This article makes several contributions to research on fundamental spatial and temporal concepts: First, we set out to render the notion of fundamental concepts of space and time more precise. Second, we introduce an efficient approach for collecting behavioral data combining crowdsourcing technology, efficient experimental software tools, and an effective and comprehensive analysis methodology. Third, we present behavioral studies that allow for identifying and calibrating potential candidates of fundamental spatial concepts from a cognitive perspective. Fourth, one prominent topic in the area of spatio-temporal cognition is the influence of language on how humans conceptualize their dynamic spatial environments. We used the aforementioned framework to collect data not only from English speaking participants but also from native Chinese and Korean speakers. Our application domain are the modes of overlap proposed by Galton . We are able to show that the originally proposed spatial relations of the region connection calculus and intersection models are capturing cognitively fundamental distinctions that humans make with respect to modes of overlap. While finer distinctions are formally possible, they should not be considered fundamental conceptualizations in either Chinese, Korean, or English. The results show that our framework allows for efficiently answering questions about fundamental concepts of space, time, and space-time essential for theories of spatial information.
