Other universalist researchers dedicated themselves to dispelling other aspects of linguistic relativity, often attacking Whorf's specific points and examples. For example, Malotki's monumental study of time expressions in Hopi presented many examples that challenged Whorf's "timeless" interpretation of Hopi language and culture, but seemingly failed to address linguistic relativist argument actually posed by Whorf (i.e. that the understanding of time by native Hopi speakers differed from that of speakers of European languages due to the differences in the organization and construction of their respective languages; Whorf never claimed that Hopi speakers lacked any concept of time). Malotki himself acknowledges that the conceptualizations are different, but because he ignores Whorf's use of scare quotes around the word "time" and the qualifier "what we call," takes Whorf to be arguing that the Hopi have no concept of time at all.
