Stroop Effect
Results and discussion
INTRODUCTION
The Stroop effect is a classic cognitive psychology experiment discovered and first studied by J. Ridley Stroop in 1935.It originated from the theory of automatic processes. It is clear that some processing activities become automatic as a result of prolonged practice e.g. Typing, driving, etc. Automatic processes therefore are fast, require no attention and are unavoidable. Stroop believed that there was some evidence that word identification may be a form of an automatic process. In the experiment participants had to name the colours in which the words were printed as rapidly as possible. It was shown that naming speed was slowed when the words were conflicting colour names. The 'Stroop Effect' suggested that the word meanings were extracted when the participants were not attempting to process it. The original 'Stroop Effect' was illustrated using colour. The effect is demonstration of interference, in which the brain experiences slowed processing time because it is trying to sort through conflicting information. Interference was observed by Stroop that was the focus of his study. Various studies were also developed; one of them was on interference by Klein’s research in 1964 and Keele’s research in 1972.
INDIVIDUAL DATA
With reference to Table1: Colour alone naming times in seconds and interference increment times for colour-word units in the two conditions and Figure1: Comparison of the interference increment time in seconds in the two conditions. The colours alone time recorded for Participant 1 (Condition A) was 76 seconds and for scrambled colour word units was 88 seconds. Thus, the increment time was calculated as follows: for Condition A, interference Increment Time = Scrambled colour word units time minus Colours alone time, which was found as 12 seconds. Similarly, The colours alone time recorded for Participant 2 (Condition B) was 77 seconds and for incongruent colour word units was 149 seconds. Here the
