Recent experimental and neuropsychological theorizing suggest that att
ention may be divided into separable domains. These are organized alon
g the dimensions intensity and selectivity, comprising the attention d
omains of alertness, sustained attention, selective or focused attenti
on, and divided attention. There is strong evidence that differently l
ocalized brain damage leads to specific impairments within these atten
tion domains. Efficacy studies on retraining methods after attention i
mpairments show that the intensity aspects of attention in particular
have to be trained in a highly specific way so as not to risk further
impairment. In this paper, a taxonomy of attention domains and apperta
ining tasks is presented. These tasks serve as instruments to assess s
pecific attention impairments in the individual patient, to help the n
europsychologist plan therapeutic measures, and to evaluate their effi
cacy.
