Vigilance and iconic memory in children at high risk for alcoholism.
OBJECTIVE Previous studies report reduced visual event-related potential (ERP) amplitudes in young males at high risk for alcoholism. These findings could involve difficulties at several stages of visual processing. This study was aimed at examining vigilance performance and iconic memory functions in children at high risk or low risk for alcoholism. METHOD Sustained vigilance and retrieval f...

15 صفحه اولVisual P3a in male subjects at high risk for alcoholism.
BACKGROUND Voltage of the P300 component of event-related potentials (ERPs) has been proposed as a phenotypic marker of risk for alcoholism. P3a elicited by intrusive events is important in the context of deficits in inhibition found during psychophysiological and behavioral evaluations in children of alcoholics. METHODS ERPs were recorded from a group of adult children of alcoholics (n = 26)...
متن کاملMismatch negativity in subjects at high risk for alcoholism.
BACKGROUND Evidence from P300 studies in both alcohol-dependent and high-risk (HR) individuals suggests that the reduced P300 amplitudes that often characterize these individuals may reflect a deficit in inhibition (hyperexcitability) in the central nervous system. In this context, the mismatch negativity (MMN) was investigated in the male and female HR offspring of alcohol-dependent fathers an...
متن کاملMiddle-latency auditory evoked potentials in children at high risk for alcoholism.
PURPOSE In the course of a high-risk study for alcoholism, the middle-latency auditory evoked potentials (MAEPs) of children of alcoholics were explored. MATERIAL AND METHODS A series of auditory clicks (0.1 ms, 60 dB SL, 1.1/s) were used to record the Pa and Pb peaks of the MAEPs in 15 children of alcoholics with a multigenerational family history of alcoholism, and 17 control subjects, rang...
