How is whole interval recording implemented effectively?

Whole interval recording is a data collection method used in behavioral assessment where observers record whether a behavior occurs throughout the entire duration of a predetermined time interval. This method is designed to capture the presence of a behavior during the entire interval rather than at any time within it.

The reason that confirming occurrences only when fully observed is the correct implementation of whole interval recording is that the purpose of this method is to ensure that only those behaviors that persist for the whole duration of the interval are counted. This means that if the behavior only occurs for a part of the interval, it will not be recorded as an occurrence. This approach helps in understanding not just if a behavior happens but how consistently it happens over time, providing a clearer picture of the behavior's frequency and duration.

In contrast, methods that involve noting occurrences during split intervals or counting any response that occurs in the interval do not align with the principles of whole interval recording, as they would either capture partial occurrences or fail to require a full duration of behavior to be recorded. Ignoring partial occurrences is also essential to properly utilize this technique, as it ensures that only complete occurrences are reflected in the data collected.
