This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of age, by specifically examining language knowledge and spontaneous language use in each language. A direct impact of the amount of linguistic exposure on the longitudinal growth of lexico-semantic and syntactic abilities was observed in both languages. While phonological skills were not directly influenced by exposure, they were more proficient in the more exposed language. The use of lexically diverse and syntactically rich utterances developed relatively later than language knowledge, both supported by the amount of linguistic exposure.
本研究考察了语言输入对三个基本语言领域（词汇语义、句法和语音）产出技能和接受技能发展的影响。研究对71名（35名女性）巴斯克语 - 西班牙语双语儿童在4至6岁之间的三个时间点（2018年秋季、2019年夏季、2021年冬季）进行了评估，具体考察了每种语言的语言知识和自发语言使用情况。研究观察到，语言接触量对两种语言的词汇语义和句法能力的纵向增长都有直接影响。虽然语音技能不受接触量的直接影响，但儿童在接触较多的语言中表现得更熟练。词汇多样和句法丰富的话语的使用比语言知识发展得相对较晚，二者都受到语言接触量的支持。
