We introduce a reciprocity criterion for coalition formation among goal-directed agents, which we call the indecomposable do-ut-des property. It refines an older reciprocity property, called the do-ut-des or give-to-get property by considering the fact that agents prefer to form coalitions whose components cannot be formed independently. A formal description of this property is provided as well as an analysis of algorithms and their complexity. We provide an algorithm to decide whether a coalition has the desired property, and we show that (...) the problem to verify whether a single coalition satisfies the property is tractable. Moreover, we provide an algorithm to search all the sub-coalitions of a given coalition satisfying the new property. Even if this problem is not computationally tractable, we show that in several cases, also the complexity of this problem may decrease considerably. (shrink)

Driving behaviours and fitness to drive have been assessed using different tools over time: standardized neuropsychological, on-road and driving simulation testing. Nowadays, the great variability of topics related to driving simulation has elicited a high number of reviews. The present work aims to perform a scientometric analysis on driving simulation reviews and to propose a selective review of reviews focusing on critical issues related to validity and fidelity. A scientometric analysis of driving simulation reviews published from 1988 to 2019 was (...) conducted. Bibliographic data from 298 reviews were extracted from Scopus and WoS. Performance analysis was conducted to investigate most prolific Countries, Journals, Institutes and Authors. A cluster analysis on authors’ keywords was performed to identify relevant associations between different research topics. Based on reviews extracted from cluster analysis, a selective review of reviews was conducted to answer questions regarding validity, fidelity and critical issues. USA and Germany are the first two Countries for number of driving simulation reviews. USA is the leading Country with 5 Institutes in the top-ten. Top Authors wrote from 3 to 7 reviews each and belong to Institutes located in North America and Europe. Cluster analysis identified three clusters and eight keywords. The selective review of reviews showed a substantial agreement for supporting validity of driving simulation with respect to neuropsychological and on-road testing, while for fidelity with respect to real-world driving experience a blurred representation emerged. The most relevant critical issues were the a) lack of a common set of standards, b) phenomenon of simulation sickness, c) need for psychometric properties, lack of studies investigating d) predictive validity with respect to collision rates and e) ecological validity. Driving simulation represent a cross-cutting topic in scientific literature on driving, and there are several evidences for considering it as a valid alternative to neuropsychological and on-road testing. Further research efforts could be aimed at establishing a consensus statement for protocols assessing fitness to drive, in order to a) use standardized systems, b) compare systematically driving simulators with regard to their validity and fidelity, and c) employ shared criteria for conducting studies in a given sub-topic.

Using a large sample of retail investors as well as experimental data we find that risk and ambiguity aversion are positively correlated. We provide evidence that a common link is decision mode: intuitive thinkers tolerate more risk and ambiguity than effortful reasoners. One interpretation is that intuitive thinking confers an advantage in risky or ambiguous situations. We present supporting lab and field evidence that intuitive thinkers outperform others in uncertain environments. Finally, we find that risk and ambiguity aversion vary with (...) individual characteristics and wealth. The wealthy are less risk averse but more ambiguity averse, which has implications for financial puzzles. (shrink)

The essay is dedicated to war considered through the reflections of Roger Caillois and in particular through certain motifs – feast, sacred, vertigo – that allow us to grasp its ‘metaphysical’ intention, i.e. capable of looking at war as the point of chiasmatic reversibility of life and death.

Hands are commonly held up as an exemplar of well-known, familiar objects. However, conceptual knowledge of the hand has been found to show highly stereotyped distortions. Specifically, people judge their knuckles as farther forward in the hand than they actually are. The cause of this distal bias remains unclear. In Experiment 1, we tested whether both visual and tactile information contribute to the distortion. Participants judged the location of their knuckles by pointing to the location on their palm directly opposite (...) each knuckle with: 1) a metal baton (using vision and touch) 2) a metal baton while blindfolded (using touch), 3) a laser pointer (using vision). In Experiment 2, we investigated whether judgments are influenced by visual landmarks such as the creases at the base of each finger on the palm. Participants localized their knuckles on either a photograph or a silhouette of their hand. In both experiments, clear distortions were found across conditions, of generally similar magnitude. These results show that distal bias is resistant to changes in the stimulus information and does not rely on any specific stimulus cue or single sensory modality, suggesting that such mislocalisations reflect a conceptual misrepresentation of hand structure.

