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).

An interesting challenge arises when a task such as color naming is identified as both controlled and automatic, by varying the other task involved. Color naming is identified as a controlled process when the other task is word reading, but as an automatic process when the other task is shape naming. Cohen, Dunbar and McClelland (1990) proposed an alternative explanation of the Stroop effect, which does not distinguish between automatic and controlled processing. Instead, they proposed that automaticity is a range, and that Stroop interference depends on the relative degree of learning the particular tasks, not on processing speed.

The Stroop effect was tested on four different tasks. Nineteen Queens College students were recruited by flyer, and each were assigned to a word reading task, color reading task, color inhibition task, and word inhibition task. They were timed using a stopwatch function on a cell phone, to name the color, or word to the quickest of their ability. In the order from longest reaction time to shortest: inhibition color naming task, color naming task, inhibition word reading, and word reading. This study shows that people can read words more quickly than they can name colors, and that inhibiting an automatic response to color/word tasks will take longer to do than tasks that do not involve inhibition.

The Stroop experiment by J. Ridley Stroop in 1935 was performed in order to analyze the reaction time of participant’s stimuli and desired results while also obtaining a collective result of color interference and word reading(Stroop, 1935; Lee & Chan, 2000). In the experiment three forms of the test were given, the first consisting of color patches, the second had the color words printed in black and the other was an incongruent test beaming the color did not match the color word

The aim of this experiment is to study autonomic processes by replicating the previously carried out Stroop effect by using numbers. A number of 180 random participants aged in between 18-89 were recruited to participate in this experiment. Participants were presented with a stroop experiment task sheet which consists of three parts which was the control, congruent and incongruent conditions. Time was taken and recorded for each participant to say out the number of stars in the control condition and to say out the number of numbers in the congruent and incongruent conditions. Based on the results, participants took a considerably longer time to say the number of number in the incongruent condition than in the congruent condition.

The Stroop test consisted two major posters of word lists: Incongruent list and Neutral list. Each poster included 20 words in 2 columns of 10 words each. All letters were stenciled, capitalized and 1 ¾ inches high. Both incongruent and neutral words were listed on the 56 x 71 cm posters Stopwatch with 0.01-second accuracy was used to time to measure how long participants took to read both incongruent and neutral word lists, which is a dependent variable for this experiment.

The experiment is a demonstration of reaction time of a task . The Stroop experiment employs two basic processes of cognition; attention (“the concentration of mental effort on sensory or mental events”) and automaticity (“a cognitive process that does not require conscious thought as a result of existing cognitive structures

Controlled Vs Automatic processes: A modified version of a Stroop experiment using colour-associated and colour neutral words.

In the control group, Stroop (1935) printed all of the words in black. In both conditions, Stroop (1935) printed the words twice in each row and twice in each column. Stroop (1935) did not print the colors in the corresponding color of ink and also did not repeat words in a row or column. For his first experiment, Stroop (1935) used 70 college student volunteers. Half of the students (half of each sex) completed the control, then the experimental sheet, then experimental sheet again, and then the control (Stroop, 1935).

The results of the information processing lab support the text in a number of ways. As the number of choices increased, the total response time also increased, verifying Hick’s Law. This then indicates that as the trials became more complex, information processing time was influenced. However, the subjects were able to bypass the complexity of the task when they were able to preview the color or

In the Stroop task, participants are asked to name the colour of the ink that a colour word is written in, while ignoring the written the word (Goldfarb et al., 2011; Raz et al., 2006). The task is comprised of congruent words, where the ink colour and the written word match and incongruent words, where the ink colour and the written word do not match. The Stroop task has illustrated that participants respond slower and less accurately when the word is incongruent compared to when it is congruent (Goldfarb et al., 2011; Raz et al., 2006). The difference in the accuracy and speed of responses between the congruent and incongruent words is called the Stroop Effect (Goldfarb et al., 2011; Raz et al., 2006). Research has suggested that this occurs

We often tend to live our everyday lives without paying much attention to the factors that contribute to our every movement and function. Have you ever wondered what triggers your brain to complete simple tasks, such as reading road signs, or knowing how to follow a guided set of instructions? John Ridley Stroop became specifically interested in the part of the brain that measures selective attention [1]. Oftentimes, in order to maintain balance, the brain will carry out the action that is most common and easy and will stop the action that will take more work and effort. The process explained in the previous sentence is known as inhibition, and it regularly occurs in our minds [2]. Stroop gave participants a list of colors, such as green,

The stroop effect is a strange phenomenon when your right and left side of your brain have a conflict about what the word says and what color the word is. I am going to make a project to examine everyone’s attempt and graph it. I am going to see if the difficulty is harder or easier compared to the age and gender of the challengers.

The participants were also told to draw a line in an ascending pattern (from 1 to A; A to 2; 2 to B and so on)” and join all numbers and letters together. However, low scores in both parts of the TMT tests indicate an improved performance (Hayes et al., 2011). Another six studies test performed during the study was Stroop Color and Word test. The test score was based on observing the participants performance. The participants were asked to call out the color letters printed in black ink in 45 seconds. They mentioned color of letter Xs. Moreover, colored words test was also given where participants were to call out the color written in contrasting color ink (example the word ‘red’ printed in blue ink), and were asked to mention the ink color that the

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.
