OK. According to non-meme based psychology, there are two major developmental factors - genes and environment, your parents and your neighborhood, nature and nurture. Leaving leaving genes aside, environmental factors consists of conditioning - social, cultural, of personal experiences and of chance events. There is nothing but conditioning and nutrition that accounts for a development. The conditioning is vastly complex and highly interrelated, but it boils down to the variety and 'intencity' of experience. Common sense tells us that a brain is a muscle - it must be trained and nourished. Any impoverishment results it failure to develop appropriate habits and skills, which later will handicap one's performance compared to the members of favourable social classes. The point is, any external causes, such as developmental disorders aside, poverty leaves one developmentaly delayed due to restricted, repetitive behavior and wrong conditioning. In some Eastern societies, like Indian and of most Buddhist counties, with emphasis on community and family rather than individuality and competition, the effect of poverty is less dramatic. Poor of India or Nepal or Cambodia are incomparable better that those of Russia, which is a social shithole, famous of its ignorance and cruelty amongst its poor.
