Stroop Effect Theory

1625 Words7 Pages

Introduction Human reaction time is a measurement of the time it takes a person to react mentally and physically to a stimulus. The concept has been extensively studied due to the great inconsistency in reaction time in different situations. The reason for this has been called interference as some variable interferes with a person’s ability to efficiently and appropriately responds to a stimulus. A psychologist that studied this is J. R. Stroop, the man behind the theory of the Stroop effect. The Stroop effect demonstrates that reaction time is longer for naming ink colour of a word than it is for reading the word itself. This is, arguably, due to parallel processing, which complicates multitasking. Parallel processing is simultaneous processing …show more content…

compared in congruent and incongruent wordlist Discussion J. R. Stroop (1935) in his study found that reaction time for reading words where colour is absent (words written in black ink), naming colours where words are absent, and reading words in colour had shorter reaction time than naming colours when words were present. My study, that was a condensed form of the Stroop experiment, got similar results. I found that reading words where colour is absent and reading words in colour have a significant difference. Reading words where colour is absent (condition 1) takes less time than condition 2; where the participant have to name the colour of the words. This indicates that there is a distinction between controlled and automatic processing. The average difference in time in seconds between the two conditions was 5.29 (≈ 5.288), which demonstrates a significant difference. Furthermore, the scores of both the conditions occurred closed to their means, due to the standard deviations, which were …show more content…

For this experiment, I had decided to not ask the participants about their eyesight due to ethical concerns. After the third and first male participants told us about his colour-blindness I decided to ask the following participants. For future experiment, in order to improve the study, I would ask all participants whether they have some degree of colour blindness in order to eliminate that confounding variable. The ethical implications of this may be discomfort for the participant; however, they have the right to withdraw from the experiment at any time during the experiment if they so wish

The Stroop Effect and the Horse Race Model Phenomena Rochelle Hall City University of New York- Brooklyn College Abstract Introduction The Stroop test phenomena was first introduced to the world of Experimental Psychology by J.R. Stroop in the year 1935. This landmark article has since influenced the research and publication of over 700 other Stroop-related articles. MacLeod (1991, p. 163).

Stroop Effect Essay

1597 Words | 7 Pages

The Stroop effect was established by John Ridley Stroop in 1935 and has since become increasingly influential through its replication in published works. This effect illustrates the interference in human perception (Hilbert, Nakagawa, Bindl, & Buhner, 2014) and is a perfect example that describes situations in which task-irrelevant stimuli are hard to ignore. This study aims to investigate whether the fast and automatic processing of the colour denoted by a word will interfere with the ability to identify the font colour of the word. According to Raz, Moreno-Iniguez, Martin and Zhu (2007), Stroop effect is the difference in response time between congruent and incongruent stimuli – increase in time taken to name the font colour when it differs from the colour denoted by the word

Jane Elliott's Argument Analysis: The Blue Eyed Experiment

The blue eyed – brown eyed experiment in my opinion is indeed ethical. The issue at hand with this experiment is will it cause permeant future psychological damage. Jane Elliott conducted this experiment with her third-grade students which some would say it is too harsh of an exercise for a group that young; She wanted to teach her student that discrimination is wrong which have been a topic they discussed from the first day of school but felt the student would become confused with the fact she just honored Dr. king in the month of February and now she had to explain to them that he was assassinated because of discrimination. Jane Elliott agreed that this exercise can do Psychological damage if not conducted correctly but the benefits are remarkable.

Stroop Experiment

220 Words | 1 Pages

The study of the link between automated operations and inhibition has been seen by psychology scholars as one of strong importance over time. John Ridley Stroop (1935) demonstrated that a automated operation like reading words interference the execution of not automated actions. In the experiment conducted by Stroop, participants read words denoting colors (eg. Red,Yellow and Green). Regardless of what color that was written; when participants had mentioned the colour which was the written word, they did more slowly when the word "red" was written in "green" and quickly when the word "green" was written in green, ignoring ink color reduces the speed of reading.

The Stroop Effect

Due to the results from the first experiment being insignificant Stroop conducted a second experiment that was slightly different. Participants were told to name colours rather than read words. There were again two conditions, the first condition participants said the colour of the coloured square and in the second conditions the participants read a word list printed in incongruent colours and said the colour of the ink and not the word. The results show that many participants took longer to do the second condition compared to the first. Many participants made more mistakes doing the second list as they were saying the word not the ink colour.

To gain a better understanding of how the brain processes and encodes data when dealing with interference, facilitation, and automaticity of a stimulus in the Stroop effect, I performed an experiment using the numerical Stroop effect. With the help of the 114 Florida Atlantic University students, we performed a within-test subject design and measured the reaction time in seconds of our participants based on the four types of conditions: neutral naming, neutral counting, congruent and incongruent. Neutral naming had the fastest reaction time which followed by congruent, neutral counting, and incongruent. Significant differences were found between congruent and incongruent conditions in reaction time as well as in neutral counting and neutral

The Stroop's The Stroop Effect

148 Words | 1 Pages

Named after John Ridley Stroop, the Stroop Effect demonstrates that people read words more quickly and automatically than they can name colors (De Young). A very common way to test this is to have multiple subjects read a series of colors that are written in a different color ink. For example, if the word is blue, but is written in a green ink, green would be said allowed. If this is the case, then will the subject read the word with the same color ink faster than the words with different colored ink?

While each subject was confirmed to read all of the incongruent words at a much sluggish paste. Therefor the subjects seem to read better, faster, and more efficiently, when reading congruent words than subjects reading incongruent words tend to read sluggish, incorrectly, and difficulty. This all was proven by John Ridley Stroop. This middle age man, (76 years old) was was the founder of the Stroop Effect.

Mental Rotation Experiment Essay

Although the accuracy was part of the measurement, the data analyzed only includes reaction time. Therefore, the similar average reaction time between male and female could be due to the difference in accuracy. For example, fast reaction time could have easily been achieved by continuously pressing the same response for every trail. Consequently, the reaction time would be as fast, but the accuracy would be very low. However the finding will not have reflected this important factor.

Stroop Effect Experiment

The aim of this experiment was to investigate the efficiency of the Stroop Effect by making a partial replication on J.R. Stroop’s original experiment (Stroop, 1935).The independent variable of our experiment was the two conditions, the congruent and the incongruent conditions, where the list of words remained in black in the congruent whereas the list of words were printed in a variety of colours in the incongruent condition. The dependent variable was the time that it took participants to state the ink colour of the list of words in each condition. This experiment used “repeated measures” for the experiment in order to avoid influence of extraneous variables, and the 21 participants from an International School in Malaysia who were selected by convenience sampling, were presented with the
