Final answer:
Jada is demonstrating intrinsic motivation by volunteering at a preschool because she enjoys it and wants to gain experience, while Carl is showing extrinsic motivation as he mows the yard for payment.
Step-by-step explanation:
The type of motivation Jada is showing is intrinsic motivation. Intrinsic motivation refers to doing an activity for its inherent satisfaction rather than for some separable consequence. In Jada's case, she volunteers at a local preschool because she enjoys working with children and gains personal satisfaction and experience from it. Her motivation is not driven by external rewards like money or praise, but by her personal enjoyment and desire to become a preschool teacher.
Similarly, the answer to the question about Carl mowing the yard is extrinsic motivation. Extrinsic motivation involves completing a task or engaging in an activity because of external rewards or pressures. For Carl, the external reward is the $20 he gets paid for mowing his elderly neighbor's yard. This reward is a tangible form of extrinsic reinforcement, which drives his motivation to perform the task.
