The Stroop effect is a classic psychology experiment that demonstrates the interference of automatic and controlled processing in the brain. It was first conducted in 1935 by psychologist John Ridley Stroop, and has since been used in countless studies to explore various aspects of cognitive psychology.

In the Stroop experiment, participants are presented with a list of words that are written in different colors. The task for the participants is to name the color of the ink that the words are written in, rather than reading the words themselves. For example, if the word "red" is written in blue ink, the participant should say "blue," rather than "red."

The Stroop effect is observed when it takes longer for participants to name the color of the ink when the word itself is a color name that is different from the ink color. For example, if the word "red" is written in blue ink, it takes longer for participants to say "blue" than if the word "green" was written in blue ink. This is because the brain has to suppress the automatic tendency to read the word and instead focus on the ink color, which takes longer.

There are several variations of the Stroop experiment, including using different types of stimuli (e.g., numbers, shapes) and manipulating the size, font, and arrangement of the stimuli. These variations allow researchers to investigate how different factors influence the Stroop effect and how it relates to other cognitive processes.

Overall, the Stroop effect is an important finding in the field of cognitive psychology that highlights the complexity of the brain's processing of information. It has been used to study a wide range of topics, including attention, perception, and decision-making, and has contributed to our understanding of how the brain works.

Experiments are conducted in a variety of areas chosen to give students an appreciation of the range of current psychological research. The communication with participants was provided in an appropriate and correct manner to minimize any misunderstandings. Furthermore, when examining the single data point that this assignment required, the hypothesis was also supported because the RT increased and the accuracy reduced. If the participant does not respond within the designated time or makes a mistake, a short sound is played, and the next card appears on the screen. In light of the previous analysis, a different scoring method for all three tests is recommended that fills the two main requirements.

How the Stroop Effect Works

stroop effect experiment report

It was shown that naming speed was slowed when the words were conflicting colour names. The Stroop effect occurs at multiple points along a cascade of control: Evidence from cognitive neuroscience approaches. Participants were presented with a stroop experiment task sheet which consists of three parts which was the control, congruent and incongruent conditions. If this study was to be conducted again the following changes should be made. It is therefore obvious that two-processes are operating simultaneously and when they are triggered at same time towards the same goal they interfere. The informed consent is signed to retrieve the agreement for processing the information collected during the experiment. The versatility of the Stroop task paradigm lends itself to be useful in a wide variety of fields within psychology.

Introduction The Stroop test investigated the reaction times in milliseconds to colour congruent and colour incongruent words with the aim of gaining knowledge about the mechanisms of selective attention, including its capacity and processing speed. The result shows that the reaction time is indeed affected by the degree of rotation; therefore, it demonstrates the hypothesis that people can mentally rotate images. Studies of interference in serial verbal reactions. However, the sample was dominantly female which may have had an influence on the overall results. The test was run on iMac IOS desktop computers.

. Therefore, the materials used for the procedure include a computer and software that presents the experiment. All the participants were male. The program contains three types of cards representing each of the three task conditions. In such a manner, they attempted to measure more complex issues related to interference.

Overall, the results retrieved during the experiment on the Stroop effect are consistent with those demonstrating the average summarized data collected from 1476 participants. The primary purpose of this study was to determine whether the Stroop phenomenon is equally strong in both brain hemispheres. The third set of cards is used to test a facilitating condition and presents the cards with words, meanings, and the ink color of which are consistent. This made it hard for the participants to concentrate. Finally, further research on the topic of study should be mentioned and a review on the methodology of the experiments should be testified. Design: The design of the study was repeated measures since each participant took part in both the colour congruent and the colour incongruent condition.

Neuropsychology, 15 4 , 462—471. The interference occurs when we try to use System 2 to override System 1, thus producing that delay in reaction time. The current study measures response times based on four different exercises involving the reading of numbers and row length. Again, a separate response sheet was used to track the progress and identify errors that occurred. Each trial was presented as either congruent e. Much investigation has been made to expand the clinical, theoretical, and scientific implications of the issue.

Studies of interference in serial verbal reactions. In regard to the Stroop task, slowing to a response conflict was identified to be due to failure of selective attention or lack in cognitive efficacy. There are some methodology problems in this experiment design. First, the paper focused on the research plan involving such aspects as hypotheses and methods where the latter specifies the design, procedure, materials, and other relevant components of the experiment. Stroop, the first person to publish its significance in English in 1935 Stroop, 1935. Half a century of research on the Stroop effect: An integrative review. As seen in the experiment, the confusion led to either prolonged answers or many errors if they answered it too quickly.

However, as the experiment commenced and inhibition of an interference was required, some difficulty became apparent. Figure 1: Bar graph with error bars showing the distribution of scores. Response and encoding factors in ignoring irrelevant information. Precisely speaking, a great emphasis is placed on the degree of automation of such processes as a reading of words when a person does not delve into the meaning while reading them.

. In order for people to figure out what action needs to be performed regarding an object or event, information has to be gathered on the object that is to be reacted against. Participants were provided with a paper consisting of different colours in basic text format. Hence why it is guaranteed that incompatible words will cause interferences when attempting to name their printed colours. PLoS One, 8 10 , 1-8. The scores of a single participant were compared to the mean score of a sample as it was required to do so for an undergraduate assignment.

According to Flaudias and Llorca 2014 , the basis of this effect is the difference between theoretical and practical logic of visual perception. The difference between number and group of digits created a conflict within the brain that needed more time to process. Such behaviour indicates a chance of failure to maintain consistency of the experiment, even if the participants properly completed the task. To predict the outcome of the hypotheses, inferential statistics were used to make inferences based on the relations found in the sample. 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. In this condition, the participants were told to respond faster if the response time was slower than supposed to be and were also informed whether the key pressed for each coloured word was accurate or not. Firstly, following the original methodology both accuracy and speed must be tested but independently of each other through a computer-generated process.
