15个月、18个月和24个月大的婴儿最先理解的空间介词是什么？它们是如何理解的？为了解决这些问题，我们使用父母问卷和优先看任务来评估介词的早期理解。给孩子们展示了在典型位置(即在桌子中央或桌子下方)或非典型位置(在桌子边缘或在桌子边缘下)描绘桌子上或桌子下的物体或动物的刺激。现有的研究和父母的评估导致了这样的预测，即儿童很早就理解了介词on和down。研究还预测，孩子们的长相行为会表现出典型性效应。结果证实，on和Under是较早被理解的空间介词之一，儿童在对这些介词的最早理解中区分了典型和非典型的on和Under情景。与宾语词一样，在15个月大的时候，他们会将空间介词最初与典型情况联系起来。到18个月时，他们将空间介词的范围扩大到包括非典型情况。
Which spatial prepositions are the first to be comprehended by 15, 18 and 24-month-olds and how are they understood? To address these questions, early comprehension of prepositions was assessed using parental questionnaires and the preferential looking task. Children were shown stimuli depicting objects or animals either on or under a table in a typical (i.e. on or under the centre of the table) or atypical position {on or under the edge of the table). Existing research and parental assessments led to the prediction that children comprehend the prepositions 'on' and 'under' very early. It was also predicted that children's looking behaviour would show typicality effects. The results corroborate that 'on' and 'under' are among those spatial prepositions that are understood early and that children differentiate between typical and atypical 'on' and 'under' situations in their earliest comprehension of these prepositions. As with object words, at 15 months they associate spatial prepositions initially with typical situations. By 18 months they broaden the scope of the spatial prepositions to include atypical situations.
