老年人情绪注意积极效应的发生机制

20世纪, 许多心理学家从“厄运与苦难”视角研究人晚年遭遇的身体、认知和情绪衰老, 但是近年的理论与实证研究从“老化悖论”——老年人情绪加工的积极效应——视角挑战这一“定论”。积极效应指老年人认知加工过程中比年轻人更偏好正性而非负性材料的现象。第二代社会情绪选择理论包括积极效应理论、认知控制假说和强弱整合模型3个关于认知和情绪功能年龄差异的理论模型, 特别强调了认知控制在老年人积极情绪加工中的潜在作用, 而自动化加工与控制性加工的区分则取决于注意资源配置。因此, 认知控制在老年人对积极情绪的注意加工中起重要作用。此外, 注意偏向的时间进程也是影响老年人情绪注意中积极效应的关键因素。最后, 综合以往研究构建出认知控制对老年人积极效应发生作用的注意阶段模型。未来研究可从中国老年人情绪注意加工模式、不同认知控制子成分的作用机制、提高研究生态学效度和注意的治疗品质几个方面继续探索。     

正常老化对视觉早期注意的影响——来自ERP的证据

选择性注意能够作用于视觉信息加工的不同阶段。各个注意阶段均受到老化过程的影响,其中注意早期阶段的老化研究对于理解认知老化的发生机制有重要意义。本文系统地梳理了刺激前的注意预期阶段以及刺激后200 ms内的早期感知注意阶段的正常老年人和青年人ERP比较研究,以探讨正常老化对视觉早期注意的影响。现有证据表明,相对于青年人,正常老年人：(1)多个早期ERP注意效应(包括注意预期ADAN,早期空间注意N1,以及特征注意SP和SN)在潜伏期上都存在显著延迟;(2)在振幅上,不同ERP注意效应的老化表现存在差异：某些ERP成分(包括注意预期EDAN,以及早期空间注意P1)的注意效应没有明显减弱,而某些ERP成分(包括注意预期alpha,早期空间注意N1,以及特征注意SN)的注意效应受到老化调控;(3)一些注意效应(包括特征注意SP成分,以及客体注意P1和N1成分)的目标增强机制保留,而干扰抑制机制缺损。目前已有研究在老化对注意效应振幅的调控上还存在不一致,这可能与研究的信噪比、任务难度、注意机制分离以及老年人的个体差异有关。未来研究应考虑这些因素以更好地探究正常老化对视觉早期注意的影响。     

Lexical prediction in the aging brain: The effects of predictiveness and congruency on the N400 ERP component

Although the N400 ERP component has been extensively studied in younger adults, the underlying mechanisms are still unclear. In older adults, N400 ERP studies have shown less efficient use of context compared to younger adults. Here, we asked whether the mechanisms underlying the N400 effect are the same in terms of predictiveness and congruency in younger and older adults. We used a simple picture-word matching task in which we crossed predictiveness and congruency. Our results indicate a three-way interaction between predictiveness, congruency, and age, in that, younger adults showed an N400 effect only in strongly constrained conditions; whereas, older adults showed an effect in both strongly- and weakly constrained conditions. This interaction was not modulated by language experience or cognitive decline. Our results support either two separate mechanisms (lexical access and integration) that run in parallel and are modulated by age or a common prediction error mechanism that changes with age.     

Assisting Older Women in Combatting Ageist Stereotypes and Improving Attitudes Toward Aging

Ageism is a pervasive force in society that poses a significant threat to the well-being of older women. This article integrates theory, research and practice in an examination of ageism as it relates to therapy with older women. The authors review common stereotypes of older women, and discuss the pervasiveness of these stereotypes using a terror management explanatory framework. Particular attention is also paid to the effects of ageist stereotypes on older women, with especial emphasis on stereotype threat and self-stereotyping concepts. The authors argue that geriatric rehabilitation settings may enhance vulnerability to these negative effects. Finally, strategies for older women to combat ageist stereotypes and develop positive attitudes toward aging are discussed. Implications for therapeutic practice to help older women maintain a satisfying quality of life, despite these stereotypes, are presented throughout the article. The authors recommend interventions embedded in feminist theory, positive psychology, and humanistic and cognitive–behavioral therapies.     

