“…This evidence vindicates Das and colleagues (see Das, 1973;Das et al, 1979Kirby & Das, 1977;Kirby et al, 1996;Leong et al, 1985;Naglieri & Das, 1987;Papadopoulos, Parrila, Das, & Kirby, 1997) who envisioned intelligence as a set of independent, yet interrelated, cognitive processes. Because of its process-oriented nature, the PASS theory of intelligence fits well within an integrative framework of neuropsychological assessment (Flanagan, Alfonso, Ortiz, & Dynda, 2009) and provides direction to the intervention of reading (Hayward et al, 2008) and mathematics difficulties (Das & Janzen, 2004). The celebration of PASS theory's 40th anniversary (Das, 1973) should mark the starting point for new studies examining the role of intelligence on achievement and bridge the gap between theory and practice.…”
