The researchers found that children who received more attention and nurturing at home tended to have higher IQs. Children who were more cognitively stimulated performed better on language tasks, and those nurtured more warmly did better on memory tasks.

Many years later, when the kids had entered their teens, the researchers took MRI images of their brains and then matched them up with the records of how warmly nurtured the children had been at both four and eight years old. They found a strong link between nurturing at age four and the size of the hippocampus—a part of the brain associated with memory—but found no correlation between nurturing at age eight and the hippocampus.
