The Stroop Effect

1494 Words 6 Pages
The Stroop effect is a demonstration of interference in the reaction time of a task. It is the finding that naming the color of the first set of words is easier and quicker than the second. When the name of a color (e.g., "blue", "green", or "red") is printed in a color not denoted by the name, (such as the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color. In his experiments, Stroop administered several variations of the same test for which three different kinds of stimuli were created. In the first one, names of colors appeared in black ink. In the second, names of colors appeared in a different ink than the …show more content…
For example, children, adults, teenagers, people with dyslexia, people with dementia, and people with different reading abilities each fall into a group of people with the same characteristics. People are put into these groups in order to compare the data and results gathered by the stroop test more accurately than comparing stroop test results from random groups of people. Research shows that reaction time to Stroop tasks decreases systematically from early childhood through early adulthood. These changes suggest that speed of processing increases with age and that cognitive control becomes increasingly efficient. Moreover, this research strongly suggests that changes in these processes with age are very closely associated with development in working memory and various aspects The Stroop effect is one of the most well-studied findings in experimental psychology(Stroop, 1935). This effect refers to the increase in response delay to name the color of ink in which a word is printed when that word is an incompatible color name relative to when it is an unrelated word or color patch. MacLeod (1991) wrote more than 700 articles that either directly examined the Stroop effect or used it as a tool to investigate other cognitive processes. The Stroop task has been especially useful as a tool to investigate stroop interference processes.

MacLeod, 1991). A major focus of the aging research has been on the amount of Stroop interference effects in younger and older adults. The typical findings are relative to baseline condition involving the naming of colors of simuli. Older adults tend to show a greater increase in reaction time and errors in naming of the print colors of incongruent color words than do younger adults (Cohen, Dustman, & Bradford, 1984). Although this data has sometimes been attributed to general slowing effects, others have complained that the larger Stroop effects in older adults than in younger adults support views that propose age deficits in particular cognitive processes(Verhaeghen & De Meersman,
