These differences are influenced by environmental and genetic factors. Early childhood adversity is a well-studied environmental factor affecting an individual's stress response which has been shown to be modulated by gene environment interaction (GxE). Neuropeptide Y (NPY) plays a role in stress regulation and genetic variation in NPY may influence stress responses. In this study, we analyzed the association of a common variant in the NPY gene promoter, rs16147, with cortisol and ACTH responses to acute psychosocial stress in young adults from the Mannheim Study of Children at Risk (MARS), an ongoing epidemiological cohort study following the outcome of early adversity from birth into adulthood. We found evidence of a GxE interaction between rs16147 and early adversity significantly affecting HPA axis responses to acute psychosocial stress. These findings suggest that the neurobiological mechanisms linking early adverse experience and later neuroendocrine stress regulation are modulated by a gene variant whose functional relevance is documented by increasing convergent evidence from in vitro, animal and human studies.}, language = {en} } @unpublished{WarschburgerLehmkuhl2011, author = {Warschburger, Petra and Lehmkuhl, Ulrike}, title = {Disturbed eating behavior and its consequences}, series = {Praxis der Kinderpsychologie und Kinderpsychiatrie : Ergebnisse aus Psychotherapie, Beratung und Psychiatrie}, volume = {60}, journal = {Praxis der Kinderpsychologie und Kinderpsychiatrie : Ergebnisse aus Psychotherapie, Beratung und Psychiatrie}, number = {4}, publisher = {Vandenhoeck \& Ruprecht}, address = {G{\"o}ttingen}, issn = {0032-7034}, pages = {249 -- 252}, year = {2011}, language = {de} } @phdthesis{Vapenka2011, author = {V{\´a}penka, Aleš}, title = {Geschlechterstereotype und Geschlechtsidentit{\"a}t von M{\"a}nnern mit unterschiedlichem Verlauf der psychosexuellen Entwicklung}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-53175}, school = {Universit{\"a}t Potsdam}, year = {2011}, abstract = {Im Rahmen eines explorativen Vergleichsuntersuchungsplans wurde untersucht, inwieweit sich die durch biologische Faktoren bedingte unterschiedliche Lebenserfahrung sowie die Sozialisationsbedingungen in der psychosexuellen Entwicklung bei hetero-, homo- und postoperativen transsexuellen M{\"a}nnern (N = 191) auf die Integration der Geschlechterstereotypen in die kognitiven (Selbst-, Fremdwahrnehmung), emotionalen (Selbst- und Fremdbewertung) und verhaltensm{\"a}ßigen Aspekte (Normen der geschlechtsspezifischen Verhaltens) der Geschlechtsidentit{\"a}t auswirken und ob sich Identifikationsmuster der Entwicklung des geschlechtlichen Selbstkonzepts ableiten lassen. Die Messung der kognitiven Aspekte des geschlechtlichen Selbstkonzepts (Maskulinit{\"a}t und Femininit{\"a}t) erfolgte mittels der GERO-Skala von Brengelmann und Hendrich (1990). Zur Erfassung der emotionalen Aspekte und Identifikationsmuster der Entwicklung des geschlechtlichen Selbstkonzepts wurden die Werte f{\"u}r die Variablen Maskulinit{\"a}t und Femininit{\"a}t zuerst mittels der computergesteuerten Methodik IDEXMONO und IDEXIDIO, die auf der Identit{\"a}tsstrukturanalyse (Identity Structure Analysis) von Weinreich (2003) basiert, aufgearbeitet und weiter interferenzstatistisch ausgewertet. Weiterhin wurden der Fragebogen zur Messung normativer Geschlechtsrollenorientierung (NGRO) von Athenstaedt (2000) sowie ein ad hoc entworfener demographischer Fragebogen eingesetzt. Die Ergebnisse zeigen, dass der Verlauf der psychosexuellen Entwicklung einen starken Einfluss auf die Integration der Geschlechterstereotypen in die geschlechtliche Selbst- und Fremdwahrnehmung hat. Im kognitiven Bereich, bezogen auf die pers{\"o}nliche Identit{\"a}t (Grad der Selbstzuschreibung m{\"a}nnlicher und weiblicher Merkmale), stellt die Maskulinit{\"a}t eine stabile und erstrebenswerte Variable zur Herausbildung des geschlechtlichen Selbstkonzepts bei allen Gruppen dar. Die