  • Blessed be ye poor: An open and citizen-focused approach to study cultural religiosity

    Principle Investigator: Jana Berkessel (MZES), ORCIDid 

    Abstract: Lower socioeconomic status (SES) can harm psychological well-being, an effect responsible for widespread human suffering. In a previous, large-scale correlative study, we have found that cultural religiosity can buffer this psychological burden of lower SES. In the proposed project I want to apply a citizen science approach to take a more in-depth look at the underlying processes of the buffering effect of cultural religiosity. In a first exploratory study, I will engage participants from various cultural and religious backgrounds to generate hypotheses as to which religious norms could potentially buffer the negative consequences of lower SES. In a second confirmatory study, I will then competitively test these religious norms as process variables.

  • Understanding the underlying mechanisms of cross-linguistic influence: Evidence from priming in German-Italian bilinguals

    Principle Investigator: Dr. Ioli Baroncini, ORCIDid

    Abstract: Cross-linguistic influence (CLI), i.e., the use/acceptance of a linguistic property in one of bilinguals’ languages under the influence of the other, is a widely attested phenomenon. However, it is still not clear why it occurs, what are its limits and whether its strength is influenced by age. The goal of this study is to shed light on these unanswered questions by examining a specific type of CLI: the production of null and overt subjects by German-Italian bilinguals. By conducting two priming experiments across languages with bilinguals of different ages, we will test theoretical predictions concerning which conditions are necessary for CLI to occur, as well as examining the role of age in this process. Results will advance our understanding of bilingualism and will help language education professionals understand how to support second language learners.

  • Can emotions explain how threat rhetoric shapes preferences for freedom versus security

    Principle Investigator: Dr. Sandra Morgenstern (MZES), ORCIDid and Felix Jäger (MZES)

    Abstract: It is increasingly becoming a stylized fact that threat rhetoric influences the formation of political preferences. However, the underlying causal mechanism remains unclear. This is due in no small part to the challenges of conducting a causal mediation design in which the independent and mediator variables must be randomly and independently manipulated. In our theoretical model, we argue that strategic emotional appeals in threat rhetoric elicit different emotions in the recipient, which in turn mediate support for policies related to the liberty-security nexus. To trans­late this into a rigorous research design, we propose a survey experiment with a parallel encouragement design. In addition to a treatment based on recent migration newspaper articles, we experimentally divide the sample into two groups (parallel) and indirectly manipulate the emotion mediator via an emotion memory task (encouragement) in one of them.

  • Negativity Bias in Source Memory: What Are the Effects of Age and Experimental Environment?

    Principle Investigator: Dr. Nikoletta Symeonidou

    Abstract: Previous studies have shown that people remember socially threatening contexts (= sources) better than safe or neutral contexts. In a preceding study, we could extend this memory benefit to negative contexts in general, suggesting a negativity bias in source memory. Based on this, I would like to investigate whether older adults show similar memory benefits for emotional contexts, using more naturalistic materials (faces paired with scenery pictures). The study is planned to be conducted online and in the lab to check whether (and if yes, why) results potentially differ between the lab and the (increasingly popular) online environment.

  • Mannheim Content Analysis of Media Frames Benchmark dataset

    Principal Investigator: Dr. Chung-hong Chan (MZES/School of Humanities),

    Abstract: The project consists of creating a dataset de novo that can be used for benchmarking the performance of content analysis of media frames. This dataset will be released under a permissive license. The dataset will contain both the media content and the ground truth status of the so-called “generic” media frame: attribution of responsibility frame, conflict frame, economic consequences frame, human interest frame, or morality frame. Experiments will be performed to test how close the articles in this de novo dataset resemble actual news.

  • Creation and Validation of an Open-Access Dictionary for Text-Based Personality Assessment

    Principal Investigator: Dr. Tobias Ebert (School of Social Sciences/MZES),
    Co-Investigators: Friedrich Götz (University of British Columbia) and Michael Ohlinger (University of Mannheim)

    Abstract: Digitalization and the big data revolution provide unprecedented amounts of textual data. Previous research has shown that it is possible to predict personality from such textual data. This offers unprecedented possibilities for personality psychologists. First it allows to assess personality fast and in unprecedented magnitudes. Second it gives access to persons or groups which are difficult to access otherwise. However, currently, there are high methodological entry barriers to conduct such research. Specifically, even for the most widely studied personality taxonomy (i.e., Big Five traits) there exists no open-access tool to extract personality from text-data. We here introduce a novel data source (trans­cripts of famous TV-shows) to create exactly such a free, easy to use, open-access tool for text-based personality assessment.

