One of the major thrusts of Eysenck's theory is that personality dimensions are not arbitrary creations of culture but rather result from the basic genetic and neurophys-iological makeup of the human species. If there were a biological basis to personality, two key assumptions should hold true. First, neurophysiological differences should exist between people high on one end of a dimension (e.g., introverts) and those high on the other end of that dimension (e.g., extraverts). Second, the basic personality dimensions should be universal and not lhnited to a given culture.
