Challenges in detecting proximal effects of existential threat on lie detection accuracy
(2022-06-14)
The present work documents our investigation of proximal (i.e., immediate) effects of existential threat on the process of lie detection. Specifically, we hypothesized that lie detection accuracy will be higher in a mortality salience (MS) condition compared with the control condition. In two lab-based studies (N = 120; N = 109) and one internet study (N = 1294), we did not find any evidence for this hypothesis, that is, MS effects on lie detection accuracy were constantly not significant. However, these null findings ...

Effects of task interruptions caused by notifications from communication applications on strain and performance
(2023-06-06)
Objectives:
To examine the effect of automatic communication notifications on performance and strain. Because of the benefits of communication, we expected this effect to be moderated by fear of missing out (FoMO) and social norms of responsiveness, expressed in the experience of telepressure.
Methods:
A field experiment (N = 247) was conducted in which participants in the experimental group disabled their notification during 1 day (N = 124).
Results:
The findings revealed that a reduction of notification-caused ...

Is It the Judge, the Sender, or Just the Individual Message? Disentangling Person and Message Effects on Variation in Lie-Detection Judgments
(2023-02-15)
Research suggests that people differ more in their ability to lie than in their ability to detect lies. However, because studies have not treated senders and messages as separate entities, it is unclear whether some senders are generally more transparent than others or whether individual messages differ in their transparency of veracity regardless of senders. Variance attributable to judges, senders, and messages was estimated simultaneously using multiple messages from each sender (totaling more than 45,000 judgments). ...

The correlation between honesty-humility and attitude toward counterfeit luxury
(2023-10-18)
This research focuses on the relation between Honesty-Humility and attitude toward counterfeit luxury. Honesty-Humility is defined as the tendency to be fair in dealing with others. Given that the act of knowingly purchasing a counterfeit could be judged as morally questionable, immodest, and manipulative, we predicted that people lower in Honesty-Humility would report more positive attitudes toward counterfeit luxury. Given that related research from behavioral research revealed Honesty-Humility to be the key predictor ...

Free to See the Big Picture: Autonomy Increases Abstractness of Action Identification
(2023-10-10)
People sometimes feel autonomous—free to choose and able to control their actions; at other times, they feel restricted in what they can do and what the outcome will be. Based on Action Identification Theory, the present work examines whether autonomy influences how abstractly actions are represented. In 6 studies, high (vs. low) autonomy increased abstractness of action identification. Participants selected more abstract (vs. concrete) redescriptions of actions when they imagined wanting (vs. having) to perform these ...

Fostering diagnostic competence in prospective mathematics elementary teachers through epistemic activities
(2023-12-21)
Research on fostering teachers’ diagnostic competence and thinking has become increasingly important. To this end, research has already identified several aspects of effective fostering of teachers’ diagnostic competence. One of the aspects is assignment of the role as a teacher in interventions but, so far, assignment of the role of student has hardly been considered. Based on a model of the diagnostic thinking process, this paper operationalizes the role of the student by solving specific tasks and the role of the ...

Mental health and stress level of Ukrainians seeking psychological help online
(2023-11-04)
Due to the Russian invasion of Ukraine on February 24th, 2022, more than 8 million Ukrainians have been displaced from their homes. Ukrainians exposed to armed conflict and migration are likely to have low levels of mental health status and seek help. We provide a uniform quantitative assessment of the mental health conditions of Ukrainians seeking help soon after the invasion and resettlement. We screen the mental well-being and psychological distress of 1165 refugees, migrants, internally displaced, and non-displaced ...

Model Specification Searches in Structural Equation Modeling Using Bee Swarm Optimization
(2023-03-29)
Metaheuristics are optimization algorithms that efficiently solve a variety of complex combinatorial problems. In psychological research, metaheuristics have been applied in short-scale construction and model specification search. In the present study, we propose a bee swarm optimization (BSO) algorithm to explore the structure underlying a psychological measurement instrument. The algorithm assigns items to an unknown number of nested factors in a confirmatory bifactor model, while simultaneously selecting items for ...

Articulation posture influences pitch during singing imagery
(2023-05-03)
Facial muscle activity contributes to singing and to articulation: in articulation, mouth shape can alter vowel identity; and in singing, facial movement correlates with pitch changes. Here, we examine whether mouth posture causally influences pitch during singing imagery. Based on perception–action theories and embodied cognition theories, we predict that mouth posture influences pitch judgments even when no overt utterances are produced. In two experiments (total N = 160), mouth posture was manipulated to resemble ...

Psychotherapie wirkt
(2024-01-08)
Psychotherapie ist eine kooperative und individualisierte Behandlung zur Förderung der psychischen Gesundheit, die sich in (post-)modernen Gesellschaften weiterentwickelt. Psychotherapieerfolg umfasst ein breites Spektrum von Kriterien, wie beispielsweise die Verringerung von symptombezogenem Leidensdruck sowie die Förderung von Wohlbefinden, persönlichen Werten, Stärken und psychosozialer Partizipation. Es liegen umfangreiche metaanalytische Belege dafür vor, dass Psychotherapie bei den häufigsten psychischen Störungen ...
