PSYC 2 Lecture Notes - Lecture 1: Hominidae, Human Brain, Evolutionary Developmental Biology
Document Summary
Biological psychology: explains behavior from a biological perspective. Aristotle: heart is for thought and emotion; brain was the cooling organ for heart. Hippocrates and plato: brain is the seat of thought and emotions. Galen: gave the modern view; connected gladiator head injury to see that brain mediated mental function, studied animal brains through dissections. Dualism: body and mind (aka the soul) are separate, distinct. Monism: not distinct entities; modern view of today. Brain machine interface seen with tetraplegia patient: brain disconnected from body. Lecture 1: origins of behavioral neuroscience, evolution, genetics, experience: bases of evolutionary theory. Diversity in the kinds of traits in a population (ex: phenotypes) Mutations, accidental changes in genetic information, provides variation. White moths turned black, actually became advantageous. Changing color (melanism) had better survival chances. Mendel: dominant and recessive alleles, crossing pea plants. Genotype vs phenotype with punnett square: differential reproductive success.
