The paper is concerned with the psychological relevance of a logical model for deductive reasoning. We propose a new way to analyze logical reasoning in a deductive version of the Mastermind game implemented within a popular Dutch online educational learning system (Math Garden). Our main goal is to derive predictions about the difficulty of Deductive Mastermind tasks. By means of a logical analysis we derive the number of steps needed for solving these tasks (a proxy for working (...) memory load). Our model is based on the analytic tableaux method, known from proof theory. We associate the difficulty of Deductive Mastermind game-items with the size of the corresponding logical trees obtained by the tableaux method. We derive empirical hypotheses from this model. A large group of students (over 37 thousand children, 5–12 years of age) played the Deductive Mastermind game, which gave empirical difficulty ratings of all 321 game-items. The results show that our logical approach predicts these item ratings well, which supports the psychological relevance of our model. (shrink)

Over the years a lot of easily computable strategies for the game mastermind have been proposed. One of the obvious strategies, guess that code that has the most possible answers, has been lacking. It is discussed in this paper.

I consider the natural infinitary variations of the games Wordle and Mastermind, as well as their game‐theoretic variations Absurdle and Madstermind, considering these games with infinitely long words and infinite color sequences and allowing transfinite game play. For each game, a secret codeword is hidden, which the codebreaker attempts to discover by making a series of guesses and receiving feedback as to their accuracy. In Wordle with words of any size from a finite alphabet of n (...) letters, including infinite words or even uncountable words, the codebreaker can nevertheless always win in n steps. Meanwhile, the mastermind number, defined as the smallest winning set of guesses in infinite Mastermind for sequences of length ω over a countable set of colors without duplication, is uncountable, but the exact value turns out to be independent of, for it is provably equal to the eventually different number, which is the same as the covering number of the meager ideal. I thus place all the various mastermind numbers, defined for the natural variations of the game, into the hierarchy of cardinal characteristics of the continuum. (shrink)

Two experiments examined the role of conditional reasoning in the logical deduction game, Mastermind . An analysis suggested that Modus Tollens (MT) reasoning could be used to determine the code structure, for example, in determining if any of the colours in the code are repeated. Consistent with this analysis, Experiment 1 showed that only MT errors are correlated with the number of hypotheses advanced in Mastermind . A subsequent analysis showed that conditional reasoning such as Affirming the (...) Consequent (AC) and Denying the Antecedent (DA) could lead to particularly damaging inferences only when the code was four different colours. When that was known before play, Experiment 2 showed that AC errors, but not MT errors, were significantly correlated with Mastermind hypotheses advanced. A stepwise multiple regression analysis supported these findings: When the solvers knew they were playing a four-colour code, there was a slight diminution in the variance explained by MT errors, and a significant increase in the variance explained by AC errors. An analysis of the number of different possible codes that could be consistent with hypotheses actually played showed that the number of such codes is far fewer when the code consists of four different colours than when its structure is not known. This analysis suggests that reasoners are therefore unlikely to discover many alternative causes for the feedback given when the code consists of four different colours, and it is under these conditions that humans are most likely to engage in AC reasoning.

Through a phenomenological study of horse-human relations, this article explores the ways in which, as embodied beings, we live relationally, rather than as separate human identities. Conceptually this challenges oppositional logic and humanist assumptions, but where poststructuralist treatments of these issues tend to remain abstract, this article is concerned with an embodied demonstration of the ways in which we experience a relational or in-between logic in our everyday lives.

We argue that pedagogic authority relies on love, which is misunderstood if seen as a matter of actions and subjects. Love is based not on finite subjects and objects existing in Euclidean space and linear time, but, rather, on the non-finite ontology, space and time of relations. Loving authority is a matter of calling and vocation, arising from the spontaneous and simultaneous call-and-response of a lively relation. We make this argument through a reading of Buber’s I–You relation and Murdoch’ s (...) account of the responsiveness of ascetic discipline. In presenting this analysis, we draw upon a case study from a research project on Australian teachers and students. (shrink)

