Arithmetic Verification

A true-or-false arithmetic task that probes mental calculation and processing efficiency.

No data is recorded

Participant experience on smartphone

A short equation is shown with correct / incorrect buttons.

When to use

Useful in studies of fatigue, attention, and momentary mental effort where a simple symbolic task is appropriate.

When not to use

Less suitable for participants with math anxiety or where arithmetic skill would confound the target construct.

How to use in a study

Keep the first implementation limited to one-step problems and two responses.

Researcher-configurable parameters

  • Difficulty level
  • Operation type
  • Timed versus untimed
  • Number of trials

Outputs collected

  • Accuracy
  • Reaction time
  • Performance by difficulty

Interpretation notes

Best treated as an optional research tool, not a default core task for all studies.

Scientific evidence

  • Brief symbolic verification tasks fit smartphone delivery well and can broaden working-memory coverage.
