Source monitoring is an aspect of memory that deals with the origin, or source, of the information. Errors in source monitoring occur when the recollected origin of a memory is attributed to an incorrect source. For example, one may recall first hearing of a concept in school when really it was first heard from the television. Errors in source monitoring have been associated with stages of development as well as cognitive and memory deficits. For a detailed review on source monitoring framework, see below:
