Trial schematics for the two experimental conditions. Both conditions used typical visual search displays but interrupted the search process by presenting intermittent screens for unbiased pupil size measurement. Left: A trial in the visual search (memory) condition with the same search display presented during the entire trial; Right: A control task (no-memory) trial with a different search display after each intermittent screen
