Engagement In Cognitive Activities Research Articles

Daily cognitive complaints and engagement in older adulthood: Personality traits are more predictive than cognitive performance.

Cognitive complaints and engagement in cognitive activities are two consistent predictors of cognitive aging outcomes, including risk for nonnormative decline. Though research has considered predictors of complaints and engagement in general, little work has attended to the fact that these fluctuate at the daily level. The current study examined individual difference predictors of means and variability for engagement and complaints across 10 days in a sample of older adults (n = 136; Mage = 70.45 years). When comparing personality traits to indicators of cognitive performance, personality differences appeared better unique predictors for these measures of daily cognitive life. Specifically, even when accounting for demographics, measures of cognitive performance, and the other personality traits investigated, older adults higher on openness to experience reported fewer daily cognitive complaints and more engagement on average, as well as greater daily variability in engagement. In addition, higher neuroticism predicted greater variability in reports of cognitive complaints across days. Implications are discussed with respect to how these findings advance our understanding of cognitive complaints and engagement in daily life.

THE ROLE OF POLYGENIC SCORE AND COGNITIVE ACTIVITIES ON COGNITIVE FUNCTIONING OF OLDER ADULTS

Purpose of study: This study investigated whether and to what extent genetics for cognition and engagement in cognitive activities are related to trajectories of cognitive functioning in older adulthood. Furthermore, we explored whether engaging in cognitive activities could moderate the effect of genetic traits on cognitive functioning in general and across different dimensions: fluid and crystallized intelligence. Design and Methods: Growth curve models were estimated using the sample of 3,129 individuals aged 50 or older (10,000 observations) in the U.S. from 2000-2012 waves of the Health and Retirement Study. Polygenic score for general cognition (PGS) was used to measure genetic traits for cognition, and the number of hours spent per week on each of nine cognitive activities was used to measure individuals’ level of the engagement in cognitive activities. Results: PGS for cognition, reading books, using a computer, and playing cards/games/solving puzzles had positive effects on cognitive functioning. The positive effect of PGS on cognitive functioning was reduced from excessive TV watching. The positive effect of PGS on cognitive functioning was strengthened by spending more hours reading papers/magazines. The measure of fluid, rather than crystallized intelligence, appeared to drive these results. Conclusion: Findings suggests that while genetic factors predict cognitive functioning, engaging in different types of cognitive activities could yield different cognitive functioning trajectories in later life. Practical implications are that older adults should be more selective when choosing their leisure activities to promote cognitive health.

MULTIPLE CHRONIC CONDITIONS AND RISK OF DEMENTIA AND COGNITIVE IMPAIRMENT

This study explores the relationship between the presence of multiple chronic condition and risk of dementia and cognitive impairment with no dementia (CIND) among older Americans. The study sample included 617 participants aged 70 years and older from the Aging, Demographics, and Memory Study (ADAMS). An expert consensus panel of the ADAMS data provided each participant a cognitive diagnosis into 1) no cognitive impairment, 2) CIND, or 3) dementia. The presence of multiple chronic condition was defined as having three or more chronic conditions in this study (e.g., heart attack, stroke, respiratory problems, cancer, hypertension, diabetes). Functional limitation, depression, cognitive activity engagement, apolipoprotein E (ApoE), and sociodemographic characteristics were included as covariates. A multinomial logistic regression analysis showed that individuals who have multiple chronic conditions have increased odds of being diagnosed with CIND versus no cognitive impairment controlling for other covariates. However, multiple chronic condition was not associated with increased risk of being diagnosed with dementia versus no cognitive impairment. Conclusion: The finding suggests that the presence of multiple chronic conditions may be a risk factor for cognitive impairment in later life. However, further investigation using a longitudinal design is needed to better understand the relationship between cognition and multiple chronic conditions.

Environmental Factors Associated with Chinese Older Immigrants' Social Engagement.

Prior research has shown that social engagement is beneficial to older adults' health and well-being. This study examined the association between environmental factors and social engagement of older Chinese immigrants in the United States. A cross-sectional data set of Chinese immigrants in the greater Chicago, IL, area (Population Study of Chinese Elderly; n = 3159), was used in this study. Multiple regression models were used to test the associations between older adults' engagement in cognitive and social activities and environmental factors, including financial difficulties, social support, neighborhood cohesion, neighborhood disorder, and sense of community. Eight questions measuring participants' engagement in cognitive and social activities, a single-item question measuring financial difficulties, a 12-item social support measurement, an eight-item neighborhood cohesion measurement, and a six-item neighborhood disorder and sense of community scale. Having fewer financial difficulties and a cohesive neighborhood is related to a higher level of engagement in both cognitive and social activities. More social support from family and friends and a sense of community are associated with higher levels of social activities engagement, but not cognitive activity engagement. Neighborhood cohesion has a stronger association with social engagement than other environmental factors and most individual-level factors. Surprisingly, neighborhood disorder is positively related to social activity engagement, which needs further examination. The associations between environmental factors and social engagement showed no significant difference between healthy and unhealthy older adults. This study highlights the need for policies and programs to promote an active lifestyle among older immigrants by creating facilitative social and physical environments.

