Age differences in prospective memory (PM)—memory for delayed intentions—have shown paradoxical patterns between laboratory and naturalistic settings. Virtual reality (VR) has been used to try and enhance the ecological validity of PM assessments, but methodological differences and limited validation have undermined interpretation of previous findings. We compared age differences between VR- and naturalistic-based measures of PM performance for younger (18-30 years) and older (56-83 years) adults (N = 111) to explore the role of task context and familiarity. Participants completed PM tasks embedded in the Job Simulator VR videogame and a Breakfast task that involved setting a table and simulating breakfast food preparation. We also included two real-world measures in which participants tried to remember to exchange personal belongings with the experimenter (Belongings task) and return phone calls at specific times outside the lab (Call-back task). We found comparable age deficits in Job Simulator and the Breakfast task. However, the age-PM paradox persisted in the Belongings and Call-back tasks. Hierarchical regression modeling was conducted to determine the roles of working memory, vigilance, and personality traits in each. Regression analyses revealed that significant variance in lab-based PM performance was accounted for by individual differences in working memory and agreeableness in older adults, while variance in naturalistic PM performance was accounted for by vigilance and neuroticism in young adults. This study suggests that immersive VR gameplay helped to provide ecologically valid PM assessment and advance a theoretical account of the age-PM paradox with a systematic, task-based analysis of age and individual differences in PM. Different mediators predicted young and older adults’ PM differently across real-world and in-lab contexts (despite measuring similar, naturalistic PM in the same individuals in both VR and in real life). There are methodological, cognitive, & personality moderators, but the “paradox” appears to be a real developmental phenomenon.

Primary School Age

The present study examined age differences in time-based prospective memory (TBPM) in primary school age children and tested the role of self-initiated memory retrieval and strategic time monitoring (TM) as possible developmental mechanisms. Fifty-four children were recruited from local primary schools (27 younger children, mean age = 7.2 ± 0.55 years, and 27 older children, mean age = 9.61 ± 0.71 years). The task was a driving game scenario in which children had to drive a vehicle (ongoing task) and to remember to refuel before the vehicle runs out of gas (TBPM task, i.e., the fuel gauge served as child-appropriate time equivalent). Fuel gauge was either displayed permanently (low level of self-initiation) or could only be viewed on demand by hitting a button (high level of self-initiation). The results revealed age-dependent TBPM differences with better performance in older children. In contrast, level of self-initiated memory retrieval did not affect TBPM performance. However, strategies of TM influenced TBPM, as more frequent time checking was related to better performance. Patterns of time checking frequency differed according to children’s age and course of the game, suggesting difficulties in maintaining initial strategic TM in younger children. Taken together, the study revealed ongoing development of TBPM across primary school age. Observed age differences seemed to be associated with the ability to maintain strategic monitoring.
