determinism refers to the hypothesis that languages determine non-linguistic cognitive processes such as the perception of shapes. It is the hypothesis that language determines thought, with the corollary that speakers of different languages may, as result, think differently. Linguistic determinism is also known as the Whorfian hypothesis.
assertion that speakers of different languages have differing cognitive systems and that these different cognitive systems influence the ways in which people speaking the various languages think about the world.
