Digital tools can support focusing on meaningful tasks with features like time tracking, feedback, or rewards. Evidence exists for benefits regarding behavioral focus, distraction management, and motivation, but also for hesitation to use digital support at all. Building on the Unified Theory of Acceptance and Use of Technology (UTAUT), this research explores which factors can foster or hinder the intention to use an exemplary software to support self-regulation.\r\nMethods\r\nA sample of 96 adult volunteers watched a short introductory video explaining how the software focUS fosters self-regulated studying and working. Subsequently, participants completed an online survey to capture their willingness to use focUS, expected gains and challenges, and individual characteristics.\r\nResults\r\nParticipants expressed stronger intentions to use focUS when they expected increased benefits in performance. By trend, lower levels of expected effort also hinted on stronger intentions to use focUS. Contrary to expectations, participants lacking previous experience with software in the scope described, who anticipated higher effort when using focUS, tended to express stronger intentions to use it.\r\nDiscussion\r\nTaken together, our evidence suggests that highlighting specific performance improvements may encourage the use of digital support for tasks that require self-regulation. Ensuring the use of digital support to be as effortless as possible could provide yet another compelling argument to use it. Particularly for inexperienced users, sparking curiosity for the challenges of the unknown might be a worthwhile strategy to reduce hesitation towards emerging technologies.","annote":"","author":[{"family":"Wirzberger","given":"Maria"},{"family":"Bareiß","given":"Laura"},{"family":"Herbst","given":"Veronika"},{"family":"Stock","given":"Adrian"},{"family":"Kembitzky","given":"Jule"}],"citation-label":"wirzberger2025performance","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Acta Psychologica","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2025"]],"literal":"2025"},"event-place":"","id":"10e791a85e2b9de0d19f27ca7c09b69dmariawirzberger","interhash":"aa0c7aa833c1f78085582a4ea6384eda","intrahash":"10e791a85e2b9de0d19f27ca7c09b69d","issue":"","issued":{"date-parts":[["2025"]],"literal":"2025"},"keyword":"myown learning technology performance effort digital feedback UTAUT acceptance academic self-regulation working expectancy","misc":{"doi":"https://doi.org/10.1016/j.actpsy.2025.105273"},"note":"","number":"","page":"105273","page-first":"105273","publisher":"Elsevier","publisher-place":"","status":"","title":"Performance expectancy benefits acceptance towards digital support for self-regulation","type":"article-journal","username":"mariawirzberger","version":"","volume":"258"},"e0eb12714cb5e8c70bc4ef13a3f70c30inspo5":{"DOI":"10.1113/jp287508","ISBN":"","ISSN":"1469-7793","URL":"http://dx.doi.org/10.1113/JP287508","abstract":"It is unclear whether cortical and spinal excitability modulations contribute to enhanced stretch–shortening cycle (SSC) performance. Therefore, this study investigated cortical and spinal excitability modulations during and following shortening of SSC contractions compared with pure shortening (SHO) contractions. Participants (n = 18) performed submaximal voluntary plantar flexion contractions while prone on the dynamometer bench. The right foot was strapped onto the dynamometer's footplate attachment, and the resultant ankle joint torque and crank arm angle were recorded. Cortical and spinal excitability modulations of the soleus muscle were analysed by eliciting compound muscle actional potentials via electrical nerve stimulation, cervicomedullary motor-evoked potentials (CMEPs) via electrical stimulation of the spinal cord, and motor-evoked potentials (MEPs) via magnetic stimulation of the motor cortex. Mean torque following stretch was significantly increased by 7 ± 3% (P = 0.029) compared with the fixed-end reference (REF) contraction, and mean torque during shortening of SSC compared with SHO was significantly increased by 12 ± 24% (P = 0.046). Mean steady-state torque was significantly lower by 13 ± 3% (P = 0.006) and 