What are common parameters for the Eriksen flanker task?

What does Eriksen Flanker test measures?

In cognitive psychology, the Eriksen flanker task is a set of response inhibition tests used to assess the ability to suppress responses that are inappropriate in a particular context.

What is the point of a flanker task?

The flanker task allows for testing of both voluntary and nonvoluntary attention, by giving subjects either correct or incorrect information about the flank on which the target stimulus will appear (Figure 8.28). This can be varied from trial to trial.

How long does flanker task last?

The setup for the Flanker task is straightforward. In each trial, the stimulus is shown for unlimited time until the participant responds to advance to the next trial. Stimuli in Flanker tasks are typically composed of a target image in the center which is flanked by one or more distractor stimuli on either side.

What is the role of distractors in a flanker compatibility task?

In other words, we can ignore distracting information when the relevant information is easy to process, but cannot ignore it when the relevant information is more difficult to process.

How do you administer a flanker task?

The direction of the arrow in the middle if the middle arrow is pointing to the left. They press the left button if it's pointing to the right they press the right button.

What is the accuracy in congruent flanker trials?

Third, for the flanker task the accuracy for incongruent trials that are preceded by congruent trials obtained with the fastest RT bin is 26.2%, which is well below chance level, T(41) = 3.81, p < . 001.

What is the flanker compatibility effect?

Abstract. When subjects must respond to a relevant center letter and ignore irrelevant flanking letters, the identities of the flankers produce a response compatibility effect, indicating that they are processed semantically at least to some extent.

What is the accuracy in congruent flanker trials?

Third, for the flanker task the accuracy for incongruent trials that are preceded by congruent trials obtained with the fastest RT bin is 26.2%, which is well below chance level, T(41) = 3.81, p < . 001.

What does flanker mean in psychology?

a task in which stimuli are assigned one of two responses and the participant is required to respond to the target stimulus when this is flanked by other stimuli.

What is the role of distractors in a flanker compatibility task?

In other words, we can ignore distracting information when the relevant information is easy to process, but cannot ignore it when the relevant information is more difficult to process.

How is flanker effect calculated?

We calculated two interference scores for the Flanker task: (1) subtracting the mean RT for the correct congruent items from the mean RT for the correct incongruent items within the combination condition and (2) subtracting the mean accuracy for the congruent items from the mean accuracy for the incongruent items …

What does the Stroop test measure?

The Stroop Color and Word Test (SCWT) is a neuropsychological test extensively used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute, well-known as the Stroop Effect.

How do you administer the Stroop test?

You can do this three ways:

  1. press the relevant button at the bottom of the screen.
  2. press the following keys: r for red, g for green, b for blue, y for yellow, o for orange, or p for purple.
  3. press the following keys: a for red, f for green, j for blue, ; for yellow, x for orange, or m for purple.


What does Stroop effect prove?

The Stroop effect is a simple phenomenon that reveals a lot about how the how the brain processes information. First described in the 1930s by psychologist John Ridley Stroop, the Stroop effect is our tendency to experience difficulty naming a physical color when it is used to spell the name of a different color.

How do I reference the Stroop task?

What is a good Stroop score?

The Stroop can be used on both children and adults (Grade 2 through adult), and testing can be done in approximately 5 minutes. Word, color, and color-word T-Scores of 40 or less are considered “low.” Word, color, and color-word T-Scores above 40 or are considered “normal.”

How do you administer the Stroop color-word test?

Are on this page i want you to name the color of the ink the words are printed in ignoring the word that is printed for each item. For example point to the first item of the first column.

What was the dependent variable in the Stroop experiment?

In a Stroop effect experiment, this would be the colors of the words. Dependent variable: The part of an experiment that’s measured. In a Stroop effect experiment, it would be reaction times.

What is the level of independent variable?

Levels of an Independent Variable



If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control.

What is one reason why the Stroop effect occurs?

There are two theories that may explain the Stroop effect: Speed of Processing Theory: the interference occurs because words are read faster than colors are named. Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words.

What do the terms congruent and incongruent mean in terms of the Stroop effect?

Congruent stimuli are color-words that are written in the same ink color as the word (i.e., “blue” written in blue ink), whereas incongruent stimuli are those that are written in an ink color that does not match the color-word (i.e., “blue” written in red ink).

What are the factors affecting the Stroop effect?

With respect to the Stroop effect, it is likely that several factors are involved, including non-specific performance effects of practice (e.g., stimulus encoding, response execution, & color name facility) that impact both control as well as interference conditions.

What is congruent task?

One common tool to assess cognitive control is the Stroop Task. This task requires individuals to inhibition an overlearned, more automatic response, and instead provides an incongruent answer—do not read a color word (e.g., red) and instead name the color of the printed ink.

How would the performance on a Stroop task differ between an adult and a 4 year old?

Children responded slower than adults and made more errors on each task. Contrary to some previous studies, interference (the difference between neutral and incongruent condition) showed no reaction time (RT) differences by group or task, although there were differences in errors.

How does the Stroop test change with healthy aging?

Older adults have demonstrated an increased Stroop effect in a number of studies compared to young adults [14–17]. … Indeed, others have systematically demonstrated that it is possible to reduce the Stroop effect by averting the eyes from centrally presented stimuli or by blurring vision [24].
