ABSTRACT

Objective: Memory loss affects a large proportion of older adults. Research indicates a positive association between memory training and better memory performance as people age. However, studies on specific memory training using an experimental design are limited. This study explored whether memory training has improved memory performance in a group of older adults.

Method: A convenience sample of 48 participants was recruited from two communities. Disregarding dropouts, this left 23 experimental (mean age = 65.4 ± 6.0, range = 56–80) and 19 control participants (mean age = 64.5 ± 4.9, range: 57–72). The intervention consisted of 60-min classes held on a weekly basis continuing for 8 weeks. The class session was held after a 1-h exercise class and before a 1-h session of cognitive games. The pre–post objective memory performances, including associative, list, text, place, grocery learning, and transfer-effect of daily event memory (ecology validity), were examined to determine whether the intervention was effective.

Results: Intragroup: With Wilcoxon test, the findings showed that the intervention of both the list and place learning had significant differences for the experimental group, but not for the control group. Intergroup: The main effects were found for the associative and text learning. The mixed design ANOVA indicated that there is an interaction (time x group) on the dependent variable of the place learning test. Daily events memory: We found within group that the pre–post differences were significant for the experimental group but not for the control group.

Conclusion: The study showed that memory training can help older adults to ameliorate memory loss problems and these findings deserve more attention.  相似文献

This study examined the potential influence of moderate intensity physical activity (PA) levels and gender on central pain modulation using conditioned pain modulation (CPM) in healthy men and women. Twenty four individuals (12 men and 12 women) who reported engaging in the moderate intensity PA for 150 min or more per week and 24 individuals (12 men and 12 women) who reported engaging in moderate intensity PA for 60 min or less per week completed a self-report PA questionnaire and a 7-day PA assessment using an accelerometer. Furthermore, the participants completed the CPM testing to evaluate the efficiency of central pain modulation. The active individuals scored higher on the PA questionnaire and spent more minutes for light, lifestyle, moderate and vigorous intensity PA than the less active individuals. The active men and women exhibited comparable magnitudes of CPM, and showed a greater magnitude of CPM when compared to their less active counterparts. However, these beneficial effects of higher dose moderate intensity PA disappeared when time spent for vigorous intensity PA was statistically controlled for. These results suggest that the higher dose moderate intensity PA does not add to the benefits from vigorous intensity PA to further improve central pain modulatory systems.  相似文献

Academic development has had an approximately forty‐year history within Australian higher education, paralleling the major expansions and changes in the sector, both nationally and internationally. Its principal concerns have been the improvement of teaching and the professional development of the academics who teach. The history of academic development has gone largely undocumented and unexamined at a national level, in Australia and elsewhere. However, as university teaching has increasingly become important in relation to quality in higher education, academic development has become a central player in the work of universities. It becomes of particular importance at this time to garner a more thorough understanding of the continuities as well as the discontinuities in the meanings and practices of university teaching and in the work of those whose role has been to support its development. This article presents a discussion of two key themes identified from a set of oral history interviews conducted with early leaders in academic development in Australia. These themes offer different insights into issues and understandings of academic development in today’s university. The first concerns a perennial issue in academic development – the struggle to define academic development’s emerging ethos in relation to research and service to the broader university’s endeavour. The second theme represents an issue that has been forgotten or marginalised in the official accounts of academic development but which lives on in the ‘lore’ of the field – the role of activism in the shaping of university teaching and academic development.  相似文献

This article explores the discourse of international educational reform that aims at meeting the various challenges of globalisation and a knowledge-based economy and preparing students for a better future in the twenty-first century. Specifically, it reviews the dominant themes, trends and goals of modern education. It does so by exploring the shared themes of curriculum adaptation, the emerging models of learning and innovation, the trend towards lifelong learning for all and the growing need for the internationalisation of education. It concludes by suggesting an overall trend of the sectorisation and de-sectorisation of education emerging under new social and economic circumstances in the twenty-first century.  相似文献

A psychological process called self-referencing justifies the use of ‘you’ statements in advertisements; the more an individual relates an ad to him/herself, the greater the likelihood of recall and favorable evaluation. Self-referencing can be differentiated based on the temporal dimension of the self being activated while processing advertisements: when people remember themselves in the past they engage in retrospective self-referencing whereas they engage in anticipatory self-referencing when imagining themselves in the future. The current study examined the moderating role of consumers’ cultural background (i.e. long-term vs. short-term orientation) on the effects of temporal orientation of self-referencing. A corollary of this premise is that the match between cultural time orientation and the type of self-referencing activated by an ad will increase the extent of viewers’ self-referencing as well as advertising effectiveness. Further, this study confirmed a mediating role of self-referencing in explaining the match effects. The findings inform the extant literature on self-referencing and also provide managerial implications for international advertising practitioners.  相似文献

State and Local governments must develop an overarching legal foundation to manage critical service delivery in an electronic environment. Prior to establishing a foundation, decision-makers must first adopt a philosophy that focuses and harnesses expressions of law and public policy. The research and development community must supports the nation’s efforts with programs designed to aid in the risk assessment process. These programs must focus on identifying better ways to quantify risk, understanding infrastructure interdependency, and measuring cascading damages flowing from service outages. Finally, State and Local leaders should adopt security guidelines for industry and government service providers. Guidelines involve ten well-defined process requirements, all of which must be implemented to provide services online and in a safe and secure manner.  相似文献

This study determined the degree to which the phonological and executive components of memory reflect language‐specific capacities in reading achievement. We tested whether the memory processes in a sample of English‐language learners that played a major role in predicting second‐language acquisition and risk for reading disability (RD) in Grade 1 (Swanson, Sáez, Gerber, & Leafstedt, 2004) also predicted reading performance in Grade 2. The present results showed that Spanish short‐term memory (STM) performance in Grade 1 predicted basic Spanish‐reading skills and Spanish comprehension in Grade 2, whereas Grade 1 English STM performance predicted English vocabulary and English comprehension in Grade 2. More importantly, children at risk for RD in Grade 1 differed from the counterparts in Grade 2 on both English and Spanish measures of reading, whereas their memory deficits were isolated to Spanish STM and working memory (WM). The relationship between language‐specific processes in memory and reading are discussed.  相似文献
