当代口语生成模型假设概念特征共享决定了在类别相关的上下文中命名对象的速度。然而，概念表示的统计模型也确定了特征独特性的作用，即识别单个概念并用于快速将其与其他类似概念区分开来的特征。在三个实验中，我们研究了独特的特征是否可以解释图画词干扰（PWI）范式中反直觉语义促进效应的报告。在实验 1 中，分类相关的干扰项在语义相似性评级方面进行匹配（例如，斑马和小马），并在特征独特性方面进行操作（例如，斑马与其他马科动物不同，有条纹），引发了相当程度的干扰效应。实验 2 和 3 研究了特征独特性对于具有部分-整体干扰-目标关系的促进命名的报告的作用（例如，驼峰是 CAMEL 的一个区别部分，而膝盖则不是，而与插头等不相关的部分相比）。当相关干扰项表示的部分在目标图片中不可见时（无论是否独特；实验2），相关部分干扰项不会显着影响目标图片命名延迟。当相关干扰项表示的部分在目标图片中可见时，非独特部分干扰项会在 SOA 为 -150 毫秒时显着减慢目标命名速度（实验 3）。因此，我们的结果表明，PWI 中的部分-整体干扰项-目标关系确实会发生语义干扰，但前提是干扰项表示与目标和其他类别样本共享的特征。我们讨论了这些结果对一些最近开发的口语词汇生成中词汇访问的新颖描述的影响。
Contemporary models of spoken word production assume conceptual feature sharing determines the speed with which objects are named in categorically-related contexts. However, statistical models of concept representation have also identified a role for feature distinctiveness, i.e., features that identify a single concept and serve to distinguish it quickly from other similar concepts. In three experiments we investigated whether distinctive features might explain reports of counter-intuitive semantic facilitation effects in the picture word interference (PWI) paradigm. In Experiment 1, categorically-related distractors matched in terms of semantic similarity ratings (e.g., zebra and pony) and manipulated with respect to feature distinctiveness (e.g., a zebra has stripes unlike other equine species) elicited interference effects of comparable magnitude. Experiments 2 and 3 investigated the role of feature distinctiveness with respect to reports of facilitated naming with part-whole distractor-target relations (e.g., a hump is a distinguishing part of a CAMEL, whereas knee is not, vs. an unrelated part such as plug). Related part distractors did not influence target picture naming latencies significantly when the part denoted by the related distractor was not visible in the target picture (whether distinctive or not; Experiment 2). When the part denoted by the related distractor was visible in the target picture, non-distinctive part distractors slowed target naming significantly at SOA of −150 ms (Experiment 3). Thus, our results show that semantic interference does occur for part-whole distractor-target relations in PWI, but only when distractors denote features shared with the target and other category exemplars. We discuss the implications of these results for some recently developed, novel accounts of lexical access in spoken word production.
