Furthermore, cognitive linguistics pursues research on the methods of understanding while receiving information. The method of seeing the world objectively differs by society or culture because the level of different thought can be studied as linguistic difference. The research of Sapir and his disciple Whorf on language and thought is the most widely known.
Sapir-Whorf hypothesis: The structure of the mother tongue has an effect on thought independent of a language, especially the cognitive ability such as categorizing or reasoning.
The common interpretation of this hypothesis holds that a language has considerable effect on thought. But which aspects of thought does a language affect? The mechanism of perception and memory is not determined by language. For thought, the higher cognitive ability of how to perceive things seems to be the problem. When I consider which memory is stored easily or how memories connect with each other, I find the outline and distinction of a speech community.
