Yes, the concentration techniques differ for adults and children. As the capacity of their brain, learning abilities, interests, needs and energy levels are totally different, the focusing techniques for adults and children may vary. As with each individual having this issue, focusing problems in children and concentration problems in adults should be handled by taking their different needs into account. For example, since children are in the development period, sleep has a much more important effect on their lack of focus. Likewise, since their energy is much higher, exercise has a more important role in solving focus problems in children. On the other hand, since the development has been completed, concentration issues in adults should be analyzed much better and more deeply. Focusing problems in adults can be based on much more individual reasons.
