We define a tableau calculus for the logic of only knowing and knowing at most ON, which is an extension of Levesque's logic of only knowing O. The method is based on the possible-world semantics of the logic ON, and can be considered as an extension of known tableau calculi for modal logic K45. From the technical viewpoint, the main features of such an extension are the explicit representation of "unreachable" worlds in the tableau, and an additional branch closure condition (...) implementing the property that each world must be either reachable or unreachable. The calculus allows for establishing the computational complexity of reasoning about only knowing and knowing at most. Moreover, we prove that the method matches the worst-case complexity lower bound of the satisfiability problem for both ON and O. With respect to [22], in which the tableau calculus was originally presented, in this paper we both provide a formal proof of soundness and completeness of the calculus, and prove the complexity results for the logic ON.

We study the problem of embedding Halpern and Moses's modal logic of minimal knowledge states into two families of modal formalism for nonmonotonic reasoning, McDermott and Doyle's nonmonotonic modal logics and ground nonmonotonic modal logics. First, we prove that Halpern and Moses's logic can be embedded into all ground logics; moreover, the translation employed allows for establishing a lower bound (3p) for the problem of skeptical reasoning in all ground logics. Then, we show a translation of Halpern and Moses's logic (...) into a significant subset of McDermott and Doyle's formalisms. Such a translation both indicates the ability of Halpern and Moses's logic of expressing minimal knowledge states in a more compact way than McDermott and Doyle's logics, and allows for a comparison of the epistemological properties of such nonmonotonic modal formalisms.

Proponents of numerous recent theories of a person's good hold that a plausible account of the good for a person must satisfy existence internalism. Yet little direct defense has been given for this position. I argue that the principal intuition behind internalism supports a stronger version of the thesis than it might appear--one that effects a "double link" to motivation. I then identify and develop the main arguments that have been or might be given in support of internalism about a (...) person's good, showing how these arguments support this stronger version of internalism.

In our everyday lives, we confront a host of moral issues. Once we have deliberated and formed judgments about what is right or wrong, good or bad, these judgments tend to have a marked hold on us. Although in the end, we do not always behave as we think we ought, our moral judgments typically motivate us, at least to some degree, to act in accordance with them. When philosophers talk about moral motivation, this is the basic phenomenon they seek (...) to understand. Moral motivation is an instance of a more general phenomenon—what we might call normative motivation—for our other normative judgments also typically have some motivating force. When we make the normative judgment that something is good for us, or that we have a reason to act in a particular way, or that a specific course of action is the rational course, we also tend to be moved. Many philosophers have regarded the motivating force of normative judgments as the key feature that marks them as normative, thereby distinguishing them from the many other judgments we make. In contrast to our normative judgments, our mathematical and empirical judgments, for example, seem to have no intrinsic connection to motivation and action. The belief that an antibiotic will cure a specific infection may move an individual to take the antibiotic, if she also believes that she has the infection, and if she either desires to be cured or judges that she ought to treat the infection for her own good. All on its own, however, an empirical belief like this one appears to carry with it no particular motivational impact; a person can judge that an antibiotic will most effectively cure a specific infection without being moved one way or another.

Taking for granted a radical criticism of the universalistic value of a post-Protestant understanding of religion and of the nexus between political democracy and secularization, the article aims first at framing the perspective of multicultural jurisdictions within contemporary processes of change of religious pluralism on a transnational scale; secondly at framing that perspective within the intellectual tradition of legal pluralism; and finally at inquiring into the compatibility of the new conceptual constellation ‘post-secular society plus legal pluralism’ with a liberal frame.
The widespread use of brain imaging techniques encourages conceiving of neuroscience as the forthcoming “mindscience.” Perhaps surprisingly for many, this conclusion is still largely unwarranted. The present paper surveys various shortcomings of neuroscience as a putative “mindscience.” The analysis shows that the scope of mind (both cognitive and phenomenal) falls outside that of neuroscience. Of course, such a conclusion does not endorse any metaphysical or antiscientific stance as to the nature of the mind. Rather, it challenges a series of assumptions (...) that the undeniable success of neuroscience has fostered. In fact, physicalism is here taken as the only viable ontological framework – an assumption that does not imply that the central nervous system exhausts the physical domain. (shrink)
Foucault come educatore non dirige da un luogo esterno verso di noi un insegnamento, una dottrina, piuttosto sente la responsabilità di cercare e di estrarre dal mondo «qualcosa» che possa animare l’esperienza che si fa del mondo, di mostrare da una prospettiva latente l’esperienza già fatta, come una scheggia di «reale» che nel mondo si manifesta. Foucault può essere un educatore se accettiamo che la verità è sempre ancora da fare, concretamente, che siamo sempre corresponsabili della verità che è in (...) gioco nella nostra formazione. Può essere educatore, infatti, solo chi è disposto non tanto a «comprendere prima», ma a comprendere nuovamente ogni volta, ogni volta che si dà un’occasione formativa e a profanare eventualmente l’attualità e la solidità di quel che si sa nella condivisione del rischio e della libertà che ogni pratica di ricerca comporta.

