Memory aberrations, transliminality, and delusional ideation

This study investigated the relationships between cognitive-perceptual personality dimensions (transliminality and delusional ideation) and self-report measures of memory error (Oblivion Scale and the Prospective and Retrospective Memory Questionnaire). 100 full- and part-time psychology undergraduate students completed the measures (18 men and 82 women; M = 19.3 yr., SD = 4.4). A positive correlation was found between transliminality and reported memory aberrations (Oblivion Scale scores) and also between transliminality and Prospective and Retrospective Memory Questionnaire scores. Correlations were positive between Peters, et al. Delusions Inventory and the self-report memory measures. Transliminality and Peters, et al. Delusions Inventory scores predicted the number of memory aberrations or slips reported on the Oblivion Scale and Prospective and Retrospective Memory Questionnaire. To explore whether transliminality explained additional variance to that accounted for by the Peters, et al. Delusions Inventory, forward regression was applied and showed aspects of transliminality not accounted for by Peters, et al. Delusions Inventory did not explain additional variance within the self-report memory measures.
