Abstract The aim of this experiment was to investigate the efficiency of the Stroop Effect by making a partial replication on J.R. Stroop’s original experiment (Stroop, 1935).The independent variable of our experiment was the two conditions, the congruent and the incongruent conditions, where the list of words remained in black in the congruent whereas the list of words were printed in a variety of colours in the incongruent condition. The dependent variable was the time that it took participants to state the ink colour of the list of words in each condition. This experiment used “repeated measures” for the experiment in order to avoid influence of extraneous variables, and the 21 participants from an International School in Malaysia who were selected by convenience sampling, were presented with the …show more content…

According to Morton and Chambers’ (1973) assumption on speed of processing models, it is assumed that we are able to read words faster than naming colours. It appears that our mind chooses to receive specific presented stimulus before others. Due to this, when the word itself is a colour and the ink another colour it is harder to focus on only saying the colour of the ink, as the automatic process of reading takes over, and the two dimensions clash. However, this is not the case when the words are congruent. Thus, this assumption provides a strong possible explanation for the obtained
