This task is a nonverbal variant of the Digit Span task (Milner, 1971). The participant views a set of identical blocks that are spatially dispersed on the screen. The blocks are individually lit up in a random sequence. The participant is asked to tap each box in the reverse order of the sequence of lit boxes. This task is considered a task of spatial working memory as the sequence must be maintained and reversed in working memory in order to guide the subject’s response. Performance on this task is dependent on right prefrontal brain regions (Banich, 2004). The Corsi Block Tapping total correct score was used as the dependent variable in analyses.
