Skill-learning variety and frequency on long-term cognitive performance in older adults
Intervention studies have shown that novel skill learning improves short-term and long-term cognitive abilities, but it is unclear how frequency and variety in skill learning impacts cognitive outcomes. Observational (nonintervention) studies have shown that frequent and varied activity engagement in older adulthood relates to better cognitive abilities. Using a 2 × 2 design, the present intervention study investigated the optimal dosage of varie…
Long-Term Effects of a Real-World Multi-Skill Intervention on Older Adults’ Growth Mindset
Although there have been interventions to increase growth mindset, little is known about their effectiveness over a longer period, especially for older adults. This study with older adults investigated the long-term effects of a learning intervention that included growth mindset lectures and discussions on growth mindset. In Study 1 ( n = 27), participants were tracked for one year after a 12-week intervention. We found that an increased growth m…
Perceived Control, Cognitive Training, and Incident Alzheimer’s Disease and Related Dementias in the Active Study
Objectives Greater perception of control over important life outcomes has been linked to better cognitive performance and greater benefits from cognitive training interventions among older adults. However, it is not yet known whether perceived control predicts incident Alzheimer’s disease and related dementias (ADRD) or influences links between cognitive training and ADRD incidence. Methods Data were obtained from 2,021 participants in the Advanc…

Hearing and vision impairment and social isolation over 8 years in community-dwelling older adults
Greater clinical awareness of hearing impairment as a risk factor for social isolation can increase opportunities to identify and aid older adults who may benefit from resources and interventions to increase social connection and mitigate social isolation
Growth Mindset Predicts Cognitive Gains in an Older Adult Multi-Skill Learning Intervention
Growth mindset (belief in the malleability of intelligence) is a unique predictor of young learners’ increased motivation and learning, and may have broader implications for cognitive functioning. Its role in learning in older adulthood is unclear. As part of a larger longitudinal study, we examined growth mindset and cognitive functioning in older adults engaged in a 3-month multi-skill learning intervention that included growth mindset discussi…
The Impact of Learning Multiple Real-World Skills on Cognitive Abilities and Functional Independence in Healthy Older Adults
OBJECTIVES: The natural learning experience from infancy to emerging adulthood, when considerable cognitive and functional growth is observed, mandates learning multiple real-world skills simultaneously. The present studies investigated whether learning multiple real-world skills simultaneously is possible in older adults and also whether it improves both their cognitive abilities (working memory, episodic memory, and cognitive control) and funct…
Effects of Cognitive Training on Alzheimer’s Disease and Related Dementias
Objective: We examined whether social determinants of health (SDoH) are associated with Alzheimer's disease and related dementias (ADRD) risk and the effects of cognitive training over a 20-year follow-up period. Methods: Data were obtained from 1605 participants in ACTIVE. SDoH measures were created using baseline data at the individual and neighborhood level. Incident ADRD was defined using administrative claims data (1999-2019). Cause-specific…

