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 (e.g., 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.
纽约大学衰老与痴呆症中心、俄勒冈健康服务衰老与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衰老研究。通过计算每个参与者生成的类别成员的平均相对频率（例如，典型性）来分析这些数据。与老年对照组相比，阿尔茨海默病（AD）患者回忆起的常见分类类别中非典型成员较少。此外，在任务过程中，AD患者生成一个项目的概率下降速度比老年对照组更快。根据顺序抽样模型，后一个结果意味着AD患者搜索记忆的速度一定比老年对照组的搜索速度慢。
