“…Children’s spatial word production (e.g., “left/right”, “by/next”, “middle”) predicts performance on tasks involving those spatial relations (Hermer-Vazquez et al, 2001; Miller et al, 2016; Simms & Gentner, 2008). Similarly, children who hear more spatial words from their caregivers in unstructured play (Pruden et al, 2011) or in museum-based interactions (Polinsky, Perez, Grehl, & McCrink, 2017) tend to produce more spatial words themselves, and perform better on spatial tasks. Based on these findings, theorists proposed that, as children acquire or gain experience using spatial words, they become better at using language to encode relevant spatial features, enhancing their spatial performance (e.g., Pruden et al, 2011).…”