The aim of the paper is to critically assess the idea that reasons for action are provided by desires (the Model). I start from the claim that the most often employed meta-ethical background for the Model is ethical naturalism; I then argue against the Model through its naturalist background. For the latter purpose I make use of two objections that are both intended to refute naturalism per se. One is G. E. Moore’s Open Question Argument (OQA), the other is Derek (...) Parfit’s Triviality Objection (TO). I show that naturalists might be able to avoid both objections in case they can vindicate the reduction proposed. This, however, leads to further conditions whose fulfillment is necessary for the success of vindication. I deal with one such condition, which I borrow from Peter Railton and Mark Schroeder: the demand that naturalist reductions must be tolerably revisionist. In the remainder of the paper I argue that the most influential versions of the Model are intolerably revisionist. The first problem concerns the picture of reasons many recent formulations of the Model advocate. By using an objection from Michael Bedke I show that on this interpretation obvious reasons won’t be accounted for by the Model. The second problem concerns idealization that is also often part of the Model. Invoking an argument by Connie Rosati, I show that the best form of idealization, the ideal advisor account, is inadequate. Hence, though not knock down arguments as they were intended to be, OQA and TO do pose a serious threat to the Model. (shrink)
Internalism about a person's good is roughly the view that in order for something to intrinsically enhance a person's well-being, that person must be capable of caring about that thing. I argue in this paper that internalism about a person's good should not be believed. Though many philosophers accept the view, Connie Rosati provides the most comprehensive case in favor of it. Her defense of the view consists mainly in offering five independent arguments to think that at least some (...) form of internalism about one's good is true. But I argue that, on closer inspection, not one of these arguments succeeds. The problems don't end there, however. While Rosati offers good reasons to think that what she calls 'two-tier internalism' would be the best way to formulate the intuition behind internalism about one's good, I argue that two-tier internalism is actually false. In particular, the problem is that no substantive theory of well-being is consistent with two-tier internalism. Accordingly, there is reason to think that even the best version of internalism about one's good is in fact false. Thus, I conclude, the prospects for internalism about a person's good do not look promising. (shrink)
The paper provides some introductory comments and a preliminary translation of Avicenna’s Burhān, IV, 2. I shall first set the stage by outlining the structure of the book (sec. 1). I will then briefly introduce (sec. 2) a number of notions that are dealt with in the first treatise of the Burhān (e.g. definition, description). Burhān, IV, 2 is split into two parts: the first focuses mainly on Aristotle’s An. Post., B, 4, whereas the second covers some of the topics (...) of B, 5 and B, 6. Accordingly, sec. 3 will be devoted to a cursory presentation of Aristotle’s arguments in An. Post., B, 4 along with a more detailed discussion of its Avicennan counterpart, focusing on the indemonstrability of definition; sec. 4, finally, will be a presentation of the second part of the chapter, concerning the relationship between definition and division. An English translation of the entire chapter is appended to the paper and is accompanied by some notes. (shrink)
While the recent special issue of JCS on machine consciousness (Volume 14, Issue 7) was in preparation, a collection of papers on the same topic, entitled Artificial Consciousness and edited by Antonio Chella and Riccardo Manzotti, was published. 1 The editors of the JCS special issue, Ron Chrisley, Robert Clowes and Steve Torrance, thought it would be a timely and productive move to have authors of papers in their collection review the papers in the Chella and Manzotti book, and (...) include these reviews in the special issue of the journal. Eight of the JCS authors (plus Uziel Awret) volunteered to review one or more of the fifteen papers in Artificial Consciousness; these individual reviews were then collected together with a minimal amount of editing to produce a seamless chapter-by-chapter review of the entire book. Because the number and length of contributions to the JCS issue was greater than expected, the collective review of Artificial Con- sciousness had to be omitted, but here at last it is. Each paper’s review is written by a single author, so any comments made may not reflect the opinions of all nine of the joint authors! (shrink)
This paper offers an analysis of a hitherto neglected text on insoluble propositions dating from the late XiVth century and puts it into perspective within the context of the contemporary debate concerning semantic paradoxes. The author of the text is the italian logician Peter of Mantua (d. 1399/1400). The treatise is relevant both from a theoretical and from a historical standpoint. By appealing to a distinction between two senses in which propositions are said to be true, it offers an unusual (...) solution to the paradox, but in a traditional spirit that contrasts a number of trends prevailing in the XiVth century. It also counts as a remarkable piece of evidence for the reconstruction of the reception of English logic in italy, as it is inspired by the views of John Wyclif. Three approaches addressing the Liar paradox (Albert of Saxony, William Heytesbury and a version of strong restrictionism) are first criticised by Peter of Mantua, before he presents his own alternative solution. The latter seems to have a prima facie intuitive justification, but is in fact acceptable only on a very restricted understanding, since its generalisation is subject to the so-called revenge problem.

