  • Maslow's hierarchy of needs sets self-actualization apart from many of the "baser" needs, like needing food or belonging.
  • However, research in evolutionary psychology suggests that self-actualization may not be so different after all.
  • Instead, it may simply be another way of attaining status, ensuring that the self-actualized individual can acquire a mate and care for offspring.
