When recalled it can be accessed independently of content and is recollectively experienced. Autobiographical memory, in contrast, retains knowledge over retention intervals measured in weeks, months, years, decades and across the life span. Autobiographical knowledge represents the experienced self, or the `me`, is always accessed by its content and, when accessed, does not necessarily give rise to recollective experience.
