Is it all in the details? Description content and false recognition errors.

In three experiments, we examined the effect of embellished content on memory errors for thematically related items as well as whether an encoding manipulation, specifically instructions to visualize content, further affects those errors. Using a modified Deese-Roediger-McDermott (DRM) paradigm, participants listened to subsets of DRM items embedded within scene descriptions. Some descriptions embellished item connections, weaving them into cohesive scenes.

Using a Classroom-Based Deese Roediger McDermott Paradigm to Assess the Effects of Imagery on False Memories.

Associated word list procedures can elicit false memories in predictable ways by inducing associative processing, thus making it harder to monitor the accuracy of memories. The purpose of the method presented here was to induce false memories using lists of either semantically or phonologically related words and to assess the effects of imagery instructions on the recall and recognition of those false memories. To do this, we used a modified version of the Deese Roediger McDermott (DRM) paradigm.

Looking forward: the effects of photographs on the qualities of future thinking.

Future episodic thinking relies on the reconstruction of remembered experiences. Photographs provide one means of remembering, acting as a "cognitive springboard" for generating related memory qualities. We wondered whether photographs would also invite embellishment of future thought qualities, particularly in the presence (or absence) of associated memories.

False memories and the DRM paradigm: effects of imagery, list, and test type.

Several researchers have reported that instructing participants to imagine items using the Deese-Roediger-McDermott (DRM) paradigm lowers false memory rates (Foley, Wozniak, & Gillum, 2006). However, other researchers have found that imagery does not always lower false memory rates (Robin, 2010), and investigators have examined the effects of imagery manipulation on semantic but not phonological lists. In the present study, we presented 102 participants with semantic and phonological DRM lists, followed by a free recall test and final recognition test.

Working memory and executive function decline across normal aging, mild cognitive impairment, and Alzheimer's disease.

Alzheimer's disease (AD) is a progressive neurodegenerative disease marked by deficits in episodic memory, working memory (WM), and executive function. Examples of executive dysfunction in AD include poor selective and divided attention, failed inhibition of interfering stimuli, and poor manipulation skills. Although episodic deficits during disease progression have been widely studied and are the benchmark of a probable AD diagnosis, more recent research has investigated WM and executive function decline during mild cognitive impairment (MCI), also referred to as the preclinical stage of AD.