Metaethics, understood as a distinct branch of ethics, is often traced to G. E. Moore's 1903 classic, Principia Ethica. Whereas normative ethics is concerned to answer first-order moral questions about what is good and bad, right and wrong, metaethics is concerned to answer second-order non-moral questions about the semantics, metaphysics, and epistemology of moral thought and discourse. Moore has continued to exert a powerful influence, and the sixteen essays here (most of them specially written for the volume) represent the most (...) up-to-date work in metaethics after, and in some cases directly inspired by, the work of Moore. Contributors include Robert Audi, Stephen Barker, Paul Bloomfield, Panayot Butchvarvov, Jonathan Dancy, Stephen Darwall, Jamie Dreier, Allan Gibbard, Brad Hooker, Terry Horgan, Connie Rosati, Russ Shafer-Landau, Walter Sinnott-Armstrong, Michael Smith, Philip Stratton-Lake, Sigrun Svavarsdottir, Mark Timmons, and Judith Jarvis Thompson.

I present a view of conscious perception that supposes a processual unity between the activity in the brain and the perceived event in the external world. I use the rainbow to provide a first example, and subsequently extend the same rationale to more complex examples such as perception of objects, faces and movements. I use a process-based approach as an explanation of ordinary perception and other variants, such as illusions, memory, dreams and mental imagery. This approach provides new insights into (...) the problem of conscious representation and phenomenal consciousness. It is a form of anti- cranialism different from but related to other kinds of externalism. (shrink)
Throughout much of the modern period, the human mind has been regarded as a property of the brain and therefore something confined to the inside of the head—a view commonly known as ‘internalism’. But recent works in cognitive science, philosophy, and anthropology, as well as certain trends in the development of technology, suggest an emerging view of the mind as a process not confined to the brain but spread through the body and world—an outlook covered by a family of views (...) labelled ‘externalism’. In this paper, we will suggest there is now sufficient momentum in favour of externalism of various kinds to mark a historical shift in the way the mind is understood. We dub this emerging externalist tendency the ‘New Mind’. Key properties of the New Mind will be summarised and some of its implications considered in areas such as art and culture, technology, and the science of consciousness. (shrink)
In this paper I shall discuss the relationship between the two known Arabic translations of Aristotle’s Posterior Analytics and Avicenna’s Kitāb al-Burhān. I shall argue that Avicenna relies on both (1) Abū Bishr Mattā’s translation and (2) the anonymous translation used by Averroes in the Long Commentary as well as in the Middle Commentary (and also indirectly preserved by Gerard of Cremona’s Latin translation of Aristotle’s work). Although, generally speaking, the problem is relevant to the history of the transmission of (...) the Posterior Analytics from Greek through Syriac into Arabic, I do not intend to give a systematic presentation of the historical setting in which Aristotle’s work became readily available to the Arabo-Islamic culture. My aim here is rather to isolate and discuss some pieces of evidence concerning the texts that seem to have been available to Avicenna. In addition to that, I shall also provide evidence concerning the relationship with the Greek commentary tradition (in particular Philoponus and Themistius) that is likely to have influenced Avicenna in his discussion of Aristotle’s theory of demonstration and scientific knowledge.

