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.     

Ambient Green and Creativity

This research examined an important applied question: whether viewing ambient green (relative to red) on the wall of a workspace would facilitate creativity. A methodologically sound experiment revealed no influence of green on creativity. Care must be taken when interpreting a null result, but these data do not provide support for the presence of a relation between ambient green and creativity. This research also highlights the need for more research in the area of ambient color and psychological functioning, and the need for caution regarding the tendency to move to real-world recommendations before a firm empirical base is established.     

Autonomy,decisions, and free will

Can humans make decisions? Can machines? What ethical questions arise from using robotics in the education of children? Or in elderly care? These were some of the topics of the interdisciplinary college (IK), which took place from the 25th of March to the 1st of April in Günne, next to Lake Möhne. During this one-week spring school, more than 40 well-known lecturers from around the globe gave 170 participants an insight into a cornucopia of topics surrounding “autonomy, decisions, and free will”.     

Stressor exposure produces long-term reductions in antigen-specific T and B cell responses

Exposure to an acute laboratory stressor at the time of keyhole limpet hemocyanin (KLH) immunization results in a long-term suppression in circulating anti-KLH antibody. The mechanism for the stress-induced reduction in anti-KLH immunoglobulin (Ig) remains unknown. Given that the generation of anti-KLH antibody requires T cell help, we hypothesize that stress reduces the proliferation of anti-KLH T cells, thus leading to a reduction in anti-KLH antibody. The present studies examined the effect of tail shock stress (100, 1.6 mA, 5-s, 60 s ITI) on the KLH specific T cell response. Fischer F344 rats were immunized either intraperitoneally (i.p.) or subcutaneously (s.c.) at the base of the tail with 200 microg KLH, and exposed to inescapable tail shock (IS) or remained in their home cages (HCC). T cell proliferation after KLH restimulation, but not ConA, was markedly suppressed in IS animals in both the spleen after i.p. immunization and the draining lymph nodes after s.c. immunization. Other secondary lymphoid cells did not differ in their proliferative capacity. Anti-KLH IgG, IgG1 and IgG2a, but not anti-KLH IgM serum levels were significantly suppressed. These data support the conclusion that stress suppresses the generation of antigen specific T cells. In addition, the methods employed in the current study allow the isolation of the site of the acquired T cell immune response, making it possible to further elucidate the cellular mechanisms that contribute to stress-induced modulation of the antigen-specific acquired immune response.     

Directionality of affective priming: effects of trait anxiety and activation level

Among the most influential models of automatic affective processing is the spreading activation account (Fazio, Sanbonmatsu, Powell, & Kardes, 1986). However, investigations of this model by different research groups using the pronunciation task in an affective priming paradigm yielded contradictory results. Whereas one research group reported congruency effects, another obtained reversed priming effects (contrast effects), and still another found null effects. In Experiment 1, we were able to show an influence of trait anxiety on the direction of the affective priming effect. By using a multiple priming paradigm in Experiment 2, we were able to link the occurrence of reversed priming effects to increased levels of activation of affective representations. We propose that this relation might underlie the influence of trait anxiety on the direction of affective priming effects. Both experiments indicate that automatic evaluation in an affective network is substantially moderated by personality traits and activation level.     

Sex differences in the perception of touching

Sex differences in the perception of touching were investigated by having 25 male and 25 female college students rate how likeable a touch would be under different conditions. The women produced a more favorable affect than the men when they touched, and women were perceived as liking to be touched more than men. Perception of touching in general was correlated positively with Self-esteem for men, negatively with Machiavellianism for women, and positively with Trust for women. Results were discussed in terms of traditional sex-typing of touching behavior.     

The decrement in conditioned fear with increased trials of simultaneous conditioning is not specific to the simultaneous procedure

Three experiments using a conditioned punishment paradigm with rat subjects examined the possibility that the nonmonotonic acquisition function previously found to characterize simultaneous conditioning was due to the noninformative nature of the conditioned stimulus (CS). In Experiment 1 the suppressive effects of a CS previously presented with an unconditioned stimulus (US) in a simultaneous and forward (informative) manner were compared following 20 and an additional 60 conditioning trials. Excitatory conditioning similarly diminished with increased trials for both the simultaneous and forward procedures. Experiment 2 employed a between-groups design. Simultaneous, forward, and trace conditioning procedures were compared following 20 or 100 trials. Each of the three 100-trial groups showed less resistance to extinction than their 20-trial counterparts. Experiment 3 determined that the decrement in excitatory conditioning for the 100-trial groups was not due to the greater number of US presentations, per se, but rather to the number of CS-US pairings. The nonmonotonic acquisition function observed with all three conditioning procedures indicated that informational factors were not responsible for the decrement observed in simultaneous conditioning. The pattern of results suggested that subjects receiving extended conditioning trials were better able to discriminate between training and testing.
