Abstract
Memory intrusions, a type of involuntary memory, are experienced by people on a daily basis yet are an under-researched phenomenon in psychology. This study examined how to better describe, manipulate, and predict memory intrusions. Participants (n=47) were tested using the stressful film paradigm to elicit memory intrusions, which were recorded over the following week. Three individual difference measures, working memory, physiological arousal, and anxiety sensitivity, were utilized for comparative analysis. The study was unable to manipulate memory intrusions with visuospatial or eye movement task conditions. Memory intrusion incidence was found to be correlated with anxiety sensitivity cognitive concerns and peaks in heart rate while no correlation with working memory was found. These results add to the current knowledge about memory intrusions phenomenology and correlates. Results also emphasize the need for future research on manipulating memory intrusions and curvilinear relationships between memory intrusion occurrence and both anxiety sensitivity and physiological arousal.
