This study was designed to test and extend previous reports of differences in autonomic responsivity between offspring of schizophrenic patients and control subjects. In specific, greater galvanic skin response (GSR) to stimuli and quicker GSR recovery have been reported in high-risk children. In the present study we found no evidence of autonomic...

Subjects were examined with a battery of protocols based on principles of experimental psychology and designed to measure motor control, perceptual-motor coordination, attention, learning, and memory. Differences between index and control subjects were found on the mirror-drawing protocol, reflecting visual-motor coordination, and the distractibili...

... Motor impairment of coordination and balance may become more striking in children with high schizophrenia risk (166)(167)(168). Additionally, high risk children may display learning difficulties in attention, concentration, memory, and thought as well as behavioral and mood dysfunctions such as increased aggression, problematic interpersonal relations, social isolation, low self-esteem, offending behaviors, poor affective control, and depression (152,153,162,(169)(170)(171)(172)(173)(174)(175)(176). ...
... Genetic factors are known to play an important role in the appearance of schizophrenia. Data on impairments of emotional processes in the healthy relatives of patients [23,28] suggest that the deficiency in processing emotional information, along with other anomalies in the cognitive EEG correlates of impairments in the processing of emotiogenic information which might reflect a genetic predisposition to schizophrenia were sought by studying the dynamics of EEG rhythm powers on presentation of neutral and emotional words in 36 patients with schizophrenia, 50 of their unaffected firstdegree relatives, and 47 healthy subjects without any inherited predisposition to psychoses. In controls, passive hearing of neutral words produced minimal changes in cortical rhythms, predominantly in the form of increases in the power levels of slow and fast waves, while perception of emotional words was accompanied by generalized reductions in the power of the α and β 1 rhythms and regionally specific suppression of θ and β 2 activity. ...
