我们从三个不同地点的多个中大型参与者样本中收集了类别流畅性数据：纽约大学老龄化和痴呆症中心、俄勒冈州卫生服务老龄化和痴呆症研究中心以及阿尔伯特·爱因斯坦医学院的爱因斯坦老龄化研究。通过计算每个参与者产生的类别成员的平均相对频率（例如，典型性）来分析这些数据。阿尔茨海默病（AD）患者回忆起更少的非典型成员的共同分类类别比老年对照组。此外，在任务持续期间，AD患者产生项目的概率以更大的速度下降，而老年对照组则没有。根据序贯抽样模型，后者的结果意味着，AD患者搜索记忆的速度必须比老年人控制的搜索速度慢。（PsycInfo数据库记录（c）2023阿帕，保留所有权利）
We collected category fluency data from several moderate-to-large samples of participants at three different sites: the New York University Aging and Dementia Center, the Oregon Health Services Aging and Dementia Research Center, and the Einstein Aging Study at the Albert Einstein College of Medicine. These data were analyzed by calculating the average relative frequency (eg, typicality) of the category members generated by each participant. Alzheimer's disease (AD) patients recalled fewer atypical members of common taxonomic categories than did the elderly control group. In addition, the probability of producing an item declined at a greater rate for AD patients than for the elderly control group over the duration of the task. According to sequential sampling models, this latter result implies that the rate at which AD patients search memory must be slower than the search rate of the elderly controls.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
