The validity and clinical viability of Posner and Petersen's (1999) 3-factor model of attention was tested through a confirmatory factor analysis of attentional performance (Test of Everyday Attention [Robertson, I. H., Ward, T., Ridgeway, V., & Nimmo-Smith, I. (1996). The structure of normal human attention: The Test of Everyday Attention. Journal of the International Neuropsychological Society, 2, 525–534]) in a sample of 133 Chinese participants. This study served both as a cross-cultural replication of the clinical implementation of this leading theoretical model of attention, and as a more stringent test of the validity of the hypothesized attentional processes underlying human cognitive control. The results support the validity of a 3-factor model of attention consistent with that proposed by Posner and Petersen (selective attention, sustained attention, and attentional switching/control), and demonstrate that clinical assessment of neuroanatomically-distinct attentional processes using simulated real life activities is possible.
