Description
Return observed attachment-research episode time after exclusions.
Developmental task timing and coded sequences need a common clock and explicit rules for exclusions, adjacency and response windows. A delay, duration share or transition rate is descriptive rather than a measure of developmental status.
Return observed attachment-research episode time after exclusions.
When to use this tool
Use Attachment Research Episode Duration Term when checking a supplied task-time or coded-sequence convention.
How to use the tool and how it works
- Enter episodeStart, episodeEnd, excludedSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read wallSeconds, observedSeconds, excludedFraction. Use the output convention below.
Return observed attachment-research episode time after exclusions. Require episodeEnd > episodeStart and excludedSeconds in [0,elapsed]; return wallSeconds, observedSeconds and excludedFraction.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| episodeStart | Episode Start | Required. Finite number. |
| episodeEnd | Episode End | Required. Finite number. |
| excludedSeconds | Excluded Seconds | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| wallSeconds | Wall Seconds | Required. Finite number. |
| observedSeconds | Observed Seconds | Required. Finite number. |
| excludedFraction | Excluded Fraction | Required. Finite number. |

}Limitations and assumptions
- This does not classify attachment, evaluate the protocol or establish child welfare.
- 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 original observations and study design; use appropriate statistical and professional methods for developmental conclusions.
