This work focuses on the underlying conceptual structure of children’s category of living things from a cross-cultural, cross-linguistic perspective. School-aged children from three Argentinean communities were asked to generate the names of living things. Analyses were focused on the typicality, semantic organization, and hierarchical level of the names mentioned. We identified convergences among the names generated by children in all three communities, as well as key differences: the typicality, habitats and hierarchical level of the categories mentioned varied as a function (...) of children’s language and their direct experience with the natural world. These findings provide evidence concerning the role of language, culture and experience in shaping children’s folkbiological concepts. (shrink)
