- Applied Behavior Analysis Core ABA Principles Questions and Answers Flashcards

In a multiple baseline design across behaviors, a researcher introduces the intervention to one behavior at a time. The primary purpose of this staggered introduction is to:

Answer: Demonstrate experimental control by ruling out confounds

Staggering intervention introduction across baselines demonstrates that behavior change coincides with intervention onset, ruling out extraneous variables.

The Premack Principle states that:

Answer: Higher-probability behaviors can serve as reinforcers for lower-probability behaviors

The Premack Principle holds that access to a high-frequency preferred activity can reinforce a low-frequency less-preferred activity.

Which measurement dimension captures how much time elapses between the onset of a stimulus and the initiation of a response?

Answer: Latency

Latency measures the time between the presentation of a stimulus (or instruction) and the onset of the target response.

A behavior that was previously reinforced is placed on extinction. Shortly after extinction begins, the behavior temporarily increases in rate or intensity. This phenomenon is called:

Answer: Extinction burst

An extinction burst is the temporary increase in behavior rate or intensity that often occurs at the onset of an extinction procedure.

Which of the following best describes 'stimulus generalization' in ABA?

Answer: A learned behavior occurs in the presence of stimuli other than the original training stimulus

Stimulus generalization occurs when a conditioned response is elicited by stimuli similar to but not identical to the original discriminative stimulus.

An RBT observes that a client engages in self-injurious behavior immediately before transitions between activities. In an ABC recording, the transition would be recorded as the:

Answer: Antecedent

In ABC data collection, the antecedent is the event that occurs immediately before the behavior and may trigger it.

Which ethical principle requires behavior analysts to use the least restrictive, most effective intervention available?

Answer: Least restrictive alternative

The least restrictive alternative principle mandates selecting interventions that achieve goals with minimal intrusion on the individual's rights and freedom.
