We explored the nature of infants' concepts for goal path and source path in motion events (e.g., the duck moved into the bowl/out of the bowl), specifically asking how infants' representations could support the acquisition of the semantic roles of goal path and source path in language. The results showed that 14.5-month-old infants categorized goal paths across different motion events (moving to X, moving on Y), and they also categorized source paths if the source reference objects were highly salient (relatively large in size and colorful). Infants at 10months also categorized goal paths, suggesting that the broad concept GOAL PATH precedes the acquisition of the relevant spatial terms (e.g., "to", "onto"). These results are discussed in terms of the nature of goal and source path representations in infancy (e.g., whether they are represented at a general level - one that encompasses specific relations such as containment and support) as well as the possible mechanisms that may be involved in the mapping of these representations to language.
我们探究了婴儿在运动事件中对目标路径和源路径概念的本质（例如，鸭子移入碗中/移出碗），特别询问了婴儿的表征如何支持语言中目标路径和源路径语义角色的习得。结果表明，14.5个月大的婴儿对不同运动事件中的目标路径进行了分类（移动到X，在Y上移动），并且如果源参考物体非常突出（尺寸相对较大且颜色鲜艳），他们也会对源路径进行分类。10个月大的婴儿也对目标路径进行了分类，这表明广义的目标路径概念先于相关空间术语（如“到”“在……之上”）的习得。我们从婴儿期目标和源路径表征的本质（例如，它们是否在一个通用层面上被表征——一个包含诸如包含和支撑等特定关系的层面）以及这些表征与语言映射可能涉及的潜在机制方面对这些结果进行了讨论。
