The importance of impaired physical health and age in normal cognitive aging

The objective of this study was to investigate the importance of impaired physical health and age in normal cognitive aging. In our cross-sectional, clinical and explorative study, medical and neuropsychological data from 118 voluntary healthy controls aged 26-91 years were collected from five recruitment occasions. Health was assessed according to a criterion reflecting clinical and subclinical severity. The examinations included a clinical investigation, brain neuroimaging, and a comprehensive neuropsychological assessment. Regression analyses showed a significant incidence of clinical and subclinical medical disorders that explained 10.8% of the variation in cognitive performance, while age-related impairment explained 5.6%. Findings of the central nervous system were important but various other medical findings explained about half of the health-related variation. Cognitively demanding tasks were more susceptible to impaired physical health while tasks comprising salient motor- and visual spatial elements were more prone to be impaired by age. Our findings suggest (1) that impaired physical health is more important than chronological age in accounting for cognitive impairment across the adult lifespan, (2) that age and health dissociate with regard to cognitive functions affected, and (3) that selection for so-called "super healthy" elderly people might be justified in cognitive research. Because the prevalent diseases in normal aging are potentially preventable, the present findings promise good prospect for prevention of future cognitive disability among elderly people.     

Social adjustment and symptomatology in two types of homeless adolescents: runaways and throwaways

Previous research on homeless adolescents has largely ignored the distinction between those who have left home on their own volition (runaways), and those who have been forced to leave (throwaways). Fifty-two homeless adolescents in Brisbane, Australia, were assessed to compare male and female runaways and throwaways for social adjustment and symptomatology. Differences for social adjustment (antisocial tendencies and aggression) and symptomatology (social isolation and depression) were predicted. Results indicated that male runaways were significantly more hostile than male throwaways (p less than .001), and significantly more socially isolated than female runaways (p less than .025). Female throwaways, however, were significantly more hostile than male throwaways (p less than .025) and female runaways (p less than .025). Yet homeless males overall had a significantly stronger urge to act out hostility than homeless females (p less than .025). In addition, female throwaways were significantly more antisocial than male throwaways (p less than .001). There were no significant differences for depression. A theory of inner social control (Hirschi, 1969), postulating absence of bonding in earlier socialization, was supported.     

Encouraging the practice of testicular self-examination: a field application of the theory of reasoned action

Identified factors associated with testicular self-examination (TSE) within the context of the theory of reasoned action. Subjects (232 male college students) received instruction in TSE and completed a questionnaire operationalizing the components of the theoretical model. During the following 6 weeks, a field intervention was conducted in which approximately half the subjects were exposed to posters reminding them to perform the exam. Multiple-regression analyses revealed that intention to perform TSE correlated significantly with attitude and subjective norm and that consideration of self-efficacy and TSE knowledge improved the prediction of intention. Significant differences in outcome expectancies and normative beliefs were found between subjects who intended to perform the exam and those who did not. Intention was moderately (r = .30, p less than .001) correlated with behavior; the intention-behavior correlation, however, was stronger among subjects who intended to perform the exam and were exposed to the posters (r = .55, p less than .001).     

Social relationships, social support, and patterns of cognitive aging in healthy, high-functioning older adults: MacArthur studies of successful aging.

This study examines the relationship of social ties and support to patterns of cognitive aging in the MacArthur Studies of Successful Aging (see L. F. Berkman et al., 1993), a cohort study of 1,189 initially high-functioning older adults. Baseline and longitudinal data provide information on initial levels as well as changes in cognitive performance over a 7.5-year period. Linear regression analyses revealed that participants receiving more emotional support had better baseline performance, as did those who were unmarried and those reporting greater conflict with network members. Greater baseline emotional support was also a significant predictor of better cognitive function at the 7.5-year follow-up, controlling for baseline cognitive function and known sociodemographic, behavioral, psychological, and health status predictors of cognitive aging. The findings suggest the potential value of further research on the role of the social environment in protecting against cognitive declines at older ages.     

