Lifespan changes in multi-tasking: concurrent walking and memory search in children, young, and older adults.

We investigated dual-task performance of cognitive (semantic fluency) and sensorimotor tasks (walking) in 120 children and adults from four age groups (9-year olds, M=9.52 years; 11-year olds, M=11.51 years; young adults, M=25.

Developmental emergence and functionality of Sehnsucht (life longings): the sample case of involuntary childlessness in middle-aged women.

Sehnsucht (life longings), the intense desire for optimal (utopian) states of life that are remote or unattainable, was recently introduced into life-span psychology as a concept of self-regulation (P. B. Baltes, 2008; S.

Age differences between children and young adults in the dynamics of dual-task prioritization: body (balance) versus mind (memory).

Task prioritization can lead to trade-off patterns in dual-task situations. The authors compared dual-task performances in 9- and 11-year-old children and young adults performing a cognitive task and a motor task concurrently. The motor task required balancing on an ankle-disc board.

The Fascination of Wisdom: Its Nature, Ontogeny, and Function.

Wisdom has intrigued both scholars and laypersons since antiquity. On the one hand, its seemingly ethereal yet obvious qualities are timeless and universal. On the other hand, these same qualities are evolving and responsive to historical and cultural change.

Desired lifetime and end-of-life desires across adulthood from 20 to 90: a dual-source information model.

How long do people want to live, and how does scientific research on aging affect such desires? A dual-source information model proposes that aging expectations and desires are informed differently by two sources: personal experiences on the one hand, and scientific and societal influences on the other. Two studies with independent German national samples explored desires regarding length of life and end of life among adults between the ages of 20 and 90. FINDINGS ARE: First, desired lifetime is consistent at around 85 years with few age differences.

Reduced negativity effect in older adults' memory for emotional pictures: the heterogeneity-homogeneity list paradigm.

Using the heterogeneity-homogeneity list paradigm, the authors investigated 48 young adults' (20-30 years) and 48 older adults' (65-75 years) recognition memory for emotional pictures. The authors obtained no evidence for a positivity bias in older adults' memory: Age differences were primarily driven by older adults' diminished ability to remember negative pictures. The authors further found a strong effect of list types: Pictures, particularly neutral ones, were better recognized in homogeneous (blocked) lists than in heterogeneous (mixed) ones.

Toward a developmental psychology of Sehnsucht (life longings): the optimal (utopian) life.

The topic of an optimal or utopian life has received much attention across the humanities and the arts but not in psychology. The German concept of Sehnsucht captures individual and collective thoughts and feelings about one's optimal or utopian life. Sehnsucht (life longings; LLs) is defined as an intense desire for alternative states and realizations of life.

Using the concept of wisdom to enhance the expression of wisdom knowledge: not the philosopher's dream but differential effects of developmental preparedness.

In this study, the authors explored whether wisdom-related performance could be enhanced by an instruction referring to the abstract concept of wisdom ("try to give a wise response"). The authors used three levels of activation of the concept of wisdom as well as intelligence-activation and control conditions in a heterogeneous sample of three age groups (N = 318). Results showed no general effect of the wisdom-concept instructions but did show an aptitude (resource) treatment interaction: Participants high in preparedness resources associated with wisdom exhibited some gains, whereas the performance of resource-low participants actually declined after the instruction.

Developmental changes in personal goal orientation from young to late adulthood: from striving for gains to maintenance and prevention of losses.

Using a multimethod approach, the authors conducted 4 studies to test life span hypotheses about goal orientations across adulthood. Confirming expectations, in Studies 1 and 2 younger adults reported a primary growth orientation in their goals, whereas older adults reported a stronger orientation toward maintenance and loss prevention. Orientation toward prevention of loss correlated negatively with well-being in younger adults.

A systemic-wholistic approach to differential aging: longitudinal findings from the Berlin Aging Study.

Wholistic perspectives on differential change focus on multiple-indicator information at a person level. They supplement the modeling of average trajectories at a variable level. The authors extended cross-sectional work in the Berlin Aging Study (J.

Basic forms of cognitive plasticity extended into the oldest-old: retest learning, age, and cognitive functioning.

To address the question of whether cognitive plasticity varies by age and level of cognitive functioning in the older population, the authors used a self-guided retest paradigm to assess the basic forms of plasticity of 34 young-olds (M=74.4 years, range=70-79) and 34 oldest-olds (M=84.0 years, range=80-91), with half in each age group screened for high or low (midrange) level of cognitive functioning.

No aging bias favoring memory for positive material: evidence from a heterogeneity-homogeneity list paradigm using emotionally toned words.

Some authors argue for a memory advantage of older adults for positively toned material. To investigate the contribution of selective processing to a positivity effect, the authors investigated young (n = 72, aged 18 to 31) and older (n = 72, aged 64 to 75) adults' memory for emotionally toned words using a multitrial paradigm that compares performance for heterogeneous (mixed valence) and homogeneous (single valence) lists. Regarding the age comparison, there was no evidence for an aging bias favoring positive material.

Adaptive task prioritization in aging: selective resource allocation to postural control is preserved in Alzheimer disease.

Objective: With age, the performance of multiple tasks decreases, a pattern exaggerated in Alzheimer disease (AD). At the same time, recent research, based on adaptive theories of healthy aging, indicates a preference of older adults to allocate resources toward tasks of higher immediate value (e.g.

Managing life through personal goals: intergoal facilitation and intensity of goal pursuit in younger and older adulthood.

