Das offene Selbstgespräch des Teampartners - Einfluss auf die wahrgenommene Kompetenz und die eigene Anstrengungsbereitschaft

Einleitung und Fragestellung In der Forschung zum Selbstgespräch im Sport dominiert die Frage nach dessen Wir-kung auf die Leistung. Der Einfluss des während der Leistungserbringung geäußerten Selbstgesprächs auf (un-)beteiligte Personen (z.B. Zuschauer, Gegenspieler oder Dop-pelpartner) wurde bislang kaum untersucht. Van Raalte, Brewer, Cornelius und Petitpas (2006) konnten immerhin zeigen, dass Zuschauer einen Tennisspieler als kompetenter einschätzen, wenn er in einem Laborexperiment mit positivem statt mit negativem Selbst-gespräch gezeigt wurde. In unserer Studie stehen Dyaden im Zentrum, in der eine Person eine andere beobach-tet, die mit sich selbst spricht. Untersucht wird, ob bei einer additiven Teamaufgabe sol-che Beobachtungen einen Effekt auf die Kompetenzeinschätzung und die Anstren-gungsbereitschaft haben. Es wird vermutet, dass die beobachtende Person dann eine höhere Anstrengungsbereitschaft (AV) zeigt, wenn sie einen Teampartner mit positivem Selbstgespräch (UV) beobachtet, da sie ihren Partner als kompetenter einschätzt und diese Einschätzung als Mediator wirkt. Methode Es wurde ein randomisierter Zweigruppen-Versuchsplan mit zwei Experimentalgruppen (je n=20) durchgeführt. Das Treatment bestand aus einem Video, das den (jeweils identi-schen) Teampartner bei der Bewältigung der zu absolvierenden visuomotorisch-koordinativen Testaufgabe zeigt (Test 2HAND des Wiener Testsystems). Das Video wur-de abhängig von der Gruppenzugehörigkeit mit negativen respektive positiven Selbstge-sprächsaussagen unterlegt. Die Mediatorvariable wahrgenommene Kompetenz wurde mittels eines Fragebogens erhoben, der in Anlehnung an Van Raalte et al. (2006) entwi-ckelt wurde. Das Vorgehen zur Erhebung der abhängigen Variable Anstrengungsbereit-schaft wurde von Ohlert (2009) übernommen: Die Probanden erhielten die Möglichkeit, sich auf die spätere Testphase vorzubereiten. Erfasst wurde dabei die Zeit, die sie für die Vorbereitung in Anspruch nahmen, und die Genauigkeit, mit der sie eine Reihe von Aufwärmaufgaben absolvierten. Ergebnisse Die Datenerhebung wurde soeben abgeschlossen. Die Ergebnisse der noch ausstehen-den regressionsanalytischen Auswertung werden auf der Tagung präsentiert. Literatur Ohlert, J. (2009).

Das offene Selbstgespräch in Dyaden: Dessen Zusammenhang mit Selbstdarstellungstendenzen und Einfluss auf den Partner

Ausgangslage und Fragestellung In der Forschung zum Selbstgespräch im Sport dominiert die Frage nach dessen Auswir-kungen auf die sprechende Person selber. Gemäss Diaz (1992) besitzt das offene Selbstgespräch aber neben der individuell-regulatorischen auch eine sozial-kommunikative Funktion. Diese sozial-kommunikative Funktion und der damit verbunde-ne Einfluss des Selbstgesprächs auf Beobachter wurden in der Sportwissenschaft bisher nur marginal untersucht (z.B. Gould & Weiss, 1981; Van Raalte, Brewer, Cornelius & Pe-titpas, 2006). Im angestrebten Forschungsvorhaben sollen zwei Fragen geklärt werden: Steht das of-fene, während dem Wettkampf geäusserte Selbstgespräch eines Athleten in Zusammen-hang mit dessen Selbstdarstellung? Beeinflusst das offene Selbstgespräch eines Athle-ten den Dyadenpartner und wie sie sich gegenseitig wahrnehmen? Methode Es werden Doppelpartien im Badminton per Videokamera aufgezeichnet. Mittels einer Korrelationsanalyse soll überprüft werden, ob die so erhobenen Selbstgesprächsaussa-gen mit dem Persönlichkeitsmerkmal „Selbstdarstellung“ der Probanden zusammenhän-gen. Nach Spielschluss werden die Probanden entsprechend eines video-stimulierten Fremdkonfrontationsinterviews mit Spielausschnitten konfrontiert, die offenes Selbstge-spräch ihres Dyadenpartners enthalten. Sie werden dabei nach ihren Kognitionen sowie Emotionen gefragt, die sie während der entsprechenden Spielsituation erlebten. Aktuelle Fragen Welcher Fragebogen zur Erhebung des Persönlichkeitsmerkmals „Selbstdarstellung“ soll Verwendung finden? Zur Auswahl steht ein noch zu übersetzender, validierter, engli-scher und sportspezifischer Fragebogen und die Verwendung eines deutschen Frage-bogens, der habituelle Selbstdarstellungstechniken im Allgemeinen erhebt. Wie soll beim video-stimulierten Fremdkonfrontationsinterview vorgegangen werden? Werden den Probanden z.B. das ganze Spiel oder nur ausgewählte Ausschnitte gezeigt, in denen offenes Selbstgespräch vorkommt? Wie zeitnah muss das Interview durchge-führt werden? Literatur Diaz, R.

