Final answer:
Alfred Adler contributed to psychodynamic thought with the concept of the inferiority complex, focusing on social factors and childhood development to explain personality.
Step-by-step explanation:
Alfred Adler, who was a contemporary of Sigmund Freud and the first president of the Vienna Psychoanalytical Society, made several lasting contributions to psychodynamic thought. One of his major ideas was the concept of the inferiority complex, which refers to a person's feelings that they lack worth and don't measure up to others' standards or societal expectations. Unlike Freud, who emphasized sexual and aggressive urges, Adler proposed that feelings of inferiority in childhood drive people to strive for superiority, influencing all of our thoughts, emotions, and behaviors. Adler also placed significant importance on social connections and the role of society in shaping personality. Adler's thoughts on social aspects of development and the inferiority complex present a significant shift from Freud's emphasis on biological drives.
