Exploring the Stroop Effect by using numbers
Abstract
The purpose of this experiment is to study automatic processes by replicating the previously carried out Stroop effect by using numbers. This experiment was conducted by recruiting 8 participants (4 males and 4 females), who are working in a head-office of Save the Children Organization in Yangon, selected by an opportunistic sample. Participants were presented with a Stroop-experiment-task sheet which consists of two parts which was the congruent and incongruent conditions. Time was taken and recorded for each participant to count the number of digits in the congruent and incongruent conditions. The results found that the participants took a significantly longer time to count the

The null hypothesis is that there will be no difference in the length of time taken for participants to count the number of digits on incongruent list and the length of time taken to count the number of digits on congruent list. (Word count= 534)
Method
(a) Research design: The repeated-measures design was used for this experiment, so all subjects experienced each of the experimental conditions. In other words, the experiment was a within-subject design. The independent variable was the incongruent and congruent stimuli and the dependent variable was the time taken to count the number of the digits. The incongruent condition was the "Stroop" condition, and the congruent condition was controlled condition. No change was made to the independent variable, meaning the design is parallel between the values of the dependent variables attained from incongruent and congruent conditions for each participant. Confidentiality of participants had to be ensured, by anonymity. (b) Subjects: The subjects were 4 males and 4 females between the ages of 30 and 36. All participants were staffs who are working in a head-office of Save the Children organization in Yangon, and they all are graduated. They are selected by using the convenience sampling method. (c) Materials: Two lists of numbers were used as stimulus materials. In List 1, there were 32 congruent stimuli – the number name and the number of
