Serial Position Effect
In immediate free recall of an ordered list, early and late items are often recalled better than middle items, but the curve changes with rehearsal, delay, distraction, modality and the memory test.

A Recency-Based Account of the Primacy Effect in Free Recall
Research-assisted source review
- What it supports
- Early items’ greater and more recent rehearsal accounted for important primacy patterns across the tested conditions, challenging a simple first-item storage story.
- Where it may not transfer
- The account applies to controlled free recall and depends on the rehearsal procedure and model assumptions. It does not show that early interface content is understood or preferred.
