We argue that heterophenomenology both over- and under-populates the intentional realm. For example, when one is involved in coping, one’s mind does not contain beliefs. Since the heterophenomenologist interprets all intentional commitment as belief, he necessarily overgenerates the belief contents of the mind. Since beliefs cannot capture the normative aspect of coping and perceiving, any method, such as heterophenomenology, that allows for only beliefs is guaranteed not only to overgenerate beliefs but also to undergenerate other kinds of intentional phenomena. 相似文献
Five mental components of human intentionality are distinguished and related to different properties of mammalian orientation. It is proposed that, in the course of evolution, these old properties became integrated and thereby allowed for the development of a new quality: human orientation. The existence of more than 4,000 mammal species with their various forms and levels of mental organization, offering a panorama of different combinations of differently developed components of mentality, provide ample opportunities for comparative studies. The difficulties in assessing specific types are outlined, drawing on over 40 years of observation. Based on this knowledge, an argument is made for the importance of staying in contact with the empirical objects and of considering their ontological status when rising the standards of precision of formal analysis. This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献
The vasopressin (VP)/oxytocin (OT)-related peptides constitute a large superfamily found in a wide range of both vertebrate and invertebrate species. While intensive literature reports that these neuropeptides influence behavior, especially learning and memory, in numerous species from diverse vertebrate groups, their roles in behavioral regulation have never been studied in invertebrates. Here, we investigated the role of two VP/OT superfamily peptides, octopressin (OP) and cephalotocin (CT), on long-term memory (LTM) formation of a passive avoidance task in a cephalopod mollusc, the cuttlefish, Sepia officinalis. Subadult cuttlefish were intravenously injected, in a dose range of 3–60 μg/kg, 1 h after the training phase (consolidation design); retention performance was tested 24 h post-training. We found that administration of OP at low dose (3 μg/kg) enhanced LTM, whereas a dose of 60 μg/kg attenuated it. No effect of OP on LTM was observed for the 15 μg/kg dose. Conversely, an enhancement of retention performance was observed at all doses of CT tested. This study is the first to demonstrate the behavioral effects of VP/OT superfamily peptides in an invertebrate species. The valuable role of VP/OT-like peptides on memory processes offers new evolutionary perspectives on peptidergic transmission and neuromodulation. 相似文献
Anyone interested in philosophical argumentation should be prepared to study philosophical debates and controversies because it is an intensely dialogical, and even contentious, genre of argumentation. There is hardly any other way to do them justice. This is the reason why the present special issue addresses philosophical argumentation within philosophical debates. Of the six articles in this special issue, one deals with a technical aspect, the diagramming of arguments, another contrasts two moments in philosophical argumentation, Antiquity and the twentieth century, focusing on the use of refutation, and the remaining four analyze particular philosophical controversies. The controversies analyzed differ significantly in their characteristics (time, extension, media, audience,…). Hopefully, this varied sample will illuminate some salient aspects of philosophical argumentation, its representation and variations throughout history. We are fully aware that, given the scarcity of previous studies of philosophical debates from the perspective of argumentation theory, the following specimens of analysis must have several shortcomings. But it is a well-known adage that the hardest part is the beginning. That is what we tried to achieve here, no more, but no less either.
In recent years, an increasing number of social and behavioral scientists have begun to pay serious attention to pluralistic ignorance, the shared false ideas of individuals about the sentiments, thoughts, and actions of others. Most of these researchers are unaware of the original effort to investigate these patterns of cognitive error and, consequently, misunderstand, as did the original investigators, some of the implications of their own work. The discovery of this important social phenomenon by Floyd H. Allport and his students, Daniel Katz and Richard L. Schanck, and how their preoccupation with individual characteristics and their relative neglect of social characteristics led them to underestimate the value of their discovery, is discussed. Allport's original interest in pluralistic ignorance and how he and Katz documented it empirically are presented, as is a review of Schanck's research extending their analysis. 相似文献
