In 1985 Tulving introduced the remember-know procedure, whereby subjects are asked to distinguish between memories that involve retrieval of contextual details (remembering) and memories that do not (knowing). Several studies have been reported showing age-related declines in remember hits, which has typically been interpreted as supporting…

We investigated how the hippocampus and its adjacent mediotemporal structures contribute to contextual and noncontextual declarative memory retrieval by manipulating the amount of contextual information across two levels of the same contextual dimension in a source memory task. A first analysis identified medial temporal lobe (MTL) substructures…

Two studies are reported that explore the effect of bilingualism on memory performance. Following previous reports of a bilingual advantage in executive control that sometimes shows a greater advantage in older adults, we compared younger and older monolinguals and bilinguals on a memory paradigm that yielded separate measures of familiarity and…

It is widely assumed that older adults suffer a deficit in the psychological processes that underlie remembering of contextual or source information. This conclusion is based in large part on empirical interactions, including disordinal ones, that reveal differential effects of manipulations of memory strength on recognition in young and old…

In his analysis of the pseudoword effect, [Greene, R.L. (2004). Recognition memory for pseudowords. "Journal of Memory and Language," 50, 259-267.] suggests nonwords can feel more familiar that words in a recognition context if the orthographic features of the nonword match well with the features of the items presented at study. One possible…

This study aims to investigate two expert ecology teachers' ability to attend to essential details in a complex environment during a field excursion, as well as how they teach this ability to their students. In applying a cognitive dual-memory system model for learning, we also suggest a rationale for their behaviour. The model implies two…

Thinking about the meaning of studied words (deep processing) enhances memory on typical recognition tests, relative to focusing on perceptual features (shallow processing). One explanation for this levels-of-processing effect is that deep processing leads to the encoding of more distinctive representations (i.e., more unique semantic or…

When recognition probes seem familiar but their presentation cannot be recollected, dual-process models predict that they will be attributed to too many presentation contexts--most dramatically, to multiple contexts that are mutually contradictory. This is the phenomenon of episodic over-distribution. In the conjoint-recognition and…

We investigated whether directed forgetting as elicited by the item-cueing method results solely from "differential rehearsal" of to-be-remembered vs. to-be-forgotten words or, additionally, from "inhibitory" processes that actively impair retrieval of to-be-forgotten words. During study, participants (N = 24) were instructed to remember half of a…

Subjects performed a rapid feeling-of-knowing task developed by (Reder, L. M., & Ritter, F. (1992). "What determines initial feeling of knowing? Familiarity with question terms, not with the answer." "Journal of Experimental Psychology: Learning, Memory, and Cognition," 18, 435-451), while event-related potentials (ERPs) were recorded to identify…

Our environment contains regularities distributed in space and time that can be detected by way of statistical learning. This unsupervised learning occurs without intent or awareness, but little is known about how it relates to other types of learning, how it affects perceptual processing, and how quickly it can occur. Here we use fMRI during…

The authors of the current study examined the relationships among item-recognition, source-recognition, free recall, and other memory and cognitive ability tasks via an individual differences analysis. Two independent sources of variance contributed to item-recognition and source-recognition performance, and these two constructs related…

Three experiments examined whether the representations underlying recognition memory familiarity can be episodic in nature. Recognition without identification [Cleary, A. M., & Greene, R. L. (2000). Recognition without identification. "Journal of Experimental Psychology: Learning, Memory, and Cognition," 26, 1063-1069; Peynircioglu, Z. F. (1990).…

Three experiments examined the effects of position distinctiveness, item familiarity, and frequency of presentation on serial position functions in a task involving reconstructing the order of a subset of 12 names in a list of 20 names. Three different serial position conditions were compared in which the subset of names occurred in Positions…

How do people select among different strategies to accomplish a given task? Across disciplines, the strategy selection problem represents a major challenge. We propose a quantitative model that predicts how selection emerges through the interplay among strategies, cognitive capacities, and the environment. This interplay carves out for each…
