Abstract
The aim of this experiment was to establish the cognitive interference on attention that’s caused by conflicting stimuli, this is measured by the difference in reaction time in participants who are asked to name the color of words with conflicting meanings when compared to participants that are given a list of words with non-conflicting meanings. The experiment was a partial replication of J. Ridley Stroop’s experiment done in 1935. This experiment utilizes convenience sampling to gather grade 12 students aging from 16 to 18, 24 participants were gathered with 12

This results could be explained as the experimental group had the interference. There is also an increase in standard deviation for the experimental group when compared to controlled group. The standard deviation shows the spread of data of the experiment, this increase in spread for the experimental group could be due to some participants having done this experiment before, since the stroop experiment is fairly well-known and could be on social platforms like Facebook and YouTube, some participants could have done this experiment on these platforms, this will allow them to have increased speed when compared to participants that have never done the experiment before. Having done
In the original study done by Stroop, there’s on average an increase in time of 2.3 seconds to read 100 colors names printed in colors different from that named by the word than to read the same names printed in black (Stroop, 2016). This result is largely in line with the results extracted from this
