The Stroop Effect On The Brain

The Stroop effect is demonstrated by the reaction time to determine a color when the color is printed in a different color’s name. Participants respond slower or make more errors when the meaning of the word is incongruent with the color of the word. Despite knowing the meaning of the word, participants showed incapability of ignoring the stimulus attribute. This reflects a clear instance of semantic interference and an unfathomed failure of selective attention (Stroop, 1935).

The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In three experiments, participants had to name the color of one of two superimposed rectangles and to ignore words that appeared in the relevant object, in the irrelevant object, or in the background. The words were congruent,

Alansari and Baroun (2004) had participants state whether they were color blind, dyslexic, or if they had previously ever taken the Stroop test before, it was important that these interferences were factored out in order to obtain a conclusive observation in regards to all the participants involved in the experiment. MacLeod (1991) had suggested that those with disabilities tended to show high Stroop interference, also along with those with an attention deficit disorder since maintaining concentration throughout the experiment and test is an important factor in obtaining more accurate results without a significant outlier. Also different levels of interference where shown in children and adults, it was also observed that interference began at an early age, declined in the adult years since most have a peak of cognitive development and understanding in adult years, but once again increased interference around the age of 60 (MacLeod,

In the Stroop (1935) experiment he has proved that the effect is going to be one of the two slower or faster. In the non-conflict, some of the participants had to read two sets of words: set one with word written in their contradicting word so this has made it to be conflicting. Stroop (1935) came out to find that there are different association of words and the colors. Stroop (1935) wanted to see if they had any differences in the reaction time when the association was conducted. He noticed that the participants took longer read the conflicting word rather than the actual name word. The non-conflict was much easier and faster to do.

     I-Mac G3 computers and a program from Old Mississippi University were used to test the lateralized Stroop effect from http://psychexp.olemiss.edu. The name of the actual program was the Lateralized Stroop Experiment. The stimuli used by this program were colors that appeared laterally on a computer screen. Not only did the colors appear laterally but in differing hemispheres on the computer screen. The colors were in the form of written words. For example the word “red” was shown in green font. This was be an example of an incongruent stimulus because the written color word did not agree with the font color shown. An example of

At the point when the composed word is incongruent with the text style shading e.g. green written in cocoa, the time it takes to distinguish the shading is expanded in respect to a benchmark condition i.e. a string of rehashed letters, e.g. or a non-shading related word, e.g. stage. The contrast between the incongruent and gauge condition is known as Stroop impedance. Conversely, when the shading and word are consistent e.g. chestnut written in cocoa the time it takes to distinguish the shading is diminished in respect to the pattern condition; a distinction alluded to as Stroop assistance. Stroop impedance is putatively a result of reaction rivalry, and Stroop help an outcome of reaction meeting, different instruments creating Stroop impacts are thought to influence execution. At the end of the day the two measurements of the Stroop boost can give proof toward a reaction, bringing about contending or joining

The Stroop task helps us understand the process of our cognitive relation to attention. According to Zysset, Muller, Gabriele and Cramon, “The Stroop interference task requires a person to respond to a specific dimension of a stimulus while suppressing a competing stimulus dimension.” (Zysset et, al., 2001). In this case, The Stroop effect is performed with a challenging task and therefore an interference affects reaction time. Per say if an individual first is asked to read a color word such as YELLOW that appears in the font color red, and then asked to read the word and ignore the color font presented in, there is no level of difficulty associated with this task, as is with a black font color. However the

The psychological phenomenon called the Stroop effect was first popularized by John Ridley Stroop’s series of experiments (1935). Stroop investigated the conflicting stimuli of color identification and reading, and whether practice could diminish interference effects. His first experiment compared the speed at which it took participants to read 100 color-words printed in black ink with the same list of words printed in incongruent colors. Stroop found participants took an average 2.3 seconds longer to read black-printed words, which was, “…not reliable, which is in agreement with Peterson’s prediction made when the test was first proposed,” (p. 17). In his second experiment, Stroop compared the speed at which participants identified colored squares with the naming of ink color a color-word was printed

