DESCRIPTION (provided by applicant): Spoken language comprehension is a primary means of communication for most adults, and remains so throughout the lifespan. Although older adults' language comprehension is generally good, age-related cognitive decline results in some comprehension deficits. These deficits are not simply a consequence of age-related declines in hearing acuity. The long-term goal of this research program is to find strategies that older adults can actively employ to improve their comprehension of spoken language. This will be accomplished by assessing young and older participants' comprehension of meaningful speech that varies in both speech rate (accomplished using time-compression techniques) and syntactic complexity, two manipulations that older adults are known to find differentially more difficult than their younger counterparts. Of particular interest is whether older adults' performance will improve with repeated exposure to time-compressed speech, and whether this improvement for rapid speech will aid in the comprehension of syntactically complex speech.

描述（由申请人提供）：口语理解是大多数成年人的主要沟通方式，并且在一生中始终如此。尽管老年人的语言理解能力普遍良好，但与年龄相关的认知能力下降会导致一些理解能力缺陷。这些缺陷不仅仅是与年龄相关的听力敏锐度下降的结果。该研究计划的长期目标是找到老年人可以积极采用的策略来提高他们对口语的理解力。这将通过评估年轻和年长参与者对有意义的言语的理解来实现，这些理解在语速（使用时间压缩技术完成）和句法复杂性方面有所不同，众所周知，老年人发现这两种操作比年轻人更困难。特别令人感兴趣的是，老年人的表现是否会随着反复接触时间压缩的语音而得到改善，以及这种快速语音的改善是否有助于理解句法复杂的语音。
