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 they were less able to follow the theme of the story. In contrast to this, volunteers with colds had better recognition of information from a story learned prior to the virus challenge.
