Localist models of spreading activation (SA) and models assuming distributed representations offer very different takes on semantic priming, a widely investigated paradigm in word recognition and semantic memory research. In this study, we implemented SA in an attractor neural network model with distributed representations and created a unified framework for the two approaches. Our models assume a synaptic depression mechanism leading to autonomous transitions between encoded memory patterns (latching dynamics), which account for the major characteristics of automatic semantic priming in (...) humans. Using computer simulations, we demonstrated how findings that challenged attractor‐based networks in the past, such as mediated and asymmetric priming, are a natural consequence of our present model’s dynamics. Puzzling results regarding backward priming were also given a straightforward explanation. In addition, the current model addresses some of the differences between semantic and associative relatedness and explains how these differences interact with stimulus onset asynchrony in priming experiments.

Semantic priming has long been recognized to reflect, along with automatic semantic mechanisms, the contribution of controlled strategies. However, previous theories of controlled priming were mostly qualitative, lacking common grounds with modern mathematical models of automatic priming based on neural networks. Recently, we introduced a novel attractor network model of automatic semantic priming with latching dynamics. Here, we extend this work to show how the same model can also account for important findings regarding controlled processes. Assuming the rate of semantic (...) transitions in the network can be adapted using simple reinforcement learning, we show how basic findings attributed to controlled processes in priming can be achieved, including their dependency on stimulus onset asynchrony and relatedness proportion and their unique effect on associative, category-exemplar, mediated and backward prime-target relations. We discuss how our mechanism relates to the classic expectancy theory and how it can be further extended in future developments of the model. (shrink)

Previous studies suggested that emotions can be correctly interpreted from facial expressions in the absence of conscious awareness of the face. Our goal was to explore whether subordinate information about a face’s gender and race could also become available without awareness of the face. Participants classified the race or the gender of unfamiliar faces that were ambiguous with regard to these dimensions. The ambiguous faces were preceded by face-images that unequivocally represented gender and race, rendered consciously invisible by simultaneous continuous-flash-suppression. (...) The classification of ambiguous faces was biased away from the category of the adaptor only when it was consciously visible. The duration of subjective visibility correlated with the aftereffect strength. Moreover, face identity was consequential only if consciously perceived. These results suggest that while conscious awareness is not needed for basic level categorization, it is needed for subordinate categorization. Emotional information might be unique in this respect.

Words become associated following repeated co-occurrence episodes. This process might be further determined by the semantic characteristics of the words. The present study focused on how semantic and episodic factors interact in incidental formation of word associations. First, we found that human participants associate semantically related words more easily than unrelated words; this advantage increased linearly with repeated co-occurrence. Second, we developed a computational model, SEMANT, suggesting a possible mechanism for this semantic-episodic interaction. In SEMANT, episodic associations are implemented through (...) lateral connections between nodes in a pre-existent self-organized map of word semantics. These connections are strengthened at each instance of concomitant activation, proportionally with the amount of the overlapping activity waves of activated nodes. In computer simulations SEMANT replicated the dynamics of associative learning in humans and led to testable predictions concerning normal associative learning as well as impaired learning in a diffuse semantic system like that characteristic of schizophrenia.

With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...) the understanding of facial expressions of emotions. Prices of sticking with the modal view, and advantages of an expanded view, are succinctly reviewed. (shrink)

Alan Turing’s 1950 imitation game has been widely understood as a means for testing if an entity is intelligent. Following a series of papers by Diane Proudfoot, I offer a socio-technological interpretation of Turing’s paper and present an alternative way of understanding both the imitation game and Turing’s concept of intelligence. Turing, I claim, saw intelligence as a social concept, meaning that possession of intelligence is a property determined by society’s attitude toward the entity. He realized that as long as (...) human society held a prejudiced attitude toward machinery—seeing machines a priori as mindless objects—machines could not be said to be intelligent, by definition. He also realized, though, that if humans’ a priori, chauvinistic attitude toward machinery changed, the existence of intelligent machines would become logically possible. Turing thought that such a change would eventually occur: He believed that when scientists overcome the technological challenge of constructing sophisticated machines that could imitate human verbal behavior—i.e., do well in the imitation game—humans’ prejudiced attitude toward machinery will have altered in such a way that machines could be said to be intelligent. The imitation game, for Turing, was not an intelligence test, but a technological aspiration whose realization would likely involve a change in society’s attitude toward machines. (shrink)

This paper presents a new approach to the demarcation of social emotions, based on their dependence on social appraisals that are designed to assess events bearing on social concerns. Previous theoretical attempts to characterize social emotions are compared, and their inconsistencies highlighted. Evidence for the present formulation is derived from theory and research into links between appraisals and emotions. Emotions identified as social using our criteria are also shown to bring more consistent consequences for social behavior than nonsocial emotions. We (...) conclude by considering ways of validating and refining our classification. (shrink)