21世纪中国老年心理学研究:现状与未来

本文回顾了近40年中国老年心理学的研究成果,并从研究主题角度与美国老年心理学研究进行了比较。发现中国老年心理学主要聚焦于老年人心理健康研究,同时也在老年人家庭人际关系和社会支持领域研究有较为丰富的研究成果。但国内对老年人的认知能力、人格、情绪情感探讨较少,既缺少前沿的基础研究,也缺少对复杂能力、复杂情感等的系统研究。结合中国人口老龄化现实,本文提出了21世纪中国老年心理学的未来研究取向：基础研究和应用服务研究的双向结合,中国文化特色取向,个体-环境交互作用取向和个体差异取向。     

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。     

Evaluation of an islandwide screening,assessment and treatment program

This article reports on the effectiveness of the Islandwide Screening, Assessment, and Treatment Program of the Child Development Project in Bermuda. From 1982 to 1984, approximately 1100 families with 2-year-old children were screened for children's cognitive and language delay, for behaviour management problems and for other home characteristics that put children at risk for later school failure. Children who failed the screening and subsequent assessment procedures (of whom random samples received treatment) and samples of others who passed screening and assessment were evaluated from 1984 to 1986 at 4 years of age. This article focuses on the results of the cognitive and language programs; the more problematic behaviour management analyses were reported elsewhere (Miller and Scarr, 1988). The screening procedures and assessment measures developed for this project were themselves evaluated and adjusted to maximize efficiency and costeffectiveness. The screening and assessment procedures proved effective in bringing to the attention of the Child Development Project those families and children who need developmental services, and in not overidentifying normal children as potentially delayed in development. Two kinds of treatment services were compared: The Mother-Child Home Program (MCHP), administered by paraprofessional toy demonstrators, and other interventions tailored by professionals to the language and cognitive problems of the child (called ‘tailored programs’). Children who were not extremely delayed or disturbed were randomly assigned either to the MCHP or to a tailored program. Neither intervention program was preferable to the other. Even though improved, the 4-year-olds identified as developmentally delayed at 24 months still lagged behind children who passed all parts of screening and those who failed screening but passed assessment 2 years earlier. The screening and assessment procedures were very effective in the early identification of children with developmental problems, but the treatment programs failed to bring most children to normal levels of cognitive and language functioning.     

Aging and stereotype suppression

Recent work in social cognitive aging has suggested that older adults are more likely than younger adults to activate and use stereotypic information, even when they intend not to. Furthermore, evidence suggests that older adults have difficulty altering their interpretation of a situation, even when it has become clear that their initial interpretation is incorrect. In the current study, younger and older adults read a series of narratives in which a character had a sex-stereotyped occupation (e.g., a plumber is stereotypically male), and the character's gender was either consistent or inconsistent with that stereotype. Explicit labeling of gender was also varied. Results revealed that with explicit labeling, older adults were able to discount their stereotypes and avoid processing difficulties when subsequent stereotype-inconsistent information was encountered. These data suggest that when counter-stereotypic information is explicitly provided at encoding, older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that interpretation is incorrect. These findings indicate that although older adults are more prone to the influence of unwanted stereotypes, this effect can be averted and judgments can be made more egalitarian by providing older adults with explicit stereotype contradiction at encoding.     

Age-related change in visual information processing: Toward a unified theory of aging and visual memory

Memory for semantic information is relatively preserved through the normal aging process. Visuospatial memory remains less intact. In the present article a theory is proposed that links this processing difference to normal age-related generalized cognitive slowing, and to the appearance of specific age-related differences in memory performance. Evidence for these suggestions is presented from work in four areas: mental rotation, spatial memory, paired-associates learning, and free recall. Cognitive performance in young and older respondents is shown to vary predictably with systematic variation of visuospatial and semantic stimulus factors consistent with these hypotheses. A further test of these ideas derives from the development of a clinically useful mnemonic system for older adults that is based on these principles. Taken together, this research indicates that much of the deficit observed in the memory performance of older adults may derive not from memory problems per se, but rather from the action of generalized cognitive slowing, which contributes to diminished abilities to represent and process visual images. This series of findings may provide a framework for understanding a wide variety of the processes involved in aging and visual memory, and for the creation of applications to aid the memory of older adults.     

