Previous research suggests that exposure to accent variability can affect toddlers’ familiar word recognition and word comprehension. The current preregistered study addressed the gap in knowledge on early language development in infants exposed to two dialects from birth and assessed the role of dialect similarity in infants’ word recognition and comprehension. A 12-month-old Norwegian-learning infants, exposed to native Norwegian parents speaking the same or two Norwegian dialects, took part in two eye-tracking tasks, assessing familiar word form recognition and word comprehension. Their parents’ speech was assessed for similarity by native Norwegian speakers. First, in contrast to previous research, our results revealed no listening preference for words over nonwords in both monodialectal and bidialectal infants, suggesting potential language-specific differences in the onset of word recognition. Second, the results showed evidence for word comprehension in monodialectal infants, but not in bidialectal infants, suggesting that exposure to dialectal variability impacts early word acquisition. Third, perceptual similarity between parental dialects tendentially facilitated bidialectal infants’ word recognition and comprehension. Forth, the results revealed a strong correlation between the raters and parents’ assessment of similarity between dialects, indicating that parental estimations can be reliably used to assess infants’ speech variability at home. Finally, our results revealed a strong relationship between word recognition and comprehension in monodialectal infants and the absence of such a relationship in bidialectal infants, suggesting that either these two skills do not necessarily align in infants exposed to more variable input, or that the alignment might occur at a later stage.

从出生开始应对方言：变异对婴儿早期语言发展的作用。来自挪威方言的见解
先前的研究表明，接触口音变化会影响幼儿熟悉的单词识别和单词理解。目前的预注册研究解决了出生时接触两种方言的婴儿早期语言发展的知识差距，并评估了方言相似性在婴儿单词识别和理解中的作用。一名 12 个月大的学习挪威语的婴儿接触到讲相同或两种挪威方言的挪威本土父母，参与了两项眼动追踪任务，评估熟悉的单词形式识别和单词理解。他们父母的讲话由以挪威语为母语的人评估相似度。首先，与之前的研究相比，我们的研究结果表明，单方言和双语婴儿对单词的听力偏好都没有超过非单词，表明在单词识别开始时可能存在特定于语言的差异。其次，结果显示了单方言婴儿对单词理解的证据，但双语婴儿则没有，这表明接触方言差异会影响早期单词习得。第三，父母方言之间的感知相似性倾向于促进双语婴儿的单词识别和理解。第四，结果显示评分者和父母对方言之间相似性的评估之间存在很强的相关性，表明父母的估计可以可靠地用于评估婴儿在家中的语言变异性。最后，我们的结果揭示了单方言婴儿的单词识别和理解之间的密切关系，而双语婴儿则没有这种关系，
