In a prospective longitudinal study of children at risk for later psychopathology, 300 participants were assessed for regulatory problems in infancy, DRD4 genotype, and ADHD symptoms and diagnoses from childhood to adolescence. To examine a potential moderating effect on ADHD measures, linear and logistic regressions were computed. Models were fit for the main effects of the DRD4 genotype (presence or absence of the 7r allele) and regulatory problems (presence or absence), with the addition of the interaction term. All models were controlled for sex, family adversity, and obstetric risk status. In children without the DRD4-7r allele, a history of regulatory problems in infancy was unrelated to later ADHD. But in children with regulatory problems in infancy, the additional presence of the DRD4-7r allele increased the risk for ADHD in childhood. The DRD4 genotype seems to moderate the association between regulatory problems in infancy and later ADHD. A replication study is needed before further conclusions can be drawn, however.}, language = {en} } @article{BelschakDenHartogFay2010, author = {Belschak, Frank D. and Den Hartog, Deanne N. and Fay, Doris}, title = {Exploring positive, negative and context-dependent aspects of proactive behaviours at work}, issn = {0963-1798}, doi = {10.1348/096317910x501143}, year = {2010}, abstract = {This article is an introduction to the Special Section entitled 'Exploring positive, negative and context- dependent aspects of proactive behaviours at work' which features in this issue of Journal of Occupational and Organizational Psychology.}, language = {en} } @phdthesis{Berger2010, author = {Berger, Anja}, title = {Entwicklung und Validierung eines Inventars zur Erfassung positiver und negativer Attribute des Geschlechtsrollenselbstkonzepts}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-51215}, school = {Universit{\"a}t Potsdam}, year = {2010}, abstract = {Das Geschlechtsrollenselbstkonzept, das sich im Laufe der Sozialisation in Auseinandersetzung mit den vorherrschenden Vorstellungen der umgebenden Kultur entwickelt, steht in Beziehung zu Affekten, Kognitionen und Verhaltensweisen in einer Vielzahl von Bereichen. Bisherige GSK-Instrumente messen jedoch nahezu ausschließlich den positiven Aspekt von Maskulinit{\"a}t und Femininit{\"a}t. Die Definition des allgemeinen Selbstkonzepts gibt diese Limitierung auf positive Valenz nicht vor, und aus gesundheitspsychologischer Sicht sowie der Gruppenforschung ist die Bedeutung negativer Eigenschaften zur Selbstbeschreibung bekannt. Vor diesem Hintergrund wurden sieben aufeinander aufbauende Studien durchgef{\"u}hrt mit dem Ziel ein neues Instrument zu entwickeln, deren Items zum einen kulturell aktuellen Eigenschaften zur Selbstbeschreibung entsprechen und zum anderen die Valenzunterschiede dieser Merkmalsbeschreibungen ber{\"u}cksichtigen. Nach einer kritischen empirischen {\"U}berpr{\"u}fung des deutschen BSRI, um Schw{\"a}chen der Items ausschließlich positiver Valenz aufzudecken, wurde eine neue Skala entwickelt, die von Beginn an auch negative Selbstbeschreibungen ber{\"u}cksichtigte um der Komplexit{\"a}t des geschlechtlichen Selbst gerecht zu werden. Aufgrund der Einsch{\"a}tzungen zur Typizit{\"a}t und sozialen Erw{\"u}nschtheit sowie mit ersten Resultaten aus der Selbstbeschreibung wurde die Auswahl der Items f{\"u}r die Teilskalen vorgenommen. In zwei weiteren Studien wurden schließlich die vier neu entwickelten Teilskalen des neuen GSK-Inventars einer Validierung unterzogen. Jeder der Teilskalen wurden theoriegeleitet spezifische Konstrukte zugeordnet und es konnte nachgewiesen werden, dass alle Teilskalen ihren eigenen Beitrag zur Vorhersage psychologischer Konzepte leisten k{\"o}nnen. So standen beispielsweise die negativen maskulinen Eigenschaften in engerer Beziehung zu Aggressivit{\"a}t und machtbezogenen Werten als die positiven Aspekte der Maskulinit{\"a}t. Als Ergebnis dieser Entwicklung stehen am Ende vier kurze, unabh{\"a}ngige, reliable Teilskalen, die positive als auch negative Aspekte von Maskulinit{\"a}t und Femininit{\"a}t abbilden und mittels sehr unterschiedlicher psychologischer Erlebens- und Verhaltenskonstrukte validiert wurden, die die Unabh{\"a}ngigkeit der Skalen belegen und diese f{\"u}r einen Einsatz in der Forschung empfehlen.

