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 ...

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 ...

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 ...

Wie kann Reden helfen?
(2019-09-12)
Psychotherapie gilt tradionell als „talking cure“ oder „Redekur“ (Breuer & Freud, 1895, S. 50) – als Heilverfahren also, das wesentlich über einen „Austausch von Worten“ (Freud, 1916-17, S. 43) operiert. Diese Zuschreibung ist allerdings ebenso gängig wie diffus, insofern 1. die konkreten Mechanismen, über die sprachliche Vollzüge therapeutische Veränderungsprozesse induzieren, in vielen Hinsichten unklar sind, und 2. der systematische Ort der Sprache innerhalb des therapeutischen Prozesses – etwa in Relation zu ...
