有部分亲戚的情况是共享(例如,属性的房子)。这个环境的关系代表了0.25 – -0.35的品种在青少年的智商。逾期不成熟,在一些研究(0)。有一个类似的影响几个其他精神属性。这已经不是调查的影响强烈的情况下,例如,在破坏家庭。
There are a few family impacts on the IQ of kids, representing up to a part of the difference. In any case, adoption researches demonstrate that by maturity supportive kin aren’t further comparable in IQ than outsiders, whereas grown-up full kin demonstrate an IQ connection of 0.6. Routine twin experiments strengthen this example: monozygotic (indistinguishable) twins brought up independently are exceedingly comparative in IQ (0.86), further so than dizygotic (brotherly) twins brought up jointly (0.6) and substantially more than supportive kin (~0.0). Notwithstanding, a few investigations of twins raised separated discover a noteworthy imparted ecological impact, of no less than 10% moving into overdue maturity. JR Harris proposes that this may be because of prejudicing presumptions in the procedure of the traditional twin and appropriation learnings.
There are parts of situations that relatives have in as something to be shared (for instance, attributes of the house). This imparted relations environment represents 0.25-0.35 of the variety in IQ in youth. By overdue immaturity it is little (0 in a few studies). There is a comparable impact for a few other mental attributes. This has not investigated the impacts of intense situations, for example, in damaging families.
