The Effects of Reading Engagement on Older Adults’ Resource Allocation in Reading and Cognition

Abstract With aging, print exposure has been shown to predict effective resource allocation during reading, as well as to account for growth in certain abilities. To test the hypothesis that literacy engagement has causal effects on reading processes and the cognitive abilities on which they depend, we developed a home-based literacy intervention administered via iPads. Participants (64% female; 60-79 years of age; < 10hrs/week of reading at baseline) were randomly assigned to an 8-week reading intervention group (developed in collaboration with a Champaign Library adult literacy specialist) or to a puzzle control, both of which involved ~8hrs/week of activity engagement. At pretest and posttest, participants performed a self-paced reading task to assess resource allocation to word and conceptual processing, and completed a battery of cognitive measures assessing episodic memory, working memory, and verbal fluency (alphas ≥ .79). Based on one-tailed tests, results showed greater positive change in working memory, t(57)=1.69, p<.05, for the literacy group relative to the control, and a marginally significant difference in change in episodic memory, t(57)=1.62, p<.06, but not in verbal fluency, t< 1. In addition, there was a significant difference between conditions in change in resource allocation to conceptual processing, t(53)=1.75, p<.05. Changes in working memory and conceptual processing were positively correlated (r=.27, p=.02). These findings suggest that reading engagement may be beneficial for older adults’ growth in fluid ability, which impacts reading processes, so as to create a “virtuous spiral” of resilience between literacy engagement and ability.

Abstract Reading is an activity that has long been thought to have beneficial effects on cognitive ability, however, little is known about the effects of long-term reading engagement on cognition among older adults. Pre-test data are reported from an ongoing study of the effects of a literacy-based intervention on cognition among older adults. Participants (66.7% female) ranging from 60 to 79 years of age with education ranging from 11 to 19 years were administered a battery of measures, including print exposure checklists, which are objective indices for assessing long-term reading-related activities, as well as cognitive assessments. A composite measure of print exposure was based on the Author Recognition Test, Magazine Recognition Test, Non-fiction Author Recognition Test, and Fiction Recognition Test (alpha=.92). Cognition was assessed in a comprehensive battery, including measures of verbal ability, working memory, episodic memory, and verbal fluency (alpha=.83). Print exposure was marginally related to self-reported time spent reading (r=.27, p.4), suggesting criterion-related validity. Age-related declines were not evident for any of our cognitive measures in this sample, t(46)’s.8, and there was a modest increase in reading engagement with age (r=.36, p=.01). Controlling for verbal ability, print exposure had a significant positive influence on global cognition (standardized beta=0.38, p=.01); however, these effects were specific to episodic memory and verbal fluency, t(46)>2, p<.05. These preliminary findings are suggestive of selective cognitive benefits from continued literacy engagement in reading in later life.

AbstractGenetic factors make a substantial contribution to inter-individual variability in cognitive function. A recent meta-analysis of genome-wide association studies identified two loci, AKAP6 and MIR2113 that are associated with general cognitive function. Here, we extend this previous research by investigating the association of MIR2113 and AKAP6 with baseline and longitudinal nonlinear change across a broad spectrum of cognitive domains in community-based cohort of 1,570 older adults without dementia. Two SNPs, MIR211-rs10457441 and AKAP6-rs17522122 were genotyped in 1,570 non-demented older Australians of European ancestry, who were examined up to 4 times over 12 years. Linear mixed effects models were used to examine the association between AKAP6 and MIR2113 with cognitive performance in episodic memory, working memory, vocabulary, perceptual speed and reaction time at baseline and with linear and quadratic rates of change. AKAP6-rs17522122*T was associated with worse baseline performance in episodic memory, working memory, vocabulary and perceptual speed, but it was not associated with cognitive change in any domain. MIR2113-rs10457441*T was associated with accelerated decline in episodic memory. No other associations with baseline cognitive performance or with linear or quadratic rate or cognitive changes was observed for this SNP. These results confirm the previous finding that, AKAP6 is associated with performance across multiple cognitive domains at baseline but not with cognitive decline, while MIR2113 primarily affects the rate at which memory declines over time.