Femininit{\"a}t tr{\"a}gt am meisten zur Differenzierung zwischen den Hetero-, Homo- und Transsexuellen bei. Sie wird, je nach der Entwicklungsphase, unterschiedlich in das geschlechtliche Selbstkonzept integriert. Hinsichtlich der sozialen Identit{\"a}t (Zugeh{\"o}rigkeitsgef{\"u}hl) lassen sich die Gruppen bez{\"u}glich der wahrgenommenen {\"A}hnlichkeiten sowohl mit m{\"a}nnlichen als auch weiblichen Personen, je nach der Entwicklungsphase, unterscheiden. Die soziale Wahrnehmung von M{\"a}nnern und Frauen (Fremdwahrnehmung), ist bei Transsexuellen traditioneller als die der Hetero- und Homosexuellen. Bei der Selbst- und Fremdbewertung ergaben sich keine signifikanten Unterschiede. Bei der Internalisierung der sozialen Normen des geschlechtsspezifischen Verhaltens zeigt sich, dass Heterosexuelle der Aus{\"u}bung der Geschlechterrollen gegen{\"u}ber egalit{\"a}rer eingestellt sind als Trans- und Homosexuelle. Bei den Sozialisationsfaktoren ist hervorzuheben, dass generell weibliche Identifikationspersonen einen st{\"a}rkeren Einfluss auf die Herausbildung des geschlechtlichen Selbstkonzeptes hatten als m{\"a}nnliche Identifikationspersonen. Es scheint jedoch, dass Homosexuelle bei der Entwicklung ihres geschlechtlichen Selbstkonzepts st{\"a}rker unter dem Einfluss der Frauen stehen als die anderen zwei erforschten Gruppen. Zur Beantwortung der Frage, welche selbstkonzeptbezogenen Variablen und Entwicklungsfaktoren die gr{\"o}ßte statistische Bedeutung f{\"u}r die Trennung und Pr{\"a}diktion der einzelnen untersuchten Gruppen haben, wurde eine Diskriminanzanalyse berechnet. Die gr{\"o}ßte diskriminatorische Bedeutung besitzen die Variablen „Stereotypische Wahrnehmung der m{\"a}nnlichen Personen" und „Ego-Involvement mit weiblichen Personen" f{\"u}r die Diskriminanzfunktion 1 (Trennung der Transsexuellen von Hetero- und Homosexuellen) und die Variablen „Empathische Identifikation mit m{\"a}nnlichen Personen in der Vergangenheit" und „Zuwachs an empathischer Identifikation mit weiblichen Personen" f{\"u}r die Diskriminanzfunktion 2 (Trennung der Hetero- von Homosexuellen).}, language = {de} } @article{VoltmerSpahnSchaarschmidtetal.2011, author = {Voltmer, Edgar and Spahn, Claudia and Schaarschmidt, Uwe and Kieschke, Ulf}, title = {Work-related behavior and experience patterns of entrepreneurs compared to teachers and physicians}, series = {International archives of occupational and environmental health}, volume = {84}, journal = {International archives of occupational and environmental health}, number = {5}, publisher = {Springer}, address = {New York}, issn = {0340-0131}, doi = {10.1007/s00420-011-0632-9}, pages = {479 -- 490}, year = {2011}, abstract = {Purpose This study examined the status of health-related behavior and experience patterns of entrepreneurs in comparison with teachers and physicians to identify specific health risks and resources. Methods Entrepreneurs (n = 632), teachers (n = 5,196), and physicians (n = 549) were surveyed in a cross-sectional design. The questionnaire Work-related Behavior and Experience Patterns (AVEM) was used for all professions and, in addition, two scales (health prevention and self-confidence) from the Checklist for Entrepreneurs in the sample of entrepreneurs. Results The largest proportion of the entrepreneurs (45\%) presented with a healthy pattern (compared with 18.4\% teachers and 18.3\% physicians). Thirty-eight percent of entrepreneurs showed a risk pattern of overexertion and stress, followed by teachers (28.9\%) and physicians (20.6\%). Unambitious or burnout patterns were seen in only 9.3/8.2\% of entrepreneurs, respectively, and 25.3/27.3\% of teachers, and 39.6/21.5\% of physicians. While the distribution of patterns in teachers and physicians differed significantly between genders, a gender difference was not found among entrepreneurs. Entrepreneurs with the risk pattern of overexertion scored significantly (P < 0.01) lower in self-confidence and health care than those with the healthy pattern. Conclusions The development of a successful enterprise depends, in part, on the health of the entrepreneur. The large proportion of entrepreneurs with the healthy pattern irrespective of gender may support the notion that self-selection effects of healthy individuals in this special career might be important. At the same time, a large proportion was at risk for overexertion and might benefit from measures to cope with professional demands and stress and promote a healthy behavior pattern.