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).

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.

The Stroop Effect

The aim of the experiments was to demonstrate interference in serial verbal reactions with time taken to do a task. Seventy (14 males and 56 females) college undergraduates took part in the experiments. There were two different conditions in the first condition the participants read words printed in black and the second condition participants read colour word that was printed in a different colour. The results of this experiment show that there was no significant different in the time taken to read the words in the two conditions. Stroop hypothesis was that response time between stimulus and response will be longer when the font name and colour are different.

Essay On Stroop Interference

It took them longer to block out the reading process so they can name the color. From these results I can conclude that if the word has a similarity to the color, has an effect on the time it takes to identify the color. A notice a few factors that also had an effect on the amount of Stroop interference. The main a factor that I saw was if the shade of colors were very similar it really slowed the participant’s type down. This was clear on the modified list on items four, the word was brown and it was colored black.

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

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?

Likewise, Cohen and his colleagues also restructured Stroops experiment, with a focus on aging while also employing a computerized version of the test. Our experiment conducted in class is recognized as a replication study, as it ultimately reproduces the Stroop experiment. The particular purpose of our study was to examine the interference effect, and in order to accomplish this we used Stroop Application Testing. The interference effect occurs when previously knowledge interferes with current task

Which causes your brain to slow down by a great amount. Currently, on average it takes females 0.18 seconds to finish reading ten congruent words, and it takes females on average 0.27 seconds to finish reading ten incongruent words. On the other hand it takes men on average 0.30 seconds to finish reading ten congruent words, and it takes males on average 1.04 long to finish reading ten incongruent words. During this test each subject was given instructions to read each word, and only the word, this was the test for congruent. Each subject was proven to read all of the congruent words at a swift paste.

On the other hand, non-words do not have meaning, so their semantic representation are not a problem. In the case of the pseudohomophone condition, a sound based representation is required since the words' meaning do not correspond to colors. These semantic representations can be manipulated if the subject do not pay attention at the word itself and try to see it as a colored object. In fact, this would be the ideal strategy to complete the experiments accurately. If successfully accomplished, this goes against the idea that reading is an automatic process and the semantic activation cannot be

Secondly, because the experiment was conducted online, it is not clear whether the participants actually read and followed the instructions. Prior to the trails, the instructions reminded the participants that “accuracy is more important than speed”. It is possible that the participants missed the instructions and tried to strive for better reaction times rather than accuracy. In addition, the sample size was relatively small compared to the previous experiments which could be another confounding factor. One possible direction for future study is to examine the effects of different visual stimuli used on the performance of MRT.
