source monitoring
Summary
Source monitoring is the process of deciding where a memory came from: who told you, where you saw it, or whether you imagined it. Its failures, called source monitoring errors or source misattribution, are a testable reason memory is reconstructive and can be distorted, as in the misinformation effect.
Detail
Meaning: Source monitoring is how people attribute a memory or belief to its origin: a particular person, place, or time, or an internal source (imagined, dreamed) versus an external one (actually experienced). The content of a memory and the context in which it was acquired are stored and retrieved as partly separate information. The content can therefore persist while the source is lost or swapped. This is one reason memory is described as reconstructive rather than a recording.
On the MCAT: Passages describe a witness who saw a face in a mugshot and later picks that person from a lineup, believing the face came from the crime scene. Others describe participants who read misleading information after an event and later report it as part of the original event (misinformation effect). Named cases include source amnesia (remembering a fact but not where it was learned), cryptomnesia (mistaking a remembered idea for your own, as in unintentional plagiarism), and confusing imagined events with real ones. Expect questions asking you to identify the error or to explain why a witness's confidence does not guarantee accuracy.
Common confusion: A source monitoring error is not forgetting the information itself. The content is remembered, but its origin is wrong. Do not confuse it with "source" in persuasion, where source characteristics means features of the messenger, such as credibility.
