People are remarkably smart: They use language, possess complex motor skills, make nontrivial inferences, develop and use scientific theories, make laws, and adapt to complex dynamic environments. Much of this knowledge requires concepts and this study focuses on how people acquire concepts. It is argued that conceptual development progresses from simple perceptual grouping to highly abstract scientific concepts. This proposal of conceptual development has four parts. First, it is argued that categories in the world have different structure. Second, there might (...) be different learning systems that evolved to learn categories of differing structures. Third, these systems exhibit differential maturational course, which affects how categories of different structures are learned in the course of development. And finally, an interaction of these components may result in the developmental transition from perceptual groupings to more abstract concepts. This study reviews a large body of empirical evidence supporting this proposal. (shrink)

Although it is well documented that language plays an important role in cognitive development, there are different views concerning the mechanisms underlying these effects. Some argue that even early in development, effects of words stem from top‐down knowledge, whereas others argue that these effects stem from auditory input affecting attention allocated to visual input. Previous research (e.g., Robinson & Sloutsky, 2004a) demonstrated that non‐speech sounds attenuate processing of corresponding visual input at 8, 12, and 16 months of age, whereas (...) the current study demonstrates that words attenuate visual processing at 10 months but not at 16 months (Experiment 1). Furthermore, prefamiliarization with non‐speech sounds (Experiment 2) resulted in able processing of visual input by 16‐month‐olds. These findings suggest that some effects of labels found early in development may stem from familiarity with human speech. The possibility of general‐auditory factors underlying the effects of words on cognitive development is discussed. (shrink)

Numerous studies have found that selective attention affects category learning. However, previous research did not distinguish between the contribution of focusing and filtering components of selective attention. This study addresses this issue by examining how components of selective attention affect category representation. Participants first learned a rule‐plus‐similarity category structure, and then were presented with category priming followed by categorization and recognition tests. Additionally, to evaluate the involvement of focusing and filtering, we fit models with different attentional mechanisms to the data. (...) In Experiment 1, participants received rule‐based category training, with specific emphasis on a single deterministic feature (D feature). Experiment 2 added a recognition test to examine participants’ memory for features. Both experiments indicated that participants categorized items based solely on the D feature, showed greater memory for the D feature, were primed exclusively by the D feature without interference from probabilistic features (P features), and were better fit by models with focusing and at least one type of filtering mechanism. The results indicated that selective attention distorted category representation by highlighting the D feature and attenuating P features. To examine whether the distorted representation was specific to rule‐based training, Experiment 3 introduced training, emphasizing all features. Under such training, participants were no longer primed by the D feature, they remembered all features well, and they were better fit by the model assuming only focusing but no filtering process. The results coupled with modeling provide novel evidence that while both focusing and filtering contribute to category representation, filtering can also result in representational distortion.

The commentary discusses three components of the target proposal: (1) analogy as a host of phenomena, (2) relations as transformations, and (3) analogy as priming. The commentary argues that the first component is potentially productive, but it has yet to be fully developed, whereas the second and third components do not have an obvious way of accounting for multiple counterexamples.

Several attempts have recently been made to point to ‘the proper place’ for hydrogen in the Periodic Table of the elements. There are altogether five different types of arguments that lead to the following conclusions: hydrogen should be placed in group 1, above lithium; hydrogen should be placed in group 17, above fluorine; hydrogen is to be placed in group 14, above carbon; hydrogen should be positioned above both lithium and fluorine and hydrogen should be treated as a stand-alone element, (...) in the center of the Periodic Table. Although all proposals are based on arguments, not all of them sound equally convincing. An attempt is made, after critical reexamination of the arguments offered, to hopefully point to the best possible choice for the position of hydrogen. A few words are also mentioned on the structure of the Periodic Table and the attempts to reorganize it. (shrink)

The article discusses the attitude of Georg Lukács and his adherents who formed a circle “Techeniye” toward the phenomenon of Stalinism. Despite the political nature of the topic, the authors are aspired to provide an unbiased research. G. Lukács’ views on the theory and practice of Stalinism evolved over time. In the 1920s Lukács welcomes the idea of creation of socialism in one country and abandons the former revolutionary ideas expressed in his bookHistory and Class Consciousness. This turn is grounded (...) by new interpretation of Hegel as “realistic” thinker whose “realism” was shown in the aspiration to find “reconciliation” with reality and in denial of any utopias. The philosophical evolution leading to “realism” assumes integration of revolutionaries into the hierarchy of existing society. The article “Hölderlin’s Hyperion” represents attempt to justify Stalinism as a necessary and “progressive” phase of revolutionary development of the proletariat. Nevertheless, events of the second half of the 1930s force Lukács to realize the catastrophic nature of political strategy of Stalinism. In his works, Lukács ceases to analyze political topics and concentrates on problems of aesthetics and literary criticism. However, his aesthetic position allows to reconstruct the changed political views and to understand why he had earned the reputation of the “internal opponent” to Stalinism. After 1956, Lukács turns to political criticism of Stalinism, which nevertheless remains unilateral. He sees in Stalinism a kind of the left sectarianism, the theory and practice of the implementation of civil war measures in the era of peaceful co-existence of two systems. (shrink)

It is unclear how an argumentative environment would select for better reasoning given three general findings. First, argument rationality typically fails to persuade poor reasoners. Second, reasoned argumentation competes with more persuasive and less rational arguments for limited cognitive resources. Third, those poor at reasoning fail to distinguish between valid and invalid arguments. Reasoning, therefore, is poorly designed for argument.