Ageism in Mental Health and Health Care: A Critical Review

Discussions of aging and mental health widely assume that ageism among mental health providers is an important factor limiting access to mental health services for older adults. Given the widespread citation of ageism as a problem, we critically review the history of the ageism construct, and evidence for its existence in both mental health and medical professionals. There is surprisingly little empirical evidence for age bias among mental health providers. Considerable evidence does suggest differential medical treatment for older adults in such diverse areas as physician–patient interaction, use of screening procedures, and treatment of varied medical problems, although it is unclear whether age bias accounts for these differences. We suggest that innovations in delivery of psychological services, such as collaborative medical/psychological care in primary care settings, may ultimately prove more useful in improving access to mental health services than efforts to combat ageism.     

Experience of Parental Marital Dissolution Earlier in Life and the Disposition to Forgive Among Older Violent and Non-Violent Prisoners

The purpose of this study was to examine differences in self-reported dispositional forgiveness types among older male prison inmates who experienced parental separation/divorce earlier in life. Participants included a sample of N = 261 incarcerated men, aged 45 and older, residing in state-managed prisons in Oklahoma. IBM/SPSS 22.0 was used to examine mean differences across forgiveness of self, situation, and others. Significant mean differences were evident only for forgiveness of situation. In particular, significant differences emerged relative to depressive affect F (1, 192) = 19.90, p < .001, and social support F (1, 192) = 18.64, p < .001. After controlling for age, race, religiosity, depression, social support, perceived health, crime type, and parental separation/divorce, one significant interaction (crime type X parental separation/divorce) emerged, F (1, 192) = 4.42, p < .05. It appears that the disposition to forgive the situation among older prison inmates depends on criminal offender type as well as whether the older inmate experienced parental dissolution earlier in life. Implications for pastoral counseling programing and forgiveness therapy treatment for older male prison inmates who experienced parental separation/divorce earlier in life are discussed.     

The relationship between aging expectations and various modes of physical activity among aging adults

ObjectivePrevious research has indicated that older adults who expect decline and disease with age are less likely to engage in aerobic exercise. This study explores the influence that different types of aging expectations have on various modes of physical activity (PA) among aging adults.Design & methodsCommunity-dwelling adults aged 41–97 years (M = 70.8, SD = 12.8, n = 247) completed a questionnaire including the Physical Activity Scale for the Elderly, the Expectations Regarding Aging (ERA) Survey, and a number of demographic, socio-economic, and medical covariates.ResultsBivariate analyses revealed significant relationships between overall ERA scores and multiple modes of PA, but not at multivariate levels. Bivariate analyses of the ERA sub-scales revealed significant associations among PA and the physical health ERA sub-scale but not mental health or cognitive function ERA sub-scales. In the multivariate analyses, higher physical health ERA was correlated with strenuous sport and recreational physical activities after adjusting for all covariates among aging adults without restrictions of daily activity (OR = 1.01, CI = 1.00–1.02, n = 194).ConclusionsThe association between aging expectations and PA appears to be dependent on the type of aging expectation (i.e., physical health), the mode or intensity of PA, and the functional abilities of the aging adult.     

Aging and Stereotype Suppression

ABSTRACT

Recent work in social cognitive aging has suggested that older adults are more likely than younger adults to activate and use stereotypic information, even when they intend not to. Furthermore, evidence suggests that older adults have difficulty altering their interpretation of a situation, even when it has become clear that their initial interpretation is incorrect. In the current study, younger and older adults read a series of narratives in which a character had a sex-stereotyped occupation (e.g., a plumber is stereotypically male), and the character's gender was either consistent or inconsistent with that stereotype. Explicit labeling of gender was also varied. Results revealed that with explicit labeling, older adults were able to discount their stereotypes and avoid processing difficulties when subsequent stereotype-inconsistent information was encountered. These data suggest that when counter-stereotypic information is explicitly provided at encoding, older adults are no more likely than younger adults to rely on stereotypes, and are similarly capable of altering their interpretation of a situation when information suggests that interpretation is incorrect. These findings indicate that although older adults are more prone to the influence of unwanted stereotypes, this effect can be averted and judgments can be made more egalitarian by providing older adults with explicit stereotype contradiction at encoding.     

Psychological and socioeconomic health of community‐dwelling older adults

Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community‐dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community‐dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young‐old older adults had better psychological and socioeconomic health than middle‐old and old‐old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non‐exercisers.     

