“…To date, however, this type of research has not been undertaken in the area of attention. Thus, in the literature, researchers adopting the information processing approach prefer to use specifically defined experimental tasks to study the effects of brain damage on attention (e.g., Sergeant & Scholten, 1983;Shum, McFarland, Bain, & Humphries, 1990a), and clinicians continue to use conventional psychological tests to diagnosis attentional problems in braindamaged patients (e.g., Picano, Klusman, Hornbostel, & Moulton, 1992;Shum, McFarland, & Bain, 1990b).…”
