BCABA Stimulus Control and Antecedent Interventions 3

Question 1

In forward chaining, the learner:

Accepted Answer

Is taught the first step of the chain independently while the trainer completes all remaining steps

Answer

Is taught the last step of the chain first, working backward through each preceding step

Answer

Attempts the entire chain on every trial with prompting on steps not yet mastered

Answer

Must complete the entire chain independently before any reinforcement is delivered

Question 2

Backward chaining differs from forward chaining primarily because:

Accepted Answer

The learner is taught the last step of the chain first, with the trainer completing preceding steps

Answer

The learner is taught the first step first and reinforcement is delivered at the start of the chain

Answer

All steps are taught simultaneously with maximal prompting on every trial

Answer

Only the discriminative stimulus present at the final step serves as a conditioned reinforcer

Question 3

Total task presentation (TTP) is distinguished from forward and backward chaining in that:

Accepted Answer

The learner attempts every step of the entire task chain during each training session, with prompts provided as needed

Answer

The learner is taught only one step of the chain per training session

Answer

Mastery of each step must be demonstrated before the next step is introduced

Answer

The chain is broken into individual components that are taught separately and then linked

Question 4

Shaping involves delivering reinforcement for:

Accepted Answer

Successive approximations of a target behavior that progressively resemble the terminal goal

Answer

Only the fully formed terminal target behavior from the very first training trial

Answer

Any behavior that occurs in close temporal proximity to the discriminative stimulus

Answer

The most frequently occurring behavior in the learner's existing repertoire

Question 5

Multiple exemplar training (MET) is used primarily to:

Accepted Answer

Promote stimulus and response generalization across untrained stimuli, responses, and settings

Answer

Establish tight stimulus discrimination between highly similar stimuli

Answer

Reduce the number of prompts required during the initial stages of acquisition

Answer

Establish a conditioned reinforcer by pairing multiple neutral stimuli with an unconditioned reinforcer

Question 6

Stimulus equivalence refers to:

Accepted Answer

The emergence of untrained stimulus-stimulus relations following conditional discrimination training

Answer

Two or more stimuli that reliably evoke the same observable motor response

Answer

Stimuli that share an identical reinforcement history and therefore exert identical stimulus control

Answer

A group of stimuli that are physically identical in all measurable dimensions

Question 7

Which antecedent strategy reduces problem behavior maintained by access to a specific reinforcer by pre-session delivery of that reinforcer?

Accepted Answer

Manipulation of an abolishing operation (AO) to decrease the value of the reinforcer

Answer

Noncontingent reinforcement scheduled on a variable-time schedule

Answer

Antecedent exercise to reduce arousal levels before the session

Answer

Differential reinforcement of other behavior (DRO) implemented before the session begins
