A variation of the stroop effect

Brown Green Blue Green Stimulus 3: Names of colors appeared in black ink: Names of colors in a different ink than the color named; and Squares of a given color. 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. 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 reda process that is not automated.

Neutral stimuli are those stimuli in which only the text similarly to stimuli 1 of Stroop's experimentor 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.

It has been sometimes called Stroop asynchrony, and has been explained by a reduced automatization when naming colors compared to reading words. 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.

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.

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.

Processing speed[ edit ] This 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.One such variation is the reverse Stroop test.(Wikipedia) In this experiment there were still two conditions; one where the participant was given a list of colour words and had to point to a block of colour which matched the colour word stated.

Stroop Effect CogLab Report Stroop Effect CogLab Report The Stroop effect is a test that demonstrates a decrease in reaction time that occurs when the brain receives conflicting information. When sensory information conflicts, a processing delay occurs in the brain; this is interference.

In psychology, the Stroop effect is a demonstration of interference in the reaction time of a task.. When the name of a color (e.g., "blue", "green", or "red") is printed in a color which is not denoted by the name (i.e., the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the MeSH: D Through a variation of the Stroop effect, the present experiment investigated further the idea that automatic processing interferes with the information a person is consciously trying to attend.

This study was an investigation of the cognitive processes at work during a variation of the classic Stroop test and effect, in which the degree of intrusion into automatic thought processes may be witnessed in a colour identification task. The famous "Stroop Effect" is named after J.

Ridley Stroop who discovered this strange phenomenon in the s. Here is your job: name the colors of the following words. Do NOT read the words rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should.
