Document Summary

Psyco 275 - lecture #3 - evolution of human brain and behaviour/neurogenetics. Evolution of human brain and behaviour: the more complex your body movement is, the larger your brain becomes, jerison. Proper mass led to the idea that you could control how big a brain would become. Humans have largest eq (neanderthals were actually bigger) Why the hominid brain evolved: 3x larger, lifestyle. Friends are also there to help you. Requires good sensory, spatial and memory skills. Changes in facial features allowed and required changed in diet. Increased in cerebrovascular network facilitated cooling of brain: rate of development. Extended infancy/stages of maturation allow more brain cells. Socialization allows for extended parental caregiving: modern human brain size/intelligence. Hard to make brain behaviour comparison between members of the same species. Difficulty to make brain-behaviour comparisons between members of the same species. Problem of causality (third variable between the correlation of brain size and iq)
