Cognitive plasticity in normal and pathological aging

The main goal of the present study is to examine to what extent age and cognitive impairment contribute to learning performance (cognitive plasticity, cognitive modifiability, or learning potential). To address this question, participants coming from four studies (Longitudinal Study of Active Aging, age range, 55–75 years, N = 458; Longitudinal Study in the very old [90+], age range, 90–102, N = 188, and Cognitive Plasticity within the Course of Cognitive Impairment, 97 “Normal”, 57 mild cognitive impairment [MCI], and 98 Alzheimer’s disease [AD] patients) were examined through a measure of verbal learning (developed from Rey). The results show that all age, MCI, and AD groups learned across the five learning trials of that test, but significant differences were found due to age, pathology, and education. The effects of pathology (MCI and AD) can be expressed in a metric of “years of normal decline by age”; specifically, being MCI means suffering an impairment in performance that is equivalent to the decline of a normal individual during 15 years, whereas the impact of AD is equivalent to 22.7 years. Likewise, the improvement associated with about 5 years of education is equivalent to about 1 year less of normal aging. Also, the two pathological groups significantly differed from “normal” groups in the delayed trial of the test. The most dramatic difference is that between the “normal” group and the AD patients, which shows relatively poorer performance for the AD group in the delayed trial than in the first learning trial. The potential role of this unique effect for quick detection purposes of AD is assessed (in the 75–89 years age range, sensitivity and specificity equal 0.813 and 0.917, respectively).

Productivity in Old Age

It is commonly assumed that older adults are “unproductive” as soon as they retire and begin receiving a pension from the social security system, as occurs in most European countries. This article deals with the concept of unpaid work and social productivity, on the basis of data collected in the base line of the Estudio Longitudinal sobre Envejecimiento Activo (ELEA; Longitudinal Study of Active Aging), exploring the extent to which Spanish older adults (aged 55 to 75) report being involved in productive activities. First, the data are examined by age, gender, and working status; and second, under moderate-cost assumptions, the unpaid contribution to society of older people is calculated, in terms of Euros. The results are discussed in the context of other general studies about unpaid productive activities in old age; it is concluded that our sample is characterized by a focus on productive activity related to care for other adults and children and their estimated contribution in unpaid activities expresses the importance of older persons as social capital.

Effects of University Programs for Older Adults: Changes in Cultural and Group Stereotype, Self-Perception of Aging, and Emotional Balance

University Programs for Older Adults (Programas Universitarios para Adultos Mayores or PUMAs) have been developed throughout the world as an outcome of two worldwide policies: Life Long Learning (LLL) and Active Aging as a priority direction (UN, 2002). According to these policies, older persons should become full participants in the development process of a society, sharing in its benefits, while policies and actions should promote a positive view of aging. The present paper sets out to report some of the results from the evaluation of four PUMAs offered in 2009–2010 at four Universities: Autónoma University of Madrid (Spain), Autónoma University of Mexico (Mexico), Catholic University (Chile), and La Habana University (Cuba). With this purpose, a study with quasiexperimental design and nonequivalent control group was carried out. In total, 313 students (75% women, age range 50–87) on these four PUMAs and 190 controls (77% female, age range 50–91) participated in this evaluation study. Pre- and postexperimental and control comparisons results yielded significant differences in the expected direction: those people attending PUMAs significantly improved their self-perception of aging and group stereotypes, as well as significantly reduced their negative affect, and improving their emotional balance. At the same time, their perception of cultural age stereotypes became more negative. The results are discussed from the point of view of the II International Plan of Action on Aging objectives: the reduction of negative stereotypes and the promotion of the role of PUMAs in active aging.

The Semantic Network of Aging Well

“Aging well” is a common expression used by lay people as synonymous with a set of verbal labels emerging from scientific literature attributed to a positive trajectory of aging—healthy, successful, competent, optimal, vital, active, or productive aging. These terms with tightly semantic relations conform to a semantic network. This chapter provides a historical overview of the different terminology, followed by a review of the definitions used by researchers as well as an assessment of the extent to which older adults are aging well in different studies. Second, the lay cross-cultural concept of aging well is described. This provides a useful backdrop for dealing with potential problems and issues in operationalizing definitions of aging well (confounding outcomes and predictors, using objective and/or subjective indicators, and to what extent different definitions are required at different ages). Finally, the issue of to what extent the different labels of aging well have different nuances in their meanings is assessed.

