Talkative Parents May Boost Child’s IQ

Interesting new research suggests exposure to large amounts of adult speech may enhance a child’s cognitive skills. The major new study, led by scientists at the University of York, identified a link between kids who heard high amounts of adult speech and their nonverbal abilities such as reasoning, numeracy and shape awareness.

Investigators used a novel research methodology that included fitting tiny audio recorders into the clothing of pre-schoolers aged two to four. Subsequently, they recorded the experience of 107 children and their interactions with parents and other caregivers in the home environment over three days for up to 16 hours per day.

Parents were also asked to complete activities with their children involving drawing, copying and matching tasks designed to test their child’s cognitive skills.

Lead author of the study, Katrina d’Apice, a PhD student from the University of York’s Department of Education, explains, “Using the audio recorders allowed us to study real-life interactions between young children and their families in an unobtrusive way within the home environment rather than a lab setting.”

The study, “A Naturalistic Home Observational Approach to Children’s Language, Cognition, and Behavior,” appears in the journal, Developmental Psychology.

“We found that the quantity of adult spoken words that children hear is positively associated with their cognitive ability. However, further research is needed to explore the reasons behind this link — it could be that greater exposure to language provides more learning opportunities for children, but it could also be the case that more intelligent children evoke more words from adults in their environment.”

The researchers also found that high-quality adult speech may have benefits for children’s linguistic development, as children in the study who interacted with adults who used a diverse vocabulary knew a greater variety of words themselves.

Researchers also analyzed the recordings to look at the impact different parenting styles might have on the children’s behavior.

d’Apice and her colleagues found that positive parenting — where parents are responsive and encouraging of exploration and self-expression — was associated with children showing fewer signs of restless, aggressive and disobedient behaviors.

“This study is the largest naturalistic observation of early life home environments to date,” elucidates Professor Sophie von Stum, the study’s senior author.

“We found that the quantity of adult spoken words that children were exposed to varied greatly within families. Some kids heard twice as many words on one day as they did on the next.

“The study highlights the importance of treating early life experiences as dynamic and changeable rather than static entities — approaching research in this way will help us to understand the interplay between environmental experiences and children’s differences in development.”
