Final answer:
The assertion that extrinsic rewards can cause a decline in intrinsic interest is true, known as the overjustification effect, although the impact can vary based on the type of reward and expectations.
Step-by-step explanation:
The question at hand pertains to the interplay between intrinsic motivation and extrinsic rewards. The answer is true; when extrinsic rewards are given for performing an inherently interesting task, research suggests it can lead to a decline in intrinsic interest. This phenomenon is referred to as the overjustification effect and has been supported by multiple studies, such as those by Deci and colleagues.
This effect holds particularly true when the rewards are tangible and expected, as opposed to being intangible (such as praise) or unexpected. However, it's important to note that this is not a universal rule, as some studies suggest that extrinsic reinforcements like praise might actually bolster intrinsic motivation, depending on the context and the nature of the task and reward.
Using Odessa's baking passion as an example, adapting her hobby into a paid job might lead to a reduction in her desire to bake during her personal time. This change in motivation represents the potential impact of extrinsic rewards on intrinsic motivation.
