Given the intellectual changes that occur during the adolescent stage of development,it is perhaps important to note that formal operational thinking is thinking in the abstract.Therefore,as adolescents become capable of formal operational thinking,their cognitive abilities as well as their views about the external world change.In addition,adolescents are capable of not only asking,but also of coming up with some answers to such abstract questions as "Who am ".As we have already discussed,and as we shall detail throughout the text,this is an extremely important issue in adolescent development.Hence,it appears that Piaget's notions about cognitive development,which are based on a biological predisposition interacting with cultural demands,relate to certain aspects of adolescent behavior.
