Scary TV's impact on kids is overstated, say psychologists

A recent study by University of Sussex researchers suggests that the impact of scary TV on children's internalizing emotions is smaller than previously thought. Overall, children show very little sign of increased anxiety or fear, but some may be more affected due to individual differences in anxiety levels.
