Schönberg’s Judaism from Notes to Thought and from Thought to Notes

What concept of Judaism is present in Schönberg’s philosophy of music? It is impossible to separate the musical texture from his experience of reconciliation with Judaism, and his new idea of musical drama is a confirmation that the dodecaphonic structure of musical thinking connects with Schönberg’s idea of the Jewish ethical and religious point of view. A comparative analysis of some essays with some operas shows the internal tie between music and Judaism in dodecaphony.     

Completeness: from Gödel to Henkin

This paper focuses on the evolution of the notion of completeness in contemporary logic. We discuss the differences between the notions of completeness of a theory, the completeness of a calculus, and the completeness of a logic in the light of Gödel's and Tarski's crucial contributions.We place special emphasis on understanding the differences in how these concepts were used then and now, as well as on the role they play in logic. Nevertheless, we can still observe a certain ambiguity in the use of the close notions of completeness of a calculus and completeness of a logic. We analyze the state of the art under which Gödel's proof of completeness was developed, particularly when dealing with the decision problem for first-order logic. We believe that Gödel had to face the following dilemma: either semantics is decidable, in which case the completeness of the logic is trivial or, completeness is a critical property but in this case it cannot be obtained as a corollary of a previous decidability result. As far as first-order logic is concerned, our thesis is that the contemporary understanding of completeness of a calculus was born as a generalization of the concept of completeness of a theory. The last part of this study is devoted to Henkin's work concerning the generalization of his completeness proof to any logic from his initial work in type theory.     

Patriotism: from Twardowski to Bocheński

In my paper, I show three concepts of patriotism present in the Lvov-Warsaw School, and try to indicate how these concepts differed and what norms they were involved in, as well as to evaluate the justifications indicated for these norms.

     

Are spatial frequencies integrated from coarse to fine?

The existence of a temporal anisotropy in the integration of spatial frequencies, such that spatial frequencies are integrated more effectively if they are available from low to high through time, has been examined in a series of experiments. In the first experiment, the first three harmonics of a square wave were presented in a low-to-high or a high-to-low sequence in a temporal two-interval forced-choice experiment. Subjects were asked to indicate which sequence appeared to resemble a square wave more. A high-to-low sequence of spatial frequencies was judged to more resemble the target than the low-to-high sequence. These results support a temporal anisotropy in the integration of spatial frequencies of exactly the opposite form to that suggested from previous results. Further experiments established that this was not due to task differences or to subjects basing their decision on the final spatial frequency shown. An interpretation is offered in which an isotropic mechanism for spatial-frequency integration is combined with a recency bias.     

How to refrain from answering Kripke’s puzzle

In this paper, I investigate the prospects for using the distinction between rejection and denial to resolve Saul Kripke??s puzzle about belief. One puzzle Kripke presents in ??A Puzzle About Belief?? poses what would have seemed a fairly straightforward question about the beliefs of the bilingual Pierre, who is disposed to sincerely and reflectively assent to the French sentence ??Londres est jolie??, but not to the English sentence ??London is pretty??, both of which he understands perfectly well. The question to be answered is whether Pierre believes that London is pretty, and Kripke argues, of each answer, that it is unacceptable. On my proposal, either answer to the question is to be rejected, but neither answer is to be denied, using the resource of partially-defined predicates. After demonstrating how this serves as a solution to the puzzle, I illustrate some philosophical motivations??independent of Kripke??s puzzle??for adopting a view on which belief is a partially defined predicate. I conclude that there are decent prospects for the proposed response to Kripke??s puzzle.     

On Sterba’s Argument from Rationality to Morality

James Sterba argues for morality as a principled compromise between self-regarding and other-regarding reasons (Morality as Compromise) and that either egoists or altruists, who always give overriding weight to self-regarding and other-reasons, respectively, can be shown to beg the question against morality. He concludes that moral conduct is “rationally required.” Sterba’s dialectic assumes that both egoists and altruists accept that both self-regarding and other-regarding considerations are genuine pro tanto reasons, but then hold that their respective reasons always outweigh. Against this, I argue that egoists would most plausibly deny that non-self-regarding considerations have even pro tanto weight. I argue, also, that even if both sides grant the pro tanto weight of their opponent’s reasons, Sterba is mistaken in holding that only Morality as Compromise provides a “non-question-begging resolution” of what it is rational to do when self-regarding and other-regarding reasons conflict, since it might be that it is rational to act on either. It might be that the weightiest self-regarding and the weightiest other-regarding reasons in the case are both sufficient reasons for acting without either being conclusive. The essay ends with a sketch of arguments against egoism that I take to be more plausible than Sterba’s. As I have argued elsewhere, what makes an agent’s own welfare or her own concerns or interests normative for her simultaneously makes them normative for others as well.     

