Paradigm overview
The Simon Task measures conflict between stimulus identity and spatial response compatibility. ConductCognition reports the Simon effect, accuracy, and congruency-related accuracy cost.
Key scoring outputs
Simon Effect
msIncongruent correct RT minus congruent correct RT.
Lower is typically more efficient
Congruency Accuracy Cost
proportionCongruent accuracy minus incongruent accuracy.
Lower cost is typically better
Mean Correct RT
msMean response time on correct trials.

Research FAQ
Common questions about this online cognitive test
What does this test measure?
Simon Task is used for stimulus-response conflict, cognitive control, response selection research workflows.
What data can researchers export?
Researchers can export scored results, and paid plans support trial-level exports for deeper analysis.
Is this for clinical diagnosis?
ConductCognition is for research use. The platform supports task delivery, scoring, and exports; clinical interpretation remains outside the platform.