An active cognitive lifestyle as a potential neuroprotective factor in Huntington's disease

A cognitive stimulating lifestyle has been observed to confer cognitive benefits in multiple neurodegenerative diseases. However, the underlying neurobiological basis of this phenomenon remains unclear. Huntington's disease can provide a suitable model to study the effects and neural mechanisms of cognitive engagement in neurodegeneration. In this study, we investigate the effect of lifestyle factors such as education, occupation and engagement in cognitive activities in Huntington's disease gene carriers on cognitive performance and age of onset as well as the underlying neural changes sustaining these effects, measured by magnetic resonance imaging. Specifically, we analyzed both gray matter volume and the strength of connectivity of the executive control resting-state network. High levels of cognitive engagement were significantly associated with more preserved executive functions, a delay in the appearance of symptoms, reduced volume loss of the left precuneus and the bilateral caudate and a modulation of connectivity strength of anterior cingulate cortex and left angular gyrus with the executive control network. These findings suggest that a cognitively stimulating lifestyle may promote brain maintenance by modulating the executive control resting-state network and conferring protection against neurodegeneration, which results in a delayed onset of symptoms and improved performance in executive functions.

Change in Engagement in Cognitive Activity and Risk for Mild Cognitive Impairment in a Cohort of Older Adults: The Monongahela-Youghiogheny Healthy Aging Team (MYHAT) Study.

Engagement in cognitively stimulating activities is gaining prominence as a potential strategy to maintain cognitive functioning in old age. In a population-based cohort of individuals aged 65+ years, we examined patterns of change in frequency of engagement in total cognitive activity (TCA), higher cognitive activity (HCA), and frequent cognitive activity (FCA) based on the Florida Cognitive Activities Scale over an average of 3.62 years, and whether these patterns were associated with incident mild cognitive impairment (MCI) during this same period. Among 867 cognitively normal participants, 129 (15%) progressed to MCI. Latent class trajectory modeling identified high and stable, slowly, and quickly declining patterns for TCA; high and stable, slowly declining, and slowing increasing patterns for FCA; and high and stable, and slowly declining patterns for HCA. Separate, adjusted Cox proportional hazard models, revealed that compared with the high, stable pattern, both slow decline [hazard ratio (HR), 2.5; 95% confidence interval (CI), 1.5-4.0] and quick decline (HR, 11.0; 95% CI, 6.3-19.2) in TCA, and slow decline in the FCA (HR, 8.7; 95% CI, 5.3-14.3) and HCA (HR, 3.4; 95% CI, 2.0-5.6) subscales increased risk for incident MCI. Maintaining engagement in cognitive activities may be protective against progression to MCI, alternatively, declining engagement may be a marker for impending cognitive impairment.

Developmental suppression of forebrain trkA receptors and attentional capacities in aging rats: A longitudinal study

Basal forebrain (BF) cholinergic neurons innervating the cortex regulate cognitive, specifically attentional, processes. Cholinergic atrophy and cognitive decline occur at an accelerated pace in age-related neurodegenerative disorders such as Alzheimer’s disease; however, the mechanism responsible for this phenomenon remains unknown. Here we hypothesized that developmental suppression of nerve growth factor signaling, mediated via tropomyosin-related kinase A (trkA) receptors, would escalate age-related attentional vulnerability. An adeno-associated viral vector expressing trkA shRNA (AAV-trkA) was utilized to knockdown trkA receptors in postnatal rats at an ontogenetic time point when cortical cholinergic inputs mature, and the impact of this manipulation on performance was assessed in animals maintained on an operant attention task throughout adulthood and until old (24 months) age. A within-subject comparison across different time points illustrated a gradual age-related decline in attentional capacities. However, the performance under baseline and distracted conditions did not differ between the AAV-trkA-infused and animals infused with a vector expressing shRNA against the control protein luciferase at any time point. Additional analysis of cholinergic measures conducted at 24 months showed that the capacity of cholinergic terminals to release acetylcholine following a depolarizing stimulus, cortical cholinergic fiber density and BF cholinergic cell size remained comparable between the two groups. Contrary to our predictions, these data indicate that developmental BF trkA disruption does not impact age-related changes in attentional functions. It is possible that life-long engagement in cognitive activity might have potentially rescued the developmental insults on the cholinergic system, thus preserving attentional capacities in advanced age.

