Exercise-induced changes in basal ganglia volume and cognition in older adults.

Physical activity has been demonstrated to diminish age-related brain volume shrinkage in several brain regions accompanied by a reduction of age-related decline in cognitive functions. Most studies investigated the impact of cardiovascular fitness or training. Other types of fitness or training are less well investigated. In addition, little is known about exercise effects on volume of the basal ganglia, which, however, are involved in motor activities and cognitive functioning. In the current study (1) we examined the relationships of individual cardiovascular and motor fitness levels with the volume of the basal ganglia (namely caudate, putamen, and globus pallidus) and selected cognitive functions (executive control, perceptual speed). (2) We investigated the effect of 12-month training interventions (cardiovascular and coordination training, control group stretching and relaxation) on the volume of the respective basal ganglia nuclei. Results revealed that motor fitness but not cardiovascular fitness was positively related with the volume of the putamen and the globus pallidus. Additionally, a moderating effect of the volume of the basal ganglia (as a whole, but also separately for putamen and globus pallidus) on the relationship between motor fitness and executive function was revealed. Coordination training increased caudate and globus pallidus volume. We provide evidence that coordinative exercise seems to be a favorable leisure activity for older adults that has the potential to improve volume of the basal ganglia.

[The meaning of work during early retirement]. / Die Bedeutung der Arbeit beim vorzeitigen Ausscheiden aus dem Arbeitsleben.

Since the mid-1990s, many German companies have used the part-time retirement scheme (Altersteilzeit) as an opportunity to release older workers. This was often consistent with the interests of the workers themselves. This paper explores whether workers who participate in this early retirement scheme would like to continue to work. A survey of all the workers in one company who participated in the part-time retirement scheme revealed that those already retired would more often like to continue working than employees who are still awaiting retirement. To a greater extent, early retirees would also like to return to work with shorter working hours or for a time-limited project. Results are explained with the affective forecasting bias that is based on the psychological decision theory and economic utility theory - the future utility of an action cannot be anticipated. The "reflective thinking" approach moreover invites the conclusion that the diverging interest of the two groups in continued employment may be due to the different stage of practical knowledge about the situation in (pre-)retirement.

[Activity, physical and psychological mobility in old age]. / Bewegung, körperliche und geistige Mobilität im Alter.

Old age and aging are accompanied by a number of physical and mental changes. However, these so-called age-dependent processes are not exclusively genetically determined or irreversible but can be partially delayed, prevented, or compensated and some can even be reversed. The goal of this article is to highlight the plasticity, or the "mobility", of physical and mental aging. We will point out in what respects an appropriate lifestyle or purposeful interventions can positively influence the reserve capacity of aging human beings and the aging process. Using the example of physical activity, we will illustrate how we can influence physiological development, cognitive performance, longevity, as well as the development and the occurrence of chronic diseases. Additionally, it is shown that cognitive development is malleable as well. It is facilitated or debilitated by behavior and activity-this covers not only cognitive but also physical activity. It is our particular concern to demonstrate the close interconnectedness of body and mind.

Seeds of wisdom: adolescents' knowledge and judgment about difficult life problems.

The present study examined adolescents' wisdom-related knowledge and judgment with a heterogeneous sample of 146 adolescents (ages 14-20 years) and a comparison sample of 58 young adults (ages 21-37 years). Participants responded to difficult and ill-defined life dilemmas; expert raters evaluated these responses along 5 wisdom criteria. Our findings confirmed that in contrast to adulthood, adolescence is a major period for normative age-graded development in knowledge about difficult life problems. Adolescents performed at lower levels than young adults but also demonstrated substantial age increments in performance. As expected, adolescents' performance varied as a function of criterion and gender. These results hold implications for research on adolescent development and for the development of wisdom-related knowledge and judgment.

Wisdom. A metaheuristic (pragmatic) to orchestrate mind and virtue toward excellence.

The primary focus of this article is on the presentation of wisdom research conducted under the heading of the Berlin wisdom paradigm. Informed by a cultural-historical analysis, wisdom in this paradigm is defined as an expert knowledge system concerning the fundamental pragmatics of life. These include knowledge and judgment about the meaning and conduct of life and the orchestration of human development toward excellence while attending conjointly to personal and collective well-being. Measurement includes think-aloud protocols concerning various problems of life associated with life planning, life management, and life review. Responses are evaluated with reference to a family of 5 criteria: rich factual and procedural knowledge, lifespan contextualism, relativism of values and life priorities, and recognition and management of uncertainty. A series of studies is reported that aim to describe, explain, and optimize wisdom. The authors conclude with a new theoretical perspective that characterizes wisdom as a cognitive and motivational metaheuristic (pragmatic) that organizes and orchestrates knowledge toward human excellence in mind and virtue, both individually and collectively.

