Edward Sapir and Benjamin Whorf.

Explanation:

As the exercise explains, Edward Sapir and Benjamin Whorf studied the Hopi of the southwestern United States and concluded that language not only allows us to express our thoughts but also shapes the way we think. They argumented this claims on the basis that the Hopi, at that time, had no way (be it grammatical, oral or otherwise) to refer to what we denominate "time". What they could not develop, though, was that they did not refer to time in the way that we do. If we were to say "I met with her at 12:00 in the morning" or "We met at noon", a Hopi individual could say "We met at the time we pray" or something of the sort. Therefore, they did refer to time, but in a different fashion. However, Sapir and Whorf made the deduction that language not only allows us to express our thoughts but also shapes the way we think because they thought that as the Hopi could not name time, they did not understood it as a concept.