Prior research suggests brokers do not always act in the best interests of clients, although morally obligated to do so. We empirically investigated this issue focusing on trades executed at best execution price, before and after the introduction of electronic limit-order trading, on the London Stock Exchange. As a result of limit-order trading, the proportion of trades executed at the best execution price for the customer significantly increased. We attribute this to a sustained increase in the liquidity of stocks as (...) a result of limit-order trading, regardless of market capitalisation. We discuss the ethical implications of our findings and conclude that market structures that enhance market competitiveness may help reconcile broker and client interests. (shrink)

This study examined the link between employees’ adult attachment orientations and perceptions of line managers’ interpersonal justice behaviors, and the moderating effect of national culture. Participants from countries categorized as low collectivistic and high collectivistic completed an online survey. Attachment anxiety and avoidance were negatively related to interpersonal justice perceptions. Cultural differences did not moderate the effects of avoidance. However, the relationship between attachment anxiety and interpersonal justice was non-significant in the Southern Asia cultural cluster. Our findings indicate the importance (...) of ‘fit’ between cultural relational values and individual attachment orientations in shaping interpersonal justice perceptions, and highlight the need for more non-western organizational justice research.

Abstract In this article we develop a relational understanding of sociality, that is, an account of social life that takes relation as primary. This stands in contrast to the common assumption that relations arise when subjects interact, an account that gives logical priority to separation. We will develop this relational understanding through a reading of the work of Martin Buber, a social philosopher primarily interested in dialogue, meeting, relationship, and the irreducibility and incomparability of reality. In particular, the article contrasts (...) Buber’s work with that of poststructuralist theorists who take as their starting point the deconstruction of the Hegelian logic of binary oppositions. Deconstruction understands difference as the excess that undoes the binary, but Buber, we argue, shows how difference derives from the primacy and ontological undefinability of relation. Relational logic does not exclude the logic of separations and oppositions: relation is the primal ground that makes separations possible.

The mechanisms responsible for the fine tuning of development, where the wildtype phenotype is reproduced with high fidelity, are not well understood. The difficulty in approaching this problem is the identification of mutant phenotypes indicative of a defect in these fine‐tuning control mechanisms. Evolutionary biologists have used asymmetry as a measure of developmental homeostasis. The rationale for this was that, since the same genome controls the development of the left and right sides of a bilaterally symmetrical organism, departures from symmetry (...) can be used to measure genetic or environmental perturbations. This paper examines the relationship between asymmtry and resistance to organophosphorous insecticides in the Australian sheep blowfly, Lucilia cuprina. A resistance gene, Rop‐1, which encodes a carboxylesterase enzyme, also confers a significant increase in asymmetry. Continued exposure of resistant populations to insecticide has selected a dominant suppressor of the asymmetry phenotype. Genetic evidence indicates that the modifier is the L. cuprina Notch homologue. (shrink)

