title: Developmental normative data on the test of variables of attention (T.O.V.A.).
abstract: Developmental normative data for 775 children aged 6-16 are presented for the Test of Variables of Attention (T.O.V.A.), a 23-minute fixed-interval visual Continuous Performance Test with minimal language demands and no left-right discrimination. The target is presented on 22.5% and 77.5% of the trials during the first and second halves, respectively, T.O.V.A. indices include omission and commission errors, response time means and standard deviations, and anticipatory responses. Attention and impulse control developed in a non-linear manner, changing rapidly in early childhood and leveling off during later childhood and adolescence.
