Abstract
The Corsi block-tapping task (CBTT) is a classic and well-established spatial working memory task in humans whichdemands internal computations (memorizing of Corsisequences, organizing and updating the memorandum,and recall processes) as well as (c)overt shifts of attentionto facilitate externalized rehearsal serving to maintain theCorsi sequences during the retention phase. To under-stand the relevance of (c)overt attention in CORSI tasks,28 participants had to solve different CBTT conditions(within-subject design), while eye position and pupil sizewere monitored. As CBTT, we introduced a novel anddigital version in which (a) the difficulty of the memoran-dum (sequence lengths reaching from 3 to 10) was con-trolled, (b) the execution of (c)overt attention during theretention phase was manipulated, and (c) (c)overt shifts ofattention were quantified. We present behavioral datashowing and characterizing for the first time the interindi-vidual variability but intraindividual stability as well as therange in deploying (c)overt attention strategies in CBTT.
