This study explored the association of negative symptoms and reaction time. Negative symptoms were specifically associated with reaction time slowing and variability in schizophrenics, but not in affective disorders. The finding of specificity did not extend to other measures of the deficit syndrome nor to motor performance. An abbreviated version of the negative symptom scale was especially effective in separating groups.
本研究探讨了阴性症状与反应时间之间的关联。阴性症状与精神分裂症患者的反应时间减慢及变异性存在特定关联，但在情感障碍患者中并非如此。特异性这一发现并未扩展至缺陷综合征的其他测量指标，也未扩展至运动表现。阴性症状量表的简化版在区分不同组时特别有效。
