104 Distance Education University students took part in this study, as part of an assignment to analyse the effect of Interference when completing the Stroop task. Participants were given a series of stimulus to set up the experiment. Each person had a turn of being both the participant and the experimenter. A series of four timed tests were given to individuals who required them to read out aloud the colours that were written on the page. The hypotheses being tested were; interference would be seen when trying to read word colours when they were written in another colour; pronounceability of words has an impact on interference and slowing down the word recognition response would reduce the amount of interference. Support for all the hypotheses was found through a paired sample T test.
Knowing how the brain functions and the effect this has on different situations is a key factor in Psychologists treating patients (Cohen, McCelland & Dunbar, 1990). In 1955 Psychologist John Ridley Stroop undertook an experiment to explain ‘interference’ and the effect this has on different situations. The Stroop task, and its many variations, is a commonly used tool in cognitive psychology to explore how different types of behaviours interact and the nature of attention and automaticity (Besner, Stolz & Boutlier, 1997).
Cohen et.al. (1990) states, attention focuses on two types of cognitive processes, controlled and automatic. Controlled processes require attention, and are relatively slow, whereas automatic processes are fast and do not require attention for their execution. Besner et.al. (1997), believed reading to be an automatic process as readers cannot refrain from...
