Retrieval practice has generally been shown to be an effective study strategy. The benefits of retrieval practice, however, have largely been compared to restudying, a passive and ineffective study strategy. Here, I investigated the memory and metamemory effects of practicing retrieval versus generating mnemonics, an active and effective study…

Successful episodic memory requires binding of event details across spatial and temporal gaps. The neural processes underlying mnemonic binding, however, are not fully understood. Moreover, although acute stress is known to modulate memory, if and how stress changes mnemonic integration across time and space is unknown. To elucidate these issues,…

The emergence of strategic verbal rehearsal at around 7 years of age is widely considered a major milestone in descriptions of the development of short-term memory across childhood. Likewise, rehearsal is believed by many to be a crucial factor in explaining why memory improves with age. This apparent qualitative shift in mnemonic processes has…

Strategies based memory training programs are widely used to enhance the cognitive abilities of the elderly. Participants in these training programs are usually people whose mental abilities remain intact. Occasionally, people with cognitive impairment also participate. The aim of this study was to test if memory training designed specifically for…

This study aimed to compare children's performance on two mnemonic functions that engage the lateral prefrontal cortex. Brain imaging studies in adults have shown that the mid-ventrolateral prefrontal cortex is specifically involved in active controlled retrieval, and the mid-dorsolateral prefrontal cortex is specifically involved in monitoring…

Objective: To determine whether 7- to 12-year-old boys with ADHD, relative to non-ADHD age-mates, exhibit greater difficulty learning and remembering object locations. The second purpose was to examine the functional utility of mnemonic strategies, specifically speech-to-self, used by boys with and without ADHD. Method: Boys with and without ADHD…

The foreign language vocabulary learning research literature often attributes strong mnemonic potency to the cognitive processing of meaning when learning words. Routinely cited as support for this idea are experiments by Craik and Tulving (C&T) demonstrating superior recognition and recall of studied words following semantic tasks ("deep"…

The mnemonic model of posttraumatic stress disorder (PTSD) proposed by D. C. Rubin, D. Berntsen, and M. K. Bohni presents some provocative and potentially insightful ideas about this mental disorder. D. C. Rubin et al. suggested that PTSD is caused and maintained through a "pathogenic memory" (D. C. Rubin et al., 2008, p. 985) of a negative event…

Memory plasticity, or the ability to improve one's memory performance through instruction and training, is known to decline during adulthood. However, direct comparisons among middle childhood, adulthood, and old age are lacking. The authors examined memory plasticity in an age-comparative multisession training study. One hundred and eight…

Seven-, ten- and seventeen-year-olds (N=72) in control and experimental conditions were used to test the role of metamemory and metamemory activation in the development of mnemonic performance. Metamemory was found to be a necessary condition for mnemonic performance. Developmental differences were found. (Author/DB)

In 1987, Hideaki Tomoyori, a Japanese memorist, set a world record for reciting the first 40,000 digits of pi. The authors report results from a series of tests that give a view of Tomoyori's memory performance compared with that of a control group, matched for age and educational level. He showed very good scores on tasks with digits, such as…

Two studies compared the effects of imagery-based instruction and rote learning on the long-term recall of English translations of Chinese ideographs. In no instance was there any indication that imagery-based mnemonics conferred an advantage beyond the immediate test of recall. (27 references) (Author/LB)

This study investigated the effects of organization at input and cued retrieval on the free- and cued-recall memory performance of children (all male and between the ages of 8 and 12) with and without attention deficit/hyperactivity disorder (ADHD). Children with ADHD (N=20) recalled significantly fewer words/pictures than children without ADHD…

Two experiments compared the effectiveness of two separate mnemonic devices for learning the states and their capitals--one a complex key word system using substitute words for each syllable, the other a simple key word device interacting key words from the state and capital names in an illustration. In the first experiment, 88 fourth and fifth…

The keyword and context methods of learning new vocabulary were compared using university students as subjects. The keyword method was substantially better for recall of definitions when provided, but it was not significantly better on the free recall task. (LMO)
