We now may be nearer to reaching this goal thanks to a study associating auditory processing in children to their reading skills. The results offer a new approach for detecting the risk before the children learn to read.

However, many behaviors are heavily influenced by learning and experience. In particular, early life experiences can have a lasting impact on adult behavior. This developmental plasticity acts as a means of fine-tuning an animal’s behavior to its local...
