The interaction between perceptual grouping and attention

摘要: I investigated the interaction between perceptual grouping and attention, focusing specifically on distracter rejection. The novelty of thesis lies in study different configural types their effect search across space time. Grouping by configuration is likely to facilitate making rejection easier. can be based regular locations elements, similarity elements whether form a closed shape. effects occurred under conditions which groups never contained target, although detection was faster if target fell internal group relative when it outside group. These results, together with those from neuropsychological studies reported here, are consistent rapid suppression irrelevant distractor groups. Primitive grouping, apparently clusters similar proximal took place even attention reduced patients chronic spatial biases visual selection. However, neurological damage attention-related brain regions did disrupt dependent element Attention may, therefore, more critical for some forms grouping. interacts determine performance.
