Serial Verbal Response

In experiment 1, participants were instructed to press a key to determine if the stimulus was red, blue, yellow, or green. On the second half of the experiment, the stimulus appeared in grey with only one colored letter which was positioned randomly. Error rates for the experiment were below 2.5% for each condition, which is quite low. Experiment 2 was the same as experiment 1 except that there were 114 data collections instead of 288 and there were 36 practice trials instead of 72. According to experiment 1 and 2 it is suggested that the effect of

The Stroop (1935) effect is the inability to ignore a color word when the task is to report the ink color of that word (i.e., to say "green" to the word RED in green ink). The present study investigated whether object-based processing contributes to the Stroop effect. According to this view, observers are unable to ignore irrelevant features of an attended object (Kahneman & Henik, 1981). In three experiments, participants had to name the color of one of two superimposed rectangles and to ignore words that appeared in the relevant object, in the irrelevant object, or in the background. The words were congruent,

The aim of the present study is to find out whether engaging in tasks involving words, colors, and inhibition word and color tasks would significantly differ in response times.

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

The experiment used the same red and green stimuli in each trial instead of other opponent colors such as black and white or blue and yellow. The small sample size studied could have also lead to random variation in the results.

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

This experiment investigated the Stroop effect comparing response times between naming colour ink printed in colour-associated words and colour neutral words. Previous research of two-process theories which support Stroop's studies [cited in Edgar:2007] found that automatic processes can interfere with controlled processes. To test this interference further, colour-associated words were employed. Results of this experiment show a statistically significant difference in condition response times, with naming the colour ink printed in colour-associated words taking longer than those in colour

Limitations are demand characteristics and that is why we used non-psychology students in order to reduce this variable. The independent variable was the color stimuli. In the control congruent words test, the color stimulus was color words all printed in black. In the incongruent words test the color stimulus was colored words printed in different colors to what they are written as ( Blue written in red ink). The dependent variable was the time it took the participants to name the colors. During the incongruent word test, participants were not allowed to leave any error

The first study consisted of 115 participants. They were split into three groups and were given anagrams to solve. The independent variable was the color of ink the instructions appeared: red, green, or black. The dependent variables were the participants answers to a questionnaire consisting of six questions and the number of correct anagrams they solved. The results indicated that the researcher’s hypothesis, that participants given instructions in red ink would perform worse, was supported.

My experiment was performed as a replication of a previous experiment by Stroop (1935). J. R. Stroop (1935) conducted this experiment as a means to study interference by using task-irrelevant stimuli. Task-irrelevant stimuli are stimuli that are unrelated to the current task (Goldstein, 2011). Interference is the competition of responses (Goldstein, 2011). The effect that was found was later named the Stroop Effect (Goldstein, 2011).

1. The authors decided to do a replication of a study performed by of Ramachandran & Hubbard (2001) and Hubbard (2005). From this study researchers looked at individuals who had synaesthetes and how they interpreted shapes, numbers and colors. Results from their study showed that individuals who had synaesthetes performed better by interpreting certain pictures by using more of the ‘pop-out’ effect rather than using the serial search effect. It also “assumed that color and shapes are processed independently, which does not hold true for people who have synathecia, giving that some amount of grapheme processing must be required for the color to be included”(Ramachandran & Hubbard 2001b, 2003b). Due to these findings researchers decided to “correct”

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 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

ABSTRACT: This investigation entailed the study of wether gender will affect the reaction times when tested. The average visual reaction time for a human is 0.25 seconds (250 milliseconds) and the average touch reception is 0.15 seconds (150 milliseconds), adding both these figures gives and estimated group time of 0.40 seconds (400 milliseconds). The average reaction speed for the boys was 342 and the average reaction speed for the girls was 392, in relation to average reaction speed these results are quite accurate as the age bracket was younger and smaller than the expected averages for humans.This investigation is well related to society as the measurement of visual reaction time has been used to evaluate the processing speed of Central Nervous System and the co-ordination between the sensory and motor systems, when shown a visual stimulus.

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.
