The Clinical Neuropsychology of Attention in School-Aged Children

100 children from the north-east of England, aged between 7 and 13 years of age, completed an assessment of intellectual ability and an attention battery based on the work of Mirsky, Anthony, Duncan, Ahearn, & Kellam (1991). Factor analysis was generally supportive of the Mirsky et al. (1991) model. Replication of the adult model produced the same four factors: sustain, encode, focus-execute and shift. Replication of the child model produced a three-factor model in which the encode and focus-execute factors combined. An extended model resulted in the introduction of a new factor labelled errors of processing. The scores on attention factors were found to have a reasonable level of independence from intellectual ability.
