Who is associated with the idea that language determines thought, known as linguistic determinism?

The idea that language determines thought, known as linguistic determinism, is primarily associated with Benjamin Whorf. He argued that the structure and vocabulary of a language shape and constrain its speakers' perceptions and thoughts about the world, encapsulated in his work on the relationship between linguistic categories and the cognitive processes of individuals. Whorf's theories were influenced by observations of various languages and their unique ways of categorizing experiences. This perspective posits that the language one speaks fundamentally influences how one thinks, which aligns closely with his principle of linguistic relativity. This concept is contrasted with other theories in psychology that address cognitive development or language acquisition, which focus more on the cognitive functions of individuals rather than the structural impact of language on thought.
