The Stroop effect is a phenomenon that occurs when an individual has difficulty naming the color of a word if the word itself spells out a different color. This interference occurs because the brain processes the meaning of the word faster than it processes the color of the word, resulting in a delay in response time.
The Stroop effect was first described by John Ridley Stroop in 1935, in a paper titled "Studies of Interference in Serial Verbal Reactions." In this paper, Stroop presented the results of a series of experiments in which he asked subjects to name the colors of a series of words that were either congruent (e.g., the word "red" printed in red ink) or incongruent (e.g., the word "red" printed in green ink). He found that subjects took longer to name the colors of the incongruent words and made more errors than when the words and colors were congruent.
Since its discovery, the Stroop effect has been the subject of numerous studies and has been used to understand various aspects of cognition and attention. For example, the Stroop effect has been used to study the effects of aging on cognitive function, the role of executive function in cognitive control, and the neural basis of attention.
One important use of the Stroop task is as a measure of executive function, which is a set of cognitive processes that allow individuals to control their thoughts and actions. Executive function is important for tasks such as planning, problem-solving, and impulse control. The Stroop task is often used to measure executive function because it requires individuals to inhibit their automatic response (naming the word) and instead name the color of the ink. This ability to inhibit automatic responses is thought to be mediated by the prefrontal cortex, a brain region involved in executive function.
In addition to its use in studying cognitive function, the Stroop effect has also been applied in clinical settings. For example, the Stroop task has been used to assess brain damage in individuals with traumatic brain injury or stroke. It has also been used to evaluate the effectiveness of treatments for conditions such as ADHD and addiction.
Overall, the Stroop effect is a fascinating and well-studied phenomenon that has shed light on a wide range of topics in psychology and neuroscience. It continues to be an important tool for understanding cognitive function and has practical applications in clinical settings.

For each of the 96 trials, participants were presented with a word and prompted to clicked appropriate colour button to identify the colour the word was printed in, as rapidly as possible. Using this information, means and standard deviations were calculated for the reaction times in each condition of the experiment. The study introduces the overview of the research conducted on the topic within a century of scientific work in the field of psychology. The experiment helped us examine the horse race model, which consist of the phenomenon on interference and automaticity. Other experiments have slightly modified the original Stroop test paradigm to provide additional findings. Since the experiment will involve three different conditions, including neutral, consistent, and inconsistent, the response time will be different for each of them due to the level of interference between stimuli. Discussion The results of the current study support the hypothesis.
The study aimed to conduct the Stroop test to determine whether there is a difference in the reaction time for congruent, non-congruent, and neutral images. The Stroop test can also be expanded and applied to measure the processing speed, capacity and skills, and processing abilities of different individuals. The speed of processing is a theory that observes that the processing of written words is usually faster than that of colors. Half a century of research on the Stroop effect: An integrative review. We can tell our brain to do lots of things — store memories, sleep, think, etc. The hypothesis was tested by asking participants to recall the color of the text in the control condition while being timed; this was repeated in the experimental condition. The study also revealed that the specific color-identification task could interfere with the working memory.
How is reaction time which is how fast you can do something related to the Stroop Effect? The independent variable was the condition of the stimuli with 3 levels low, medium and high interference conditions. Proceedings of the National Academy of Sciences USA. Expand It is found that visual noise interfered more with concrete versus abstract word processing, but only when the task required visual information to be accessed, suggesting that basic visual processes can be causally involved in language comprehension, but that their recruitment is not automatic and rather depends on the type of information that is required in a given task situation. However, the overall findings prove the validity of the Stroop effect and might be used for further research in cognitive psychology. The Stroop effect contributes to the studying of individual differences in cognition, mental conditions, the flexibility of attention, and other psychological particularities. Upon the completion of the experiment, the results table is displayed that demonstrates the data retrieved during the procedure. The delay in reaction time reveals that it is much harder to name the color of a word when the word itself spells another color the incongruent stimuli than it is to name the color of the word when the word itself spells that same color the congruent stimuli.
Participants received instructions orally and were asked if they had any questions before we continued with the experiment. Overall, the Stroop effect is a very complex theory that is still being studied today and is very important to understand as it relates to the functions of the brain and eyes and is used as an important measurement or when testing for 5 Major Eye Movements 781 Words 4 Pages Sight is one of the special senses and it is accomplished with an organ called the eye. The experiment measured whether visual attention shifting led to a difference in automatic and non-automatic responses. Along with our second hypothesis stating that there is greater interference Stroop effect when color words are incongruent with their presentation color. The results would have a significant impact on psychology as they would show the approach to processing information. The incongruent mean reaction time was higher than that of congruent and neutral times. .
Introduction to Stroop Effect Research Paper Essay Example
The Stroop effect was first published back in 1935 by American psychologist John Ridley Stroop, although discoveries of this phenomenon date back to the nineteenth century Stroop, 1935. The amygdala job is to determine if incoming information is necessary for survival. Lewis 2 Abstract The Stroop Effect is a delay in reaction time between congruent and incongruent stimuli. The results were supported using an ANOVA with repeated measures. I have always read quickly, but I have also always had to reread for comprension because of reading too quickly.
Also, there was no significant difference between the low and medium interference levels. Some people have the ability to practice reading at a very young age. Today, the Stroop task is very well-known and is applied in both clinical settings and for educational or training purposes. The findings of The Stroop Effect demonstrate how difficult it can be to only concentrate at one thing. The DLPFC assists with memory and executive functioning, and its role during the task is to activate color perception and inhibit word encoding.
According to this theory, reading is an automatic process which we are incapable of turning off, similar to our automatic body functions such as the beating of our heart. In the 1930s, described by psychologist John Ridley Stroop, the Stroop effect is our tendency to have trouble naming a physical color when used to spell the name of a different color. One of the major limitations of the study was the limited sample size of 11 participants. The selective attention theory observes that information that requires selective attention will undertake further awareness and processing that will be ignored. In accordance with the claims made by Megherbi et al.
Additional Research Additional Research John Ridley Stroop helped lay the groundwork for an abundance of future research in this field. The ACC is responsible for selecting the appropriate response and to properly allocate attentional resources Banich et al. The four colors used either as the ink color or as the words naming the colors are red, green, blue, and yellow. Once all the conditions are done, the experimenter and participant swap roles. Selective attention theory: Selective attention theory : The theory of Because of this, the brain needs to use more attention when attempting to name a color, making this process take slightly longer McMahon, 2013. However, the neutral and incongruent words are non-habitual actions that can be developed through repetitive actions.
