In two published studies, we used a variant of Neely's (1977) lexical decision paradigm to study shifts of attention and automatic lexical activation in nondemented individuals with Parkinson's disease (McDonald, Brown, & Gorell, 1996; Spicer, Brown, & Gorell, 1994). Arnott and Chenery (in press) noticed differences between Neely's results and the results we observed in our control group that raise questions about some of the conclusions presented in the McDonald et al. (1996) and Spicer et al. (1994) papers. Even when considering the important differences between Neely's (1977) results and those in our control groups, we argue that our results support the conclusions of normal automatic semantic activation and deficient set-shifting in Parkinson's disease. We also introduce the notion of generalized priming to account for some of the priming effects observed in our studies.
在两项已发表的研究中，我们采用了尼利（1977年）词汇判断范式的一个变体，来研究帕金森病非痴呆患者的注意力转移和自动词汇激活（麦克唐纳、布朗和戈雷尔，1996年；斯派塞、布朗和戈雷尔，1994年）。阿诺特和切纳里（即将发表）注意到尼利的研究结果与我们在对照组中观察到的结果之间存在差异，这对麦克唐纳等人（1996年）和斯派塞等人（1994年）论文中提出的一些结论提出了质疑。即使考虑到尼利（1977年）的研究结果与我们对照组结果之间的重要差异，我们认为我们的结果支持帕金森病中正常自动语义激活和集合转换缺陷的结论。我们还引入了广义启动的概念，以解释我们研究中观察到的一些启动效应。
