Brain development in adolescence is on a higher level than that of childhood. Children are only able to think logically about the concrete — the here and now. Adolescents move beyond these limits and can think in terms of what might be true, rather than just what they see as true. They can deal with abstractions, test hypotheses and see infinite possibilities. Yet adolescents still often display egocentric behaviors and attitudes. During cognitive development in adolescence, large numbers of neurons grow rapidly. Your child’s body experiences an increase in the way these bundles of nerves connect. This allows for more complex, sophisticated thinking.
