本实验采用混合2×2因子设计，实验有两个变量:一个重复测量变量和一个独立测量变量。在重复测量变量中，参与者暴露在这个变量的两种条件下(一致和不一致)。为了减少练习效果，平衡练习顺序，有一半的人先做一致条件，然后做不一致条件，另一半人先做不一致条件，然后做一致条件。然而，“标准”组的参与者和“改良”组的参与者是不同的，这些都是独立的测量方法。所有的参与者被随机分配到每个条件中。有两个自变量:油墨颜色和文字是否一致(相同)或不一致(不同)，以及文字是否易于阅读或包装。因变量是参与者正确说出颜色单词列表中墨水颜色所花费的时间。参与者在一个没有干扰的安静房间里接受测试，他们被要求阅读并签署信息表和同意书(见附录)。有两组:完成正常Stroop任务的“标准”组和完成相同任务的“修改”组，但在一致和不一致的条件下(缠绕Strop任务)，单词被缠绕。在“标准”组中，所有的参与者坐在一张桌子旁，给他们一张纸，纸上有一份颜色单词表，要求他们大声说出单词的墨水颜色，而忽略单词本身。参与者必须正确地识别出单词的墨水颜色，才能继续下一个单词并完成列表。在参与者开始之前，他们被告知他们应该尽可能快和准确地识别单词的墨水颜色。完成第一个清单后，参与者有一分钟的休息时间，然后进入第二个条件，同样的程序进行。在“修改”组中，指令与“标准”组相同。实验人员会记录下参与者正确说出所有单词的墨水颜色所花费的时间(以秒为单位)，并进行分析。

 The design used for this experiment was a mixed 2×2 factorial design, the experiment have had two variables: one repeated-measures and one independent-measures.  In repeated-measures variable, participants were exposed to both conditions of this variable (congruent and incongruent).  To reduce the practice effects and counterbalance the order, half of the participants made the congruent then the incongruent condition and the other half of the participants made incongruent then the congruent condition.  However, participants in the ‘standard’ group, were different to participants in the ‘modified’ group, these were independent measures.  All participants were randomly allocated to each condition. There were two independent variables: whether the ink colour  and the word are congruent (the same) or incongruent (different) and whether the words are easily readable or wraped. The dependent variable was the time taken for participants to correctly name the ink colours of a colour word lists. Participants were tested in a quiet room away from any distractions, they were asked to read and sign the information sheet and consent form (see the Appendix).  There were two groups: a ‘standard’ group who completed the normal Stroop task and a ‘modified’ group who completed the same task but in the congruent and incongruent condition (wraped Strop task), the words were wraped.  In the ‘standard’ group all participants seated at a table and were presented a piece of paper including a colour word list, they were asked to identify the ink colour of the word by saying it loud, ignoring the word itself.  Participants had had correctly identify the ink colour of the word to be able to move onto the next word and finish the list.  Before the participants started, they were told that they should try and identify the ink colour of the word as quickly and as accurately is possible.  Participants after finished first list had one minute break before participating in the second condition, in which the same procedure was carried out. In the ‘modified’ group the instructions were the same like on ‘standard’ group.  The amount of time was taken (in seconds) for the participants to correctly name the ink colour of the whole list of words, was recorded by the experimenter and analyzed.
