The current study examines the relation between cognitive control and linguistic competition resolution at the sublexical level in bilinguals. Twenty-one Spanish-English bilinguals and 23 English monolinguals completed a non-linguistic Stroop task (indexing inhibitory control) and a linguistic priming/lexical decision task (indexing Spanish phonotactic constraint competition during English comprehension). More efficient Stroop performance (i.e., a smaller Stroop effect) in bilinguals was associated with decreased competition from Spanish phonotactic constraints during English comprehension. This relation was observed when nonword targets overlapped in phonotactic constraints and phonological form with preceding primes (e.g., prime: target: ). Findings suggest a link between non-linguistic cognitive control and co-activation of linguistic structures at the sublexical level in bilinguals.
当前的研究考察了双语者在次词汇层面上认知控制与语言竞争解决之间的关系。21名西班牙-英语双语者和23名英语单语者完成了一项非语言的斯特鲁普任务（用于衡量抑制控制）以及一项语言启动/词汇判定任务（用于衡量英语理解过程中西班牙语音位结构限制的竞争）。双语者更高效的斯特鲁普任务表现（即，较小的斯特鲁普效应）与英语理解过程中西班牙语音位结构限制的竞争减少有关。当非词目标在音位结构和语音形式上与前面的启动词重叠时（例如，启动词：目标：），这种关系就会被观察到。研究结果表明，双语者在非语言认知控制与次词汇层面语言结构的共同激活之间存在联系。