Introduction: Another Diction The hack. The salesman. The fired cop. The drifter. The betrayed criminal. Each of these constitutes a novel literary invention; each gives a new sense to the investigative character. They are not modifications of the classical model, stamped with the rational imprimatur of Sherlock Holmes, C. Auguste Dupin, or Joseph Rouletabille – there is no line of filiation from these to Vachss’s Burke, Pelecanos’s Nick Stefanos, or Himes’s Coffin Ed Johnson and Grave Digger Jones. Even Lacan’s powerful (...) psychoanalytic reading of Poe’s “The Purloined Letter” reveals Dupin to be a genius only in a game whose dialectical structure is given in advance. Although the subjects that come to occupy this structure only acquire determination through the assumption of their places, the dynamic form of the dialectic is itself “foreclosed” by the phallus whose circulation organizes the system. Dupin understands the circulation of the signifier only because this circulation is the figure of the law. Rejecting the phallocentric rationality of the mastermind, the new figurations of Vachss, Pelecanos, Himes, and others retain only in order to parody the grand orchestration of reason – their language is slang not deduction. They are not detectives but “dicks”: a name that incorporates within its reduction an empirical transformation of the transcendental. In fact, it is a transformation of the very sense of inquiry that requires this new type of conceptual personae in order to traverse its contours. The philosophical project of Gilles Deleuze – which he characterizes as a “transcendental empiricism” – is directed toward freeing thought from its determination by the philosophical traditions that constitute its history. Such a freeing would allow for a philosophical conceptualization of present events that are no longer able to be adequately conceptualized by that history. The distinctive character of Deleuze’s project comes from his insistence on the discontinuity between the tradition of thought and the new formulations that it is called upon to generate. For Deleuze, the philosopher is the one who asks about the generation of new concepts and thereby places herself in a double bind. On the one hand, the philosopher is historically conditioned, thrown into a tradition whose tools present a limited number of possible conceptual resolutions of a particular event. On the other hand, this conditional determination of philosophical thought is repeated, perpetually, so that the philosopher is always a parody of herself: solving the question of the determination of a present event by resolving the question of the determinability of the present by the past. This situation of parody is the limit of thinking; it is where thinking develops according to the vicissitudes of history. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:After the Future. The Paradoxes of Postmodernism and Contemporary Russian CultureDmitry KhaninAfter the Future. The Paradoxes of Postmodernism and Contemporary Russian Culture, by Mikhail Epstein; translated with an introduction by Anessa Miller-Pogacar; xvi & 394 pp. Amherst: University of Massachusetts Press, 1995, $55.00 cloth, $19.95 paper.Mikhail Epstein, a renowned Soviet critic—his books in Russian include Paradoxes of the New (1988) and Faith and Image: The Religious Subconscious in (...) [End Page 508] Twentieth Century Russian Culture (1994)—emigrated to the U.S. in 1988. After the Future is the first collection of his major essays (written from 1986 to 1991) in English translation. It begins with the article “New Currents in Russian Poetry: Conceptualism, Metarealism, and Presentism,” which first introduced to the Soviet reader a group of postmodernist poets, just coming out (with the advent of glasnost) from the literary underground. Other articles (“Avant-Garde Art and Religion,” “After the Future: On the New Consciousness in Literature”), though first published in Russian literary journals, were shipped to Russia from “the other shore” (to use Alexander Herzen’s description of emigre writers’ whereabouts vis-à-vis their homeland). The latest studies (“Relativistic Patterns in Totalitarian Thinking: The Linguistic Games of Soviet Ideology,” “The Origins and Meaning of Russian Postmodernism”) were not only sent from the other shore but apparently produced for the other shore. Instead of analyzing the recent Russian literary crop and emerging aesthetic sensibilities, Epstein focuses on Russian historic experience in its entirety, which he somewhat didactically clarifies for the foreign reader.Despite its shifting perspectives, After the Future features a distinctive approach toward Russian postmodernism, its bona fide subject matter. Following Jean Baudrillard, Epstein defines postmodernism as simulation (“the production of reality as a series of plausible copies”) that engenders some new hyperreality and in so doing supplants “reality itself, which then becomes irrecoverable” (p. 189). The originality of Epstein’s position lies, however, in his claim that Russia as a historic and cultural entity is a postmodernist phenomenon in its own right that simulates and masterminds reality. Epstein’s claim that postmodernism is ingrained in Russian tradition is pitted specifically against those who doubt that Russia is ready to enjoy its own postmodernist bash since (contrary to the West) it never went through prior modernist phases. To prove that Russia foreshadowed postmodernism, Epstein draws on a number of historic illustrations. He cites the forceful adoption of Christianity under Prince Vladimir in 988, Peter the Great’s building of Petersburg in the “Finnish swamp” and Prince Potemkin’s infamous make-up villages as examples of the Russian tendency to forfeit the status quo for the sake of trumped-up, ersatz realities.However, Epstein’s arguments to the effect that Russia, and not the West, is the birthplace of postmodernism are not very convincing since (in accordance with his own premise) other countries can claim such a dubious distinction as well. (“Russia is the motherland of elephants”—the Russians joke about claims by zealous patriots that all great discoveries were known in their country before they appeared elsewhere.) Elsewhere, the building of the Chinese wall and the ensuing Chinese policies of isolationism, draconian enclosures of peasant land in England that led to a speedy transition to capitalism, drastic economic and social reforms after the French Revolution, and the racist policies of the Third Reich were just as arbitrary, and yet transformative of prior realities, as any of [End Page 509] Russia’s most foolhardy experiments. Ironically, Epstein’s claim that Russia is the motherland of postmodernism harks back to the turn-of-the-century controversy as to whether it is pertinent to apply Marxist theory to rustic Russia. Lenin argued that Russia can claim Marxism as its own because all of its long-suffering history was an anticipation of Marxism and leading toward it. Epstein analogously contends that there is a special, indigenous Russian route to postmodernism, a statement that evokes similar pronouncements ingrained in Russian philosophical tradition: Epstein’s thesis that Russia is “irreal” reminds one of Peter Chaadaev’s contention that Russia does not have a history; his idea that Russia is on the threshold of a cultural synthesis with the...

