This study examined electromyogram (EMG) and skin conductance level (SCL) as mediators of neuropsychological test performance of alcoholics. Alcoholics and controls with high EMG performed less well than low EMG subjects on 12 measures of neuropsychological performance. For SCL, the alcoholics and controls in the Low Group did not differ from those in the High Group on any measure. Analyses that used information intake (Low EMG and High SCL) and rejection (High EMG and Low SCL) information postures (IPs) demonstrated that the intake group outperformed the rejection group on 10 neuropsychological measures. Subjects with intake IPs reported more stimulation, concentration, and interest during the tasks than did subjects with rejection IPs. Results suggest that IPs can be used to identify alcoholics with neuropsychological deficits.
本研究考察了肌电图（EMG）和皮肤电导水平（SCL）作为酗酒者神经心理测试表现的中介因素。在12项神经心理表现指标上，肌电图高的酗酒者和对照组比肌电图低的受试者表现更差。对于皮肤电导水平，低分组的酗酒者和对照组在任何指标上与高分组均无差异。使用信息摄入（低肌电图和高皮肤电导水平）和拒绝（高肌电图和低皮肤电导水平）信息姿态（IPs）的分析表明，摄入组在10项神经心理指标上的表现优于拒绝组。与拒绝信息姿态的受试者相比，采用摄入信息姿态的受试者在任务过程中报告有更多的刺激感、注意力更集中且兴趣更高。结果表明，信息姿态可用于识别有神经心理缺陷的酗酒者。
