基于电脑的新Stroop/逆Stroop测验——测验的信效度、练习及顺序效果

A new computer-based Stroop/reverse-Stroop test:The validity,reliability,effects of practice and order of the tasks

本研究设计了新Stroop/逆Stroop电脑测验,并采用两个实验分别探讨了该测验的信效度、练习及顺序效果。实验1采用新Stroop/逆Stroop电脑、纸笔测验分别对被试进行了测试,结果表明两测验成绩相关显著,两测验均能成功地测试到Stroop/逆Stroop效应,这也表明新Stroop/逆Stroop电脑测验的效标效度是比较高的;实验2采用不同的测试顺序对同一批被试反复进行了三次电脑测试,结果表明:在每个分测验中3次测试的成绩均存在相关显著,这说明新Stroop/逆Stroop的电脑测验的重测信度较高。研究同时发现,测验的练习效果不显著,但测验的实施顺序对测试的结果有显著影响。研究建议,在对该电脑测验进行施测时应固定测试顺序,以提高结果的稳定性。

In this paper,two experiments examined whether the Stroop/reverse-Stroop interference can be observed by the newly designed Chinese version of the computer-based Stroop/reverse-Stroop test,the test validity,the test-retest reliability and the sequence effect of computer-based test as well. In Experiment 1,Stroop/reverse-Stroop interferences were compared between the computer-based and paper-based tests. The results showed that both Stroop/reverse-Stroop interferences occurred in the computer-based test,and a high correlation was identified between the two version tests. In Experiment 2,the test-retest reliability and test sequence effect were only examined in the computer-based test conducted for three times with intervals. The results showed that the test-retest reliability was high,while different test sequences affected the test score. This suggested that the new-ly designed computer-based Stroop/reverse-Stroop test was a valid and reliable tool for evaluating Stroop/reverse-Stroop interference,while the test sequence should be fixed.
