In this section, we delve into the complex relationship between thought and language, exploring three main viewpoints. The first perspective suggests that language acts as a determinant of thought, as exemplified by cultural differences in vocabulary, such as unique kinship terms in Hindi versus the English term 'uncle.' This idea is aligned with the linguistic relativity hypothesis proposed by Benjamin Lee Whorf, asserting that the capabilities of thought are shaped by language structures. The second perspective, championed by Jean Piaget, posits that though thought develops independently prior to language; it ultimately becomes intertwined with verbal expression. Lastly, Lev Vygotsky suggests that thought and language evolve separately during early childhood, converging around the age of two when rational speech emerges. Understanding this dynamic interplay is crucial in cognitive psychology as it highlights not only language acquisition but also the fundamental ways in which we process and express our thoughts.
