### Pattern of Recall during the First and Second Epoch  
Overall, the analyses show a pattern of age-related increase in the remembering of memories. During the second epoch, the frequency of memory generally increases with a notable presence of complete episodic events, particularly around 5 years of age. These data confirm what is widely known about infantile amnesia. The regression analyses (see Tables 1 and 2) consider the remembering based on different types of memory and show that the presence of incomplete or semantic memories (PVF, GSM, EpF, REp is inversely related to the memory of single episodic events (SEpE)). In other words, the participants reported elements of Perceptual-Visual Fragments, General Semantic Memories, Episodic Fragments, and Repeated Events (daily routines) when a well-organized episodic memory still did not emerge. The co-occurrence of SEPE with other types of memory remains low for all types of memories considered. This result suggests that when the episodic system begins to assume a role of organizer of the experience, it becomes the most relevant form of memory and superimposes itself on less structured forms of remembering. It should be noted that the participants were explicitly asked to report events from their childhood. The reports obtained show that they recalled any memory, even when it consisted only of perceptual fragments without a well-defined narrative or general semantic memories. This phenomenon is also quite frequent and widely discussed in autobiographical memory studies [73; 74]. When a specific event is not (or poorly) remembered, it is somehow reconstructed by appealing to semantic aspects of our memory. In the remembering process the memory systems work in an integrated way, making the best use of the information available from different systems in terms of their developmental maturation. The presence of semantic memories and memories linked to daily routines confirms the important role played by the semantic system in the genesis of autobiographical memory. [PERSON] [33] has already observed the role that general or repeated events play in the recovery of one's past. The events of daily life, despite their apparent irrelevance, consti \begin{table}

Memories of trivial events are generally re-elaborated and grouped into general categories (i.e., semantized). Only the relevant events are subsumed in self-awareness as representations of crucial or salient moments of one's life. A particularly interesting aspect to discuss is the presence of memories with a prevalent perceptual component (Perceptual Visual Fragment, PVF). This component probably fosters the construction of a mental image and could play a fundamental role in giving strength to the first forms of subjective experience and their remembering. We know that the Perceptual Representation System (PRS) develops before declarative memory from an ontogenetic point of view and, therefore, precedes the maturation of semantic and episodic systems [77; 78]. PRS could be considered a sort of long-term visuospatial sketchpad, like a type of proto-memory from which the first representations, which later will become part of declarative memory, are built.