No fictional character is more renowned for his powers of thought and observation than Sherlock Holmes. But is his extraordinary intellect merely a gift of fiction, or can we learn to cultivate these abilities ourselves, to improve our lives at work and at home? We can, says psychologist and journalist Maria Konnikova, and in Mastermind she shows us how. Beginning with the "brain attic"--Holmes's metaphor for how we store information and organize knowledge--Konnikova unpacks the mental strategies that lead to (...) clearer thinking and deeper insights. Drawing on twenty-first-century neuroscience and psychology, Mastermind explores Holmes's unique methods of ever-present mindfulness, astute observation, and logical deduction. In doing so, it shows how each of us, with some self-awareness and a little practice, can employ these same methods to sharpen our perceptions, solve difficult problems, and enhance our creative powers. For Holmes aficionados and casual readers alike, Konnikova reveals how the world's most keen-eyed detective can serve as an unparalleled guide to upgrading the mind. (shrink)

Games occupy a unique and valuable place in our lives. Game designers do not simply create worlds; they design temporary selves. Game designers set what our motivations are in the game and what our abilities will be. Thus: games are the art form of agency. By working in the artistic medium of agency, games can offer a distinctive aesthetic value. They support aesthetic experiences of deciding and doing. -/- And the fact that we play games shows something (...) remarkable about us. Our agency is more fluid than we might have thought. In playing a game, we take on temporary ends; we submerge ourselves temporarily in an alternate agency. Games turn out to be a vessel for communicating different modes of agency, for writing them down and storing them. Games create an archive of agencies. And playing games is how we familiarize ourselves with different modes of agency, which helps us develop our capacity to fluidly change our own style of agency. (shrink)

Games may seem like a waste of time, where we struggle under artificial rules for arbitrary goals. The author suggests that the rules and goals of games are not arbitrary at all. They are a way of specifying particular modes of agency. This is what make games a distinctive art form. Game designers designate goals and abilities for the player; they shape the agential skeleton which the player will inhabit during the game. Game designers work in the (...) medium of agency. Game-playing, then, illuminates a distinctive human capacity. We can take on ends temporarily for the sake of the experience of pursuing them. Game play shows that our agency is significantly more modular and more fluid than we might have thought. It also demonstrates our capacity to take on an inverted motivational structure. Sometimes we can take on an end for the sake of the activity of pursuing that end. (shrink)

While video games have blossomed into the foremost expression of contemporary popular culture over the past decades, their critical study occupies a fringe position in American Studies. In its engagement with video games, this book contributes to their study but with a thematic focus on a particularly important subject matter in American Studies: spatiality. The volume explores the production, representation, and experience of places in video games from the perspective of American Studies. Contributions critically interrogate the use of spatial myths (...) ("wilderness," "frontier," or "city upon a hill"), explore games as digital borderlands and contact zones, and offer novel approaches to geographical literacy. Eventually, Playing the Field II brings the rich theoretical repertoire of the study of space in American Studies into conversation with questions about the production, representation, and experience of space in video games.

Critical Gaming: Interactive History and Virtual Heritage can be seen as a collection of chapters designed to provoke thought and discussion, or it can be seen and used as separate chapters that may help class debate in courses dealing with the digital humanities, game studies (especially in the areas of serious games and game-based learning) or aspects of virtual heritage.

