“…These deficits are reduced when the components of the association are already related, rather than representing a novel association (Naveh-Benjamin et al, 2003), consistent with our suggestion that associative information arises from a unitization process that transforms pairs into single items with repeated exposure. More pertinent to our results, however, is that the age-related associative deficit often manifests as an increased tendency to falsely recognize rearranged pairs rather than failure to recognize intact pairs (Old & Naveh-Benjamin, 2008;Rhodes et al, 2008;NavehBenjamin et al, 2009).…”

Memory contains information about individual events (items) and combinations of events (associations). Despite the fundamental importance of this distinction, it remains unclear exactly how these two kinds of information are stored and whether different processes are used to retrieve them. We use both model-independent qualitative properties of response dynamics and quantitative modeling of individuals to address these issues. Item and associative information are not independent and they are retrieved concurrently via interacting processes. During retrieval, matching item and associative information mutually facilitate one another to yield an amplified holistic signal. Modeling of individuals suggests that this kind of facilitation between item and associative retrieval is a ubiquitous feature of human memory.

“…Indeed, this is the view proposed by Naveh- Benjamin, Hussain, Guez and Bar-On (2003) who stated that age-related associative deficits are most apparent in the formation of completely new associations. For example, a typical associative deficit memory measure is to present pairs of unrelated words and test for memory of the words themselves and also their pairings (e.g., Naveh -Benjamin, 2000, Exp. 2).…”

Words and nonwords were used as stimuli to assess item and associative recognition memory performance in young and older adults. Participants were presented with pairs of items and then tested on both item memory (old/new items) and associative memory (intact/recombined pairs).For words, older participants performed worse than young on item and associative tests but to a greater extent on the latter. In contrast, for nonwords, older participants performed equally worse than young on item and associative tests. This is the first study to demonstrate that a manipulation of stimulus novelty can alter age-related associative deficits.

a b s t r a c tBoth the dopaminergic and glutamatergic systems modulate episodic memory consolidation. Evidence from animal studies suggests that these two neurotransmitters may interact in influencing memory performance. Given that individual differences in episodic memory are heritable, we investigated whether variations of the dopamine D2 receptor gene (rs6277, C957T) and the N-methyl-D-aspartate 3A (NR3A) gene, coding for the N-methyl-D-aspartate 3A subunit of the glutamate N-methyl-D-aspartate receptor (rs10989591, Val362Met), interactively modulate episodic memory in large samples of younger (20e31 years; n ¼ 670) and older (59e71 years; n ¼ 832) adults. We found a reliable gene-gene interaction, which was observed in older adults only: older individuals carrying genotypes associated with greater D2 and N-methyl-D-aspartate receptor efficacy showed better episodic performance. These results are in line with findings showing magnification of genetic effects on memory in old age, presumably as a consequence of reduced brain resources. Our findings underscore the need for investigating interactive effects of multiple genes to understand individual difference in episodic memory.