This paper focuses on Plotinus’ account of the soul’s cognitive powers of sense perception and discursive thought, with particular reference to the treatises 3. 6 [26], 4. 4 [28] and 5. 3 [49] of the Enneads . Part 1 of the paper discusses Plotinus’ direct realism in perception. Parts 2 and 3 focus on Plotinus’ account of knowledge in Enneads 5. 3 [49] 2–3. Plotinus there argues that we make judgements regarding how the external world is by means of discursive (...) reasoning. This latter claim, however, is in tension with what Plotinus argues elsewhere regarding our perceptual apprehension of the external world (3. 6 [26] 1; 4. 4 [28] 23). This puzzle is addressed in Part 3 of the paper, which investigates Plotinus’ view that there exist some sense perceptions of which we are unaware. Finally, Part 4 looks at Plotinus’ understanding of Plato’s famous wax block analogy, in 5. 3 (49). The overall conclusion of the paper is that Plotinus’ account of knowledge is radically different from that of the Cartesian tradition. (shrink)
Biological and Cultural Bases of Human Inference addresses the interface between social science and cognitive science. In this volume, Viale and colleagues explore which human social cognitive powers evolve naturally and which are influenced by culture. Updating the debate between innatism and culturalism regarding human cognitive abilities, this book represents a much-needed articulation of these diverse bases of cognition. Chapters throughout the book provide social science and philosophical reflections, in addition to the perspective of evolutionary theory and the central assumptions (...) of cognitive science. The overall approach of the text is based on three complementary levels: adult performance, cognitive development, and cultural history and prehistory. Scholars from several disciplines contribute to this volume, including researchers in cognitive, developmental, social and evolutionary psychology, neuropsychology, cognitive anthropology, epistemology, and philosophy of mind. This contemporary, important collection appeals to researchers in the fields of cognitive, social, developmental, and evolutionary psychology and will prove valuable to researchers in the decision sciences.

Although many authors acknowledge the role of the environment in shaping the mind, the prevailing view holds that phenomenal experience is the outcome of neural activity taking place inside the nervous system. In philosophy of mind, this idea has gained so much strength that many authors assume that physicalism entails that phenomenal experience either emerges from or supervenes on neural activity.
What distinguishes a whole from an arbitrary sum of elements? I suggest a temporal and causal oriented approach. I defend two connected claims. The former is that existence is, by every means, coextensive with being the cause of a causal process. The latter is that a whole is the cause of a causal process with a joint effect. Thus, a whole is something that takes place in time. The approach endorses an unambiguous version of Restricted Composition that suits most commonsensical (...) intuitions about wholes. (shrink)
This paper considers philosophical approaches that are relevant to the intertwinement of logic, metaphysics, and psychology proposed by the Aquinas commentator Tommaso de Vio Cardinal Cajetan, the humanist Petrus Ramus, the pure Aristotelian Cornelius Martini, the Semi-Ramist Bartholomaeus Keckermann, and the lexicographer Rudolf Goclenius. Mostly, however, it is about Ramus and his followers, the Ramists, because of the role they played in exacerbating a discussion on the constitution of objectivity during the Renaissance that was to have an impact on Cartesian (...) andpost-Cartesian theories of subjectivity. Finally, keeping in mind that Kant was familiar with the secunda Petri, i.e., with the second part of Ramus's logic, namely the theory of judgment, some common ground is recognizable between Ramus and Kant as well.

The author discusses a number of topics related to the concept of legal order and the structure of legal orders. In particular, the following theses are challenged: (1) legal orders are sets of rules; (2) the criterion of membership to such sets is validity; (3) legal orders are dynamic sets; (4) legal orders are provided with a hierarchical configuration; (5) legal orders are coherent and consistent sets.
Yet we experience qualities. Thus qualities are an empirical fact. Even hard-core neuroscientists like Cristoph Koch have acknowledged it: “the provisional approach I take. . .is to consider first person experiences as brute facts of life and seek to explain them.” (Koch 2004: 7). But since objective knowledge of the world is independent of qualities, the world is supposed to be devoid of qualities. Qualities are supposed to emerge out of the subject – whatever the subject is.

: The object of G. F. Meier's Vernunftlehre and its abridgement for courses, the Auszug aus der Vernunftlehre, does not consist exclusively in the elaboration of the formal aspects of logic, but rather in the individuation of the elements of thought and language, which make human understanding possible. Instead of limiting himself to formal truth, Meier investigates the realms of epistemic, aesthetic, and historic truths, of horizons, and prejudices. Kant used both Meier's Vernunftlehre and its Auszug for about forty years (...) in his logic-lectures. Kant's Logik, and also his Kritik der reinen Vernunft, were thus strongly influenced by Meier.