Actividades cognitivas y funcionamiento cognitivo en personas muy mayores

INTRODUCTION The aim of this study was to analyse whether the activity is a protective factor of intellectual decline, and specifically to examine whether intellectual activity versus other activities, is a better predictor for the maintenance of cognitive functioning in a group of people over 90 years, independent in basic daily living activities and having preserved cognitive capacity. MATERIAL AND METHODS This sample was selected from a bio-psycho-social longitudinal study of independent persons 90 and over. This is a longitudinal study involving 188 people, 67 males and 121 females. Measurements were taken of cognitive functioning and level of activity and repeated between 6 and 14 months; inferential analysis was performed at baseline and follow-up. RESULTS At base-line, there is a strong association between the level of activity and performance. Also, and most important, intellectual activities at baseline predict cognitive functioning at follow-up. According to our results, intellectual activities and the maintenance of cognitive functioning are associated with the absence of cognitive impairment in the very elderly. CONCLUSIONS This has important implications for the scientific community in finding a predictive index and strategies, but also for the individual to identify factors of change on which to act to reduce problems associated with aging.

Is older adult care mediated by caregivers' cultural stereotypes? The role of competence and warmth attribution.

Purpose The purpose of this study is to examine, from the stereotype content model (SCM) perspective, the role of the competence and warmth stereotypes of older adults held by professional caregivers. Methods A quasi-experimental design, ex post facto with observational analyses, was used in this study. The cultural view on competence and warmth was assessed in 100 caregivers working in a set of six residential geriatric care units (three of them organized following a person-centered care approach and the other three providing standard geriatric care). In order to assess caregivers’ cultural stereotypical views, the SCM questionnaire was administered. To evaluate the role of caregivers’ cultural stereotypes in their professional performance as well as in older adult functioning, two observational scales from the Sistema de Evaluación de Residencias de Ancianos (assessment system for older adults residences)-RS (staff functioning and residents’ functioning) were applied. Results Caregivers’ cultural views of older adults (compared to young people) are characterized by low competence and high warmth, replicating the data obtained elsewhere from the SCM. Most importantly, the person-centered units predict better staff performance and better resident functioning than standard units. Moreover, cultural stereotyping of older adult competence moderates the effects of staff performance on resident functioning, in line with the findings of previous research. Conclusion Our results underline the influence of caregivers’ cultural stereotypes on the type of care, as well as on their professional behaviors and on older adult functioning. Caregivers’ cultural stereotypes could be considered as a central issue in older adult care since they mediate the triangle of care: caregivers/older adults/type of care; therefore, much more attention should be paid to this psychosocial care component.

Cultural stereotypes in care contexts

Introduction The main goal of the present study was to examine the stereotype content model (SCM) assumption for universality and to test whether the mediating role of cultural views about older adult caregivers is maintained in other health care contexts. Methods One hundred and sixty professionals and volunteers who worked with older adults in day care centers (DCCs) and senior citizen centers (SCCs) and 1,151 participants from a representative sample of the Spanish population were examined using the SCM questionnaire; older adult and personnel functioning were assessed through an observation procedure with two subscales of the Evaluation Scale from the Sistema de Evaluación de Residencias de Ancianos. Results The results showed that the context does not seem to influence the cultural views about older adults held by caregivers. All results support the cultural stereotype pattern in which members of the older adult group are viewed with high warmth (HW) and low competence (LC) as posited by the SCM model. With respect to the mediation of cultural stereotypes on caregivers/older adult functioning, this has not been supported in this study. Neither cultural views of warmth (predicted by the SCM) nor views of competence (from our previous studies) influence either caregiver functional behaviors or older adult functioning. Conclusion Two post hoc hypotheses can be inferred: 1) there is more variability in competence and warmth in DCCs and SCCs and 2) although we did not find significant differences in the pattern of competence and warmth in perceived cultural stereotypes about older adults, more healthy environments could reduce the influence of cognitive views on behavior.
