Studies of experimentally induced respiratory infections and illnesses showed that influenza impaired performance on a visual search task but had no effect on a simple motor task, whereas colds impaired the motor task but not the search task. The effect of influenza on the search task was observed in both volunteers with significant clinical symptoms and volunteers who were shown, by virological techniques, to be infected but who had no significant clinical illness. Performance was also impaired during the incubation period of this illness, which confirms that subclinical influenza virus infections can have behavioural effects. In contrast to influenza, the effects of colds were restricted to volunteers who had significant clinical symptoms, and the impairments in performance were observed only when the symptoms were apparent.
对实验性诱发的呼吸道感染和疾病的研究表明，流感会损害视觉搜索任务的表现，但对简单运动任务没有影响，而感冒会损害运动任务，但对搜索任务没有影响。在有明显临床症状的志愿者以及通过病毒学技术显示已被感染但无明显临床疾病的志愿者中，均观察到了流感对搜索任务的影响。在这种疾病的潜伏期，表现也会受到损害，这证实了亚临床流感病毒感染可能会产生行为影响。与流感不同，感冒的影响仅限于有明显临床症状的志愿者，并且只有在症状明显时才会观察到表现受损。
