Final answer:
Susan is intrinsically motivated, as she plays the violin for her personal enjoyment and satisfaction. Her motivation is characterized by the internal fulfillment she derives from mastering the instrument rather than extrinsic factors.
Step-by-step explanation:
Susan's statement that, "Hearing myself play the violin makes me practice even more in order to master this instrument," suggests that her primary motivation is B) Intrinsic motivation. Intrinsic motivation is where the behavior itself is its own reward, and the individual engages in the activity for the sake of personal satisfaction or fulfillment. This contrasts with extrinsic motivation, where the behavior is driven by external rewards, such as money or praise.
In Susan's case, her enjoyment of the music she creates while playing the violin motivates her to practice and improve. It is the internal pleasure and the challenge of mastering the violin that fuels her desire to continue, not external factors such as compensation or accolades. Therefore, her motivation does not fall under extrinsic motivation, fear of failure, or competition.
Research has indicated that intrinsic motivation can be sustained or even increased with verbal praise, which can be considered an extrinsic factor. However, this reinforcement does not necessarily diminish the intrinsic enjoyment of the activity, as seen in the case provided where Odessa bakes more eagerly if she receives compliments.
