Adolescent intellectual development

The physical changes of adolescence will interfere with intellectual activity to some extent. From time to time both boys and girls feel tired, apathetic and listless. At other times they are intellectually very much alive and creative, but mental output is likely to come by fits and starts. Examination strain may in some cases cause serious breakdowns and anxiety conditions.


Perceptual and manual skill are less indicative of intelligence now, and the young person uses his head more than his hands for thinking. Linguistic ability is closely correlated with mental ability in this period, and tests of the verbal type are more reliable than performance tests in estimating intelligence at this time.


The span of attention and logical reasoning continues to improve, at least up to 15 or 16 in the average individual. Learning is also more rapid. An attempt is made to generalize from the start, and errors, therefore, are eliminated more rapidly. There is also greater transference of learning owing to the greater ability to generalize. Experience in studying one type of subject matter may be more readily applied to another and so speed up the learning process. Adolescence is the period when individual differences are the most marked. Special abilities—practical, musical, mathematical, verbal, artistic and scientific—begin to appear, though there may have been some evidence of their existence before this. It is, therefore, important to provide a really wide curriculum with alternative subjects at school, and a wide range of hobbies. Given opportunity, the adolescent will usually develop his own bent at this period, and at the same time will find valuable sublimatory outlets which will counteract some of the underlying feelings of stress and strain that he is experiencing. Recently, following the passing of the Education Act of 1944, much attention has been paid to the development of secondary education and to the importance of selecting the most appropriate type of education suited to the age, ability and aptitude of the child of 11+ years. In general, it is not possible to determine with any degree of accuracy whether a child will benefit most from a more academic or a more technical type of education at so young an age. In the majority of children, special abilities tend to develop later, and psychologists consider that although the child's fitness for the Grammar School type of education may be determined on the grounds of high intelligence alone, it is unwise to make too clear cut a distinction between a practical and an academic curriculum at least until the child reaches the age of 13 years.


Interests are varied. From one investigation Schonell found that interest in woodwork and club activities tended to increase with boys during adolescence, and interest in meccano, painting and drawing, for instance, tended to decrease. Girls showed a greater interest in knitting and sewing and club activities, while interest in " collecting " and " housework " tended to diminish. Well-run social clubs are very necessary at this age. They should provide a variety of activities—dramatic, athletic, creative and social—with a leader who understands young people. This does much to correct the natural delinquent tendency of this period, or the tendency to be aloof, unsociable, dreamy and moody, which is common at this time.
