Short-term Memory
Limited-capacity store that holds information for seconds before it’s lost (unless rehearsed or encoded into long-term memory).
- Capacity ~7 ± 2 items (George Miller)
- Stretchable via Chunking
- Encodes by sound or surface properties; long-term memory leans on meaning
Often contrasted with Working Memory: same duration, but working memory is an active workspace, not just a holding tank.
