The chapter introduces key ideas from evolutionary psychology, including the concept of psychological mechanisms as functionally specialized adaptations. The chapter then examines three types of mechanisms that play a prominent role in the etiology of mental disorders, namely the motivational-emotional systems that drive goal-directed behavior, the processes involved in decision-making and self-regulation (e.g., executive functions), and the mechanisms that underlie mechanistic and mentalistic cognition. The chapter ends with a review of key neurobiological systems and their main behavioral functions. The systems considered here include brain monoamines and “social” neuropeptides such as oxytocin, excitatory and inhibitory neurotransmitters, sex hormones, and the stress response system.
