In a research using the Stroop task to demonstrate Stroop interference, the present study analyzed the response time in different conditions and compared the incongruent condition to the facilitated condition. The purpose of the Stroop effect experiment is to ascertain our attentional capabilities in terms of variability and flexibility. Therefore, if various words were displayed in different color ink with the color on the words different, we definably will have difficult time telling the words apart from the color. There were 150 participants involved in this experiment. The participant was required to look at the colored words and the color on the ink while ignoring actual words. The results were that the reaction time was high and few errors were made in that congruent condition. At the end of the study, it is conclusive that when the process of reading is a simple automatic process, simple tasks like color identification becomes difficult for a person


Stroop effect is one of the phenomena in cognitive science and psychology. Introduced in 1935, Stroop effect originated from theory of the automatic process. We are used to some of the processing activities until we have gotten used to them and have become automatic. for instance, driving a car, typing. These processes have formed part of our automatic response unit, where they are unavoidable, fast and does not require ant attention. Stroop had a belief that identification may be part of automatic process. He argues his belief by conducting an experiment where participants had to read sequence of words printed rapidly. It was noted that naming slowed down when colors and names conflicted. The Stroop effect suggests that extraction of words meanings happened as participants were not attempting to process it.332hbs the prefinal scoop effect was found.

Effects of the Stoop Effect on Response Time

The Stroop effect has been and still is one important topic in experimental Psychology. The Stoop task is still used today to study several other topics and to investigate the effects of many different things on the human and animal mind. The Stroop Effect is a test used to demonstrate the reaction time of a task. Because of its versatile nature, it can be used to determine the effect of various variables on response time”and therefore the processing time”, illustrating differences between automatic processing versus conscious visual control.

In this paper, I aim to analyze the findings of our own Stroop task performed in our Research Methods in Psychology class at Florida Atlantic University, and tie that to previous experiments done in the past. I aim to explore similarities and differences between our experiment and theirs and to examine the variables involved in our experiment and what they mean to the overall results of the Stroop Effect.

The Stroop effect is tested using two or more groups of words that match the other groups in frequency (Thorndike and Lorge 1944), number of letters, and number of syllables.
