[Peculiarities of attention in families with schizophrenia: correlation between psychological and neurophysiological characteristics].
A relationship between neurophysiological and psychological characteristics of attention was studied in 18 patients with schizophrenia and their 34 mentally healthy relatives: parents and siblings (20 subjects) and children (14 subjects). In patients, a decrease of P300 auditory evoked potentials significantly correlated with disturbances of attention stability and volume as well as characteristics of involuntary attention. At the same time, in the groups of relatives the anomalies of attention stability and attention in conditions of prolonged concentration were positively related to P300 latency.
