Greater Intermanual Transfer in the Elderly Suggests Age-Related Bilateral Motor Cortex Activation Is Compensatory

ABSTRACT. Hemispheric lateralization of movement control diminishes with age; whether this is compensatory or maladaptive is debated. The authors hypothesized that if compensatory, bilateral activation would lead to greater intermanual transfer in older subjects learning tasks that activate the cortex unilaterally in young adults. They studied 10 young and 14 older subjects, learning a unimanual visuomotor task comprising a feedforward phase, where there is unilateral cortical activation in young adults, and a feedback phase, which activates the cortex bilaterally in both age groups. Increased intermanual transfer was demonstrated in older subjects during feedforward learning, with no difference between groups during feedback learning. This finding is consistent with bilateral cortical activation being compensatory to maintain performance despite declining computational efficiency in neural networks.     

Between acculturation and self-assertion: individualisation in the German-Jewish context of the German Empire and the Weimar Republic and its contribution to the development of modern sociology

Abstract

Using the example of four German-Jewish scholars of the 19^th and 20^th centuries – Moritz Lazarus (1824–1903), Hermann Cohen (1842–1918), Georg Simmel (1858–1918) and Alfred Schütz (1899–1959), who all maintained intense connections to their Jewish backgrounds – this article aims to illustrate that Jewish traditions held favourable conditions for processes of religious and social individualisation. The focus of the analysis is placed on the figure of the stranger, a theme all four authors dealt with in their work. On the one hand they investigated the stranger as a biblical figure with social-ethical implications (Lazarus and Cohen); on the other, they developed a sociological approach by analysing the role of the stranger in the construction of society (Schütz and Simmel). This article strives to illustrate how a particular religious ideal – the commandment of love for one's neighbour and the recognition of the stranger as a fellowman – has been transformed into a sociological concept for the promotion of individuality. Reconstructing this context also means exploring the history of sociology as a scientific discipline in Germany and to look into the attempts of sociologists to understand otherness in the multicultural societies of the 21st century.     

The relevance of sleep and circadian misalignment for procrastination among shift workers

This daily diary study contributes to current research uncovering the role of sleep for employees’ effective self‐regulation at work. We focus on shift workers’ effective self‐regulation in terms of their general and day‐specific inclination to procrastinate, that is, their tendency to delay the initiation or completion of work activities. We hypothesized that transitory sleep characteristics (day‐specific sleep quality and sleep duration) and chronic sleep characteristics in terms of circadian misalignment are relevant for procrastination. Sixty‐six shift workers completed two daily questionnaires over the course of one work week, resulting in 332 days of analysis. Results of multilevel regression analyses showed that on days when shift workers slept better and longer—compared to days when they slept worse and shorter—they had more energy and willpower available after sleep and subsequently were less prone to procrastination. Moreover, the more work times (permanent shift) were misaligned with employees’ sleep–wake preferences (chronotype) the more pronounced was shift workers’ inclination to procrastinate at work. The present findings provide important implications for shift workers’ effective functioning at work.

Practitioner Points

• To promote shift workers’ effective functioning at work, when scheduling shift work, circadian principles should be taken into account, and work times should be aligned with workers’ chronotypes.
• Day‐specific sleep quality and duration co‐vary with procrastination at work. Thus, on days on which procrastination would be especially harmful, sleep of good quality and of sufficient duration should be obtained.

     

What makes for a good break? A diary study on recovery experiences during lunch break

This study investigated the role of four recovery experiences during lunch break for employees’ afternoon well‐being. We hypothesized that lunch‐break recovery experiences (psychological detachment, relaxation, control, and relatedness) reduce afternoon exhaustion and enhance afternoon work engagement via replenished personal resources (i.e., state of being recovered immediately after break and subsequent self‐efficacy regarding the upcoming tasks in the afternoon). One hundred and nine employees provided daily survey data three times a day (i.e., start of work, after lunch break, end of work) over a period of two workweeks. Multilevel path analysis showed that relaxation, control, and relatedness during lunch break negatively predicted afternoon exhaustion and positively predicted afternoon work engagement via state of being recovered. For relaxation and relatedness, we additionally found positive serial indirect effects on afternoon work engagement via state of being recovered and self‐efficacy. Psychological detachment was not related to personal resources and afternoon well‐being. This study demonstrates that experiencing control over lunch break and using the lunch break to relax and to relate to others are indirectly associated with improved afternoon well‐being via replenished personal resources.

