Indian University study finds infant attention span suffers when parents’ eyes wander during playtime

Eye-tracking study first to suggest connection between caregiver focus and key cognitive development indicator in infants

BLOOMINGTON, Ind. -- Caregivers whose eyes wander during playtime -- due to distractions such as smartphones or other technology, for example -- may raise children with shorter attention spans, according to a new study by psychologists at Indiana University.

The work appears in the journal Current Biology and is the first to show a direct connection between how long a caregiver looks at an object and how long an infant’s attention remains focused on that same object.

"Caregivers who seem distracted or whose eyes wander a lot while their children play appear to negatively impact infants' burgeoning attention spans during a key stage of development."

"Historically, psychologists regarded attention as a property of individual development," Smith said. "Our study is one of the first to consider attention as impacted by social interaction. It really appears to be an activity performed by two social partners since our study shows one individual's attention significantly influence another's."

Parents and children played together in an environment that closely resembled a typical play session at home or day care. The technology also allowed the parents and children to play with physical toys. A typical eye-tracking study of children would involve manipulating objects on a screen.

Caregivers were given no instructions before engaging with children to ensure the psychologists got an unfiltered view of their interactions.
Generally, Yu said, caregivers fell into two major groups: those who let the infants direct the course of their play and those who attempted to forcefully guide the infants' interest toward specific toys. The caregivers who were most successful at sustaining the children’s attention were those who "let the child lead." These caregivers waited until they saw the children express interest in a toy and then jumped in to expand that interest by naming the object and encouraging play.

"The responsive parents were sensitive to their children's interests and then supported their attention," Yu said. "We found they didn't even really need to try to redirect where the children were looking." The gains in attention for children in this group were significant. In cases where infants and caregivers paid attention to the same object for over 3.6 seconds, the infant’s attention lingered 2.3 seconds longer on average on the same object even after the caregiver's gaze turned away. This extra time works out to nearly four times longer compared to infants whose caregivers' attention strayed relatively quickly.

A number of other studies tracking the influence of sustained attention in children from ages 1 through grade school show consistently that longer attention spans at an early age are a strong predictor of later achievement. "Showing that what a parent pays attention to minute by minute and second by second actually influences what a child is paying attention to may seem intuitive, but social influences on attention are potentially very important and ignored by most scientists," said Sam Wass, a research scientist at the University of Cambridge whose commentary on the study appears in the same journal. "Chen Yu and Linda Smith's work in this area in recent years has been hugely influential."

The shortest attention span by children were observed when caregivers displayed extremely low engagement with children while playing. These distracted caregivers tended to sit back and not play along, or simply look elsewhere during the exercise. The point of the study is: "When you’ve got someone who isn't responsive to a child's behavior," Yu said, "it could be a real red flag for future problems."
