The Stroop Effect
Attention : The effects of automatic and controlled processing

Abstract

The theory of attention was focused on within the experiment, using a modified version of the Stroop effect. The stroop effect suggests that automatic and controlled processing can conflict with each other making it difficult to focus on a particular task. Participants were asked to look at two sets of stimuli which contained words written in coloured ink, colour related words and neutral words. Participants were asked to say the colour of ink that the word was written in. The results of the experiment showed a significant effect on response times between both stimuli, providing further support to the Stroop effect.

Introduction

The environment around us contains

Controlled processing requires a large amount processing power and therefore requires a conscious effort (Attention) to focus on a task. The process of attention enables us to filter out unnecessary information required and focus on the information needed at that given time.

The benefit of automatic processing is that due to the limited resources it requires, it enables us to complete more than one task at a time.

Kahneman (as cited in Gross, 2005) suggests that some tasks (those that have been practised regularly) become automatic, requiring less processing capacity, therefore allowing other tasks to be completed. However as this process is automatic, it makes it difficult to switch off.

The Stroop experiment (as cited in Gross, 2005) required participants to look at a list of colour words such as ‘red’ . These words were not written in the corresponding colour for example ‘red’ was written in black ink. The task was to say the colour of ink for each word as quickly as possible. The results of Stroop’s study showed that participants found it difficult ‘switching off’ the automatic process of reading in order to identify the colour the word was written

This is a two tailed hypothesis The null hypothesis was that there would be no difference in the response times of the two conditions.

Method

Design

The experiment used a within participants design. The independent variable was the manipulation of colours and words. Two conditions were used. These were colour related stimuli where participants were shown a list of coloured words, the coloured ink did not match the associated word and the neutral word stimuli, where the same colours were presented however no association with the word was present. The dependant variable was the time taken in seconds to complete each condition.

Control conditions were put in place to reduce possible confounding variables. All of the participants received the same set of instructions. All participants completed both condition 1 and 2. The order of the conditions were alternated between participants to reduce any practice effect, and the same equipment was used for all participants.

    The interference between the controlled and the automatic processes was observed in the Stroop effect type experiment using two different conditions. The original Stroop effect experiment concluded that the participants will find it more difficult to complete the reading task of the words related to colour meaning in comparison to the reading task of non-colour related words. The result of Stroop experiment supported the notion that control and automatic processes can obstruct each other in certain tasks. In the current experiment, the two conditions in reading task were modified to make them look more visually similar. The result indicated that despite of visual similarities, the automatic processes interfered with control processes due to the colour related properties of the words in Stroop condition.…

    My science project is on the Stroop Effect. Basically it’s an effect on the human brain; we become confused from the effect. For example if someone was to give you a paper with names of colors and the colors weren’t the same as the word. They told you to read it aloud; you are probably going to have a hard time reading the words because of the effect. John Ridley Stroop is the man who named a color-word task after him, he is a cognitive psychologist. He was showing that you could interfere with attention. Different learners are affected differently; there are visual, auditory, and tactile learners. Usually the visual learners don’t have as much trouble. In 1935 John said that if you test different genders separately, it won’t make a difference. He did four different tests; one was to read the words, tell him the color, read them clock-wise, and read them counter-clockwise. When Ridley tested he only tested college students, he tested them their 1st, 2nd, 3rd, 4th, and before they graduated.…

    The famous “Stroop Effect” is so called after its founder, J.R.Stroop who discovered and reported this strange phenomenon in his Ph.D. thesis, which was published in 1935 (Desoto, 2001). The original Stroop test is psychological tests of a person’s mental energy, vitality and flexibility (Monahan, 2001) and over the years it has been revised and adapted, yet the basic principles remain constant. The test takes advantage of a person’s ability to read words more promptly and automatically than they can name colors. The Stroop effect occurs as people attempt to name the color of words that spell out a conflicting color, and with the Stroop test the…

