Final answer:
The statement regarding providing a sensory toy aligns with the 'instructions' component of Behavioral Skills Training (BST), offering initial guidance for desired behavior.
Step-by-step explanation:
The statement "First, provide her with a sensory toy" would most closely match instructions in the context of Behavioral Skills Training (BST). Instructions are the part of BST where the trainer provides detailed information on what the behavior looks like and how to perform it. In this case, the provision of a sensory toy is the initial guidance or instruction given to facilitate a desired behavior.
Modeling involves demonstrating the behavior for the learner to observe. Rehearse is when the learner practices the behavior, and feedback is provided after the rehearsal to help the learner improve their performance.
In the context of learning theory, associating sensory stimuli with learned behavior is a form of classical conditioning where a neutral stimulus (the sensory toy) becomes associated with a certain response. This association is created by repeatedly presenting the sensory toy together with the desired behavior.
