Construct: Attention

RDoC Classification

Domain: Cognitive Systems

Description

Attention refers to a range of processes that regulate access to capacity-limited systems, such as awareness, higher perceptual processes, and motor action. The concepts of capacity limitation and competition are inherent to the concepts of selective and divided attention.

Behavior

ANT task distractibility Attentional lapses vs sustained attention Distractibility Object/feature attention Psychophysics Spatial attention

Paradigms

attentional blink and psychological refractory period paradigm blocked channel-selection tasks dichotic listening distraction paradigms (capture) Dual Task Paradigms inter-modal selective attention spatial and non-spatial cuing paradigms, time-series of response times to extract variability and frequency domain analyses visual search

Target detection tasks in the absence of competition are considered measues of sustained attention, and not selective or divided attention, which are subsumed under cog control
