The present study examined whether volunteers who had recently had common colds showed impairments in mood and performance in the weeks following the illness. All volunteers (n = 24) were tested when healthy to provide baseline data for simple and choice reaction time tasks, attention and memory tasks and ratings of mood. When participants developed a cold (n = 13) they returned to the laboratory so that the illness could be verified. When they were symptom free they returned to the laboratory and repeated the procedure. They then completed the study with a final session 1 week later. Volunteers (n = 11) who remained healthy over 10 weeks were recalled as controls and also repeated the procedures. The results showed that those who had recently had colds showed few impairments in mental performance and mood. Taken together with the results of previous studies, this suggests that after-effects of viral infection are largely restricted to severe illnesses such as infectious mononucleosis and influenza. After-effects of colds may occur but these probably reflect poor learning at the time of the illness.
本研究调查了近期患过普通感冒的志愿者在患病后的几周内是否在情绪和表现方面存在缺陷。所有志愿者（n = 24）在健康时接受测试，以提供简单和选择反应时间任务、注意力和记忆任务以及情绪评分的基线数据。当参与者患上感冒（n = 13）时，他们返回实验室以便对疾病进行核实。当他们无症状时，他们返回实验室并重复该程序。然后他们在1周后进行最后一次测试，完成整个研究。10周内一直保持健康的志愿者（n = 11）被召回作为对照组，同样重复这些程序。结果表明，近期患过感冒的人在心理表现和情绪方面几乎没有缺陷。结合先前研究的结果，这表明病毒感染的后遗症在很大程度上限于严重疾病，如传染性单核细胞增多症和流感。感冒可能会有后遗症，但这些可能反映了患病时学习效果不佳。
