The neural processing of speech and music is still a matter of debate. A long tradition that assumes shared processing capacities for the two domains contrasts with views that assume domain-specific processing. We here contribute to this topic by investigating, in a functional magnetic imaging (fMRI) study, ecologically valid stimuli that are identical in wording and differ only in that one group is typically spoken (or silently read), whereas the other is sung: poems and their respective musical settings.

Article Synopsis
  • Executive function (EF) and effortful control (EC) are closely related concepts that both involve self-regulation but stem from different research backgrounds—EF from neurocognitive studies and EC from temperament research.
  • A study involving 88 preschool-aged children aimed to analyze the relationship between EF and EC by using specific assessments for each construct, including parent questionnaires on their children's behavior.
  • Results indicated significant correlations between EF and EC, leading to the conclusion that these two constructs are highly similar and suggest a unified model of self-regulation in preschoolers.

Institute for Mechatronics, University of Innsbruck, Technikerstraße 13, 6020, Innsbruck, Austria; Laboratory for Manufacturing Technology, Helmut-Schmidt-University/University of the Federal Armed Forces Hamburg, Holstenhofweg 85, 22043, Hamburg, Germany. Electronic address:

This study investigated the pressures occurring within the arm human-machine-interfaces (HMI) of four different exoskeletons that support static and dynamic work at or above head level, and the effects of the HMI on neurovascular supply of the upper extremity using an orthopedic provocation maneuver with raised arms with and without the exoskeletons. Decreased time in the provocation maneuver with exoskeletons indicated a negative effect of the HMIs on the vascular and neural supply of the arm. Average pressure in the static situation was 3.

In modern times, the collaboration between humans and machines increasingly rises, combining their respective benefits. The direct physical support causes interaction forces in human-machine interfaces, whereas their form determines both the effectiveness and comfort of the collaboration. However, their correct detection requires various sensor characteristics and remains challenging.

The COVID-19 pandemic has had a great impact on school learning so far, creating a new and potentially stressful situation during school closures for teachers and students. The sudden switch to distance learning might have been especially hard to cope with for students with special educational needs (SEN). Teachers of student with SEN might thus face greater obstacles when establishing and dealing with distance learning.

Background: The legal and ethical guidelines of psychological professional associations stipulate that informed consent by patients is an essential prerequisite for psychotherapy. Despite this awareness of the importance of informed consent, there is little empirical evidence on what psychotherapists' attitudes towards informed consent are and how informed consent is implemented in psychotherapeutic practice.

Methods: 155 psychotherapists in Switzerland completed an online survey assessing their attitudes regarding informed consent.

Human research has shown interactions between rewards and cognitive control. In animal models of affective neuroscience, reward administration typically involves administering orosensory sugar signals (OSS) during caloric-deprived states. We adopted this procedure to investigate neurophysiological mechanisms of reward-cognitive control interactions in humans.

Background: Aesthetic experiences elicit a wide range of positive emotions and have a positive impact on various health outcomes. In this context, savoring refers to a cognitive form of emotion regulation used to maintain and extend positive emotional experiences and is considered to contribute to health and well-being. Chronic pain has been linked to reduced reward-seeking behavior.

Do we savour aesthetic experiences less when distracted by interrupted tasks, work rumination, or stress? Evidence suggests that the ability to concentrate on the aesthetic experience is crucial for initiating a processing mode of conscious aesthetic reception that results in more positive emotions. When working memory resources are otherwise occupied, people are less able to concentrate on aesthetic experiences. Aesthetic savouring, in particular-a cognitive form of emotion regulation that is used to maintain and extend aesthetic experiences-is thought to be impaired under those circumstances.

Methodologies for evaluating exoskeletons with industrial applications.

Ergonomics

February 2022

Department of Production Technologies, Institute of Mechatronics, University of Innsbruck, Innsbruck, Austria.

Industrial exoskeletons are globally developed, explored, and increasingly implemented in industrial workplaces. Multiple technical, physical, and psychological aspects should be assessed prior to their daily application in various occupational environments. The methodology for evaluating these aspects is not standardised and differs in terms of focussed research objectives, used types of analyses, applied testing procedures, and use cases.

While body modifications have increasingly gained acceptance and popularity, how different subpopulations aesthetically appreciate tattoos remains unclear. The present study aimed to investigate the conceptual structure underlying tattoo aesthetics, focusing on the effects of internalized social norms and expertise. Using a timed free-listing task, three groups (≤49 years, ≥50 years, and experts) comprising 497 participants were asked to write down adjectives that could describe tattoo aesthetics.

Debt Relief as a Last Resort for the Lender of Last Resort?: Monetary Financing - Doing It Right.

Inter Econ

August 2021

University of the Federal Armed Forces Hamburg, Helmut Schmidt University, Holstenhofweg 85, 22043 Hamburg, Germany.

The coronavirus crisis has led to a sharp increase in the debt-to-GDP ratios of the euro area member states. Without external support, access to the capital market could be seriously threatened in the medium term for Italy, but also for other member states. While the Pandemic Emergency Purchase Programme, which is designed as a monetary policy instrument, is regarded by some as a violation of the prohibition of monetary financing, the Next Generation EU recovery fund is likely to direct the fundamental structures of the European Union towards a fiscal union with considerable redistribution elements.

Although statistical regularities in the environment often go explicitly unnoticed, traces of implicit learning are evident in our neural activity. Recent perspectives have offered evidence that both pre-stimulus oscillations and peri-stimulus event-related potentials are reliable biomarkers of implicit expectations arising from statistical learning. What remains ambiguous, however, is the origination and development of these implicit expectations.

Aesthetic emotions are elicited by different sensory impressions generated by music, visual arts, literature, theater, film, or nature scenes. Recently, the AESTHEMOS scale has been developed to facilitate the empirical assessment of such emotions. In this article we report a semantic profile analysis of aesthetic emotion terms that had been used for the development of this scale, using the GRID approach.

The congruency sequence effect (CSE) describes the performance difference of congruent trials (in which target and distractor stimuli are associated with the same response) compared to incongruent trials (in which target and distractor stimuli are associated with different responses) as a function of the preceding congruency level (congruent trials relative to incongruent trials). The CSE is commonly interpreted as a measure of conflict-induced attentional adjustment. Although previous research has made substantial progress aiming at controlling for alternative explanations of the CSE, both task-specific and fundamental confounds have remained.
