Abstract Introduction: The cognitive functioning, as a general measure, is a criterion commonly used to define and operationalize successful aging. (Project-Conacyt-256589) The aim of this study is to analyze specific domains of cognitive function and its relationship with the successful aging in older adults. Methods: Population based, random sample included n=453 community-dwelling older adults 60-years and older (mean age=72.51,SD=8.11 years,59.4% women). Cognitive functioning was assessed by a comprehensive battery including working memory(Digit Span Backward WAIS-IV), episodic memory, meta-memory(self-report), processing speed(Symbol Digit WAIS-IV), attention(TMT-A), executive functioning(TMT-B), learning potential(RAVLT), language(FAS), visuospatial skills(Block Design WAIS-IV). Successful aging was operationalized as no important disease, no disability, physical functioning, cognitive functioning, and being actively engaged. Sociodemographic and health data were also asked. Data were analyzed in SPSSv24, MANOVAs and size effects were calculated. Results: In total 11.2% were successful agers and 11.4% had Mild Cognitive impairment. Global cognitive functioning was significantly related to the achievement of successful aging criteria. Cognitive functioning had a significant effect on successful aging, specifically executive functions (F=1.07,p=.000) explained 32.7% of the variance, attention explained 29.8% (F=1.19,p=.006), processing-speed 21% (F=1.38,p=.000), and learning potential 21.5% ((F=1.12,p=.005). Language, visuospatial skills, working memory and meta-memory had a very small effect. Conclusion: Knowledge generated by this study reveals the specific role of cognitive domains on successful aging, and sets a scenario to promote successful aging, through alternatives centered in the improvement of cognition in the older adults.

Abstract Adherence to health behaviors is often poor, including adherence to at-home technology-based interventions. This study (N=120) explored adherence to a cognitive training intervention delivered via computer tablet, assessed adherence over a 4.5 month period, explored how individual difference factors shaped adherence, and tested the efficacy of message framing manipulations (positive vs. negative framing) in boosting adherence. Individual difference factors predicted adherence, including variations in self-efficacy and belief in the efficacy of cognitive training. Overall message framing had little impact. However, during the final portion of the study in which participants were asked to play as much or as little as they wanted instead of following a schedule, participants who received positively framed messages engaged with the intervention more. Implications for predicting and boosting adherence to home delivered technology-based interventions will be discussed.

AbstractThe Relative Consequence Model proposes multiple sclerosis (MS) patients have a fundamental deficit in processing speed that compromises other cognitive functions. The present study examined the mediating role of processing speed, as well as working memory, in the MS-related effects on other cognitive functions for early relapsing-remitting patients. Seventy relapsing-remitting MS patients with disease duration not greater than 10 years and 72 controls completed tasks assessing processing speed, working memory, learning, and executive functioning. The possible mediating roles of speed and working memory in the MS-related effects on other cognitive functions were evaluated using structural equation modeling. Processing speed was not significantly related to group membership and could not have a mediating role. Working memory was related to group membership and functioned as a mediating/intervening factor. The results do not support the Relative Consequence Model in this sample and they challenge the notion that working memory impairment only emerges at later disease stages. The results do support a mediating/intervening role of working memory. These results were obtained for early relapsing-remitting MS patients and should not be generalized to the broader MS population. Instead, future research should examine the relations that exist at other disease stages. (JINS, 2013, 19, 1–12)

Psychosocial Variables

AbstractNegative affect (e.g., depression) is associated with accelerated age-related cognitive decline and heightened dementia risk. Fewer studies examine positive psychosocial factors (e.g., emotional support, self-efficacy) in cognitive aging. Preliminary reports suggest that these variables predict slower cognitive decline independent of negative affect. No reports have examined these factors in a single model to determine which best relate to cognition. Data from 482 individuals 55 and older came from the normative sample for the NIH Toolbox for the Assessment of Neurological and Behavioral Function. Negative and positive psychosocial factors, executive functioning, working memory, processing speed, and episodic memory were measured with the NIH Toolbox Emotion and Cognition modules. Confirmatory factor analysis and structural equation modeling characterized independent relations between psychosocial factors and cognition. Psychosocial variables loaded onto negative and positive factors. Independent of education, negative affect and health status, greater emotional support was associated with better task-switching and processing speed. Greater self-efficacy was associated with better working memory. Negative affect was not independently associated with any cognitive variables. Findings support the conceptual distinctness of negative and positive psychosocial factors in older adults. Emotional support and self-efficacy may be more closely tied to cognition than other psychosocial variables. (JINS, 2014, 20, 1–9)

New Learning

It is well-established that as people age, deterioration in cognitive abilities including processing speed, memory, and cognitive flexibility occurs, although vast individual differences occur in the rate and consequences of this decline (Christensen, 2001). Anxiety and depression in late life are also associated with specific cognitive deficits in memory and executive functioning that may impact on new learning (Yochim et al., 2013). Therefore, it is possible that cognitive changes make it more difficult for older adults to learn how to change their thinking particularly in the context of psychological therapy.

Purpose The purpose of this article is to review and discuss theories of working memory with special attention to their relevance to language processing. Method We begin with an overview of the concept of working memory itself and review some of the major theories. Then, we show how theories of working memory can be organized according to their stances on 3 major issues that distinguish them: modularity (on a continuum from domain-general to very modular), attention (on a continuum from automatic to completely attention demanding), and purpose (on a continuum from idiographic, or concerned with individual differences, to nomothetic, or concerned with group norms). We examine recent research that has a bearing on these distinctions. Results Our review shows important differences between working memory theories that can be described according to positions on the 3 continua just noted. Conclusion Once properly understood, working memory theories, methods, and data can serve as quite useful tools for language research.
