The present research examined the interplay of individual differences in self‐regulatory mechanisms as outlined in regulatory focus theory (promotion‐ and prevention‐focus) and a cue of being watched in the context of cooperative behaviour. Study 1 revealed that the more individuals' habitual self‐regulatory orientation is dominated by a vigilant prevention focus, the more likely they are to act cooperatively (i.e. to donate money to natural conservation organizations) when a subtle cue of being watched renders reputational concerns salient. In contrast, when no such cue is provided individuals' habitual vigilant self‐regulatory orientation is negatively related to cooperative behaviour. Study 2 replicated the results of the initial study and examined interpersonal sensitivity (empathic concern) as a potential mediator of the observed effects.

Cortisol affects the acute-phase response, but it is unknown whether C-reactive protein (CRP), an acute-phase reactant, also affects hypothalamus?pituitary?adrenal axis activity. In the present study, associations were explored between CRP haplotypes with plasma CRP concentrations and basal salivary cortisol level. We included 266 physically healthy Caucasian subjects (103 females and 163 males) aged between 18 and 65 years of whom 94 had a psychiatric disorder in a genetic association study. Six tag single-nucleotide polymorphisms capturing the common genetic variation of the CRP gene were genotyped (i.e. rs2808628, rs2808630, rs1205, rs1800947, rs1417938, and rs3091244) to yield common CRP haplotypes. Plasma CRP concentrations, the salivary cortisol awakening response (CAR) (0, 30, 45, and 60?min after awakening), and the diurnal cortisol decline (11:00, 15:00, 19:00, and 23:00 h) were assessed for 2 days. rs2808628, rs1205, rs1417938, and rs3091244 showed expected associations not only with CRP concentrations, but also with salivary cortisol levels during the CAR. Five well-characterized CRP haplotypes were arranged in ascending order according to increasing CRP levels. There was an inverse linear association between CRP haplotypes and cortisol levels during the CAR, but no association with the diurnal cortisol decline. Hence, genetic variants in the CRP gene that are associated with lifetime plasma CRP levels were also associated with salivary cortisol levels after awakening, in basal, non-inflammatory conditions. 相似文献

Although animal researchers established the role of testosterone as a 'social hormone' decades ago, the investigation of its causal influence on human social behaviors has only recently begun. Here, we review and discuss recent studies showing the causal effects of testosterone on social interactions in animals and humans, and outline the basic neurobiological mechanisms that might underlie these effects. Based on these recent findings, we argue that the role of testosterone in human social behavior might be best understood in terms of the search for, and maintenance of, social status. 相似文献

The mechanisms for the substantial variation in the durations of visual fixations in scene perception are not yet well understood. During free viewing of paintings, gaze-contingent irrelevant distractors (Exp. 1) and non-gaze-related time-locked display changes (Exp. 2) were presented. We demonstrated that any visual change-its onset and offset-prolongs the ongoing fixation (i.e., delays the following saccade), strongly suggesting that fixation durations are under the direct control of the stimulus information. The strongest influence of distraction was observed for fixations preceded by saccades within the parafoveal range (<5° of visual angle). We assume that these fixations contribute to the focal in contrast to the ambient mode of attention (Pannasch & Velichkovsky, Visual Cognition, 17, 1109-1131, 2009; Velichkovsky, Memory, 10, 405-419, 2002). Recent findings about two distinct "subpopulations of fixations," one under the direct and another under the indirect control of stimulation (e.g., Henderson & Smith, Visual Cognition, 17, 1055-1082, 2009), are reconsidered in view of these results. 相似文献

The present study examines whether disengagement from previous work‐roles positively predicts adaptation to a new work‐role (here, becoming self‐employed) by reducing negative consequences of psychological attachment to these previous roles. Disengagement involves an individual's effort to release attention from thoughts and behaviours related to the previous work‐role. A three‐wave longitudinal study investigated the relationship between psychological attachment (measured as affective commitment) to a prior work‐role, disengagement from the prior work‐role, and adaptation to a new work‐role [pursuit of learning, fit perceptions with self‐employment, task performance over time]. Participants included 131 persons who recently founded a small business. Results indicated that psychological attachment to the past work‐role was negatively related to pursuit of learning and fit with the new work‐role. Disengagement from the past work‐role was positively related to pursuit of learning in the new work‐role, and buffered the negative relationship between psychological attachment and fit as well as task performance. 相似文献

Several software programs exist to assist researchers in setting up online questionnaires. Existing tools are of little help
for delivering online rating studies, for which it is often desirable to collect data from participants for only a subset
of a stimulus set. OR-Vis enables researchers to quickly set up online rating studies by supplying the set of items to be
rated, the number of stimuli an individual participant responds to, the number of participants an item is shown to, and the
rating questions. The software then generates and delivers unique questionnaires for each participant, while managing the
data collection process. The present article describes OR-Vis, its installation process, and how to use it to gather data.
OR-Vis is open-source software and can be downloaded from www.orvis.uni-muenster.de. 相似文献

Since 2006, the development of the jurisdiction concerning the subsequent preventive detention has kept the continuity of the first decisions by the German Federal Supreme Court. An imprisonment according to the new law standards was decreed only in a few cases. The legislator’s attempts to enlarge its use by introduction of § 66b I 2 German penal code in substance were ineffective, because both the German Federal Supreme Court and the Federal Constitutional Court has viewed the law as constitutional, only, if its use is limited to a few “extreme cases”. Further difficulties appeared by the injunction of the subsequent preventive detention due to an acquittal statement of a hospital order treatment. At this some questions still remain unanswered. 相似文献

Sunscreens with Titanium Dioxide (TiO<Subscript>2</Subscript>) Nano-Particles: A Societal Experiment
The risks of novel technologies, such as nano(bio)technology cannot be fully assessed due to the existing uncertainties surrounding
their introduction into society. Consequently, the introduction of innovative technologies can be conceptualised as a societal
experiment, which is a helpful approach to evaluate moral acceptability. This approach is illustrated with the marketing of
sunscreens containing nano-sized titanium dioxide (TiO2) particles. We argue that the marketing of this TiO2 nanomaterial in UV protective cosmetics is ethically undesirable, since it violates four reasonable moral conditions for
societal experimentation (absence of alternatives, controllability, limited informed consent, and continuing evaluation).
To remedy the current way nano-sized TiO2 containing sunscreens are utilised, we suggest five complementing actions (closing the gap, setup monitoring tools, continuing
review, designing for safety, and regulative improvements) so that its marketing can become more acceptable. 相似文献

The Clock Drawing Test (CDT) is a widely used instrument in the neuropsychological assessment of Alzheimer's disease (AD). As CDT performance necessitates several cognitive functions (e.g., visuospatial and constructional abilities, executive functioning), an interaction of multiple brain regions is likely. Fifty-one subjects with mild cognitive impairment, 23 with AD and 15 healthy controls underwent high-resolution magnetic resonance imaging. Optimized voxel-based morphometry (VBM) was performed to investigate the putative association between CDT performance and gray matter (GM) density throughout the entire brain. In the first step of analysis (p<.001, uncorrected), VBM revealed a reduced GM density in numerous cortical (temporal lobe, frontal lobe, parietal lobe, cerebellum) and subcortical (thalamus, basal ganglia) brain regions to be associated with poorer CDT performance. When corrected for multiple comparisons (p<.01), the associations remained significant predominantly in the left temporal and--less pronounced--the right temporal lobe. VBM demonstrated CDT performance to depend on the integrity of widely distributed cortical and subcortical areas in both brain hemispheres with accentuation in the left-sided temporal lobe region. 相似文献
