Game-theoretical semantics for Peirce's existential graphs

In this paper, a game-theoretical semantics is developed for the so-called alpha part of Charles S. Peirce's System of Existential Graphs of 1896. This alpha part is that portion of Peirce's graphs that corresponds to propositional logic. The paper both expounds a game-theoretical semantics for the graphs that seems close to Peirce's own intentions and proves for the alpha part of the graphs that this semantics is adequate.     

Attention,consciousness, and the semantics of questions

Attention influences the character of conscious perceptual experience in intricate and surprising ways, including our experience of contrast, space, and time. These patterns of influence have been argued to cause trouble for the attractive thesis that differences in the character of conscious experience flow from differences in what we represent (Block 2010). I present a novel theory of the functional role of attention that has the resources for a systematic representationalist account of these phenomena. On the erotetic theory of attention, we bring an interest to the task of perception, captured as a question we seek to answer. Questions, as understood here, are contents that cognitive systems can represent rather than sentences. We process perceptual input as a putative answer to our question in a way that is modulated by attentional focus; attentional focus aims to pick out something that matches what our question is “about.” In certain cases, this yields a form of predictive coding: if the contribution of focus matches what our question is about, we take it to select one of the possible answers we are entertaining, even though our perceptual input by itself does not supply a full answer. The proposed account also provides a new account of the phenomenology of salience.

Expectancy,value, and attitudinal semantics

A novel single-attribute test between competing expectancy-value models of attitude was devised using subjects' ratings of clusters of statements located at a range of points within a three-dimensional semantic space with expectancy, value and attitude as the co-ordinates. The data provided strongest support for a model using bipolar scoring for evaluation and unipolar scoring for expectancy.     

Realism,inferential semantics,and the truth norm

Characteristic of neo-pragmatism is a commitment to deflationism about semantic properties, and inferentialism about conceptual content. It is usually thought that deflationism undermines the distinction between realistic discourses and others, and that the neo-pragmatists, unlike the classical pragmatists, cannot recognize that truth is a norm of belief and inquiry. I argue, however, that (1) the distinction between realistic discourses and others can be maintained even in the face of a commitment to deflationism, and (2) that deflationists can recognize that truth is a norm of belief and inquiry. If deflationism is true, realistic discourses, it turns out, are those that are inferentially integrated with a large body of other commitments, whereas those that call for an anti-realist treatment are inferentially isolated. Now, Grimm has persuasively argued that inquiry aims at achieving understanding, and that to understand something is, roughly, to grasp a large body of inferential connections in which it features. So, if he is right, realistic discourses are those in which the aim of inquiry can be achieved. This fact, together with an inferential theory of conceptual content, will, I argue, allow neo-pragmatists to recognize truth as a norm of belief and inquiry, despite their commitment to deflationism.

     

Actualism,ontological commitment,and possible world semantics

Actualism is the doctrine that the only things there are, that have being in any sense, are the things that actually exist. In particular, actualism eschews possibilism, the doctrine that there are merely possible objects. It is widely held that one cannot both be an actualist and at the same time take possible world semantics seriously — that is, take it as the basis for a genuine theory of truth for modal languages, or look to it for insight into the modal structure of reality. For possible world semantics, it is supposed, commits one to possibilism. In this paper I take issue with this view. To the contrary, I argue that one can take possible world semantics seriously and yet remain in full compliance with actualist scruples.     

'Questions, questions, questions!' A comparison of therapist inferences and parental responses to systemic questions

Using a specially designed questionnaire, we examined the relationship between parental responses to systemic questions, therapists'views based upon these responses and parental reports of dysfunction in a member of the family. The questionnaire was completed by parents of a randomly selected population sample of adolescents and by experienced family therapists. Therapists made inferences that were predictable, coherent and reliable. They gave most salience to the concept of'enmeshment'and least to'hostile-discordant'functioning. Some enmeshed answers were favoured by substantial proportions of parents, suggesting that they may reflect normal variants of family functioning. However no associations between total enmeshment scores and reported mental health problems were found. Hostile-discordant functioning, as assessed in this study, was rare in the general population sample, but was associated with reported problems.
