Final answer:
The Sapir-Whorf hypothesis suggests that language shapes thought. Edward Sapir and Benjamin Whorf examined this relationship and proposed that the language one speaks influences how they think about reality.
Step-by-step explanation:
The Sapir-Whorf hypothesis, also known as linguistic relativity, suggests that the particular language one speaks influences how they think about reality. Edward Sapir and Benjamin Whorf studied this phenomenon and proposed that language shapes thought. For example, they observed how different languages have different words or expressions that can influence thought and behavior. While the hypothesis has been criticized, the relationship between language and thought continues to be a topic of study and debate among psychologists.
