The family’s level of well-being in the first five years of life determines the future fate. This conclusion was reached by Canadian physiologists after analyzing the lives of more than 100 subjects.
Scientists have concluded that people raised in poor families have elevated levels of the stress hormone cortisol. It rises when necessary to save a life. If the concentration of cortisol in the body is constantly maintained, then the person will become less inclined to take risks. Thus, wealthy people tend to be more risk averse, according to a study published in PNAS…
Study specialists from Duke University (USA) showed that in children from low-income families, due to the SLC6A4 gene, which is responsible for the distribution of serotonin in the brain, the activity of the amygdala increases. This is associated with the risk of developing depression and other mental disorders.
In addition, small changes in the structure of the brain are recorded in those who grew up in wealthy families. So, in rich children, the bark is thickened in the parietal and temporal zones. These areas of the brain are responsible for visual perception and long-term memory, which are directly related to high academic performance.
This is also confirmed by numerous studies showing that the performance of children of poor people is on average lower than that of children of wealthy parents.
On the other hand, wealthy children are less prone to altruism and self-sacrifice. In the course of one of the experiments, it turned out that low-income children were more willing to donate money to the needy, while the rich preferred not to share with anyone.
