What largely explains why Caroline isn't receiving the reinforcement of bubblegum?

The concept of a "Restricted Range of Options" addresses the limitations Caroline faces in accessing the reinforcement of bubblegum. This implies that there may be a lack of available choices that meet her needs or the specific context in which she is trying to receive reinforcement. When options are limited, it can obstruct the likelihood of reinforcement occurring because the individual may not be able to engage with the desired behavior in a rewarding context.

For Caroline to receive reinforcement effectively, there should be a variety of opportunities to earn or access the reinforcement. A restricted range can prevent her from experiencing the positive outcomes associated with her behavior, leading to diminished motivation or engagement. This focuses on the environment and conditions around her rather than her personal reactions or emotional states, which might not fully account for the failure to receive bubblegum as reinforcement.
