Collectively, their research established that certain behaviors could be learned or unlearned, and these theories have been applied in a variety of contexts, including abnormal psychology. [4] Theories specifically applied to depression emphasize the reactions individuals have to their environment and how they develop adaptive or maladaptive ...
Depression, which may be a similar kind of defense mechanism, may have become dysregulated as well. [31] Thus, unlike other evolutionary theories this one sees depression as a maladaptive extreme of something that is beneficial in smaller amounts. In particular, one theory focuses on the personality trait neuroticism. Low amounts of neuroticism ...
Figure 1: The adaptive and maladaptive cycles resulting from agonistic (hierarchical) encounters. [5]Unlike other evolutionary explanations of depression, rank theory is able to explain why depression is incapacitating: [1] by functioning as a substitute for physical damage, incapacitation prevents the 'loser' from posing a threat to the competitor they challenged.
The triad forms part of his cognitive theory of depression [4] and the concept is used as part of CBT, particularly in Beck's "Treatment of Negative Automatic Thoughts" (TNAT) approach. The triad involves "automatic, spontaneous and seemingly uncontrollable negative thoughts" about the self , the world or environment , and the future.
Herbert "Harry" Stack Sullivan (February 21, 1892 – January 14, 1949) was an American Neo-Freudian psychiatrist and psychoanalyst who held that "personality can never be isolated from the complex interpersonal relationships in which [a] person lives" and that "[t]he field of psychiatry is the field of interpersonal relations under any and all circumstances in which [such] relations exist".

Evolutionary psychiatry, also known as Darwinian Psychiatry, [1] [2] is a theoretical approach to psychiatry that aims to explain psychiatric disorders in evolutionary terms. [3] [4] As a branch of the field of evolutionary medicine, it is distinct from the medical practice of psychiatry in its emphasis on providing scientific explanations rather than treatments for mental disorder.
Critics of evolutionary psychology accuse it of promoting genetic determinism, pan-adaptationism (the idea that all behaviors and anatomical features are adaptations), unfalsifiable hypotheses, distal or ultimate explanations of behavior when proximate explanations are superior, and malevolent political or moral ideas.
The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. [ 1 ] Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 2 ]
