Let’s twist again! Embodiment effects in spatial judgments on human figures rotated along a vertical axis
(2017)
We investigated whether individuals used mental rotation and embodiment for arm laterality judgments of human figures that were stepwise rotated from back view to front view along a vertical axis. In Experiment 1, figures’ heads were always shown in profile, while only the bodies were rotated. Judgments were faster and more correct when figures were presented in back view compared to front view, but the relation between reaction times (RTs) and rotation angles was not strictly linear. In addition, judgments on figures ...

Access to the learning material enhances learning by means of generating questions: Comparing open- and closed-book conditions
(2020)
Generating questions referring to the learning material is a powerful learning strategy. The present study investigated potential mechanisms behind this effect. Students (N=231) read a text and then generated questions referring to the text in three conditions: (1) open-book (i.e., text accessible), (2) closed-book (i.e., text inaccessible), and (3) cued closed-book (i.e., text inaccessible but keywords provided). After one week, students’ knowledge gain was larger in the open-book and cued closed-book conditions ...

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds
(2015)
Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence ...

Multifinalität von Verlust- und Trennungserfahrungen in der frühen Adoleszenz
(2022)
Zahlreiche Erkenntnisse aus den bisherigen Untersuchungen zu den langfristigen Auswirkungen einer Scheidung auf die Kinder konvergieren in der Einsicht, dass eine elterliche Trennung mit negativen psychosozialen Folgen einhergehen kann, dies jedoch nicht zwangsläufig muss. Ein einheitliches Muster von Scheidungsfolgen konnte bisher nicht gefunden werden. So zeigten bisherige Studien, dass die individuellen Trennungsverläufe und die damit einhergehenden Stressoren aber auch Ressourcen der Kinder und Familien die ...

Promises and Pitfalls of Machine Learning Modeling in Psychological Research
(2024)
Algorithmen des maschinellen Lernens werden in der Psychologie und ihren Teildisziplinen immer beliebter. Sie werden häufig dafür angepriesen, dass sie mit der Multikollinearität von Prädiktorvariablen und komplexen Beziehungen zwischen Prädiktoren und Kriterien effizient umgehen können. Trotz ihrer Vorteile werden auch immer mehr kritische Stimmen laut, die auf die derzeitigen Grenzen von Vorhersagen durch maschinelles Lernen hinweisen und die Frage aufwerfen, ob die Algorithmen den Erwartungen gerecht werden. ...

Begriff und Psychodynamik des Scheiterns aus psychoanalytischer Sicht am Beispiel des „König Lear Opern Projekts“ von Giuseppe Verdi
(2024)
Die vorliegende Untersuchung fokussiert sich auf die Frage, weshalb sich Giuseppe Verdi als überaus erfolgreicher Komponist von 26 Opern 50 Jahre damit beschäftigte, den „König Lear“ von William Shakespeare zu vertonen, ohne das Projekt jemals auf die Bühne zu bringen. Verdis wiederholtes Aufgreifen und Wiederfallenlassen des Projekts verweisen auf ein hohes Maß an Ambivalenz, sodass sich darüber eine psychoanalytische Fragestellung legitimiert. Die psychoanalytische Untersuchung zielt auf den Zusammenhang zwischen ...

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 ...

On the Path to Professionalization in Coaching: From Coaches' Attitudes for Participating in Coaching Research to Improving Coachees' Reflective Capacity
(2024)
This dissertation aims to advance the professionalization of coaching by advancing coaching research. It does this by meeting the demand for methodological grounding and examining coaches' motives for participating in coaching research, thereby contributing to the generation of larger and more-realistic samples (Study 1), by conducting theory-driven research based on psychotherapy research, and by using an observer-based method to evaluate behavioral data (Study 2). At the same time, it contributes to improving the ...
