This dissertation is a cross-cultural study of the relationship between cultural complexity and linguistic variables. The hypothesis is supported using a sample of fifty languages. Cultural complexity is theorized to instigate change in linguistic devices that are better tailored to express new areas of discourse.

This paper examines the Berlin-Kay color salience theory and offers four correlates of color salience: earliness of introduction, brevity of expression, frequency of use, and frequency of mention in ethnographic literature. All four correlations support the Berlin-Kay theory. The authors suggest that salience may be “an important general principle of cultural evolution” (1107).
