Babies and toddlers exposed to television or video viewing may be more likely to exhibit atypical sensory behaviours, 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, warned a study.

According to researchers at Drexel University, children exposed to greater TV viewing by their second birthday were more likely to develop atypical sensory processing behaviours, 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.
