Document Summary
Evolutionary theory: hold that natural selection favors behaviours that maximize reproductive, human motives and those of other species are the product of evolution, just an anatomical characteristics are, evolutionary analyses of motivation are based on premise that motives can be best understood in terms of adaptive problems they solves for our hunter gatherer ancestors. Human sexual response: sexual response cycle is 4 stages: excitement, plateau, orgasm, resolution, excitement, rises rapidly, muscle tension, respiration, heart rate increase, blood pressure increase, vasocongestion, engorgement of blood vessels, plateau, tightening of vaginal entrance, preejaculation, orgasm, reaches peak, muscle contractions, resolution, physiological changes subside, men experience refractory period, following orgasm when males are largely unresponsive to further stimulation, increases with age. Front portion of cingulate cortex implicated in the processing of pain: neural circuit (mesolimbic dopamine pathway) plays major role in experience of pleasurable emotions associated with rewarding events, mirror neurons, behavioural component.
