Tes Stroop Effect : Tes Psikologi Kemampuan Multitasking

The effect has been used to create a psychological test the Stroop test that is widely used in clinical practice and investigation. A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color e. When asked to name the color of the word it takes longer and is more prone to errors when the color of the ink does not match the name of the color. The effect is named after John Ridley Stroop , who first published the effect in English in Examples of the three stimuli and colors used for each of the activities of the original Stroop article.

The effect was named after John Ridley Stroop , who published the effect in English in in an article in the Journal of Experimental Psychology entitled "Studies of interference in serial verbal reactions" that includes three different experiments. In his experiments, Stroop administered several variations of the same test for which three different kinds of stimuli were created: Names of colors appeared in black ink; Names of colors in a different ink than the color named; and Squares of a given color. In the first experiment, words and conflict-words were used see first figure. The task required the participants to read the written color names of the words independently of the color of the ink for example, they would have to read "purple" no matter what the color of the font.

In experiment 2, stimulus conflict-words and color patches were used, and participants were required to say the ink-color of the letters independently of the written word with the second kind of stimulus and also name the color of the patches. If the word "purple" was written in red font, they would have to say "red", rather than "purple". When the squares were shown, the participant spoke the name of the color. Stroop, in the third experiment, tested his participants at different stages of practice at the tasks and stimuli used in the first and second experiments, examining learning effects.

Unlike researchers now using the test for psychological evaluation, [5] Stroop used only the three basic scores, rather than more complex derivative scoring procedures. Stroop noted that participants took significantly longer to complete the color reading in the second task than they had taken to name the colors of the squares in Experiment 2. This delay had not appeared in the first experiment. Such interference were explained by the automation of reading, where the mind automatically determines the semantic meaning of the word it reads the word "red" and thinks of the color "red" , and then must intentionally check itself and identify instead the color of the word the ink is a color other than red , a process that is not automated.

Stimuli in Stroop paradigms can be divided into 3 groups: neutral, congruent and incongruent. Neutral stimuli are those stimuli in which only the text similarly to stimuli 1 of Stroop's experiment , or color similarly to stimuli 3 of Stroop's experiment are displayed. Incongruent stimuli are those in which ink color and word differ. It is called semantic interference since it is usually accepted that the relationship in meaning between ink color and word is at the root of the interference. The third finding is that both semantic interference and facilitation disappear when the task consists of reading the word instead of naming the ink color.

It has been sometimes called Stroop asynchrony , and has been explained by a reduced automatization when naming colors compared to reading words. In the study of interference theory , the most commonly used procedure has been similar to Stroop's second experiment, in which subjects were tested on naming colors of incompatible words and of control patches. The first experiment in Stroop's study reading words in black versus incongruent colors has been discussed less. In both cases, the interference score is expressed as the difference between the times needed to read each of the two types of cards. Brain imaging techniques including magnetic resonance imaging MRI , functional magnetic resonance imaging fMRI , and positron emission tomography PET have shown that there are two main areas in the brain that are involved in the processing of the Stroop task.

The posterior dorsolateral prefrontal cortex creates the appropriate rules for the brain to accomplish the current goal. Next, the mid-dorsolateral prefrontal cortex selects the representation that will fulfil the goal. The relevant information must be separated from irrelevant information in the task; thus, the focus is placed on the ink color and not the word. Conversely, the right dorsolateral prefrontal cortex aims to reduce the attentional conflict and is activated after the conflict is over. Moreover, the posterior dorsal anterior cingulate cortex is responsible for what decision is made i.

Activity in this region increases when the probability of an error is higher. This is based on the underlying notion that both relevant and irrelevant information are processed in parallel, but "race" to enter the single central processor during response selection. This theory, also called Relative Speed of Processing Theory, suggests there is a lag in the brain's ability to recognize the color of the word since the brain reads words faster than it recognizes colors.

