A technique for on-line classification of evoked potentials into two groups according to subjective interpretation of the stimulus.
A technique is described for on-line classification of evoked potentials (EPs) into distinct groups for separate averaging according to a criterion available after the beginning of the EPs. It is suitable for analysing psychophysiological correlations (relationship between EPs and subjective perception). The system consists of a slightly modified NTA 512 B (Hungarian) average response computer (however, any CAT-computer-like device can be used in a similar way) and of an additional device. It can be used in all cases when the number of subjective judgements according to which EPs have to be classified can be limited to two (or three, when, by slightly changing the system, all quarters of memory are used).
