Verbal proficiency as fitness indicator: Experimental and comparative research on the evolutionary psychology of language and verbal displays
(2011-10-26)
Summary: Recent research on the evolution of language and verbal displays (e.g., Miller, 1999, 2000a, 2000b, 2002) indicated that language is not only the result of natural selection but serves as a sexually-selected fitness indicator that is an adaptation showing an individual’s suitability as a reproductive mate. Thus, language could be placed within the framework of concepts such as the handicap principle (Zahavi, 1975). There are several reasons for this position: Many linguistic traits are highly heritable ...

Teaching quality in higher education: Do student evaluation of teaching questionnaires allow a reliable and valid assessment of teaching quality?
(2018-06-18)
Improving teaching quality is a relevant topic in society to nurture the students’ innate potential in the best possible way. One often applied tool for assessing teaching quality in higher education is student evaluations of teaching (SETs) that are used as a criterion for making important decisions in higher education such as employing teachers, distributing funds, and making changes in the curriculum. Despite their effect on decisions it is relatively unclear if SETs are a valid and reliable assessment of teaching ...

"Wenn die Welt keinen Wert auf einen legt"
(2014-06-02)
Wir leben in einer schnelllebigen unsicheren Welt. In einer Welt, in der fast jede Person schon einmal ein Gefühl von Wertlosigkeit und Ausgrenzung verspürt hat. Im vorliegenden an einer Schnittstelle zwischen Soziologie und Psychologie lokalisierten Dissertationsprojekt wird sich mit eben diesem aversiven Empfinden, sozial sowie gesellschaftlich überflüssig und ausgeschlossen zu sein, in Entstehung und möglichen Auswirkungen auseinandergesetzt. Dafür wurden eine deutschlandweite Telefon- und zwei experimentelle ...

Begleitpersonen in der stationären Kinderrehabilitation: Bedarf für psychologische Interventionen und Evaluation eines Betreuungsmodells (am Beispiel "Triple-P-Programm")
(2012-11-26)
Begleitpersonen in der stationären Kinderrehabilitation: Bedarf für psychologische Interventionen und Evaluation eines Betreuungsmodells (am Beispiel „Triple-P-Programm”)
Chronisch erkrankte Kinder im Vorschulalter, die eine stationäre Reha-Maßnahme absolvieren, werden üblicherweise von einer Bezugsperson (Elternteil oder nahe Verwandte) begleitet. Da diese sog. Begleitpersonen normalerweise nicht krank sind, sind psychologische Interventionen nicht vorgesehen. Dennoch hebt der VDR in seinem Rahmenkonzept hervor, ...

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 ...

Equivalence of Reading and Listening Comprehension Across Test Media
(2011-09-28)
Whether an ability test delivered on either paper or computer provides the same information is an important question in applied psychometrics. Besides the validity, it is also the fairness of a measure that is at stake if the test medium affects performance. This study provides a comprehensive review of existing equivalence research in the field of reading and listening comprehension in English as a foreign language and specifies factors that are likely to have an impact on equivalence. Taking into account these ...

Social Loafing in the Refugee Crisis: Information about Existing Initiatives Decreases Willingness to Help
(2017-05-11)
In light of the European refugee situation, we investigate how information about others’ support influences individuals’ willingness to help. When individuals see information about other people supporting refugees, they may either be influenced by a descriptive norm, and act accordingly. Alternatively, they may perceive that others are already doing the job, and thus engage in social loafing. In an experiment (N = 132), we tested these competing predictions. Specifically, participants were exposed to a map of Germany ...

Distributing mathematical practice of third and seventh graders: Applicability of the spacing effect in the classroom
(2018-10-23)
We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day. In the distributed condition, they worked on one practice set per day for 3 consecutive days. Bayesian analyses of the performance in two follow‐up tests 1 and 6 weeks after ...

Reading a short story changes children’s sustainable behavior in a resource dilemma
(2019-12-02)
Fostering sustainable behavior in children and adolescents should be a central aim of today’s education. Even though the interplay of factors affecting sustainable behavior is complex, simple interventions can be effective too. In the current study, 10-year-olds (N = 132) were read a short story about two foresters who collectively used a forest to gain timber, facing a resource dilemma that involved striving for maximizing their individual profit while sustaining the forest. In the story, the foresters solved the ...

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 ...
