Description
Return a toy's side under an alternating counterbalance rule.
Developmental-study observations use explicit trial, age, stimulus and missing-data conventions. Counterbalance flags and observation shares describe supplied research records; they do not establish actual stimulus presentation, an age correction appropriate for clinical use or a developmental assessment.
Return a toy's side under an alternating counterbalance rule.
When to use this tool
Use Toy Side Counterbalance Parity when checking the stated child-study observation, timing or record convention.
How to use the tool and how it works
- Enter trialIndex, initialRight, reversed. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read rightSide. Inspect rightSide before interpreting the associated values.
Return a toy's side under an alternating counterbalance rule. Require nonnegative whole trialIndex; combine trial parity with initialRight, then flip the Boolean when reversed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| trialIndex | Zero-based whole trial position; parity changes the side. | Required. Safe integer; minimum 0. |
| initialRight | Initial Right | Required. Boolean. |
| reversed | Reversed | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| rightSide | Right Side | Required. Boolean. |

}Limitations and assumptions
- The index is zero-based; actual stimulus placement, appropriate counterbalancing and developmental interpretation 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
Review the study protocol, actual observations and consent/assent records; use validated assessment and qualified professional judgment for developmental or care decisions.