Distinct effects of late adulthood cognitive and physical activities on gray matter volume.

Engagement in cognitive activity (CA) and physical activity (PA) during the lifespan may counteract brain atrophy later in life. Here, we investigated engagement in CA and PA during late adulthood in association with gray matter volume (GM) in normal older adults, with special focus on the hippocampus. Forty-five cognitively normal older individuals (mean age: 72) underwent T1-weighted MRI and self-reported CA and PA assessment. Whole brain voxel-wise multiple regression models were carried out to assess the relationships between CA, PA and GM volume adjusted by age and sex. Further adjustment for years of education and risk factors were performed. Voxel-wise analyses were projected on 3D hippocampal surface views. Cognitive activity and PA demonstrated independent regional associations with GM after adjustment for confounders. Cognitive activity was related to greater GM in extended brain areas including frontal, temporal and parietal cortices, while PA was associated with increased GM in the prefrontal, insular and motor cortices. Regression maps projected on the hippocampal surface showed a common association of PA and CA within the anterior part of the hippocampus, although the effect of CA was more subtle and also extended to the posterior part. Engagement in PA and CA in late adulthood were independently related to regional GM volume, notably in aging and AD vulnerable areas. These results support the idea that both PA and CA- based interventions may be suitable to promote brain health in late adulthood. The potential synergistic effects of PA and CA need to be addressed in future studies including larger samples.

Is visual function associated with cognitive activity engagement in middle-aged and elderly individuals? A cross-sectional study

ObjectiveThis study investigated whether visual function is associated with cognitive activity engagement and mild cognitive impairment in middle-aged and elderly individuals. MethodThis cross-sectional study was conducted on 120 individuals aged 50–89. The Florida Cognitive Activity Scale (FCAS) was used to assess cognitive activity engagement. Visual function was assessed by near visual acuity (nVA) and contrast sensitivity (CS), and both combined to obtain a visual function (VF) compound score. Multivariable linear regression models, adjusted for confounders, were used to assess the association between the determinants and FCAS. ResultsAfter confounder adjustment, nVA was not associated with overall cognitive activity engagement. CS was significantly associated with the FCAS “Higher Cognitive Abilities” subscale score (BHC=5.5 [95% CI 1.3; 9.7]). Adjustment for nVA attenuated the association between CS and engagement in tasks of Higher Cognitive Abilities (BHC=4.7 [95% CI 0.1; 9.3]).In retired individuals (N=87), the VF compound score was associated with a lower Cognitive Activity Scale score (BCA=−1.2 [95% CI −2.3; −0.1]), lower Higher Cognitive Abilities score (BHC=−0.7 [95% CI −1.3; −0.1]) and lower Frequent Cognitive Abilities score (BFA=−0.5 [95% CI −0.9; −0.1]). ConclusionCS, but not nVA, plays a role in engagement in tasks associated with Higher Cognitive Abilities in middle-aged and elderly individuals. In retired individuals, the VF compound score is associated with lower Cognitive Activity score, lower Higher Cognitive Abilities score and lower Frequent Cognitive Abilities score.

Participation in cognitively-stimulating activities is associated with brain structure and cognitive function in preclinical Alzheimer's disease.

This study tested the hypothesis that frequent participation in cognitively-stimulating activities, specifically those related to playing games and puzzles, is beneficial to brain health and cognition among middle-aged adults at increased risk for Alzheimer's disease (AD). Three hundred twenty-nine cognitively normal, middle-aged adults (age range, 43.2-73.8years) enrolled in the Wisconsin Registry for Alzheimer's Prevention (WRAP) participated in this study. They reported their current engagement in cognitive activities using a modified version of the Cognitive Activity Scale (CAS), underwent a structural MRI scan, and completed a comprehensive cognitive battery. FreeSurfer was used to derive gray matter (GM) volumes from AD-related regions of interest (ROIs), and composite measures of episodic memory and executive function were obtained from the cognitive tests. Covariate-adjusted least squares analyses were used to examine the association between the Games item on the CAS (CAS-Games) and both GM volumes and cognitive composites. Higher scores on CAS-Games were associated with greater GM volumes in several ROIs including the hippocampus, posterior cingulate, anterior cingulate, and middle frontal gyrus. Similarly, CAS-Games scores were positively associated with scores on the Immediate Memory, Verbal Learning & Memory, and Speed & Flexibility domains. These findings were not modified by known risk factors for AD. In addition, the Total score on the CAS was not as sensitive as CAS-Games to the examined brain and cognitive measures. For some individuals, participation in cognitive activities pertinent to game playing may help prevent AD by preserving brain structures and cognitive functions vulnerable to AD pathophysiology.

