatic discrimination on the Farnsworth-Munsell 100 hue test particularly for observers under 23 years of age. Methods: Normal observers were screened forExpand

Increased sensitivity after repeated stimulation of residual spatial channels in blindsight
Lesions of the occipital cortex result in areas of cortical blindness affecting the corresponding regions of the patient's visual field. The traditional view is that, aside from some spontaneousExpand

Minimum presentation time for masked facial expression discrimination
Backward masking is a popular method of preventing awareness of facial expressions, but concerns have been expressed as to the effectiveness of masking in previous research, which may have resultedExpand

Previous studies have demonstrated that working memory for spatial location can be significantly disrupted by concurrent eye or limb movement (Baddeley, 1986; Smyth, Pearson, & Pendleton, 1988).Expand

Parameters affecting conscious versus unconscious visual discrimination with damage to the visual cortex (V1).
When the visual (striate) cortex (V1) is damaged in human subjects, cortical blindness results in the contralateral visual half field. Nevertheless, under some experimental conditions, subjectsExpand

Pattern of neuronal activity associated with conscious and unconscious processing of visual signals.
Following striate cortex damage in monkeys and humans there can be residual function mediated by parallel visual pathways. In humans this can sometimes be associated with a "feeling" that somethingExpand

Awareness of faces is modulated by their emotional meaning.
A central question in perception is how stimuli are selected for access to awareness. This study investigated the impact of emotional meaning on detection of faces using the attention blink paradigm.Expand

Intact navigation skills after bilateral loss of striate cortex
A patient with bilateral damage to primary visual (striated) cortex has provided the opportunity to assess just what visual capacities are possible in the absence of geniculo-striate pathways.Expand

Temporal properties of spatial channel of processing in hemianopia
The term blindsight, coined by Larry Weiskrantz, describes those discrimination abilities that can be elicited with visual stimuli restricted to the blindfield of a patient with occipital brainExpand

Spatial channels of visual processing in cortical blindness
Blindsight is the ability of some cortically blind patients to discriminate visual events presented within their field defect. We have examined a fundamental aspect of visual processing, namely theExpand
