Future Time Perspective: Time Horizons and Beyond.
Authors: Liao HW, Carstensen LL Abstract The articles in the present volume enhance the understanding of the role of perceived time in human development. Together, they point to the multifaceted nature of perceived future time and the associations different aspects of time have with goals, preferences, and well-being. Specifically, the articles showcase antecedents and consequences of perceived time left in life, consider ways to optimize measurement of future time horizons, and advance novel questions about the neural correlates of domain-specific aspects of subjective time. Findings are considered within the fram...

Daily Activity Abilities in MCI, Alzheimer's Disease, and Healthy Controls.
Authors: Avila J, Flowers A, Scott TM, Quilici J, Apostolova LG, Woo E, Ringman J, Razani J Abstract Mild cognitive impairment (MCI) is a risk state for dementia. The present study assessed daily functioning in MCI individuals (amnestic [aMCI] and nonamnestic [naMCI]) relative to those with Alzheimer's disease (AD) and healthy controls (NC). Twenty AD participants, 14 aMCI, 12 naMCI, and 30 healthy controls were administered the Direct Assessment of Functional Status (DAFS). The AD group performed poorer than all groups on all DAFS subscales. The aMCI group performed poorer than controls on the shopping subtests, w...

The Effects of Suffering in Chronically Ill Older Adults on the Health and Well-Being of Family Members Involved in Their Care: The Role of Emotion-Related Processes.
Authors: Monin JK, Schulz R Abstract A large literature shows that caregivers of chronically ill older adults have a higher risk for impaired health and decreased longevity. In this paper we review research that addresses pathways through which family members experience negative health consequences from exposure to a partner's suffering. We first provide a conceptualization of suffering and describe how it can be measured, then review empirical evidence that exposure to suffering uniquely influences caregivers' health, and discuss individual differences in caregivers' emotional reactions to partners' suffering usin...

Joint Modeling of Longitudinal Change and Survival: An Investigation of the Association Between Change in Memory Scores and Death.
Authors: Terrera GM, Piccinin AM, Johansson B, Matthews F, Hofer SM Abstract Joint longitudinal-survival models are useful when repeated measures and event time data are available and possibly associated. The application of this joint model in aging research is relatively rare, albeit particularly useful, when there is the potential for nonrandom dropout. In this article we illustrate the method and discuss some issues that may arise when fitting joint models of this type. Using prose recall scores from the Swedish OCTO-Twin Longitudinal Study of Aging, we fitted a joint longitudinal-survival model to investigate t...

Multivariate Longitudinal Modeling of Cognitive Aging: Associations Among Change and Variation in Processing Speed and Visuospatial Ability.
Authors: Robitaille A, Muniz G, Piccinin AM, Johansson B, Hofer SM Abstract We illustrate the use of the parallel latent growth curve model using data from OCTO-Twin. We found a significant intercept-intercept and slope-slope association between processing speed and visuospatial ability. Within-person correlations among the occasion-specific residuals were significant, suggesting that the occasion-specific fluctuations around individual's trajectories, after controlling for intraindividual change, are related between both outcomes. Random and fixed effects for visuospatial ability are reduced when we include struct...

Intensive Measurement Designs for Research on Aging.
The objective of intensive measurement designs is to obtain greater resolution of processes of interest that permit reliable and sensitive assessments of functioning and change in functioning and of key determinants underlying short-term variation and long-term aging and health-related change.

Maintaining a Sense of Control in the Context of Cognitive Challenge: Greater Stability in Control Beliefs Benefits Working Memory.
We examined stability vs. lability (intraindividual variability, IIV) in control beliefs and the relationships with anxiety, distraction, and performance. Age was positively associated with IIV in control and performance, and IIV increased with task difficulty. Those maintaining stable control beliefs had better performance, and showed less anxiety and distraction. Those with lower stability and less control showed steeper declines in performance and increases in distraction. The findings suggest that stability of control beliefs may serve a protective function in the context of cognitively challenging tasks. PMID: 237...

Cognitive Inconsistency and Practice-Related Learning in Older Adults.
Authors: Dzierzewski JM, Marsiske M, Morgan AA, Buman MP, Giacobbi PR, Roberts B, McCrae CS Abstract The current study examined predictors of individual differences in the magnitude of practice-related improvements achieved by 87 older adults (meanage 63.52 years) over 18-weeks of cognitive practice. Cognitive inconsistency in both baseline trial-to-trial reaction times and week-to-week accuracy scores was included as predictors of practice-related gains in two measures of processing speed. Conditional growth models revealed that both reaction time and accuracy level and rate-of-change in functioning were related t...

Optimism and Planning for Future Care Needs among Older Adults.
We examined the association of optimism with components of PFC among older adults. We also explored race differences in the relationship between optimism and PFC. In Study 1, multiple regression showed that optimism was positively related to concrete planning. In Study 2, optimism was related to gathering information. An exploratory analysis combining the samples yielded a race interaction: For Whites higher optimism, but for Blacks lower optimism was associated with more planning. High optimism may be a barrier to future planning in certain social and cultural contexts. PMID: 26045699 [PubMed - as supplied by publishe...
