“…Historically, batteries that incorporate perceptual and visual-motor skills are described as consisting of a limited number of independent 'psychomotor' factors (e.g., Boyle & Ackerman, 2004;Fleishman & Hempel, 1956;Guilford, 1958) that, in turn, overlap with a more general cognitive factor (Carretta & Ree, 1997;Chaiken, Kyllonen, & Tirre, 2000;Ree & Carretta, 1994). Despite this insight, relatively few of the existing multi-test performance batteries have specifically included measures of low-level sensory functions, such as visual acuity, Contrast Sensitivity, and depth perception, despite the critical role that basic visual sensory abilities play in most human performance contexts, and evidence that they modulate a number of other higher-level perceptual and cognitive abilities (Daffner et al, 2013;Skeel, Schutte, van Voorst, & Nagra, 2006).…”
