Why do brothers and sisters who grow up in the same house have different brains?

Which Sibling Has Highest IQ According To Science: It is often seen between brothers and sisters growing up in the same house that their intelligence, way of thinking and behavior are quite different from each other. The question of why this difference occurs despite similar upbringing, similar resources and similar environment has been attracting psychologists and researchers for a long time. Now research has started to explain this mystery to some extent, where birth order also seems to play an important role.

Which child is more intelligent?

It is often believed that the first child is the most intelligent. There is some scientific basis behind this belief. According to a study by the University of Edinburgh, the thinking ability of first born children was found to be more developed than that of their younger siblings. Similarly, economists from the University of Edinburgh, Analysis Group and the University of Sydney analyzed data from the American Bureau of Labor Statistics. In this research, it was found that first born children start being ahead of their siblings in intelligence tests from the age of one year.

What are the reasons for this difference?

Many reasons have been given behind this difference. The first reason is the full attention of the parents. When the first child is born in the family, he gets full time and guidance from the parents. Research at the University of Edinburgh also revealed that even if parents provide equal emotional support to all children, the first child gets more help in tasks related to mental development.

effect of teaching

The second important reason is the effect of teaching. The elder child often teaches things to his younger siblings. This process further strengthens his own knowledge and understanding. That is, by teaching, his learning ability becomes better. However, this does not mean that the middle or youngest child is less intelligent. Sometimes young children excel in different abilities, such as creativity, social understanding or openness to new ideas.

Effect of change in parenting

Another important aspect is change in parenting. The behavior of parents changes slightly with every child. As experience increases, their style also changes, which unknowingly affects children’s self-confidence, thinking and personality. The most important thing for parents is that they should not keep their children tied to any one identity. Labels like ‘she is the smartest’ or ‘she is the naughty’ have a deep impact on the minds of children and they start seeing themselves in the same light. Instead, it is more important to focus on the efforts, hard work and progress of the children.
