Dividing attention between auditory and visual perception
To what extent is simultaneous visual and auditory perception subject to capacity limitations and attentional control? TlIW experiments addressed this question by asking observers to recognize test tones and test letters under selective and divided attention. In Experiment I, both stimuli occurred on each trial, but subjects were cued in advance to process just one or both of the stimuli. In Ex...
متن کاملComparing Neural Correlates of Visual Target Detection in Serial Visual Presentations Having Different Temporal Correlations
Most visual stimuli we experience on a day-to-day basis are continuous sequences, with spatial structure highly correlated in time. During rapid serial visual presentation (RSVP), this correlation is absent. Here we study how subjects' target detection responses, both behavioral and electrophysiological, differ between continuous serial visual sequences (CSVP), flashed serial visual presentatio...
متن کاملInput control processes in rapid serial visual presentations: target selection and distractor inhibition.
The attentional blink refers to the finding that the 2nd of 2 targets embedded in a stream of rapidly presented distractors is often missed. Whereas most theories of the attentional blink focus on limited-capacity processes that occur after target selection, the present work investigates the selection process itself. Identifying a target letter caused an attentional blink for the enumeration of...
متن کاملDividing attention between two transparent motion surfaces results in a failure of selective attention.
In object-based attention, it is easier to divide attention between features within a single object than between features across objects. In this study we test the prediction of several capacity models in order to best characterize the cost to dividing attention between objects. Here we studied behavioral performance on a divided attention task in which subjects attended to the motion and lumin...
متن کاملErroneous selection of a non-target item improves subsequent target identification in rapid serial visual presentations
The second of two targets (T2) embedded in a rapid serial visual presentation (RSVSVP) is often missed even though the first (T1) is correctly reported (attentional blink). The rate of correct T2 identification is quite high, however, when T2 comes immediately after T1 (lag-1 sparing). This study investigated whether and how non-target items induce lag-1 sparing. One T1 and two T2s comprising l...
