Levinson's theory of language and thought suggests that language shapes our cognitive processes and influences how we perceive the world. According to this theory, the structure and vocabulary of a language can affect the way its speakers think about time, space, and relationships. This means that different languages may lead to different ways of understanding and interacting with reality. The theory emphasizes the connection between linguistic categories and cognitive patterns, proposing that language is not just a tool for communication but also a framework for thought. Levinson conducted cross-cultural studies to illustrate how language can guide attention and influence memory, highlighting the interplay between language and cognition.
