Background: Physical exercise is suggested to be effective for preventing cognitive decline in older adults, but the relative efficacy of different types of exercise have yet to be clarified. Objective: This single-blinded randomized controlled trial was designed to investigate the differential effects of aerobic exercise training (AT), resistance exercise training (RT), and combined exercise training (CT) on cognition in older adults with subjective memory complaints (SMC). Methods: Community-dwelling older adults with SMC (n = 415; mean age = 72.3 years old) were randomly assigned to one of the four groups: AT, RT, CT, or control group. The study consisted of two phases: a 26-week intervention and a 26-week follow-up. The participants were evaluated at baseline, 26 weeks (postintervention), and 52 weeks (follow-up). The primary outcome of this study was memory function, which was assessed using the Logical Memory II subtest of the Wechsler Memory Scale-Revised (WMS-R) score. The secondary outcomes included global cognitive function, verbal fluency, working memory, processing speed, and executive functions. Results: Intention-to-treat analysis by a mixed-effect model repeated measure showed that the AT group had significantly improved performance on the WMS-R Logical Memory II test (2.74 [1.82–3.66] points) than the control group (1.36 [0.44–2.28] points) at the postintervention assessment (p = 0.037). The effect was more pronounced in those without amnesia than those with amnesia. No significant improvement was observed in the RT and CT groups. Conclusion: This study suggests that AT intervention can improve delayed memory in community-dwelling older adults, particularly in individuals without objective memory decline.

AbstractWe analyzed verbal episodic memory learning and recall using the Logical Memory (LM) subtest of the Wechsler Memory Scale-III to determine how gender differences in AD compare to those seen in normal elderly and whether or not these differences impact assessment of AD. We administered the LM to both an AD and a Control group, each comprised of 21 men and 21 women, and found a large drop in performance from normal elders to AD. Of interest was a gender interaction whereby the women's scores dropped 1.6 times more than the men's did. Control women on average outperformed Control men on every aspect of the test, including immediate recall, delayed recall, and learning. Conversely, AD women tended to perform worse than AD men. Additionally, the LM achieved perfect diagnostic accuracy in discriminant analysis of AD versus Control women, a statistically significantly higher result than for men. The results indicate the LM is a more powerful and reliable tool in detecting AD in women than in men. (JINS, 2011, 17, 654–662)

We hypothesized that the wording and sequential order of the WMS–III Logical Memory recognition questions may bias subjects toward correct or incorrect responses on specific items. Therefore, we classified each item according to one of three potential sources of bias (yeasaying to proper names, priming of “yes” responses by previous items with similar content, naysaying to unlikely occurrences) and administered the items to 31 subjects who were completely naïve to the story content. The items predicted to have correct endorsement biases were answered correctly at greater than chance frequencies, while items predicted to be biased toward incorrect answers were missed more frequently than expected by chance. The same sources of bias were tested in an independent clinical sample of 36 neurological patients who were administered the WMS–III in the standard manner. In these patients biases appeared robust enough to be detected in the performances of clinical patients during a neuropsychological evaluation. With further research, such biases may provide avenues for detecting malingerung.

The article discusses the pedagogicalandpsychological prerequisites for intensive teaching of foreign languages. In intensive training, it is necessary to find such working methods that rely on the semantic component of logical memory, which activates the students' thinking. In this regard, intensive training involves the inclusion of the learner from the first lesson in active thought through a specially organized active learning. Favorable conditions are created for involuntary attention and memorization of the material. It is taken into account that emotionally - colored, personality-significant is remembered better, and the combination of visual-sensual and abstract-logical components of the presentation of the material contributes to the effectiveness of memorization. The entire system of introducing educational material reflects the correct specially organized alternation of imprinting and reproduction, which is carried out in controlled speech learning. The psycho-hygienic effect of intensive learning is of particular importance. Activation of the learner’s capabilities is, as it were, a compensatory psychological mechanism that counteracts the crisis.

PurposePrevious research has repeatedly shown that people only search for files in a small minority of cases when they do not remember the file's location. The current study aimed to examine whether there is a group of hyper-searchers who search significantly more than others. Based on previous neurocognitive studies, this study aims to hypothesize that if such a group exists, they will have superior verbal memory and reduced visuospatial memory.Design/methodology/approachIn total, 65 participants completed a questionnaire estimating their search percentages, as well as reporting demographic data. Verbal memory was measured using the Wechsler logical memory test, and visuospatial memory was assessed using an online card memory game.FindingsHyper-searchers were defined as participants with search percentage of over one standard deviation (SD) above the mean. The average search percentage of the seven participants who met this criterion was 51% (SD = 14%), over five times more than the other participants (M = 10%, SD = 9%). Similar results were obtained by re-analyzing data from four previous papers (N = 1,252). The results further confirmed the hypothesis that hyper-searchers have significantly better verbal memory than other participants, possibly making searching easier and more successful for them. Lastly, the search percentage was positively predicted by verbal memory scores and negatively predicted by visuospatial memory scores. Explanations and future research are discussed.Originality/valueThis preliminary study is the first to introduce the concept of hyper-searchers, demonstrate its existence and study its causes.