Effects of overt self-­talk on team partners’ other-efficacy and performance in a golf putting task

Introduction According to Lent and Lopez’ (2002) tripartite view of efficacy beliefs, members of a team form beliefs about the efficacy of their team partners. This other-efficacy belief can influence individual performance as shown by Dunlop, Beatty, and Beauchamp (2011) in their experimental study using manipulated performance feedback to alter other-efficacy beliefs. Participants holding favorable other-efficacy beliefs outperformed those with lower other--‐efficacy beliefs. Antecedents of such other-efficacy beliefs are amongst others perceptions regarding motivation and psychological factors of the partner (Jackson, Knapp, & Beauchamp, 2008). Overt self-talk could be interpreted as the manifestation of such motivational or psychological factors. In line with this assumption, in an experimental study using dubbed videos of the same segment of a tennis match, Van Raalte, Brewer, Cornelius, and Petitpas (2006) found that players were perceived more favorably (e.g., more concentrated, and of higher ability levels) when shown with dubbed positive self-talk as compared to dubbed negative or no dubbed self--‐talk. Objectives The aim of the study was to examine the possible effects of a confederate’s overt self-talk on participants’ other-efficacy beliefs and performance in a team setting. Method In a laboratory experiment (between-subjects, pre-post-test design, matched by pretest performance) 89 undergraduate students (female = 35, M = 20.81 years, SD = 2.34) participated in a golf putting task together with a confederate (same gender groups). Depending on the experimental condition (positive, negative, or no self-talk), the confederate commented his or her putts according to a self-talk script. Bogus performance feedback assured that the performance of the confederate was held constant. Performance was measured as the distance to the center of the target, other-efficacy by a questionnaire. Results The data collection has just finished and the results of repeated measures analyses of variance will be presented and discussed at the congress. We expect to find higher other-efficacy beliefs and better individual performance in the positive self-talk condition. References Dunlop, W.L., Beatty, D.J., & Beauchamp, M.R. (2011).

Direct democracy and political trust: Enhancing trust, initiating distrust–or both?

This study investigates the relationship between direct democracy and political trust. We suggest a solution to the controversy in research centering on positive versus negative effects of direct democracy by analytically differentiating between the availability of direct democratic rights and the actual use of those rights. Theoretically, greater availability of direct democratic rights may enhance political trust by increasing citizens’ perception that political authorities can be controlled as well as by incentivizing political authorities to act trustworthily. In contrast, the actual use of the corresponding direct democratic instruments may initiate distrust as it signals to citizens that political authorities do not act in the public’s interest. We test both hypotheses for the very first time with sub-national data of Switzerland. The empirical results seem to support our theoretical arguments.

Identification of gunshots to the head by detection of RNA in backspatter primarily expressed in brain tissue

Traces of backspatter recovered from the inside of the barrel of a gun that was used to deliver suicidal or homicidal contact shots may be a source of valuable forensic evidence and first systematic investigations of the persistence of victim DNA from inside firearms have been presented. The aim of the present study was to include victim RNA in such analyses to determine the origin of tissues in addition and parallel to standard DNA profiling for forensic identification purposes. In a first step, suitable mRNA (C1orf61) and micro-RNAs (miR-124a and miR-124*) that are primarily expressed in brain tissue were selected from potential candidates and confirmed using quantitative PCR (qPCR). Secondly, a co-extraction procedure for RNA and DNA was established and brain differentiability of the selected RNAs was demonstrated via qPCR using samples from experimental shots at ballistic models. In a third step, this procedure was successfully applied to analyse samples from real casework comprising eight cases of suicidal contact shots. In this pilot study, we are first to report the possibility of co-extracting mRNA, miRNA and DNA from ballistic trace samples collected from the inside of firearms and we demonstrate that RNA and DNA based analyses can be performed in parallel to produce informative and highly complementary evidence.