Overall, I think that the Stroop Effect is amazing. Not only does it befuddle our Inferior Temporal Cortex, in turn making us stop and think twice, but also increases our reaction times up to three-fourths larger than it should normally be! I also never knew that all three of the stimuli I am testing are located in the ame region of the brain. I hope that I can find a conclusion on my project’s overall driving question: Does changing the shape of incongruently colored words affect reaction

The “Stroop Test” or “Stroop Effect”, gets its unique name from Dr. John Ridley Stroop; in the 1930’s. The Stroop effect, charts a person’s reaction time to the task; these results will show the nature of the individual automatic processing versus their conscious visual control. The Stroop Effect involves positively identifying the color of the word listed instead of the word itself; as fast as possible. The test is based on two types of trails; congruent when words and colors match and incongruent when the words and colors do not match. The Stroop Test is a test that examines ones’ cognitive skills and level. According to Zaps, cognitive tests examine cognition, which is the mental activity that includes thinking and the understanding

The Stroop Effect is a demonstration of how the interference of conflicting information between the brain and the eyes can slow down the reaction time in some tasks. There are two parts to the experiment. A group of words is shown to the subject. The words are names of colors, but each word is written in a color different than the word. In the first test, people are timed to see how long it takes to say the color that is written. For example, if the word was “purple” then the test taker would say “purple”. Then, in the second test, people are timed to see how long it takes to say the color that is written when the word is printed in an ink color that is different from what is written. For example, if the word was “purple” and printed in red ink, then the person would say “red”. Many tests today are done very similarly, although the test that Stroop did was slightly different. ….

The study of interference in serial verbal reactions was coined by J.R Stroop and published as a journal of social psychology in 1935. The investigation focused on the interaction of stimuli and the effects on verbal reactions. The psychologists argued that interference of certain stimuli may affect the ease and convenience in performing verbal tasks. This simply means that interaction between certain counteracting stimuli may affect identification and interpretation of related and sequential verbal expected reactions. The most used concept in the experiment is the color stimuli. The authors exposed some students used as study subjects to certain color stimuli.it were evident that there were some difficulties in reading the colors, especially

We are replicating J.R. Stroop’s original experiment The Stroop Effect (Stroop, 1935). The aim of the study was to understand how automatic processing interferes with attempts to attend to sensory information. The independent variable of our experiment was the three conditions, the congruent words, the incongruent words, and the colored squares, and the dependent variable was the time that it took participants to state the ink color of the list of words in each condition. We used repeated measures for the experiment in order to avoid influence of extraneous variables. The participants were 16-17 years of age from Garland High School. The participants will be timed on how long it takes them to say the color of the squares and the color of the words. The research was conducted in the Math Studies class. The participants were aged 16-17 and were students at Garland High School. The results showed that participants took the most time with the incongruent words.

The goal of this rendition of John Stroop’s classic Stroop Effect experiment is to obtain and demonstrate the reaction time needed to mentally process the tasks given (colors and words) under the two different conditions (congruent and incongruent). A prediction of the result was made using the speed of processing theory, which implies that different tasks are processed cognitively at different rates, showing the difference in processing rates (times) for relevant and irrelevant information to the tasks. In our rendition, the classic experiment was slightly altered to include incongruent and congruent information, as well as the basic words and names tasks. Using the speed of processing theory we were able to make a hypothesis in

The aim of this experiment was to test cognitive interference. The Stroop Effect is the finding that naming words is easier than stating the color of the word. The Stroop Effect was first conducted in 1935 by John Ridley Stroop which was published in the “Studies of interference in serial verbal reactions”. This experiment was replicated by asking 40 participants to complete two different tasks. Task one involved reading words printed in different colors. The second task was to read the color of the printed word. Participants were timed while conducting task one and two. This experiment had a repeated measure and the participants included 20 girls and 20 boys. The independent variable was reading the test paper during both tasks. The dependent variable was the time it would take to complete task one and task two. Participants were asked to read the test paper as fast as they