9 ± 12% (P = 0.011) following SSC compared with REF and SHO, respectively. Mean steady-state torque was not significantly different following SHO compared with REF (7 ± 8%, P = 0.456). CMEPs and MEPs were also not significantly different during shortening of SSC compared with SHO (P ≥ 0.885) or during the steady state of SSC, SHO and REF (P ≥ 0.727). Therefore, our results indicate that SSC performance was not associated with cortical or spinal excitability modulations during or after shortening, but rather driven by mechanical mechanisms triggered during active stretch.","annote":"","author":[{"family":"Rissmann","given":"Lea‐Fedia"},{"family":"Raiteri","given":"Brent James"},{"family":"Seiberl","given":"Wolfgang"},{"family":"Siebert","given":"Tobias"},{"family":"Hahn","given":"Daniel"}],"citation-label":"Rissmann_2025","collection-editor":[],"collection-title":"","container-author":[],"container-title":"The Journal of Physiology","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2025","06"]],"literal":"2025"},"event-place":"","id":"e0eb12714cb5e8c70bc4ef13a3f70c30inspo5","interhash":"40953d65f08f042d8f840b9b2462a29b","intrahash":"e0eb12714cb5e8c70bc4ef13a3f70c30","issue":"","issued":{"date-parts":[["2025","06"]],"literal":"2025"},"keyword":"stretch epression surae force performance enhancement reflex triceps","misc":{"issn":"1469-7793","doi":"10.1113/jp287508"},"note":"","number":"","page":"","page-first":"","publisher":"Wiley","publisher-place":"","status":"","title":"The stretch–shortening cycle effect is not associated with cortical or spinal excitability modulations","type":"article-journal","username":"inspo5","version":"","volume":""},"e8ebd2f42b453167d2065725486828cbvancraen":{"DOI":"10.1145/3648115.3648130","ISBN":"9798400717901","ISSN":"","URL":"https://doi.org/10.1145/3648115.3648130","abstract":"SYCL provides programmers with four, and in the case of AdaptiveCpp even five, ways for calling and writing a device kernel.

Brain activation patterns revealed a cross-over interaction indicating workload-dependent left hemispheric inhibition processes during negative distractions and high workload.

Furthermore, we found a workload-independent negativity bias for neutral distractions, showing brain activation patterns similar to those of negative distractions.\r\nDiscussion\r\nIn conclusion, lateralized hemispheric processing, regulating emotional speech distractions and integrating emotional and cognitive processes, is influenced by workload levels and stimulus characteristics. These findings advance our understanding of the factors modulating hemispheric asymmetries during the processing and inhibition of emotional distractions, as well as the interplay between emotion and cognition. Moreover, they emphasize the significance of exploring emotion-cognition interactions in more naturalistic settings to gain a deeper understanding of their implications in real-world application scenarios (e.g., working and learning environments).","annote":"","author":[{"family":"Lingelbach","given":"Katharina"},{"family":"Gado","given":"Sabrina"},{"family":"Wirzberger","given":"Maria"},{"family":"Vukelic","given":"Mathias"}],"citation-label":"lingelbach2024workloaddependent","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Frontiers in Neuroergonomics","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2023"]],"literal":"2023"},"event-place":"","id":"0bf5204692e1ba405c3d3bcc99c756b4mariawirzberger","interhash":"624fe12bf6b88562c04d7d5eabb39c6a","intrahash":"0bf5204692e1ba405c3d3bcc99c756b4","issue":"","issued":{"date-parts":[["2023"]],"literal":"2023"},"keyword":"fNIRS myown emotion cognition simulation workload llis performance","misc":{"doi":"https://doi.org/10.3389/fnrgo.2023.1273810"},"note":"","number":"","page":"1273810","page-first":"1273810","publisher":"","publisher-place":"","status":"","title":"Workload-dependent hemispheric asymmetries during the emotion-cognition interaction: a close-to-naturalistic fNIRS