Intellectual Quotient, IQ, refers to the capacity to think logically and solve problems (Checa & Fernández-Berrocal, 2015). It is vital to note that the adolescence stage of growth is a time of very rapid cognitive development. According to Jean Piaget, adolescence is the stage of growth in which the thoughts of a person begin to take a largely abstract form, while the egocentric thinking reduces significantly (Eccles, Wigfield & Byrnes, 2003). Therefore, this development of the brain makes it possible for a person to reason in a logical and wider perspective. It is vital to note that before this stage of adolescence, a person thinks only based on the moving objects in his or her environment. Therefore, cognitive development in adolescence is characterized by the start of hypothetical thoughts based on abstract things.
For proper cognitive development during adolescence, there must advancement in the intellectual capacity of a person. The ability to have hypothetical thoughts based on abstract things only comes when one’s IQ is advanced enough to sustain and support such form of thinking. IQ is, thus, quite important in the adolescence cognitive development. IQ enables and adolescent individual to solve problems based on the abstract concepts and through utilization of hypothetical as well as deductive reasoning. IQ assists the trial and error mode of reasoning while solving problems during the adolescence cognitive development.

There are biological changes that occur in the brain structure of an adolescent. These changes in the brain structure also involve increase in the connectivity between the IQ of the individual and the high experience as well as knowledge gained from social interactions with the environment in which one lives. In essence, the IQ of an adolescent person usually connects with their increased experience and knowledge from social interactions with the world to bring about significant cognitive development.
