KUSA - In most large families, younger siblings don't always get as much individualized attention as needed. A new study suggests that quality interactions with older siblings may help alleviate some of that "lack of attention."

Previous research has suggested that children from large families perform worse on vocabulary, IQ and other academic tests compared to those from smaller families. Such findings are based on the principle that these children usually don't get as much attention, time and resources from their parents.

Researchers at the University of Toronto wanted to understand whether having an older sibling could affect academic test scores and found that there was, in fact, a relationship. 

According to the study, younger siblings from large families, who had more interaction with their older siblings, performed better on a vocabulary test compared to those who has less interaction with their brothers and sisters.

Further research needs to be done to understand if sibling interaction causes higher academic scores rather than just a loose correlation.
