The document discusses cognitive development in adolescents. It notes that cognitive development occurs in three main areas during adolescence: 1) strengthening of advanced reasoning skills which allows examining choices and selecting preferences, 2) development of abstract thinking skills to think about unseen concepts, and 3) metacognition or introspection which is awareness of one's own thought processes and ability to make independent decisions. The document advises explaining these cognitive changes to Auntie Somuah and Titi to help them understand each other better.
