Effectiveness and context dependency of social norm interventions: five field experiments on nudging pro-environmental and pro-social behavior
(2024-06-26)
Social norm interventions hold the potential to change people’s behavior. Five field experiments (N = 1,163) examined the effects of a simple and easily realizable social norm nudge based on the social media format “Be like Bill.” The nudge consisted of a stick figure named Toni that communicated descriptive and injunctive norms regarding pro-environmental or pro-social behaviors. Nudge conditions were compared to no-intervention control conditions. Experiment 1 (N = 179) focused on paper towel consumption in a women’s ...

Wer kann, der coacht: Ein Instrument zur Messung interpersoneller Coach-Fähigkeiten
(2021-06-01)
Es wird ein aus der Psychotherapieforschung stammendes, an Coaching adaptiertes Ratingmanual zur Messung interpersoneller Fähigkeiten vorgestellt. Es wurden Ratings für 18 Audioaufnahmen von dyadischen Coachingsitzungen von neun Coaches-in-Weiterbildung erstellt, die zu Beginn der Weiterbildung und ein Jahr später durchgeführt wurden. Das interpersonelle Verhalten und die Entwicklung der Kompetenzen von zwei Coaches-in-Weiterbildung werden exemplarisch dargestellt. Die Autorinnen ziehen das Fazit, dass sich das ...

Learning with a double-edged sword? beneficial and detrimental effects of learning tests—taking a first look at linkages among tests, later learning outcomes, stress perceptions, and intelligence
(2021-08-31)
It has often been shown that tests as intentionally hindered and difficult learning tasks increase long-term learning compared to easier tasks. Previous work additionally indicated that higher intelligence might serve as a prerequisite for such beneficial effects of tests. Nevertheless, despite their long-term learning effects, tests were also found to be evaluated as more negative and to lead to more stress and anxiety compared to easier control tasks. Stress and anxiety, in turn, often yield detrimental effects on ...

Validation of cognitive load during inquiry-based learning with multimedia scaffolds using subjective measurement and eye movements
(2021-08-31)
Subject-method barriers and cognitive load (CL) of students have a particular importance in the complex learning process of scientific inquiry. In this work, we investigate the valid measurement of CL as well as different scaffolds to reduce it during experimentation. Specifically, we examine the validity of a subjective measurement instrument to assess CL [in extraneous cognitive load (ECL), intrinsic cognitive load, and germane cognitive load (GCL)] during the use of multimedia scaffolds in the planning phase of ...

Flexible Adaptation of Leader Behavior
(2021-06-01)
Based on the model of ambidextrous leadership, we investigated the impact of flexible adaptation of leader behavior, that is, opening and closing leader behaviors, on innovative performance in a laboratory experiment. Leader behaviors were manipulated with confederates attending to one participant showing either no leadership, a sequential, or a flexible application of opening and closing leader behaviors. We hypothesized that flexible adaptation leads to better innovation performance. N = 93 participants took part ...

Depression, Race-Based Bias, and Judgements of Veracity
(2023-07-26)
The depressive realism hypothesis suggests that depressed individuals have a more realistic perception than nondepressed. Most studies depict the effects of depressive realism on self-perceptions. However, some lie detection studies suggest the effects of depressive realism on the perception of others. Our study investigated the hypothesis that individuals with subclinical depression levels (dysphoric) show a heightened accuracy in lie detection and a lower truth bias. Furthermore, we expected these effects to be ...

The Road to Hell Is Paved With Good Intentions: How Common Practices in Scale Construction Hurt Validity
(2022-09-29)
Sound scale construction is pivotal to the measurement of psychological constructs. Common item sampling procedures emphasize aspects of reliability to the disadvantage of aspects of validity, which are less tangible. We use a health knowledge test as an example to demonstrate how item sampling strategies that focus on either factor saturation or construct coverage influence scale composition and demonstrate how to find a trade-off between these two opposing needs. More specifically, we compile three 75-item health ...

Integrative-interpersonal dynamic therapy for poststroke depression (INID): study protocol of a randomised controlled pilot trial
(2023-08-08)
Introduction Depression is the most frequent psychiatric disorder following stroke, affecting about one-third of stroke survivors. Patients experience poorer recovery, lower quality of life and higher mortality compared with stroke survivors without depression. Despite these well-known malign consequences, poststroke depression (PSD) is regarded underdiagnosed and undertreated. Evidence of beneficial effects of psychotherapy to treat PSD remains scarce and inconclusive and is limited by heterogeneity in design, content ...

Evaluating the role of maladaptive personality traits in schema therapy and cognitive behavioural therapy for depression
(2022-05-10)
Background: Advancements in the treatment of depression are pivotal due to high levels of non-response and relapse. This study evaluated the role of personality pathology in the treatment of depression by testing whether maladaptive personality traits (1) predict changes in depression over treatment or vice versa, (2) change themselves over treatment, (3) change differentially depending on treatment with schema therapy (ST) or cognitive behavioural therapy (CBT), and (4) moderate the effectiveness of these ...

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 ...
