Different forms of life satisfaction and their relation to affectivity
(2016-05-03)
Aims: The present study is aimed at studying the research question whether high satisfaction levels achieved through either (1) the fact that one's quality of life is truly satisfactory (i.e., stabilized life satisfaction) or through (2) adapting a more favorable perception of one's quality of life by lowering standards (i.e., resigned life satisfaction) are associated with different levels of positive affect (PA) and negative affect (NA) when compared to each other but also when compared to dissatisfied individuals.

On Measuring Some of the People Some of the Time with Some of the Items: The Search for Stability and Variation in Item Sets
(2019-02)
Psychological assessment is shaped by the items used and the persons assessed. Both items and persons typically represent a random or representative sample of a much larger item and person pool. However, most of the focus on psychological measurement rests on the person sampling side. Item sampling from larger item pools is still a black box. In this dissertation, I present the advantages of new state-of-the-art item and person sampling procedures in the context of personality development research (manuscript 1). ...

Increasing scepticism toward potential liars: effects of existential threat on veracity judgments and the moderating role of honesty norm activation
(Frontiers Research Foundation, 2015)
With the present research, we investigated effects of existential threat on veracity judgments. According to several meta-analyses, people judge potentially deceptive messages of other people as true rather than as false (so-called truth bias). This judgmental bias has been shown to depend on how people weigh the error of judging a true message as a lie (error 1) and the error of judging a lie as a true message (error 2). The weight of these errors has been further shown to be affected by situational variables. Given ...

The Effects of Visual Discriminability and Rotation Angle on 30-Month-Olds’ Search Performance in Spatial Rotation Tasks
(Frontiers Research Foundation, 2016-10-20)
Tracking objects that are hidden and then moved is a crucial ability related to object permanence, which develops across several stages in early childhood. In spatial rotation tasks, children observe a target object that is hidden in one of two or more containers before the containers are rotated around a fixed axis. Usually, 30-month-olds fail to find the hidden object after it was rotated by 180°. We examined whether visual discriminability of the containers improves 30-month-olds’ success in this task and whether ...

Comparing apples and pears in studies on magnitude estimations
(2013-06-18)
The present article is concerned with studies on magnitude estimations that strived to uncover the underlying mental representation(s) of magnitudes. We point out a number of methodological differences and shortcomings that make it difficult drawing general conclusions. To solve this problem, we propose a taxonomy by which those studies could be classified, taking into account central methodological aspects of magnitude estimation tasks. Finally, we suggest perspectives for future research on magnitude estimations, ...

Elterliche Geschlechtsstereotype und deren Einfluss auf das mathematische Selbstkonzept von Grundschulkindern
(2011-10-21)
Ausgangspunkt dieser Dissertation ist die Überlegung, warum Mädchen und Frauen in mathematisch-naturwissenschaftlichen Fächern und Berufen unterrepräsentiert sind. Irrtümlicherweise werden als Erklärung hierfür häufig Geschlechterdifferenzen in der Mathematikleistung herangezogen. Diese bieten jedoch aufgrund nicht einheitlicher Forschungsbefunde keinen zufriedenstellenden Erklärungsansatz. Naheliegender ist es, das mangelnde Selbstvertrauen von Mädchen in Mathematik (als mathematisches Selbstkonzept bezeichnet) als ...

Working after hours, sharing availability expectations, and interrupting yourself: Extending perspectives on ICT-related concepts in research
(2019)
This dissertation investigates Information and Communication Technologies (ICTs) and their role for recovery, well-being, and performance at work. The three empirical studies compiled in this dissertation investigate the influence of ICT work-related use at work and at home, as well as supervisors’ expectations regarding extended availability. The three main goals of the dissertation were to explore alternative ways of understanding ICT-related concepts, to identify additional factors that change their impact and the ...

The Positive Facet of Self-compassion Predicts Self-reported Use of and Attitudes toward Desirable Difficulties in Learning
(2017-08-09)
Previous research found that introducing difficulties and challenges during learning has desirable outcomes. With the present work, we investigated the question how the use of and the attitudes toward such learning strategies (so-called desirable difficulties) are related to self-compassion, a concept that describes the tendency to be understanding and kind to oneself when confronted with negative experiences. Evidence suggests self-compassion to be linked to less fear of failing, and further to higher control beliefs ...

Children’s use of number line estimation strategies
(2015-03-22)
This study tested whether second graders use benchmark-based strategies when solving a number line estimation (NLE) task. Participants were assigned to one of three conditions based on the availability of benchmarks provided on the number line. In the bounded condition, number lines were only bounded at both sides by 0 and 200, while the midpoint condition included an additional benchmark at the midpoint and children in the quartile condition were provided with a benchmark at every quartile. First, the inclusion of ...

Leading and Following Day by Day
(2018)
This dissertation deals with daily leader-follower interactions, alignment of words and actions, well-being and effectiveness. The first part of the dissertation shows the impact of leader behavior on follower well-being in the context of transformational leadership. The second part goes beyond single leader behaviors and investigates the value-based alignment of two behaviors, namely vision communication and goal setting, and their effects on trust and leaders‘ effectiveness. Turning the lens, the final part sheds ...
