已知老年人从语义一致的感官刺激的同时呈现中获得比年轻人更多。虽然这些发现令人兴奋，但它们可能不仅仅是由于多感觉处理中与年龄相关的差异。相反，增强的整合可以解释为与一般认知减慢相关的改变。这项研究利用了一个消除了大多数高阶认知处理的任务。因此，在单一感觉反应时间上没有显着差异;然而，老年人实际上比年轻人表现出更快的多感觉反应。老年人继续表现出显着更大的多感官增强比年轻的成年人。数据支持的结论是，老年人的多感官处理的差异不能解释仅仅是一般的认知放缓的影响。
Older adults are known to gain more than younger adults from the simultaneous presentation of semantically congruent sensory stimuli. Although these findings are quite exciting, they may not solely be due to age-related differences in multisensory processing. Rather, enhanced integration may be explained by alterations associated with general cognitive slowing. This study utilized a task that eliminated most high-order cognitive processing. As such, no significant differences in unisensory response times were seen; however, older adults actually showed faster multisensory responses than younger adults. Older adults continued to show significantly greater multisensory enhancement than younger adults. Data support the conclusion that differences in multisensory processing for older adults cannot be explained solely by the effects of general cognitive slowing.
