成年人日常生活记忆的研究 总被引:9,自引:0,他引:9
采用三项记忆作业,对120例20—85岁的被试进行日常记忆和实验室记忆的比较研究,目的为探讨日常记忆的年龄差异及其年老化特点。结果表明:(1)三项记忆成绩均随增龄而减退,其中年老老年组减退明显;(2)作业难度比较:经方差分析结果表明,它对记忆成绩有显著作用,作业难度自评与方差分析相符,“地名”最易,“人姓”居中,“无意义图形再认”最难,因为“地名”为日常生活记忆,难度小于后者(为实验室记忆)。老年人日常生活记忆减退缓慢,他们可利用知识经验补偿记忆减退,使之保持较好。 相似文献

Although women evidently have higher depression levels than men and singles have higher depression levels than the married, the reasons for these differences are yet unclear. This paper investigates whether differences in the stress-producing circumstances of the lives of men and women, and the married and unmarried, might explain the differences in their levels of depression. Using data from the National Survey of Families and Households, we found that gender differences in depression were accounted for by chronic strains. Family-based strains and economic hardship are significant predictors of higher distress in women. Chronic strains also explain why variations in depression are more pronounced among the married than among the unmarried.Bowling Green State University 相似文献

50—90岁成人的短时记忆研究 总被引:1,自引:0,他引:1
本工作研究了102例50—90岁成人的短时记忆,其中85例进行了较详细的体格检查。以22例20—25岁青年的记忆检查作为对照,结果看到: 1.在图片自由回忆、逻辑故事识记、数字广度识记三个项目上,记忆都有随年龄增长而逐步减退的明显趋势; 2.识记逻辑故事时,对中心意义的记忆减退较分节记忆减退缓慢,顺背数字的记忆广度随年龄增长而减小较其他项目都要缓慢,表明老年记忆减退有其特点; 3.神经系统和心血管系统的病理性或老年性变化与记忆减退有关。 相似文献

从实验动物材料和人的临床研究早已提出颞叶,特别是它的深部核团和结构——杏仁核和海马,对情绪和行为的控制起重要作用。廿多年来已广泛地研究了海马的θ节律和其他电活动,提出了一些与行为相关的海马电活动理论。有人认为,海马的慢同步活 相似文献

以往研究显示,知觉组织影响时序知觉,采用ERP技术拟探讨知觉组织影响时序知觉的认知机制。采集23名被试完成同时判断任务的脑电数据。行为结果发现,知觉组织影响时序知觉,具体表现为知觉组织条件的同时判断频率显著高于非知觉组织条件。ERPs结果发现,在P1和P2成分上,知觉组织条件与非知觉组织条件引发的波幅没有显著差异; 而在N1成分上,知觉组织条件诱发的N1波幅显著大于非知觉组织条件。这表明,知觉组织对时序知觉的影响可能发生在视觉刺激加工的早期阶段,视觉刺激的知觉组织先于时序信息加工。 相似文献

The calibration of the one-parameter logistic ability-based guessing (1PL-AG) model in item response theory (IRT) with a modest sample size remains a challenge for its implausible estimates and difficulty in obtaining standard errors of estimates. This article proposes an alternative Bayesian modal estimation (BME) method, the Bayesian Expectation-Maximization-Maximization (BEMM) method, which is developed by combining an augmented variable formulation of the 1PL-AG model and a mixture model conceptualization of the three-parameter logistic model (3PLM). By comparing with marginal maximum likelihood estimation (MMLE) and Markov Chain Monte Carlo (MCMC) in JAGS, the simulation shows that BEMM can produce stable and accurate estimates in the modest sample size. A real data example and the MATLAB codes of BEMM are also provided. 相似文献

Despite the high prevalence of suicidal ideation and attempts among homeless youth, little research has examined how suicide prevention interventions influence suicide-related risk and protective factors, and ultimately produce positive outcome in suicidality in this population. Drawing on the Diathesis-Stress Model and the Interpersonal Theory of Suicide, the current study examined whether participation in Cognitive Therapy for Suicide Prevention (CTSP) moderated the mediation link between social problem-solving, perceived burdensomeness and thwarted belongingness, and suicidal ideation among a sample of homeless youth experiencing suicidal ideation. Social problem-solving refers to a set of cognitive, emotional, and behavioral coping responses in the face of stressful situations, and it is identified as a potent protective factor in alleviating perceived burdensomeness and thwarted belongingness, and reducing suicidal ideation. Participants included 150 homeless youth (M age = 20.99, range = 18-24; 41% female) who were randomly assigned to Cognitive Therapy for Suicide Prevention (CTSP) + Treatment as Usual (TAU) (n = 75) or Treatment as Usual alone (n = 75). Participants were assessed at baseline, 3, 6, and 9 months post-baseline. Findings showed that perceived burdensomeness mediated the association of social problem-solving with suicidal ideation only among youth participating in the CTSP condition. These findings provide evidence to support the promising effects of CTSP in enhancing the protective effects of social problem-solving on suicidal ideation through the mediating effects of perceived burdensomeness. Findings also have implications for improving intervention effectiveness with a community-based population at high risk of suicide. 相似文献
