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. ...

Intergenerationelle Weitergabe von Traumatisierungen im Kontext von kollektiver Verfolgung und Zwangsmigration
(2019)
Die kumulative Dissertation beschäftigt sich mit Traumatisierungen durch kollektive Verfolgung und Gewalt. Sie geht der Frage nach, wie diese Traumatisierungen sich auf elterliche Fähigkeiten und auf die Kinder der Traumatisierten auswirken. Ein besonderer Fokus liegt auf den zusätzlichen Herausforderungen von durch Krieg und Verfolgung erzwungener Migration.
Auf eine inhaltliche Einführung zum Thema intergenerationelle Weitergabe von Traumatisierungen werden die beiden Forschungskontexte sowie meine Tätigkeiten ...

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 ...

Semantic congruency and the (reversed) Colavita effect in children and adults
(2016)
When presented with auditory, visual, or bimodal audiovisual stimuli in a discrimination task, adults tend to ignore the auditory component in bimodal stimuli and respond to the visual component only (i.e., Colavita visual dominance effect). The same is true for older children, whereas young children are dominated by the auditory component of bimodal audiovisual stimuli. This suggests a change of sensory dominance during childhood. The aim of the current study was to investigate, in three experimental conditions, ...

Symbolic versus non-symbolic magnitude estimations among children and adults
(2014-07-30)
The ability of children and adults to generate symbolic and non-symbolic magnitude estimations was examined in the light of their familiarity with numbers. Children (6-year-old kindergartners, 7-year-old first graders, and 9-year-old third graders) and adults made symbolic estimations either by saying number words that matched numbers of dots (i.e., perception task) or by generating numbers of dots that matched given number words (i.e., production task). In the non-symbolic estimation task, participants generated the ...

What Do Coaches Actually Do? A Context-Sensitive Approach to Workplace Coaching
(2021)
Vor dem Hintergrund einer noch wenig fortgeschrittenen Forschung zu Wirkfaktoren von Coaching, zielt diese Dissertation darauf ab, die in neueren Forschungsarbeiten skizzierten Forschungslücken hinsichtlich Coach-Verhalten und Kontextfaktoren zu schließen. Um den Blickwinkel auf relevante Kontextfaktoren zu erweitern, liegt der Fokus auf dem Verhalten von Coaches in zwei verschiedenen Arten von Kontexten: dem Beginn von Coaching-Prozessen (d.h. der Eingangsdiagnostik) und Coaching für Gründer*innen.
