Psychotherapy of children is aimed at achieving repetition and mastery of remembered past traumas through the analysis of symbolization, play, and direct recall. Through this is achieved resolution of early- and latency-age conflicts, during latency. This chapter will provide an in-depth presentation of an important cognitive developmental step, that is, the shift in the polarity of symbols from the evocative to the communicative mode. This is an early sign of the shift from latency to adolescence.
