Answer:
Sapir-Whorf hypothesis
Explanation:
According to the Sapir-Whorf hypothesis the language the people speak influences the world view that they have i.e., the way they perceive the world.
Linguists interpret this theory in two forms:
Strong: where the language has a strong influence on people's cognition
Weak: where the language influences decisions and thinking.
Hence, the question is referring to the Sapir-Whorf hypothesis.
