Some researchers have even suggested that the way our sense of space helps organize mental content can explain the puzzling phenomenon of “infantile amnesia”—the fact that we can’t recall much about our earliest years. Because very young children are not able to move through space under their own locomotion, the theory goes, they may lack a mental scaffold on which to hang their memories. Children’s impressions of their own experiences may become well enough structured to be memorable only once kids are able to move about of their own volition. As adults, our memories continue to be tagged with a sense of the physical place where the original experience occurred.