Participants were cognitively and physically healthy, community-dwelling adults aged 65 and older. Cox proportional hazard…
Learning as an Important Privilege
Research has demonstrated the cognitive and mental health benefits of learning new skills and content across the life span, enhancing knowledge as well as cognitive performance. We argue that the importance of this learning – which is not available equally to all – goes beyond the cognitive and mental health benefits. Learning is important for not only the maintenance, but also enhancement of functional independence in a dynamic environment, such…
Importance of Driving and Potential Impact of Driving Cessation for Rural and Urban Older Adults
PURPOSE: Analyses compared older drivers from urban, suburban, and rural areas on perceived importance of continuing to drive and potential impact that driving cessation would have on what they want and need to do. METHODS: The AAA LongROAD Study is a prospective study of driving behaviors, patterns, and outcomes of older adults. A cohort of 2,990 women and men 65-79 years of age was recruited during 2015-2017 from health systems or primary care …
Residence in urban and rural areas over the life course and depression among Ghanaian and South African older adults
Using Cognitive Intraindividual Variability to Measure Intervention Effectiveness
The Experience Corps program resulted in an improvement in cognitive performance as measured by IIV. Analyzing previously collected data with nontraditional measures of cognition, such as IIV, may be a potentially fruitful and cost-effective method for understanding how interventions impact cognition in aging populations
Evaluating Successful Aging in Older People Who Participated in Computerized or Paper-and-Pencil Memory Training
Background. The evaluation of successful aging includes objective criteria to measure cognitive function and psychological well-being and levels of functional capacity needed to perform daily activities related to the preservation of autonomy. In addition, the emergence of computerized cognitive training programs has allowed us to use a new class of tools to verify the theoretical postulates of neural plasticity in aging. Objective. The present s…
Comparing Web-Based and Classroom-Based Memory Training for Older Adults
Although no significant training effects were found, we demonstrated that a web-based platform is an acceptable and feasible mode to provide memory training to healthy older adults. Further studies are needed to investigate the potential of web-based memory training programs for improving cognition and function in cognitively healthy older adults
Retracted and replaced
Our findings demonstrate the feasibility and potential of conducting a real-world skill-learning intervention involving learning three novel skills with older adults. Our multiskill intervention may provide broad cognitive gains, akin to the benefits experienced earlier in the life span
Identifying mental health problems and Idioms of distress among older adult internally displaced persons in Georgia
Social Network Characteristics and Cognition in Middle-Aged and Older Adults
We examined the relationship between social network characteristics and global cognitive status in a community-based sample of 354 adults aged 50+ and with Mini-Mental State Examination (MMSE) scores of 28+ at baseline. Multivariate analyses indicated that interaction in larger social networks related to better maintenance of MMSE scores and reduced odds of decline to population-based lower quartile MMSE scores at follow-up 12 years later. At fol…
Social Integration and Social Support Among Older Adults Following Driving Cessation
Social integration is negatively affected by driving cessation even among elders who feel competent in using alternative forms of transportation, at least concerning networks of friends
The Baltimore Experience Corps Trial
Results provide the first-ever, large-scale experimental demonstration that participation in an intergenerational civic engagement program can positively alter self-perceptions of generativity in older adulthood
Memory self-efficacy and performance differences in young and old adults
We evaluated the hypothesis that mnemonic training would result in higher memory self-efficacy and better memory performance in young and old adults. Forty-eight yound adults (17- to 19-year-olds) and 45 old adults (60- to 78-year-olds) received either training in the method of loci or no training and were given either performance feedback or no feedback on a serial-word recall task. Ss were tested at pre- and posttraining and were asked to rate …
The Long-Term Relationship Between High-Intensity Volunteering and Physical Activity in Older African American Women
EC volunteers reported a sustained increase in physical activity as compared with the comparison cohort. Baseline physical activity for individuals with a median propensity score was 420 kcal/wk for both groups. At 36 months, EC volunteers reported 670 kcal/week compared with 410 kcal/week in WHAS (p = .04). Discussion These findings suggest that high-intensity senior service programs that are designed as health promotion interventions could lead…

Predicting Memory Training Response Patterns
Previous research suggests that there is a great deal of variability among older adults' response to memory training. Using latent class analysis, we examined data from the memory training arm of the Advanced Cognitive Training for Independent and Vital Elderly Trial (ACTIVE), a large randomized controlled cognitive training trial, to determine if there were distinct patterns of responsiveness to training. Additionally, we examined whether baseli…
Race-Related Disparities in 5-Year Cognitive Level and Change in Untrained Active Participants
Race-related results in the current study are consistent with previous research suggesting that social advantage factors such as education have a stronger influence on the level of performance than the rate of change. The small remaining effects of being African American on performance levels likely reflect uncontrolled variation in factors like literacy and financial advantage
Depressive Symptoms and Memory Performance Among Older Adults
Findings suggest that elevated depressive symptoms may predict declines in memory ability over time, but do not attenuate gains from training. Training provides a potential method of improving memory which is robust to effects of depression
Modeling Learning and Memory Using Verbal Learning Tests
This study contributes to the understanding of the mechanisms by which training benefits memory and expands current knowledge by reporting long-term changes in initial recall and learning, as measured from growth models and by characterization of the impact of memory training on these components.

Association Between Insomnia Symptoms and Functional Status in U.S. Older Adults
Among older adults, insomnia symptoms are associated with a greater odds of limitation in household activities and of restricted participation in valued activities. Insomnia interventions may improve functioning and quality of life among elders
The Influence of Cognitive Training on Older Adults’ Recall for Short Stories
Results suggest that multifactorial memory training can improve verbatim recall for prose, but the effect does not last without continued intervention
Clients Nearing Death
The literature on the relationship between psychosocial events and dying and death is reviewed from a behavioral perspective. Individual control for predictability of endogenous and exogenous events is identified as an intervening construct in the relationship between the timing of death and a variety of psychosocial factors. It is then argued that behavioral self-management is a potentially useful therapeutic tool for working with clients who ar…
