Document Summary

Psychology 2075 chapter 2: theoretical perspectives on sexuality. Sociobiology: some behaviours are a result of evolution. In terms of evolution, what counts is producing lots of healthy, viable offspring who will carry on our genes. Evolution occurs via natural selection (the process by which the individuals who are best adapted to their environment are more likely to survive, reproduce, and pass on their genes to the next generation) How do humans choose mates: physical attractiveness of the person. Physique and complexion indicate the health and vigour of the individual; thus related to the person"s reproductive potential. In men, physiological sexual arousal is specific to stimuli depicting their preferred sexual partner; women show physiological arousal to stimuli depicting both their preferred and non-preferred sex partners, and even to stimuli of animals. Sexual selection: selection that results from differences in traits affecting access to mates.
