Schematic of a Directed-Attention Task and a Working-Memory Task. NOTE: (a) Schematic of a directed-attention task with central, symbolic arrow cues indicating the possible future location of a target letter. A speeded decision is required, indicating whether the target is consonant or vowel. (b) Schematic of a working-memory task in which the location of 1, 2, or 3 dots had to be remembered over a 3 sec delay. A decision is required about whether the test dot (shaded dot) appeared in the same location as one of the target dots (black dots).
