More specifically, a link between psychological factors and visceral hypersensitivity has been suggested, mainly based on research in functional gastrointestinal disorder patients. However, until recently, the exact nature of this putative relationship remained unclear, mainly due to a lack of non-invasive methods to study the （neurobiological） mechanisms underlying this relationship in non-sleeping humans. As functional brain imaging, introduced in visceral sensory neuroscience some 10 years ago, does provide a method for in vivo study of brain-gut interactions, insight into the neurobiological mechanisms underlying visceral sensation in general and the influence of psychological factors more particularly, has rapidly grown. In this article, an overview of brain imaging evidence on gastrointestinal sensation will be given, with special emphasis on the brain mechanisms underlying the interaction between affective ＆ cognitive processes and visceral sensation. First, the reciprocal neural pathways between the brain and the gut （brain- gut axis） will be briefly outlined, including brain imaging evidence in healthy volunteers. Second, functional brain imaging studies assessing the influence of psychological factors on brain processing of visceral sensation in healthy humans will be discussed in more detail. Finally, brain imaging work investigating differences in brain responses to visceral distension between healthy volunteers and functional gastrointestinal disorder patients will be highlighted.展开更多

By surveying 1,408 Chinese college students at five universities in China's Mainland, the results showed that among the factors examined, problem severity and help-seeking attitudes directly predicted help-seeking intention, while gender and subjective norms had a significant effect on college students＇ professional psychological help-seeking intention through help-seeking attitudes. Overall, the model explained 25% and 38.0% （for half-1 and half-2 data sets, respectively） of the variances of help-seeking intention. The results indicated that mainland Chinese college students rationally knew that they should choose to seek such professional help when the problem got severer enough, although they were emotionally reluctant to seek professional psychological help due to negative subjective norms around them. The implications and limitations were discussed.展开更多

The aim of this study is to analyze engagement in a group of 132 high school teachers from various schools in the private sector and identify its relationship with the commitment variable. The results of the work of this group in three dimensions are presented in this study： vigor, dedication, and absorption; the correlation data are also presented with organizational commitment in three dimensions： affective, normative and temporal （or continuity）. With these results the aim is to find predictive evidence among teachers who score significantly in the three dimensions of engagement and the three dimensions of commitment.展开更多
