Abstract
Running head: Central and sensory processing in dual-tasks Key words: psychological refractory period; attentional blink; dual-task; attention; consciousness; magnetoencephalography 1 Central and sensory processing in dual-tasks Doing two things at once is difficult. When two tasks have to be performed within a short interval, the second is sharply delayed, an effect called the Psychological Refractory Period (PRP). Similarly, when two successive visual targets are briefly flashed, people may fail to detect the second target (Attentional Blink or AB). Although AB and PRP are typically studied in very different paradigms, a recent detailed neuromimetic model suggests that both might arise from the same serial stage during which stimuli gain access to consciousness and, as a result, can be arbitrarily routed to any other appropriate processor. Here, in agreement with this model, we demonstrate that AB and PRP can be obtained on alternate trials of the hal-00697406, version 1- 15 May 2012 same cross-modal paradigm and result from limitations in the same brain mechanisms.
