title: Time estimation by hyperactive and normal children.
abstract: In two studies [a pilot (12 7- to 10-yr.-olds) and a main study (100 8- to 12-yr.-olds)] hyperactive and normal children were compared on the ability to estimate time intervals ranging from 7 to 60 sec. The differences between estimated and elapsed time were larger for hyperactives than for normals, with the differences between the groups increasing with the length of the interval to be estimated.
