OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis. 相似文献

College-level biology courses contain many complex processes that are often taught and learned as detailed narratives. These processes can be better understood by perceiving them as dynamic systems that are governed by common fundamental principles. Conservation of matter is such a principle, and thus tracing matter is an essential step in learning to reason about biological processes. We present here multiple-choice questions that measure students' ability and inclination to trace matter through photosynthesis and cellular respiration. Data associated with each question come from students in a large undergraduate biology course that was undergoing a shift in instructional strategy toward making fundamental principles (such as tracing matter) a central theme. We also present findings from interviews with students in the course. Our data indicate that 1) many students are not using tracing matter as a tool to reason about biological processes, 2) students have particular difficulties tracing matter between systems and have a persistent tendency to interconvert matter and energy, and 3) instructional changes seem to be effective in promoting application of the tracing matter principle. Using these items as diagnostic tools allows instructors to be proactive in addressing students' misconceptions and ineffective reasoning. 相似文献

At the turn of the 21st century a methodological analysis of the planetary development of civilization became a topical issue in world science. Such an analysis is based on a framework of categorical concepts adopted for active use in globalistics, namely, the biosphere, sociosphere, technosphere, noosphere, and infosphere. The given context provides a new perspective on the phenomenon of information and informatics, with the latter having experienced increasing demands as a popular scientific discipline in the field of information. In the contemporary setting, these phenomena can be adequately evaluated only in connection with the above concepts. 相似文献

We use prices realized for Picasso prints at auctions worldwide, as well as the 100 prints that comprise his Vollard Suite,
to test the law of one price: the proposition that identical art objects sold contemporaneously should command the same price
regardless of the auction house or geographic region where the sale takes place. Picasso is the most prolific printmaker of
the twentieth century and, from 1977 to 2004, his prints appreciated in price significantly faster than the prints of modern
masters as a whole. We find that Picasso prints sold in the United States command higher prices than in Europe. However, prices
realized at Sotheby’s in New York are no longer higher than at Christie’s in New York, nor at Kornfeld than at other auction houses. We find evidence of “irrational exuberance”
in the transitory nature of the extraordinary prices realized for the Picasso prints included in the 1997 sale of the collection
of Victor and Sally Ganz at Christie’s in New York. More generally, we find substantial noise in auction outcomes, a result
well known to savvy auction goers.
