在动词/名词生成实验中，参与者必须产生一个与刺激（通常是名词）相关的词，并属于给定的句法类别（“动词”或“名词”）。动词生成任务中的关联时表现的解释是片面的和有争议的，不同的建议强调要么联想强度或任务相关的反应之间的竞争。本文提出了一个新的解释RT性能的名词和动词生成，它依赖于联想检索和执行控制之间的功能相互作用，并明确考虑到任务无关的反应的干扰。我们假设，在这个生成任务的基本控制过程是注意的策略分配检索线索和检索后的反应检查和反应抑制。基于这一解释的分析模型准确地再现了在三个人群（年轻人，老年人，帕金森病患者）中观察到的主要经验趋势。名词和动词生成性能的解释，它的局限性，更一般的影响，其他生成任务和计算理论检索的建议的贡献进行了讨论。(C)2010 Elsevier B.

In verb/noun generation experiments, participants have to produce a word associated with a stimulus (usually a noun) and belonging to a given syntactic category ("verb" or "noun"). The explanation of RT performance in the verb generation task is partial and debated, with different proposals emphasizing either associative strength or competition among task-relevant responses. This paper presents a novel account of RT performance in noun and verb generation, which relies on the functional interaction between associative retrieval and executive control and takes explicitly into account the interference from task-irrelevant responses. We hypothesize that fundamental control processes in this generation task are the strategic allocation of attention on retrieval cues and post-retrieval response checking and response inhibition. An analytic model based on this account accurately reproduced the major empirical trends observed in three populations (young adults, older adults, Parkinson's disease patients). The contribution of the proposal for the explanation of noun and verb generation performance, its limitations, and more general implications for other generation tasks and computational theories of retrieval are discussed.
