Core Self‐Evaluations in Germany: Validation of a German Measure and its Relationships with Career Success

The present study reports the results of a validation of a German version of the Core Self‐Evaluations Scale (CSES) and its relationships with career success. Data were collected in three occupational samples to address various aspects of validation. Our results confirm the proposed one‐factor structure of the scale as well as convergent, discriminant, criterion, and predictive validity. Furthermore, the German CSES shows incremental validity over the individual core traits (neuroticism, self‐esteem, self‐efficacy, and locus of control), the Big Five, and positive and negative affect. Thus, the German version of the Core Self‐Evaluations Scale is a reliable, valid, and economic measure for both research and practical applications. Furthermore, hypothesised relationships of core self‐evaluations with objective as well as subjective career success were confirmed. Possible explanations of these relationships are discussed. On présente dans cet article une étude de validation d'une version allemande de la Core Self‐Evaluation Scale (CSES) avec son rapport au succès professionnel. Les données ont été recueillies auprès d'échantillons relevant de trois métiers pour couvrir plusieurs aspects de la validation. Nos résultats confirment la structure unifactorielle attendue ainsi que les validités convergente, discriminante, prédictive et critérielle. En outre, la CSES allemande présente une validité incrémentielle pour le Big Five, les émotions positives et négatives et les traits centraux individuels (névrotisme, estime de soi, auto‐efficience et locus of control). La version allemande de la CSES est par conséquent un outil fidèle, valide et économique aussi bien pour la recherche que pour les applications pratiques. Sans compter qu'ont été confirmées les relations supposées des auto‐évaluations centrales avec le succès professionnel, qu'il soit objectif ou subjectif. On analyse les raisons possibles de ces relations.

Do chimpanzees anticipate an object’s weight? A field experiment on the kinematics of hammer-lifting movements in the nut-cracking Taï chimpanzees

When humans are about to manipulate an object, our brains use visual cues to recall an internal representation to predict its weight and scale the lifting force accordingly. Such a long-term force profile, formed through repeated experiences with similar objects, has been proposed to improve manipulative performance. Skillful object manipulation is crucial for many animals, particularly those that rely on tools for foraging. However, despite enduring interest in tool use in non-human animals, there has been very little investigation of their ability to form an expectation about an object’s weight. In this study, we tested whether wild chimpanzees use long-term force profiles to anticipate the weight of a nut-cracking hammer from its size. To this end, we conducted a field experiment presenting chimpanzees with natural wooden hammers and artificially hollowed, lighter hammers of the same size and external appearance. We used calibrated videos from camera traps to extract kinematic parameters of lifting movements. We found that, when lacking previous experience, chimpanzees lifted hollowed hammers with a higher acceleration than natural hammers (overshoot effect). After using a hammer to crack open one nut, chimpanzees tuned down the lifting acceleration for the hollowed hammers, but continued lifting natural hammers with the same acceleration. Our results show that chimpanzees anticipate the weight of an object using long-term force profiles and suggest that, similarly to humans, they use internal representations of weight to plan their lifting movements.     

Exaggeration is harder than understatement, but practice makes perfect!

Previous research on the fakeability of the Implicit Association Test (IAT) yielded inconsistent results. The present study simultaneously analyses several relevant factors: faking direction, type of instructions, and practice. Furthermore, it takes baseline individual differences into account. After a baseline assessment in a self-esteem IAT without faking instructions (t0), participants in the faking conditions then (t1) faked high or low scores without being provided with recommended strategies on how to do so (i.e., individual strategies). At t2 and t3, they were asked to fake the IAT after having received information on recommended faking strategies. At t4, faking direction was reversed. Without the recommended strategies, faking high scores was not possible, but faking low scores was. With the recommended strategies, participants needed additional practice to fake high scores. When faking directions were reversed, participants were successful without additional practice, suggesting a transfer in faking skills. In most of the faking attempts, faking success was moderated by individual differences in baseline implicit self-esteem. This suggests that the complex interplay of factors influencing faking success should be taken into account when considering the issue of fakeability of the IAT.     

The multinomial model of prospective memory: validity of ongoing-task parameters

The objective of this research was to provide additional experimental validation of the multinomial processing tree (MPT) model of event-based prospective memory (Smith & Bayen, 2004). In particular, the parameters that measure trial-type detection in the ongoing task were examined. In three experiments with different response instructions, event-based prospective memory tasks were embedded in ongoing color-matching tasks. The results support the validity of the MPT model, that is, manipulations of ongoing-task difficulty affected the ongoing-task parameters of the MPT model, while leaving the estimates for the prospective and the retrospective components of prospective memory unaffected.     

Überwachung mittels „elektronischer Fußfessel“

For forensic expert witnesses the introduction of electronic surveillance to the German penal code system raised new questions, such as the effects on relapse prevention. This paper presents international experiences about the effects of electronic tagging, especially on relapse prevention, and lists the advantages and disadvantages of this procedure. Also the recommendations for electronic tagging concerning a sexual offender who was repeatedly convicted and released after 10 years of imprisonment are described.     

The use of schematic knowledge about sources in source monitoring

Source monitoring refers to mental processes leading to attributions regarding the origin of information. We tested Johnson, Hashtroudi, and Lindsay's (1993) assumption that prior source-relevant knowledge is used in some source-monitoring tasks. In two experiments using different domains of schematic knowledge, two sources presented information that was expected for one source and somewhat unexpected for the other. In a later source-monitoring test, participants decided whether items had been presented by Source A, by Source B, or were new. The results of both experiments show that source identification is better for expected items than for somewhat unexpected items. Multinomial modeling analyses revealed that when participants do not remember the source of information, they guess that it was presented by the expected source. These results provide evidence for the claim that source monitoring can be based on prior knowledge and support a guessing hypothesis.
