Question 1

Observer drift is defined as:

Accepted Answer

Gradual, unaware changes in an observer's application of measurement criteria over time

Answer

Observer drift occurs when an observer's behavioral definitions slowly shift from the originally trained standard without the observer realizing it.

Question 2

The most effective strategy to detect and correct observer drift is:

Accepted Answer

Scheduling periodic retraining sessions and IOA checks throughout the study

Answer

Regular IOA assessments and recalibration against the original operational definitions identify drift early and allow correction before data quality is compromised.

Question 3

Reactivity in behavioral measurement means that:

Accepted Answer

The behavior changes as a direct result of being observed or measured

Answer

Reactivity is a measurement artifact in which the observation process itself alters the rate or form of the behavior being measured.

Question 4

Permanent product recording measures:

Accepted Answer

Physical outcomes or artifacts that persist after the behavior ends

Answer

Permanent product recording assesses the lasting physical results of behavior (e.g., completed worksheets, items assembled) rather than the behavior itself.

Question 5

Which of the following is a key advantage of permanent product recording?

Accepted Answer

The observer does not need to be present when the behavior occurs

Answer

Because permanent products persist after the behavior ends, an observer can evaluate them at any convenient time without needing to witness the behavior directly.
