The memory is divided into different systems and interconnected. It allows the creation of the subject and its interaction with the environment in which they live. During the development, behavioral and biological changes are occurring, sometimes quickly and others slowly, respecting the neuronal maturation, social interaction and culture in which they live. In this aspect, some skills are innate and others, acquired, learned. In this context, emotion plays a modulator of cognitive functions, strengthening or weakening the storage of information, ie, influencing memory. It can present divided into stages (sensory, short term and long term), in steps (encoding, storage and retrieval), and types (declarative or explicit and implicit or non-declarative). The explicit type is subdivided into episodic and semantic, the implicit include the habits and skills, and the short-term memory includes the working memory. The brain areas involved are the hippocampus, frontal and temporal lobes, and amygdale. in the formation of new memories and the recognition and consolidation during learning, and amygdala, allowing storage of the episodes that involve more emotion. There are distinctions in the memory systems during the development: babies reproduce actions, recognize faces and family events and have implicit memory (which does not change much throughout development), preschool children have a more sophisticated memory by organizing the information better; and during school memory is already more developed. The study showed that semantic memory improves gradually with age, following the expansion of vocabulary; episodic memory develops in a more timely, and working memory presents late maturation, following the development of executive functions.