Longevity increased by positive self-perceptions of aging

This research found that older individuals with more positive self-perceptions of aging, measured up to 23 years earlier, lived 7.5 years longer than those with less positive self-perceptions of aging. This advantage remained after age, gender, socioeconomic status, loneliness, and functional health were included as covariates. It was also found that this effect is partially mediated by will to live. The sample consisted of 660 individuals aged 50 and older who participated in a community-based survey, the Ohio Longitudinal Study of Aging and Retirement (OLSAR). By matching the OLSAR to mortality data recently obtained from the National Death Index, the authors were able to conduct survival analyses. The findings suggest that the self-perceptions of stigmatized groups can influence longevity.     

Depression Screening in Medically Ill Homecare Elderly

PURPOSE: This article provides data on a depression screening model (HOME) in acute home health care designed to detect clinical depression among medically ill homebound older patients. The model was developed to address the lack of mental health services in home health care settings and to specifically improve geriatric depression screening as part of routine care. Authors report on the concordance of homecare and research interview ratings of depression in older homecare patients. DESIGN AND METHODS: Using a prospective cohort design, data were collected from 289 elderly patients, aged 65 and older, from a large home health care agency to examine depression, cognitive functioning, medical comorbidity, functional status, and social isolation. Research interviews used the depression module of the structured clinical interview for DSM (SCID). RESULTS: The overall prevalence of major depression was 5.7 percent according to both homecare and research raters. The prevalence of subthreshold depressive disorder was 16.4 percent as reported by research raters. Observed agreement was 73 percent and kappa agreement was 0.42, indicating a fair to moderate agreement. We identified patient characteristics that may influence the accuracy of homecare worker estimates of depressive symptoms. IMPLICATIONS: Findings suggest that depression continues to be underdetected in medically ill homebound elderly patients. Ongoing training in depression screening methods, patient follow-up interviews, and appropriate referral would improve care of depressed elderly homecare patients.     

Children and aging: attitudes, differentiation ability, and quantity and quality of contact

The attitudes and age differentiation ability of forty-seven 3- to 5-year-old children toward pictures of older and younger people were assessed. In addition, cognitive performance on a seriation task as well as the quantity and quality of each child's contact with adults over 60 years of age were measured. Chi squares were performed by sex and age of stimulus photograph on the attitudinal questions. One of the chi squares reached significance on the age comparison and two on the sex comparison. In addition, sign tests were used to assess the direction of the trends on the questions, and both age and sex trends were significant at the .05 level with children being more likely to choose pictures of younger rather than older models and female rather than male models. Ability to correctly order pictures by age was significantly related (r = .53, p less than .001) to the seriation ordering task. Four of the 18 correlations between contact and attitudinal variables were significant and negative.

Perceived Control Over Aging-Related Declines: Adaptive Beliefs and Behaviors

ABSTRACT— The belief that people are in control of desired outcomes, including those associated with aging, is a hallmark of American culture. Nevertheless, older adults are less likely than the young to believe there are things that can be done to control aging-related declines in areas such as memory. Within age groups, individual differences in control beliefs are related to cognitive performance, health, and well-being. Mechanisms linking perceived control and positive outcomes include adaptive behaviors such as strategy use and physical activity. There is some evidence that control beliefs can be modified in later life, as illustrated in an intervention for fear of falling. Further work is needed to examine the antecedents of perceived control in later life and the implications of control beliefs in other aging-related domains.     

The perceived credibility of older adults as witnesses and its relation to ageism

In experiment 1, 267 undergraduates read a case summary and witness statement. Sex and age of the witness (49, 69, 79 or 89 years) were varied. Participants rated the witness's perceived convincingness, confidence, quality of observation, accuracy, honesty, competence, memory, suggestibility, and cognitive functioning. As well as an age effect for honesty, age by sex interactions were observed for several characteristics, particularly for comparisons of the 79-year-olds versus the 49-year-olds, and 89-year-olds versus the 49-year-olds. In experiment 2, 94 undergraduates read the same testimony given by a 79-year-old male or female witness, and completed the Fraboni Scale of Ageism and the Aging Semantic Differential. Participants who evidenced stronger aging stereotypes on these measures rated the witness less favorably than did participants who were less prejudiced. This experiment is the first to show a link between perceived credibility of older adults and ageist attitudes. Practical applications regarding how older witnesses are viewed by jurors, and the criminal justice system more generally, are discussed.
