Listening to music before, during, or after sports is a common phenomenon, yet its functions and effects on performance, cognition, and behavior remain to be investigated. In this study we present a novel approach to the role of music in sports and exercise that focuses on the notion of musical self-enhancement (Elvers, 2016). We derived the following hypotheses from this framework: listening to motivational music will (i) enhance self-evaluative cognition, (ii) improve performance in a ball game, and (iii) evoke greater risk-taking behavior. To evaluate the hypotheses, we conducted a between-groups experiment (N = 150) testing the effectiveness of both an experimenter playlist and a participant-selected playlist in comparison to a no-music control condition. All participants performed a ball-throwing task developed by Decharms and Dav{\´e} (1965), consisting of two parts: First, participants threw the ball from fixed distances into a funnel basket. During this task, performance was measured. In the second part, the participants themselves chose distances from the basket, which allowed their risk-taking behavior to be assessed. The results indicate that listening to motivational music led to greater risk taking but did not improve ball-throwing performance. This effect was more pronounced in male participants and among those who listened to their own playlists. Furthermore, self-selected music enhanced state self-esteem in participants who were performing well but not in those who were performing poorly. We also discuss further implications for the notion of musical self-enhancement. // Listening to music before, during, or after sports is a common phenomenon, yet its functions and effects on performance, cognition, and behavior remain to be investigated.

Until now, little has been written about the processes underlying the selection of music in daily life. The present study aimed to disentangle some of the complex processes among the listener, situation, and functions of music listening involved in music selection. Utilizing the experience sampling method, data were collected from 119 participants using a smartphone application. For 10 consecutive days, participants received 14 prompts using stratified-random sampling throughout the day and reported on their music-listening behavior. Statistical learning procedures on multilevel regression models and multilevel structural equation modeling were used to determine the most important predictors and analyze mediation processes between person, situation, functions of listening, and music selection. Results revealed that the features of music selected in daily life were predominantly determined by situational characteristics, whereas consistent individual differences were of minor importance. Functions of music listening were found to act as a mediator between characteristics of the situation and music-selection behavior. We further observed several significant random effects, which indicated that individuals differed in how situational variables affected their music selection behavior. Our findings suggest a need to shift the focus of music-listening research from individual differences to situational influences, including potential person-situation interactions.}, language = {en} } @article{LuizardSteffensWeinzierl2020, author = {Luizard, Paul and Steffens, Jochen and Weinzierl, Stefan}, title = {Singing in different rooms: Common or individual adaptation patterns to the acoustic conditions?}, series = {The Journal of the Acoustical Society of America}, volume = {147}, journal = {The Journal of the Acoustical Society of America}, number = {2}, publisher = {ASA}, doi = {10.1121/10.0000715}, year = {2020}, language = {en} } @article{SchittkowskiRulandLaudenschlegeretal.2018, author = {Schittkowski, Julian and Ruland, Holger and Laudenschleger, Daniel and Girod, Kai and K{\"a}hler, Kevin and Kaluza, Stefan and Muhler, Martin and Schl{\"o}gl, Robert}, title = {Methanol Synthesis from Steel Mill Exhaust Gases: Challenges for the Industrial Cu/ZnO/Al 2 O 3 Catalyst}, series = {Chemie Ingenieur Technik}, volume = {90}, journal = {Chemie Ingenieur Technik}, number = {10}, publisher = {Wiley}, issn = {1522-2640}, doi = {10.1002/cite.201800017}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-34526}, pages = {1419 -- 1429}, year = {2018}, language = {en} } @article{UnterfraunerVoigtHofer2021, author = {Unterfrauner, Elisabeth and Voigt, Christian and Hofer, Margit}, title = {The effect of maker and entrepreneurial education on self-efficacy and creativity}, series = {Entrepreneurship Education}, volume = {4}, journal = {Entrepreneurship Education}, number = {4}, publisher = {Springer Nature}, issn = {2520-8152}, doi = {10.1007/s41959-021-00060-w}, pages = {403 -- 424}, year = {2021}, language = {en} } @article{UnterfraunerVoigt2017, author = {Unterfrauner, Elisabeth and Voigt, Christian}, title = {Makers' ambitions to do socially valuable things}, series = {The Design Journal}, volume = {20}, journal = {The Design Journal}, number = {sup1}, publisher = {Taylor \& Francis}, issn = {1756-3062}, doi = {10.1080/14606925.2017.1352835}, pages = {3317 -- 3325}, year = {2017}, language = {en} } @article{SeebacherVanaVoigtetal.2021, author = {Seebacher, Lisa M. and Vana, Irina and Voigt, Christian and Tschank, Juliet}, title = {Is Science for Everyone?

The structure and composition of the material was characterized via powder X-ray diffraction (PXRD), M{\"o}ssbauer spectroscopy (MB), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and energy dispersive X-ray spectroscopy (EDX). Two preparation methods of pentlandite bulk electrodes are presented. In the first approach a piece of synthetic pentlandite rock is directly contacted via a wire ferrule. The second approach utilizes pentlandite pellets, pressed from finely ground powder, which is immobilized in a Teflon casing. Both electrodes, whilst being prepared by an additive-free method, reveal high durability during electrocatalytic conversions in comparison to common drop-coating methods. We herein showcase the striking performance of such electrodes to accomplish the hydrogen evolution reaction (HER) and present a standardized method to evaluate the electrocatalytic performance by electrochemical and gas chromatographic methods. Furthermore, we report stability tests via potentiostatic methods at an overpotential of 0.6 V to explore the material limitations of the electrodes during electrolysis under industrial relevant conditions.}, language = {en} }
