Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used a series masking experiments that defy explanation by feed-forward theories. The occurs when brief display target plus mask is continued with alone. Two processes were found: an early process affected physical factors such adapting luminance and later attentional set size. called object substitution, because it whenever there mismatch visual...

Can four dots that surround, but do not touch, a target shape act as mask to reduce discriminability? Although existing theories of metacontrast and pattern masking say “no,” we report this occurs when targets appear in unpredictable locations. In three experiments, four-dot was compared with standard surrounded the target. accuracy predictably different for two masks at central display location Experiment I, both had similar strong effects on parafoveal 2 revealed were insensitive contour...
According to predictions from the Weak Central Coherence (WCC) theory for perceptual processing, persons with autism should display a tendency focus on minute details rather than more general picture (Frith & Happé, 1994). However, evidence this is not consistent findings of an enhanced detection local targets (Plaisted, O'Riordan, Baron-Cohen, 1998b; Plaisted, Swettenham, Rees, 1999), but typical global bias (Mottron, Burack, Stauder, Robaey, 1999; Ozonoff, Strayer, McMahon, Filloux,...
The task of visual search is to determine as rapidly possible whether a target item present or absent in display. Rapidly detected items are thought contain features that correspond primitive elements the human system. In previous theories, it has been assumed based on simple two-dimensional image. However, also access another level representation, one describes properties corresponding three-dimensional scene. Among these three dimensionality and direction lighting, but not viewing...
A recent study demonstrated that observers' ability to identify targets in a rapid visual sequence was enhanced when they simultaneously listened happy music. In the reported here, we examined how emotion-attention relationship is influenced by changes both mood valence (negative vs. positive) and arousal (low high). We used standard induction procedure generate calm, happy, sad, anxious moods participants. Results for an attentional blink task showed no differences first-target accuracy,...
It has generally been assumed that rapid visual search is based on simple features and spatial relations between are irrelevant for this task. Seven experiments involving line drawings contradict assumption; a major determinant of the presence junctions. Arrow- Y-junctions were detected rapidly in isolation when they embedded rectangular polyhedra. Search T-junctions was considerably slower. Drawings containing often gave rise to very slow even distinguishing arrow- or present. This...
A new method is presented for performing rapid and accurate numerical estimation. The derived from an area of human cognitive psychology called preattentive processing. Preattentive processing refers to initial organization the visual field based on operations believed be rapid, automatic, spatially parallel. Examples features that can detected in this way include hue, intensity, orientation, size, motion. We beleive studies vision should used assist design visualization tools, especially...
We present a new method for using texture and color to visualize multivariate data elements arranged on an underlying height field. combine simple patterns with perceptually uniform colors increase the number of attribute values we can display simultaneously. Our technique builds multicolored perceptual (or pexels) represent each element. Attribute encoded in element are used vary appearance its pexel. Texture that form when pexels displayed be rapidly accurately explore dataset. built by...
Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments.Segments easily detected in isolation were difficult to detect when embedded a configuration, indicating preemption by low-level groups.This preemption-which caused stimulus components become inaccessible rapid search-was an all-ornothing effect, and so could serve as powerful test of grouping.It shown these effects unlikely be due blurring...
Abstract Background Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found varying degrees the general population. To measure these traits facilitate their use research, several questionnaires have been developed that provide broad measures of autistic [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since development, our understanding has grown considerably, it is arguable existing do not...
Interactions with natural environments and nature-related stimuli have been found to be beneficial cognitive performance, in particular on executive tasks high demands directed attention processes. However, results vary across different studies. The aim of the present paper was evaluate effects nature vs. urban performance all our published new/unpublished studies testing interactions urban/built control environments, an executive-functioning test attention-the backwards digit span (BDS)...
Driver inattention is thought to cause many automobile crashes. However, the research on attention fragmented, and applied driving further split between three largely independent traditions: experimental research, differential crash rate automation research. The goal of this review provide a conceptual framework unify research—a based combination two fundamental dimensions attentional selection: selection with without conscious awareness (controlled automatic), by innate acquired cognitive...
