婴儿对过渡概率（TPs）的敏感性通过促进将高TP（HTP）单词映射到意义来支持语言发展，至少到18个月大。在这里，我们测试了这种HTP优势是否随着词汇发展的进展而保持，以及婴儿在形成单词所指映射方面是否变得更好。两组24个月大的婴儿（N= 64，均为白色，在美国接受测试）首先听包含HTP和低TP（LTP）单词的意大利语句子。然后，我们在映射任务中使用HTP和LTP单词以及违反这些统计数据的序列。婴儿学习HTP和LTP的话一样好。他们也学习了LTP违规和LTP单词，但学习HTP单词比HTP违规更好。因此，由2岁的敏感性TPs不会导致HTP的优势，而是不良的映射违反HTP的词的形式。（PsycInfo数据库记录（c）2024阿帕，保留所有权利）
Infants’ sensitivity to transitional probabilities (TPs) supports language development by facilitating mapping high-TP (HTP) words to meaning, at least up to 18 months of age. Here we tested whether this HTP advantage holds as lexical development progresses, and infants become better at forming word–referent mappings. Two groups of 24-month-olds (N= 64 and all White, tested in the United States) first listened to Italian sentences containing HTP and low-TP (LTP) words. We then used HTP and LTP words, and sequences that violated these statistics, in a mapping task. Infants learned HTP and LTP words equally well. They also learned LTP violations as well as LTP words, but learned HTP words better than HTP violations. Thus, by 2 years of age sensitivity to TPs does not lead to an HTP advantage but rather to poor mapping of violations of HTP word forms.(PsycInfo Database Record (c) 2024 APA, all rights reserved)
