The Stroop experiment can be traced back as far as the nineteen century around the time of some particular works of Cattell and Wundt. The experiment was first written about in 1929 in German. The experiment was name after John Ridley Stroop after he had written the article “Studies of interference in serial verbal reactions,” which was published in 1935.there have been over 700 replications of 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 or highly practiced tasks.”). The Stroop Effect is all about being able to say the colour of the word and not the colour the word are saying. For example, the word “red” is portraying the colour green so instead of saying the colour is red you say green. It said that it is easier to make out the colour when it is the same as the word “red” (congruent) than saying the colour of the word when the word has a different color than it is portraying “blue” (incongruent). In this case it is that inference is taking place.
Upon choosing an experiment to do, one stumbled upon of the experiment of the Stroop Effect under the categories of attention and automaticity. It created an intrigue in one, which caused one to choose it as his or her experiment. Firstly, after clicking on the experiment, one had to choose the setting that best suited him or her. One chose to do two trials of the experiment. The first trial one chose to have the condition to be congruent words, the colour of the words to be red,...

...colours are read at a slower rate when they do not match with words with a different colour. Also, they stated what causes the actual interference is when two responses are competing for responses that should be produced. All in all, this can affect the reading reaction time. In some cases the reaction time can be as perfect. That is when it only has congruent word, and sometimes it may not be so perfect because of interference. This can be caused by incongruent words.

Essay about Describe Stroop's Famous Experiment and the Stroop Effect

- Describe Stroop's Famous Experiment and the Stroop Effect Strop Ridley wrote the article, known as the “Studies of Interference in Serial Verbal Reactions” in the year 1935. The article was based on a research that he conducted using colors to analyze the effects of interference on serial verbal reactions. The main objective of the research was establishing relationships between common changes in the environment and the reaction to these changes with respect to time (Stroop, 1935). In his study, Stroop developed a model that was meant to analyze the reaction by some students with regards to color identification and reading out words painted in different colors....   [tags: Psychology]

The Effect of Visual Field Position and Type of Stimuli on the Stroop Effect

- Abstract An experiment was conducted to test the effect of lateralization and congruency on reaction time to name colors. This was done using a computer program provided by The University of Mississippi. This effect is called the stroop effect. Results showed that it was neither lateralization nor congruency had a significant effect on reaction time, but the interaction of these two variables that created a significant change in the time needed to recognize colors. It is believed that this is due to the different hemispheric functions of the brain....   [tags: experiment with colors]

Investigating the Stroop Effect Essay examples

- Introduction: When a behavior or skill seems to no longer require direct interaction, cognitive psychologists say it is automatized. Many behaviors can become automatized: typing, reading, writing, bicycling, piano playing, driving, etc. Automatization is interesting because it is an important part of daily life. We perform a variety of automatized behaviors quickly and effortlessly. In some cases people report that they do not consciously know how the behavior is performed, they just will it to happen, and it does happen....   [tags: Stroop Effect]

The Stroop Effect Essay

- 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). In the study of the female chimpanzee Lana, the authors tested the Stroop-like effect with an animal to gather evidence from a nonverbal organism to provide additional information about the role of compatibility betwee...   [tags: Medical Research]

Stroop Effect: Color Wording and Cognitive Interference Essay

- The ability for adaptive behavior and the conditions that affect it has been a central area of research for psychologists since its inception. When behaviors are learned they become automatic processes. Automatic processes can be described as behavior that is not particularly motivated by the avoidance of error because a person no longer has to consciously think about the next piece of desired information. Automatic processes occur with less effort and error, whereas controlled processes need to occur with a person’s full attention....   [tags: Psychology]

Testing the Theory of Multitasking Essay

- This experimental investigation has to do with how human’s attention work. It is based on a replication of the well-known “Stroop Effect” carried out on 1935 by John Ridley Stroop. The aim of this experiment was to demonstrate how hard it is for a person’s attention to be divided in different tasks, by making the participants read a series of three stimuli which consisted of: 1) words of colors in black ink, 2) words of colors in their actual font color, and 3) color words with different ink, where the participant read the font instead of the word present....   [tags: Stroop Effect, Experimental Investigation]

Essay on The Stroop Effect: Revisited Through Nonarbitrary Key Press Modality

- In his article Stroop (1935) detailed the research before his own concerning interference (inhibition) which were centered on testing associative inhibition. Researchers were using sets of nonsense syllables (stimuli) that were assigned to be associated with a different set of nonsense syllables (response), and later the stimuli syllables were changed to be assigned with a completely different set of response syllables. Researchers found that once nonsense syllables (stimuli) became associated with a certain set of other nonsense syllables (response) it was very difficult to redirect that association (see Stroop 1935)....   [tags: behavioral science, psychology]

The Stroop Word-Color Test Essay

- Introduction: In this Stroop experiment we attempt to investigate the inference in perception by showing 20 participants a Stroop color model and a controlled black and white model and compare the reaction times of the two. Stroop investigated in interference in perception demonstrating perception is a dynamic process open to influence. The Stroop word-color test can be modified into other languages other than English, thereby demonstrating how the Stroop Effect "works" across a range of languages, i.e....   [tags: Experiment Analysis]

Verbal Reaction Times Experiment Essay

- This report aimed to replicate Stroop's (1935) experiment. Using the repeated measures design and a sample of 20 students, differences in verbal reaction times on two tests were observed. The one-tailed hypothesis predicted that it would take longer to say words in the Cc, this is the conflicting condition where the colour of the word differs from the colour that the word describes. It was found that, using the t-test for related data, this hypothesis could be accepted as the obtained value was much greater then the critical value....   [tags: Stroop 1935 experiment]