Lifespan psychology: theory and application to intellectual functioning.

The focus of this review is on theory and research of lifespan (lifespan developmental) psychology. The theoretical analysis integrates evolutionary and ontogenetic perspectives on cultural and human development across several levels of analysis. Specific predictions are advanced dealing with the general architecture of lifespan ontogeny, including its directionality and age-differential allocation of developmental resources into the three major goals of developmental adaptation: growth, maintenance, and regulation of loss. Consistent with this general lifespan architecture, a meta-theory of development is outlined that is based on the orchestrated and adaptive interplay between three processes of behavioral regulation: selection, optimization, and compensation. Finally, these propositions and predictions about the general nature of lifespan development are examined and supported by empirical evidence on the development of cognition and intelligence across the life span.

Perspectives on socioemotional selectivity in late life: how personality and social context do (and do not) make a difference.

This research extends earlier cross-sectional findings suggesting that although social network sizes were smaller in very old age as compared to old age, the number of emotionally close relationships in the network did not distinguish age groups. In a representative sample of community dwelling and institutionalized adults, aged 70 to 104 years, we explored whether such indication of socioemotional selectivity was related to personality characteristics and family status. Extraversion, Openness to Experience, and Neuroticism as assessed by the NEO-PI were related to overall network size but unrelated to the average emotional closeness of social partners in the network (i.e., our indicator of socioemotional selectivity). Family status, in contrast, was related to average emotional closeness to network members. Moreover, family status moderates the relationship between average emotional closeness to network members and feelings of social embeddedness. Findings suggest a stronger influence of contextual rather than personality factors on social functioning in late life.

People nominated as wise: a comparative study of wisdom-related knowledge.

This study examined whether our conception of wisdom has a psychological bias, by focusing on a group of distinguished individuals nominated as being wise. The comparison groups included older clinical psychologists and highly educated old and young control groups. Wisdom-related knowledge was assessed by 2 tasks and evaluated with a set of 5 wisdom criteria. First, old wisdom nominees performed as well as clinical psychologists who in past research had shown the highest levels of performance. Second, wisdom nominees excelled in the task of existential life management and the criterion of value relativism. Third, up to age 80, older adults performed as well as younger adults. If there is a psychological bias to our conception of wisdom, this does not prevent nonpsychologists from being among the top performers.

Occupational settings facilitating wisdom-related knowledge: the sample case of clinical psychologists.

Wisdom can be defined as expert knowledge in the fundamental pragmatics of life. Examined here is whether clinical practice may facilitate access to and acquisition of such knowledge. Spontaneous think-aloud responses to 2 wisdom-related dilemmas from young (M = 32 years) and older (M = 70 years) clinicians were compared with responses obtained from other professionals. Raters judged clinicians' responses as higher on 5 criteria of wisdom: factual knowledge, procedural knowledge, life-span contextualism, value relativism, and management of uncertainty. Contrary to most studies of cognitive aging, young and older adults did not differ. Rather, each age-cohort group received highest ratings when responding to a life dilemma matched to their own life phase. Discussed is the application of a wisdom framework to assessing therapeutic treatment goals and therapist interventions as well as global changes in client's beliefs during therapy.

Wisdom-related knowledge in a life review task: age differences and the role of professional specialization.

The study adopts life review as an avenue to access wisdom-related knowledge and examines the contribution of age and type of professional specialization to individual differences in wisdom-related knowledge. Women from 2 age groups/cohorts (young, M = 32 years; old, M = 71 years) and different professional specializations (human services vs. nonhuman services) were asked to think aloud about the life review of a fictitious woman who was either young or old. Verbal protocols were scored on 5 wisdom-related criteria: factual and procedural knowledge about life, life-span contextualism, relativism of values, recognition, and management of uncertainty. Three major findings emerged. First, human-services professionals outperformed the control group. Second, old adults performed as well as young adults. Third, for older adults wisdom-related performance was enhanced by the match between their own age and the age of the fictitious character.
