Abstract

Using a paradigm which shows effects of inhibition of return, two experiments were carried out to examine attentional deficits in patients with Senile Dementia of the Alzheimer Type(SDAT). In experiment 1, using a continuous responding paradigm, we tested whether SDAT group shows inhibition effects. In contrast to normal group, we failed to obtain inhibition of return in SDAT group. In experiment 2, employing a cue-target paradigm, we found that both the normal and the SDAT group showed facilitatory effects of attention in short cue-target SOA conditions. These results suggest that 1) there is no indication of facilitatory attentional deficits in SDAT; 2) SDAT may have problems with inhibitory control of attention in various information processing pathways.