_Abstract_: In this introduction to the thematic issue on _the future of the cognitive science(s)_, we examine how challenges and uncertainties surrounding the past and present of this discipline make it difficult to chart its future. We focus on two main questions. The first is whether cognitive science is a single unified field or inherently pluralistic. This question can be asked at various levels: First, with respect to the disciplines that should be included in the cognitive hexagon and their reciprocal (...) relationships: should we speak of cognitive science or of the cognitive sciences? Second, with regard to the conceptual and methodological changes (turns or revolutions) that have taken place within the cognitive project from its inception to the present day. Third, it pertains to cognitive psychology as a discipline. Before the emergence of cognitive science psychology was a fragmented discipline characterized by different traditions and approaches: has cognitive science been able to stem this fragmentation? Finally, we can question the unity of the cognitive architecture itself: is cognition produced by homogeneous or heterogenous mechanisms for information processing? We show that the issue of unity is addressed by several of the papers included in this thematic issue. In the second part of this introduction, we query the role that each component discipline should play in the cognitive project and in particular which should lead the project going forward, and why. Again, we show how this issue has been tackled by several articles featured in this collection. _Keywords_: Future of Cognitive Science; Cognitive Psychology; Pluralism and Cognitive Science; Philosophy and Cognitive Science; Fragmentation of Psychology _Quale futuro per la scienza cognitiva?_ _Riassunto_: In questa introduzione al fascicolo tematico dedicato al _futuro della scienza cognitiva_ prendiamo in considerazione sfide e incertezze che caratterizzano il passato e il presente di questa disciplina, rendendo difficile prevedere il suo futuro. Due le questioni principali su cui concentriamo l’attenzione. La prima: la scienza cognitiva è un ambito unitario o intrinsecamente pluralistico? Questo problema si manifesta a diversi livelli. In primo luogo, riguarda le discipline che dovrebbero comporre l’esagono cognitivo e le loro relazioni reciproche: dovremmo parlare di scienza cognitiva o di scienze cognitive? In secondo luogo, riguarda le trasformazioni (svolte o rivoluzioni) concettuali e metodologiche avvenute all’interno di questo progetto dalla sua nascita fino ai giorni nostri. In terzo luogo, riguarda la psicologia cognitiva. Prima della nascita della scienza cognitiva la psicologia era una disciplina frammentaria caratterizzata da diverse tradizioni e approcci: possiamo dire che la scienza cognitiva abbia posto rimedio a tale frammentazione? Infine, il problema dell’unità sorge anche in relazione all’architettura cognitiva stessa, considerando che la cognizione potrebbe o potrebbe non essere prodotta da meccanismi omogenei di elaborazione delle informazioni. Nella presentazione che segue si cerca di mostrare come l’unità, in tutte queste varianti, sia una questione affrontata da diversi articoli presenti in questo fascicolo tematico. Nella seconda parte di questa introduzione prendiamo in considerazione il problema del ruolo che ciascuna disciplina componente dovrebbe svolgere nel progetto cognitivo e, in particolare, quale dovrebbe guidare il progetto e perché, ponendo in evidenza come anche questa sia una questione centrale, tematizzata da diversi lavori presentati in questo fascicolo. _Parole chiave_: Futuro della scienza cognitiva; Psicologia cognitiva; Pluralismo e scienza cognitiva; Filosofia e scienza cognitiva; Frammentazione della psicologia.

