The mediating role of impulsivity in the relationship between executive functions (working memory, inhibition) and prospective memory

ABSTRACTProspective memory refers to the ability to remember and execute planned tasks. This ability is associated with certain cognitive processes and personality traits. This study investigated the mediating role of impulsivity facets in the relationship between executive functions and prospective memory. Urmia University students (n = 201) participated in this cross-sectional study conducted from October to December 2023. Cluster sampling was employed for recruitment. Data were collected using the Prospective and Retrospective Memory Questionnaire (PRMQ), Adult Executive Functioning Inventory (ADEXI), and Short UPPS-P Impulsive Behavior Scale (S-UPPS-P). Correlational analyses and path analysis were conducted. The path analysis revealed that among impulsivity facets, just lack of perseverance partially mediates the relationship between working memory and prospective memory (β = .062, p < .05), but not between inhibition and prospective memory (β = .010). These findings suggest that working memory deficits contribute to prospective memory failures, with lack of perseverance acting as a single mediator. This highlights the importance of considering both lack of perseverance and working memory for a comprehensive understanding of prospective memory difficulties.
