Child-LedFor this type of play, a parent let the child take the lead—waiting until he or she showed interest in a certain toy and then engaging. “The responsive parents were sensitive to their children's interests and then supported their attention,” Chen Yu, lead study author, said. “We found they didn't even really need to try to redirect where the children were looking.”According to the scientist, this type of play affected a child’s attention most positively: Once a parent and child paid attention to the same toy for more than 3.6 seconds, the child was more likely to continue to focus on that item, even when the caregiver directed attention somewhere else. Parent-Led In this play-type parents tried to control their child’s interest. They held out a certain toys and named the objects, according to Yu. But the plan backfired. “You can actually see the children’s eyes wandering to the ceilings or over their parents’ shoulders—they’re not paying attention at all.” Low-Engagement Here, parents sat back, didn’t play along or looked somewhere else (e.g. at a smartphone or television) during playtime. Unsurprisingly, this was the worst play-type for attention span development. In fact, researchers found children in low-engagement play families paid attention only a fourth of the amount of time of the families who engaged in child-led play. “When you’ve got a someone who isn’t responsive to a child’s behavior,” Yu said, “it could be a real red flag for future problems.” And while it might not seem like a big issue how long a baby's attention span is, Yu explained that research has shown that children who exhibit a longer attention span as an infant do better in school later in life. What do YOU think, parents? Are YOU fully in the moment when playing with your baby, or does the phone keep luring your in from time to time?
