Document Summary

Lecture #3: biopsychosocial approaches & developmental theories y-03-02: biopsychosocial approaches & developmental theories. The biological part is largely explained through genetics. Then we"ll work in the psychology and the social parts: biopsychosocial perspectives. Genes restrict development to a small range of outcomes. Not as rigid as canalization e. g. , trisomy 21: biopsychosocial perspectives. Genes set boundaries for range of phenotypes based on environment. Not as rigid as canalization e. g. , trisomy 21 y-03-02: pictorial example of range of reaction. Would mozart be a great musician if he had never been exposed to an instrument: biopsychosocial perspectives. Species-typical environments & experiences also influence developmental course. Bobwhite quails & maternal call (timing & absence) Epigenesis: bi-directional relationship btw all levels of biological & experiential variables (answer to nature vs. nurture) Genetic activity both influences and is influenced by structural maturation. Structural maturation is bi-directionally linked to function & activity. Structure: some substrate of the organism (i. e. nervous tissue, muscle, limbs, mental knowledge)
