Contingent negative variation and psychopathology: frontal-central distribution, and association with performance measures.

摘要: Central and frontal contingent negative variation (CNV) were studied in psychiatric patients - schizophrenics, nonschizophrenic psychotics, schizotypics, neurotics (according to DSM III) a normal control group. The early CNV components postimperative negativity significantly different schizophrenic contrast with their scores on some attentional performance tests. Only the central was correlated severity of diagnosis, but multivariate analyses indicated importance this respect. Topographical characteristics also seem indicative disturbance. These results are integrated composite index for further study. general trend showed moderately high degree shared variance measures, not regard other found across diagnostic groups. No significant associations between measures affective social functioning, Eysenck's personality dimensions.
