基于先前的证据表明，在对象（名词）命名的词汇选择的认知控制不同的成年人口吃（AWS）与典型流利的成年人（TFA），其目的是调查的词汇选择的认知控制行动（动词）命名在AWS。12张AWS和12张TFA命名的线条图，使用动词描述动作。一半的图片有高一致性的动作名称，另一半低一致性的动作名称。比较两组之间的视觉准确性和反应时间（RT）以及事件相关电位（ERP）与图片起始时间的锁定。低一致性试验与高一致性试验的CRTs较慢，AWS与TFA相比，这种影响的程度更大。命名RT的三角图分析显示，选择性抑制的个体差异与命名RT的AWS协议效应，但不TFA。行动命名引起额叶中央N2活动在TFA的协议条件，但不是AWS。此外，仅TFA一致性影响后期的后P3b分量。在AWS中，低一致性动作命名引起额叶P3a激活。结果表明，认知控制的行动名称的选择是定性组之间的差异。在TFA中，词汇选择的认知控制动作命名涉及非选择性抑制，以及更有效的工作记忆更新的高与低协议的试验。在AWS中，低一致性动作命名的认知控制涉及焦点注意力的增加。选择性抑制的个体差异也调节了AWS中动作命名的认知控制。
Based on previous evidence that cognitive control of lexical selection in object (noun) naming operates differently in adults who stutter (AWS) versus typically-fluent adults (TFA), the aim was to investigate cognitive control of lexical selection in action (verb) naming in AWS. 12 AWS and 12 TFA named line drawings depicting actions using verbs. Half of the pictures had high-agreement action names and the other half low-agreement action names. Naming accuracy and reaction times (RT), and event-related potentials (ERPs) time-locked to picture onset, were compared between groups. Naming RTs were slower for low- versus high-agreement trials, and the magnitude of this effect was larger in AWS versus TFA. Delta-plot analysis of naming RTs revealed that individual differences in selective inhibition were associated with the agreement effect on naming RTs in AWS but not TFA. Action naming elicited frontal-central N2 activity in both agreement conditions in TFA but not AWS. Additionally, a later, posterior P3b component was affected by agreement in TFA only. In AWS, low-agreement action naming elicited frontal P3a activation. Results suggest that cognitive control of action name selection was qualitatively different between groups. In TFA, cognitive control of lexical selection in action naming involved nonselective inhibition, as well as more efficient working memory updating on high- versus low-agreement trials. In AWS, cognitive control of low-agreement action naming involved increased focal attention. Individual differences in selective inhibition also moderated cognitive control of action naming in AWS.
