Using Practice Testing, Public Speaking, and Source Monitoring to Examine the Influences of Learning Strategies and Stress on Episodic Memory

Prior research demonstrated that learning information via retrieval practice, which entails studying and taking practice tests, resulted in less memory ...

Research has demonstrated that feeling-of-knowing (FOK) judgments are affected by the amount of accessible information related to an inaccessible target. Further, studies have demonstrated that, in some situations, FOK judgment magnitude is not only related to the amount (quantity) of accessed features, but also the correctness of those features (Thomas, Bulevich, & Dubois, 2011). The present study examined the conditions under which the correctness of features would influence FOK judgment magnitude. We hypothesized that accuracy of retrieved features would influence FOK judgments, but only in situations where semantically meaningful information was accessible. In three experiments, we manipulated accessibility of semantic information. In all experiments, the quantity, or amount of retrieved partial information had a greater impact on FOK judgments than the accuracy of that information. However, in situations where semantic information was accessible, accuracy of retrieved semantic features also influenced FOK judgment magnitude, and later recognition.

An analysis of the determinants of the feeling of knowing.

Studies suggest that age differences in false memories may be related to deficits in frontal lobe functioning (FLF; Butler, McDaniel, Dornburg, Price, & Roediger, 2004, Psychonomic Bulletin & Review, 11, 921). In addition, research has demonstrated that item-specific encoding can reduce false memories in younger adults ( Arndt & Reder, 2003, Journal of Experimental Psychology: Learning, Memory, and Cognition, 28, 830). In the present study we examined whether younger and older adults who perform poorly on tests designed to assess frontal function would be less likely to benefit from item-specific encoding in a false memory paradigm. In three experiments, participants studied categorized word or picture lists. Encoding manipulations were designed to emphasize either item-specific or relational processing. Younger adults and high FLF older adults showed a reduction in false memories when item-specific processing was implemented. However, low FLF older adults showed a reduction in false memories only when relational processing was impoverished. Results suggest that frontal function directly influences the engagement in distinctive encoding processes. 

The interaction between frontal functioning and encoding processes in reducing false memories.

The present research compared metamemorial monitoring processes among younger adults, nondemented older adults, and older adults diagnosed with early stage Dementia of the Alzheimer's Type (DAT).
