ABSTRACT

We investigated whether semantic context effects in speech production and comprehension are sensitive to language dominance and whether they involve domain-general executive control. We indexed these effects using semantic blocking within the cyclical semantic paradigm (corresponding to poorer performance in semantically related contexts compared to unrelated contexts) in a study that addressed the limitations of previous research: (i) we compared semantic blocking between participants tested in their native language and those tested in a language they were clearly less proficient in (not just the less dominant language), and (ii) we examined the involvement of executive control with a non-linguistic (rather than a linguistic) index. Participants in both groups showed equal semantic blocking in production and comprehension. Executive control only predicted the magnitude of semantic blocking in speech production. These results suggest that semantic context effects are insensitive to language dominance, and that effects of executive control arise in production tasks.

摘要

我们调查了语音产生和理解中的语义上下文效应是否对语言优势敏感，以及它们是否涉及域一般执行控制。在一项解决先前研究局限性的研究中，我们使用循环语义范式中的语义阻塞（对应于语义相关上下文中与不相关上下文相比性能较差）对这些影响进行了索引：（i）我们比较了在其母语中测试的参与者之间的语义阻塞语言和那些用他们显然不太熟练的语言（不仅仅是不那么占主导地位的语言）进行测试的人，以及(ii)我们用非语言（而不是语言）指数检查了执行控制的参与。两组参与者在生产和理解方面表现出相同的语义阻塞。执行控制仅预测语音生成中语义阻塞的程度。这些结果表明语义上下文效应对语言优势不敏感，并且执行控制的影响出现在生产任务中。