}, language = {en} } @article{VockPreckelRolling2011, author = {Vock, Miriam and Preckel, Franzis and Rolling, Heinz}, title = {Mental abilities and school achievement a test of a mediation hypothesis}, series = {Intelligence}, volume = {39}, journal = {Intelligence}, number = {5}, publisher = {Elsevier}, address = {New York}, issn = {0160-2896}, doi = {10.1016/j.intell.2011.06.006}, pages = {357 -- 369}, year = {2011}, abstract = {This study analyzes the interplay of four cognitive abilities - reasoning, divergent thinking, mental speed, and short-term memory - and their impact on academic achievement in school in a sample of adolescents in grades seven to 10 (N = 1135). Based on information processing approaches to intelligence, we tested a mediation hypothesis, which states that the complex cognitive abilities of reasoning and divergent thinking mediate the influence of the basic cognitive abilities of mental speed and short-term memory on achievement. We administered a comprehensive test battery and analyzed the data through structural equation modeling while controlling for the cluster structure of the data. Our findings support the notion that mental speed and short-term memory, as ability factors reflecting basic cognitive processes, exert an indirect influence on academic achievement by affecting reasoning and divergent thinking (total indirect effects: beta=.22 and .24. respectively).

The anticipating and lag times depend on the difference between the feedback and the coupling delays. A single stability condition for all the different types of synchronization is found to be valid as the stability condition is independent of both the delays.

We report two experiments that aimed to study how real-time simulation is affected by simultaneous action execution under conditions of full, partial or no overlap between observed and executed actions. This overlap was analysed by comparing the body sides and the movement kinematics involved in the observed and the executed action. While performing actions, participants observed point-light (PL) actions that were interrupted by an occluder, followed by a test pose. The task was to judge whether the test pose depicted a continuation of the occluded action in the same depth angle. Using a paradigm proposed by Graf et al., we independently manipulated the duration of the occluder and the temporal advance of the test pose relative to occlusion onset (occluder time and pose time, respectively). This paradigm allows the assessment of real-time simulation, based on prediction performance across different occluder time/pose time combinations (i.e., improved task performance with decreasing time distance between occluder time and pose time is taken to reflect real-time simulation). The PL actor could be perceived as from the front or back, as indicated by task instructions. In Experiment 1 (front view instructions), evidence of action simulation was obtained for partial overlap (i.e., observed and performed action corresponded either in body side or movement kinematics), but not for full or no overlap conditions. The same pattern was obtained in Experiment 2 (back view instructions), ruling out a spatial compatibility explanation for the real-time pattern observed. Our results suggest that motor processes affect action prediction and real-time simulation. The strength of their impact varies as a function of the overlap between observed and executed actions.}, language = {en} }
