According to Kids Growth, the attention span of a child or teen who is actively trying to pay attention is 3 to 5 minutes for every year of the child's age. As a result, a 13-year-old has an attention span between 39 and 65 minutes, while a 16-year-old is capable of paying attention for 48 to 80 minutes.
A number of factors affect the attention span of teens, according to Kids Growth. For example, a child with attention deficit disorder has a shorter attention span than the average teen. The amount of time a teen sits and watches TV or plays video games is not an accurate measure of the length of their attention span.
Statistic Brain, which gets its stats from sources such as the U.S. National Library of Medicine and the National Center for Biotechnology Information, states that technology has significantly lowered the average attention span of people in general, including teens. The average attention span of people was 8 seconds in 2013. This is compared to the average attention span of 12 seconds in 2000. Statistics suggest that the average attention span of a goldfish is 9 seconds, which indicates that the average person had an attention span shorter than that of a goldfish in 2013.
