Focal attention in visual search
Visual search operates in different modes assumed to reflect serial and parallel processing. The basis of this distinction is not yet clear. It is often assumed that serial search involves sequential shifts of focal attention across a scene and that no such shifts occur in parallel search. Direct measurements of attention effects during search show that the focus of attention moves to the targe...
متن کاملVisual search and selective attention
Visual search is a key paradigm in attention research that has proved to be a test bed for competing theories of selective attention. The starting point for most current theories of visual search has been Treisman’s ‘‘feature integration theory’’ of visual attention (e.g., Treisman & Gelade, 1980). A number of key issues that have been raised in attempts to test this theory are still pertinent ...
متن کاملAttention demands of visual search.
The relation between attention demand and the number of items in the array (array size) was investigated by engaging subjects in a primary search task and measuring spare capacity at different points in time, with a secondary tone task that occurred randomly on half of the trials. The major variables in both tasks were array size (4, 8, or 12 letters) and stimulus onset asynchrony (SOA: -400, -...
متن کاملRace Guides Attention in Visual Search.
It is known that faces are rapidly and even unconsciously categorized into social groups (black vs. white, male vs. female). Here, I test whether preferences for specific social groups guide attention, using a visual search paradigm. In Experiment 1 participants searched displays of neutral faces for an angry or frightened target face. Black target faces were detected more efficiently than whit...
متن کاملInvestigating attention in complex visual search
How we attend to and search for objects in the real world is influenced by a host of low-level and higher-level factors whose interactions are poorly understood. The vast majority of studies approach this issue by experimentally controlling one or two factors in isolation, often under conditions with limited ecological validity. We present a comprehensive regression framework, together with a m...
