Fig 1. Comparisons of the changes in performances (pre-test minus post-test) between modes in each subtest of the Stroop/reverse-Stroop test.
Test 1 is reverse-Stroop neutral test, Test 2 is a reverse-Stroop incongruent test, Test 3 is a Stroop neutral test, and Test 4 is a Stroop incongruent test. Error bars represent standard error. The asterisk (*) indicates a significant difference identified by paired t tests (p = .008 adjusted by Bonferroni inequality).
