Influence of inter-item symmetry in visual search.
Does visual search involve a serial inspection of individual items (Feature Integration Theory) or are items grouped and segregated prior to their consideration as a possible target (Attentional Engagement Theory)? For search items defined by motion and shape there is strong support for prior grouping (Kingstone and Bischof, 1999). The present study tested for grouping based on inter-item shape...
متن کاملOn the Role of Symmetry in Visual Search
// is known that the efficiency oj visual search for a target item among distractor items increases when distractors are similar to each other and decreases nhen target and distractors are similar. Here we show that symmetry relations between targets and distractors can alter search efficiency. When distractors form a background texture symmetrical about a vertical axis, search is easier than w...
متن کاملLie symmetry analysis for Kawahara-KdV equations
We introduce a new solution for Kawahara-KdV equations. The Lie group analysis is used to carry out the integration of this equations. The similarity reductions and exact solutions are obtained based on the optimal system method.
متن کاملAttentional set interacts with perceptual load in visual search.
In the present study, we examined the hypothesis that perceptual load is the primary factor that determines the efficiency of attentional selection. Participants performed a visual search task under conditions of high- and low-load. In line with the perceptual load hypothesis, presenting conditions of high- and low-load in separate blocks of trials resulted in processing of to-be-ignored stimul...
