Source cuing is a source-monitoring process in which the retrieval of a mem
ory trace is aided by the use of a memory probe that includes information t
hat is indicative of the original source. This is in contrast to source dis
crimination, where people need to retrieve the identity of the source of in
formation. Thus, in source cuing, the source information is given, and in s
ource discrimination, the source information is to be retrieved. The operat
ion of source cuing was demonstrated in two experiments in which people had
to identify which of two melodies had been heard earlier. Source cuing was
present for information that was more indicative of the source (i.e., timb
re), but not for information that was less indicative of the source (i.e.,
pitch). A third experiment demonstrated that the use of source cuing can be
influenced by the retrieval context.
