Abstract: | When a series of three successive to-be-reported items (targets) is displayed in a rapid serial visual presentation (RSVP)
stream of distractors, it has been shown that no attentional blink—a marked impairment in the report of the second of two
targets, typically observed when the targets appear within 200–600 ms of one another—occurs in target accuracy. The present
study examines three recently introduced computational models that provide different explanations of this protracted sparing
effect. Using a standard RSVP design and these models, we provide empirical data and simulations that illustrate that structural
limitations affect the processing of successive targets. In addition, we compare the candidate mechanisms that might underlie
these limitations. |