Two studies varying in design (cross-sectional and longitudinal) and methods (questionnaires, diaries, and objective information) support the notion that personal goals are among the phenomena that show positive development throughout adulthood: Older adults (M = 64 years) reported more mutual facilitation among their personal goals and were more engaged in goal pursuit than were younger adults (M = 25 years). Results were robust when age-group differences in education and disposable time were controlled for, and they also emerged in a context where younger and older participants had one goal in common, namely, to start regular physical exercise. Mediational analyses showed that the older adults' higher intensity of goal pursuit was partly mediated by their higher level of intergoal facilitation.

Wisdom-related knowledge: affective, motivational, and interpersonal correlates.

This study investigated the connection between wisdom as a body of expert knowledge about the meaning and conduct of life and indicators of affective, motivational, and interpersonal functioning. Structural equation analyses showed that individuals higher on wisdom-related knowledge reported (a) higher affective involvement combined with lower negative and pleasant feelings, (b) a value orientation that focused conjointly on other-enhancing values and personal growth combined with a lesser tendency toward values revolving around a pleasurable life, and (c) a preference for cooperative conflict management strategies combined with a lower tendency to adopt submissive, avoidant, or dominant strategies. These findings corroborate the theoretical notion that wisdom involves affective modulation and complexity rather than the predominant seeking of pleasure and also a joint motivational commitment to developing the potential of oneself and that of others.

Transformations in the couplings among intellectual abilities and constituent cognitive processes across the life span.

Two-component theories of intellectual development over the life span postulate that fluid abilities develop earlier during child development and decline earlier during aging than crystallized abilities do, and that fluid abilities support or constrain the acquisition and expression of crystallized abilities. Thus, maturation and senescence compress the structure of intelligence by imposing age-specific constraints upon its constituent processes. Hence, the couplings among different intellectual abilities and cognitive processes are expected to be strong in childhood and old age.

The fate of cognition in very old age: six-year longitudinal findings in the Berlin Aging Study (BASE).

The authors report full-information longitudinal age gradients in 4 intellectual abilities on the basis of 6-year longitudinal changes in 132 individuals (mean age at T1 = 78.27, age range = 70-100) from the Berlin Aging Study. Relative to the cross-sectional parent sample (N = 516, mean age at T1 = 84.

Plasticity of memory for new learning in very old age: a story of major loss?

Longitudinal survivors of the Berlin Aging Study (N = 96, mean age = 84 years, range 75-101 years) were instructed and trained in a mnemonic skill to examine plasticity of episodic memory performance in very old age. Performance gains after mnemonic instruction were modest, and most individuals were unable to further enhance their performance during 4 sessions of mnemonic practice. Whereas the proportion of variance explained by measures from the broad fluid-ability domain (e.

New frontiers in the future of aging: from successful aging of the young old to the dilemmas of the fourth age.

We review research findings on the oldest old that demonstrate that the fourth age entails a level of biocultural incompleteness, vulnerability and unpredictability that is distinct from the positive views of the third age (young old). The oldest old are at the limits of their functional capacity and science and social policy are constrained in terms of intervention. New theoretical and practical endeavors are required to deal with the challenges of increased numbers of the oldest old and the associated prevalence of frailty and forms of psychological mortality (e.

Longitudinal selectivity in aging populations: separating mortality-associated versus experimental components in the Berlin Aging Study (BASE).

The authors examined 3.7-year selectivity in the Berlin Aging Study by comparing the T1 parent sample (N = 516) with the T3 sample (N = 206). Selectivity was partitioned into a mortality-associated component, reflecting the degree to which individuals still alive at T3 (T3 survivors, N = 313) differ from the T1 parent sample (N = 516) from which they originated, and an experimental component, reflecting the degree to which the T3 sample (N = 206) differed from T3 survivors (N = 313).

Two-wave longitudinal findings from the Berlin aging study: introduction to a collection of articles.

We provide background information for a collection of articles that describe two-wave longitudinal findings derived from the first intensive follow-up of participants of the Berlin Aging Study (BASE). Multidisciplinary data were collected during 1995-1996 from 206 survivors approximately 4 years after baseline assessment (1990-1993). The strengths of the initial BASE design, in terms of a focus on very old age, multidisciplinary intensive assessment, and an examination of selectivity issues, were maintained in this longitudinal extension of the study.

The adaptiveness of selection, optimization, and compensation as strategies of life management: evidence from a preference study on proverbs.

Proverbs were used to examine whether laypeople's conceptions of or preferences for life-management strategies are consistent with the model of selection, optimization, and compensation (SOC model). The SOC model posits that there are three fundamental processes of life management: selection, optimization, and compensation. In two studies (N = 64; N = 131), young (19-32 years) and older adults (59-85 years) were asked to match proverbs to sentence stems indicative of life-management situations.

Life-management strategies of selection, optimization, and compensation: measurement by self-report and construct validity.

The authors examined the usefulness of a self-report measure for elective selection, loss-based selection. optimization, and compensation (SOC) as strategies of life management. The expected 4-factor solution was obtained in 2 independent samples (N = 218, 14-87 years; N = 181, 18-89 years) exhibiting high retest stability across 4 weeks (r(tt) = .

Cognitive training research on fluid intelligence in old age: what can older adults achieve by themselves?

Cognitive research on the plasticity of fluid intelligence has demonstrated that older adults benefit markedly from guided practice in cognitive skills and problem-solving strategies. We examined to what degree older adults are capable by themselves of achieving similar practice gains, focusing on the fluid ability of figural relations. A sample of 72 healthy older adults was assigned randomly to three conditions: control, tutor-guided training, self-guided training.

Reserve capacity of the elderly in aging-sensitive tests of fluid intelligence: replication and extension.

Fluid intelligence belongs to that cluster of intellectual abilities evincing aging loss. To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence.
