- U shaped curve.
- Primacy effect: info at the beginning of a list are transferred to LTM as they receive more attention and rehearsal but is impacted if a concurrent task is introduced such as a repetition of a word

- Items in the middle decay as they are too early for STM and too late for LTM as there is little opportunity for rehearsal
