The influence of red on impression formation in a job application context

Recent research has shown that the color red can influence psychological functioning. In the present research we tested the hypothesis that red influences impression formation related to another person’s abilities. We conducted three experiments examining the influence of red on the evaluation of male target persons. In Experiment 1, participants viewing red, relative to green, on the shirt of a person presented on a photograph perceived him to be less intelligent. This effect was strongest in a job application context compared to other contexts. In Experiment 2, focusing solely on the job application context, participants viewing red, relative to blue, on an applicants’ tie perceived him to have less earning and leadership potential. In Experiment 3, participants viewing red, relative to green, on a job applicants’ tie rated him as less likely to be hired, and perceptions of ability and leadership potential mediated this effect. Both the conceptual and applied implications of these findings are discussed.     

The two sides of goal intentions: Intention self-concordance and intention strength as predictors of physical activity

Objective: The present research introduces an extended conceptualisation of self-concordance, which is considered an attribute not only of goals, but also of goal intentions. Based on a corresponding operationalisation, we investigate the interplay of both intention strength and intention self-concordance in the prediction of physical activity.

Design: Data were taken from a longitudinal study of 134 obese people who were asked to fill out a questionnaire three times every six months.

Main measures: Physical activity and intention self-concordance were measured by validated scales. Intentions strength was assessed by an item typically employed in the extant literature.

Results: Logistic regression analyses and path analyses showed both intention strength and self-concordance to be significant predictors of changes in physical activity over time. Additional analyses found self-efficacy to be a significant predictor of intention strength and self-concordance; for outcome expectations this was not the case.

Conclusions: Findings support the idea that intention strength and self-concordance are two critical facets of a goal intention that need to be considered in the prediction of physical activity participation. Whereas intention strength refers to the degree of determination with which a goal intention is adopted, self-concordance rather captures the quality of this intention.     

Repetition of educational AIDS advertising affects attitudes

In educational AIDS campaigns, initiators often use advertisements to warn about the threat of AIDS. The present Internet study (N = 283) tested the assumption of an inverted U-shaped relationship between the number of educational AIDS advertisements in a magazine and the perceived threat of AIDS among different groups (i.e., homosexual men and heterosexual men and women). This expectation was primarily based on signaling theory, which assumes that recipients use repetition frequency as a cue for judgments about the message. Results provided support for the expected inverted U-curve.     

Vortex re-capturing and kinematics in human underwater undulatory swimming

To maximize swimming speed athletes copy fish undulatory swimming during the underwater period after start and turn. The anatomical limitations may lead to deviations and may enforce compensating strategies. This has been investigated by analyzing the kinematics of two national female swimmers while swimming in a still water pool. Additionally, the flow around and behind the swimmers was measured with the aid of time-resolved particle image velocimetry (TR-2D-PIV). As compared to fish, the swimmers used undulatory waves characterized by much higher Strouhal numbers but very similar amplitude distributions along the body and Froude efficiencies. Vortices generated in the region of strongly flexing joints are suitable to be used pedally to enhance propulsion (vortex re-capturing). Complementing studies using numerical and technical modeling will help us to probe the efficiency of observed mechanisms and further improvements of the human strategy.     

Die DPG-Praxis-Studie

All psychotherapeutic methods must be scientifically evaluated. Empirical evaluation of evidence is a prerequisite for acceptance as scientific psychotherapy as well as for payment by health insurance. Currently the psychotherapy methods accepted within the German health system (behavioural therapy, psychodynamic psychotherapy, and analytic psychotherapy) are reviewed by a governmental evaluation committee concerning evidence, necessity and cost-effectiveness. The DPG practice study has basically two aims: 1) to conduct a large naturalistic study to investigate effectiveness, sustainability and economic aspects of psychodynamic and analytic psychotherapy and 2) to offer a framework for psychoanalytic institutes, members, candidates or groups to realize own research ideas by collecting additional data within the study. The present article describes the background, main research questions, structure and design of the DPG practice study with regard to the evaluation questions.     

Nature against nurture: calcification in the right thalamus in a young man with anorexia nervosa and obsessive-compulsive personality disorder

This report describes the case of a young man with a large calcification in the right thalamus that was first diagnosed at 9 years of age. Case history reveals specific eating rituals and other obsessive-compulsive personality traits during the patient's childhood and adolescence, fulfilling diagnostic criteria of obsessive-compulsive personality disorder. After a critical life event the patient develops anorexia nervosa. We suggest that our case and further literature provide evidence for an involvement of specific thalamic structures, such as the dorsomedial nucleus, in the development of anorexia nervosa. Furthermore, the treatment of the patient by a combined psychotherapeutic and pharmacotherapeutic approach is described. We focus on the beneficial effect of the atypical antipsychotic olanzapine, which can induce weight gain by an increase of leptin levels.     

Gegenübertragungsdiagnostik in der Psychotherapie suizidaler Männer

The diagnosis of suicidality is an important challenge in psychotherapy: The threat of life has to be determined, decisions in differential therapy must be made and the therapeutical relationship must be established. The psychoanalytical contribution to the diagnostics of suicidality is the analysis of transference and countertransference phenomena, of "scenic" actions and of enactments between patient and therapist. By a systematic qualitative research method ("forming ideal types by understanding") 5 prototypical transference-/countertransference situations at the beginning of outpatient psychodynamic psychotherapy of suicidal men are identified and out of them 3 ideal types are constructed. The object-alienated ideal type with an avoidant transference and "weak", e.g. unemotional complementary countertransference appears to be a special problem. If aggression and strong attachment wishes toward the object come into the therapeutic relationship, this often is an indicator for the contacts’strength and can lead to deactualisation of suicidality. The results are discussed with and supported by methodically different publications on object relations orientated aspects of suicidality.     

Bidirektionale Optimalitätstheorie

Bidirectional Optimality Theory Summary. Optimality Theory as developed by Prince, Smolensky and others has been fruitfully applied to phonology, morphology, and syntax. The attempt to apply the ideas developed in these fields to the semantics/pragmatics interface necessitates the conception of a bidirectional OT. The main reason for assuming the idea of bidirectionality (combining expressive and interpretive optimization) derives from a number of phenomena which, on the one hand, demand the treatment of preferred interpretations, and, on the other hand, suggest to take into account the existence of blocking effects. In this article, some general motivation for the idea of bidirectionality is presented, the importance of this idea for the field of pragmatics (conversational implicature) is investigated, and some potential applications of bidirectional OT are outlined. Zusammenfassung. Die von Prince, Smolensky und anderen entwickelte Optimalitätstheorie (OT) hat ihre Fruchtbarkeit in den Bereichen Phonologie, Morphologie und Syntax zulänglich bewiesen. Der Versuch, die auf diesen Gebieten erarbeiteten Grundideen auf die Semantik/Pragmatik-Schnittstelle anzuwenden, führt zwingend auf das Konzept einer bidirektionalen OT. Der Hauptgrund für die Annahme von Bidirektionalität (Kombination von interpretativer und expressiver Optimierung) ergibt sich vor allem daraus, dass im genannten Bereich eine Reihe von Phänomenen existieren, die einerseits die Behandlung von vorgezogenen Interpretationen verlangen und andererseits zur Berücksichtigung von Blockierungseffekten auffordern. Die vorliegende Arbeit gibt eine allgemeine Motivation für Bidirektionalität, untersucht die Wirkungsweise von Bidirektionalität im Bereich der Pragmatik (konversationelle Implikaturen) und gibt eine Übersicht über potenzielle Anwendungen.
