Document Summary

Distal antecedents (literal translation: far precursors: neurobiological factors (genetic predisposition, psychosocial factors (impulsivity, poverty, exposure to the object. Interaction with the object: desirable subjective shift. *addiction has not yet developed at this time: 2. Proximal antecedents (literal translation: near precursors: biopsychosocial factors (trauma, hormones, repeated interaction, repeated desirable subjective shifts. *premorbid addiction syndrome develops at this time: 3. Consequences/outcomes: some outcomes unique to the object (gambling=debt, smoking=lung cancer, some outcomes common across all objects (tolerance, relapse, treatment, criminal behavior) *full addiction syndrome with consequences at this point. Genetics: genes: segments of dna (deoxyribonucleic acid, certain traits, such as intelligence and personality are polygenic. Behavioral genetics: how can we determine whether a trait is genetic, look at sibling and twin studies. Looking for the concordance rate among the different types of twins. Concordance rates: the chance that 2 individuals have the same trait, copy chart from powerpoint.