Persistence of biological traces at inside parts of a firearm from a case of multiple familial homicide

Backspatter from wounds caused by contact shots against a biological target had before been shown to be propelled into firearms' barrels where they can persist and be retrieved from as relevant forensic evidence. Herein, that insight was applied to the investigation of a case of multiple familial homicide with a firearm. Samples of backspatter were collected from the firearm using DNA-free swabs. DNA was extracted from the swabs, and 16 STR systems were PCR-amplified to generate DNA profiles of all victims shot by the firearm. The quality of the resulting DNA profiles was sufficient to exclude the perpetrator as donor and to differentiate the three closely related victims thereby proving that all three victims had been shot by the same firearm from very close or contact distance. A key insight gained from this case was that not only a firearms' barrel inside but other inner surfaces may be charged with profilable DNA.

The 'triple contrast' method in experimental wound ballistics and backspatter analysis.

In practical forensic casework, backspatter recovered from shooters' hands can be an indicator of self-inflicted gunshot wounds to the head. In such cases, backspatter retrieved from inside the barrel indicates that the weapon found at the death scene was involved in causing the injury to the head. However, systematic research on the aspects conditioning presence, amount and specific patterns of backspatter is lacking so far. Herein, a new concept of backspatter investigation is presented, comprising staining technique, weapon and target medium: the 'triple contrast method' was developed, tested and is introduced for experimental backspatter analysis. First, mixtures of various proportions of acrylic paint for optical detection, barium sulphate for radiocontrast imaging in computed tomography and fresh human blood for PCR-based DNA profiling were generated (triple mixture) and tested for DNA quantification and short tandem repeat (STR) typing success. All tested mixtures yielded sufficient DNA that produced full STR profiles suitable for forensic identification. Then, for backspatter analysis, sealed foil bags containing the triple mixture were attached to plastic bottles filled with 10 % ballistic gelatine and covered by a 2-3-mm layer of silicone. To simulate backspatter, close contact shots were fired at these models. Endoscopy of the barrel inside revealed coloured backspatter containing typable DNA and radiographic imaging showed a contrasted bullet path in the gelatine. Cross sections of the gelatine core exhibited cracks and fissures stained by the acrylic paint facilitating wound ballistic analysis.

Distinct characteristics of e13a2 versus e14a2 BCR-ABL1 driven chronic myeloid leukemia under first-line therapy with imatinib

The vast majority of chronic myeloid leukemia patients express a BCR-ABL1 fusion gene mRNA encoding a 210 kDa tyrosine kinase which promotes leukemic transformation. A possible differential impact of the corresponding BCR-ABL1 transcript variants e13a2 ("b2a2") and e14a2 ("b3a2") on disease phenotype and outcome is still a subject of debate. A total of 1105 newly diagnosed imatinib-treated patients were analyzed according to transcript type at diagnosis (e13a2, n=451; e14a2, n=496; e13a2+e14a2, n=158). No differences regarding age, sex, or Euro risk score were observed. A significant difference was found between e13a2 and e14a2 when comparing white blood cells (88 vs. 65 × 10(9)/L, respectively; P<0.001) and platelets (296 vs. 430 × 10(9)/L, respectively; P<0.001) at diagnosis, indicating a distinct disease phenotype. No significant difference was observed regarding other hematologic features, including spleen size and hematologic adverse events, during imatinib-based therapies. Cumulative molecular response was inferior in e13a2 patients (P=0.002 for major molecular response; P<0.001 for MR4). No difference was observed with regard to cytogenetic response and overall survival. In conclusion, e13a2 and e14a2 chronic myeloid leukemia seem to represent distinct biological entities. However, clinical outcome under imatinib treatment was comparable and no risk prediction can be made according to e13a2 versus e14a2 BCR-ABL1 transcript type at diagnosis.

