Final answer:
It is TRUE that the grand theories of personality in the latter half of the twentieth century described universal psychological features and functions, with prominent contributions from trait theorists, humanistic psychologists, and psychoanalytic theorists like Freud.
Step-by-step explanation:
It is TRUE that the grand theories of personality that became prominent in the latter half of the twentieth century made comprehensive statements about human nature. These theories attempted to explain the core psychological features and functions of all human beings. For instance, trait theorists suggest that personality comprises various traits, which are characteristic ways individuals behave. The theories recognize dimensions of personality such as sociability, aggression, optimism, and moodiness, among others. Notable trait theorists like Gordon Allport organized traits into cardinal, central, and secondary traits. Additionally, humanistic psychologists like Abraham Maslow and Carl Rogers focused on the self-actualization potential of individuals, emphasizing free will and self-determination. Freud's psychodynamic perspective also made significant contributions to the field by introducing the concept that unconscious drives, particularly those related to sex and aggression, play a crucial role in shaping personality.
