- PublikationAufrechterhaltung eines gesunden Lebensstils(Springer, 03/2023) Schäfer, Adrienne; Schaffner, Dorothea; von dem Berge, Karina; Studer, Nora; van der Heiden, Nico; Zimmermann, AnjaMit einer nachhaltigen Lebensstilveränderung, die auf ausreichend Bewegung und ausgewogener Ernährung basiert, können viele chronische Krankheiten (Übergewicht, Bluthochdruck, Diabetes, metabolisches Syndrom) gelindert, geheilt oder deren Ausbruch verhindert werden. Betroffenen fällt es schwer, den Lebensstil dauerhaft umzustellen. Häufig sind Interventionsprogramme nicht auf eine nachhaltige Verhaltensänderung ausgerichtet und berücksichtigen die motivationalen Faktoren der Individuen zu wenig. Betroffene fallen daher nach einiger Zeit in alte Muster zurück. Das angewandte Forschungsprojekt „Nachhaltiger Lifestyle Change“, das in diesem Buch behandelt wird, beschäftigt sich mit der Frage, wie das „Dranbleiben“ an einem gesunden Lebensstil aus Sicht der Motivationspsychologie und der Dienstleistungsorientierung unterstützt werden kann.02 - Monographie

- PublikationSelf-explaining roads: Effects of road design on perception and speed choice(08/2022) Schaffner, Dorothea; van Eggermond, Michael; Studer, NoraSince speed is a crucial factor contributing to car accidents, one of the greatest potentials for improving road safety lies in reducing driving speed (Aarts and van Schagen, 2006). Conventional measures such as speed limits and law enforcement have their merit but also limitations. A complementary measure to achieve speed reduction is based on the concept of self-explaining roads (SER; Theeuwes & Godthelp, 1995). The concept postulates that road design impacts speed choice based on psychological factors of perception. Previous research has demonstrated the impact of road design on speed choice for a limited number of road design features (e.g. curves, road width). Furthermore, existing research only offers limited insights into the psychological mechanisms driving these effects. Therefore, this experimental study, first, aims to the impact of several novel road features on speed choice. Second, it analyses the underlying psychological mechanisms, explaining the effects of road design on speed choice.06 - Präsentation
- PublikationEnergy Efficient Homes: The Role of Social Norms and Influencers in Homeowners’ Decision Making(10/2021) Schaffner, Dorothea; Kuster, DeniseThe building sector plays a significant role in climate change due to carbon emissions and energy over-consumption related to the use of non-renewable energy sources and insufficient insulation. Private homeowners could contribute to achieving climate change targets in the building sector by refurbishing their homes to meet stricter energy efficiency standards. However, the realization of respective investments in energy-efficient heating systems or retrofitting remains insufficient. Against this background, drivers and barriers of homeowners’ decision making have been investigated by a considerable number of empirical studies. These previous studies have focused on economic and rational determinants of investment decisions, finding only little support for the influence of determinants such as subsidies or energy savings. Consequently, the present study proposes a novel approach to better understand the relevant factors of decision-making. Featuring a socio-psychological perspective this study explores homeowners’ decision-making within a social context. Thereby the study includes the viewpoint of homeowners as well as relevant influencers such as installers. A qualitative study with ten semi-structured interviews was conducted. The sample consisted of six homeowners and four installers. Findings reveal that social norms (e.g., opinions of friends and neighbors) as well as recommendations of influencers (such as installers) play a crucial role to persuade homeowner to invest in energy-efficient homes. Based on these findings, the study proposes several measures that address social norms (best practice examples, case studies) and suggests including installers as important target groups in campaigns promoting energy-efficient homes06 - Präsentation
- PublikationChancen einer digitalisierten Reisekette: Kundenerwartungen an den öffentlichen Verkehr(DVV Media Group, 10/2021) Schaffner, Dorothea; Hauser, Mirjam; Studer, Nora; Brüngger, Jonas; Langenauer, Fredy [in: Eisenbahntechnische Rundschau]Die Studie zeigt: Digitale Informationsangebote für die Reiseplanung und Durchführung haben die höchste Kundenpräferenz. Bei der Nutzung digitaler Services stehen Datenschutzbedenken im Hintergrund – eine Lenkung hinsichtlich des «besten» Reiseweges ist teilweise sogar erwünscht. Das Interesse an autonomen On-Demand Shuttles ist noch verhalten, hat aber für bestimmte Zielgruppen wie Autofahrer Potential – hier wird es auf die Ausgestaltung und Kommunikation ankommen.01B - Beitrag in Magazin oder Zeitung

- PublikationStudying bicyclists’ perceived level of safety using a bicycle simulator combined with immersive virtual reality(Elsevier, 2021) Nazemi, Mohsen; van Eggermond, Michael; Erath, Alexander; Schaffner, Dorothea; Joos, Michael; Axhausen, Kay W. [in: Accident Analysis & Prevention]There is a need for methods that provide a better understanding of bicyclists’ perceived safety and preferences on currently unavailable and/or unknown bicycle facilities. Different survey methods have been used to study bicyclists’ behavior, experiences, and preferences; ranging from verbally described facilities to surveys including images and videos. Virtual Reality (VR) experiments blur the boundaries between stated preference (SP) surveys and revealed preference (RP) surveys and provide a realistic sense of design. This research introduces a novel research method in bicycling research and discusses the results of an experiment using a bicycle simulator combined with immersive VR. In total, 150 participants participated in this experiment and were asked about demographics and perceptions and preferences after bicycling in five different environments with an instrumented bicycle in VR. A 5 2 mixed design was used with bicycling environment as within-subject factor and pedestrian / traffic volume as between-subject factor. ANOVA tests revealed how each environment and ambient pedestrian / traffic volume affected perceived level of safety (PLOS) and willingness to bicycle (WTB). Pairwise comparison showed that participants felt safer bicycling on the segregated bicycle path compared to bicycling on the painted bicycle path on the road and roadside. There was no meaningful difference between WTB for less than 10 min and WTB for more than 10 min between bicycling on a painted bicycle path on the sidewalk and painted bicycle path on the road. PLOS and WTB ratings of men and women were not significantly different from each other. The older segment of the sample was more worried about roadside bicycling and bicycle commuters were more confident to ride on the roadside. Despite having several limitations, immersive 360-degree VR was found a powerful presentation tool to evaluate future street designs which can inform transport and urban planning.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationWie bringt man respektvoll produzierte tierische Produkte an die Konsumentinnen und Konsumenten?(Schweizer Tierschutz STS, 21.10.2020) Bürgin, Steven; Schaffner, Dorothea; Sciarra, Cesare [in: 21. Nutztiertagung]Die Vermarktung von respektvoll produzierten tierischen Produkten steht vor der Herausforderung, dass klassische Informationskampagnen wenig erfolgsversprechend sind. Dies weil sich die positiven Einstellungen zum Tierwohls in der Bevölkerung nicht im entsprechenden Konsumverhalten widerspiegeln. Diese Dissoziation wird meat paradox genannt. Die Wirtschaftspsychologie bietet verschiedene Erklärungsansätze für dieses Phänomen und gleichzeitig die Grundlage für psychologisch fundierte Vermarktungsstrategien. Am meisten Erfolg versprechen Massnahmen am Point-of-Sale, welche den gesellschaftlichen Veränderungsprozess dahin gehend unterstützen, dass der Kauf von respektvoll produzierten tierischen Produkten die Norm wird.04B - Beitrag Konferenzschrift
