Reaction Time
2 tokens / session
Measure how fast participants respond to a stimulus with millisecond precision.
Choose this if
you run Stroop tasks, visual search, priming, go/no-go, or any task where speed matters.
Results look like
mean RT per condition, RT distributions and accuracy – »congruent trials: 487 ms, incongruent: 612 ms«.

Starter templates
Lexical decision – starter
Classic psycholinguistic task: is this letter string a real word? Measures word/nonword RT and accuracy. Replace these strings with your own; keep nonwords matched to words on length and syllable count so the contrast is not a length confound.
Semantic priming – starter
A prime word appears, then a target. Related primes speed the target up; the priming effect is unrelated − related mean RT. Each target appears once with a related prime and once with an unrelated one, so the contrast is within-target.
Stroop task – starter
Classic colour-word congruency RT task. Measures the Stroop effect (incongruent − congruent mean RT).
Simon task – starter
Spatial-compatibility RT task. Stimulus side vs response side; Simon effect = incompatible − compatible mean RT.
MTurk-ready Stroop – starter
Classic Stroop wired for MTurk. Server-side completion code mints on the thank-you page after attention checks pass. Set PayoutMode = PANEL_PER_SESSION in the Recruitment step and paste the redirect URL into your HIT.
Eriksen flanker – starter
Respond to the direction of the centre arrow while ignoring the flankers. Flanker effect = incongruent − congruent mean RT. Keep congruent and incongruent counts balanced so the contrast is not confounded with frequency.
Go / No-go – starter
Respond as fast as possible to Go stimuli and withhold the response on No-go stimuli. Measures prepotent-response inhibition: RT on Go trials plus commission errors on No-go trials. Keep No-go trials rare (roughly 25%) so the Go response stays prepotent.
IAT-lite – starter
Reduced Implicit Association Test. Concept and attribute words are sorted with the same two response keys; in the shared block the pairing is compatible, in the conflicting block it is reversed. The D-style score is the RT cost of the conflicting mapping. Replace these words with your own concepts and attributes, and counterbalance block order across participants.
