Explanation:
Nancy decided to take introductory psychology because she has always been interested in human behavior. Jack enrolled in the same course because he thought it would be easy. Nancy's behavior was motivated by <u>intrinsic motivation</u>, while Jack's was motivated by <u>extrinsic motivation</u>.
Intrinsic motivation is a type of behavior or motivation that is driven by internal rewards such as the satisfaction of fulfilling a purpose/living for a purpose or self satisfying desires, while extrinsic behavior is a behavior motivated by external rewards such as promotion at work, good grades as in the case of Jack.
Chronic, low-grade depressed feelings are to "dysthymic" disorder as moderate, recurring mood swings are to "<span>cyclothymic"</span> disorder.
Dysthymic disorder is a genuine condition of interminable discouragement, which holds on for no less than two years (one year for youngsters and youths). Dysthymia is less intense and serious than significant depressive issue.
In cyclothymic disorder, temperaments swing between brief times of mellow wretchedness and hypomania, a raised disposition. The low and high emotional episodes never achieve the seriousness or length of significant depressive or full insanity scenes.