Game theory is a branch of mathematics that studies strategic interactions, i.e., interactions which involve more than one agent and in which each agent makes her/his decision while striving to predict the decisions of other agents. Game theory has been successfully applied in many areas of both the natural and social sciences, and it is the belief of this book's author that it can also be gainfully invoked in the area of legal philosophy. In this book, Wojciech Zaluski (...) analyzes legal-philosophical concepts - such as legal interpretation, justice, legal rights, contract law, tort law, and property law - through the lens of game theory. The book appeals mainly to game theory's conceptual rather than the technical side, and intertwines game-theoretical analysis with the philosophical. It will be accessible to a wider circle of readers interested in legal and moral philosophy. (shrink)

Metagames: Games About Games scrutinizes how various meta devices, such as breaking the fourth wall and unreliable narrator, change and adapt when translated into the uniquely interactive medium of digital games. Through its theoretical analyses and case studies, the book shows how metafictional experimentation can be used to both challenge and push the boundaries of what a game is and what a player's role is in play, and to raise more profound topics such as those describing experiences of people (...) of oppressed identities. The book is divided into six chapters that deal with the following meta devices: breaking the fourth wall, Hypermediation, unreliable narrator, abusive game design, fragmentation, and parody. The book will predominantly interest scholars and students of media studies and game studies as it continues discourses held in the discipline regarding the metareferential character of digital games.

Toward the end of Light in August, in the climactic scene in Chapter 1 where the authorities of justice pursue the elusive Joe Christmas through the streets of Jefferson, William Faulkner introduces a new character, Percy Grimm, a twenty-five-year-old captain in the State National Guard who has relentlessly acquired the rank of a special deputy for the search. As the town closes for the weekend, Grimm keeps vigil at a downtown store where other townsfolk have begun a poker game (...) to stay awake through the night as the search goes on. In their zeal to uphold law and justice, his men revel in their fantastic make-believe that they are doing the work of “a hidden and unsleeping and omnipotent eye watching the doings of men.” The poker game goes on through Saturday night until Christmas is spotted and given chase. As Grimm runs through the streets after the fleeing man, Faulkner presents to us the deputy's stream of thought from an omniscient point of view: “There was nothing vengeful about him either, no fury, no outrage. He was moving again almost before he had stopped, with that lean, swift, blind obedience to whatever Player moved him on the Board” (437). Through the rest of the chapter, Grimm, who has not participated in the poker game at all, thinks and acts as if he is engaged in a chess game, not as a player but as the stake or the pawn in a board game in which Jefferson is the board on which he and Christmas are being moved from place to place by two larger forces, he by the benevolent Providence and Christmas by the powers opposed to God. Finally, when Christmas is cornered and fatally shot in Reverend Hightower's kitchen, this fantasized game seems to end. (shrink)

Innovative understanding or explanation stems almost exclusively from analogical reasoning. Induction systematizes the familiar; deduction casts it into formal relationship. Reasoning by analogy brings to bear on the familiar a new perspective derived from another realm of inquiry. Models are fruits from the tree of analogical knowledge.

In this article, we try to trace the relationship between semiotics and theory of legal reasoning using Peirce’s idea that all reasoning must be necessarily in signs: every act of reasoning/argumentation is a sign process, leading to “the growth of knowledge. The broad scope and universal character of Peirce’s sign theory of reasoning allows us to look for new conciliatory paradigms, which must be presented in terms of possible synthesis between the traditional approaches to argumentation. These traditional approaches are strongly (...) affected by either the dialectical (logical) perspective or the rhetorical perspective on argumentation, while Peirce’s approach tends to reconcile the rhetorical and methodological aspects of reasoning. This reconcilation is best illustrated by Peircean analysis of argument’s logical and rhetorical structure; while the diagrammatic (iconic) analysis of arguments is performed in the system of Existential Graphs (which is Peirce’s major methodological system, designed for the expressions of propositions in point of their relational structure). Obviously, Peirce’s original division of argument parts offered only the characterisation of the sign activity (involved in the process of reasoning), and thus left much to be desired in terms of practical explication.

Using Bernard Suits’s brilliant analysis (contra Wittgenstein) of playing a game, this paper examines the intrinsic value of game-playing. It argues that two elements in Suits’s analysis make success in games difficult, which is one ground of value, while a third involves choosing a good activity for the property that makes it good, which is a further ground. The paper concludes by arguing that game-playing is the paradigm modern (Marx, Nietzsche) as against classical (Aristotle) value: since its (...) goal is intrinsically trivial, its value is entirely one of process rather than product, journey rather than destination.

