Parent reading to child

Good news for parents who read with their infant- and toddler-aged children: It’s making a big difference.

Even more so, children “with sensitizing alleles on the dopamine receptor 2 and serotonin transporter genes” — a.k.a., genetic variants that could affect their learning ability — “fared [just] as well” on a vocabulary-comprehension test at age 3 “as children without these alleles when shared reading occurred.”

“We found thatreading with very young childrencan be quite powerful and really makes a difference in a child’s development, particularly with children who may be vulnerable to developmental delays,” lead study author Manuel Jimenez, a pediatrician and assistant professor, told Rutgers.

The study looked at 1,772 children — 31 percent of them with mom-reported daily reading — and saw that regularly reading to them as early as age 1 “was strongly associated with child Peabody Picture Vocabulary Test scores.”

“Biological measures give us another way to identify children for which interventions, in this case reading, may have the greatest benefit,” pediatrician and professor Daniel Notterman toldRutgers.

“Although there is already evidence ofthe positive effects of shared reading, this study provides additional verification and a more quantitative picture of the link between a child’s environment, biological makeup and development,” he added.

Similarly, studies in the past have found links between parent-toddler interaction andreading print books togetheras opposed to e-books,less negative behavior associatedwith shared reading, and more.

“The bottom line is that children respond positively to shared reading at an early age and doing so is one way to improve language skills for all children,” Jimenez toldRutgersof the November study.

“In a supportive environment, children who may be genetically at-risk, do just as well as their peers,” he added.
