The Stroop Effect: Incongruent Color Words

The Stroop effect deals with the brain’s reaction when dealing with difficult or complex information. The brain’s competing functions are the cause of the delay or slow reaction time. Stroop relies on perception because of how the brain processes information from the environment by the senses. Due to the selective attention that occurs within people and the competing functions to process complex information, it usually takes a longer period of time for the participants to accurately identify between the two conditions of the color words. The replication of this experiment used Klopfer’s (1996) Stroop interference experiment based upon the color-word similarity.
Klopfer (1996) had two conditions that were presented to the participants, each with 40 words. The first condition had color words printed in the same color and the second had the color words were printed on in a different color. The aim of this experiment was to demonstrate an incongruent color-word creates a higher interference and errors than a regular color-word or neutral stimulus. Klopfer found that some color word representations yield more interference and some have more errors than others. The amount of errors found per color word in congruency in the Stroop effect showed within the normal yields of the original stimulus too.
Lovett (2005) performed an experiment to test double-response tasks by measuring firs the response to a word first, the test the differences related with the Stroop effect. The aim was to investigate if participants could exert enough control to perform the instructed task, even with the Stroop interference. There were four main tasks for the participants: color-only, word-only, standard Stroop, and double-response Stroop. These groups were organized into 48 random trials. The data used reaction times in milliseconds to see the effects of stroop. Reaction times were significantly higher in the stroop and double
