ABSTRACT
Attention refers to a class of intensive and selective processes (van Zomeren and Brouwer, 1994; see the models proposed by Posner and Petersen in 1990, Norman and Shallice in 1986, Baddeley in 1986, Shiffrin and Schneider in 1977, and described in the previous chapters) and we usually base our assessment proposal upon a classification of three subtypes of attention (selective attention, divided attention, sustained attention) all derived from clinical and experimental assessment, functional imaging, and cognitive event-related potentials. Consequently the clinical assessment of attention would embrace the examination of each attentional process: only in this way is it possible to delimit the specific pattern of attentional disorders in each patient and suggest an individualized programme of neuropsychological rehabilitation. Many non-computerized tests have been designed to assess selective attention, divided attention and sustained attention.
