These two variables are often treated as dependent variables influenced by a particular robot design or behavior. However, psychological literature suggests that people have individual tendencies to anthropomorphize, influencing these two variables. We ran an experiment in which 70 participants were confronted with two robots, a humanoid and a non-humanoid robot. Before exposing them to the robots, they were screened for their individual tendency to anthropomorphize. After exposure, they rated the robots in terms of anthropomorphism and trust. With this experiment, we show that the individual tendency to anthropomorphize has a clear impact on measuring anthropomorphism and trust with frequently used questionnaires. Given our results, we emphasize that future studies should screen participants for their tendency to anthropomorphize to avoid unwanted biases.}, language = {en} } @inproceedings{OPUS4-4923, title = {Wirtschaft, Psychologie und Nachhaltigkeit}, series = {29.

Die 29. Fachtagung der Gesellschaft f{\"u}r angewandte Wirtschaftspsychologie widmet sich diesem Zusammenspiel und r{\"u}ckt die Frage in den Mittelpunkt, wie {\"o}kologische, {\"o}konomische und soziale Transformation so gestaltet werden kann, dass sie von Menschen verstanden, mitgetragen und aktiv mitgestaltet wird. Die Tagung an der Westf{\"a}lischen Hochschule in Gelsenkirchen bringt Studierende, Wissenschaftler*innen und F{\"u}hrungskr{\"a}fte aus der Praxis an einem Ort zusammen, an dem die Erfahrung von Strukturwandel und Fragen der Zukunftsf{\"a}higkeit seit Jahrzehnten zum Alltag geh{\"o}ren. Vor diesem Hintergrund bietet die GWPs ein Forum, in dem wissenschaftlich fundierte und empirisch belastbare Erkenntnisse mit praxisnahen Gestaltungsans{\"a}tzen verbunden werden. Sie steht f{\"u}r angewandte Forschung mit Anspruch an Rigor und Relevanz. Die in diesem Band versammelten Beitr{\"a}ge machen deutlich, wie vielf{\"a}ltig und zugleich unmittelbar relevant wirtschaftspsychologische Perspektiven f{\"u}r die Nachhaltigkeitstransformation sind. Sie widmen sich Fragen der Arbeitswelt, Gesundheit und Motivation ebenso wie demokratischen Einstellungen und gesellschaftlicher Teilhabe. Sie beleuchten Akzeptanzprozesse in Mobilit{\"a}t, Technologie und K{\"u}nstlicher Intelligenz, diskutieren Konsumentenverhalten, soziale Verantwortung, Bildungs- und Hochschulentwicklung sowie organisationale Ver{\"a}nderungen. Damit zeigen sie eindr{\"u}cklich, dass nachhaltige Transformation nicht allein eine technische, politische oder wirtschaftliche Aufgabe ist, sondern in besonderem Maße eine psychologische. Wir verstehen diese Tagung daher als Einladung zum Dialog: zwischen Disziplinen, zwischen Forschung und Praxis sowie zwischen den unterschiedlichen Handlungsfeldern, in denen Nachhaltigkeit konkret wird und den Akteur*innen, die sie gestalten. Unser Ziel ist es, Orientierungswissen bereitzustellen, konstruktive Perspektiven zu er{\"o}ffnen und Impulse zu geben, wie wirtschaftspsychologische Erkenntnisse dazu beitragen k{\"o}nnen, nachhaltige Entwicklungen wirksam, akzeptiert und menschlich zu gestalten. Wir danken allen Autor*innen f{\"u}r ihre engagierten Beitr{\"a}ge sowie allen Beteiligten, die durch Organisation, Diskussion und Mitwirkung zum Gelingen dieser Tagung beitragen.

Regardless of this variety, educators wonder whether they can make use of these tools for their goals and if so, which tool to choose and in which context a specific tool performs best. To do so, the collection and analysis of learning data - referred to as Learning Analytics (LA) - is required. Along with digital learning environments the possibilities of applying LA are growing. Often, LA focuses on data that can easily be quantified: drop-out quota, time or grade performance. To facilitate learning in a more procedural sense, a deeper understanding of learners' behavior in specific contexts with specific exercise designs is desired. This study therefore focuses on usage patterns. Learners' movements through three different designs of mathematical exercises - (i) plain exercises, (ii) PA supported and (iii) fantasy game design - are analyzed with Markov chains. The results of an experiment with 503 students inform about which design facilitates what kind of learning. While the PA design lets learners enter more partial solutions, the fantasy game design facilitates exercise repetition.}, language = {en} } @inproceedings{ExternbrinkBrounsThiem2025, author = {Externbrink, Kai and Brouns, Tim and Thiem, Verena Katharina}, title = {Leaders' Psychological Costs and Benefits of Servant Leadership: A Conservation of Resources View}, series = {22nd European Congress of Work and Organisational Psychology (EAWOP 2025): Transforming Working Environments: Challenges \& Opportunities.

This gap is crucial, as servant leadership might place significant demands on leaders' psychological resources, without sufficient social, psychological, or organizational rewards. Drawing on the Conservation of Resources Theory (COR), we investigate how and when servant leadership affects leaders' mental health, viewing its role not only as resource-depleting but also as resource-generating for leaders, depending on the organizational context. Two cross-sectional studies were conducted using leader self-assessments (N = 101; N = 170). Study 1 focused on the relationship between servant leadership, experienced meaningfulness, emotional exhaustion, and flourishing, emphasizing the resource-generating potential of servant leadership. Study 2, examined the moderating effect of the distributive justice climate (DJC) on the link between servant leadership and emotional exhaustion, exploring the possibility of resource depletion under conditions of low organizational fairness. Results. In Study 1, servant leadership was found to mitigate emotional exhaustion by enhancing experienced meaningfulness at work. Moreover, it fostered leaders' flourishing through the same mechanism, suggesting that servant leadership can be a source of leaders' well-being. Study 2 demonstrated that DJC moderates the servant leadership-emotional exhaustion relationship. Specifically, when DJC is low, servant leaders are more susceptible to emotional exhaustion, indicating that unfair organizational climates can exacerbate the resource-depleting aspects of servant leadership. Servant leadership has the potential to both reduce and exacerbate emotional exhaustion in leaders. While it generates psychological resources like experienced meaningfulness, which enhances well-being, its effectiveness is influenced by the organizational context. In unjust environments, servant leadership's emotional demands may lead to resource depletion. These findings are in line with COR and highlight the complex impact of servant leadership on the well-being of leaders.

This study analyzes phishing simulations conducted over three years at 36 organizations with over 68 000 delivered emails. We compare different dimensions of the organizations where these simulations were conducted, such as the economic sector and departments. Furthermore, we evaluate various dimensions of phishing simulation campaigns, such as detection difficulty and the scenario under which the simulation occurs.

This study fills this gap by extensively analyzing these features within the European HbbTV ecosystem, and in particular within German-language TV channels. We monitored more than 350 TV channels for over 400 hours, evaluating 1) prevalent HbbTV tracking methods, 2) consent notice prevalence and user interactions, and 3) privacy policy disclosures.

We demonstrate Shaalke's capability to accurately determine STC parameters and both static and dynamic temperature coefficients, showing excellent agreement with manufacturer specifications and independent laboratory measurements. A key finding is Shaalke's precise mapping of the irradiance dependence of module efficiency, filling a significant gap left by typical datasheet values which often only provide data at 1000 and 200 W/m². Furthermore, the tool enables reliable power degradation analysis, identifying modules that exceed manufacturer-tolerated limits.
