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. it is cross-cultural.
In the traditional Stroop effect, naming the print color of a word is delayed if the word itself is a color word which names a different color (e.g., responding "red" to the word "blue" displayed in red letters is

Word colour incongruence will not slow word recognition.
Method: Design:
The variables we are presented with in this experiment are a dependent variable, and independent variable, and a controlled variable. The independent variable is the interference in perception put to use by changing the color of the words. The dependent variable is the processing and this is put to use by the time taken to read the words.
There are no ethical considerations in this experiment because all participants were debriefed and signed a consent form, and no psychological or physical harm was done.
Participants:
The target population was 11th graders and teachers from UNIS (The United Nations International School in Hanoi). The participants come from all different parts of the world to ensure diversity and eliminate any cultural bias or concerns. The participants were both male and female and their ages ranged from 16 to 45. This sample was an opportunity sample because it was the most convenient and hassle free method of collecting data in the amount of time we had.

In another study, five experiments were conducted to determine if coloring a single Stroop element reduced automaticity or slowed the processing of a color. The results demonstrated that indeed it slowed processing of congruent and neutral stimuli more than it slows processing of incongruent stimuli (Monahan, 2001).
An interesting challenge arises when a task such as color naming is identified as both controlled and automatic, by varying the other task involved. Color naming is identified as a controlled process when the other task is word reading, but as an automatic process when the other task is shape naming. Cohen, Dunbar and McClelland (1990) proposed an alternative explanation of the Stroop effect, which does not distinguish between automatic and controlled processing. Instead, they proposed that automaticity is a range, and that Stroop interference depends on the relative degree of learning the particular tasks, not on processing speed.
The Stroop effect was tested on four different tasks. Nineteen Queens College students were recruited by flyer, and each were assigned to a word reading task, color reading task, color inhibition task, and word inhibition task. They were timed using a stopwatch function on a cell phone, to name the color, or word to the quickest of their ability. In the order from longest reaction time to shortest: inhibition color naming task, color naming task, inhibition word reading, and word reading. This study shows that people can read words more quickly than they can name colors, and that inhibiting an automatic response to color/word tasks will take longer to do than tasks that do not involve inhibition.
The Stroop experiment by J. Ridley Stroop in 1935 was performed in order to analyze the reaction time of participant’s stimuli and desired results while also obtaining a collective result of color interference and word reading(Stroop, 1935; Lee & Chan, 2000). In the experiment three forms of the test were given, the first consisting of color patches, the second had the color words printed in black and the other was an incongruent test beaming the color did not match the color word
This study examined visual perception and the rates at which global and local features are reacted to with an aim of replicating and validating a previous experiment conducted by Navon (1977) to see if global processing was faster than local processing. There was 222 University of Newcastle students participating in the experiment, partaking in two phases, one centred round global processing, the other around local processing, where there reaction times were recorded using a computer program and imputed into a data worksheet. Results indicated that, as predicted, global processing occurred at a faster rate than local processing. It was concluded that global features were
The Stroop test consisted two major posters of word lists: Incongruent list and Neutral list. Each poster included 20 words in 2 columns of 10 words each. All letters were stenciled, capitalized and 1 ¾ inches high. Both incongruent and neutral words were listed on the 56 x 71 cm posters Stopwatch with 0.01-second accuracy was used to time to measure how long participants took to read both incongruent and neutral word lists, which is a dependent variable for this experiment.
In Stroop’s (1935) interference article, it was discovered that there is more interference in color naming then color reading. The experiment described in the article tested whether there was more interference from words or from colors (Stroop 1935). Two tests were administered each with a separate control. The RCNd test determined how fast one could read color names where the color was different from the color name while the NCWd test determined how fast one could name colors where the color was different from the word on the page. The mean time for 100 responses increased from 63.3 seconds on the RCNd test to 110.3 seconds on the NCWd test or an
In the Stroop (1935) experiment he has proved that the effect is going to be one of the two slower or faster. In the non-conflict, some of the participants had to read two sets of words: set one with word written in their contradicting word so this has made it to be conflicting. Stroop (1935) came out to find that there are different association of words and the colors. Stroop (1935) wanted to see if they had any differences in the reaction time when the association was conducted. He noticed that the participants took longer read the conflicting word rather than the actual name word. The non-conflict was much easier and faster to do.
