Final answer:
Alfred Adler believed that the inferiority complex and the striving for superiority are central to understanding an individual's personality. Adler's theory of individual psychology emphasizes the role of social motives over Freud's sexual and aggressive ones, thereby highlighting the three fundamental social tasks as crucial in understanding a person's motivations.
Step-by-step explanation:
According to Alfred Adler, a key figure in the field of personality psychology, the most important key to understanding a person is contained in his or her striving to overcome feelings of inferiority and to achieve feelings of superiority, which he termed as the individual's inferiority complex.
In addition to this, Adler identified three fundamental social tasks (occupational tasks, societal tasks, and love tasks) that frame our life experiences and ambitions.
These tasks are pursued consciously and are central in understanding an individual's psychological motivation according to Adler's theory of individual psychology.
Unlike Freud's emphasis on unconscious motivations driven by sexual and aggressive urges, Adler focused on the social dimensions of behavior and the conscious efforts of individuals to navigate life's challenges.
