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   

提升聋生“内存”四法     

Zhang Qin 《南京特教学院学报》2008,(3)

聋生学习和运用所学语言文字来记叙事情、表达思想都存在一个共同的现象:说话缺乏中心,思想表达不清,作文无从下手。教师如何改善聋生现状,提高他们的语言表达能力,值得聋教育工作者进行探讨。笔者认为,应从提高聋生的语言积累入手,扩大聋生的阅读范围,丰富聋生的词汇量,加强聋生的语言实践,从根本上提升聋生的"内存"。  相似文献

本实验以视觉系列呈现方式 ,在形近、音近、义近三种干扰下以再认方法比较了听力正常人与聋人对字频与笔画二种不同水平汉字材料的短时记忆容量及编码方式 ,研究结果表明 :( 1 )聋人与听力正常人短时记忆容量差别有限 ,只存在于低频复杂汉字组中。 ( 2 )高频字中 ,聋人短时记忆编码以形码为主 ,义码次之 ,音码最弱 ;听力正常人则以音码为主 ,义码次之 ,形码作用最弱。 ( 3 )低频字中 ,低频简单组中表现出与高频字相同的编码方式 ,低频复杂组中聋人与听力正常人均表现形码、义码为主 ,音码作用弱的特点  相似文献   

《纪念刘和珍君》和《为了忘却的纪念》比较     

王淑萍 《洛阳师范学院学报》2000,19(3):127-130

鲁迅《纪念刘和珍君》和《为了忘却的纪念》两篇杂文 ,主题思想和写作方法大体相同 ;但因为纪念对象和写作时间的具体差异 ,受作者思想发展的阶段性影响 ,各自表现出来的认识结论有所不同。在表达手法上 ,前者以叙事为主 ,抒情淋漓酣畅 ,风格激越 ;后者以抒情为主 ,表达曲折含蓄。把握这些区别 ,对合理设置教学目标、实施教学计划 ,有非常重要的意义  相似文献

Overconfidence in children's multi-trial judgments of learning     

《Learning and Instruction》2014

The underconfidence with practice effect (UWP) refers to the finding that people's judgments of learning shift from overconfidence to underconfidence on and after a first study-test trial (Koriat, Ma'ayan, & Sheffer, 2002). Finn and Metcalfe (2007, 2008) proposed that people show UWP because they use their memory of prior test performance as a cue to make subsequent judgments of learning and inadequately account for new learning (i.e. the Memory for Past Test (MPT) heuristic). In contrast to adults, 3rd and 5th graders' judgments showed persistent overconfidence on and after a first study-test trial. A second experiment tested children's ability to remember their prior test performance. Children's prior performance discriminations were accurate for items that they answered correctly on the prior trial, but were overconfident for items they had answered incorrectly indicating that their continued overconfidence was a result of faulty memory, rather than a failure to use the MPT heuristic.  相似文献   

Aspect-based sentiment analysis with alternating coattention networks     

Chao Yang  Hefeng Zhang  Bin Jiang  Keqin Li 《Information processing & management》2019,56(3):463-478

Aspect-based sentiment analysis aims to predict the sentiment polarities of specific targets in a given text. Recent researches show great interest in modeling the target and context with attention network to obtain more effective feature representation for sentiment classification task. However, the use of an average vector of target for computing the attention score for context is unfair. Besides, the interaction mechanism is simple thus need to be further improved. To solve the above problems, this paper first proposes a coattention mechanism which models both target-level and context-level attention alternatively so as to focus on those key words of targets to learn more effective context representation. On this basis, we implement a Coattention-LSTM network which learns nonlinear representations of context and target simultaneously and can extracts more effective sentiment feature from coattention mechanism. Further, a Coattention-MemNet network which adopts a multiple-hops coattention mechanism is proposed to improve the sentiment classification result. Finally, we propose a new location weighted function which considers the location information to enhance the performance of coattention mechanism. Extensive experiments on two public datasets demonstrate the effectiveness of all proposed methods, and our findings in the experiments provide new insight for future developments of using attention mechanism and deep neural network for aspect-based sentiment analysis.  相似文献

The effects of implicit encouragement and the putative confession on children’s memory reports     

《Child abuse & neglect》2018

The current study tested the effects of two interview techniques on children's report productivity and accuracy following exposure to suggestion: implicit encouragement (backchanneling, use of children's names) and the putative confession (telling children that a suspect "told me everything that happened and wants you to tell the truth"). One hundred and forty-three, 3–8-year-old children participated in a classroom event. One week later, they took part in a highly suggestive conversation about the event and then a mock forensic interview in which the two techniques were experimentally manipulated. Greater use of implicit encouragement led to increases, with age, in children's narrative productivity. Neither technique improved or reduced children's accuracy. No increases in errors about previously suggested information were evident when children received either technique. Implications for the use of these techniques in child forensic interviews are discussed.  相似文献