Learning to learn from video? 30-month-olds benefit from continued use of supportive scaffolding

Young children struggle to learn new words presented on video, but adult co-viewers can support them by providing scaffolds that explicitly connect the video and real world. In this study, we asked whether scaffolding facilitates children’s symbolic understanding of the video, such that they will subsequently transfer labels from video to real referents. Sixty-three 30-month-olds and 61 36-month-olds participated in a series of three word learning trials in one of three conditions. In the supportive condition, an in-person adult explicitly drew connections between each on-screen object and the corresponding real object in the room with the child. In the unsupportive condition, the in-person adult provided similar-length statements about the objects but did not draw connections between them. In the partial scaffold condition, the in-person adult provided the supportive scaffolds for the first two trials and the unsupportive version for the third trial. At 30 months, children selected the correct object on the third trial more often in the supportive than the unsupportive scaffold condition, and performance in the partial scaffold condition fell in between. At 36 months, performance on the third trial did not differ across conditions. The results showed that experiencing the scaffold twice was not enough to reliably support 30-month-olds in learning to think symbolically on the third trial; rather, they appeared to rely on the adult to connect the video image with its specific real-world referent. At 36 months, however, children did not rely on the adult scaffold to apply the video label to the real-world objects.     

Does the Argument from Realization Generalize? Responses to Kim

By quantifying over properties we cannot create new properties any more than by quantifying over individuals we can create new individuals. Someone murdered Jones, and the murderer is either Smith or Jones or Wang. That “someone,” who murdered Jones, is not a person in addition to Smith, Jones, and Wang, and it would be absurd to posit a disjunctive person, Smith‐or‐Jones‐or‐Wang, with whom to identify the murderer. The same goes for second‐order properties and their realizers. (Kim 1997a, 201)     

Anxiety and motor performance: Where to from here?

Abstract

The purpose of this paper was to briefly review the traditional existing theories attempting to explain the relationship between anxiety and motor performance and then suggest some future directions for research. Specifically, a review of drive theory and the inverted-U hypothesis led to the conclusion that due to methodological, conceptual and interpretive problems, these explanations for the anxiety-performance relationship are overly simplistic and lack heuristic value. Future research should focus on the interaction of psychobiological states as they relate to motor performance. Some specific suggestions include more precision in the measurement of anxiety as a multidimensional construct which includes psychophysiological, cognitive, and affective components. In addition, individual differences need to be recognized with intraindividual comparisons replacing between-subject comparisons. Hanin's zone of optimal functioning is offered as one such approach. Finally, more sensitivity and precision is needed in the measurement of performance by employing both qualitative and quantitative methodologies.     

Is there a causal link from phonological awareness to success in learning to read?

In this review, we re-assess the evidence that phonological awareness represents a skill specific to spoken language that precedes and directly influences the process of reading acquisition. Longitudinal and experimental training studies are examined in detail, as these are considered most appropriate for exploring a causal hypothesis of this nature. A particular focus of our analysis is the degree to which studies to date have controlled for existing literacy skills in their participants and the influence that these skills might have on performance on phonological awareness tasks. We conclude that no study has provided unequivocal evidence that there is a causal link from competence in phonological awareness to success in reading and spelling acquisition. However, we believe that such a study is possible and outline some ideas for its design and implementation.     

Is it always fallacious to derive values from facts?

Since the time of David Hume, many philosophers have held that there is a logical Is/Ought gap. According to the doctrine of the Is/Ought gap, there are no valid (i.e., non-fallacious) arguments from purely factual premises about whatis the case to moral or normative conclusions about whatought to be. Occasionally, this doctrine has been challenged, but frequently it has been accepted without argumentation. Charles Pigden has recently argued for a logical Is/Ought gap on the grounds of the conservativeness of logic. I offer a counter-example which shows that Pigden's argument is unsound and that there need be no logical gap between Is-premises and an Ought-conclusion. My counter-example is an argument which is logically valid, has only Is-premises and an Ought-conclusion, and does not purport to violate the conservativeness of logic. Moreover, my argument does not rely, as other alleged counter-examples do, on controversial assumptions from Aristotelian biology about natures or ends, or about institutions such as promise-making.

Why do people sacrifice to approach rewards versus to avoid costs? Insights from attachment theory

This research provides the first empirical investigation of how attachment orientations contribute to approach and avoidance goals for engaging in sacrifice. Study 1 is a cross‐sectional study of individuals in dating relationships, and Study 2 is a 14‐day daily experience study of dating couples. Results showed that attachment anxiety was associated with a greater frequency of sacrifice and more willingness to sacrifice for approach goals (particularly self‐focused goals) and avoidance goals. Attachment avoidance was associated with a lower frequency of sacrifice, less willingness to sacrifice for approach goals (particularly partner‐focused goals), and more willingness to sacrifice for avoidance goals (both self‐ and partner‐focused). Daily sacrifice goals were also associated with the partner's attachment orientation. Theoretical and practical implications are discussed.     

Childhood problem behaviours as precursors of drinking to intoxication trajectories – from age 1.5 to 19

Objective: We examined behaviour problem precursors (i.e. internalising and externalising) in childhood (ages 1.5 to 8.5) and early adolescence (age 12.5) and consequences (i.e. harmful alcohol use) in emerging adulthood (age 19), of developmental trajectories of drinking to intoxication across adolescence (ages 14.5–19).

