Other anthropologists of the "culture and personality" school also developed these ideas, notably Margaret Mead in her "Coming of Age in Samoa" (published before "Patterns of Culture") and "Sex and Temperament in Three Primitive Societies" (published just after Benedict's book came out). Benedict was a senior student of Franz Boas when Mead began to study with them, and they had extensive and reciprocal influence on each other's work. Abram Kardiner was also affected by these ideas, and in time, the concept of "modal personality" was born: the cluster of traits most commonly thought to be observed in people of any given culture.