study","type":"article-journal","username":"mariawirzberger","version":"","volume":"4"},"dc5e87ac6cadb3ad626aa77c570d0aa8mariawirzberger":{"DOI":"10.1016/j.chbr.2023.100364","ISBN":"","ISSN":"2451-9588","URL":"http://dx.doi.org/10.1016/j.chbr.2023.100364","abstract":"","annote":"","author":[{"family":"Schmitz-Hübsch","given":"Alina"},{"family":"Becker","given":"Ron"},{"family":"Wirzberger","given":"Maria"}],"citation-label":"Schmitz_H_bsch_2024","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Computers in Human Behavior Reports","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2024","03"]],"literal":"2024"},"event-place":"","id":"dc5e87ac6cadb3ad626aa77c570d0aa8mariawirzberger","interhash":"285ed0cb1e3acc8a46f7066af6ac02af","intrahash":"dc5e87ac6cadb3ad626aa77c570d0aa8","issue":"","issued":{"date-parts":[["2024","03"]],"literal":"2024"},"keyword":"myown emotion HMI cognition simulation llis performance","misc":{"issn":"2451-9588","doi":"10.1016/j.chbr.2023.100364"},"note":"","number":"","page":"100364","page-first":"100364","publisher":"Elsevier BV","publisher-place":"","status":"","title":"Emotion-performance relationship in safety-critical human-machine systems","type":"article-journal","username":"mariawirzberger","version":"","volume":"13"},"d4e5455f2ff303085c578af509d79b48mariawirzberger":{"DOI":"10.1007/s11218-023-09833-8","ISBN":"","ISSN":"1573-1928","URL":"https://doi.org/10.1007/s11218-023-09833-8","abstract":"Stereotypical assumptions associating high levels of giftedness and outstanding performance with maladaptive behavioral characteristics and personality traits (cf. disharmony stereotype) are rather prevalent in the school context as well as in the musical domain. Such preconceptions among teachers can influence student assessment and corresponding performance expectations, which might, in turn, impact future lesson planning. In an experiment using a controlled vignette approach, the current study, with Nþinspace=þinspace211 (prospective) German music school teachers, investigated how background information, combined with a manipulated music recording, affected (prospective) music school teachers' assessment of a fictive student's performance, behavioral characteristics, personality traits, and teachers'  consequential lesson planning. Experimental variations included the fictive student's supposed level of giftedness, social interaction, age, and duration of instrumental lessons. Results indicated that music school teachers' preconceptions of students assumed to be musically gifted were a high level of intellectual and musical abilities with behavioral characteristics and personality traits rated at least equivalent to those of students assumed to have average giftedness. Teachers' lesson planning was not influenced by any of the manipulated background information. Taken together, the observed pattern of effects contradicts the disharmony stereotype but tends to align more with the harmony stereotype as music school teachers' prevailing preconceptions about students supposed to be musically gifted.","annote":"","author":[{"family":"Bareiß","given":"Laura"},{"family":"Platz","given":"Friedrich"},{"family":"Wirzberger","given":"Maria"}],"citation-label":"Bareiß2024","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Social Psychology of Education","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2023","06","01"]],"literal":"2023"},"event-place":"","id":"d4e5455f2ff303085c578af509d79b48mariawirzberger","interhash":"1e0ffa9d0cd18bf769a0ec252a115ebc","intrahash":"d4e5455f2ff303085c578af509d79b48","issue":"3","issued":{"date-parts":[["2023","06","01"]],"literal":"2023"},"keyword":"teacher myown giftedness instruction cognition personality stereotype llis performance behavior","misc":{"issn":"1573-1928","doi":"10.1007/s11218-023-09833-8"},"note":"","number":"3","number-of-pages":"32","page":"1009--1041","page-first":"1009","publisher":"","publisher-place":"","status":"","title":"Implicit assumptions of (prospective) music school teachers about musically gifted students","type":"article-journal","username":"mariawirzberger","version":"","volume":"27"},"c7b1b5c04506bbf7cc3e680338a7928amariawirzberger":{"DOI":"10.1080/00140139.2024.2370440","ISBN":"","ISSN":"1366-5847","URL":"http://dx.doi.org/10.1080/00140139.2024.2370440","abstract":"","annote":"","author":[{"family":"Schmitz-Hübsch","given":"Alina"},{"family":"Gruber","given":"M.

