Taking a Closer Look at the Desirability of Desirable Difficulties - Additionally Focusing on Required Prerequisites, Negative Side-Effects, and Negative Consequences
(2022)
As the title of my dissertation already indicates, the main purpose of the following work was to take a closer, more thorough, and encompassing look at the desirability of desirable difficulties. The term desirable difficulties thereby subsumes varying types of difficult, demanding, and challenging learning strategies—like the application of (learning/practice) tests and generation tasks: Working on and successfully solving those difficult tasks requires more (cognitive) effort compared to working on easier learning ...

A Multi-Perspective Investigation of the Innovation Process: Dynamics, Regulation, and Integration of Concepts
(2021)
This dissertation provides insight into how individuals and teams address the complex and dynamic nature of innovation processes. Focusing on affect and self-regulation, the dissertation investigates how and why regulation efforts of individuals and teams may be beneficial for both innovative activities (i.e., idea generation and implementation) and innovative strategies (i.e., exploration and exploitation). Further, it addresses the issue of conceptual variety in innovation research and examines to what extent ...

Dynamics of Norms in Decision-Making
(2024-01)
So far, there is a lack of understanding how norms change. The aim of the present dissertation was twofold: (1) addressing differences between change processes of different types of norms and (2) focusing more particularly on how norms are internalized. To study norm dynamics, a multi-method approach was chosen, combining theory, social simulation, and experimental research. In the theoretical contribution, a psychologically grounded conceptual model of norm change and decision-making was presented. Based on a refined ...

Risk Communication during the COVID-19 Pandemic
(2024)
In this PhD project it was aimed to learn about the potential and the challenges of risk communication in systemic risks by conducting applied research during the COVID-19 pandemic. Risk communication plays a crucial role in mitigating these risks by addressing risk beliefs in the population and thereby stimulating behavior change. In the synapsis of this project, however, the prevalence of heterogenous prior risk beliefs in different groups of the population were identified as a major challenge for risk communication ...

Operationalized Psychodynamic Diagnosis - Using Network Analysis to Explore the Associations between Psychodynamic Constructs
(2024)
The Operationalized Psychodynamic Diagnosis (OPD) system has established itself in the psychodynamic field as a supplement to descriptive classification systems for mental disorders. The OPD includes key psychodynamic constructs, namely “interpersonal relations”, “psychodynamic conflicts” and “personality structure”. The examination of the interplay among psychodynamic constructs and their associations with psychopathology holds significant relevance for both clinical and scientific practice, as it advances our ...

Factors Influencing the Effectivity and Usage of Desirable Difficulties in Learning
(2019-02)
What circumstantial factors or personality factors influence the effectivity of desirable difficulties, and correspondingly, the attitudes to and the usage of desirable difficulties? The dissertation covers externally regulated (laboratory and classroom) and self-regulated learning and starts with a brief introduction of the concept of desirable difficulties and a literature review of selected papers on disfluency, interleaving and spacing, as well as testing and generation. The literature review focuses on effectivity ...

Investigating distributed practice as a strategy for school students learning mathematics
(2018-09)
Spacing or distributed practice is a prominent learning strategy that is related to the so-called desirable difficulties. With distributed practice, a given learning duration is interrupted by at least one break of variable length. In contrast, with massed practice the same total time is spent learning, but without interruption. There is a rich body of empirical evidence proving the positive effect of distributed practice on the retention of verbal material. Beyond rote memory, however, the empirical grounds regarding ...

An Investigation of the Lie-Telling Personality Type Within Different Social Contexts
(2023)
The present work aimed to further develop and refine the nomological net of personality traits predicting deception within the specific context of romantic relationships, as well as within the academic context. The main findings are that the already established correlation between Honesty-Humility and general deceptive behavior also reliable emerged for relationship-based dishonesty and academic cheating; however, against general deception research, when examining the specific context of romantic relationships, the ...

Leading for innovation: an empirical analysis of ambidextrous leadership
(2019-10)
This dissertation investigates leadership in innovation processes. Based on ambidexterity theory, the focus is on the contradictory aspects of creativity and implementation within the innovation process and how leaders can support employees in addressing them. More specifically, this dissertation takes a within-process perspective looking at the influences of leader behaviors depending on different situations within the innovation process. The ambidextrous leadership model provides concrete leader behaviors defined ...
