What about simple time lapse? With images and video the larger the time lapse the faster things appear to be moving especially with blur. What if something similar held for memory?
The key memories that are remembered will typically have longer lapses for the older than for the younger. Cognitive expectations might then correct this gap by fudging a perception or sense of elapsed time, creating a quickened time lapse like effect for experiences, which strengthens as you get older.
It would be interesting to ask people with autobiographical memories how they perceive time - according to my analogy it wouldn't change since they maintain most 'frames'.
