A reading time and an ERP experiment conducted in Italian investigated the parser's responses to a syntactic violation (subject-verb number agreement) and to a semantic violation (subject-verb selectional restriction), examining the time course of comprehension processes until sentence end. The reading-time data showed that the syntactic violation was detected earlier than the semantic one and that the two violations differed in the time-course. The ERP data fully supported the reading time data: Syntactic anomalies elicited a left anterior negativity (LAN) and a P600. Semantic anomalies elicited a N400 centred on the parietal sites which started 90 ms later (latency 430 ms) than the LAN. Furthermore, the N400 evoked by the words that followed the target word continued and increased until sentence end. The results are discussed with respect to the hypotheses that the parser constructs distinct syntactic and semantic analyses of a sentence and that this characteristic holds cross-linguistically. The appropriateness of different methodologies to the study of sentence processing is also evaluated. 相似文献
Four experiments were conducted in order to study the segmentation process in a visual search task with relevant stimuli (target and distractors) randomly distributed among textural elements. The basic idea was that a parallel segmentation process of the relevant stimuli would contribute to the overall reaction time independently of the contribution of the number of relevant stimuli. In the first experiment, with relevant stimuli and textural elements that differed in the orientation of their component lines, texture presence interacted with number of relevant stimuli and with target presence. These results were not favorable to the parallel segmentation hypothesis. In the second and third experiments, in which the relevant and the textural stimuli differed in orientation and in the luminance contrast of their component lines, the results support a parallel segmentation process for the higher contrast conditions. In these experiments, the effect of texture presence was greater on target-absent than on target-present trials. Experiment 4 shows that the search can be restricted to the high-contrast relevant stimuli when the number of these stimuli is constant and the number of textural stimuli changes from trial to trial. The present results suggest that the relevant stimuli can be segmented in parallel and then submitted to a restricted analysis, even when they are scattered among textural stimuli. 相似文献
This installment of Dialog's Theology in Film and Fiction series introduces the first Cape Verdean novel, The Slave, by José Evaristo d'Almeida (1856). This vivid story depicts a number of social and moral issues tied together within the tragic plot of the novel. The article discusses the historical relationship of the Roman Catholic Church to slavery, the colonial history of Portugal and Cape Verde, and the theological use of the Bible in this history. This discussion is applied to Almeida's novel, revealing the manifold nineteenth‐century varieties of the literary history and theology of colonialism. 相似文献
It is widely assumed that the art media can be individuated with reference to the sense modalities. Different art media are perceived by means of different sense modalities, and this tells us what properties of each medium are aesthetically relevant. The case of pictures appears to fit this principle well, for pictures are deemed purely and paradigmatically visual representations. However, recent psychological studies show that congenitally and early blind people have the ability to interpret and make raised-line drawings through touch. This shows that pictures are not essentially visual representations. The view that pictures are essentially visual follows from influential views of the nature of depiction and of the nature of vision that are mistaken. By rooting out the mistake, we learn something about pictures, something about vision, and something about the doctrine that art media are individuated by the sense modalities. 相似文献
According to the tradition of natural law justice is inherent to, and should always be observed in, all interpersonal relations: the science of natural law is nothing more or less than the expression of such principles of justice. The theoretical peculiarities that crop up regarding the lawfulness of appropriation are determined by the indirect interpersonal relations that take place within the process of appropriation: though appropriation is an action directed not towards another person or his property, but towards tangible external goods, this action may have important consequences for other people. Therefore Locke's theory of appropriation is a theory of justice.Locke's solution is made possible by the methodological improvement which allows a clear separation between the natural law and the historical and empirical conditions of its application: this improvement is a consequence of the distinction between modes and substances established in Locke's Essay.Locke's theory can be considered an extensive re-elaboration, in polemic against Filmer, of the anti-monopolistic principle characteristic of the whole of Scholastic social thought: this principle is intimately connected with the principle of man's natural liberty.Locke maintains a negative and formal conception of justice: