CBC Applied Behavior Analysis Foundations & Principles 3

Question 1

A 'motivating operation' (MO) in ABA is defined as an environmental variable that:

Accepted Answer

Alters the reinforcing or punishing effectiveness of a stimulus and the frequency of behaviors related to that stimulus

Answer

Triggers a conditioned response through stimulus-response pairing

Answer

Specifies which behavior will be reinforced in a given context

Answer

Reduces the effectiveness of extinction procedures

Question 2

Which of the following best describes the concept of 'shaping' in ABA?

Accepted Answer

Reinforcing successive approximations of a target behavior until the full behavior is achieved

Answer

Teaching a new behavior by breaking it into steps and prompting each step in sequence

Answer

Removing prompts gradually until the learner performs the behavior independently

Answer

Pairing a neutral stimulus with an unconditioned stimulus to elicit a response

Question 3

The concept of 'chaining' is used to teach behaviors that consist of:

Accepted Answer

A sequence of individual stimulus-response components linked together

Answer

A single complex movement that must be mastered as a whole unit

Answer

Multiple incompatible behaviors that must be alternated

Answer

Generalized responses across a variety of different settings

Question 4

In behavior analysis, 'stimulus control' is said to exist when:

Accepted Answer

The probability of a behavior is higher in the presence of a specific stimulus than in its absence

Answer

A behavior occurs at a high rate regardless of the antecedent conditions

Answer

A learner responds to all stimuli in the same way due to generalization

Answer

A punisher reliably suppresses the target behavior across all settings

Question 5

Which of the following best defines 'response generalization'?

Accepted Answer

Performing different but functionally similar responses to achieve the same outcome

Answer

A trained behavior occurring in new, untrained settings or with untrained people

Answer

Maintaining a skill over time without additional training or prompting

Answer

Transferring a skill learned in one sensory modality to another

Question 6

The principle of 'parsimony' in behavior analysis suggests that a behavior analyst should:

Accepted Answer

Favor the simplest, most straightforward explanation or intervention before considering more complex ones

Answer

Always use the most complex intervention to ensure comprehensive behavior change

Answer

Collect data on as many behaviors as possible to ensure thorough assessment

Answer

Implement multiple interventions simultaneously for maximum effectiveness

Question 7

Which of the following best illustrates 'behavioral momentum'?

Accepted Answer

Presenting easy, high-probability requests before a difficult, low-probability request to increase compliance

Answer

Delivering high rates of reinforcement at the start of a session to increase compliance with later requests

Answer

Reducing demands during an extinction burst to prevent escalation

Answer

Using punishment to quickly suppress a high-rate behavior