We first prove the equivalence between σ-projective determinacy and the determinacy of certain classes of games of variable length <ω^2 (Theorem 2.4). We then give an elementary proof of the determinacy of σ-projective sets from optimal large-cardinal hypotheses (Theorem 4.4).

Is it ever morally wrong to enjoy fantasizing about immoral things? Many video games allow players to commit numerous violent and immoral acts. But, should players worry about the morality of their virtual actions? A common argument is that games offer merely the virtual representation of violence. No one is actually harmed by committing a violent act in a game. So, it cannot be morally wrong to perform such acts. While this is an intuitive argument, it does not resolve (...) the issue. -/- Focusing on why individual players are motivated to entertain immoral and violent fantasies, Video Games, Violence, and the Ethics of Fantasy advances debates about the ethical criticism of art, not only by shining light on the interesting and under-examined case of virtual fantasies, but also by its novel application of a virtue ethical account. Video games are works of fiction that enable players to entertain a fantasy. So, a full understanding of the ethical criticism of video games must focus attention on why individual players are motivated to entertain immoral and violent fantasies. -/- Video Games, Violence, and the Ethics of Fantasy engages with debates and critical discussions of games in both the popular media and recent work in philosophy, psychology, media studies, and game studies.

Situational Design lays out a new methodology for designing and critiquing videogames. While most game design books focus on games as formal systems, Situational Design concentrates squarely on player experience.

Many weaknesses of game theory are cured by new models that embody simple cognitive principles, while maintaining the formalism and generality that makes game theory useful. Social preference models can generate team reasoning by combining reciprocation and correlated equilibrium. Models of limited iterated thinking explain data better than equilibrium models do; and they self-repair problems of implausibility and multiplicity of equilibria.

This article explores the nature and theoretical import of a hitherto neglected class of fictions which we term ‘self-involving interactive fictions’. SIIFs are interactive fictions, but they differ from standard examples of interactive fictions by being, in some important sense, about those who consume them. In order to better understand the nature of SIIFs, and the ways in which they differ from other fictions, we focus primarily on the most prominent example of the category: video-game fictions. We argue that (...) appreciating the self-involving nature of video-game fictions is key to understanding various otherwise puzzling phenomena concerning the ways in which consumers respond to them. Video-game fictions are, however, far from being the only extant example of this class; and we suggest that the recent philosophical interest in video games would be better focused on the wider class of self-involving interactive fictions.

This volume contains papers presented at the Poznań Reasoning Week multi-conference held in Poznań in September 11-15, 2018. PRW aims at bringing together experts whose research offers a broad range of perspectives on systematic analyses of reasoning processes and their formal modelling. The 2018 edition consisted of three conferences, which addressed the following topics: (i) games in reasoning research, (ii) the interplay of logic and cognition, and (iii) refutation systems. The papers collected in this volume address all these topics.

Game theory involves deliberating about what to do in light of what other people are likely to do. One of the central frameworks of game theory is the prisoner’s dilemma, in which participants who make rational choices end up in suboptimal outcomes. Using the prisoner’s dilemma to model competition between firms sets the stage for a new and promising approach to business ethics: the market failures approach.

In The Expanse, the major powers do a great deal of talking, but don't have a great deal of understanding. Discussing language can be surprisingly difficult, because the only way to discuss language is with language and that peculiar arrangement can lead to some outright strangeness. Eccentric, reclusive, and hot‐tempered, Ludwig Wittgenstein is a key philosopher in the examination of language and meaning. Wittgenstein's philosophical studies centered around how to express meaning and why conveying meaning so often breaks down. In (...) Wittgenstein's earlier writings he articulates the picture book model of language. Language can be written, spoken, signed, and so forth, but it is convention to refer to any language user as a ‘speaker.’ Wittgenstein argues that language works much like a game, relying on contextual rules and actions to guide and form meaning. The language game model of language also better explains why Belters and the Inners seem doomed to fail to communicate. (shrink)
