The aim of this study was to compare linguistic and narrative skills of monolingual and bilingual preschoolers and to estimate linguistic predictors of the macro-structural level of narratives. A battery of linguistic measures in Italian was administered to sixty-four Monolinguals and sixty-four Early Bilinguals; it included Vocabulary, Phonological Awareness, Morphosyntactic Comprehension, Phonological Memory, Letter Knowledge, and Story Sequencing tasks. The narratives produced in the Story Sequencing task were coded. Bilinguals underachieved, compared to monolinguals, in vocabulary, phonological awareness and morphosyntactic comprehension; they also differed in Type and Token indexes and in free morphology, but not in the level of macro-structural complexity. Macro-structural parameters were predicted by Mean Length of Utterances in monolinguals, but not in bilinguals. Bilingual children are able to structure stories in their L2 with monolingual-like cohesive complexity, although 'in few words', that is, with weak L2 linguistic skills.
本研究的目的是比较单语和双语学龄前儿童的语言及叙事技巧,并评估叙事宏观结构层面的语言预测因素。对64名单语儿童和64名早期双语儿童进行了一系列意大利语语言测试,包括词汇、语音意识、形态句法理解、语音记忆、字母知识和故事排序任务。对故事排序任务中生成的叙事进行编码。与单语儿童相比,双语儿童在词汇、语音意识和形态句法理解方面表现较差;他们在类型和词元指标以及自由形态方面也存在差异,但在宏观结构复杂性水平上没有差异。单语儿童的话语平均长度可预测宏观结构参数,而双语儿童则不然。双语儿童能够用与单语儿童相似的衔接复杂性来构建其二语故事,尽管“用词较少”,即二语语言技能较弱。