The Relationship

Abstract Research has found relationships between experiencing stressful events and lower cognitive function in late life. However, there is little research about the cumulative experiences of significant historical events and cognitive function. Historical events may be unique compared to other life events due to their potential distal relationship to the individual. This study aims to examine the relationship between experiencing significant historical events and cognitive function among Chinese older adults. Data were drawn from the PINE Study, a cohort study of 3,126 US Chinese older adults collected from 2017-2019. Participants were asked if they experienced the Japanese invasion, famine, Great Leap Forward, Vietnam War, Cultural Revolution, and the Tian’anmen Square Protests. A composite score of 0-6 was calculated to count the number experienced. Cognitive function was measured through global cognition, episodic memory, working memory, processing speed, and Chinese MMSE. Linear and quantile regression were performed. Among the participants, 1908 (61.04%) were female with mean age of 75.33 (SD=8.22) years. The average number of historical events experienced was 2.36 (SD=1.44). After adjusting for covariates, every one additional historical event experience was associated with better global cognition (b=0.26, SE=0.009, p<.01), episodic memory (b = 0.045, SE=0.012, p<.001), and processing speed (b=0.383, SE=0.135, p<.01). Number of historical events was not significantly associated with working memory or C-MMSE. The positive relationship between historical events and some cognitive domains suggests a potential resilience effect after experiencing historical events. Future research should examine whether participants found events stressful and whether there are differential relationships to cognitive function.

Background: Subjective memory complaints are a key component in mild cognitive impairment (MCI) diagnosis. However, studies that examined memory awareness among MCI participants have published contradictory results. One possible explanation for the inconsistent findings could be the disregard from the multidimensional structure of subjective memory. Objectives: The present study is directed at assessing subjective memory among healthy and MCI participants, referring to three main types of memory: episodic, semantic, and working memory. Method: Participants were 123 adults (aged 50-90). They were divided into two groups, the MCI group, and the control group, according to their objective cognitive performance in RAVL or Mo- CA tests. All participants filled a subjective memory questionnaire, assessing their awareness of episodic, semantic, and working memory. Results: MCI participants estimated their semantic memory as significantly lower in comparison to the estimation of the healthy controls. By contrast, MCI participants showed an overestimation of their episodic memory capabilities compared to the control group. No significant difference was found between groups (MCI and healthy controls) in evaluating their working memory. In addi- tion, for both groups, Pearson’s correlation revealed a significant negative correlation between age and semantic memory evaluation. Such correlation was not found for subjective episodic memory. Discussion: Findings suggest that while people with MCI exhibit poor awareness of their episodic and working memory capabilities, their awareness of their decrease in semantic memory is appar- ently intact. Therefore, it is suggested that when using the self-report criterion for MCI diagnosis, clinicians should consider the patient’s’ semantic memory complaints.

Abstract Globally, around 1 in 6 older adults experienced some form of elder mistreatment in community settings. However, little is known about the prevalence of polyvictimization, or experience of multiple forms of abuse, which may exacerbate negative outcomes over that of any one form of victimization in isolation. Data were drawn from the PINE study. Polyvictimization was defined as exposure to multiple forms of victimization, including psychological, physical, and sexual mistreatment, financial exploitation, and caregiver neglect. Cognitive function was evaluated by global cognition, episodic memory, executive function, working memory, and MMSE. Regression analyses were performed. Among 3153 participants, 128 experienced two forms of abuse while 12 experienced three or more forms of abuse. Polyvictimization was associated with lower global cognition (b=-0.05, SE=0.02, p<.05), episodic memory (b=-0.06, SE=0.03, p<.05), working memory (b=-0.14, SE=0.07, p<.05), and processing speed (b=-0.68, SE=0.33, p<.05). Interventions could target older adults with polyvictimization and protect their cognitive function.

Significant Difference

Increasing research has evidenced that our brain retains a capacity to change in response to experience until late adulthood. This implies that cognitive training can possibly ameliorate age-associated cognitive decline by inducing training-specific neural plastic changes at both neural and behavioral levels. This longitudinal study examined the behavioral effects of a systematic thirteen-week cognitive training program on attention and working memory of older adults who were at risk of cognitive decline. These older adults were randomly assigned to the Cognitive Training Group (n=109) and the Active Control Group (n=100). Findings clearly indicated that training induced improvement in auditory and visual-spatial attention and working memory. The training effect was specific to the experience provided because no significant difference in verbal and visual-spatial memory between the two groups was observed. This pattern of findings is consistent with the prediction and the principle of experience-dependent neuroplasticity. Findings of our study provided further support to the notion that the neural plastic potential continues until older age. The baseline cognitive status did not correlate with pre- versus posttraining changes to any cognitive variables studied, suggesting that the initial cognitive status may not limit the neuroplastic potential of the brain at an old age.