Weiner’s attribution theory of motivation and emotion assumes emotions are determined by beliefs about causality. Individuals share a naïve understanding of this linkage between causal attribution and emotions and use it in order to draw inferences from and influence others’ emotions. Evidence for such uses is provided and recent research and theory that goes beyond the attribution–emotion linkage is discussed. Specifically, recent research considers the naïve use of a larger set of emotions and appraisals and their connections, and the role (...) of context in this process. However, still missing is a fuller understanding when this naïve knowledge is employed and how and when it is based on an explicit understanding of the emotion–appraisal linkage rather than more automatic processes.

Libertarian paternalism's notion of “nudging” refers to steering individual decision making so as to make choosers better off without breaching their free choice. If successful, this may offer an ideal synthesis between the duty to respect patient autonomy and that of beneficence, which at times favors paternalistic influence. A growing body of literature attempts to assess the merits of nudging in health care. However, this literature deals almost exclusively with health policy, while the question of the potential benefit of nudging (...) for the practice of informed consent has escaped systematic analysis. This article focuses on this question. While it concedes that nudging could amount to improper exploitation of cognitive weaknesses, it defends the practice of nudging in a wide range of other conditions. The conclusion is that, when ethically legitimate, nudging offers an important new paradigm for informed consent, with a special potential to overcome the classical dilemma between paternalistic beneficence and respect for autonomy.

There is a disturbing kind of situation that presents agents with only two possibilities of moral action—one especially praiseworthy, the other condemnable. I describe such scenarios and argue that moral action in them exhibits a unique set of parameters: performing the commendable action is especially praiseworthy; not performing is not blameworthy; not performing is wrong. This set of parameters is distinct from those which characterize either moral obligation or supererogation. It is accordingly claimed that it defines a distinct, yet unrecognized, (...) deontic category, to which the name ‘Forced Supererogation’ is appropriate. The moral parameters of Forced Supererogation and the relations between them are discussed, especially the divergence of wrongness and blame. I argue that this new category allows a more accurate classification of moral actions than that imposed by the strained dichotomy of obligation versus supererogation. (shrink)

The nonidentity problem is a deep puzzle challenging the moral intuition that what is bad must be bad for someone. The first part of the paper constructs a new theory of harming, whereas the second part builds on the conclusions of the first to offer a new solution to the NIP. The first part discusses the neglected question of when a burden inflicted in the context of overall benefitting can be discretized as a separate entity—only when it can, is it (...) possible to identify the burden as harm, and only then is it possible to harm in bringing into overall good existence. The second part explains how, in those cases where creating is indeed harming, we can use the logic of concept expansion to construct a concept of wronging that applies to creation cases. (shrink)

Recent research, especially with functional brain imaging, demonstrated cases where the administration of a placebo produces objective effects in tissues that are indistinguishable from those of the real therapeutic agents. This phenomenon has been shown in treatments of pain, depression, Parkinsonism, and more. The main ethical complaint against placebo treatment is that it is a kind of deception, where supposedly we substitute what works just psychologically for a real drug that actually works on the tissue level. We claim that the (...) scientific findings bring to a new level the seeming deconstruction of the distinction between “placebo” and “real” drugs, and that instances of placebo treatment which fulfill this criterion should be recognized as a unique category—we call it “comparable placebo treatment” (CPT). The paper uses an analysis of the notion of deception to argue that CPT does not amount to deception; that it can preserve patient autonomy; and that it is therefore morally legitimate. (shrink)

ABSTRACTThis paper introduces the category of ‘non-deceptive manipulation that causes false beliefs’, analyzes how it narrows the traditional scope of ‘deception’, and draws moral implications.

The acclaimed and controversial historian turns his critical gaze on the writing of history today. Drawing on his four decades as a professional historian, Shlomo Sand interrogates the academic discipline of history, whose origin lay in the need for a national ideology. In the last few decades, traditional history has begun to fragment, yet only to give rise to a new role of historians as priests of official memory. Working in Israel has sharpened Sand's perspective, since the role of (...) history as national myth is particularly salient in a country where the Bible is treated as a history book. He asks such questions as: Is every historical narrative ideologically marked? Do political requirements and state power weigh down inordinately on historical research and teaching? And, in such conditions, can there be a morally neutral and 'scientific' truth? Despite his trenchant criticism of academic history, Sand would still like to believe that the past can be understood without myth, and sees pointers for this in the work of Weber and Sorel"--Provided by publisher.