Sensory motor contingencies belong to a functionalistic framework. Functionalism does not explain why and how objective functional relations produce phenomenal experience. O'Regan & Noë (O&N) as well as other functionalists do not propose a new ontology that could support the first person subjective phenomenal side of experience.
Most speakers experience unclarity about the application of predicates like tall and red to liminal cases. We formulate alternative psychological hypotheses about the nature of this unclarity, and report experiments that provide a partial test of them. A psychologized version of the ‘vagueness-as-ignorance’ theory is then advanced and defended.
Many important concepts of the calculus are difficult to grasp, and they may appear epistemologically unjustified. For example, how does a real function appear in “small” neighborhoods of its points? How does it appear at infinity? Diagrams allow us to overcome the difficulty in constructing representations of mathematical critical situations and objects. For example, they actually reveal the behavior of a real function not “close to” a point (as in the standard limit theory) but “in” the point. We are interested (...) in our research in the diagrams which play an optical role –microscopes and “microscopes within microscopes”, telescopes, windows, a mirror role (to externalize rough mental models), and an unveiling role (to help create new and interesting mathematical concepts, theories, and structures). In this paper we describe some examples of optical diagrams as a particular kind of epistemic mediator able to perform the explanatory abductive task of providing a better understanding of the calculus, through a non-standard model of analysis. We also maintain they can be used in many other different epistemological and cognitive situations. (shrink)
Homo sociologicus and homo oeconomicus are, for different reasons, unsatisfactory models for the social sciences. A third model, called rational model in the broad sense , seems better endowed to cope with the many different expressions of rationality of the social agent. Some contributions by Weber, Durkheim and Marx are early examples of the application of this model of social explanation based on good subjective reasons. According to this model and to the evidence of cognitive anthropology, it is possible to (...) reconcile primitive thinking with the inferential principles of Western people. Lastly, cognitive psychology can contribute to the discovery of generalizations of reason-based choices that can strengthen the explanatory power of rational model in the broad sense. (shrink)
Recent research on “causal cognition” in adults and infants shows that we can perceive singular causal relations not previously experienced. In particular, infants that are able to perceive causality seem to rely on innate beliefs and principles that allow a priori inference of a connection between cause and effect. Can causal cognition in infants justify the thesis of causal realism? On the one hand, it weakens the central pillar of the Humean arguments: the impossibility of a synthetic a priori causal (...) inference. On the other hand, if perception is the privileged way of justifying the reality of objects of the external world, that is valid in the case of causal relations as well. Moreover, the perception of causal relations, based on innate principles and beliefs, reflects the selective results of the interaction between the real constraints of the physical structure of the world and the evolution of the human mind.

Lehar tries to build a computational theory that succeeds in offering the same computational model for both phenomenal experience and visual processing. However, the vision that Lehar has about isomorphism in Gestalttheorie as representational, is not adequate. The main limit of Lehar's model derives from this misunderstanding of the relation between phenomenal and physiological levels.
This paper is devoted to stress the importance of the contribution of Gaetano Kanizsato contemporary psychology. His theoretical ideas have in many respects been truly seminal. In particular, are emphasized his distinction between the primary and secondary process, his criticism of the concept ofPrägnanz, and his focus on self-organisation in a dynamic approach. To continue his work, the main task is to identify the rules and constraints that enable us to see the world as it appears. In the last years (...) of his scientific work, his insight was that the non-linear dynamic approach may be the best way to achieve this goal, giving a more sound sense to the intuitions of Gestalt psychologie.Unfortunately, he died before he could reap the fruits of this insight. Here are reviewed the first results that some among his direct and indirect pupils have obtained in this direction. (shrink)
The problem of subjectivity, based on the generalizing substantification of the predicate subiective occurs first in the discussions of the postulates of Kant’s theory of knowledge. At issue is that a human being has focused on a matter, and that his subjectivity has the responsibility of isolating a determinate domain.In fact, it is up to the human subject to focus on objects and to thematize them according to his operative conditions, which is how it expresses different epistemic standpoints. Kant’s philosophy (...) provides the most adequate answers to the question about the anthropological conditioning of philosophy. My thesis is thattranscendental subjectivity includes an epistemic approach, which does not imply any kind of subjective conceptualism as opposed to forms of realism supported and structured by categories, it implies instead that without considering the epistemic standpoint, the question of the supposed primacy of transcendental over general logic or vice versa is irresoluble.