    Why is that we cannot perceive everything what is within the range of our senses? Is it because our capacity is not up to the job or is it because our conscious mind would drift us straight into insanity ? There is no straightforward answer to that. However, it is known that the attention itself is not only the conscious one, but also as it seem sub-conscious one, which is responsible for the automatic interactions with the environment. There is no need to concentrate on breathing or reading at the stage of an healthy adult person. But once those processes were new and there was a time when they were fully conscious. This experiment zooms in on the clash between controlled and automatic attention processing.…

    My science fair project was based on the Stroop Effect. The Stroop Effect was discovered by J. Ridley Stroop in the 1930’s. The Stroop Effect says that when you read a color word with the same ink as its color word, it will be recognized and be identified easily. When you read a color word with a different ink than its color word, it will not be recognized as easily. So you should be able to read the same color word with the same color ink faster than a color word with a different color ink. My purpose is to disprove the Stroop Effect so the question is, is the Stroop Effect true or not?…

    How the mind sees it and its reaction to seeing the colors. “ The first test is easy because the color and meaning of the word are congruent. There is no conflict.The second test is hard because the color and meaning of the word are incongruent. This creates a conflict that the brain has to resolve.The reason why it takes longer is because the brain has to suppress the wrong answer that interferes with the right answer, before the right answer comes through.” https://www.math.unt.edu/~tam/SelfTests/StroopEffects.html . For instance the brain creates a conflict that it has to resolve. “ The first test is easy because the color and meaning of the word are congruent. There is no conflict.The second test is hard because the color and meaning of the word are incongruent. This creates a conflict that the brain has to resolve.The reason why it takes longer is because the brain has to suppress the wrong answer that interferes with the right answer, before the right answer comes through.” ( Para.1) What do the colors do in the stroop effect. “The above demonstration does not even take into account the incorrect responses in naming the colors. If you let the wrong answer to slip through impulsively, without waiting for the right answer to come through, it's because the brain does not have enough inhibition to suppress the wrong choice.”…

    When reading a specific word, experienced readers know what the word is instantaneously, the name and meaning of the word come readers extremely fast. In most cases it is actually difficult to look at a word and not know its meaning. When looking at a word printed in a certain colour it is difficult to simply state the printed colour and ignore the colour that is actually written; the meaning of the word. This phenomenon is known as the Stroop effect. It shows that even when we try to ignore a well known memory it automatically gets retrieved. If the word meaning and colour are the same then facilitation appears; this results in a faster reaction time than compared to when the word meaning and colour are different,…

    On arrival, participants and the two observers entered the room and had the participant sit down in front of a desk. Participants received instructions orally and were asked if they had any questions before we continued with the experiment. The instructions listed each participant to name the shape of each item and avoid reading the word within the shape. Participants were asked to begin at the top left corner of the page and move left-to-right, row by row. In congruent shape trials, each shape matched the word within the shape. In incongruent shape trials, the shapes did not match the word within the shape. They were asked to repeat this task six times. Additionally, to control order effects, we counterbalanced the experiment by alternating trials for each condition. The condition that was tested first was the congruent trial, followed by the incongruent trial and it kept alternating in this manner. It was asked that participants should not hold the paper but were allowed to point at the paper on the table with their fingers. If participants felt stuck, they were instructed they may “skip” and move to the next shape. When the participant finished each task, the observer was to record the seconds it took for participant to finish naming the shapes. For each of the fifty-eight participants, their three congruent and three incongruent scores were to be averaged…

    The materials I used in this experiment were 8 people (subjects) and 8 clothespins of the same type. First I recognized my dependent variable, how many times you can squeeze clothespin, and my independent, exercise. I took a group of 8 classmates, excluding myself and instead including my younger brother. I decided to let the control group also serve as the experimental group. The steps I took were to let the control group rest before starting, and then they squeezed the clothespin for one minute and counted how many times they could squeeze it. After that they rested for another minute, then exercised by jogging in place for one minute and after they immediately squeezed the clothespin.…