In the Stroop task, participants are asked to name the colour of the ink that a colour word is written in, while ignoring the written the word (Goldfarb et al., 2011; Raz et al., 2006). The task is comprised of congruent words, where the ink colour and the written word match and incongruent words, where the ink colour and the written word do not match. The Stroop task has illustrated that participants respond slower and less accurately when the word is incongruent compared to when it is congruent (Goldfarb et al., 2011; Raz et al., 2006). The difference in the accuracy and speed of responses between the congruent and incongruent words is called the Stroop Effect (Goldfarb et al., 2011; Raz et al., 2006). Research has suggested that this occurs
The participants were presented with stimuli of two components which was displayed to them on screen. One stimuli was the coloured rectangular patch (3.5x5.5cm). This patch was presented in a variety of difference colours; yellow, red, green and blue. The other stimuli that was presented to the participants was a word, which either matched up to one of the four colours, however could have been in-congruent or congruent or a natural, control 'word ' being XXXXX. As well being presented with the patch, the words would also appear, in size 24, in the centre of the patch. There were four conditions for when the word appeared; 0ms (simultaneously), 100ms, 200ms or 350ms.
Study examined the Stroop effect in words which are not colours, but represent related object connected to certain colours and whether that would yield similar or the same effect as the classic Stroop study. Previous studies such as Stroop's (1935) found out a clash between controlled and automatic processing, which resulted in delayed answering. This experiment was conducted for 20 participants of both sexes and various age categories. They were given two lists consisting each of 30 coloured words. One half of these words were colour-neutral and other colour-relevant. As was expected, the colour-neutral were processed much faster. It is therefore
In the Stroop task 8 college student participants from a cognitive lab course. Two participants were males and the remaining 6 participants were female. Using a computerized program Cedrus SuperLab 4.5 the participants were tested in the Stroop Task. The participants were asked to identify four colors, blue, green, red or yellow. In addition, participants were also asked to identify the names of the colors they saw by pressing a corresponding computer key with their middle and index fingers, D for red, F for blue, J for green, and K for yellow. Our experiment was conducted in two phases a practice phase and a testing phase.
The stroop effect is a strange phenomenon when your right and left side of your brain have a conflict about what the word says and what color the word is. I am going to make a project to examine everyone’s attempt and graph it. I am going to see if the difficulty is harder or easier compared to the age and gender of the challengers.
In his historic study, Stroop found that reading names of colors interfered with individuals’ ability to name the ink color the word was printed in when the two differed (i.e., the word “BLUE” written in red ink) (1935). However, the basis of this phenomenon can be traced back to Cattell who found that naming colors and pictures took twice as long to accomplish than reading the word these colors or pictures represented (1886). He concluded that this was due to reading being an automatic process while identifying colors or pictures requires a conscious effort (Cattell, 1886). MacLeod (1991) reflects that it was Cattell’s work which strongly influenced future psychologist including Stroop.
We are replicating J.R. Stroop’s original experiment The Stroop Effect (Stroop, 1935). The aim of the study was to understand how automatic processing interferes with attempts to attend to sensory information. The independent variable of our experiment was the three conditions, the congruent words, the incongruent words, and the colored squares, and the dependent variable was the time that it took participants to state the ink color of the list of words in each condition. We used repeated measures for the experiment in order to avoid influence of extraneous variables. The participants were 16-17 years of age from Garland High School. The participants will be timed on how long it takes them to say the color of the squares and the color of the words. The research was conducted in the Math Studies class. The participants were aged 16-17 and were students at Garland High School. The results showed that participants took the most time with the incongruent words.