Perruchet & Vinter's provocative article challenges a series of interesting issues, yet the concept of isomorphism is troublesome for a series of reasons: (1) isomorphism entails some sort of dualism; (2) isomorphism does not entail that a piece of the world is a representation; and (3) it is extremely difficult to provide an explanation about the nature of the relation of isomorphism.
In this paper I will examine the relation between the theory of obligations and its use in sophismatic contexts through the lens of certain pragmatic concerns. In order to do this, I will take a sophism discussed by Peter of Mantua in his treatise on obligations as a case-study. I will first provide a brief outline of the structure of the treatise and then examine a concrete case that shows how the relationship between background assumptions (casus and context of utterance) (...) and criteria of response seems to suggest a way to qualify the application of general rules (especially for irrelevant sentences) in certain limit-cases. By discussing Peter's presentation of the sophism, I will also argue for a connection between Peter of Mantua's text and Mesino de Codronchi's Questiones on the De Interpretatione. (shrink)
Sharing a public language facilitates particularly efficient forms of joint perception and action by giving interlocutors refined tools for directing attention and aligning conceptual models and action. We hypothesized that interlocutors who flexibly align their linguistic practices and converge on a shared language will improve their cooperative performance on joint tasks. To test this prediction, we employed a novel experimental design, in which pairs of participants cooperated linguistically to solve a perceptual task. We found that dyad members generally showed a (...) high propensity to adapt to each other’s linguistic practices. However, although general linguistic alignment did not have a positive effect on performance, the alignment of particular task-relevant vocabularies strongly correlated with collective performance. In other words, the more dyad members selectively aligned linguistic tools fit for the task, the better they performed. Our work thus uncovers the interplay between social dynamics and sensitivity to task affordances in successful cooperation. (shrink)
What is the proper unit of analysis in the psycholinguistics of dialog? While classical approaches are largely based on models of individual linguistic processing, recent advances stress the social coordinative nature of dialog. In the influential interactive alignment model, dialogue is thus approached as the progressive entrainment of interlocutors' linguistic behaviors toward the alignment of situation models. Still, the driving mechanisms are attributed to individual cognition in the form of automatic structural priming. Challenging these ideas, we outline a dynamical framework (...) for studying dialog based on the notion of interpersonal synergy. Crucial to this synergetic model is the emphasis on dialog as an emergent, self-organizing, interpersonal system capable of functional coordination. A consequence of this model is that linguistic processes cannot be reduced to the workings of individual cognitive systems but must be approached also at the interpersonal level. From the synergy model follows a number of new predictions: beyond simple synchrony, good dialog affords complementary dynamics, constrained by contextual sensitivity and functional specificity. We substantiate our arguments by reference to recent empirical studies supporting the idea of dialog as interpersonal synergy. (shrink)
Human social coordination is often mediated by language. Through verbal dialogue, people direct each other's attention to properties of their shared environment, they discuss how to jointly solve problems, share their introspections, and distribute roles and assignments. In this article, we propose a dynamical framework for the study of the coordinative role of language. Based on a review of a number of recent experimental studies, we argue that shared symbolic patterns emerge and stabilize through a process of local reciprocal linguistic (...) alignment. Such patterns in turn come to facilitate and refine social coordination by enabling the alignment, joint construction and navigation of conceptual models and actions. Implications of the framework are illustrated and discussed in relation to a case study where dyads of interlocutors interact verbally to reach joint decisions in a perceptual discrimination task. Keywords: social coordination; language; communication; linguistic alignment; symbolic patterns; affordances; emergence; evolution; adaptivity; interaction. (shrink)
An agent often has a number of hypotheses, and must choose among them based on observations, or outcomes of experiments. Each of these observations can be viewed as providing evidence for or against various hypotheses. All the attempts to formalize this intuition up to now have assumed that associated with each hypothesis h there is a likelihood function μ h , which is a probability measure that intuitively describes how likely each observation is, conditional on h being the correct hypothesis. (...) We consider an extension of this framework where there is uncertainty as to which of a number of likelihood functions is appropriate, and discuss how one formal approach to defining evidence, which views evidence as a function from priors to posteriors, can be generalized to accommodate this uncertainty.

The empirical data do not unequivocally support a consistent fixed capacity of four chunks. We propose an alternative account whereby capacity is limited by the precision of specifying the temporal and spatial context in which items appear, that similar psychophysical constraints limit number estimation, and that short term memory (STM) is continuous with long term memory (LTM).
