Final answer:
Tiana's shift from making dream catchers for fun to doing it for money is an example of the overjustification effect, where extrinsic rewards can dampen intrinsic motivation for a previously enjoyable activity.
Step-by-step explanation:
The phenomenon Tiana experiences when she no longer crafts dream catchers purely for fun but rather to generate income is known as the overjustification effect. This effect arises when an external incentive such as money diminishes one's intrinsic motivation to perform a task, which was previously driven by enjoyment or passion. What was once a leisurely activity becomes reclassified as work, and the intrinsic pleasure one receives from it may decrease. This change in motivation reflects a complex interplay between intrinsic and extrinsic motivations and highlights the potential downside of monetizing one's hobbies.
An example given in the supporting material tells the story of Odessa, who enjoys baking in her free time. When she begins baking as part of her job, her desire to bake outside of work lessens because the activity has transformed into an obligation rather than a freely chosen pastime. This illustrates how the introduction of external rewards can override intrinsic interest in an activity, leading to a decline in the initial motivation.
Understanding this effect is important in assessing how extrinsic rewards can influence personal choice and the dynamics of motivation. It can provide insights into how individuals make economic choices based on the balance between income and personal enjoyment.
