Who developed the theory of personality known as "Individual Psychology"?

Alfred Adler

The correct answer is Option (3) → Alfred Adler

Adler’s theory is known as individual psychology. His basic assumption is that human behaviour is purposeful and goaldirected. Each one of us has the capacity to choose and create. Our personal goals are the sources of our motivation. The goals that provide us with security and help us in overcoming the feelings of inadequacy are important in our personality development. In Adler’s view, every individual suffers from the feelings of inadequacy and guilt, i.e. inferiority complex, which arise from childhood. Overcoming this complex is essential for optimal personality development.
