Experiment 1: Target-relevant WM load increased Stroop interference. (a) The meaning-comparison Stroop task display conditions used in experiments 1A and 1B. (b) Schematic trial of experiment 1A, which required maintenance of verbal information while performing the meaning-comparison Stroop task. (c) Mean RTs for each condition in experiment 1A. Stroop interference, indicated by the slope difference between incongruent and congruent trials, increased in the dual-task condition compared with the single-task condition. (d) Schematic trial of experiment 1B, which required maintenance of spatial information while performing the meaning-comparison Stroop task. (e) Mean RTs for each condition in experiment 1B. Stroop interference did not differ between single- and dual-task conditions.
