Stability and change in longitudinal water-level task performance.

Three longitudinal samples of children (N?=?481), 8 to 16 years old, were assessed 3 times at yearly intervals on 8 water-level items. The within-child change in task performance over age is viewed as a stochastic process of the child changing or remaining in 1 of 3 latent (strategy) states: (a) bottom-parallel responders, (b) random responders, or (c) accurate responders. A random-effects binomial mixture distribution is used to model performance at each age. Change over age is gauged by a stochastic transition model. Although there was improvement in task performance over age, the more general finding is that strategy stability, not change, is most typical.

Longitudinal change in cognitive performance among individuals with mild cognitive impairment.

The authors used mixed-effects growth models to examine longitudinal change in neuropsychological performance over a 4-year period among 197 individuals who were either normal or had mild cognitive impairment (MCI) at baseline. At follow-up, the participants were divided into 4 groups: (a) controls: participants who were normal at both baseline and follow-up (n = 33), (b) stables: participants with MCI whose Clinical Dementia Rating-Sum of Boxes (CDR-SB) score did not differ between the first and last evaluations (n = 22), (c) decliners: participants with MCI whose CDR-SB score declined between the first and last evaluations (n = 95), and (d) converters: participants who received a clinical diagnosis of Alzheimer's disease during the follow-up period (n = 47). Only the Episodic Memory factor showed a significantly greater rate of decline over the follow-up period among the converters. Two other factors were significantly lower in converters at baseline in comparison with other groups (the executive function factor and the general knowledge factor), but the rate of decline over time did not differ. Individuals with an APOE ε4 allele scored lower on the episodic memory and executive function factors at baseline. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Moral and social reasoning and perspective taking in later life: A longitudinal study.

In this study 27 older adults (ages 64–80) and 23 middle-aged adults (ages 35–54) were tested for moral stage, integrative complexity of social reasoning, and perspective-taking levels twice over a 4 year period. Moral reasoning stage levels did not change over time for either age group. Older adults, but not the middle-aged, showed a significant decline over time in level of moral perspective taking. Complexity of reasoning about several interpersonal social issues declined modestly in both age groups. More social-cognitive support, a higher education level, and better self-reported health were all found to be protective factors in forestalling declines in mature adults' sociocognitive reasoning, consistent with other research on cognitive measures in later life.

Supportive relationships in later life.

Adopted a multidimensional approach to the study of the social support convoys of older adults. We distinguished between age and gender differences in 4 specific dimensions of the social support convoy: (a) existence vs functioning of relationships in the convoy, (b) kinds of relationships (i.e., those with children, siblings, friends), (c) types of social support (i.e., emotional support, respect, health support), and (d) receipt vs provision of support. Ss were 718 adults. We found that older people received less support (i.e., emotional and health support) in the absence of sibling relationships. Otherwise, the effects of aging had more to do with what the older person contributed to the convoy than with what he or she received. Women had better social support resources than men, particularly within friendships. We found no evidence, however, that women's social support advantage counterbalanced the effects of aging on the convoy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Variability and stability in cognitive abilities are largely genetic later in life

Radiographic cephalometry has been used for the assessment of the effects of mandibular rotation and of posterior growth displacement of the temporomandibular joint on the development of the face and on overjet in 43 patients with complete unilateral cleft lip and palate between the ages of 10 and 15 years. Rotation acted mainly on vertical facial measurements and on the position of the lower jaw. The degree of posterior displacement of the temporomandibular joint exerted an influence on the position of the mandible, on the difference between the functional length of the upper and lower jaw, and on the occlusion of incisors. The direction of growth of the mandible as a whole represented the result of a combination of changes produced by the rotation of the jaw and by the degree of posterior displacement of the temporomandibular joint. The most favourable conditions for development were a combination of the neutral type of rotation with a more pronounced posterior displacement of the temporomandibular joint.     

Foreword: Psychotherapy in later life.

This special topic issue (psychotherapy in later life) is an outcome of our increasing interest and involvement in recent years with gerontology, particularly with psychotherapy for the elderly. It reflects the new and current social, economic and political significance of this population in our society and within the helping professions. This issue encompasses a broad sampling of the present state of the art represented by contributions from recognized authorities and dedicated workers in gerontology at academic, clinical, private and government centers serving the elderly throughout the United States. The currently broad spectrum of psychotherapeutic theory, research, and practice focusing on the elderly is demonstrated in our contributors' articles. Included are works concerned with historical, psychosocial aspects, individual and group therapy, sexism and sex differences, possibilities and limitations of applying various psychotherapeutic approaches such as behavioral, environmental, psychoanalytic and cognitive. Attention is paid to special needs of the frail and dependent elderly as well as to the more vigorous and autonomous older person coping, with varying degrees of independence, in non-institutional settings. No single publication can deal effectively with the enormity of issues confronting the elderly and the range of gerotherapies. If we have opened new doors for continued progress, and stimulated more reflection and action on behalf of this population, we shall feel rewarded by having laid the seeds for a new special topic issue in the approaching decade by future investigators.

