Bartlett's theory of reconstructive memory

Your memory is not a video recording. Bartlett argued that we rebuild our memories each time we recall them, using what we already know.

Memory is active

Bartlett (1932) said memory is an active process. We do not store exact copies: we store bits of information and reconstruct the rest when we recall.
We try to make sense of what we remember. Bartlett called this effort after meaning.

How schemas form and affect memory

How schemas are formed: a schema is a mental framework of knowledge built from experience and culture. For example, through many visits, you build a schema of what happens in a restaurant.
How schemas influence memory: when we recall, gaps are filled using schemas, so memories change to fit what we expect:
Omission: leaving out details that do not fit our schemas.
Transformation: changing unfamiliar details into familiar ones.
Rationalisation: adding reasons or explanations so the memory makes sense.
Shortening: recalling less over time.

Strengths and weaknesses

Strengths: supported by Bartlett's War of the Ghosts study, where people changed an unfamiliar story to fit their culture. It has real-life applications: it explains why eyewitness memories can be inaccurate, so courts should treat them with care.
Weaknesses: schemas are hard to observe or measure, so the theory is vague about exactly how reconstruction works. It does not explain why some memories are very accurate, and some later studies found far fewer errors when people were told to be accurate.
Worked example

Mia remembers a wedding and says the bride wore white, but photos show she wore red. Explain this using reconstructive memory.

  1. Mia's wedding schema includes brides wearing white.
  2. When recalling, she filled the gap using this schema.
  3. This is a transformation to fit her expectations.

Answer: Her schema for weddings changed the memory to fit what she expected, so she reconstructed it inaccurately.

Key idea

Bartlett said memory is active and reconstructive. Schemas formed from experience and culture fill gaps when we recall, causing omissions, transformations and rationalisations. The theory explains eyewitness errors but is vague and does not explain accurate memories.
