Priming Deficiency in Male Subjects at Risk for Alcoholism: The N4 During a Lexical Decision Task

Visual 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)...

Evoked gamma band response in male adolescent subjects at high risk for alcoholism during a visual oddball task.

This study investigates early evoked gamma band activity in male adolescent subjects at high risk for alcoholism (HR; n=68) and normal controls (LR; n=27) during a visual oddball task. A time-frequency representation method was applied to EEG data in order to obtain stimulus related early evoked (phase-locked) gamma band activity (29-45 Hz) and was analyzed within a 0-150 ms time window range. ...

Syllable priming with pseudowords in the lexical decision task.

This study investigated the processes underlying the effect of masked syllable priming in French with pseudoword primes and word targets. Two lexical-decision task (LDT) experiments examined whether the syllable priming effect depends on syllable frequency and might rely on a general abstract structure. The results of Experiment 1 revealed an inhibitory priming effect, with pseudoword primes an...

Auditory P3a deficits in male subjects at high risk for alcoholism.

BACKGROUND Substantial evidence indicates that alcoholism is biologically mediated by a genetic predisposition. As the decreased P300 (P3b) event-related brain potential component does not recover with prolonged abstinence, it is unlikely to be related to drinking history but is more likely to be genetically influenced. This is supported by findings that P3b amplitudes are reduced in subjects a...
