People segment ongoing experience into meaningful chunks that support new learning and long-term memory. We synthesize evidence showing that scaffolding segmentation improves memory, possibly by reducing interference. These findings highlight the role of segmentation in memory formation and suggest mechanisms for improving memory in older adults and clinical populations.
