Emotionally neutral task. As in the Baldwin, Whitford and Grisham (2016) study, we used colored shapes for the neutral (non-discarding) task. Participants were asked to choose blue shapes containing lighter colors (Go target) vs. darker colors (No Go distractor; see Figure 2). These shapes were matched in overall color composition and luminance to those in the discarding task. The trial structure was identical to the discarding task (see above) and participants were encouraged to respond as quickly and accurately as possible.
