Verbal Reaction Times Experiment Essay -- Stroop 1935 experiment

This report aimed to replicate Stroops (1935) experiment. Using the repeated measures send off and a sample of 20 students, differences in verbal reaction multiplication on two tests were observed. The one-tailed hypothesis predicted that it would take longer to say haggle in the Cc, this is the conflicting condition where the colour of the vocalize differs from the colour that the word describes. It was found that, using the t-test for related data, this hypothesis could be accepted as the obtained value was much greater then the critical value. It can whence be concluded that visual interference does affect peoples verbal reactions. origin In 1935 John Ridley Stroop published his Ph.D. thesis entitled Studies of Interference in Serial Verbal Reactions - the findings of which became known as the Stroop event. Stroop mentioned many studies in his tap but the two that be most relevant for this report are Brown (1915) and Telford (1930), they co nducted very similar investigations into colour associations and colour recognition patterns respectively. This empyrean of research is known as controlled and automatic processing, it involves studies into how humans cope with divided up attention such as multi-tasking. This could be anything from the simple dishwashing and earreach to music simultaneously, to complex shadowing of continuous prose presented in one ear, whilst excessively typing up a separate prose presented to the other ear via headphones (Shaffer 1975). With their two-process theory, Shiffrin and Schneider (1977) arrive useful distinctions between controlled and automatic processing. They are as follows controlled processing... ...1930) Differences in responses to colours and their names. J. Genet. Psychol.
