Relatedness needs : Needs for meaningful relationships, social acceptance, and mutual respect. Alderfer places interpersonal connection and recognition in this middle group.
Abraham Maslow : An American psychologist known for proposing a hierarchy of human needs. Maslow’s hierarchy supplied the framework Alderfer condensed and revised.
