基于双因素模型的老年人生命意义感与心理健康：老化态度的中介作用——基于双因素模型的老年人生命意义感与心理健康：老化态度的中介作用

在积极心理学的影响下,心理健康双因素模型包含主观幸福感和精神病理学指标。研究旨在验证心理健康双因素模型在老年人中的适用性,考察老化态度在生命意义感和心理健康间的多重中介作用。采用爱丁堡幸福量表、一般健康问卷、老化态度问卷和人生意义问卷调查了283名广州市社区老年人。结果发现：（1）心理健康双因素模型较单因素模型的拟合度更优。（2）生命意义感通过老化态度的三条路径（对身体变化、心理获得和心理社会丧失的积极态度）促进心理健康,但具体机制不同。增强意义体验、意义追寻通过老化态度的完全中介作用,提高主观幸福感。增强意义体验通过老化态度的完全中介作用,减弱意义追寻通过老化态度的部分中介作用,减少精神病理学症状。研究结果扩大了心理健康双因素模型的适用年龄范围,为提升老年人的心理健康提供实证依据。     

家庭环境对老年人生活质量的影响:老化态度的中介作用

采用家庭环境量表、老化态度问卷和自编的老年人生活质量问卷调查了700名老年人,以考察家庭环境、老化态度和生活质量之间的关系。结果发现:(1)家庭环境中的亲密性和娱乐性正向预测生活质量。(2)家庭环境中的亲密性和娱乐性还通过老化态度的三条路径影响老年人生活质量:通过生理变化的中介作用;通过心理获得的中介作用;通过心理社会丧失的中介作用。其中,生理变化的中介作用最大,其次是心理获得和社会心理丧失。研究结果揭示了家庭环境对老年人生活质量的作用机制,能为提升老年人的生活质量提供理论指导。     

成功的老年──近期老年学领域一个新的研究主题

“成功的老年”是近３０年来老年学领域提出的一个新的科学概念和模型．“成功的老年”是相对于“普通的老年”而言的,它不仅仅是寿命的延长,更重要的是通过生理因素和心理社会因素的积极作用,提高年老过程的生命质量。“成功的老年”可通过身心健康、认知功能、社会能力、生活满意度等多项指标来衡量。“成功的老年”在成为老年学领域一个重要的研究方向．     

情景记忆成功年老化的神经机制

随着年龄的增长, 大部分老年人的情景记忆会出现衰退, 但也会有一部分老年人的情景记忆表现出成功的年老化, 即记忆成绩较好或随增龄的衰退程度较小。脑保持理论、神经去分化理论、认知储备理论以及神经补偿理论分别从不同角度解释了情景记忆成功年老化的神经机制。基于选择性优化与补偿模型对现有理论进行整合, 发现情景记忆成功年老化可能与个体的认知储备水平直接相关：高认知储备的老年人能够对情景记忆相关的脑区和脑网络进行优化且具备更强的神经补偿能力, 因而其脑功能(比如, 神经表征和神经加工通路的特异性)可能会保持地更好。未来研究需要更多地采用纵向设计来考察各理论之间的关系及其影响因素, 从而更好地解释记忆成功年老化的神经机制并为提升老年人的脑与认知健康提供支持。     

农村老年人社会参与对老化态度的影响：自我效能感和孤独感的中介作用

本文从积极老龄化的角度,采用入户问卷调查的方式,探究了河南某地农村老年人社会参与对其老化态度的影响,以及自我效能感和孤独感在二者关系中的作用。研究结果显示,社会参与对老化态度具有积极的促进作用,同时,自我效能感、孤独感以及自我效能感与孤独感的链式中介效应在社会参与和老化态度之间起部分中介作用。因此,提高农村老年人的社会参与度,能够一定程度上改变老年人的认知,减少消极情绪,促进成功老化。     

老年人的智慧

智慧是个体在其人生经历中习得的一种德才一体的综合心理素质, 是成功老龄化的重要标志和毕生发展的理想终点。研究发现, 三维智慧量表、自我评估智慧量表、成人自我超越问卷等自陈式测量和柏林智慧范式、智慧推理等表现式测量对老年人智慧评估具有良好性能; 老年人智慧发展受到开放性、自我反思、情绪调节、人格成长等内在因素以及受教育程度、关键生活经历、社会环境等外在因素的交互影响; 毕生发展的智慧为老年人带来更高主观幸福感、生活满意度以及更少社会疏离感、孤独感和抑郁。未来应该开发多测度、整合的老年人智慧测评工具; 深入揭示老年人智慧的预测因素、影响后效及其内部作用机制; 进一步探索社区养老服务中老年人智慧的干预与培育策略。     

