CAN COGNITIVE TRAINING USING A TABLET COMPUTER ENHANCE COGNITIVE FUNCTION OF HEALTHY OLDER ADULTS? AN ALTERNATING-TREATMENT DESIGN

Even though a variety of cognitive interventions have been conducted to ameliorate age-related cognitive declines, the effects of cognitive intervention using activities in everyday life are still unknown. The purpose of this study was to compare the effects between tablet computer-based productive and receptive cognitive engagement using an alternating-treatment design. Three healthy older adults performed a total of 19 sessions consisting of three baseline periods and 16 alternating training sessions. The training sessions were divided into four blocks and each block involved four treatment sessions. Productive and receptive engagements were randomly allocated to four treatment sessions. All participants alternatively received productive engagement that requires learning new practical applications and receptive engagement requiring little new learning such as listening to music. Prefrontal cortex (PFC) activity using functional near-infrared spectroscopy and executive function through the Trail Making Test were assessed at the baseline and the end of each session. All data were visually analyzed. Visual analysis results showed that the productive engagement was associated with higher PFC activity and faster performance in the Trail Making Test, compared to those utilizing receptive engagement. These results suggest that productive engagement might be effective in facilitating PFC activity and improving the executive function of healthy older adults, indicating cognitively challenging activities are more beneficial relative to nonchallenging activities.

Productive engagement and ageing in productivist welfare regimes: questing for an age-friendly city in Hong Kong

The population aged 65 years and above in Hong Kong is projected to rise from 15 per cent in 2014 to 38.4 per cent in 2069. Therefore, the quest for creating age-friendly conditions and the promotion of active ageing has become a priority for the Hong Kong Government and stakeholders in the city. Using a cross-national comparative framework for productive engagement in later life, this article examines the predictors of productive engagement (perceived voluntary engagement) in two districts (the Islands and Tsuen Wan) of Hong Kong – a typical productivist welfare regime in Asia. Data were collected through a social survey to ascertain the perception of an age-friendly city and active ageing in 2016 and 2018 from 1,638 persons aged 60 years and older. The results indicate some differences in the perception of the key determinants in both districts, but the factors associated with productive engagement were consistent, namely social atmosphere, social provisions and the built environment. The findings are discussed within the broader discourse on social gerontology, age-friendly cities and productivist welfare regimes.

Discursive psychology and feminism

This appraisal highlights the productive engagement between feminism and discursive psychology (DP). It discusses some of the confluence and tensions between DP and feminism. The two share critical perspectives on science and psychology, a concern with prejudice, and have ideas in common about the constructed nature of social categories, such as gender. One difficulty arises from the relativism associated with the post-structural theoretical underpinnings of DP, which can be understood as politically paralyzing. Another problem comes from an endorsement of a conversation analytic mentality, where identity categories such as gender can only be legitimately used in an analysis when participants' orient to their relevance. The high-profile debates and literature in DP shows it has made a notable contribution to social psychology and its influence can also be found in other areas. A particular influence of DP highlighted in the present appraisal is on gender and language research. © 2011 The British Psychological Society.

What if Social Robots Look for Productive Engagement?

In educational HRI, it is generally believed that a robots behavior has a direct effect on the engagement of a user with the robot, the task at hand and also their partner in case of a collaborative activity. Increasing this engagement is then held responsible for increased learning and productivity. The state of the art usually investigates the relationship between the behaviors of the robot and the engagement state of the user while assuming a linear relationship between engagement and the end goal: learning. However, is it correct to assume that to maximise learning, one needs to maximise engagement? Furthermore, conventional supervised models of engagement require human annotators to get labels. This is not only laborious but also introduces further subjectivity in an already subjective construct of engagement. Can we have machine-learning models for engagement detection where annotations do not rely on human annotators? Looking deeper at the behavioral patterns and the learning outcomes and a performance metric in a multi-modal data set collected in an educational human–human–robot setup with 68 students, we observe a hidden link that we term as Productive Engagement. We theorize a robot incorporating this knowledge will (1) distinguish teams based on engagement that is conducive of learning; and (2) adopt behaviors that eventually lead the users to increased learning by means of being productively engaged. Furthermore, this seminal link paves way for machine-learning models in educational HRI with automatic labelling based on the data.

Perceived Life Expectancy Predicts Time Investment in Productive Aging Activities: An Ecological Momentary Assessment Study

Objectives: Despite known benefits of productive aging, it is unclear what explains time allocation in productive activities. We investigated whether productive engagement in older people can be explained by their age, health, socioeconomic status, and perceived life expectancy in Hong Kong. Methods: We interviewed 390 community-dwelling older persons for their health and perceived life expectancy, followed by a 7-day ecological momentary assessment to record their activities. Results: A total of 366 participants who completed the study (age 75 ± 8.3 years; 79% women) reported an average perceived life expectancy of nearly 10 years. The majority (59%) engaged in productive activities. Estimates of the structural equation model (RMSEA = 0.046) showed that age and health were associated with productive engagement, mediated by perceived life expectancy. Discussion and Implications: Future efforts in promoting productive aging and related research should include interventions addressing perceived life expectancy, a potentially modifiable factor.

The Impact of Productive Engagement on BMI Classification in Middle Age and Later Life

Purpose: This study examines productive engagement among middle-age and older adults as a predictor of body mass classification over time, from a role theory perspective.] Methods: Longitudinal data (2010-2018) from the Health and Retirement Survey were analyzed using multinomial logistic regressions, with separate analyses for two age groups: middle-age (age 50-64; n=8,005) and older adults (age 65 and over; n=9,123). Results: For the middle-age sample, working more hours increased odds of being overweight, and more time spent caring for parents increased the odds of being obese. For older adults, informal volunteering decreased the odds of being underweight. For the most part, being in the obese category was predicted by health (more chronic conditions, worse self-rated health, less frequent vigorous exercise, and non-smoker status), and sociodemographic factors (lower earnings, lower education, Black race, and younger age) for both younger and older samples. Implications: The findings reinforce the benefits of public support for workplace wellness initiatives that promote healthy eating and exercise behaviors. Further, public funding could be used to support programs that promote informal volunteering for older adults could reduce the risks associated with being underweight, thus advancing social aims while promoting public health.

The Not-So-Strange Case of Dr. Jekyll and Mr. Hyde in Antibiotic Research: An Interdisciplinary Opportunity

Literary-rhetorical devices like figurative language and analogy can help explain concepts that exceed our capacity to grasp intuitively. It is not surprising these devices are used to discuss virulence, pathogenesis, and antibiotics. Allusions to Robert Louis Stevenson’s Strange Case of Dr. Jekyll and Mr. Hyde seem to be used with particular frequency in research pertaining to pathogens, especially in studies contemporary with our evolving understanding of antibiotic resistance. More recent references to the text have appeared in research parsing definitions of virulence and acknowledging the role of anti-virulence in future therapeutics. While it is obvious that scientists invoke Stevenson’s story for stylistic purposes, its use could go beyond the stylistic—and might even generate rhetorical and imaginative possibilities for framing research. This perspective discusses the first published allusion to Jekyll and Hyde in reference to virulence and pathogenesis; comments on a select number of specific instances of Jekyll and Hyde in contemporary scientific literature; briefly contextualizes the novel; and concludes with the implications of a more productive engagement with humanistic disciplines in the face of antibiotic resistance.