Emotion identification across adulthood using the Dynamic FACES database of emotional expressions in younger,middle aged,and older adults

Facial stimuli are widely used in behavioural and brain science research to investigate emotional facial processing. However, some studies have demonstrated that dynamic expressions elicit stronger emotional responses compared to static images. To address the need for more ecologically valid and powerful facial emotional stimuli, we created Dynamic FACES, a database of morphed videos (n?=?1026) from younger, middle-aged, and older adults displaying naturalistic emotional facial expressions (neutrality, sadness, disgust, fear, anger, happiness). To assess adult age differences in emotion identification of dynamic stimuli and to provide normative ratings for this modified set of stimuli, healthy adults (n?=?1822, age range 18–86 years) categorised for each video the emotional expression displayed, rated the expression distinctiveness, estimated the age of the face model, and rated the naturalness of the expression. We found few age differences in emotion identification when using dynamic stimuli. Only for angry faces did older adults show lower levels of identification accuracy than younger adults. Further, older adults outperformed middle-aged adults’ in identification of sadness. The use of dynamic facial emotional stimuli has previously been limited, but Dynamic FACES provides a large database of high-resolution naturalistic, dynamic expressions across adulthood. Information on using Dynamic FACES for research purposes can be found at http://faces.mpib-berlin.mpg.de.     

Aging in cognitive control of social processing: evidence from the attention network test

ABSTRACT

Aging seems to be associated with impairment of attentional network functioning. It is not known whether social information can modulate this age-related decline. We used three variants of Attention Network test to examine the age-related decline of attentional effects in response to stimuli with and without social-cognitive content. Three groups of younger, middle-aged, and older participants performed the ANT, using fish, drawings, or photographs of faces looking to the left or right as target and flanker stimuli. The results showed that both executive attention and alerting were more resistant to the age-related decline with social stimuli and that orienting attention scores showed a progressive increase with age in the presence of this kind of stimuli. These findings underline the importance of social information in modulating and contrasting the age-related decline and support the status of human faces as a special class of visual stimuli for the human attentional systems.     

A Woman'S Voice As Her Life Changes

Our innate capacity for voice is with us from the beginnings of life. The concept of voice is a complex issue rooted in the core of the self. Once we become aware of ourselves, we realize our capacity for self-expression. Self-expression is part of the cooperative network of communication between the self and others as we share emotions, thoughts, and ideas. Voice facilitates a connection between the world of one individual and the world of another. The purpose of this article was to explore and discover the processes, influences, attitudes and beliefs that affect a woman's ability to define her menopausal voice. A woman's voice expresses her knowledge, set of assumptions, concepts, values, and practices in the form of language. Voice becomes a manifestation of the essence of self, and when listened to, breaks the silence of non-existence. A menopausal woman's voice is the voice that expresses the entirety of her existence at that particular stage in life. Post-menopausal women were asked to define their menopausal voices. They were interviewed in depth and their information was collected through semi-structured interviews. This approach used a qualitative methodology with a focus on meaning of their voices rather than measurement. The format was narrative research using life stories and thematic analysis. As a result, five themes: The Voice of Wisdom, The Voice of Aging, The Voice of relationship, The Voice of Spirit, and the Voice of Knowledge emerged after analyzing the women's stories. Each theme represents the complexities that influenced the participants’ competence to ascribe meaning to their voices. This article identifies the meanings that menopausal women associated with the concept of voice and how it changed during menopause.     

Predicting real-world behaviour: Cognition-emotion links across adulthood and everyday functioning at work

ABSTRACT

Inspired by the discovery of positive age trends in emotional well-being across adulthood, lifespan researchers have uncovered fascinating age differences in cognition–emotion interactions in healthy adult samples, for example in emotion processing, memory, reactivity, perception, and regulation. Taking stock of this body of research, I identify four trends and five remaining gaps in our understanding of emotional functioning in adulthood. In particular, I suggest that the field should pay stronger attention to the prediction of real-world behaviour. Using the sample case of work functioning, I outline gaps in current knowledge, including the lack of data on middle-aged adults, the neglect of relevant cognitive-emotional mechanisms, and the unclear role of life experience. Filling these gaps will enable progress in research on emotional aging in and beyond the work setting and enhance its practical utility for individuals, organisations, and society.     

Working memory predicts subsequent episodic memory decline during healthy cognitive aging: evidence from a cross-lagged panel design

Aging adults experience declines in working memory and episodic memory, however, it is unclear how these declines operate over time. Decreased working memory may be associated with early changes in episodic memory, by reducing older adults’ ability to meaningfully integrate new information into pre-existing schemas and recall information without the assistance of cues. Given the increased prevalence of Alzheimer’s disease, and concerns based on subjective memory changes, it is important to understand how these processes interact over time. To assess the relationship between working memory and episodic memory during healthy cognitive aging, we performed neuropsychological assessments at multiple time points in a sample of 310 community-dwelling older adults. Using a cross-lagged panel design, we demonstrated that the lagged associations between working memory and later episodic free recall were 50% larger than the lagged associations between episodic recall and later working memory, suggesting working memory may be a useful metric of future episodic memory decline.
