Ecological and sensorimotor theories of perception build on the notion of action-dependent invariants as the basic structures underlying perceptual capacities. In this paper we contrast the assumptions these theories make on the nature of perceptual information modulated by action. By focusing on the question, how movement specifies perceptual information, we show that ecological and sensorimotor theories endorse substantially different views about the role of action in perception. In particular we argue that ecological invariants are characterized with reference to transformations produced in the sensory array by movement: such invariants are transformation-specific but do not imply motor-specificity. In contrast, sensorimotor theories assume that perceptual invariants are intrinsically tied to specific movements. We show that this difference leads to different empirical predictions and we submit that the distinction between motor equivalence and motor-specificity needs further clarification in order to provide a more constrained account of action/perception relations. 相似文献

This article critically examines four specific aspects of Avner de Shalit’s book Cities and Immigration. First, it argues that the influx of cosmopolitan migrants, which de Shalit considers unproblematic for destination cities, may in fact pose a challenge to some cities’ ethos, and to the ethos of specific neighbourhoods within cities. Second, it contends that gentrification, contrary to what de Shalit suggests, may sometimes hinder rather than promote social mixing and migrants' integration. Third, it claims that most of the examples of mutual assimilation (de Shalit’s preferred model of inclusion) provided by de Shalit concern superficial interactions and exchanges between members of different groups. This raises both the empirical question of whether deeper forms of mutual assimilation are possible and the normative question of whether they are desirable. Fourth, it takes issue with two concrete policy recommendations advanced by de Shalit: the first involves assessing potential matchings between source and destination cities in order to advise migrants where to move; the second concerns prioritizing immigrants who might be better capable than others of facilitating the integration of future immigrants, due to their values, religion, or country of origin. 相似文献

We present the logic BLChang, an axiomatic extension of BL (see [23]) whose corresponding algebras form the smallest variety containing all the ordinal sums of perfect MV-chains. We will analyze this logic and the corresponding algebraic semantics in the propositional and in the first-order case. As we will see, moreover, the variety of BLChang-algebras will be strictly connected to the one generated by Chang’s MV-algebra (that is, the variety generated by all the perfect MV-algebras): we will also give some new results concerning these last structures and their logic. 相似文献

We studied the time course of material categorization in natural images relative to superordinate and basic-level object categorization, using a backward-masking paradigm. We manipulated several low-level features of the images—including luminance, contrast, and color—to assess their potential contributions. The results showed that the speed of material categorization was roughly comparable to the speed of basic-level object categorization, but slower than that of superordinate object categorization. The performance seemed to be crucially mediated by low-level factors, with color leading to a solid increase in performance for material categorization. At longer presentation durations, material categorization was less accurate than both types of object categorization. Taken together, our results show that material categorization can be as fast as basic-level object categorization, but is less accurate. 相似文献

In this study, the authors aim to clarify whether the subject–object asymmetry in relative clause comprehension is due to the use of parsing strategies (Active Filler Theory) or to a greater memory load generated by object sentences. Two experiments investigate how individual differences in working memory span may influence the reading times of relative sentences in Italian, a language characterized by a flexible structure. The results of Experiment 1 indicate that object extraction is more complex than subject extraction when sentences have a canonical structure. Furthermore, low-span participants have particular difficulties with object relative sentence comprehension. The results of Experiment 2 show that subject-relative clauses with uncanonical structures are more complex to understand than object-relative clauses, and low-span participants have more difficulties than high-span participants in elaborating both subject and object relative clauses. These data seem to be coherent with the Active Filler Theory. 相似文献

Although the role of emotion in socioeconomic decision making is increasingly recognised, the impact of specific emotional disorders, such as anxiety disorders, on these decisions has been surprisingly neglected. Twenty anxious patients and twenty matched controls completed a commonly used socioeconomic task (the Ultimatum Game), in which they had to accept or reject monetary offers from other players. Anxious patients accepted significantly more unfair offers than controls. We discuss the implications of these findings in light of recent models of anxiety, in particular the importance of interpersonal factors and assertiveness in an integrated model of decision making. Finally, we were able to show that pharmacological serotonin used to treat anxious symptomatology tended to normalise decision making, further confirming and extending the role of serotonin in co-operation, prosocial behaviour, and social decision making. These results show, for the first time, a different pattern of socioeconomic behaviour in anxiety disordered patients, in addition to the known memory, attentional and emotional biases that are part of this pathological condition. 相似文献

In this article I consider Cécile Laborde's response to the semantic and Protestant critiques of liberalism's approach to religion. In Section 1 I examine the complex relationship between language and religion that emerges from Laborde's response to the semantic critique. In Section 2 I argue that Laborde's response to the Protestant critique either fails on its own terms or is in tension with her response to the semantic critique. Finally, in Section 3 I critically reflect on the negative conception of freedom that underlies Laborde's response to the Protestant critique, and ask how this can be reconciled with the republican understanding of freedom that characterises Laborde's earlier work. 相似文献

Political parties have only recently become a subject of investigation in political theory. In this paper I analyse religious
political parties in the context of John Rawls’s political liberalism. Rawlsian political liberalism, I argue, overly constrains
the scope of democratic political contestation and especially for the kind of contestation channelled by parties. This restriction
imposed upon political contestation risks undermining democracy and the development of the kind of democratic ethos that political
liberalism cherishes. In this paper I therefore aim to provide a broader and more inclusive understanding of ‘reasonable’
political contestation, able to accommodate those parties (including religious ones) that political liberalism, as customarily
understood, would exclude from the democratic realm. More specifically, I first embrace Muirhead and Rosenblum’s (Perspectives
on Politics 4: 99–108 2006) idea that parties are ‘bilingual’ links between state and civil society and I draw its normative
implications for party politics. Subsequently, I assess whether Rawls’s political liberalism is sufficiently inclusive to
allow the presence of parties conveying religious and other comprehensive values. Due to Rawls’s thick conceptions of reasonableness
and public reason, I argue, political liberalism risks seriously limiting the number and kinds of comprehensive values which
may be channelled by political parties into the public political realm, and this may render it particularly inhospitable to
religious political parties. Nevertheless, I claim, Rawls’s theory does offer some scope for reinterpreting the concepts of
reasonableness and public reason in a thinner and less restrictive sense and this may render it more inclusive towards religious
partisanship. 相似文献
