Relational Binding

Episodic memory binds together diverse elements of an event into a cohesive unit. This property enables the reconstruction of multidimensional experiences when triggered by a cue related to a past event via pattern completion processes. Such holistic retrieval is evident in young adults, as shown by dependency in the retrieval success for different associations from the same event (Horner & Burgess, 2013, 2014). Aspects of episodic memory capacity are vulnerable to aging processes, as shown by reduced abilities to form linkages within an event through relational binding (associative deficit hypothesis: Naveh-Benjamin, 2002). However, prior work has not examined whether this reduction affects holistic retrieval in typical aging. Here, we leveraged dependency analyses to examine whether older adults remember or forget events holistically, and whether the degree of holistic retrieval declines with old age. We found evidence for continued holistic retrieval, because accuracy for one aspect of an event predicted accuracy for other aspects of the same event. Younger and older adults did not differ in the degree of holistic recollection, despite robust age-related differences in relational binding. However, within the group of older adults, holistic recollection showed a significant decline with advancing age, controlling for pairwise relational binding performance, verbal IQ, and general cognitive status. These results suggest that a decline in holistic retrieval is an aspect of episodic memory decrements later in cognitive aging.

Capacity Limits

Prioritized encoding and retrieval of valuable information is an essential component of human memory due to capacity limits. Individual differences in value-directed encoding may derive from variability in stimulus valuation, memory encoding, or from strategic abilities related to maintenance in working memory. We collected multiple cognitive ability measures to test whether variation in episodic memory, working memory capacity, or both predict differences in value-directed remembering among a large sample of participants (n=205). Confirmatory factor analysis and structural equation modeling was used to assess the contributions of episodic and working memory to value sensitivity in value-directed remembering tasks. Episodic memory ability, but not working memory capacity, was predictive of value-directed remembering. These results suggest that cognitive processes may be differentially related to value-based memory encoding.

Abstract Patients with Parkinson’s disease have reduced reward sensitivity related to dopaminergic neuron loss, which is associated with impairments in reinforcement learning. Increasingly, however, dopamine-dependent reward signals are recognized to play an important role beyond reinforcement learning. In particular, it has been shown that reward signals mediated by dopamine help guide the prioritization of events for long-term memory consolidation. Meanwhile, studies of memory in patients with Parkinson’s disease have focused on overall memory capacity rather than what is versus what isn’t remembered, leaving open questions about the effect of dopamine replacement on the prioritization of memories by reward and the time-dependence of this effect. The current study sought to fill this gap by testing the effect of reward and dopamine on memory in patients with Parkinson’s disease. We tested the effect of dopamine modulation and reward on two forms of long-term memory: episodic memory for neutral objects and memory for stimulus-value associations. We measured both forms of memory in a single task, adapting a standard task of reinforcement learning with incidental episodic encoding events of trial-unique objects. Objects were presented on each trial at the time of feedback, which was either rewarding or not. Memory for the trial-unique images and for the stimulus-value associations, and the influence of reward on both, was tested immediately after learning and 2 days later. We measured performance in Parkinson’s disease patients tested either ON or OFF their dopaminergic medications and in healthy older control subjects. We found that dopamine was associated with a selective enhancement of memory for reward-associated images, but that it did not influence overall memory capacity. Contrary to predictions, this effect did not differ between the immediate and delayed memory tests. We also found that while dopamine had an effect on reward-modulated episodic memory, there was no effect of dopamine on memory for stimulus-value associations. Our results suggest that impaired prioritization of cognitive resource allocation may contribute to the early cognitive deficits of Parkinson’s disease.
