ERIKSEN FLANKER TASK PDF

The subject must focus on a target stimulus while ignoring adjacent flanker stimuli. Besides the Stroop and Simon paradigm, the Eriksen Flanker paradigm is one of the three popular tasks to study effects of conflicting stimulus information. To measure how conflicting information affects choice response speed, different conditions are introduced: Congruent All stimuli map to the same response. Incongruent The flanker stimuli map to a different response than the target stimulus. Neutral The flanker stimuli have no associated response.

The subject must focus on a target stimulus while ignoring adjacent flanker stimuli. Besides the Stroop and Simon paradigm, the Eriksen Flanker paradigm is one of the three popular tasks to study effects of conflicting stimulus information.

To measure how conflicting information affects choice response speed, different conditions are introduced: Congruent All stimuli map to the same response. Incongruent The flanker stimuli map to a different response than the target stimulus. Neutral The flanker stimuli have no associated response. In addition, costs of shifting instructions may be studied by asking the subject to switch focus between central and flanker stimuli depending on a cue.

Conflict scores are computed by subtracting the faster condition from the slower condition for each of the attention concepts: Inhibition: InCongruent — Congruent response conflict Shifting: Mixed Focus — Single Focus task switching The executive subsystem in the Attentional Network Test corresponds to the Eriksen inhibition score.

Edit In the original test described by Eriksen and Eriksen in , [1] letter stimuli were used. Subjects were instructed to make a directional responses to certain letters, for example a right response to the letters H and K, and a left response to S and C. Each stimulus consisted of a set of seven letters, with the target in the central position. Other variants have used numbers, [2] or colour patches [3] as stimuli. These examples all use an arbitrary mapping between the stimulus and the response.

Eriksen flanker task

Procedure and method[ edit ] In an Eriksen Flanker Task there are three types of stimuli used: Incongruent, congruent, and neutral stimuli represented by arrows. This is what a participant may see in a standard Eriksen Flanker Task Congruent stimulus- Flankers call for the same response as the target, and may appear identical. Incongruent stimulus- Flanker items call for the opposite response of the target and are represented by different symbols. Neutral stimulus- Flanker items neither call for the same response nor evoke response conflict.
