Abstract

We investigate the decision making ability of subjects with a history of long-term intoxicant (alcohol) consumption in relation to short-term visual memory using P3 amplitudes obtained from single trial visual evoked potential (VEP) signals. This is made possible by means of digital filtering and principal component analysis (PCA). The results show a significantly lower P3 amplitude for these subjects as compared to controls. This electroencephalogram based analysis conforms with the common knowledge that long-term alcohol use causes permanent and negative residual effects on decision making ability related to short-term visual memory
