Test–retest reliability (temporal stability across sessions; Spearman–Brown-corrected correlation coefficients of Pearson’s r) and internal consistency (at each session; Cronbach’s α) of behavioral measures including all tasks, ignore/suppress, and suppress/remember comparisons, and separately for each task

aAll reliabilities were computed using the Spearman–Brown prophecy formula, rSB = k × r/(1 + (k – 1) × r), where r is the test–retest correlation and k the correction factor, which is 2 in all cases (i.e., same number of items in Sessions 1 and 2). Correlations between sessions (Pearson’s r) are reported in parentheses.