Deep molecular response is reached by the majority of patients treated with imatinib, predicts survival, and is achieved more quickly by optimized high-dose imatinib: results from the randomized CML-study IV

PURPOSE Deep molecular response (MR(4.5)) defines a subgroup of patients with chronic myeloid leukemia (CML) who may stay in unmaintained remission after treatment discontinuation. It is unclear how many patients achieve MR(4.5) under different treatment modalities and whether MR(4.5) predicts survival. PATIENTS AND METHODS Patients from the randomized CML-Study IV were analyzed for confirmed MR(4.5) which was defined as ≥ 4.5 log reduction of BCR-ABL on the international scale (IS) and determined by reverse transcriptase polymerase chain reaction in two consecutive analyses. Landmark analyses were performed to assess the impact of MR(4.5) on survival. RESULTS Of 1,551 randomly assigned patients, 1,524 were assessable. After a median observation time of 67.5 months, 5-year overall survival (OS) was 90%, 5-year progression-free-survival was 87.5%, and 8-year OS was 86%. The cumulative incidence of MR(4.5) after 9 years was 70% (median, 4.9 years); confirmed MR(4.5) was 54%. MR(4.5) was reached more quickly with optimized high-dose imatinib than with imatinib 400 mg/day (P = .016). Independent of treatment approach, confirmed MR(4.5) at 4 years predicted significantly higher survival probabilities than 0.1% to 1% IS, which corresponds to complete cytogenetic remission (8-year OS, 92% v 83%; P = .047). High-dose imatinib and early major molecular remission predicted MR(4.5). No patient with confirmed MR(4.5) has experienced progression. CONCLUSION MR(4.5) is a new molecular predictor of long-term outcome, is reached by a majority of patients treated with imatinib, and is achieved more quickly with optimized high-dose imatinib, which may provide an improved therapeutic basis for treatment discontinuation in CML.

Assessment of STR Typing Success Rate in Soft Tissues from Putrefied Bodies Based on a Quantitative Grading System for Putrefaction.

To date, there is no systematic investigation of the association of short tandem repeat (STR) typing success rate in soft tissues with different signs of putrefaction. Herein, putrefaction was rated using a newly developed 19-parameter system in soft tissues from a collective of 68 decaying bodies, and DNA yield was determined in 408 samples. DNA integrity was rated using a self-devised pentaplex PCR generating an "integrity score" (Si ). STR typing success rate was then assessed for selected cases. DNA yield and Si differed significantly between tissues with kidney on average exhibiting the highest Si values. Statistical analysis revealed that nine parameters were significantly and positively correlated with Si . The observed values for each of these nine parameters were summed up to generate a putrefaction score (Sp ) for each sample. Our results show that STR typing success rate can be predicted based on Sp before expensive multiplex STR profiling is performed.

Three essays on the concept of trust and its foundations

The present dissertation focuses on trust and comprises three empirical essays on the concept itself and its foundations. All three essays investigate trust as an expectation and rely on selfreport measures of trust. Whereas the first two chapters investigate social trust, the third chapter investigates political trust. Essentially, there are three related important debates to which the following chapters contribute. A first debate discusses problems with current selfreport measures. Scholars recently started to question whether standard trust questions really measure the same across countries and languages. Chapter 1 engages in this debate. Using data from Switzerland it studies whether different trust questions measure the same latent trust constructs across individuals belonging to three different culturallinguistic regions. The second debate concerns the socalled forms or dimensions of trust. Recently, scholars started investigating whether trust is a onedimensional construct, i.e. whether an individual's trust judgment differs for categories of trustees such as strangers, neighbors, family members and friends or not. Relying on confirmatory factor analysis Chapter 2 investigates whether individuals really do make a difference between different trustee categories and to what extent these judgments can be summarized into higherorder latent trust constructs. The third debate is concerned with causes of differences in trust across humans. Chapter 3 focuses on the role of laterlife experiences, more precisely victimization experiences and investigates their causal relationship with generalized social trust. Chapter 4 focuses on the impact of direct democratic institutions on the trust relationship between citizens and political authorities.

Simultaneous analysis of nuclear and mitochondrial DNA, mRNA and miRNA from backspatter from inside parts of firearms generated by shots at "triple contrast" doped ballistic models

When a firearm projectile hits a biological target a spray of biological material (e.g., blood and tissue fragments) can be propelled from the entrance wound back towards the firearm. This phenomenon has become known as "backspatter" and if caused by contact shots or shots from short distances traces of backspatter may reach, consolidate on, and be recovered from, the inside surfaces of the firearm. Thus, a comprehensive investigation of firearm-related crimes must not only comprise of wound ballistic assessment but also backspatter analysis, and may even take into account potential correlations between these emergences. The aim of the present study was to evaluate and expand the applicability of the "triple contrast" method by probing its compatibility with forensic analysis of nuclear and mitochondrial DNA and the simultaneous investigation of co-extracted mRNA and miRNA from backspatter collected from internal components of different types of firearms after experimental shootings. We demonstrate that "triple contrast" stained biological samples collected from the inside surfaces of firearms are amenable to forensic co-analysis of DNA and RNA and permit sequence analysis of the entire mtDNA displacement-loop, even for "low template" DNA amounts that preclude standard short tandem repeat DNA analysis. Our findings underscore the "triple contrast" method's usefulness as a research tool in experimental forensic ballistics.

