Sub-types of nonbelieved memories reveal differential outcomes of challenges to memories

Nonbelieved memories (NBMs) highlight the independence between distinct metamemorial judgements that contribute to the experience of remembering. Initial definitions of NBMs portrayed them as involving the withdrawal of belief in occurrence despite sustained recollection. While people rate belief for their NBMs as weaker than recollection, the average difference is too small to support the idea that autobiographical belief is completely withdrawn in all cases. Furthermore, autobiographical belief and recollection ratings vary considerably across NBMs. In two studies, we reanalysed data from prior studies to examine whether NBM reports reflect a single category or multiple sub-categories using cluster analytic methods. In Study 1, we identified three sub-types of NBMs. In Study 2 we incorporated the concept of belief in accuracy, and found that two of the clusters from Study 1 split into two clusters apiece. All …
