PSY407H1 Lecture Notes - Lecture 1: Biopsychosocial Model, Substance Abuse, Dsm-5
Document Summary
Addiction involves: use despite harm, loss of control, and motivation priorities out of whack. Addiction: a primary, chronic disease of brain reward, motivation, memory, and related circuitry. Biological (disease/medical) models which stipulate that addiction involves pathological changes in the brain resulting in dependence. Psychological models which believe that since the act of taking drugs is followed by pleasurable consequences, the act is repeated. Social models believe that the environment leads to addiction. Biopsychosocial model incorporates all of the above. Dsm v includes tolerance, withdrawal, use more than intended, cutting down efforts fail, life revolves around he activities, compulsive use despite harm, and craving (new to this version). Dislocation theory depicts addiction as a means of adapting to a modern world that is full of fragmentation from others. Classical conditioning is an example (cues become linked to the drug, can trigger. Includes features such as expectancies, attitudes, and beliefs wanting). Operant conditioning involves the rewards (or drawbacks) influencing the behaviour.
