Flanker Task

The target is flanked by non-target stimuli which correspond either to the same directional response as the target (congruent flankers), to the opposite response (incongruent flankers), or to neither (neutral flankers). The test can be used to assess the ability to suppress responses that are inappropriate in a particular context.

Randomisation is according to these rules:

1. No more than 3 consecutive sides (direction).
2. No more than 2 consecutive flanker (congruency).
3. Never two consecutive trials that have the same congruency AND side.
