Hence: complex interaction b/w behavioural & biological factors -> increased phobia risk. Developmental critical period: more/less reactive to a situation. Jody; blood phobia; u. r. associated w/ similar situations of u. s. ; Various components of a multidimensional integrative approach to psychopathology. One dimensional: trace origins to single cause; systemic perspective on causality. Jody: 7 days gradual exposure to blood + applied muscle tension (lower bp) -> escape phobia. Genes: influence physical characteristics; can also influence behaviour, traits, personality. 23 pairs of chromosomes; provide programs for development of body/brain. Problems with ordering of base pairs of double helix -> defective gene; Hence quantitative genetics: sum up tiny effects across multiple genes.
