- Create one test run and verify the CSV columns before class.
- Choose whether students run all three tasks or work in groups.
Attention and inhibition lab
A 50-minute class using Stroop, Flanker, and Go / No-Go tasks to compare interference, speed, accuracy, and response inhibition.
Class flow
The complete plan uses 50 minutes.
- 8 min · Question: Predict which conditions will slow responses or increase errors.
- 15 min · Run tasks: Students complete assigned tasks with practice enabled.
- 10 min · Inspect rows: Export CSV and identify condition, correctness, and reaction-time fields.
- 12 min · Compare: Compute condition summaries after applying the stated exclusion rule.
- 5 min · Debrief: Discuss speed-accuracy trade-offs and browser timing limits.
Data and analysis
Core fields: condition, trial_type, response, correct, rt, session_id.
- How much slower were incongruent trials than congruent trials among correct responses?
- Did participants trade accuracy for speed in any task?
- How did the exclusion rule change the condition estimate?
