A more complex motivation theory was proposed by Sigmund Freud. For him, a person's organization life was founded on the compulsion to work and the power of love. He saw much of human motivation as unconscious by nature. Psychoanalysis was Freud's method for delving into the unconscious mind to better understand a person's motives and needs. Freud's Psychodynamic theory offers explanations for irrational and self-destructive behavior, such as suicide or workplace violence. The motives underlying such traumatic work events may be understood by analyzing a person's unconscious needs and motives. The psychoanalytic approach also helps explain workplace deviant behavior,which can have a negative impact on business unit performance. Freud's the orizing is imiportant as the basis for subsequent need theories of motivation. Research suggests that people's deeper feelings may transcend culture, with most people caring deeply about the same few thigs.
