Description
Return looking-time recovery relative to habituation drop.
Developmental research scores can be expressed as changes, ratios, reversed scales or contrasts between conditions. Those arithmetic forms have distinct denominators and need a suitable measurement model before they support psychological interpretation.
Return looking-time recovery relative to habituation drop.
When to use this tool
Use Infant Looking Recovery Baseline Term when checking a supplied score or response contrast.
How to use the tool and how it works
- Enter baselineLooking, habituatedLooking, recoveryLooking. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read habituationDrop, recoveredLooking, recoveryFraction. Use the output convention below.
Return looking-time recovery relative to habituation drop. Require baselineLooking > habituatedLooking >= 0 and recoveryLooking >= 0; divide recovery-habituated by baseline-habituated and return both differences.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| baselineLooking | Baseline Looking | Required. Finite number. |
| habituatedLooking | Habituated Looking | Required. Finite number; minimum 0. |
| recoveryLooking | Recovery Looking | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| habituationDrop | Habituation Drop | Required. Finite number. |
| recoveredLooking | Recovered Looking | Required. Finite number. |
| recoveryFraction | (recoveryLooking-habituatedLooking)/(baselineLooking-habituatedLooking); not a standardized assessment score. | Required. Finite number. |

}Limitations and assumptions
- The recovery fraction may be negative or above one; no habituation mechanism is established.
- 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 validated instruments, an appropriate study design and professional assessment when interpreting individual development or cognitive function.
