Simon Effect Magnitude Calculator
Observed SimonincongruentminuscongruentRT; signed result retained, actual matching units and definitions independently established.
Description
The Simon effect can be summarized as incongruent minus congruent reaction time under matched task conditions.
The Simon effect can be summarized as incongruent minus congruent reaction time under matched task conditions.1
This tool calculates that signed difference without interpreting it as an individual cognitive diagnosis.
When to use Simon Effect Magnitude Calculator
This tool calculates that signed difference without interpreting it as an individual cognitive diagnosis.
How to use Simon Effect Magnitude Calculator and how it works
- Prepare qualified simon incongruent rt ms, qualified simon congruent rt ms, using the input definitions and matching units below.
- Enter the required fields and run Simon Effect Magnitude Calculator.
- Read result.value using the units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualQualifiedSimonIncongruentRtMs | Actual Qualified Simon Incongruent Rt Ms. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
| actualQualifiedSimonCongruentRtMs | Actual Qualified Simon Congruent Rt Ms. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
Require nonnegative qualified incongruent and congruent Simon-task times in ms. Return incongruent minus congruent as a signed ms result. Trial selection, response summary and protocol matching are external.
simonEffectMs=incongruentRtMs-congruentRtMs Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Milliseconds under the stated reaction-time mean or signed-difference convention. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
Alternative or Complementary methods
Use Task Switching Cost Calculator for a complementary operation: Task-switching cost describes the difference between qualified switch-trial and repeat-trial response times.
Use Inhibition of Return Magnitude Calculator for a complementary operation: Inhibition of return can be summarized as cued-return minus uncued reaction time under a matched protocol.