Productive group engagement in cognitive activity and metacognitive regulation during collaborative learning: can it explain differences in students’ conceptual understanding?

This paper addresses the nature and significance of productive engagement in cognitive activity and metacognitive regulation in collaborative learning tasks that involve complex scientific knowledge. A situative framework, combining the constructs of social regulation and content processing, provided the theoretical basis for the development of a comprehensive coding scheme for interactive data analysis. An empirical study was conducted with two groups of university students working on two science-learning tasks. It examined the function of metacognitive regulation to control the flow of cognitive activity, and the extent to which group differences in cognitive and metacognitive regulation processes during collaborative learning could explain differences in the groups’ learning outcomes. The findings provide validation of the framework and its derived coding scheme. An example of a way in which a group engages in socially shared metacognitive regulation is presented to demonstrate how the coding scheme was applied to the data. Theoretical and empirical implications of the findings are discussed.

BDNF and COMT polymorphisms have a limited association with episodic memory performance or engagement in complex cognitive activity in healthy older adults

Cognitive decline is a major factor in lowering the quality of life in older populations, and contributes substantially to social, economic, and health costs. As humans age, cognitive function decreases differentially, and individual differences in cognitive ageing are likely attributed to a range of causes, including environmental and genetic influences. The current study included 360 participants (240 females and 120 males) aged between 50 and 79years from the Tasmanian Healthy Brain Project. The brain-derived neurotrophic factor (BDNF) Val66Met and Catechol-O-Methyltransferase (COMT) Val158Met polymorphisms were examined for their association with visual and auditory episodic memory performance. The polymorphisms were also investigated for their association with reported life-long engagement in complex cognitive activity using a retrospective questionnaire. Relative to the demographic variables, the gene variations were found to have no association with episodic memory performance, with the exception of the COMT polymorphism on a single measure of auditory memory (RAVLT). Several other studies also demonstrated that these polymorphisms have no, small, or inconsistent effects on memory function. The BDNF Val66Met and COMT Val158Met polymorphisms were also found to be of little significance to active engagement in complex cognitive activity throughout most of the lifespan. An association was detected between BDNF Val66Met and engagement in cognitive activity in early life (p=.04, d=.23), however this did not reach significance when adjusted for multiple comparisons. The biological mechanisms that underlie engagement in cognitive activity are elusive, thus the potential relationship between BDNF Val66Met genotype and early life cognitive engagement warrants further investigation.

The Impact of Exercise, Cognitive Activities, and Socialization on Cognitive Function

Currently, there are no effective treatments for Alzheimer's disease and related disorders and age continues to be a robust risk factor. Thus, population aging in the United States may have catastrophic results if interventions are not found and implemented. This study examines possible associations between cognitive impairment and exercise, cognitive activities, and socialization. Cognitive activities, socialization, and exercise were assessed at baseline, and cognitive function was measured at baseline, 5-year, and 10-year follow-up. Controlling for baseline cognitive function, age, sex, education, diabetes, and hypertension, linear regression was performed. Engagement in cognitive activities was inversely associated with the onset of cognitive impairment at 5-year follow-up but was no longer significant at 10-year follow-up. Exercise was associated with a lower risk of cognitive impairment at 10-year follow-up but was not significant at 5-year follow-up. Associations with socialization were not statistically significant at either follow-up.

Cognitive Activity Engagement Predicts Future Memory and Executive Functioning in Older Adults

This study examined cognitive activity engagement, depression, executive functioning, and memory in a sample of older adults. Participants were assessed at baseline and 15 months later. Depression and activity level were significantly correlated at baseline, such that increased depressive symptoms were associated with decreased cognitive activity. Higher baseline activity scores, particularly on a measure of participation in cognitively challenging activities, predicted higher scores on memory and executive functioning tests at follow up. Findings highlight the benefits of activity engagement in later life, such that activity engagement is associated with reduced cognitive decline in older adults.