Practitioner points

• Relaxation, control, and relatedness constitute lunch‐break recovery experiences that indirectly foster feeling confident, replenished, and engaged in the afternoon.
• Employees should strive to spend their lunch breaks in ways that help them feel relaxed, related, and in control.
• Organizations should provide their employees with sufficient break control and offer environments that facilitate relaxation and socializing during lunch break.

     

Differential changes in the development of motor coordination and executive functions in children with motor coordination impairments

Cognitive and motor coordination skills of children with and without motor coordination impairments were examined with a one-year follow-up investigation. Initially, children were between 4 and 6 years old. Age-appropriate tests of executive functions (updating, switching, inhibition, interference control), motor coordination (the Movement Assessment Battery for Children-2) and fitness (the Körperkoordinations-Test für Kinder) were administered in two consecutive years. Several background variables (age, socioeconomic status, medical support, clinical interventions, leisure activities) and potential moderators (nonverbal intelligence, reaction time, visual perception) were controlled. The matched sample consisted of 48 control children and 48 children with motor coordination impairments. The children’s executive functions dramatically improved during the one-year period. With regard to motor coordination performance, half of the impaired children caught up to the control children’s level (“remission group”), while the remaining half showed no improvement (“persisting group”). Compared to the persisting group, the children in the remission group showed markedly better interference control at both measurement points. The correlation between executive functions and motor coordination is significant in the persisting group, but not in the remission group. The results of the study are discussed in the light of the role of executive functions, especially inhibition processes, for the automatization of motor coordination tasks.     

Party Pooper or Life of the Party: Dampening and Enhancing of Positive Affect in a Peer Context

Dampening and enhancing responses to positive affect have been linked to depressive symptoms. The main aim of the present study was to examine such responses in an interpersonal peer context and to examine their relation with depressive symptoms. A community sample of 665 seventh-graders (52.0% girls, Mage = 12.7 years) took part in the study. Using a newly developed questionnaire, the Co-Dampening and Co-Enhancing Questionnaire (CoDEQ), a two-factor model distinguishing co-dampening and co-enhancing was validated. Relations with general depressive symptoms, anhedonic symptoms, and friendship quality were investigated. The direction of relations was examined over a 1-year interval using cross-lagged analyses. Cross-sectional results revealed that higher levels of co-dampening and lower levels of co-enhancing were associated with more depressive and anhedonic symptoms, while controlling for co-rumination levels. For anhedonic symptoms, this pattern also held over and above intrapersonal dampening and enhancing. Friendship quality was related to higher concurrent levels of co-enhancing and lower levels of co-dampening. The longitudinal results pointed towards a scar model, in that both depressive and anhedonic symptoms predicted relative increases in co-dampening over time; however, this did not hold in a model in which dampening and enhancing were included as control variables.

The Role of Art in Emotional-Moral Reflection on Risky and Controversial Technologies: the Case of BNCI

In this article, we explore the role that art can play in ethical reflection on risky and controversial technologies. New technologies often give rise to societal controversies about their potential risks and benefits. Over the last decades, social scientists, psychologists, and philosophers have criticized quantitative approaches to risk on the grounds that they oversimplify its societal and ethical implications. There is broad consensus amongst these scholars that stakeholders and their values and concerns should be included in decision-making about technological risks. It has also been argued that the emotional responses of people can shed important light on the ethical aspects of risk and uncertainty. However, people’s emotions can be narrowly focused and biased. This article therefore assesses the role that technology-inspired artworks can play in overcoming such biases, by challenging our imagination and providing us with different perspectives on possible technological developments and their implications for society. Philosophers have not yet studied such artworks, so this constitutes an entirely new field of research for scholars of risk and moral theory. In particular, we focus on the case of BNCI (Brain/Neural Computer Interface) technologies and related artworks. These technologies and artworks touch on questions of what it means to be human, thereby raising profound ethical and philosophical challenges. We discuss the experiences of artists, scientists, and engineers who are directly involved with BNCI technologies, and who were interviewed during a Hackathon at Amsterdam’s Waag Society in June 2016. Their views are analyzed in light of philosophical and aesthetic theories, which allows us to consider relevant ethical and conceptual issues as well as topics for further investigation.