老年人医疗语篇理解的影响因素和补偿模型

医疗语篇理解是老年人实现自我照护的关键因素,改善老年人医疗语篇理解有助于提高其生存质量并节约医疗成本。本文整理了老年人医疗语篇理解的影响因素,包括加工能力等老年人个体因素和可读性等语篇设计因素,并在此基础上提出了老年人医疗语篇理解补偿模型。该模型尝试阐述上述各影响因素中,那些随龄衰退的因素(如加工能力),如何从别的因素中得到补偿(如医疗知识),从而支撑老年人的医疗语篇理解。补偿模型有利于干预研究的设计,但也还有待更多的实证研究。     

认知老化对于老年人决策过程的影响:动机的调节作用

有关老化和决策制定的研究并没有发现一致的年龄差异。从决策过程的角度,论述了老化对于决策制定的多层面影响。从认知层面来讲,流体认知能力的衰减会使老年人在决策制定前搜索更少的信息,使用非补偿性策略,基于属性进行信息搜索和比较;晶体认知能力的相对保持则在一定情况下弥补了这种消极影响;从动机层面来讲,关注情绪管理目标的老年人会倾向于寻求更多积极的信息,为了避免权衡诱发的消极情绪而更多地使用非补偿性策略。动机对于认知老化的消极影响有调节作用。具体来说,社会情绪选择理论和选择性投入假设认为,当决策任务符合老年人的社会目标,即情绪管理目标时,能够激活老年人投入认知资源的动机,从而缓解认知资源的衰减对于老年人决策表现的消极影响。未来的研究需要通过实验设计进一步探索动机与认知的交互作用,将多种过程追踪技术结合起来,明晰动机和认知能力在老年人决策制定中的作用。另外考虑到在社会目标方面的年龄差异,对于老年人决策质量的衡量应该更加注重主观决策质量。     

老年人重要社会支持的特点及其与老化态度的关系

采用重要他人和老化态度问卷测查了441名老年人的社会支持和老化态度情况,并且从支持的数量和质量角度以及实际支持和期望支持的角度细致考察了社会支持与老化态度的关系。结果表明：（1）老年人的支持来源符合社会支持层级模式;（2）性别、年龄及受教育水平对老年人社会支持有显著影响;（3）老年人从重要他人那里获得的实际社会支持的质量越高,老化态度越积极。     

老化对睡眠依赖性记忆巩固的影响

随着老化的发生和发展, 老年人的睡眠和记忆问题变得越来越突出。研究显示老年人针对程序性记忆的睡眠依赖性巩固能力受损, 而针对陈述性记忆的睡眠依赖性巩固研究结果尚存分歧。此外, 患有神经退行性疾病的老年人在正常老化的基础上伴有情景记忆睡眠依赖性巩固能力受损。未来研究应考虑同步采集脑电和脑成像数据, 探索增龄通过睡眠影响记忆的神经通路, 尝试搭建老化、睡眠以及记忆三因素的交互模型, 并从睡眠对记忆巩固影响的角度提出针对老年人记忆问题的干预措施。     

老年人日常人际问题解决中的悲伤情绪体验和情绪调节策略: 年龄和人格特质的作用

考察了日常人际问题解决中老年人的悲伤情绪体验和情绪调节策略与青年人的差异,以及年龄和人格特质的作用。共45名老年人和59名青年人接受半结构化访谈和人格特质测量。结果表明：（1）以教育水平为协变量的方差分析表明,老年人和青年人的悲伤情绪体验没有显著差异。老年人的被动情绪调节策略的使用和青年人存在显著差异;（2）老年人的被动情绪调节策略不但与年龄有关,而且与悲伤情绪体验有关。悲伤情绪体验可以显著预测其被动情绪调节策略使用;（3）老年人的悲伤情绪体验与人格特质神经质维度存在显著正相关;（4）老年人与年轻人的被动情绪调节策略都与悲伤情绪有关,但老年人的被动情绪调节策略不能由人格特质显著预测,而青年人的被动调节策略还可以由人格特质内外向维度显著预测。人格特质的内外向维度对老年人和青年人的前摄性情绪调节策略的预测效应是一致的。最后针对老年人的悲伤情绪体验和情绪调节策略的意义进行了讨论。     

THE RELATIONSHIP BETWEEN FUTURE TIME PERSPECTIVE AND MEMORY CONTROL BELIEFS IN OLDER ADULTS

In studies with older adults, future time perspective (FTP) is most frequently assessed using the Carstensen and Lang FTP scale. However, it has been proposed that that this scale is actually composed of three interrelated subcomponents. Within a sample of 189 community-dwelling older adults (aged 60–85), we replicated a three-component structure. We also found that these subscales vary in their relationships to other measures of time perspective (i.e., future time attitudes and perceived life progress), and in their relationships to control beliefs about memory. These findings complement prior research documenting a link between FTP and control beliefs by showing that the magnitude of this association varies across FTP components. Understanding the interplay between FTP and memory control beliefs is also important as both predict important age-related outcomes and may be modifiable via intervention. The reciprocal relationship between these factors and the implications for successful aging are discussed.     

