TV's impact on toddlers and how it influences the processing abilities - Video

Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviors, such as being disengaged and disinterested in activities, seeking more intense stimulation in an environment, or being overwhelmed by sensations like loud sounds or bright lights, according to data from researchers at Drexel’s College of Medicine published today in the journal JAMA Pediatrics.

According to the researchers, children exposed to greater TV viewing by their second birthday were more likely to develop atypical sensory processing behaviors, such as “sensation seeking” and “sensation avoiding,” as well as “low registration” — being less sensitive or slower to respond to stimuli, such as their name being called, by 33 months old.

Sensory processing skills reflect the body’s ability to respond efficiently and appropriately to information and stimuli received by its sensory systems, such as what the toddler hears, sees, touches, and tastes.

The team pulled 2011-2014 data on television or DVD-watching by babies and toddlers at 12- 18- and 24-months from the National Children’s Study of 1,471 children (50% male) nationwide. Sensory processing outcomes were assessed at 33 months using the Infant/Toddler Sensory Profile (ITSP), a questionnaire completed by parents/caregivers, designed to give insights on how children process what they see, hear and smell, etc.

The findings suggest:

At 12 months, any screen exposure compared to no screen viewing was associated with a 105% greater likelihood of exhibiting “high” sensory behaviors instead of “typical” sensory behaviors related to low registration at 33 months

At 18 months, each additional hour of daily screen time was associated with 23% increased odds of exhibiting “high” sensory behaviors related to later sensation avoiding and low registration.

At 24 months, each additional hour of daily screen time was associated with a 20% increased odds of “high” sensation seeking, sensory sensitivity, and sensation avoiding at 33 months.

The findings add to a growing list of concerning health and developmental outcomes linked to screen time in infants and toddlers, including language delay, autism spectrum disorder, behavioral issues, sleep struggles, attention problems and problem-solving delays.
