The mammalian hippocampus is certainly one of the best investigated brain regions. It fascinates neuroscientists particularly because of its important role in memory. The names for the various parts of the hippocampal formation were created in the course of the first thorough explorations of human brain anatomy. The present, internationally agreed terminology reflects an unfortunate muddle that has been going on for several hundred years. Not surprisingly, even today the origins of some of the names are not always given correctly. It is generally accepted that the Italian anatomist Arantius was the first to apply the term 'hippocampus' to part of that region in the human brain. To later authors, however, this name appeared more or less enigmatic and they proposed various other terms. Yet careful reading of the entire original text of Arantius leads to the conclusion that it was not the hippocampus in our modern terms but the dentate gyrus which he compared to a little sea horse or a silkworm.  相似文献

正The symptoms of anxiety and depression are highly overlapping with each other and are hard to differentiate in clinical settings.Researchers have attempted to develop measures specifically capturing and differentiating symptoms of these two constructs.The Depression Anxiety Stress Scale(DASS)was developed to meet this challenge and has been shown to capture depression,anxiety,and stress  相似文献

The domain of transition studies has been drawing more and more scholarly attention and, as a result, its body of knowledge is rapidly growing. This raises new challenges as well as opportunities, not the least regarding the methodological and philosophical underpinnings of research in this domain. In this respect, transition research, as a relatively young field of inquiry, has been little concerned with methodological investigation and reflection. We propose a framework that enables this reflection: the so-called ‘transition research onion’. Subsequently, we utilize this framework to systematically assess 217 peer-reviewed papers in the field of transition studies, to distill key methodological patterns and trends of the field. The findings suggest that the methodology of transition studies, in terms of depth and diversity, is underdeveloped. These insights serve to guide future research on transition processes.  相似文献

For many, the very idea of an artificialintelligence has always been ethicallytroublesome. The putative ability of machinesto mimic human intelligence appears to callinto question the stability of taken forgranted boundaries between subject/object,identity/similarity, free will/determinism,reality/simulation, etc. The artificiallyintelligent object thus appears to threaten thehuman subject with displacement and redundancy.This article takes as its starting point AlanTuring's famous 'imitation game,' (the socalled 'Turing Test'), here treated as aparable of the encounter between human originaland machine copy – the born and the made. Thecultural resonances of the recent on-lineperformance of a 'Turing Test' for computergenerated art are then explored. Arttraditionally taken to stand for all that isconsidered quintessentially human – andtherefore resistant to mechanisation –represents in this sense a kind of 'criticalcase' in the advance of machine intelligence.The article focuses on the moral status of thebody, human agency, and social knowledge in theongoing (re-)constructions of copy, original,and of the difference between them.  相似文献

This paper presents a model of the determinants and consequences of computer efficacy with particular attention devoted to the mediating processes through which users form efficacy judgements, including their analysis of task requirements, assessments of situational and personal resources/constraints, and attributional analysis of experience. Of particular interest to this paper are the attributional processes affecting computer efficacy. Recommendations for computer and attributional training are advanced.  相似文献