justice prohibits interference with others' liberty of appropriation. Alongside the justice is the positive and conditional obligation of charity which prescribes the transfer of some of one's own goods to others who need them in order to survive. But for Locke there are precise limits on the obligation of charity: the application of charity suspends the application of justice only when the immediate physical survival is at stake; in all other cases justice leaves no room for charity.The Lockian negative conception of justice, which allows unlimited liberty of appropriation, is dependent on the empirical and historical condition of the incommensurability of the main resource. The widespread use of money acts as an accelerating element in the process of exhaustion of the incommensurability of land-resources but, at the same time, it renders self-preservation and appropriation almost completely independent of the natural environment. Money creates an infinite number of opportunities for the outlay of labour irrespective of the availability of land, that is, it renders labour the principal resource of the civilized world, and labour is an incommensurable and infinitely reproducible resource. The incommensurability of the labour resource thus supports the Lockian theory of negative distributive justice; but over the Lockian solution already loomed the threatening shadow of pauperism.The subject of this essay is further dealt with in my book on Locke's political and social philosophy Nel crepuscolo della probabilitá, Bibliopolis, Napoli, 1983. There I develop further the interpretation of Locke's theory of justice presented here and analyse his theoretical and historical presuppositions. 相似文献
The paper compares the tree-theoretical model of similarity judgement (in which the similarity between two objects is a function of the distance between them in a conceptual tree) with an averaging model of similarity judgement that is drawn jointly from information integration theory and from current research indicating the prevalence of anchoring and adjustment mechanisms in judgement. Results of an experiment are presented that suggest that even when subjects organize conceptual material as a hierarchical tree, judgments of similarity among the objects are better accounted for by an averaging mechanism than by distances in the tree. These data are discussed in terms of the differences between the representation in which knowledge is encoded and the processes that operate on the represented information. 相似文献
A comparison involving cumulative probability distributions of reaction time (RT) has been used to test race models of the redundancy gain observed in certain divided-attention paradigms. It has beenpointed out, however, that the presence of fast guesses wouldinterfera with this test, biasing it to accept race models. The present paper reports simulations carried out to determine the size of the bias introduced by fast guesses. In absolute terms, this bias can be quite large— exceeding 175 msec in some conditions. Simulations indicate that the bias increases with the percentage of fast guesses and with the latency difference between the lower tails of guess and nonguess RT distributions. Discarding and rerunning errors reduces bias somewhat, but a more elaborate “kill-the-twin” procedure reduces it much more. 相似文献

Proof-theoretic semantics is an alternative to model-theoretic semantics. It aims at explaining the meaning of the logical constants in terms of the inference rules that govern their behaviour in proofs. We argue that this must be construed as the task of explaining these meanings relative to a logic, i.e., to a consequence relation. Alas, there is no agreed set of properties that a relation must have in order to qualify as a consequence relation. Moreover, the association of a consequence relation to a logical calculus is not as straightforward as it may seem. We show that these facts are problematic for the proof-theoretic project but the problems can be solved. Our thesis is that the consequence relation relevant for proof-theoretic semantics is the one given by the sequent-to-sequent derivability relation in Gentzen systems.
AbstractThis paper investigates whether analytic philosophers who are non-native English speakers are subject to linguistic injustice and, if yes, what kind of injustice that is and whether it is different from the general disadvantage that non-native English speakers meet in a world where English is rapidly becoming the lingua franca. The paper begins with a critical review of the debate on linguistic justice, with a particular focus on the emergence of a lingua franca and the related questions of justice, both in terms of the disadvantages suffered by those groups who bear the cost of learning another language and in terms of forms of discrimination due to accents and language improprieties. We argue that being at a relative disadvantage compared to others does not necessarily translate in a proper injustice if fundamental civil, political and social provisions are in place. We suggest that a circumstance of injustice arises when such disadvantage affects those who are not yet members of such academic community such as prospective students, thus contributing in keeping the non-native group a minority. We qualify this case of disadvantage as a matter of structural injustice. 相似文献
