General Belief in a Just World Is Positively Associated with Dishonest Behavior
(2017-10-10)
According to the just-world theory, people need to – or rather want to – believe that they live in a just world where they will receive what they earn and consequently earn what they receive. In the present work, we examined the influence of people’s general and personal beliefs in a just world (BJW) on their (dis)honest behavior. Given that general BJW was found to be linked to antisocial tendencies, we expected stronger general BJW to be linked to more dishonesty. Given that personal BJW was found to be correlated ...

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. ...

Krisenbewältigung und Professionalität von Supervisoren
(2019)
Die vorliegende Arbeit entstand aus dem Interesse, die Entstehung eines professionellen Habitus bei langjährig erfahrenen Supervisoren nachzuvollziehen und diesen Prozess mittels empirischer Methoden zu dokumentieren. Bisher liegen m.W. keine Studien vor, die anhand von narrativ-biographischen Interviews mit Supervisoren die Bedeutung der Bewältigung von Krisen für die Bildung eines professionellen supervisorischen Habitus untersuchen, geschweige denn Nachweise für diesen Zusammenhang zu erbringen.

Towards A Better Understanding of Workplace Coaching: On Goal Activities, Exploration Practices, and Coaches’ Life Satisfaction
(2020)
Whereas there is a high and ever-increasing demand for coaching worldwide (International Coach Federation, 2016) and meta-analytical findings suggest that coaching is generally effective (e.g., Jones et al., 2016; Sonesh, Coultas, Lacerenza et al., 2015), little is still known about standards for “good” coaching practice (e.g., Bono et al., 2009; Vandaveer et al., 2016). Across three studies, this dissertation investigates relevant facets of coaching practice. It addresses the questions of how coaches practice workplace ...

Knowledge Is Power for Medical Assistants: Crystallized and Fluid Intelligence As Predictors of Vocational Knowledge
(2018-02-01)
Medical education research has focused almost entirely on the education of future physicians. In comparison, findings on other health-related occupations, such as medical assistants, are scarce. With the current study, we wanted to examine the knowledge-is-power hypothesis in a real life educational setting and add to the sparse literature on medical assistants. Acquisition of vocational knowledge in vocational education and training (VET) was examined for medical assistant students (n = 448). Differences in ...

Sound Matters
(2021-08)
Language sounds, i.e., phonemes, are believed not to bear any meaning themselves, only at the word level, meaning is created. However, numerous studies over the past 100 years have revealed iconic relationships, i.e., a certain fit, between language sounds and word meanings, with regard to several semantic dimensions, such as size, shape, brightness, or distance. This suggests iconicity as a functional mechanism in language. To examine the underlying cognitive processes, a holistic operationalization of iconicity in ...

Shape But Not Color Facilitates Two-Year-Olds’ Search Performance in a Spatial Rotation Task
(2018)
Children younger than 3 years of age often fail to track hidden objects that are rotated together with identical hiding containers, which might be due to relatively complex paradigms. We examined whether 2-year-olds (N = 28) are already able to track spatial rotations (i.e., by 90° and 180°) if the task is facilitated by increasing the visual discriminability of the hiding containers by means of different shapes and different colors. Children performed above chance level in all conditions except for the condition in ...

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 ...

Girls in detail, boys in shape: Gender differences when drawing cubes in depth
(2013)
The current study tested gender differences in the developmental transition from drawing cubes in two‐ versus three dimensions (3D), and investigated the underlying spatial abilities. Six‐ to nine‐year‐old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. ...

Die Dunkle Triade und Täuschung
(2021)
Die vorliegende Dissertationsschrift gliedert sich in zwei Teile: die Synopse und einen empirischen Teil (Anhänge A bis C). In der Synopse werden die empirischen Ergebnisse zusammengefasst und mit bestehenden Forschungsergebnissen kontextualisiert. Der empirische Teil umfasst alle Studien, die im Rahmen der Dissertation durchgeführt und publiziert wurden. Die Ergebnisse der Studien konvergieren dabei auf ein Assoziationsmuster der DT-Persönlichkeitseigenschaften mit Täuschungsvariablen, das von substanziellen ...
