Abstract. Neurocognitive deficits in patients with mental disorders are partially due to secondary influences. “Stereotype threat” denotes the phenomenon that performance is compromised when a participant is confronted with a devaluing stereotype. The present study examined the impact of stereotype threat on neuropsychological performance in schizophrenia. Seventy-seven participants with a self-reported diagnosis of schizophrenia were randomly assigned to either an experimental condition involving stereotype threat activation or a control condition in an online study. Participants completed memory and attention tests as well as questionnaires on motivation, self-efficacy expectations, cognitive complaints, and self-stigmatization. Contrary to our prediction, the two groups showed no significant differences regarding neuropsychological performance and self-report measures. Limitations, such as a possibly too weak threat cue, are discussed and recommendations for future studies are outlined.

Abstract. The Dark Triad is a constellation of three antisocial personality traits: Machiavellianism, narcissism, and psychopathy. Recently, researchers have introduced a “Dark Tetrad” that includes subclinical sadism, although others suggest considerable overlap between psychopathy and sadism. To clarify the position of sadism within the Dark Triad, an online study was conducted with 615 university students. Exploratory factor analysis revealed that a six-factor solution fit the data best, representing Machiavellianism, psychopathy, physical sadism, verbal sadism, narcissism, and vicarious sadism. Furthermore, convergent validity was supported through sadism’s correlations with the HEXACO personality traits. The results support sadism’s inclusion within the Dark Tetrad as a unique construct but with some conceptual overlap with psychopathy.

The present research aimed at constructing a questionnaire measuring overclaiming tendencies (VOC-T-bias) as an indicator of self-enhancement. An approach was used which also allows estimation of a score for vocabulary knowledge, the accuracy index (VOC-T-accuracy), using signal detection theory. For construction purposes, an online study was conducted with N = 1,176 participants. The resulting questionnaire, named Vocabulary and Overclaiming – Test (VOC-T) was investigated with regard to its psychometric properties in two further studies. Study 2 used data from a population representative sample (N = 527), and Study 3 was another online survey (N = 933). Results show that reliability estimates were satisfactory for the VOC-T-bias index and the VOC-T-accuracy index. Overclaiming did not correlate with knowledge, but it was sensitive to self-enhancement supporting the construct validity of the test scores. The VOC-T-accuracy index in turn covaried with general knowledge and even more so with verbal knowledge, which also supports construct validity. Moreover, the VOC-T-accuracy index had a meaningful correlation with age in both validation studies. All in all, the psychometric properties can be regarded as sufficient to recommend the VOC-T for research purposes.

There is a critical need for the public to have trusted sources of vaccine information. A longitudinal online study assessed trust in COVID-19 vaccine information from 10 sources. A factor analysis for data reduction revealed two factors. The first factor contained politically conservative sources (PCS) of information. The second factor included eight news sources representing mainstream sources (MS). Multivariable logistic regression models were used. Trust in Dr. Fauci was also examined. High trust in MS was associated with intention to encourage family members to get COVID-19 vaccines, altruistic beliefs that more vulnerable people should have vaccine priority, and belief that racial minorities with higher rates of COVID-19 deaths should have priority. High trust in PCS was associated with intention to discourage friends from getting vaccinated. Higher trust in PCS was also associated with participants more likely to disagree that minorities with higher rates of COVID-19 deaths should have priority for a vaccine. High trust in Dr. Fauci as a source of COVID-19 vaccine information was associated with factors similar to high trust in MS. Fair, equitable, and transparent access and distribution are essential to ensure trust in public health systems’ abilities to serve the population.

AbstractThis study proposes an innovative blended flipped and online mode for PBL-flipped and PBL-online study, a PBL-blended format of instruction. The study determines whether different pedagogical strategies – PBL-flipped, PBL-online and PBL-blended – influence the validation results for the ARCS model and the PBL learning outcomes. The study population consists of 116 students who use the general education Information and Literacy Ethics digital materials for higher education produced by the Ministry of Education in Taiwan. The quantitative and qualitative results demonstrate that the paths in the ARCS model are all statistically significant for the three methods of instruction and there are no significant differences among the three methods of instruction in terms of class participation and learning scores. However, there is a very noticeable improvement in the PBL learning process in the aspects of reliable leadership and group collaboration learning in blended groups. Self-directed learning is also enhanced and negative learning attitudes are significantly reduced in blended groups. The study demonstrates that the proposed PBL-blended teaching mode is a more efficient and effective way of promoting PBL learning in information literacy courses.

We investigate in-service teachers’ reasons for trust and distrust in educational research compared to research in general. Building on previous research on a so-called “smart but evil” stereotype regarding educational researchers, three sets of confirmatory hypotheses were preregistered. First, we expected that teachers would emphasize expertise—as compared with benevolence and integrity—as a stronger reason for trust in educational researchers. Moreover, we expected that this pattern would not only apply to educational researchers, but that it would generalize to researchers in general. Furthermore, we hypothesized that the pattern could also be found in the general population. Following a pilot study aiming to establish the validity of our measures (German general population sample; N = 504), hypotheses were tested in an online study with N = 414 randomly sampled German in-service teachers. Using the Bayesian informative hypothesis evaluation framework, we found empirical support for five of our six preregistered hypotheses.

AbstractPersonalizing gameful applications is essential to account for interpersonal differences in the perception of gameful design elements. Considering that an increasing number of people lead sedentary lifestyles, using personalized gameful applications to encourage physical activity is a particularly relevant domain. In this article, we investigate behavior change intentions and Hexad user types as factors to personalize gameful fitness applications. We first explored the potential of these two factors by analyzing differences in the perceived persuasiveness of gameful design elements using a storyboards-based online study ($$N=178$$ N = 178 ). Our results show several significant effects regarding both factors and thus support the usefulness of them in explaining perceptual differences. Based on these findings, we implemented “Endless Universe,” a personalized gameful application encouraging physical activity on a treadmill. We used the system in a laboratory study ($$N=20$$ N = 20 ) to study actual effects of personalization on the users’ performance, enjoyment and affective experiences. While we did not find effects on the immediate performance of users, positive effects on user experience-related measures were found. The results of this study support the relevance of behavior change intentions and Hexad user types for personalizing gameful fitness systems further.