Physical maturation rate and cognitive performance in early adolescence: A longitudinal examination.

A longitudinal experiment examined (1) the development of the relationship between physical maturation rate and cognitive performance as children reach adolescence and (2) the specific components of cognitive processing that are most closely linked to physical maturation rate. 78 3rd-grade girls and 67 5th-grade boys were examined prepubertally on a battery of cognitive ability and perceptual asymmetry measures (including the PPVT) and reexamined 2 yrs later when secondary sex characteristics could be evaluated as a measure of pubertal status. At that time, extreme groups of 10 early and 10 late maturers for each sex were selected for examination on a more detailed battery (including the WISC—R Coding and Block Design subtests and the Stroop Color-Word test) designed to assess specific components of cognitive processing. Although there were no maturation-related differences in performance on the cognitive-ability tasks, differences were detected on the cognitive-process tasks: Early and late maturers of both sexes exhibited differences in their use of visual information, phonemic perception, and presence of a recency effect in the serial-memory task.

Goal instability and later life adjustment.

A series of analyses on the goal instability personality construct, as measured by the Goal Instability Scale (GIS [S. B. Robbins and M. J. Patton; see PA, Vol 72:16362]), was conducted to establish the construct validity of goal instability as it relates to older adults. This construct was derived from Heinz Kohut's psychology of the self. The sample consisted of a total of 157 voluntary early retirees representing a cross section of worker types from a manufacturing industry. In the first analysis, a series of confirmatory factor analyses supported the hypothesis that the 10-item GIS measures a unitary construct. In the second analysis, GIS was found to be similar across age groups. These findings enhance the conceptual clarity of the goal instability construct and its relevance with regard to older adults. Goal instability may represent 1 negative aspect of a quest for self-continuity. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-efficacy beliefs and change in cognitive performance: MacArthur studies on Successful Aging.

Data from a cohort of relatively high functioning, older men and women were used to test the hypothesis that stronger self-efficacy beliefs predict better maintenance of cognitive performance. Structural equation modeling revealed that stronger baseline instrumental efficacy beliefs predicted better verbal memory performance at follow-up among men but not among women, controlling for baseline verbal memory score and sociodemographic and health status characteristics. For both men and women there were no significant associations between either type of self-efficacy beliefs and measures of nonverbal memory, abstraction, or spatial ability. Consistent with previous research showing relationships between baseline cognitive performance and change in self-efficacy beliefs, better abstraction ability was also predictive of increases in instrumental efficacy beliefs among the men.

Neighborhood deterioration and self-rated health in later life.

This study examined the relationship between the physical living environment and self-rated health in later life. It is hypothesized that older adults who reside in deteriorated neighborhoods will report more physical health problems than elderly people who live in better physical environments. However, it is further predicted that these effects will only emerge in the most dilapidated living conditions. Data from a nationwide survey of older adults provide support for this complex nonlinear relationship. Further analyses reveal that part of the effect can be attributed to friendship strains that arise in deteriorated neighborhood environments.

Subjective memory complaints, psychological distress, and longitudinal change in objective memory performance.

Between 1992 and 1993, the Memory Function Questionnaire General Frequency of Forgetting Scale (MFQ-GEN), the Symptom Checklist-90—Revised General Severity Index (GSI), and Mayo Cognitive Factor Scales Learning and Retention (MCFS-LRN and MCFS-RET) current and change scores were obtained for 294 of 397 (74% ) participants, ages 55–97 years, originally assessed in a 1988–1990 normative study. In multiple regression modeling, the GSI and MCFS-LRN current score contributed 20% and 3%, respectively, to MFQ-GEN variance. Thus, emotional status was a better predictor of subjective memory ratings than either absolute objective memory performance or objective longitudinal memory change. Persons who developed cognitive impairment over the longitudinal interval reported greater memory problems, but memory complaints had little sensitivity in identifying these persons. In an approximate census sample of these older people, minor memory problems were reported to be frequent but not serious. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychosocial outcomes in later life: A multivariate model.

A conceptual model was developed to identify developmental self-regulatory pathways to optimal psychosocial outcomes in adulthood. The model delineates influences among age, possible selves, developmental processes (i.e., coping, control), and well-being. Results showed age effects on all constructs except selective control. Three consistently common predictors of well-being (i.e., goal pursuit, goal adjustment, and optimization) emerged. The effects of age on well-being were differentially mediated by developmental processes. Specifically, negative age-related changes in offensive processes (i.e., goal attainment) were offset by positive influences of defensive processes (i.e., goal adjustment), which had the net effect of preserving well-being. The model demonstrates a more optimistic pattern of aging in which gains offset losses leading to positive outcomes and highlights the importance of examining both independent and combined influences of age, self, and developmental processes on psychosocial outcomes.