"Both superb and essential... Succi, with clarity and wit, takes us from quarks and Boltzmann to soft matter - precisely the frontier of physics and life." Stuart Kauffman, MacArthur Fellow, Fellow of the Royal Society of Canada, Gold Medal Accademia Lincea We live in a world of utmost complexity, outside and within us. There are thousand of billions of billions of stars out there in the Universe, a hundred times more molecules in a glass of water, and another hundred times (...) more in our body, all working in sync to keep us alive and well. At face value, such numbers spell certain doom for our ability to make any sense at all of the world around and within us. And yet, they don't. Why, and how - this book endeavours to provide an answer to these questions with specific reference to a selected window of the physics-biology interface. The story unfolds over four main Parts. Part I provides an introduction to the main organizational principles which govern the functioning of complex systems in general, such as nonlinearity, nonlocality and ultra-dimensions. Part II deals with thermodynamics, the science of change, starting with its historical foundations laid down in the 19th century, and then moving on to its modern and still open developments in connection with biology and cosmology. Part III deals with the main character of this book, free energy, and the wondrous scenarios opened up by its merger with the modern tools of statistical physics. It also describes the basic facts about soft matter, the state of matter most relevant to biological organisms. Finally, Part IV discusses the connection between time and complexity, and its profound implications on the human condition, i.e. the one-sided nature of time and the awareness of human mortality. It concludes with a few personal considerations about the special place of emotions and humility in science. (shrink)

The relentless exploitation of the earth's resources and technologys boundless growth are a matter of urgent concern. When did this race towards the limitless begin? The Greeks, who shaped the basis of Western thinking, lived in mortal fear of humanity's hidden hunger for the infinite and referred to it as hubris, the one true sin in their moral code. Whoever desired or possessed too much was implacably punished by nemesis, yet the Greeks themselves were to pioneer an unprecedented level of (...) ambition that began to reverse that tabu. If it is true that no culture can truly repudiate its origins, and that gods who are no longer potent can vanish but still leave behind a body of myth which coninues to live and assert itself in modernized garb, then our concern with the limits of growth reflects something more than an awareness of new technological problems - it also brings to light a psychic wound a a feeling of guilt which are infinitely more ancient.

Simple assumptions represent a decisive reason to prefer one theory to another in everyday scientific praxis. But this praxis has little philosophical justification, since there exist many notions of simplicity, and those that can be defined precisely strongly depend on the language in which the theory is formulated. The language dependence is a natural feature—to some extent—but it is also believed to be a fatal problem, because, according to a common general argument, the simplicity of a theory is always trivial (...) in a suitably chosen language. But, this trivialization argument is typically either applied to toy-models of scientific theories or applied with little regard for the empirical content of the theory. This paper shows that the trivialization argument fails, when one considers realistic theories and requires their empirical content to be preserved . In fact, the concepts that enable a very simple formulation, are not necessarily measurable, in general. Moreover, the inspection of a theory describing a chaotic billiard shows that precisely those concepts that naturally make the theory extremely simple are provably not measurable. This suggests that—whenever a theory possesses sufficiently complex consequences—the constraint of measurability prevents too simple formulations in any language. This explains why the scientists often regard their assessments of simplicity as largely unambiguous. In order to reveal a cultural bias in the scientists’ assessment, one should explicitly identify different characterizations of simplicity of the assumptions that lead to different theory selections. General arguments are not sufficient. (shrink)

Luigi Giussani, a high school religion teacher throughout the 1950s and 1960s, grounded his teachings in the vast body of experience to be found in Christianity's two-thousand-year history. He told his students, “I'm not here to make you adopt the ideas I will give you as your own, but to teach you a method for judging the things I will say.” Throughout his life, education was one of Giussani's primary intellectual interests. He believed that effective education required an adequate (...) background in the Christian tradition, presented within a lived experience that underscored the capacity of the faith to answer universal questions. What he proposed was a process that allowed one to sift through tradition, critically examining it and comparing it against the ultimate criteria for judgment: the desires of the heart. In Giussani's view, the primary concern was to “educate the human heart as God made it.” In The Risk of Education he states that fear leads students to associate this process of criticism with negativity or doubt. Yet, without an education in criticism, students cannot develop conviction. At a time when young people are abandoning the church and questioning the value of faith, Giussani's method of judging and verifying Christianity as an experience seems a necessary intervention. In The Risk of Education he argues that, ultimately, education and the Christian message reveal themselves through human freedom. (shrink)
