Justin is 12 months old, and his uncle Frank is visiting for the first time in 6 months. Frank is delighted to see his nephew, so as he enters the room, he booms, "There's my little man!" Justin looks to his mother, who is smiling broadly at her brother Frank, and crawls to her to be picked up. Justin is demonstrating .

Social referencing

Explanation:

Social referencing is the behavioral attitude which infants use to respond or behave behaviors towards any thing, human, and situations. Social referencing is the  mechanisms by which a child tries understand the environment around them.

Social referencing happens when any child observes  the  facial expressions of other known person to understand how to behave in any  unknown situation.

When Justin was not able to recognize Frank, he needed hints how to respond to him, hence, Justin, looks at his mother to whom a child is most closed, to see what is her response. Thus he is using social referencing to make a judgement about his uncle.

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.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
