Visual attention in a complex search task differs between honeybees and bumblebees.
Mechanisms of spatial attention are used when the amount of gathered information exceeds processing capacity. Such mechanisms have been proposed in bees, but have not yet been experimentally demonstrated. We provide evidence that selective attention influences the foraging performance of two social bee species, the honeybee Apis mellifera and the bumblebee Bombus terrestris. Visual search tasks...
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 کاملFocal 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 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 کاملEditorial: Visual Search and Selective Attention
Visual search is one of the most successful paradigms employed in research on selective attention. In the prototypical search task, observers are presented with displays containing variable numbers of items one of which, the target, may differ from the other items, the distractors. Observers indicate, as rapidly and as accurately as possible, whether or not a target objects is present in the di...
