Neural mechanisms of human perceptual choice under focused and divided attention.
Perceptual decisions occur after the evaluation and integration of momentary sensory inputs, and dividing attention between spatially disparate sources of information impairs decision performance. However, it remains unknown whether dividing attention degrades the precision of sensory signals, precludes their conversion into decision signals, or dampens the integration of decision information t...
متن کاملSeeing or hearing? Perceptual independence, modality confusions, and crossmodal congruity effects with focused and divided attention.
Observers were given brief presentations of pairs of simultaneous stimuli consisting of a visual and a spoken letter. In the visual focused-attention conditon, only the visual letter should be reported; in the auditory focused-attention condition, only the spoken letter should be reported; in the divided-attention condition, both letters, as well as their respective modalities, should be report...
متن کاملContextual Cueing under Divided Attention Spatial Context Learning Survives Interference from Working Memory Load Contextual Cueing under Divided Attention Contextual Cueing under Divided Attention
The human visual system is constantly confronted with an overwhelming amount of information, only a subset of which can be processed in complete detail. Attention and implicit learning are two important mechanisms that optimize vision. This study addresses the relationship between these two mechanisms. Specifically we ask: Is implicit learning of spatial context affected by the amount of workin...
متن کاملNeural correlates of auditory recognition under full and divided attention in younger and older adults.
We examined how aging affects the pattern of brain activity mediating retrieval under dual-task conditions. We used functional magnetic resonance imaging (fMRI) to measure brain activity in younger and older adults while they were engaged in an auditory verbal recognition test under either full or divided attention (FA or DA). During recognition under FA, older adults had more activity in bilat...
متن کاملGraphical displays: implications for divided attention, focused attention, and problem solving.
When completing tasks in complex, dynamic domains observers must consider the relationships among many variables (e.g., integrated tasks) as well as the values of individual variables (e.g., focused tasks). A critical issue in display design is whether or not a single display format can achieve the dual design goals of supporting performance at both types of tasks. We consider this issue from a...
