This study explored whether a Brief Form of the California Odor Learning Test 3 (COLT), an olfactory analog of the newly released Brief Form of the California Verbal Learning Test (CVLT 3), could retain the ability of the COLT to detect odor memory dysfunctions observed in normal aging. 52 participants, 28 young (18-30 years old) and 24 old (65 years of age and older), were administered the Brief Forms of the CVLT 3 and the COLT 3. Results indicated poorer performance in immediate and delayed odor recall in older than in younger adults. Poorer odor recognition memory performance in older adults than in younger adults was detected. This study suggests that the Brief Form of the COLT can detect differential odor learning and memory between young and older adults. Thus, the current brief test holds promise as a measure that can be incorporated into studies that demand a brief, non-invasive test capable of detecting impairment in olfactory function.
本研究探讨了加利福尼亚嗅觉学习测试3简版（COLT），即新发布的加利福尼亚言语学习测试简版（CVLT 3）的嗅觉类似物，是否能够保留COLT检测正常衰老中观察到的嗅觉记忆功能障碍的能力。52名参与者，28名年轻人（18 - 30岁）和24名老年人（65岁及以上），接受了CVLT 3简版和COLT 3简版测试。结果表明，老年人在即时和延迟嗅觉回忆方面的表现比年轻人差。检测到老年人的嗅觉识别记忆表现比年轻人差。本研究表明，COLT简版能够检测出年轻人和老年人之间不同的嗅觉学习和记忆。因此，当前的简短测试有望作为一种测量方法，纳入需要简短、非侵入性测试以检测嗅觉功能障碍的研究中。