In tutoring systems for safety-critical work environments, students are trained to achieve and maintain high performance, therefore an ATS should be capable of identifying critical emotional states hindering performance. Interindividual differences in the emotion-performance-relationship can be considered by using the ARC categorization system. The present contribution aims at developing a questionnaire-based method of classifying new learners to the categories. To that end, we investigated differences in personality traits between the different categories. In an airspace surveillance task, we measured performance, emotional valence, emotional arousal, and personality traits in N = 50 subjects. Results showed that a positive valence-performance-relationship, compared to a negative valence-performance-relationship, is associated with higher Neuroticism, lower Conscientiousness, and lower Openness to experience. There were no significant differences in the traits Agreeableness and Extraversion. Based on these results, a future ATS for safety-critical work environments could classify new learners in the ARCs using self-report data and thus dispense with physiological sensors. Thereby, user state diagnosis and evaluation for high performance is possible, setting the ground for an ATS adapting to critical emotional learner states.","annote":"","author":[{"family":"Schmitz-Hübsch","given":"Alina"},{"family":"Becker","given":"Ron"},{"family":"Wirzberger","given":"Maria"}],"citation-label":"schmitzhubsch2023personality","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Adaptive Instructional Systems.

This increase in performance is known as the stretch-shortening cycle (SSC)-effect. Recent findings demonstrate that the SSC-effect is present in the sarcomere itself. More recently, it has been suggested that cross-bridge (XB) kinetics and non-cross-bridge (non-XB) structures (e.g., titin and nebulin) contribute to the SSC-effect. As XBs and non-XB structures are characterized by a velocity dependence, we investigated the impact of stretch-shortening velocity on the SSC-effect. Accordingly, we performed in vitro isovelocity ramp experiments with varying ramp velocities (30, 60, and 85% of maximum contraction velocity for both stretch and shortening) and constant stretch-shortening magnitudes (17% of the optimum sarcomere length) using single skinned fibers of rat soleus muscles. The different contributions of XB and non-XB structures to force production were identified using the XB-inhibitor Blebbistatin. We show that (i) the SSC-effect is velocity-dependent—since the power output increases with increasing SSC-velocity. (ii) The energy recovery (ratio of elastic energy storage and release in the SSC) is higher in the Blebbistatin condition compared with the control condition. The stored and released energy in the Blebbistatin condition can be explained by the viscoelastic properties of the non-XB structure titin. Consequently, our experimental findings suggest that the energy stored in titin during the eccentric phase contributes to the SSC-effect in a velocity-dependent manner.","annote":"","author":[{"family":"Tomalka","given":"André"},{"family":"Weidner","given":"Sven"},{"family":"Hahn","given":"Daniel"},{"family":"Seiberl","given":"Wolfgang"},{"family":"Siebert","given":"Tobias"}],"citation-label":"Tomalka_2021","collection-editor":[],"collection-title":"","container-author":[],"container-title":"Frontiers in Physiology","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2021","03"]],"literal":"2021"},"event-place":"","id":"61fedf1d36ba0727ea70b4ebe0ccf080inspo5","interhash":"2c45e90e696b09a75331acf51aae74e4","intrahash":"61fedf1d36ba0727ea70b4ebe0ccf080","issue":"","issued":{"date-parts":[["2021","03"]],"literal":"2021"},"keyword":"contractile mechanical damping