Design and outcome measures: Data from 921 children and their parents followed for 18 years from the population-based Tracking Opportunities and Problems (TOPP) Study were used to examine adolescent trajectories of drinking to intoxication. Logistic regression was used to examine predictors of trajectory group membership.

Results: We identified 3 trajectory classes: low / abstainer (41%), late onset high (31%) and early onset high (28%) using latent class analyses. Logistic regression analyses showed that childhood high externalising characterised early onset of intoxication vs. other classes, while early adolescence externalising discriminated both early and late onset of intoxication. High early childhood internalising characterised those consistently low or abstinent on alcohol intoxication, while early adolescent internalising characterised those having an early onset of intoxication. However, after additional adjustment for co-occurring externalising, there were no evidence for a link between early adolescent internalising and intoxication.

Conclusions: The findings suggest that both child and early adolescent-focused prevention efforts may be warranted.     

Where to from here? On the future development of autonomous vehicles from a cognitive systems perspective

Self-driving cars not only solve the problem of navigating safely from location A to location B; they also have to deal with an abundance of (sometimes unpredictable) factors, such as traffic rules, weather conditions, and interactions with humans. Over the last decades, different approaches have been proposed to design intelligent driving systems for self-driving cars that can deal with an uncontrolled environment. Some of them are derived from computationalist paradigms, formulating mathematical models that define the driving agent, while other approaches take inspiration from biological cognition. However, despite the extensive work in the field of self-driving cars, many open questions remain. Here, we discuss the different approaches for implementing driving systems for self-driving cars, as well as the computational paradigms from which they originate. In doing so, we highlight two key messages: First, further progress in the field might depend on adapting new paradigms as opposed to pushing technical innovations in those currently used. Specifically, we discuss how paradigms from cognitive systems research can be a source of inspiration for further development in modelling driving systems, highlighting emergent approaches as a possible starting point. Second, self-driving cars can themselves be considered cognitive systems in a meaningful sense, and are therefore a relevant, yet underutilized resource in the study of cognitive mechanisms. Overall, we argue for a stronger synergy between the fields of cognitive systems and self-driving vehicles.     

What's to Fear from Immigrants? Creating an Assimilationist Threat Scale

We argue that cultural threat, stressed in recent studies of anti-immigrant sentiment, is properly measured in the U.S. case as "assimilationist threat": a resentful perception that immigrants are failing to adopt the cultural norms and lifestyle of their new homeland. We explore the meaning and form of assimilationist threat in the minds of Americans through an analysis of four focus groups, two in Los Angeles, CA, and two in Columbus, OH. Using information from the focus groups, we develop and test a set of survey questions covering three dimensions of immigrants' commitment to their new country: language, productivity, and citizenship. We produce a summary scale of assimilationist threat that can be used by other researchers seeking to understand the causes and consequences of anti-immigrant sentiment.     

Is There an Effective Approach to Deterring Students from Plagiarizing?

The purpose of this study was to evaluate the effectiveness of plagiarism detection software and penalty for plagiarizing in detecting and deterring plagiarism among medical students. The study was a continuation of previously published research in which second-year medicals students from 2001/2002 and 2002/2003 school years were required to write an essay based on one of the four scientific articles offered by the instructor. Students from 2004/2005 (N = 92) included in present study were given the same task. Topics of two of the four articles were considered less complex, and two were more complex. One less and one more complex articles were available only as hardcopies, whereas the other two were available in electronic format. The students from 2001/2002 (N = 111) were only told to write an original essay, whereas the students from 2002/2003 (N = 87) were additionally warned against plagiarism, explained what plagiarism was, and how to avoid it. The students from 2004/2005 were warned that their essays would be examined by plagiarism detection software and that those who had plagiarized would be penalized. Students from 2004/2005 plagiarized significantly less of their essays than students from the previous two groups (2% vs. 17% vs. 21%, respectively, P < 0.001). Over time, students more frequently choose articles with more complex subjects (P < 0.001) and articles in electronic format (P < 0.001) as a source for their essays, but it did not influence the rate of plagiarism. Use of plagiarism detection software in evaluation of essays and consequent penalties had effectively deterred students from plagiarizing.     

What is specific to music processing? Insights from congenital amusia

Musical abilities are generally regarded as an evolutionary by-product of more important functions, such as those involved in language. However, there is increasing evidence that humans are born with musical predispositions that develop spontaneously into sophisticated knowledge bases and procedures that are unique to music. Recent findings also suggest that the brain is equipped with music-specific neural networks and that these can be selectively compromised by a congenital anomaly. This results in a disorder, congenital amusia, that appears to be limited to the processing of music. Recent evidence points to fine-grained perception of pitch as the root of musical handicap. Hence, musical abilities appear to depend crucially on the fine-tuning of pitch, in much the same way that language abilities rely on fine time resolution.