The article draws a conceptual distinction the (French) structuralism of the 50’s–60’s and the post-structuralism of the 70’s, which are discussed as overlapping in their intellectual paths; their mutual dynamics is defined as a reaction of the intelligence to the pressure of depersonalized unified schemes within the logic of structuralism against free improvisation and loose interpretation instead of total explanations in the post-structuralism interpretation. The article establishes a conceptual identity of the paradoxical nature between post-structuralism (and deconstructionism, which is homogeneous (...) and identical thereto in a number of aspects), on the one hand, and constructionism with its specific process of language dismantling – social/ideological languages, social group dialects, on the other hand, which naturally leads the authors to the analysis of the paradoxicality principles, defined by post-structuralism (five principles of paradoxicality of Gilles Deleuze – paradox of regress, paradox of sterile reiteration, paradox of neutrality, paradox of absurd, paradox of Levi-Strauss); poststructuralists’ paralogisms are examined through paradoxical denotation; the late Roland Barthes’ phenomenon of paradoxicality, becoming a plot-forming principle of narration, is analyzed. Poststructuralism is conceptualized in the article as the first decisive step of post-modernism; the affinity of post-structuralist and postmodernist commitment to parody, game and irony is stated; the theory of language games in post-modern interpretation is explored; one of those games – a game of carnival – is explored within the diachronic retrospective; the affinity of parody and carnival tradition of post-structuralism and post-modernism to the romantic irony of the XIXth century and its inconsistency with the popular culture of laugh is established. The genesis of poststructuralism and post-modernism is connected with the ideological restart of the Western society before the “very end” of the Resistance ideas and the disappointment of the left European intellectuals in the “great legends” and illusions of Marxism. The blurred concepts of relativism are connected with the mutual disproportion of different layers of historical experience. (shrink)

Felix Klein and Abraham Fraenkel each formulated a criterion for a theory of infinitesimals to be successful, in terms of the feasibility of implementation of the Mean Value Theorem. We explore the evolution of the idea over the past century, and the role of Abraham Robinson's framework therein.

Rare copy number variants have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large CNVs at several loci, including microdeletions at 1q21.1, 3q29, 15q13.3 and 22q11.2 and microduplication at 16p11.2. However, these CNVs collectively account for a small fraction of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy (...) number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 patients versus 2 of 7,431 controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs. © 2011 Macmillan Publishers Limited.

This book assesses how Vatican II opened up the Catholic Church to encounter, dialogue, and engagement with other world religions. Opening with a contribution from the President of the Pontifical Council for Interreligious Dialogue, Cardinal Jean-Louis Tauran, it next explores the impact, relevance, and promise of the Declaration Nostra Aetate before turning to consider how Vatican II in general has influenced interfaith dialogue and the intellectual and comparative study of world religions in the postconciliar decades, as well as the contribution (...) of particular past and present thinkers to the formation of current interreligious and comparative theological methods. Additionally, chapters consider interreligious dialogue vis-à-vis theological anthropology in conciliar documents; openness to the spiritual practices of other faith traditions as a way of encouraging positive interreligious encounter; the role of lay and new ecclesial movements in interreligious dialogue; and the development of Monastic Interreligious Dialogue. Finally, it includes a range of perspectives on the fruits and future of Vatican’s II’s opening to particular faiths such as Judaism, Islam, Hinduism, and Buddhism. (shrink)

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

ABSTRACTThe social content of affective stimuli has been proposed as having an influence on cognitive processing and behaviour. This research was aimed, therefore, at studying whether automatic exogenous attention demanded by affective pictures was related to their social value. We hypothesised that affective social pictures would capture attention to a greater extent than non-social affective stimuli. For this purpose, we recorded event-related potentials in a sample of 24 participants engaged in a digit categorisation task. Distracters were affective pictures varying in (...) social content, in addition to affective valence and arousal, which appeared in the background during the task. Our data revealed that pictures depicting high social content captured greater automatic attention than other pictures, as reflected by the greater amplitude and shorter latency of anterior P2, and anterior and posterior N2 components of the ERPs. In addition, social content also provoked greater allocation of processing resour... (shrink)

One of the vividly discussed topics in the contemporary philosophy of science (especially physics) is the opposition between realism and Anti-Realism. The supporters of the first way of thinking trust in the objective existence of realities studied by science. They consider theories as approximate descriptions of these realities (Psillos 1999, xvii), whereas their opponents do not. However, both sides base their argumentation on simplified notions of scientific theories. In this paper, we present a more general approach, which can be coined (...) as “Theoretical Physics Realism” (TPR). It is based on the detailed reconstruction of the polysystemic nature of physical theories. The consequences of this reconstruction for understanding the genuine relationship between theories and experiments in studying the realities are indicated. The paper distinguishes between abstract (general) and domain-dependent theories and appeals to specific physical theories together with their application domains rather than to general speculations.
