The theory of reconstructive memory (Bartlett): schemas, the active reconstruction of memory, and how this leads to distortion of recall.

What this dot point is asking

Edexcel wants you to describe the theory of reconstructive memory, associated with Bartlett: the idea that memory is actively rebuilt rather than replayed, that we use schemas to fill gaps, and that this leads to distortion of recall. The Bartlett (1932) core study tests this, and the theory explains why eyewitness memory is often unreliable.

Memory as active reconstruction

Bartlett rejected the idea that memory is like a video recording that plays back perfectly. Instead, he argued that when we recall something, our brain reconstructs it from stored fragments, and this reconstruction is shaped by what we already know and expect. Because the rebuild happens every time we remember, memories can change over time, drifting towards what seems to make sense.

The role of schemas

This is why two witnesses to the same event can recall it differently: each reconstructs it through their own schemas. It also explains why memory tends to become more conventional over time, losing odd details and gaining expected ones.

Why it matters: eyewitness testimony

Reconstructive memory has a major real-world use: it warns that eyewitness testimony can be unreliable. A witness may unintentionally "remember" what their schema expects (a weapon, a stereotypical offender) rather than what happened, and leading questions can push the reconstruction further from the truth. Courts therefore treat eyewitness memory with caution.

Evaluating the theory

Strengths. The theory has strong research support (Bartlett's own War of the Ghosts study and later work on eyewitness distortion) and important real-world applications to how police and courts treat witness evidence. Weaknesses. Bartlett's early methods were not tightly controlled (instructions were vague and recall was scored subjectively), and not all memory is distorted, since we recall important or distinctive events fairly accurately, so the theory may overstate how unreliable memory is.

• Cue. It warns that eyewitness testimony can be unreliable because witnesses reconstruct events through their schemas.
