Very-low-birth-weight children (16 with and 45 without attention deficit/hyperactivity disorder) were matched to term-born controls (27 with attention deficit/hyperactivity disorder and 30 without) according to age, intelligence, and social class of their parents. The children were screened for motor, visual, and mental disabilities. The general aim of the study was to evaluate information processing stages using the additive factor method of Sternberg. The tasks consisted of computerized visual-motor letter recognition and arrow detection tasks. The tasks elicited similar prolongations of response times, increases in standard deviation of the response times, and increased error rates in the four groups. We conclude that very-low-birth-weight and control children do not differ in their information processing stages.
