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

In forward chaining, the learner is taught to complete only the first step independently while the trainer completes the rest; additional steps are added sequentially until the learner performs the entire chain.

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

In backward chaining, the trainer completes all steps except the last, which the learner masters first; the procedure then works backward, adding one preceding step at a time until the learner performs the entire chain.

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

In TTP, the learner works through all steps of the task chain in every session with prompting provided for steps not yet mastered, making it efficient for learners who can acquire the full chain with minimal assistance.

Question 4

Shaping involves delivering reinforcement for:

Accepted Answer

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

Answer

Shaping involves reinforcing responses that progressively approximate the terminal behavior, raising the criterion for reinforcement as the learner's behavior comes closer to the final goal.

Question 5

Multiple exemplar training (MET) is used primarily to:

Accepted Answer

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

Answer

MET teaches a skill across diverse examples and contexts so that responding does not come under overly narrow stimulus control, thereby promoting generalization to untrained stimuli and settings.
