我们对238名30岁到94岁的成年人的纵向数据进行了多变量随机效应分析，他们在20年的时间里进行了五次词汇测试，以考察(A)词汇提取的不同测试所表现出的词条和词汇提取之间的关系，以及(B)成年后词汇加工的变化。这项研究记录了与年龄相关的词汇提取下降的不同特征，这些下降由任务需求、性别、教育和潜在的认知技能决定。需要提取独特词汇项目的任务(波士顿命名测试和动作命名测试)产生了与年龄相关的显著下降，随着年龄的增长，下降速度变得更快，这与允许提取各种词汇项目的任务不同。研究结果支持词条和词位提取在单词产生过程中的级联过程。
We conducted multivariate random-effect analyses on longitudinal data from 238 adults, ranging in age from 30 to 94, who were tested on five lexical tests over a period of 20 years to examine (a) the relations between lemma and lexeme retrieval as manifested in different tests of lexical retrieval and (b) changes in lexical processing during older adulthood. This study documents differing profiles of age-related decline in lexical retrieval determined by task demand, gender, education, and underlying cognitive skills. The tasks that required retrieval of unique lexical items (Boston Naming Test and Action Naming Test) yielded significant age-related decline that became more rapid in older age, distinguishing them from tasks that allowed for the retrieval of various lexical items. Findings support a cascaded progression of lemma and lexeme retrieval during word production.