In a condition where there is a conflict regarding words and colors e. Conversely, if the task is to report the word, because color information lags after word information, a decision can be made ahead of the conflicting information. The Selective Attention Theory suggests that color recognition, as opposed to reading a word, requires more attention. The brain needs to use more attention to recognize a color than to encode a word, so it takes a little longer. This may be a result of either an allocation of attention to the responses or to a greater inhibition of distractors that are not appropriate responses.

This theory is the most common theory of the Stroop effect. This idea is based on the premise that automatic reading does not need controlled attention, but still uses enough attentional resources to reduce the amount of attention accessible for color information processing. He demonstrated that changing the responses from colored words to letters that were not part of the colored words increased reaction time while reducing Stroop interference. This theory suggests that as the brain analyzes information, different and specific pathways are developed for different tasks. In the neo-Piagetian theories of cognitive development , several variations of the Stroop task have been used to study the relations between speed of processing and executive functions with working memory and cognitive development in various domains.

This research shows that reaction time to Stroop tasks decreases systematically from early childhood through early adulthood. Neurologically there could be involvement of the dorsolateral prefrontal cortex, as well as the Anterior cingulate cortex , which is thought to be responsible for conflict monitoring. The Simon Effect shows that location information cannot be ignored and will affect decision making, even if the participant knows that the information is irrelevant. The challenge in the Simon effect is said to occur during the response selection stage of judgment. This is due to two factors which eliminate the stimulus identification stage and the execution state.

In the stimulus identification stage the participant only needs to be cognitively aware that a stimulus is present. An error would not occur at this stage unless he or she were visually impaired or had some sort of stimulus deficit. As well, an error or delay cannot occur during the execution state because an action has already been decided upon in the previous stage the response selection stage and no further decision making takes place i. A knowledge of the Simon effect is useful in the design of human-machine interfaces. Aircraft cockpits, for example, require a person to react quickly to a situation. If a pilot is flying a plane and there is a problem with the left engine, an aircraft with a good human-machine interface design which most have would position the indicator light for the left engine to the left of the indicator light for the right engine.

This interface would display information in a way that matches the types of responses that people should make. If it were the other way around, the pilot might be more likely to respond incorrectly and adjust the wrong engine. From Wikipedia, the free encyclopedia. Such interference was explained by the automation of reading, where the mind automatically determines the semantic meaning of the word, and then must override this first impression with the identification of the color of the word, a process which is not automatized. As opposed to the Stroop test most commonly used in psychological evaluation, [5] J. R Stroop never compared the time used for reading black words and the time needed for naming colors that conflicted with the written word.

The original paper of the Stroop effect has been one of the most cited papers in the history of experimental psychology , leading to over replications. In the study of interference the most commonly used procedure has been similar to Stroop's second experiment, in which subjects are tested on naming colors of incompatible words and of control patches; however the first experiment reading words in black versus incongruent colors has received much less interest. In both cases the interference score is expressed as the difference between the times needed to read each of the two types of cards. The Stroop task has been employed to study frontal function and attention in brain imaging studies.

For instance, three words may be displayed that read "two" and the participant must press three on their button box. The test has additionally been modified to include other sensory modalities and variables, [8] to study the effect of bilingualism , [9] or to investigate the effect of emotions on interference. If a number or letter is presented to such an individual in a color other than what they would perceive, there is a delay in determining what color the character actually is. Since its development, the Stroop task, a measure of the effect of interference on performance of a color identification task, has utilized the Stroop effect to investigate aspects of such varied psychological disorders as Attention Deficit Hyperactivity Disorder , Schizophrenia , and Anorexia.

EEG and fMRI studies of the Stroop effect have revealed selective activation of the anterior cingulate cortex during a stroop task, a prefrontal structure see frontal lobe in the brain which is hypothesized to be responsible for conflict monitoring. Edith Kaplan 's group developer of the Delis-Kaplan neuropsychological test battery developed the task further by separating the task into four different stages: naming color fields, congruent color words, incongruent color words, and combined.

The additional strain on the executive function of the brain allows for a more precise diagnosis. Psychology Wiki Explore.
