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 ...

Zusammenhang der Nutzungshäufigkeit mit der Wirksamkeit eines angeleiteten Online-Selbsthilfeprogramms bei depressiven Patienten
(2022)
Zusammenhang der Nutzungshäufigkeit mit der Wirksamkeit eines angeleiteten Online-Selbsthilfeprogramms bei depressiven Patienten:
Die Deprexis-Studie, die Basis meiner Arbeit ist, hat gezeigt, dass eine webbasierte Selbsthilfe als Ergänzung zur multimodalen stationären psychotherapeutischen Behandlung den Verlauf der depressiven Symptome verringern kann und so die Wirkung der stationären Psychotherapie durch die Integration einer zusätzlichen Online-Intervention verbessert. Eine Stichprobe von 115 Patient*Innen, ...

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 ...

Suizidprävention Deutschland
(Deutsche Akademie für Suizidprävention e.V. (DASP), 2021-08)
In jedem Jahr sterben in Deutschland mehr als 9.000 Menschen durch Suizid. Durch jeden Suizid sind mittelbar mehr als 100.000 weitere Menschen betroffen. Vor diesem Hintergrund hat das Bundesministerium für Gesundheit Mittel für ein Projekt zur Verfügung gestellt, um eine Grundlage für die weitere Entwicklung der Suizidprävention zu gewinnen. Das Projektziel war die Erstellung eines wissenschaftlich fundierten umfassenden Berichts zur Suizidproblematik, der Suizidprävention und deren Perspektiven in Deutschland. Der ...

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 ...

Implementing Distributed Practice in Statistics Courses: Benefits for Retention and Transfer
(2020-11-18)
The present study investigated the effect of distributed versus crammed practice before a course deadline on the retention and transfer of knowledge, and whether learner characteristics moderate the effect. In Experiment 1, only 41% (N = 38) of the initially enrolled students worked the voluntary but recommended practice tasks. Moreover, markedly fewer students did so in the distributed condition (12%) than the crammed practice condition (29%). In Experiment 2, working the practice tasks was mandatory and more students ...

Caught in the Act: Predicting Cheating in Unproctored Knowledge Assessment
(2020-05-20)
Cheating is a serious threat in unproctored ability assessment, irrespective of countermeasures taken, anticipated consequences (high vs. low stakes), and test modality (paper-pencil vs. computer-based). In the present study, we examined the power of (a) self-report-based indicators (i.e., Honesty-Humility and Overclaiming scales), (b) test data (i.e., performance with extremely difficult items), and (c) para data (i.e., reaction times, switching between browser tabs) to predict participants’ cheating behavior. To ...

On the Trail of Creativity: Dimensionality of Divergent Thinking and its Relation with Cognitive Abilities, Personality, and Insight
(2020-12-02)
Divergent thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report relationships between DT and its aspects with relevant covariates, such as cognitive abilities, personality traits (e.g. openness), and insight. In two multivariate studies (N = 152 and N = 298), we evaluate competing measurement models for a variety of DT tests and examine the relationship between DT and established cognitive abilities, personality ...

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 ...

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 ...
