A behavior analyst needs to measure the force with which a client hits objects. Which dimension of behavior is being measured?
Answer: Intensity (magnitude)
Intensity (magnitude) describes the force or strength with which a behavior occurs and is distinct from how often or how long it occurs.
Which of the following best describes 'inter-response time' (IRT)?
Answer: Time from one response to the start of the next response
IRT is the elapsed time between the end of one response and the beginning of the next, reflecting response pacing.
A BCBA conducting a functional analysis runs conditions in a random order to control for:
Answer: Sequence effects and order bias
Randomizing condition order in a functional analysis controls for sequence effects that could confound which condition is responsible for behavior change.
What is the primary purpose of a 'brief functional analysis' compared to a full functional analysis?
Answer: It tests fewer conditions to quickly identify the maintaining function
A brief functional analysis tests a limited set of conditions (often one exposure per condition) to rapidly identify the maintaining function before a full analysis.
A BCBA observes that during free play a client self-stimulates at high rates but the behavior drops when engaged with a preferred toy. This pattern suggests the behavior may be maintained by:
Answer: Automatic (sensory) reinforcement
High self-stimulation during unstructured time that decreases when alternative stimulation is available suggests the behavior provides automatic sensory reinforcement.
Momentary time sampling is best suited for measuring behaviors that are:
Answer: Continuous and occur at very high rates
Momentary time sampling is efficient for high-rate or continuous behaviors because it only requires observation at the moment the interval ends.
When evaluating a completed ABC narrative recording, a BCBA groups similar antecedent-behavior-consequence sequences to identify:
Answer: Possible behavioral functions
Grouping ABC sequences reveals patterns that suggest which environmental events consistently precede and follow the behavior, pointing to its function.
