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.

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.

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.

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.

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.

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.

[Allocation of cognitive resources during the simultaneous performance of cognitive and sensorimotor tasks].

We review research on the allocation of cognitive resources during the simultaneous performance of cognitive and sensorimotor tasks. From the developmental and clinical perspectives,we emphasize: (1) the distinction between the availability and the allocation of resources, (2) lifespan changes in relation to the environmental validity of sensorimotor functions, and (3) the potentials and limitations for an individuals' adaptations to multi-task constraints. These aspects can be operationalized within the framework of selection, optimization, and compensation (SOC).

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).

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) = .
