Online Flanker task design for attention and interference studies
An online Flanker task needs clean stimulus mapping, balanced congruency, clear response keys, and trial rows that separate speed from accuracy.
Stimulus table
The stimulus table should separate the target, flanker pattern, correct key, congruency, and condition label.
- target
- flankers
- correct_key
- congruency
- condition
Browser checks
Check that keyboard focus works, mobile fallback is clear, and every completion event reaches the data endpoint.
FAQ
What is a Flanker task?
A Flanker task asks participants to respond to a target while nearby distractors can support or conflict with the correct response.
Which fields should be exported?
Common fields include target direction, flankers, congruency, response key, correctness, reaction time, block, and trial id.
Can it run online?
Short demos, teaching tasks, and lightweight online studies fit browser delivery when timing limits are stated clearly.