enhancement performance contractions stretch shortening PN2A-1 muscle power eccentric behavior","misc":{"doi":"https://doi.org/10.3389/fphys.2021.644981"},"note":"","number":"","page":"","page-first":"","publisher":"Frontiers Media SA","publisher-place":"","status":"","title":"Power Amplification Increases With Contraction Velocity During Stretch-Shortening Cycles of Skinned Muscle Fibers","type":"article-journal","username":"inspo5","version":"","volume":"12"},"cb291e05a1a3bbb91a404b35dfb148a0tpollinger":{"DOI":"10.1109/IPDPSW52791.2021.00066","ISBN":"","ISSN":"","URL":"","abstract":"Between a widening range of GPU vendors and the trend of having more GPUs per compute node in supercomputers such as Summit, Perlmutter, Frontier and Aurora, developing performant yet portable distributed HPC applications becomes ever more challenging. Leveraging existing solutions like Kokkos for platform-independent code and HPX for distributing the application in a task-based fashion can alleviate these challenges. However, using such frameworks in the same application requires them to work together seamlessly. In this work we present an HPX Kokkos integration that works both ways: we can integrate CPU and GPU Kokkos kernels as HPX tasks and inversely use HPX worker threads to work on Kokkos kernels. Using HPX futures makes launching and synchronizing Kokkos kernels from multiple threads easy, allowing us to move away from the more traditional fork-join model. To evaluate our integrations we ported existing Vc and CUDA kernels within an existing HPX application, Octo-Tiger, to use Kokkos instead. We achieve comparable, or better, performance than with previous Vc and CUDA kernels, showing both the viability of our HPX Kokkos integration, as well as future-proofing Octo-Tiger for a wider range of potential machines. Furthermore, we introduce event polling for synchronizing CUDA kernels (or Kokkos kernels on the respective backend) achieving speedups over the previous solution using callbacks.","annote":"","author":[{"family":"Daiß","given":"Gregor"},{"family":"Simberg","given":"Mikael"},{"family":"Reverdell","given":"Auriane"},{"family":"Biddiscombe","given":"John"},{"family":"Pollinger","given":"Theresa"},{"family":"Kaiser","given":"Hartmut"},{"family":"Pflüger","given":"Dirk"}],"citation-label":"dais_beyond_2021","collection-editor":[],"collection-title":"","container-author":[],"container-title":"2021 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW)","documents":[],"edition":"","editor":[],"event-date":{"date-parts":[["2021"]],"literal":"2021"},"event-place":"","id":"cb291e05a1a3bbb91a404b35dfb148a0tpollinger","interhash":"23aeada47e005c4caa88b8ee189c767a","intrahash":"cb291e05a1a3bbb91a404b35dfb148a0","issue":"","issued":{"date-parts":[["2021"]],"literal":"2021"},"keyword":"{HPX} myown Performance {CUDA} Portability hpc Task-based {GPU} Kokkos","misc":{"eventtitle":"2021 {IEEE} International Parallel and Distributed Processing Symposium Workshops ({IPDPSW})","shorttitle":"Beyond Fork-Join","doi":"10.1109/IPDPSW52791.2021.00066"},"note":"","number":"","number-of-pages":"9","page":"377--386","page-first":"377","publisher":"","publisher-place":"","status":"","title":"Beyond Fork-Join: Integration of Performance Portable Kokkos Kernels with HPX","type":"paper-conference","username":"tpollinger","version":"","volume":""},"2107c5fc20a6011daa68f70fa4309d1dmariawirzberger":{"DOI":"","ISBN":"","ISSN":"","URL":"","abstract":"","annote":"","author":[{"family":"Wirzberger","given":"Maria"},{"family":"Borst","given":"Jelmer P"},{"family":"Krems","given":"Josef F"},{"family":"Rey","given":"Günter Daniel"}],"citation-label":"Wirzberger2019MathPsych","collection-editor":[],"collection-title":"","container-author":[],"container-title":"52nd Annual Meeting of the Society for Mathematical Psychology.