Aging: a switch from automatic to controlled processing of sounds?

In this article, the authors show that aging differentially affects peoples' ability to automatically and voluntarily process auditory information. Young, middle-aged, and older adults matched behaviorally in an auditory discrimination task showed similar patterns of neural activity indexing the voluntary and conscious detection of deviant (i.e., target) stimuli. In contrast, a negative wave indexing automatic processing (the mismatch negativity) was elicited only in young adults for near-threshold stimuli. These results indicate that aging affects the ability to automatically register small changes in a stream of homogeneous stimuli. However, this age-related decline in automatic detection of small change in the auditor environment can be compensated for by top-down controlled processes.     

The role of executive functioning in CBT: a pilot study with anxious older adults

Cognitive behavior therapy (CBT) is an effective treatment for late life anxiety and depression. The successful use of CBT is assumed to rely on cognitive skills known as executive functions (EF; e.g., hypothesis generation, allocation of attention, self-monitoring) governed by the prefrontal cortex. Because older adults sometimes have executive deficits as a consequence of normal aging, EF may be a mediator of CBT outcome in older samples. The current pilot study tested the hypothesis that older adults with executive deficits (as measured by neuropsychological tests) would show decreased therapeutic benefit from CBT for generalized anxiety disorder, as compared to a group with intact EF. Results indicated differential response to CBT within the dysfunction group depending on the stability (and possibly, the etiology) of executive deficits from pre- to posttreatment. Those whose EF scores remained low from pre- to posttreatment did not respond to CBT, while those whose scores improved responded quite well, similar to an Intact EF group. Results indicate that some, but not all, older adults with executive dysfunction show decreased benefit from CBT, and are consistent with the assumption that executive skills are important for the successful use of CBT. However, some participants may show improvement on both mood and cognitive skills during treatment, which is discussed further.     

Experimental Evaluation of Near‐ and Far‐Transfer Effects of an Adaptive Multicomponent Working Memory Training

An important question in cognitive science today is whether working memory training leads to transfer effects. Training studies reported no transfer as well as far transfer to untrained abilities (e.g., reasoning), but different methodological problems have not allowed reliable conclusions to be drawn. Furthermore, most samples have consisted of young adults, whereas older adults have rarely been included. This study attempted to address these limitations. Ninety‐one older adults were randomly assigned to a training group or an active or passive control group. Short‐term memory, speed, and reasoning were assessed as far‐transfer criteria. In addition, transfer to everyday life was investigated using an ambulatory assessment method. Although there were significant training effects, no transfer effects were found. Instead, the active control group showed the same increase in the near‐transfer tasks (i.e., working memory) as the experimental group indicating that unspecific factors explain the training gains of older adults.

Strength and vulnerability integration: a model of emotional well-being across adulthood

The following article presents the theoretical model of strength and vulnerability integration (SAVI) to explain factors that influence emotion regulation and emotional well-being across adulthood. The model posits that trajectories of adult development are marked by age-related enhancement in the use of strategies that serve to avoid or limit exposure to negative stimuli but by age-related vulnerabilities in situations that elicit high levels of sustained emotional arousal. When older adults avoid or reduce exposure to emotional distress, they often respond better than younger adults; when they experience high levels of sustained emotional arousal, however, age-related advantages in emotional well-being are attenuated, and older adults are hypothesized to have greater difficulties returning to homeostasis. SAVI provides a testable model to understand the literature on emotion and aging and to predict trajectories of emotional experience across the adult life span.     

Effects of aging and encoding instructions on emotion-induced memory trade-offs

The effects of emotion on memory are often described in terms of trade-offs: People often remember central, emotional information at the expense of background details. The present experiment examined the effects of aging and encoding instructions on participants' ability to remember the details of central emotional objects and the backgrounds on which those objects were placed. When young and older adults passively viewed scenes, both age groups showed strong emotion-induced trade-offs. They were able to remember the visual details as well as the general theme of the emotional object, but they had difficulties remembering the visual specifics of the scene background. Age differences emerged, however, when participants were given encoding instructions that emphasized elaborative encoding of the entire scene. With these instructions, young adults overcame the trade-offs (i.e., they no longer showed impairing effects of emotion), whereas older adults continued to show good memory for the emotional object but poor memory for its background. These results suggest that aging impairs the ability to flexibly disengage attention from the negative arousing elements of scenes, preventing the successful encoding of nonemotional aspects of the environment.
