2026 COMPLETE QUESTIONS AND CORRECT
ANSWERS GRADED A+
◉ modeling.
Answer: a behavior change strategy in which learners acquire new
skills by imitating demonstrations of the skills by live or symbolic
models. the model shows, demonstrates, or conveys exactly the
behavior the learner is expected to convey. can be live, symbolic, or
recorded
◉ shaping.
Answer: the differential reinforcement of successive approximations
toward a terminal behavior. the antecedent stimulus for the terminal
behavior stays the same, while the response progressively becomes
more differentiated
◉ differential reinforcement.
Answer: presenting an unconditioned or conditioned reinforcer only
to those emitted members of a response class that share a specified
dimension or quality, while placing all other emitted response class
members on extinction
◉ performance dimensions that can be shaped.
, Answer: 1. topography: refining motor movements
2. rate: increasing number of correct responses
3. latency: decreasing compliance time between a directive
4. duration: increasing time spent on task
5. IRT: reducing rapid eating
6. magnitude: increasing projected voice volume
◉ shaping guidelines.
Answer: 1. select the terminal behavior and define it precisely
2. determine the criterion for success
3. assess the response repertoire
4. identify behaviors to reinforce
5. eliminate interfering or extraneous stimuli
6. proceed gradually
7. limit the number of approximation at each level
8. continue to reinforce when terminal behavior is achieved
◉ behavior chain.
Answer: a linked sequence of responses leading to a terminal
outcome. each response produces a stimulus change that functions
as conditioned reinforcement for that response and as a
discriminative stimulus for the next response in the chain.
reinforcement for the last response in a chain maintains the
