Two studies investigated the different contribution of positive and negative associations to the size of the Implicit Association Test (IAT) effect. A Many-Facet Rasch Measurement analysis was applied for the purpose. Across different IATs (Race and Weight) and different groups of respondents (White, Normal weight, and Obese people) we observed that positive words increase the IAT effect whereas negative words tend to decrease it. Results suggest that the IAT is influenced by a positive associations primacy effect. As a consequence, we argue that researchers should be careful when interpreting IAT effects as a measure of implicit prejudice.

The Impact

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.

Rasch Measurement

Zusammenfassung. Leistungsbeurteilungen unterliegen einer Reihe von Urteilsfehlern, die ihre Genauigkeit und Validität erheblich mindern können. Ein besonders kritischer Urteilsfehler ist die Tendenz zur Strenge bzw. Milde. In der vorliegenden Arbeit wird mit der Multifacetten-Rasch-Analyse (“many-facet Rasch measurement“; Linacre, 1989 ; Linacre & Wright, 2002 ) ein Item-Response-Modell vorgestellt, das Messungen der Strenge bzw. Milde eines jeden Beurteilers erlaubt und die ermittelten Strengemaße zusammen mit den Fähigkeitsmaßen der beurteilten Personen und den Schwierigkeitsmaßen der Aufgaben oder Beurteilungskriterien in einen gemeinsamen Bezugsrahmen stellt. Das Modell ermöglicht ferner eine um die Strenge der Beurteiler korrigierte Leistungsmessung. Mittels dieses Ansatzes werden im Rahmen des “Test Deutsch als Fremdsprache“ (TestDaF) Beurteilungen analysiert, die je 2 von insgesamt 29 Beurteilern zu Leistungen von 1359 Pbn im schriftlichen Ausdruck nach 3 Kriterien abgegeben haben. Die Gruppe der Beurteiler erweist sich als sehr heterogen, so dass eine Strengekorrektur der Urteile geboten ist. Abschließend werden verschiedene Implikationen des Multifacetten-Rasch-Modells für die Evaluation von Leistungsbeurteilungen diskutiert.

Antisocial Personality Traits

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.
