词汇的跨情境统计学习涉及跟踪听觉词汇和物体在时间上的共现，以推断词汇-所指映射。先前的研究已经表明，学习者可以通过一组语音上非常不同的单词来推断所指对象（例如，WUG，DAX），但它仍然是未知的，学习者是否可以编码精细的语音差异在跨情境的统计学习。本研究考察了学习者对在一个辅音段上不同的最小对的跨情境统计学习（例如，BON-TON），在一个元音段上不同的最小对（例如，DEET-DIT），以及在两个或三个片段上不同的非最小对（例如，BON-DEET）。学习者对所有的配对都表现出了高于机会的能力，但对元音最小配对的表现比辅音最小配对或非最小配对差。这些研究结果表明，学习者可以编码精细的语音细节，同时跟踪词所指的同现概率，但他们认为，语音编码可能比辅音元音弱。
Cross-situational statistical learning of words involves tracking co-occurrences of auditory words and objects across time to infer word-referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross-situational statistical learning. This study examined learners' cross-situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON-TON), minimal pairs that differed on one vowel segment (e.g., DEET-DIT), and non-minimal pairs that differed on two or three segments (e.g., BON-DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non-minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word-referent co-occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.
