Spatial cuing in a stereoscopic display : Evidence for a “ depth - aware ” attentional focus
524 The degree to which visual information is processed largely depends on the amount of attention allocated to that information. A number of metaphors have been used to describe the spatial allocation of visual attention. One of the earliest metaphors for attention was a spotlight (Broadbent, 1982; Posner, Snyder, & Davidson, 1980; Shulman, Remington, & McLean, 1979). The spotlight view depict...
متن کاملSpatial cuing in a stereoscopic display: attention remains "depth-aware" with age.
Previous research has demonstrated that spatial attention is "depth-aware": Reaction times (RT) are greater for shifts in depth and two-dimensional (2-D) space than in 2-D space alone. This experiment examined whether the ability to focus attention at a depth location is maintained with advanced age. Twelve younger and 12 older observers viewed stereoscopic displays in which one of four spatial...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Luminance spatial scale facilitates stereoscopic depth segmentation.
Are differences in luminance spatial frequency between surfaces that overlap in depth useful for surface segmentation? We examined this question, using a novel stimulus termed a dual-surface disparity grating. The dual-surface grating was made from Gabor micropatterns and consisted of two superimposed sinusoidal disparity gratings of identical disparity-modulation spatial frequency and orientat...
متن کاملAttentional modulation of visual processing in adult dyslexia: a spatial-cuing deficit.
Anumber of researchers have suggested that deficient visual attention may play a causal role in dyslexia. However, traditional methods for investigating this assertion have been limited by the conflation of sensory and attentional factors and the inability to isolate large attentional effects. In this study, we sought to overcome these problems by combining spatial cuing with a visual search ta...
