Reaction-time builder

Online reaction-time test builder for browser tasks

A useful online reaction-time task needs simple instructions, reliable response mapping, readable trial rows, and a smoke check before participants see it.

Task shape

Start with a clear instruction routine, a short practice routine, and a formal block with enough trials to compare conditions.

  • Instruction
  • Practice
  • Formal block
  • Completion

Export fields

Each trial should export fields that stay understandable outside the builder. Analysis gets easier when every row carries condition and phase labels.

  • rt
  • response_key
  • correct
  • condition
  • stimulus_id
  • phase

Pre-publication check

Before sharing, run the task end to end, confirm the button or key path, and verify that completion data reaches the collection endpoint.

  • Runtime smoke
  • Key mapping
  • Completion event
  • Data upload

FAQ

What should an online reaction-time test include?

Use short instructions, practice trials, formal blocks, visible response mapping, and trial-level fields for reaction time, response key, correctness, condition, and stimulus id.

Are browser reaction-time tests useful?

Browser tasks can support lightweight studies and product research. Lab-grade protocols still need device validation and stricter timing control.

What should be checked before sharing?

The audit should catch empty screens, missing keys, unreachable branches, weak data fields, and incomplete publication settings.
