Background music as noise abatement in open‐plan offices: A laboratory study on performance effects and subjective preferences

Continuous noise is played in many open‐plan offices to partially mask ambient sounds, in particular background speech. With this, the detrimental impact of background sounds on cognitive performance is intended to be reduced as well as subjectively perceived disturbance. Our experiments explored whether background music can achieve the same effects. Besides collecting subjective rating data, we tested cognitive performance using verbal serial recall. This is the standard task for exploring verbal short‐term memory, which is central to human information processing. Either staccato music, legato music or continuous noise was superimposed on office noise. In Experiment 1 (N = 30), only continuous noise reduced the detrimental impact of office noise significantly. Legato music did not qualify in this respect although it did not diminish cognitive performance when presented in isolation in Experiment 2 (N = 20). Subjective ratings in both experiments revealed that most participants would prefer legato music to continuous noise in office environments. Copyright © 2008 John Wiley & Sons, Ltd.

Two- vs. three-dimensional presentation of mental rotation tasks: Sex differences and effects of training on performance and brain activation

The well-documented sex difference in mental rotation favoring males has been shown to emerge only for 2-dimensional presentations of 3-dimensional objects, but not with actual 3-dimensional objects or with virtual reality presentations of 3-dimensional objects. Training studies using computer games with mental rotation-related content have demonstrated training effects on mental rotation performance. Here, we studied the combined effect of a two-week mental rotation (MR) training on 2-dimensional vs. 3-dimensional presentations of a classic Shepard–Metzler task (presented in a pretest–training–posttest design) and their accompanying cortical activation patterns assessed via EEG in a sample of 38 male and 39 female adolescents of about 15 years of age. Analysis of one performance parameter (reaction times) displayed only main effects of dimensionality (with shorter RTs on the 3D vs. 2D version of the MR task) and of training (significant shortening of RTs), but no significant sex difference. Analysis of the other performance parameter (scores) in the MR task revealed a sex difference favoring males that first, appeared only in the 2D version, but not in the 3D version of the MR task and, secondly, diminished after training. Neurophysiologically we observed a complex sex × dimensionality × training × hemisphere interaction showing that the hypothesized decrease of brain activation (increase in neural efficiency) with training emerged for males in both 2D and 3D conditions, whereas for females this decrease was found only in the 3D but not with the 2D version of the MR task.     

Walking through doorways causes forgetting: environmental integration

Memory for objects declines when people move from one location to another (the location updating effect). However, it is unclear whether this is attributable to event model updating or to task demands. The focus here was on the degree of integration for probed-for information with the experienced environment. In prior research, the probes were verbal labels of visual objects. Experiment 1 assessed whether this was a consequence of an item-probe mismatch, as with transfer-appropriate processing. Visual probes were used to better coordinate what was seen with the nature of the memory probe. In Experiment 2, people received additional word pairs to remember, which were less well integrated with the environment, to assess whether the probed-for information needed to be well integrated. The results showed location updating effects in both cases. These data are consistent with an event cognition view that mental updating of a dynamic event disrupts memory.     

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.
