DEVELOPMENTAL TRAINING STUDIES ARE IMPORTANT TO INCREASE OUR UNDERSTANDING OF THE POTENTIAL OF THE DEVELOPING BRAIN BY PROVIDING ANSWERS TO QUESTIONS SUCH AS: "Which functions can and which functions cannot be improved as a result of practice?," "Is there a specific period during which training has more impact?," and "Is it always advantageous to train a particular function?"In addition, neuroimaging methods provide valuable information about the underlying mechanisms that drive cognitive plasticity. In this review, we describe how neuroscientific studies of training effects inform us about the possibilities of the developing brain, pointing out that childhood is a special period during which training may have different effects. We conclude that there is much complexity in interpreting training effects in children. Depending on the type of training and the level of maturation of the individual, training may influence developmental trajectories in different ways. We propose that the immature brain structure might set limits on how much can be achieved with training, but that the immaturity can also have advantages, in terms of flexibility for learning.
