Tarea Flanker

The flanker task measures your ability to focus on a target while ignoring irrelevant surrounding stimuli.

Congruent trials (all arrows point the same way) are easy. Incongruent trials (flankers disagree with the target) create response conflict.

The difference in reaction time between the two — the flanker effect — is a direct read-out of how efficiently your attentional filter works.

Training can shrink the flanker effect over weeks.

Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.

Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.

1. Arrows appear in a row. Ignore the outer arrows.
2. Tap or press the arrow key matching the middle arrow.
3. Respond fast, but only when you are sure.
4. Aim for minimal flanker effect.
