PSYB32H3 Lecture Notes - Psychoanalysis, Genetic Linkage, Unconditional Positive Regard
Document Summary
Genotype vs phenotype: genotype is what you are born with, inherited, unobservable, phenotype is the individuals observable behaviourable characteristics. It is a product of the genotype and the environment: family method. If a disorder is inherited, a family study should reveal a disease within the family. Probank case is the immediate relative with 10% higher chance of getting it: twin method. Twins are similar diagnostically speaking they are. If monozygotic twins show higher concordance rate than dizygotic twins, that shows inheritance plays a role: adoptees method. Twin sets born, but raised by non-biological parents. Environmental factors can be ruled out: linkage analysis. Researchers try to understand genetic role in disorders. Look for large collections of individuals in a large family unit that have a disorder. Look for similar markers between people with disorder. Belief that mental disorder caused by neuro-biological factors. Neurotransmission: check out video on slide. Reuptake: check out video on slide. Structure and function of the human brain.
