Publication Not just for your health alone: Regular exercisers' decision-making in unrelated domains(American Psychological Association, 2022-01-10) Zimmermann, Laura; Chakravarti, Amitav; https://ror.org/02jjdwm75Do regularly physically active individuals differ in their decision making from people who are not regularly physically active? Across five studies, we document a novel benefit of being regularly physically active for decisions that require the appropriate weighing of goal-relevant versus goal-irrelevant information. Usually, when faced with a mix of relevant and irrelevant attribute information, decision makers find it difficult to ignore the irrelevant information, and as such, “dilute” their judgments (i.e., judgments become less extreme). Such a dilution effect has been amply documented in past research. In contrast, we find that people who engage in regular leisure physical activity are less susceptible to dilution effects. Beyond the dilution effect, we also find similar benefits of being regularly physically active for decisions involving desirability-feasibility trade-offs. The results hold across multiple replicates, diverse samples, and different measures of regular physical activity. We also rule out several potential alternative accounts (e.g., demographics, personality traits). The results cannot be explained by physical effort alone as these benefits are observed only for regular leisure physical activity and not for occupational physical activity.Publication “Your Screen-Time App Is Keeping Track”: Consumers Are Happy to Monitor but Unlikely to Reduce Smartphone Usage(The University of Chicago Press, 2021-07) Zimmermann, Laura; https://ror.org/02jjdwm75Can screen-time applications help to control smartphone usage? Maladaptive consumption in the form of smartphone overuse is a concern for many consumers. As a solution, screen-time applications were launched by the largest technology companies. This research predicts that, while improving screen-time knowledge, tracking apps are less likely to empower users to reduce actual usage. Study 1, a longitudinal field study (N=242), shows that screen-time tracking improves digital self-awareness but that it is less likely to lead to a reduction of mobile usage. The results also reveal a small negative association between smartphone usage and performance at university. Study 2, an online experiment (N=139), uncovers that consumers prefer informational tracking over more restrictive alternatives (blocking, digital nudges), despite evaluating it as less effective for reducing screen time—especially those highest in smartphone dependence. These findings suggest that many people want to monitor their smartphone usage but not necessarily control it.Publication Digital Strategies for Screen Time Reduction: A Randomized Field Experiment(Mary Ann Liebert, 2023-01-17) Zimmermann, Laura; Sobolev, Michael; https://ror.org/02jjdwm75Many consumers nowadays wish to reduce their smartphone usage in the hope of improving productivity and well-being. We conducted a pre-registered field experiment (N = 112) over a period of several weeks to test the effectiveness of two widely available digital strategies for screen time reduction. The effectiveness of a design friction intervention (i.e., activating grayscale mode) was compared with a goal-setting intervention (i.e., self-commitment to time limits) and a control condition (i.e., self-monitoring). The design friction intervention led to an immediate, significant reduction of objectively measured screen time compared with the control condition. Conversely, the goal-setting intervention led to a smaller and more gradual screen time reduction. In contrast to the popular belief that reducing screen time has broad benefits, we found no immediate causal effect of reducing usage on subjective well-being and academic performance.Publication Adoption of New Technology Vaccines(SAGE Publications, 2023-11-29) Zimmermann, Laura; Somasundaram, Jeeva; Saha, Barsha; Agencia Estatal de Investigación; European Regional Development Fund; https://ror.org/02jjdwm75Extensive research has examined the diffusion of innovations for products that can be trialed, and where the most adverse outcome, if a product fails, is a financial loss. However, less research has explored consumer responses to innovations in highly uncertain contexts characterized by health losses, lack of trialability, and the opportunity to free ride on other's adoption. This research focuses on vaccine decision making as a unique case within such contexts and extends the findings to other domains. Four studies (Ntotal = 1,796; five supplementary studies, Ntotal = 643) test the propositions of a formal model that incorporates uncertainty and others' choices into the adoption decision. The results show that consumers are surprisingly averse to products that are described as employing a new technology (e.g., mRNA technology) and require an “efficacy premium” to compensate for higher perceived uncertainty. However, considerable heterogeneity exists due to individual differences in technology readiness, trust in government, and risk attitudes. Notably, despite the prominent threat of free riding, a social proof nudge (communicating increasing population adoption) effectively reduces aversion to new technology. In this context, social proof information does not merely drive conformity or social learning, but instead increases adoption of new technology by alleviating perceived uncertainty.Publication Maladaptive Smartphone Usage(Palgrave Macmillan Cham, 2024-07-30) Zimmermann, Laura; Somasundaram, Jeeva; https://ror.org/02jjdwm75This chapter examines the phenomenon of maladaptive smartphone consumption, considering its detrimental effects on individuals and exploring potential strategies to overcome this behavior. Despite the many beneficial aspects of smartphones, growing concern has been raised about the potential maladaptive nature of excessive smartphone usage. This chapter provides an overview of the literature on this topic. Specifically, we explore the habitual nature of smartphone usage and under what conditions it should be considered maladaptive. We further provide an overview of existing research on adverse consequences of smartphone usage for subjective wellbeing, cognition, academic performance, and employment-related consequences of smartphone overuse as well as social outcomes (e.g., phubbing). To overcome maladaptive smartphone usage, we summarize interventions to reduce smartphone usage based on different mechanisms (e.g., self-control approaches, digital nudges and design frictions, incentives) and highlight measurement issues when researching this topic. We conclude by providing recommendations for policy-makers, researchers, and businesses dealing with maladaptive smartphone consumption. Overall, this book chapter provides a comprehensive examination of maladaptive smartphone consumption, its consequences, and potential solutions. By addressing the multifaceted aspects of this behavior, it offers insights for researchers, firms, and policy-makers alike.Publication Recent developments in Behavioural Public Policy: IBPPC 2022(Cambridge University Press, 2024) Banerjee, Sanchayan; Hortal, Alejandro; Dold, Malte; Ivchenko, Andriy; Lades, Leonhard; Savani, Manu ; McDonald, Rebecca; Zimmermann, Laura; https://ror.org/02jjdwm75[No abstract available]
