The study reported here examined the effects of experimentally induced minor illnesses (colds and influenza) on the efficiency of human performance. Influenza impaired the ability to detect and respond quickly to stimuli appearing at irregular intervals, but had no effect on a task requiring hand-eye coordination. In contrast to this, colds impaired(More)
In two studies experimentally induced colds slowed the speed of response in a serial reaction task. Responding was also slower during the incubation period of the illness, which shows that performance on such a task may be used to predict subsequent illness. Volunteers who had no significant clinical illness, but who had a significant rise in IgG following(More)
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(More)
Four experiments were carried out to investigate the effects of experimentally-induced colds on various aspects of memory of 27, 47, 39, and 30 adults. Free recall, digit span, and retrieval from semantic memory were unaffected by having a cold. Immediate recognition of important information from a story was impaired in subjects with colds, which suggests(More)
