Perceptual Set Within the "Attentional Blink"

Perception. 2019. Vol. 48. P. 26-26.
Makarov I., Gorbunova E. S.

The experiment involved dual-target rapid serial visual presentation task in which 15 stimuli were displayed within each trial. The time of presentation for one stimulus was 90 milliseconds; interstimulus interval was 10 milliseconds. Shape and size of stimuli were varied. Targets could have two, one, or no shared features. There were three colors: green for distractors, yellow for first target stimulus, and blue for second target stimulus. The second target was presented on five different lags after first target. Participants task was to detect both targets on each trial. Repeated measures analysis of variance revealed the significant impact of the lag factor and the number of shared features factor. Attentional blink was observed only for no shared features condition. The perceptual set created by the first target reduces the interference in working memory and prevents the second target omission for the conditions with one and two shared features.
