"None of the above" as a correct and incorrect alternative on a multiple-choice test: implications for the testing effect

Both positive and negative testing effects have been demonstrated with a variety of materials and paradigms (Roediger & Karpicke, 2006b). The present series of experiments replicate and extend the research of Roediger and Marsh (2005) with the addition of a "none-of-the-above" response option. Participants (n=32 in both experiments) read a set of passages, took an initial multiple-choice test, completed a filler task, and then completed a final cued-recall test (Experiment 1) or multiple-choice test (Experiment 2). Questions were manipulated on the initial multiple-choice test by adding a "none-of-the-above" response alternative (choice "E") that was incorrect ("E" Incorrect) or correct ("E" Correct). The results from both experiments demonstrated that the positive testing effect was negated when the "none-of-the-above" alternative was the correct response on the initial multiple-choice test, but was still present when the "none-of-the-above" alternative was an incorrect response.     

Evaluating information processing in Autism Spectrum Disorder: The case for Fuzzy Trace Theory

Literature on the developmental trajectory of cognition in Autism Spectrum Disorders (ASD) presents several inconsistent findings. In this review, we focus on information processing, and specifically, the use of gist and verbatim representations to guide memory, reasoning, and concept formation. The added perspective of Fuzzy Trace Theory may help to resolve mixed results regarding the frequency, nature, and effectiveness of gist processing in ASD by providing established process models and tasks suitable for use in individuals at all levels of functioning. In order to demonstrate the utility of FTT to the field of ASD research, we present evidence from three complementary theories–Weak Central Coherence (WCC), Executive Function (EF), and Theory of Mind (ToM)–which have dominated the landscape to date. We discuss the potential utility of FTT tasks and process models, proposing testable hypotheses that address ambiguous or conflicting results in the current literature. Applying a theory of typical development to the study of ASD may add value to past and future research.     

Memory conjunction errors for autobiographical events: More than just familiarity

Two diary studies investigated the prevalence of memory conjunction errors for real‐life events. In both studies, participants completed detailed diary pages over the course of several weeks. Participants in both diary studies committed memory conjunction errors on a later recognition memory test. In the second diary study participants also made remember/know judgements. For a large proportion of their memory conjunction errors participants indicated that they “remembered” the event occurring in that context. These diary studies demonstrate that memory conjunction errors do occur for autobiographical memories, and these errors can seem compelling.     

Attention and the acquisition of new knowledge: their effects on older adults' associative memory deficit

Older adults experience a selective associative memory deficit by demonstrating intact item memory relative to impaired associative memory when compared with younger adults. Age-related deficits in associative memory have been suggested to arise from declines in attentional resources, and the role of attention during encoding and retrieval in associative memory for words and their spatial locations was investigated in the current experiment. Additionally, the tendency of younger and older adults to use knowledge acquired during encoding to improve their associative memory judgments through a strategic associative memory process was also investigated. Younger and older adults studied a list of words with each word belonging to one of four categories, which followed one of four mathematical probability structures for their presentation. Older adults exhibited intact item memory and impaired associative memory relative to full attention younger adults. In addition, both older and younger adults demonstrated an ability to engage in strategic associative memory, by learning and later using the probability structure introduced at study to guide their associative memory judgments. In contrast, dividing the attention of younger adults during encoding impaired item memory, associative memory and strategic associative memory, whereas dividing attention at retrieval did not result in similar deficits. These data add to a growing body of literature demonstrating older adults to exhibit a selective associative memory deficit that is not simulated by dividing the attention of younger adults at encoding or retrieval. Furthermore, younger and older adults maintain the ability to use new knowledge to guide their associative judgments.     

Qualities of memories for performed and imagined actions

When people imagine performing simple actions they can sometimes become confused about whether they actually performed the actions or only imagined doing so. In the present study participants performed, imagined, and heard groups of actions. During a second session participants imagined some of the earlier actions as well as some entirely new actions. On a later memory test participants sometimes falsely indicated that they had performed actions that they had only imagined and this tendency was a positive function of number of imaginings. We also found that true and false memories differed in terms of degree of perceptual detail, associated thoughts, emotions, contextual information, and kinesthetic detail. Differences between true and false memories were smaller when the action was imagined five times but were not entirely eliminated. These findings suggest that false memories produced in this paradigm can be both compelling and yet subtly different from true memories. Copyright © 2003 John Wiley & Sons, Ltd.     

Global gist extraction in children and adults

The DRM paradigm was used to examine the role of global gist extraction in producing false memories in children and adults. First-graders, third-graders, and adults watched a videotape of a woman reading seven DRM lists, and then took a recognition memory test. Blocked (vs random) presentation and instructions to attend to the theme of lists were manipulated to enhance gist processing. In the first experiment, blocked presentation increased false recognition relative to random presentation in adults but not in first-graders or third-graders. In the second experiment, instructions to attend to list themes increased false recognition in third-graders and not in adults or first-graders. The results suggest a developmental pattern in which children become more adept at global gist extraction as they get older. These results are consistent with fuzzy trace theory's prediction of better gist processing as children grow older.