“de-extinction” refers to the process of resurrecting extinct species by genetic methods. This science-fiction-sounding idea is in fact already in early processes of scientific implementation. Although this recent “revival of the dead” raises deep ethical questions, the ethics of de-extinction has barely received philosophical treatment. Rather than seeking a verdict for or against de-extinction, this paper attempts an overview and some novel analyses of the main ethical considerations. Five dimensions of the ethics of de-extinction are explored: (a) the possible contribution (...) of de-extinction to promoting ecological values, (b) the deontological argument that we owe de-extinction to species we rendered extinct, (c) the question of “playing God” through de-extinction, (d) the utilitarian perspective, and (e) the role of aesthetic considerations in the ethics of de-extinction. A general feature arising from the paper’s discussion is that, due to de-extinction’s special character, it repeatedly tests the limits of our ethical notions. (shrink)

The nocebo effect, the mirror-phenomenon to the placebo effect, is when the expectation of a negative outcome precipitates the corresponding symptom or leads to its exacerbation. One of the basic ethical duties in health care is to obtain informed consent from patients before treatment; however, the disclosure of information regarding potential complications or side effects that this involves may precipitate a nocebo effect. While dilemmas between the principles of respect for patient autonomy and of nonmaleficence are recognized in medical ethics, (...) there has not yet been an ethical discussion focused on the potential dilemma raised by the nocebo effect of informed consent. This dilemma is especially pernicious, since it involves a direct causality of harm by the caregiver that is unparalleled by other potential harmful effects of information disclosure. This paper articulates the dilemma of the NEIC and offers a seminal ethical analysis. (shrink)

Ever since the discovery of Marx's Early Writings, most of the literature concerned with Marx's intellectual development has centred around the so-called gap between the 'young' Marx, who was considered to be a humanist thinker, and the 'older' Marx, who was held to be a determinist with little concern for anything outside his narrow theory of historical materialism. Dr Avineri claims that such a gap between the 'young' and 'older' Marx did not exist. He supports his claim by a detailed (...) study of the whole corpus of Marx's writing on social and political thought. (shrink)

This study in English of Hegel's political philosophy presents an overall view of the development of Hegel's political thinking. The author has drawn on Hegel's philosophical works, his political tracts and his personal correspondence. Professor Avineri shows that although Hegel is primarily thought of as a philosopher of the state, he was much concerned with social problems and his concept of the state must be understood in this context.

John Rawls, father of contemporary distributive justice, professed the metaphysical neutrality of his theory, and formulated an additional theory to support such neutrality generally. This article exposes Rawls’s own theological underpinnings concerning his conception of the moral arbitrariness of existence, and his structural dichotomous approach for engaging it. I show how both of his theories are reminiscent of Calvin, employing methods of bifurcation, and thus generating tensions within both the concept of justice and moral personality. I end with analysis of (...) the relationship of this structural rationality to arbitrariness. This exposure of Rawls’s theological debt is part of a wider argument concerning the theological basis of distributive justice theory, and the relevance of Theology for philosophical ethics.

Luck egalitarianism is an approach within current distributive justice theory which aims to focus redistributive efforts solely upon disadvantages that ensue from bad luck. This article considers how central assumptions and themes of both luck egalitarianism and its critics parallel those of providence theology and share some of their concerns. These relate to problems such as the basis of equality, the extent and nature of our knowledge, and of course, the paternalism that assessing people’s responsibility over their own disadvantages involves. (...) I highlight the similarity of luck egalitarianism to the role of providence and providence theory thinking, and particularly the tension between egalitarianism as a theological concept and the condescension inherent to imitatio Dei ethics. I approach these issues by analyzing standard criticisms of the luck egalitarian project, espoused by Susan Hurley and Elizabeth Anderson. I then proceed to assess the values of luck egalitarianism itself and consider different models of providence, and the meaning of this analysis for normative ethics. The subject matter of this article is part of a wider comparison of distributive justice and providence theory, within which luck egalitarianism affords a very fruitful and highly relevant case study.

This article argues that the religious epistemology of the rabbinic tradition, which preserves and respects multiple perspectives in intellectual debate, is best understood in comparison to the definitions of truth proposed by philosophical pragmatists, in particular William James and W. V. Quine, and in contrast to those of philosophical liberals, in particular J. S. Mill. Both the rabbis and the pragmatists emphasize the harmony that innovation must maintain with extant webs of meaning. Conceptions of objectivity and subjectivity in Jewish medieval (...) rationalism and in early modern mysticism are considered and compared with those of latter-day European and American epistemology. This article makes a case for a fundamentally pluralistic conception of truth and argues that it is exemplified in the social interaction of the talmudic sages. (shrink)
