“…Research directly investigating conditional dependence between multiple context details suggests that young adults are more likely to bind multiple context features in memory, compared to older adults (Boywitt et al, 2012; Peterson & Naveh-Benjamin, 2016). In the current study, we found the opposite: older adults conditionally bound context details while younger adults did not.…”

“…This reduction in selective attention is suggestive of reduced inhibitory control (Hasher & Zacks, 1988). A reduced ability to selectively attend to a specific relationship may lead older adults to hyper-bind (Campbell, Hasher, & Thomas, 2010) and show a conditional dependence (Boywitt, Kuhlmann, & Meiser, 2012; Meiser, Sattler, & Weisser, 2008; Peterson & Naveh-Benjamin, 2016; Starns & Hicks, 2008) between relevant and irrelevant features during memory retrieval. A consequence of hyper-binding, in typical memory tasks, may be an impoverished memory representation for relevant contextual features.…”

Recent evidence suggests that directing attention toward single item-context associations during encoding improves young and older adults’ context memory performance and reduces demands on executive functions during retrieval. In everyday situations, there are many event features competing for our attention, and our ability to successfully recover those details may depend on our ability to ignore others. Failures of selective attention may contribute to older adults’ context memory impairments. In the current electroencephalogram (EEG) study, we assessed the effects of age on processes supporting successful context memory retrieval of selectively attended features as indexed by neural oscillations. During encoding, young and older adults were directed to attend to a picture of an object and its relationship to one of two concurrently presented contextual details: a color or scene. At retrieval, we tested their memory for the object, its attended and unattended context features, and their confidence for both the attended and unattended features. Both groups showed greater memory for attended than unattended contextual features. However, older adults showed evidence of hyper-binding between attended and unattended context features while the young adults did not. EEG results in the theta band suggest that young and older adults recollect similar amounts of information but brain-behavior correlations suggest that this information was supportive of contextual memory performance, particularly for young adults. By contrast, sustained beta desynchronization, indicative of sensory reactivation and episodic reconstruction, was correlated with contextual memory performance for older adults only. We conclude that older adults’ inhibition deficits during encoding reduced the selectivity of their contextual memories, which led to reliance on executive functions like episodic reconstruction to support successful memory retrieval.

“…That is, the age-related difference in classification accuracy in parietal cortex during the See phase may reflect the well-established age-related deficit in representing or binding feature combinations (Boywitt, Kuhlmann, & Meiser, 2012; Chalfonte & Johnson, 1996; Li, Naveh-Benjamin, & Lindenberger, 2005; Mitchell et al, 2000; Naveh-Benjamin, 2000). The relatively weaker Think-phase category representations in temporal and occipital regions for older adults may then reflect this binding deficit—that is, because of a parietal-related binding deficit, features represented in temporal cortex are less likely to cue features represented in occipital cortex and/or vice versa.…”

“…According to the source monitoring framework (SMF, Johnson, Hashtroudi & Lindsay, 1993; Mitchell & Johnson, 2009), these less accurate memories are thought to arise from poor feature encoding and/or poor binding of features into cohesive representations of specific events (Boywitt, Kuhlmann, & Meiser, 2012; Chalfonte & Johnson, 1996; Li, Naveh-Benjamin, & Lindenberger, 2005; Mitchell, Johnson, Raye, Mather, & D’Esposito, 2000; Naveh-Benjamin, 2000) and from difficulty monitoring (reviving, evaluating) during remembering (Gallo, 2013; Mitchell et al, 2000, Experiment 2).…”

Although older adults often show reduced episodic memory accuracy, their ratings of the subjective vividness of their memories often equal or even exceed those of young adults. Such findings suggest that young and older adults may differentially access and/or weight different kinds of information in making vividness judgments. We examined this idea using multivoxel pattern classification of fMRI data to measure category representations while participants saw and remembered pictures of objects and scenes. Consistent with our hypothesis, there were age-related differences in how category representations related to the subjective sense of vividness. During remembering, older adults’ vividness ratings were more related, relative to young adults’, to category representations in prefrontal cortex. In contrast, young adults’ vividness ratings were more related, relative to older adults, to category representations in parietal cortex. In addition, category representations were more correlated among posterior regions in young than older adults, whereas correlations between PFC and posterior regions did not differ between the two groups. Together, these results are consistent with the idea that young and older adults differentially weight different types of information in assessing subjective vividness of their memories.

“…Rather than being related to retrieving the conjoint features, the subjective experience of remembering in the patients seemed to be related recognition confidence. Hence, the parietal patients did not seem to be engaging in appropriate monitoring of the multidimensional representations they seemed able to retrieve-a kind of objective/subjective source memory dissociation (see Boywitt, Kuhlmann, & Meiser, 2012 for behavioral evidence of a similar dissociation in older adults). Together with other data in the literature, this seems to suggest that posterior parietal cortex is somehow involved in evaluating multidimensional information with respect to a subjective memorial experience or mapping the available objective information onto a subjective response.…”
