Document Summary
Unit 1: intro to psych: themes: development, evolution and neuroscience, foundational topics, 1. Development: gene-environment interactions across an individual"s lifespan: 2. Evolution: gene-environment interactions across the evolutionary history of a species: 3. Neuroscience: the study of the nervous system and the neural basis of thought and behaviour. Unit 3: studying development: changes earlier in life are more dramatic than later years, four ways to measure abilities in infants, 1. Polygenic inheritance: when multiple genes are involved in the expression of a trait: 3. Co-dominance: two dominant alleles are both fully and equally expressed to produce a phenotype that is a compromise b/t 2 genes ex. Abo blood type (both a and b are dominant alleles so the blood type expressed is ab: 4. Sex-linked inheritance: involves genes expressed on the x chromosome: responsible for disorders such as colour blindness, more common in females b/c have 2 x chromosomes.
