Reaction_Time

Reaction Time Racial Differences in Reaction Times It has often been argued that the racial differences in intelligence test performance may be due to the test being biased or to a variety of environmental factors such as differences in education, experience of dealing with visual representations, motivation, attitudes towards test taking and nutrition. The alternative theory is that these differences have a genetic basis. In order to test for which of these different explanations is correct, a study has been carried out to determine whether the racial differences in intelligence are also present in reaction times. The rationale of the study is that reaction times provide a measure of the brain’s neurological efficiency in dealing with very simple tasks and are unaffected by education, motivation and other environmental factors with the possible exception of extreme malnutrition. It has been shown in a number of studies that reaction times are positively associated with intelligence, and the explanation widely accepted for this association is that reaction times provide a measure of the neurological efficiency of the brain in analysis and decision-making.
