This article examines the input to Argentinian Spanish-learning children from low and middle socioeconomic status (SES). It aims to determine whether the vocabulary composition (nouns and verbs) of their input varies as a function of SES, the addressee and other contextual variables such as the type of activity and the pragmatic orientation of the utterances. Thirty children (mean: 14.3 months) and their families were audio-recorded for four hours and the middle two hours were analyzed using Computerized Language Analysis (CLAN). The nouns and verbs in child-directed speech (CDS) and overheard speech (OHS) were identified using the CLAN’s part of speech tagger MOR Morphosyntactic Analysis. Regression analyses showed effects of: (a) SES and addressee on the proportion of noun types and tokens; (b) the type of activity and the pragmatic orientation of the utterances on the proportion of nouns in CDS; (c) SES and type of activity on the proportion of entity and action-oriented utterances. These findings reveal that given the complexity of children’s home environments it is crucial to consider these social and contextual dimensions to account for the distribution of different lexical categories. How they are distributed in the input likely influences the developmental course of vocabulary acquisition.

阿根廷幼儿语言环境中的名词和动词：社会经济和与情境相关的差异

本文研究了来自中低社会经济地位（SES）对阿根廷西班牙语学习儿童的投入。它旨在确定其输入的词汇组成（名词和动词）是否根据SES，收件人和其他上下文变量（例如活动的类型和话语的实际取向）而变化。对30名儿童（平均14.3个月）及其家人进行了四个小时的录音，并使用计算机语言分析（CLAN）对中间的两个小时进行了分析。儿童定向语音（CDS）和窃听语音（OHS）中的名词和动词是使用CLAN的语音标记器MOR Morphosyntactic Analysis进行识别的。回归分析表明：（a）SES和收件人对名词类型和代词的比例的影响；（b）话语的活动类型和语用取向对CDS中名词比例的影响；（c）SES和活动类型关于实体和面向行动的话语的比例。这些发现表明，鉴于儿童家庭环境的复杂性，至关重要的是要考虑这些社会和上下文维度，以说明不同词汇类别的分布。它们在输入中的分布方式可能会影响词汇习得的发展过程。这些发现表明，鉴于儿童家庭环境的复杂性，至关重要的是要考虑这些社会和上下文维度，以说明不同词汇类别的分布。它们在输入中的分布方式可能会影响词汇习得的发展过程。这些发现表明，鉴于儿童家庭环境的复杂性，至关重要的是要考虑这些社会和上下文维度，以说明不同词汇类别的分布。它们在输入中的分布方式可能会影响词汇习得的发展过程。
