A psychologist is helping a student improve his social skills. After instructing him on how to carry on a conversation with other students, the psychologist has the student practice. Practicing the behavior after receiving instructions is referred to as:

Rehearsal

Explanation:

The student is following a predetermined behavior in order to be successful on the process to interact with other people. Everything that is made by him is pre-composed on his mind because of the previous rehearsal introduced by the psychologist, and depending on the way how the student will interact with the others, he will be happy to achieve it or will be frustrated, and he will behave accordingly.

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.

i believe the answer is:   psychological  experiment

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.
