Abstract
This study develops a new computer-based Stroop/reverse-Stroop test and two experiments are conducted to examine the test's validity, its test-retest reliability and its practice/sequence effects. In Experiment 1, computer-based and paper-based tests were compared in terms of Stroop and reverse-Stroop interferences. The results indicated that, similar to the paper-based test, Stroop and reverse-Stroop interference can also be observed with the computer-based test. In Experiment 2, the computer-based test was administered three times with intervals, and the results indicated that the test-retest reliability is high and that although the practice effect was significant, no sequence effect was observed.
