A normative study of 230 children from Sydney pre-schools and primary schools (aged 3-7 years) was carried out using a Continuous Performance Test of Vigilance (CPT), the Draw-a-Line Slowly test (DALS) for motor inhibition, and the Sprague Ballistographic Chair for motility. The study demonstrated a clear age development in capacity for sustained attention (vigilance) and in motor inhibition between 4 and 6 years of age, in normal children. Correlations between components of the CPT, Mean Reaction Time (MRT), and the DALS test were shown suggesting a need for further multivariate studies. Sex differences were not found for the CPT, or DALS tests, but were shown for Chair Score and for motor components of the DALS test (DALO and DALF), for which boys scored higher motility scores and faster DALO and DALF scores.
