Description
Compare observed stimulus-onset interval with a target.
Cognitive research records can encode stimuli, response timing, probability assumptions and observation support. Local differences and caller-defined tolerance labels do not establish perceptual validity, a cognitive mechanism, statistical equivalence or a clinical assessment.
Compare observed stimulus-onset interval with a target.
When to use this tool
Use Stimulus Onset Interval Residual when checking a supplied cognitive-task timing, stimulus, probability or evidence convention.
How to use the tool and how it works
- Enter firstOnset, secondOnset, suppliedTargetInterval. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read observedInterval, residual. Use the output convention below.
Compare observed stimulus-onset interval with a target. observedInterval = secondOnset-firstOnset, residual = interval-suppliedTargetInterval.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstOnset | First Onset | Required. Finite number. |
| secondOnset | Second Onset | Required. Finite number. |
| suppliedTargetInterval | Supplied Target Interval | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| observedInterval | Observed Interval | Required. Finite number. |
| residual | Signed difference in the direction stated above, with matching units. | Required. Finite number. |

}Limitations and assumptions
- Signed intervals and residuals are retained; clocks, actual display timing and appropriate experimental tolerance are not verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a validated study design, calibrated measurements and appropriate statistical/professional interpretation for cognitive or health conclusions.
