A cross-modal lexical decision task was used to explore the effects of lexical competition and dialect exposure on phonological form priming. Relative to unrelated auditory primes, matching real word primes facilitated lexical decision for visual real word targets, whereas competing minimal pair primes inhibited lexical decision. These effects were robust across two English vowel pairs (mid-front and low-front) and for two listener groups (mono-dialectal and multi-dialectal). However, both the most robust facilitation and the most robust inhibition were observed for the mid-front vowel words with few phonological competitors for the mono-dialectal listener group. The mid-front vowel targets were acoustically more distinct than the low-front vowel targets, suggesting that acoustic-phonetic similarity leads to stronger lexical competition and less robust facilitation and inhibition. The multi-dialectal listeners had more prior exposure to multiple different dialects than the mono-dialectal group, suggesting that long-term exposure to linguistic variability contributes to a more flexible processing strategy in which lexical competition extends over a longer period of time, leading to less robust facilitation and inhibition.
一项跨模态词汇判断任务被用于探究词汇竞争和方言接触对语音形式启动的影响。相对于不相关的听觉启动刺激，匹配的真实单词启动刺激促进了对视觉真实单词目标的词汇判断，而竞争性的最小对立体启动刺激则抑制了词汇判断。这些效应在两组英语元音对（中前元音和低前元音）以及两组听众（单一方言听众和多方言听众）中都很显著。然而，对于单一方言听众组中语音竞争者较少的中前元音单词，观察到了最强的促进作用和最强的抑制作用。中前元音目标在声学上比低前元音目标更具区别性，这表明声学语音相似性会导致更强的词汇竞争以及更弱的促进作用和抑制作用。与单一方言听众组相比，多方言听众对多种不同方言有更多的先前接触，这表明长期接触语言变异性有助于形成一种更灵活的加工策略，在这种策略中，词汇竞争会持续更长时间，从而导致更弱的促进作用和抑制作用。