Is there a home advantage in school readiness for young children? Trends in parent engagement in cognitive activities with young children, 1991–2001

The desire to understand the home advantage has spurred a large body of research describing the contribution of differences in family background and parenting styles to school readiness and the achievement gap. Using the National Household Education Survey at two time points provides a fuller picture of the trends in parenting and cognitive activities with young children before the onset of formal schooling. The results presented here show that although more educated parents participate more in cognitive activities with their young children in 1991 and 2001, participation is increasing for all parents. This is true for a widely expected parental activity, reading to your child, and for a direct instruction activity, teaching letters, words, and numbers. It is also true for the more creative activities of music, arts and crafts, and telling stories. Contrary to images of some families as deficient and others as overly exuberant, all families in this sample are increasing engagement with their young children in a range of cognitive activities aimed at school readiness because parents as well as children get socialized to the culture of schooling. Modern American schooling requires parents to be engaged in the education process of their children and attempt to create advantage for them.

Prior cognitive activity implicitly modulates subsequent emotional responses to subliminally presented emotional stimuli

It has been reported that engagement in several kinds of cognitive activity can successfully inhibit unpleasant emotions. In this study, we tried to replicate the previous finding that cognitive activity can modulate subsequent psychological and physiological emotional processes and to investigate whether prior cognitive activity can attenuate implicit emotional processes triggered by subliminal emotional stimuli. Sixty students were randomly divided into three groups (cognitive task group, noncognitive task group, control group). The cognitive task group was asked to engage in an n-back task, while the control group was asked to stay calm. The noncognitive task group was asked to do a handgrip-squeezing task. All participants then engaged in a version of a subliminal affective priming task where they were unconsciously exposed to affectively negative pictures. The cognitive task group showed lower negative experiences after the subliminal affective priming task and a substantial reduction in their heart rate responses, as compared with the other groups. These results provide evidence that engagement in cognitive activity can attenuate emotional processes in an automatic and unconscious manner.

Investment trait, activity engagement, and age: independent effects on cognitive ability.

In cognitive aging research, the “engagement hypothesis” suggests that the participation in cognitively demanding activities helps maintain better cognitive performance in later life. In differential psychology, the “investment” theory proclaims that age differences in cognition are influenced by personality traits that determine when, where, and how people invest their ability. Although both models follow similar theoretical rationales, they differ in their emphasis of behavior (i.e., activity engagement) versus predisposition (i.e., investment trait). The current study compared a cognitive activity engagement scale (i.e., frequency of participation) with an investment trait scale (i.e., need for cognition) and tested their relationship with age differences in cognition in 200 British adults. Age was negatively associated with fluid and positively with crystallized ability but had no relationship with need for cognition and activity engagement. Need for cognition was positively related to activity engagement and cognitive performance; activity engagement, however, was not associated with cognitive ability. Thus, age differences in cognitive ability were largely independent of engagement and investment.

Parenting for Cognitive Development from 1950 to 2000

Over the second half of the twentieth century, changes occurred in parent reports of their engagement in cognitive activities with their young children in the United States. This article argues that the growing trend of parenting for cognitive development in young children in the latter half of the twentieth century is associated with the institutionalization of mass schooling and the legitimization of cognitive development as a central feature of early childhood. The results show that all parents increasingly spent more time engaging in activities related to cognitive development so that by 1991, it was normative behavior. In addition, the results show that mothers’ education became an increasingly better predictor of parenting for cognitive development over the second half of the twentieth century but in the last decade of the twentieth century, the association with mothers’ education remained constant or diminished slightly as all families increasingly engaged in cognitive development activities.

Early intervention for cognitive decline: is there a role for multiple medical or behavioural interventions?

Early medical or behavioural intervention to slow cognitive decline might be a viable strategy for reducing disability and rates of institutional care in older persons. This paper details the published work supporting cross-sectional and longitudinal associations between vascular risk factors, depressive symptoms and progressive cognitive decline. Evidence for the beneficial effects of providing relevant interventions is assessed. Relevant published work from the areas of dementia research, 'vascular depression' and the cognitive benefits that might result from treating vascular risk factors, managing depression or promoting nutrition, cognitive or physical exercise was ascertained from electronic database searches and recent reviews of key areas. The existing published work does not provide many examples of early intervention strategies that target vascular strategies or active treatment of depression to reduce the rate of cognitive decline. Most studies have major limitations including the evaluation of only single-risk-factor interventions, the observational designs and the inadequate measurement of cognition. An optimal early intervention strategy might be to target multiple risk factors within relevant experimental or health service frameworks. Early identification and multifaceted reduction of vascular risk factors, active management of depression, engagement in cognitive activity and physical exercise and promotion of better nutrition might together help to slow some forms of cognitive decline or progression to dementia. This health services approach now requires systematic evaluation.
