According to the James-Lang theory of emtion, emotional experiences arise from physiological arousal.

Explanation:

The James-Lang theory of emotion is the result of the combination of the theories proposed by William James and Carl Lang, and it is one of the oldest theories of emotion. It states that we feel emotions after feeling and interprenting a certain physiological arousal. While common sense can make us believe that we feel an emotion and then a particular physiological reaction appears, the James-Lang theory says the opposite. For example, while we might think that we feel fear due to an external stimuli and then our hands begin to sweat due to that fear, the James-Lang theory proposed that our hands begin to sweat due to an external stimuli and then we interpret our reaction as fear.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
