Misattribution of Memory
Misattribution occurs when a memory or idea is correctly recalled but incorrectly attributed to the wrong source, time, place, or person, reflecting the constructive nature of human memory.
Exhibit · the account as remembered
Daniel L. Schacter identified misattribution as one of the 'seven sins of memory' in his 1999 American Psychologist article and 2001 book. The phenomenon includes source memory confusion, false recognition, cryptomnesia (unintentional plagiarism), and deja vu. Larry Jacoby's experiments in the 1980s showed that unconscious influences of memory can produce false recognition: when participants cannot attribute familiarity to its correct source, they misattribute it to other causes such as fame or prior occurrence. Schacter's framework treats misattribution not as a flaw but as a byproduct of normally adaptive memory processes. ← reconstructed, not recorded
How the contamination enters
Misattribution arises from the constructive nature of memory. When encoding, the brain does not store a complete record of an experience but decomposes it into features stored across different brain regions. At retrieval, these features are reconstructed, and source information (where, when, how something was learned) can be lost or confused. Jacoby's process-dissociation framework shows that automatic influences of memory (fluency, familiarity) and consciously controlled recollection operate independently. When recollection fails to identify the true source of familiarity, people misattribute fluency to incorrect origins.
Competing account — Johnson's source-monitoring framework proposes that memories include various characteristics (perceptual, contextual, affective), and misattribution occurs when these source characteristics are confused. Schacter's framework emphasizes that misattribution reflects adaptive constructive processes rather than system defects. Both accounts are broadly consistent with neuroimaging evidence showing that true and false recognition share neural substrates but can be dissociated.
Seams the examination found
Subliminal matching context words increased false recognition of new words, while supraliminal matching context words decreased false recognition. This demonstrated that unconscious perception can produce illusions of memory through misattribution of fluency: when participants were unaware of the priming source, they misattributed the familiarity to having seen the word in the study phase.

Participants in the divided attention condition were more likely to incorrectly judge old nonfamous names as famous compared to new nonfamous names. Full attention participants showed the opposite pattern, correctly using their explicit memory that the names were nonfamous. This showed that without recollection to attribute familiarity to its source, participants misattributed the familiarity to fame.
Larry L. Jacoby, Victoria Woloshyn & Colleen M. Kelley · 1989 · n = 80 undergraduates (Experiment 2)
Participants frequently falsely recalled or recognized the critical lure words that were never presented. False recognition rates for critical lures often approached or exceeded correct recognition of presented words. This demonstrated how gist-based processing and associative memory can produce compelling misattributions.

Where provenance breaks
Watch for situations where you 'remember' an idea or fact but cannot recall where you learned it. Be cautious of unintentionally repeating someone else's idea as your own. In eyewitness situations, question whether your memory of an event's details comes from direct observation or from later discussion, media accounts, or suggestion.
Authenticity — robust. The core misattribution phenomena have been replicated extensively. The Jacoby-Whitehouse effect has been replicated in numerous studies with varied procedures. The DRM false recognition paradigm is one of the most replicated findings in memory research, with false recognition of critical lures demonstrated across cultures, age groups, and clinical populations. The 'becoming famous' effect has been replicated under various attention-manipulation conditions. fMRI studies have identified brain regions associated with false retrieval, generally supporting the attribution framework.

Helen Keller and cryptomnesia
Helen Keller wrote a story called 'The Frost King' that was found to closely resemble a published story she had apparently read years earlier. Keller had no conscious memory of reading the original story and was accused of plagiarism. This is a classic case of cryptomnesia, a form of misattribution where forgotten prior exposure is recalled as original ideation. Schacter (2001) discusses this case as a prime example of misattribution in his book on the seven sins of memory.

George Harrison 'My Sweet Lord' copyright case
George Harrison was sued for copyright infringement when his song 'My Sweet Lord' was found to be substantially similar to 'He's So Fine' by The Chiffons. Harrison acknowledged having heard the original song but had no conscious memory of it when composing. The court found Harrison guilty of 'subconscious plagiarism,' a legal form of cryptomnesia where prior exposure is misattributed as original composition.
To authenticate the memory
When recalling important information, explicitly consider the source: 'Where did I learn this?' and 'Could I have this from a different time, place, or person than I think?' Taking notes with source information at the time of learning can help prevent misattribution by preserving contextual cues.
Schacter (2001) recommends recording important events and milestones with contextual details. Source-monitoring training has been shown to reduce false recognition in children and older adults by encouraging attention to source-specifying features of memories.
