Methods: On three days in the week before the German Nationals, martial artists (N = 17) reported their competitive state anxiety and collected five samples of salivary cortisol during the first hour after awakening. Results: Hierarchic-linear models and multiple regressions were conducted. Despite a significant rise in "somatic anxiety" (p < .05), the increment of CAR across the week remained non-significant. A moderator function of competitive anxiety on the released amount of cortisol in the morning was not found significant. Results did not show any significant regression of changes in the neuroendocrine response on changes in state anxiety. Conclusion: Non- significant increments of CAR with a closer proximity to the competition may be interpreted as a possible habituation of basal hypothalamus-pituitary-adrenal activity. Moreover, athletes appear to have a lower CAR than found in norm studies, which points to further investigation of interindividual and situational effects on the temporal pattern of the neuroendocrine response to sport competitions.}, language = {en} } @article{InhoffSeymourSchadetal.2010, author = {Inhoff, Albrecht W. and Seymour, Bradley A. and Schad, Daniel and Greenberg, Seth}, title = {The size and direction of saccadic curvatures during reading}, issn = {0042-6989}, doi = {10.1016/j.visres.2010.03.025}, year = {2010}, abstract = {e movements during the reading of multi-line pages of texts were analyzed to determine the trajectory of reading saccades. The results of two experiments showed that the trajectory of the majority of forward-directed saccades was negatively biased, i.e., the trajectory fell below the start and end location of the saccadic movement. This is attributed to a global top-to-bottom orienting of attention. The curvature size and the proportion of negative trajectories were diminished when linguistic processing demands were high and when the beginning lines of a page were read. Longer pre-saccadic fixations also yielded smaller saccadic curvatures, and they resulted in fewer negatively curved forward-directed saccades in Experiment 1 although not in Experiment 2. These findings indicate that the top-to- bottom pull of saccadic trajectories is modulated by processing demands and processing opportunities. The results are in general agreement with a time-locked attraction-inhibition hypothesis, according to which the horizontal movement component of a saccade is initially subject to an automatic top-to-bottom orienting of attention that is subsequently inhibited.}, language = {en} } @article{HohensteinKliegl2010, author = {Hohenstein, Sven and Kliegl, Reinhold}, title = {Semantic preview benefit in eye movements during reading : a parafoveal fast-priming study}, issn = {0278-7393}, doi = {10.1037/A0020233}, year = {2010}, abstract = {Eye movements in reading are sensitive to foveal and parafoveal word features. Whereas the influence of orthographic or phonological parafoveal information on gaze control is undisputed, there has been no reliable evidence for early parafoveal extraction of semantic information in alphabetic script. Using a novel combination of the gaze- contingent fast-priming and boundary paradigms, we demonstrate semantic preview benefit when a semantically related parafoveal word was available during the initial 125 ms of a fixation on the pretarget word (Experiments 1 and 2). When the target location was made more salient, significant parafoveal semantic priming occurred only at 80 ms (Experiment 3). Finally, with short primes only (20, 40, 60 ms), effects were not significant but were numerically in the expected direction for 40 and 60 ms (Experiment 4). In all experiments, fixation durations on the target word increased with prime durations under all conditions. The evidence for extraction of semantic information from the parafoveal word favors an explanation in terms of parallel word processing in reading.}, language = {en} } @article{HerbertHerbertPollatosetal.2010, author = {Herbert, Beate M. and Herbert, Cornelia and Pollatos, Olga and Weimer, Katja and Sauer, Helene and Enck, Paul and Zipfel, Stephan}, title = {Effects of short-term food deprivation on interoceptive awareness, feelings and autonomic cardiac activity : implications for eating disorders}, issn = {0048-5772}, doi = {10.1111/j.1469-8986.2010.01111.x}, year = {2010}, abstract = {Poster session abstracts.

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

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} } @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{BuchmannKopfWestphaletal.2010, author = {Buchmann, Arlette F. and Kopf, Daniel and Westphal, Sabine and Lederbogen, Florian and Banaschewski, Tobias and Esser, G{\"u}nter and Schmidt, Martin H. and Zimmermann, Ulrich S. and Laucht, Manfred and Deuschle, Michael}, title = {Impact of early parental child-rearing behavior on young adults' cardiometabolic risk profile : a prospective study}, issn = {0033-3174}, doi = {10.1097/Psy.0b013e3181c88343}, year = {2010}, abstract = {Objective: To examine prospectively whether early parental child-rearing behavior is a predictor of cardiometabolic outcome in young adulthood when other potential risk factors are controlled. 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{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} }
