ABSTRACT
This Psychology Internal Assessment will replicate J. Ridley Stroop’s (1935) Stroop Effect test. The aim of the experiment we will be doing was to investigate whether visual interference affects the cognitive processing speed (in seconds) in naming colored words. The research hypothesis states that the mean time to identify the

The Stroop Effect by J. Ridley Stroop will be replicated to investigate whether visual interference affects the cognitive processing speed in naming congruently and incongruently colored words. To further understand the results of the participant effects of the Stroop Test, this internal assessment will also look into Morton and Chambers’ (1973) Speed Processing Model, Shiffrin and Schneider’s Automaticity Model (1977), Cohen, Dunbar and McClelland’s Parallel Distributed Processing Model (1988).
In 1935, J. Ridley Stroop introduced a color naming experiment known as the “Stroop Effect”. The findings of his experiment showed that it was much faster and automatic for his participants to read a word compared to when they were instructed to name the color of the word. Stroop proposed that the participants of his study were much slower at naming the ink of the list of words, indicating that people automatically process the meaning of the word before perceiving color. This interferes with the ability to process color in the incongruent condition, and consequently delay the
