ERIKSEN FLANKER TASK PDF

The Eriksen Flanker Paradigm measures the effect of conflicting information within a stimulus set. 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:.

The Eriksen Flanker Paradigm measures the effect of conflicting information within a stimulus set. 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:. 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:.

The executive subsystem in the Attentional Network Test corresponds to the Eriksen inhibition score. This implementation uses arrows or fishes as stimulus material. The three attentional networks: on their independence and interactions.

Sequential dependencies in the Eriksen flanker task: A direct comparison of two competing accounts

The data are available under: DOI In the Eriksen flanker task as well as in the Simon task irrelevant activation produces a response conflict that has to be resolved by mental control mechanisms. Despite these similarities, however, the tasks differ with respect to their delta functions, which express how the congruency effects develop with response time. The slope of the delta function is mostly positive for the flanker task, but negative for the Simon task.

Eriksen flanker task

The term Eriksen Flanker Task refers to a set of response inhibition tests used in cognitive psychology to assess the ability to suppress responses that are inappropriate in a particular context. In the tests, a directional response generally left or right is made to a central target stimulus. The target is flanked by non-target stimuli which correspond either to the same directional response as the target congruent flankers or to the opposite response incongruent flankers. It is found that response times are slower for incongruent stimuli than for congruent stimuli.
