Final answer:
SDT theory suggests that emphasizing intrinsic rewards is the primary way to motivate high performance for uninteresting jobs.
Step-by-step explanation:
According to SDT theory, the primary way to motivate high performance for uninteresting jobs is to emphasize intrinsic rewards. Intrinsic rewards are rewards that come from within the individual and are inherently satisfying, such as a sense of accomplishment or enjoyment. Emphasizing intrinsic rewards can help individuals find meaning and satisfaction in their work, even if the job itself is not inherently interesting.
