Sheryl is demonstrating extrinsic motivation.
Step-by-step explanation:
Motivation can arise from intrinsic of extrinsic factors. Intrinsic factors are the ones that come from within, such as feeling good about oneself, enjoying helping others, etc. Extrinsic motivators are external factors, such as money, fame, praise, and grades.

The reward is external, not changing Sheryl's feelings and perceptions of herself.
