在词汇判断(LD)任务中,参与者快速判断目标字母串是否是单词。当目标词(例如,CARROT)之前是类别提示(例如,VEGETABLE),参与者的反应比目标之前有语义中性提示(例如,空白)。以前,斯派塞,Brown和Gorell(1994)报道,PD患者在用Neely(1977)LD任务的变体测试时,表现出过度启动。也就是说,PD患者在中性线索和类别启动条件下的反应时比对照组表现出更大的差异。目前的研究发现,PD hyperpriming解释困难的语义信息。相反,过度激发似乎与PD患者亚组持续发作的总体趋势有关。
On a lexical decision (LD) task, participants quickly decide whether a target letter string is a word. When a target word (e.g., CARROT) is preceded by a category cue (e.g., VEGETABLE), participants respond more quickly than when the target is preceded by a semantically neutral cue (e.g., BLANK). Previously, Spicer, Brown, and Gorell (1994) reported that patients with PD, when tested with a variation of Neely's (1977) LD task, showedhyperpriming. That is, patients with PD exhibited alargerdifference in reaction time between the neutral cue and category prime conditions than did controls. The present study found little evidence that PD hyperpriming was explained by difficulties accessing semantic information. Rather, hyperpriming appeared to be related to a general tendency among a subgroup of patients with PD to perseverate.
