The Stroop Effect

Superior Essays
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,

    There are two main theories of processing perception, top-down processing and bottom-up processing. Bottom-up processing states that the environment gives all of the cues needed to guide the perception of the world around you. Top-down processing implies that your mind’s expectations for what you are about to see guide your expectations and your mind uses these expectations to adapt to reality (Psych 240 lecture, 09/21/16). The study reinforces the idea of top-down processing in showing that the reaction times are slower and there are more errors when the flanking characters are ambiguous as well. This result of Experiment One shows that an unclear context can truly make a difference in how we perceive things.…

    The second Stroop trial was harder because I was focusing more on the word instead of focusing on the color of the word which made it more difficult to process. I followed the expected pattern and on the second phase and it was a little easier because I expected the words and colors to be different. Briefly (2-3 sentences) define, in your own words, the Stroop Effect: The Stroop effect shows how individuals process information differently when we try to associate it with words…

    They modified it so they could manipulate the categories of distractors while still controlling bottom-up factors (Avital-Cohen & Tsal, 2016). The independent variable in their experiment is the type of distractors, meaning whether they are incongruent or congruent. Another independent variable is the letter or word condition. The dependent variable is the reaction time. They chose S or O for target letters and set two conditions.…

    In Alan Baddeley’s article, “Is Working Memory Still Working?” he broke down the components of working memory in an attempt to discover if it still works efficiently. After analyzing multiple studies, the conclusion that working memory has always worked, and still works, was developed. While Baddeley gave a systematic and detailed analysis of applicable research, there are several issues with this article. Throughout the article his tone lacked confidence, tenses switched frequently, figures were not provided correctly, colloquialisms were used, the grammar was inconsistent and contained errors, and data was not provided, despite numerous references.…

    The paper evaluates research article that discusses current research of how bilingual advantages in executive function depend on characteristics of the participants and features of the tasks. Compared with monolinguals, bilinguals show superior performance in versions of such tasks as the Simon task, Stroop task, and flanker task. All these tasks require resolving conflict from distracting cues, switching efficiently between types of trials, and maintaining rules in working memory, all components of executive functioning system. Three main questions considered in the research.…

    Studies done by Stroop (1992) and Windes (1968) suggest that the Stroop effect occurs when performing a naming task which impacts reaction times. In the Stroop (1992) study found that color naming had a slower reaction time when the color words were printed in a different color, but even slower reaction time occurred when the color and word were completely separate from one another. The current experiment used Stroop task to determine the impacts of reaction times to test the hypothesis to see if there is a significant difference between the reaction times amongst the four levels of the Stroop task. Specifically seeing if the naming of color words printed in the same color had faster reaction times than naming the color of word printed in different…

    In the test, subjects are shown the names of colors in colored letters. The color of the letters does not match the name of the color given. It takes mental effort and concentration to see past the word and just identify the color of the word. The authors used this test to identify how racist decisions affected the results of the test. Thus, the dependent variable was cognitive ability and it was measured by the Stroop test.…

    I found this topic interesting because teachers are usually against chewing gum in the classroom and saying that it is distracting. My goal for this experiment is to prove that chewing gum helps with concentration and to get teachers to allow kids to chew gum during tests and quizzes. All of the research I was able to obtain completely supports my hypothesis. Each of my sources suggest that chewing gum makes a difference. Chewing gum is good for the brain and can boost alertness by 10%.…

    Ryan’s cognitive abilities were assessed through the use of the Wechsler Intelligence Scale for Children (WISC-V). The areas of cognitive processing ability measured include crystallized intelligence, short-term memory, visual-spatial processing, reasoning ability, and processing speed. The subtests measure different cognitive processing abilities, combining to form five index scores: Verbal Comprehension, Visual-Spatial, Fluid Reasoning, Working Memory and Processing Speed which all together make up the Full-Scale IQ score. Ryan obtained a score of 118 (88th percentile), which falls within the Above Average Range. Ryan’s indexes ranged from a composite score of 123 on the Fluid Reasoning Index (94th percentile) to a composite score of 98…

    The results offered evidence that the participants were inclined to the grouping, sorting and pattern activities (Tasks 2, 3, 4, 5, 6 and 7); they exhibited a good-excellent performance with minimal support from their tutor. In terms of their response time, Neil, Eric, Tom and James were able to effectively complete the tasks within a mean response time per object lower than 3 sec. However, they generally needed more time to respond to the sorting, memorizing and assembling tasks (Task 1, Task 5 and Task 8), thus confirming existing research findings about the difficulties associated with poor spatial working memory when persons with ASD use complex visual information (Blair et al., 2002; Schuh & Eigsti, 2012; Williams, Goldstein & Minshew, 2006). Nevertheless, they were generally able to reproduce spatial patterns if previously they…

    Introduction Sleep is an important component for maintaining, sustaining, and optimizing academic performance. Different lifestyle needs fluctuate the amount of sleep between individuals and often led them to attain inadequate sleep. Sufficient sleep has been linked to the enhancement of emotional and social function, whereas insufficient sleep reduces cognitive function and negatively affects academic readiness (Deuster & Yarnell, 2016). Researchers at the University of California, Los Angeles have collected data on performances based on sleep patterns on participants through a series of tests known as the Computer Memory Interference Test (CMIT).…
