Females are more conservative & more selective. Females have demanded long term comments before consenting to sex. *Evolutionary Theories predicts that Men places more emphasis on youth & attractiveness.

There is a predisposition. *One study: Anterior Hypothalamus is half the size in gay men. *Prenatal Development: Hormonal secretion during critical periods can influence sexual orientation. (DES, reduces miscarriages) (adrenal disorders) –Interactionist 16Motivation & Emotion

28. Theories of Emotion James-Lange –Feel afraid because pulse is racing. Different patterns of autonomic activation lead to the experience of different emotions. Cannon-Bard (SAME TIME) cannon ball –Thalamus sends signals simultaneously to the cortex and the autonomic nervous system Schacter’s Two-Factor Theory (SITUATION) –Look to external cues to decide what to feel Evolutionary Theories –Innate reactions with little cognitive interpretation 28 Motivation & Emotion