  • A post-pandemic roadmap for the Mannheim Open Science Meetup

    Principal Investigator: Jana Berkessel [since 2022] (MZES),
    Felix Henninger [until 2021] (MZES),
    Co-Investigators: Dr. Ira Maschmann (University of Mannheim), Juliane Tkotz (ZI Mannheim) and Dr. Alexander Wuttke (University of Mannheim)

    Abstract: The Mannheim Open Science Meetup has become a central meeting point for local researchers interested in adopting trans­parent research practices. As the restrictions for in-person meetings are lifted, we are looking forward to returning to physical meetings with an expanded range of topics and speakers, with the goal of attracting more colleagues from more disciplines and covering topics in further details than was possible so far. Besides increasing the reach of the meetup locally we want to strengthen links between the local community and related initiatives by inviting further guests and sending members of our team to other locations, representing the local community and the University of Mannheim in particular.

  • The articulatory in-out effect – an integrative approach

    Principal Investigator: Moritz Ingendahl (School of Social Sciences),
    Co-Investigators: Dr. Ira Maschmann (University of Mannheim) and Prof. Dr. Tobias Vogel (Darmstadt University of Applied Sciences)

    Abstract: The articulatory in-out effect describes the empirically robust preference for linguistic stimuli with an inward (e.g., BODIKA) over stimuli with an outward (e.g., KODIBA) consonant sequence. We outline a research plan to test a theoretical model that integrates different processes to reconcile mixed findings from previous research on the in-out effect.

  • Color-validity associations put to the test: Examining the robustness of red-false and green-true associations in the Implicit Association Test

    Principal investigator: Dr. Lena Nadarevic (School of Social Sciences),
    Co-Investigators: Alina Kias (University of Mannheim)

    Abstract: In this project we aim to investigate color-validity associations with the Implicit Association Test (IAT). Based on a series of four IAT experiments in which we examined color-validity associations across different color contexts and stimulus materials, we want to test the underlying mechanism of the observed IAT effects in a final, to be preregistered experiment. Previous research has shown that IAT effects cannot only stem from conceptual associations of categories, but that other stimulus similarities can also drive IAT effects. For this reason, the goal of the planned experiment is to test if the previously observed findings truly reflect color-validity associations or, alternatively, can be explained by differences in stimulus salience or valence instead of validity.

  • AI, Information Processing and Dissemination

    Principal Investigator:Dr. Florian Pethig (Business School),
    Co-Investigators: Dr. Kevin Bauer (Leibniz Institute for Financial Research SAFE), Prof. Dr. Hartmut Hoehle (University of Mannheim)

    Abstract: Humans increasingly engage with information created or augmented by artificial intelligence (AI). While prior work mainly considers the demand for information, little work has studied how humans process and disseminate AI-generated information once they obtain it. Specifically, our research aims to contribute to this novel research stream by studying (i) how humans process and act upon AI-generated compared to human-generated information, and (ii) how humans disseminate AI-generated information. We will perform a series of preregistered and incentivized online experiments to advance open science and contribute to the understanding of human perceptions of AI.

  • Meinungs­freiheit auf dem Campus – Eine pre-registered, adversarial collaboration

    Principal investigator: Dr. Alexander Wuttke (MZES),
    Co-Investigators: Richard Traunmüller (University of Mannheim) and Matthias Revers (University Leeds)

    Abstract: Wissenschaft­liche Kontroversen werden in der Regel in Form von Kritik und Gegenkritik ausgetragen. Dieser Form des wissenschaft­lichen Dialogs dokumentiert Dissens, aber vermag nicht ihn aufzulösen und leistet daher in der Regel kinen Beitrag um den allgemein akzeptierten Wissensbestand einer Disziplin zu mehren.
    Am Beispiel einer Studie zur Meinungs­freiheit an deutschen Universitäten, die in Forschung und Tagespresse für großes Aufsehen gesorgt hatten, demonstrieren wir wie sich die Unter­schiedlichkeit der Perspektiven durch Open Science Methoden konstruktiv nutzen lassen. In einer pre-registered adversarial collaboration werden KritikerInnen und Originalforscher zusammenkommen und sich gemeinsam auf ein Studien­design zu einigen.
