Visuospatial perspective-taking in social-emotional development: enhancing young children's mind and emotion understanding via block building training.

In terms of theoretical implications, the potential causal relationship between visuospatial perspective-taking and ToM and emotion understanding may shed new insights on what underlies the development of mental state understanding. The findings of this study also have practical implications: researchers and educators may popularize visuospatial perspective-taking training in the form of block-building games if it is found to be effective in complementing conventional language-based theory-of-mind training.
