Wikipedia: attention span

Attention span is the amount of time a person can concentrate on a single activity. The ability to focus one's mental or other efforts on an object is generally considered to be of prime importance to the achievement of goals. People usually have a longer attention span when they are doing something that they enjoy.

In a study of 2,600 children ages 1 to 3 published in 2004, a team of researchers from University of Washingtonfound that early exposure to television may have a negative impact on attention span.^[1][2] It has also been suggested that internet browsing can have a similar effect. ^[3]
