Document Summary
Nature and nurture: everything about you is jointly caused by the genetic material you inherited and the environments you have experienced from conception to now, how much does each one matter, depe(cid:374)ds o(cid:374) the philosopher"s views. John watson: nature has no role at all. Folk wisdom: environment matters: diet, type of training, neglect, etc. Behavioral genetics: explains how and why people behave differently from one another. Key terms: genotype: genetic material you inherit, environment: every aspect of your surroundings, including prenatal environment, phenotype: what you look like/are like, the expression of your genotype in your environment. Interactions of genes and the environment: classic experiment: took 7 different plant clippings, 3 of each clipping (which are identical) and compared them in different environments. At different elevations, different plants grew well based on the environment: many phenotypes can result from each genotype depending on the environment, human example: warrior gene, or maoa gene was believed to inhibit brain mechanism associated with aggression.
