Flanker

A brief inhibitory-control task that requires responding to a target while ignoring neighboring distractors.

No data is recorded

Participant experience on smartphone

A row of arrows or similar stimuli with two large response buttons.

When to use

Useful when a study needs a fast language-light measure of interference control.

When not to use

Not ideal if the study needs broad executive assessment from a single task.

How to use in a study

Use congruent and incongruent trials and keep the rule visible and simple.

Researcher-configurable parameters

  • Number of trials
  • Congruent / incongruent proportion
  • Stimulus duration
  • Practice enabled / disabled

Outputs collected

  • Congruent accuracy
  • Incongruent accuracy
  • Median reaction times
  • Interference score

Interpretation notes

Best interpreted as a repeated marker of executive interference control rather than a diagnostic instrument.

Scientific evidence

  • Flanker-style paradigms can be measured reliably on smartphones under suitable designs.
  • The visual, low-language format is a strong fit for mobile repeated testing.