Short-term β-amyloid vaccinations do not improve cognitive performance in cognitively impaired APP+PS1 mice.

Prior work demonstrated that β-amyloid (Aβ) immunotherapy for 8 months prevented cognitive impairment in 16-month-old APP+PS1 transgenic mice. In the present study, 4 immunizations administered biweekly to cognitively impaired 16-month-old transgenic mice could not reverse deficits in working memory or reference memory in the radial arm water maze or in visual platform recognition, possibly because of inadequate antibody exposure. Nontransgenic mice showed cognitive savings between the 16- and 18-month test periods, but the transgenic groups did not. These results suggest that a longer period of active immunotherapy, or passive immunization, may be required to provide sufficient antibody titers to improve cognition in older transgenic mice. Aβ-based immunotherapy for Alzheimer's disease will likely be more successful prophylactically than therapeutically. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Motivation in later life: Personal projects and well-being.

"Personal projects," as defined by B. R. Little (1983), were elicited from 600 community residents aged 70+, representing a broad range of health and illness. Factor analysis revealed 6 types of personal projects: activities of daily living, active recreation, other-oriented activities, intellectual activities, home planning, and spiritual/moral activities. Background factors and health were shown to affect the number and type of projects reported. Most indices of personal projects were associated with positive affect and valuation of life. Only 1 was associated with depression. This confirms the differential association of personal projects to positive but not negative affect. Personal projects are seen as part of an open motivational system in which social position, cognitive ability, health, and positive mental health are mutually interacting members.

Individual differences in cross-sectional and 3-year longitudinal memory performance across the adult life span.

Reports individual differences analyses of performance on list and prose memory tasks for 250 men and 258 women (aged 55–84 yrs). Being retested, higher reasoning and vocabulary scores, and female gender predicted better prose recall and list recognition performance. For list recall, retest status, age, years of schooling, and gender, as well as reasoning and vocabulary, were reliable independent predictors. After 3 yrs, 106 men and 121 women returned for a retest. Analysis of individual differences in 3-yr performance indicated that, once Time 1 performance had been partialed, individual change could be predicted by age or reasoning, but neither variable uniquely accounted for change. Analysis of data of individuals who experienced considerable decline or improvement in 3-yr scores indicated that decline was consistently associated with advanced age. Ramifications for theoretical models in memory research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Children's sleep and cognitive performance: A cross-domain analysis of change over time.

Relations between changes in children's cognitive performance and changes in sleep problems were examined over a 3-year period, and family socioeconomic status, child race/ethnicity, and gender were assessed as moderators of these associations. Participants were 250 second- and third-grade (8–9 years old at Time 1) boys and girls. At each assessment, children's cognitive performance (Verbal Comprehension, Decision Speed) was measured using the Woodcock-Johnson III Tests of Cognitive Abilities, and sleep problems (Sleepiness, Sleep/Wake Problems) were collected via self-report. Individual growth models revealed that children who reported increases in Sleepiness exhibited little growth in Verbal Comprehension over time compared with their peers who reported decreases in Sleepiness, resulting in a nearly 11-point cognitive deficit by the end of the study. These associations were not found for Sleep/Wake Problems or Decision Speed. Child race/ethnicity and gender moderated these associations, with Sleepiness serving as a vulnerability factor for poor cognitive outcomes, especially among African American children and girls. Differences in cognitive performance for children with high and low Sleepiness trajectories ranged from 16 to 19 points for African American children and from 11 to 19 points for girls. Results build substantially on existing literature examining associations between sleep and cognitive functioning in children and are the first to demonstrate that children's sleep trajectories over 3 waves were associated with changes in their cognitive performance over time.

Personality and risk of cognitive impairment 25 years later.

The authors examined the relationship between personality and cognitive impairment in 4,039 members of the Swedish Twin Registry. Neuroticism and extraversion scores were collected in 1973 at midlife, and cognitive impairment was assessed in the same group 25 years later. Data were analyzed with case-control and co-twin control designs. Greater neuroticism was associated with higher risk of cognitive impairment in the results from case-control, but not from co-twin, analyses. Compared with both extraversion and introversion, moderate extraversion was associated with lower risk of cognitive impairment in both case-control and co-twin designs, as was the combination of high neuroticism and low extraversion. Findings are discussed in the context of theories related to personality, psychological distress, arousal, and cognitive function. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

From infant to child: The dynamics of cognitive change in the second year of life.

The authors review several key areas of early cognitive development in which an abrupt shift in ability at the end of the second year of life has been traditionally assumed. These areas include deferred imitation, self-recognition, language, and categorization. Contrary to much conventional theorizing, the evidence shows robust continuities in all domains of early cognitive development. Where there is evidence of a reorganization of behavior that makes a new level of performance possible, dynamic-systems analyses indicate that even these may be driven by underlying processes that are continuous. Although there remain significant definitional and methodological issues to be resolved, the outcome of this review augers well for newer models in which cognitive development is viewed as a continuous, dynamic process.
