Question

14 fun and the brain scientists have performed some interesting recent experiments in the area of neuroscience to study how the brain reacts to \boring\ and \fun\ tasks and to try to determine the neural mechanisms of intrinsic motivation. in a 2015 study of 16 chinese graduate and undergraduate students, who were hooked up to electrodes and faced with two separate tasks, researchers found a significant difference in electrophysiological response depending on the task being offered. so clearly the brain is most motivated by fun - a biological reason to rely on intrinsic motivation to achieve and succeed as we work and learn. to ice cream after every swim lesson, that parent might assume that the child will eventually learn to love swimming. however, research has disproven this argument in favor of extrinsic motivation. in fact, incentivizing a childs behavior with rewards actually lessens their intrinsic motivation and makes the child less likely to pursue the activity on his or her own in the future. how does the author appeal to the reader in paragraph 14?

Explanation:

The author uses scientific research (a 2015 study) to support the argument about motivation. This is an appeal to scientific evidence.