Interpersonale Konsequenzen von offenen Selbstgesprächen in Dyaden im Sport

In der sportpsychologischen Forschung werden sowohl offene als auch verdeckte Selbstgespräche mehrheitlich als rein intrapersonale Phänomene betrachtet und sowohl deren Antezedenzien als auch Konsequenzen nur auf die mit sich selbst sprechende Person bezogen untersucht. Erste laborexperimentelle Studien, die die Effekte von offenen Selbstgesprächen auf die Eindrucksbildung (Graf, Lier & Seiler, 2012; Van Raalte, Brewer, Cornelius & Petitpas, 2006) und die individuelle Leistung (Gould & Weiss, 1981) eines Beobachters nachweisen konnten und Aussagen verschiedener Tennisspieler (Rimmer, Greenlees, Graydon, Thelwell & Buscombe, 2008), dass sie die offene Selbstgespräche der Gegner bei der Bildung eines ersten Eindrucks verwenden würden, deuten jedoch auf die Bedeutsamkeit von interpersonalen Konsequenzen von offenen Selbstgesprächen hin. Um das Verständnis für die interpersonalen Konsequenzen von offenen Selbstgesprächen im Sport zu vertiefen, wurden zwei Studien mit unterschiedlicher Methodik durchgeführt. In einer qualitativen Feldstudie wurden mit 13 Badmintonspielern im Anschluss an ihr Badminton Herren-Doppel Selbstkonfrontationsinterviews durchgeführt, um die Wahrnehmungsergebnisse nach offenen, während eines realen Wettkampfes geäusserten Selbstgesprächen zu untersuchen. Die wahrgenommenen positiven, negativen und motivierenden Selbstgespräche führten zu Zuschreibungen von mentalen Zuständen und Kognitionen und vereinzelt zur Einschätzung des episodischen Leistungsvermögens. Weiter lösten die Selbstgespräche verschiedene affektive Reaktionen und Erwartungsreaktionen aus, deren mögliche Konsequenzen für den weiteren Spielverlauf diskutiert werden. Um einzelne Resultate aus dieser ersten Studie eingehender zu analysieren (zugeschriebene Kompetenz und stellvertretende Valenzeinschätzung; Birrer & Seiler, 2008), und zur Untersuchung der Effekte der offenen Selbstgespräche auf die individuelle Leistung eines Teampartners wurde eine zweite, laborexperimentelle Studie durchgeführt. Zur Herstellung der drei experimentellen Bedingungen kam ein gleichgeschlechtlicher Konfident zum Einsatz, der als vermeintlicher Teampartner fungierte und der während der Golf-Putt-Aufgabe als Reaktion auf die eigenen Putts positive, negative oder keine Selbstgespräche führte. Bezogen auf die zugeschriebene Kompetenz zeigte sich kein allgemeiner, sondern ein von der Valenz der Probanden bedingter Effekt der negativen Selbstgespräche: War den Probanden die Aufgabe wichtig, führten negative Selbstgespräche zur Zuschreibung einer tiefen Kompetenz. Weiter lösten sowohl positive als auch negative Selbstgespräche die Einschätzung aus, dass dem Partner die Aufgabe wichtig ist. Keine Effekte hatten die Selbstgespräche auf die individuelle Leistung der Probanden. Explorativ durchgeführte Nachanalysen deuten jedoch darauf hin, dass sich die Selbstgespräche des Partners womöglich nach einer gewissen Zeit auf die individuelle Leistung der wahrnehmenden Person auswirken könnten, weshalb methodische Anpassungen diskutiert werden, mit Hilfe derer der Effekt der Selbstgespräche auf die Leistung gesteigert werden könnte. Neben den hypothesenprüfenden Tests ermittelten verschiedene Post-Hoc-Analysen aufschlussreiche Resulate (z.B. zu affektiven Reaktionen). Die Ergebnisse der beiden Studien bringen klar zum Ausdruck, dass die interpersonale Perspektive bei der Erforschung der Effekte von offenen Selbstgesprächen bedeutsame Erkenntnisse für Theorie und Praxis liefern kann.
