ERIKSEN FLANKER TASK PDF

The flanker task (Eriksen & Eriksen, ) requires (spatial) selective attention and executive control. In this task, irrelevant stimuli have to be inhibited in order to. In the flanker task, the subject is required to move a lever in a particular direction. Which direction is required in condition B? a) Left b) Right. Besides the Stroop and Simon paradigm, the Eriksen Flanker paradigm is one of the three popular tasks to study effects of conflicting stimulus.

The flankers could be arrows pointing in the same direction as the target congruent the opposite direction incongruent or squares neutral. InCongruent — Congruent response conflict Shifting: Choice reaction times CRTs or RTs were then recorded and compared between congruent and incongruent conditions. Each stimulus consisted of a set of seven letters, with the target stimulus placed in the central position. Views Read Edit View history. The flanker taskalso known as the Eriksen flanker task, was designed in the early s by Eriksen and Eriksen.

The arrow version of the flanker test has also been evaluated as a method of detecting impairment due to alcohol and drugs in drivers at the roadside, [14] demonstrating the importance of selective attention skills to spatial abilities such as vehicle operation. A Group-Randomized Controlled Trial. Also, although most Eriksen Flanker Tasks show the flankers on the left and right of the target, they can also be placed taask or below the target, or in other spatial orientations.

The subject must focus on a target stimulus while ignoring adjacent flanker stimuli. Mixed Focus — Single Focus task switching. Just as with the Eriksen Flanker Task, the response time and accuracy of congruent words is better than those of incongruent words.

The participant is instructed to press the right or left button based on the content of the stimulus rather than its location. Eevaluation of a small group intervention in prekindergarten and kindergarten children. A variety of factors have flsnker shown to affect subject’s performance on flanker tasks.

Introduction The flanker taskalso known as the Eriksen flanker task, was designed in the early s by Eriksen and Eriksen.

Eriksen flanker task

Various psychiatric and neurological conditions also affect performance on flanker tasks. The study found that CRT was significantly greater in incompatible than compatible conditions, a difference termed the flanker effect.

There is a similarity between other paradigms in which this type of interference from an irrelevant stimulus or stimulus feature occurs like the Stroop task or the Simon task. Acute administration of antihistamine or alcohol taskk impairs CRT in test measures, a deficit which Ramaekers et al.

In cognitive psychologythe 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.

Click here to run a demo of the flanker task. Subjects were instructed to make directional responses to certain letters, for example a right response could be associated to the letters H and Kand a left response to Driksen and C.

Pages with DOIs inactive since Besides erilsen Stroop and Simon paradigm, the Eriksen Flanker paradigm is one of the three popular tasks to study effects of conflicting stimulus information.

These examples all use an arbitrary mapping between the stimulus and the response.

More recent work in this area has used neurophysiological measures such as eeiksen potentials [11] or imaging techniques such as fMRI. The executive subsystem in the Attentional Network Test corresponds to the Eriksen inhibition score. The save line of the PsyToolkit experiment script determines what is being saved in the data output file.

In the original test described by Eriksen and Eriksen inletter stimuli were used. To measure how conflicting information affects flankrr response speed, different conditions are introduced: A version of the Eriksen Flanker Twsk involving arrows as stimuli can be found and taken here. The word can either be congruent, which would mean the word would match the font color, such as the word “blue” in blue font color, or it can be incongruent where the word would not match the font color like the word “purple” in yellow font color.