Neuropsychological Predictors

AbstractThis study tested the hypothesis that part of the age-related decline in performance on executive function tasks is due to a decline in episodic memory. For this, we developed a rule induction task in which we manipulated the involvement of episodic memory and executive control processes; age effects and neuropsychological predictors of task performance were investigated. Twenty-six younger (mean age, 24.0; range, 19–35 years) and 27 community-dwelling older adults (mean age, 67.5; range, 50–91 years) participated. The neuropsychological predictors consisted of the performance on tests of episodic memory, working memory, switching, inhibition and flexibility. Performance of the older adults was worse for the learning and memorization of simple rules, as well as for the more demanding executive control condition requiring the manipulation of informational content. Episodic memory was the only predictor of performance on the simple learning and memorization task condition whereas an increase in rule induction complexity additionally engaged working memory processes. Together, these findings indicate that part of the age-related decline on rule induction tests may be the result of a decline in episodic memory. Further studies are needed that examine the role of episodic memory in other executive function tasks in aging. (JINS, 2014, 20, 1–9)

Abstract Objective: Previous research suggests that chronic stress is associated with worse cognitive aging, but minimal research has examined potential mechanisms and moderators of these associations. Chronic stress is known to increase inflammation (e.g., C-reactive protein [CRP]), which has in turn been associated with worse cognition among older adults. The present study examined whether (1) CRP mediates associations between chronic stress and episodic memory and verbal fluency; and (2) these relationships differ by race/ethnicity. Methods: Participants included 18,968 adults (64% non-Hispanic White; 19% non-Hispanic Black; 14% Hispanic; 3% non-Hispanic other race/ethnicity; Mage=71.8; SDage=6.0) from the Health and Retirement Study. Chronic stress was operationalized as the occurrence and impact of eight ongoing stressors. Cross-sectional, stratified mediation models were conducted for three cognitive outcomes: immediate recall, delayed recall, and verbal fluency. Covariates included sociodemographics and vascular disease burden. Results: Chronic stress was associated worse immediate recall (beta=-.028). Higher CRP was not associated with any cognitive domains. Non-Hispanic Black participants reported more chronic stress than non-Hispanic White and Hispanic participants. Chronic stress was less strongly associated with higher CRP in non-Hispanic Black (beta=-.035) participants than non-Hispanic White (beta=.046) or Hispanic (beta=.059) participants. Discussion: Chronic stress may negatively influence episodic memory, but findings do not suggest that CRP mediates links between chronic stress and cognition. CRP may not track as closely with chronic stress among non-Hispanic Black older adults who may experience additional risk factors for inflammation and/or adapt to increased chronic stress.

BackgroundProspective studies suggest that tea consumption may decrease the risk for cognitive impairment in late life. However, little research has examined the association between tea consumption and cognitive performance across multiple domains. In addition, no research has examined the benefit of tea consumption on cognitive performance among older adults with existing impairment.AimsThe current study examined the association between tea consumption and performance on tasks of global cognitive function, episodic memory and executive function in cognitively healthy (CH) older adults and older adults with mild cognitive impairment (MCI).MethodsThe analytical sample included 1849 community-dwelling older adults from the Shanghai Brain Aging Study (65.6% female, mean age of 69.50 (8.02) years). Following ascertainment of cognitive function, 816 were categorised as MCI. In addition to completion of a demographics questionnaire, participants reported their tea consumption and completed a battery of tests to measure global cognitive function, episodic memory and working memory.ResultsIndependent analyses of covariance revealed a significant association between tea consumption and measures of episodic memory; however, these associations were restricted to CH older adults but not older adults with MCI. Tea consumption was not associated with working memory performance.ConclusionsThe current study suggests that the benefit of tea consumption is restricted to cognitively healthy older adults and does not extend to older adults with MCI.

A broad literature has explored racial disparities in cognitive aging. Research incorporating sociocultural factors would provide a more comprehensive understanding of minority aging. This study aims to investigate the role of family typology in cognition among U.S. Chinese immigrants. Data were derived from the Population Study of Chinese Elderly in Chicago (PINE). Family typology included tight-knit, unobligated ambivalent, commanding conflicted, and detached typologies. Cognition was evaluated by global cognition, episodic memory, working memory, executive function, and mini-mental state examination (MMSE). Linear and quantile regressions were used. Older adults with detached and commanding conflicted typologies reported lower global cognition than those with unobligated ambivalent typology. Detached, commanding conflicted, and tight-knit typologies were associated with poorer performance in episodic memory, working memory and MMSE than unobligated ambivalent typology, respectively. Social service providers could be aware of multifaceted family relationships when developing interventions for cognitive function and understand family typology as a whole.
