Understanding why children are different

Children differ. Some are tall, some are short. Some are loud, some are quiet. Some are happy, some sad. Some do well in school, others don’t. Why?

Understanding why children are different

Many different factors explain children’s differences in learning. For example, children who get to read many books tend to do better in learning tasks than children who have less access to books. Another example is the home environment that parents provide for their children: Kids who grow up with a lot of stimulating games and activities tend to find studying for school easier than kids who are less often engaged.
Another important factor is the genetics that children inherit from their parents. Differences in children’s learning can partly be attributed to genetic influences, a phenomenon known as heritability. Genetic influences can mimic environmental effects. For example, parents who are genetically inclined toward reading may have many books at home and also pass the genetic tendencies for reading on to their child. In this case, the access to books is a by-product of shared genetics, rather than an independent environmental cause of differences in learning.
At the Hungry Mind Lab, we use genetically sensitive study designs to disentangle genetic and environmental influences on children’s cognitive and social-emotional development.
