One focus of the authors is the seemingly unique effect of television on children under age two.
Although research clearly demonstrates that well-designed, age-appropriate, educational television
can be beneficial to children of preschool age, studies on infants and toddlers suggest that
these young children may better understand and learn from real-life experiences than they do
from video. Moreover, some research suggests that exposure to television during the first few
years of life may be associated with poorer cognitive development.
