Choose two theorists mentioned in chapter one of your text—How does their theory share commonalities and differences in understanding human behavior and mental processes? Do any of the scientific foundations upon which psychology was based still make sense today? Can you think of any of the contemporary approaches that may still use some of the concepts of these foundations? Can psychologists really fully understand human behavior? We say that the basis of psychological research is to understand human behavior, but is this possible considering that all human beings are separate individuals and no two people are exactly alike?
There are several theorists who developed several theories in the field of psychology. These include Bruner who developed the theory of cognitive development in children, Bowlby who developed the theory of attachment. Kuhn developed the theory of psychology and Kohlberg with his theory of moral development among others. This paper focuses on Bowlby and his theory of attachment. Bowlby suggested that a child would initially form only one primary attachment and that the attachment figure acted a secure base for exploring the world.
