ABSTRACT:
The age-prospective memory (ProM) paradox asserts that, despite evidence of age-associated ProM deficits on laboratory tasks, older adults perform comparably to young adults on semi-naturalistic ProM tasks. This study examined the nature and predictors of this paradox in older HIV-infected individuals, who represent a growing epidemic and demonstrate significant ProM deficits.According to the age-prospective memory (ProM) paradox, healthy older adults perform comparably to younger adults on semi-naturalistic ProM tasks despite demonstrating significant ProM deficits in the laboratory. The present study examined the nature and predictors of this discrepancy in older adults with HIV, who represent a growing epidemic due to success of antiretroviral treatment and are at increased risk for HIV-associated neurocognitive impairment. Participants included 48 older (50+ years) and 42 younger (<40 years) HIV-infected individuals, who completed the Memory for Intentions Screening Test (MIST) in addition to time-based (i.e., 24-hour telephone call) and event-based (i.e., hidden object) semi-naturalistic tasks. IAn interactions emerged between tasks and age group (ps<0.05), such that t. The older HIV+ individuals demonstrated significantly lower MIST summary scores than younger HIV+ participants (d=0.58; p<0.01), but there were no between-group differences on the MIST’seither semi-naturalistic task (24-hour call: d=0.04; hidden object: d=0.02; trial (i.e., a 24hr telephone task; ps>0.10). These effects were not better explained by other demographic, psychiatric, or disease variables. Furthermore, there was an interaction between age and self-reported ProM strategies (p<0.05), with semi-naturalistic task success being associated with greater compensatory ProM strategy use among older (d=0.77; p<0.01), but not younger (p>0.10) adults. These effects were not better explained by other demographic, psychiatric, or disease variables.Furthermore, self-reported compensatory ProM strategy use predicted time-based, but not event-based, semi-naturalistic task performance within the older HIV+ adults, whereby greater strategy use was associated with 24-hour call success but not with success on the hidden object task. These findings suggest that although older HIV-infected adults exhibit moderate ProM deficits on laboratory measures versus their younger counterparts, such these impairments are not evident on ecologically relevant ProM activities, perhaps due to effective utilization of ProM-based compensatory strategies during more cognitively demanding tasks. |