Metabolic factors associated with increased risk for cardiovascular disease have been found to vary, depending on lifestyle as well as genetic predisposition. Moreover, there is evidence suggesting that environmental conditions, such as stress in pre- and postnatal life, may have a sustained impact on an individual's metabolic risk profile. Methods: Participants were drawn from a prospective, epidemiological, cohort study followed up from birth into young adulthood. Parent interviews and behavioral observations at the age of 3 months were conducted to assess child-rearing practices and mother-infant interaction in the home setting and in the laboratory. In 279 participants, anthropometric characteristics, low-density lipoprotein and high-density lipoprotein cholesterol, apolipoproteins, and triglycerides were recorded at age 19 years. In addition, structured interviews were administered to the young adults to assess indicators of current lifestyle and education. Results: Adverse early-life interaction experiences were significantly associated with lower levels of high- density lipoprotein cholesterol and apolipoprotein A1 in young adulthood. Current lifestyle variables and level of education did not account for this effect, although habitual smoking and alcohol consumption also contributed significantly to cardiometabolic outcomes. Conclusions: These findings suggest that early parental child-rearing behavior may predict health outcome in later life through its impact on metabolic parameters in adulthood.}, language = {en} } @article{BuchmannLauchtSchmidetal.2010, author = {Buchmann, Arlette F. and Laucht, Manfred and Schmid, Brigitte and Wiedemann, Klaus and Mann, Karl F. and Zimmermann, Ulrich S.}, title = {Cigarette craving increases after a psychosocial stress test and is related to cortisol stress response but not to dependence scores in daily smokers}, issn = {0269-8811}, doi = {10.1177/0269881108095716}, year = {2010}, abstract = {Stress is known to induce cigarette craving in smokers, but the underlying mechanisms are widely unknown. We investigated how dependence severity, smoking habits and stress-induced cortisol secretion are associated with increased cigarette craving after a standardised laboratory stressor. Hundred and six healthy participants (50 men, age 18-19 years) underwent a standardised public speaking stress task. In all, 35 smoked daily (DS), 13 smoked occasionally (OS), and 58 never smoked (NS). Smoking was unrestricted until 2 h before stress onset. Plasma cortisol was measured before and up to 95 min after the stressor. All current smokers rated intensity of cigarette craving immediately before and immediately after the stressor using the Brief Questionnaire of Smoking Urges (BQSU). Cortisol levels significantly increased in response to stress in all groups. The magnitude of this stress response was significantly lower in DS compared with OS and NS but did not differ between OS and NS. Baseline BQSU scores were significantly higher in DS than OS. BQSU scores increased significantly during the stress period and were positively correlated to the cortisol response in the DS but were unrelated to their nicotine dependence scores. In OS, no change in cigarette craving could be observed. In daily smokers, cigarette craving is increased after compared with before stress exposure and is related to the magnitude of cortisol stress response rather than to severity of nicotine dependence. This result supports, but does not prove, the concept that hypothalamus-pituitary-adrenal stimulation is one of the mechanisms how stress can elicit cigarette craving.}, language = {en} } @article{BuchmannSchmidBlomeyeretal.2010, author = {Buchmann, Arlette F. and Schmid, Brigitte and Blomeyer, Dorothea and Zimmermann, Ulrich S. and Jennen-Steinmetz, Christine and Schmidt, Martin H. and Esser, G{\"u}nter and Banaschewski, Tobias and Mann, Karl F. and Laucht, Manfred}, title = {Drinking against unpleasant emotions : possible outcome of early onset of alcohol use?}, issn = {0145-6008}, doi = {10.1111/j.1530-0277.2010.01180.x}, year = {2010}, abstract = {Background: Recent animal and human studies indicate that the exposure to alcohol during early adolescence increases the risk for heavy alcohol use in response to stress. The purpose of this study was to examine whether this effect may be the consequence of a higher susceptibility to develop "drinking to cope" motives among early initiators. Methods: Data from 320 participants were collected as part of the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study. Structured interviews at age 15 and 19 were used to assess age at first alcohol experience and drunkenness. The young adults completed questionnaires to obtain information