Another example of her work is how she highlighted the difference in the organization of time and space from English to Mandarin. In her article “Does language shape thought? Mandarin and English speakers' conceptions of time” Boroditsky has argued for a weak version of linguistic relativity, providing a ground for it through her cross-language studies on verb tenses carried out with English and Mandarin speakers. She argues that English speakers conceive time in a way that is analogous to their conception of spatial horizontal movement, whereas native Mandarin speakers associate it with vertical movement. She has also stated that these differences do not totally determine conceptualization, since it is possible for the speakers of a language to be taught to think like the speakers of other languages do, without needing to learn any such language. Therefore, and according to Boroditsky, mother tongues may have an effect on cognition, but it is not determining.
