Episodic memory (EM) is a subsystem responsible for storing and evoking information about the "What", "Where" and "When" elements of an event in an integrated way. This capacity depends of structures with hippocampus and prefrontal cortex. The effect of aging on some capacities mediated by these areas, such as the influence of the number of objects on the coding of EM, remains unexplored. The present study examined the memory recall capacity of young and older adults in an EM task which used the number of 2, 4 and 6 items associated with specific space-temporal contexts. The young adults showed better performance coefficients than the older adults in all tasks, regardless of the load used, for all questions, except the "What" type. The group differences increase with load augmentation, stabilizing from the tasks with 4 items. In short, the EM efficiency, evaluated through What-Where-When Task, depends on the quantity information encoding. |
