Finding Where and Saying Where: Developmental Relationships between Place Learning and Language in the First Year

The relationship between emergent spatial understanding in different cognitive domains, including navigation and language, has rarely been studied using methods that allow for the examination of individual differences. In this study the authors explored emergent place learning and its relationship to early spatial language, namely prepositions, in 16- to 24-month-old children. Children were tested using a spatial task adapted from the Morris water maze, and the MacArthur Communicative Development Inventory. In the place-learning task, children were placed in a circular enclosure and a puzzle was hidden under the floor at one location. Before each trial, children were disoriented and placed in the maze at a different starting position. Their search types and success at finding the puzzle were coded. As expected, older children demonstrated more spatial searches and better place-learning skills (finding the goal), as well as greater overall expressive vocabulary. Place learning and language did not correlate with each other once age was partialled, with one crucial exception: a theoretically predicted correlation between prepositions and goal localization.