about the occurrence of stressful life events during the past 4 years and current drinking habits. In addition, alcohol use under conditions of negative states was assessed with the Inventory of Drinking Situations. Results: The probability of young adults' alcohol use in situations characterized by unpleasant emotions was significantly increased the earlier they had initiated the use of alcohol, even when controlling for current drinking habits and stressful life events. Similar results were obtained for the age at first drunkenness. Conclusions: The findings strengthen the hypothesis that alcohol experiences during early adolescence facilitate drinking to regulate negative affect as an adverse coping strategy which may represent the starting point of a vicious circle comprising drinking to relieve stress and increased stress as a consequence of drinking.}, language = {en} } @misc{DaigMahlbergSchroederetal.2010, author = {Daig, Isolde and Mahlberg, Richard and Schroeder, Franziska and Gudlowski, Yehonala and Wrase, Jana and Wertenauer, Florian and Bschor, Tom and Esser, G{\"u}nter and Heinz, Andreas and Kienast, Thorsten}, title = {Low effective organizational strategies in visual memory performance of unmedicated alcoholics during early abstinence}, issn = {1860 - 5214}, year = {2010}, language = {en} } @book{Dambacher2010, author = {Dambacher, Michael}, title = {Bottom-up and top-down processes in reading : influences of frequency and predictability on event-related potentials and eye movements}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-059-5}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-42024}, publisher = {Universit{\"a}t Potsdam}, pages = {239}, year = {2010}, abstract = {In reading, word frequency is commonly regarded as the major bottom-up determinant for the speed of lexical access. Moreover, language processing depends on top-down information, such as the predictability of a word from a previous context. Yet, however, the exact role of top-down predictions in visual word recognition is poorly understood: They may rapidly affect lexical processes, or alternatively, influence only late post-lexical stages. To add evidence about the nature of top-down processes and their relation to bottom-up information in the timeline of word recognition, we examined influences of frequency and predictability on event-related potentials (ERPs) in several sentence reading studies. The results were related to eye movements from natural reading as well as to models of word recognition. As a first and major finding, interactions of frequency and predictability on ERP amplitudes consistently revealed top-down influences on lexical levels of word processing (Chapters 2 and 4). Second, frequency and predictability mediated relations between N400 amplitudes and fixation durations, pointing to their sensitivity to a common stage of word recognition; further, larger N400 amplitudes entailed longer fixation durations on the next word, a result providing evidence for ongoing processing beyond a fixation (Chapter 3). Third, influences of presentation rate on ERP frequency and predictability effects demonstrated that the time available for word processing critically co-determines the course of bottom-up and top-down influences (Chapter 4). Fourth, at a near-normal reading speed, an early predictability effect suggested the rapid comparison of top-down hypotheses with the actual visual input (Chapter 5). The present results are compatible with interactive models of word recognition assuming that early lexical processes depend on the concerted impact of bottom-up and top-down information. We offered a framework that reconciles the findings on a timeline of word recognition taking into account influences of frequency, predictability, and presentation rate (Chapter 4).}, language = {en} } @misc{DeimannKastnerKollerEsseretal.2010, author = {Deimann, Pia and Kastner-Koller, Ursula and Esser, G{\"u}nter and H{\"a}nsch, Sylvana}, title = {FRAKIS Fragebogen zur fr{\"u}hkindlichen Sprachentwicklung : FRAKIS (Standardform) und FRAKIS-K (Kurzform)}, year = {2010}, language = {de} } @article{EngbertKruegel2010, author = {Engbert, Ralf and Kruegel, Andr{\´e}}, title = {Readers use Bayesian estimation for eye movement control}, issn = {0956-7976}, doi = {10.1177/0956797610362060}, year = {2010}, abstract = {During reading, saccadic landing positions within words show a pronounced peak close to the word center, with an additional systematic error that is modulated by the distance from the launch site and the length of the target word.

We present the first mathematical model for the saccadic range error; this model makes explicit assumptions regarding underlying visual and oculomotor processes.
