Erotetic Search Scenarios

The concept of search scenario is explicated in terms of erotetic logic, i.e., the logic of questions. Different kinds of erotetic search scenarios are characterized. The basic logical properties of erotetic search scenarios are analyzed.     

A Cut-Free Sequent Calculus for Defeasible Erotetic Inferences

In recent years, the effort to formalize erotetic inferences—i.e., inferences to and from questions—has become a central concern for those working in erotetic logic. However, few have sought to formulate a proof theory for these inferences. To fill this lacuna, we construct a calculus for (classes of) sequents that are sound and complete for two species of erotetic inferences studied by Inferential Erotetic Logic (IEL): erotetic evocation and erotetic implication. While an effort has been made to axiomatize the former in a sequent system, there is currently no proof theory for the latter. Moreover, the extant axiomatization of erotetic evocation fails to capture its defeasible character and provides no rules for introducing or eliminating question-forming operators. In contrast, our calculus encodes defeasibility conditions on sequents and provides rules governing the introduction and elimination of erotetic formulas. We demonstrate that an elimination theorem holds for a version of the cut rule that applies to both declarative and erotetic formulas and that the rules for the axiomatic account of question evocation in IEL are admissible in our system.

     

Deduction and Reduction Theorems for Inferential Erotetic Logic

The concepts of question evocation and erotetic implication play central role in Inferential Erotetic Logic. In this paper, deduction theorems for question evocation and erotetic implication are proven. Moreover, it is shown how question evocation by a finite non-empty set of declaratives can be reduced to question evocation by the empty set, and how erotetic implication based on a finite non-empty set of declaratives can be reduced to a relation between questions only.     

An erotetic approach to explanation by specification

In earlier publications of the first author it was shown that intentional explanation of actions, functional explanation of biological traits and causal explanation of abnormal events share a common structure. They are called explanation by specification (of a goal, a biological function, an abnormal causal factor, respectively) as opposed to explanation by subsumption under a law. Explanation by specification is guided by a schematic train of thought, of which the argumentative steps not concerning questions were already shown to be logically valid (elementary) arguments.Independently, the second author developed a new, inferential approach to erotetic logic, the logic of questions. In this approach arguments resulting in questions, with declarative sentences and/or other questions as premises, are analyzed, and validity of such arguments is defined.In the present paper it is shown that all four kinds of erotetic argumentative steps occurring in the train of thought of explanation by specification are valid arguments in the sense of inferential erotetic logic. Hence, in view of the fact that the other argumentative steps were already shown to be valid, it may be concluded that the logical structure of explanation by specification can be as well-established as that of explanation by nomological subsumption. Moreover, explanation by specification provides some illustrations of the applicability of erotetic logic in everyday life and some empirical sciences.     

Erotetic Logic And Explanation By Abnormic Hypotheses

A relativized concept of a possiblecorrect answer to a why-question is introduced. Acertain procedure of looking for acceptable answers towhy-questions is analyzed in terms of erotetic logic,i.e., the logic of questions.     

Scientific problems and questions from a logical point of view

Scientific knowledge systems function as effective and specialized apparatus for formulating, analyzing and solving scientific problems. In science, problems become internal parts of the knowledge systems; thus they acquire new forms and properties in comparison with common-sense problems. Definite theoretical structures connected with problems and questions appear in the theory. Among them are erotetic expressions and languages, calculi and algebras of problems. On the basis of the structure-nominative reconstruction of a theory, the unified treatment of these structures is given. Methods of the theory of named sets are used in the logical analysis of problems and their systems. As a consequence a new formalized model of the problem part of theory is constructed.     

Illusory inferences with quantifiers

The psychological study of reasoning with quantifiers has predominantly focused on inference patterns studied by Aristotle about two millennia ago. Modern logic has shown a wealth of inference patterns involving quantifiers that are far beyond the expressive power of Aristotelian syllogisms, and whose psychology should be explored. We bring to light a novel class of fallacious inference patterns, some of which are so attractive that they are tantamount to cognitive illusions. In tandem with recent insights from linguistics that quantifiers like “some” are treated as wh-questions, these illusory inferences are predicted by the erotetic theory of reasoning, which postulates that a process akin to question asking and answering is behind human inference making.     

Semantic information and the network theory of account

The article addresses the problem of how semantic information can be upgraded to knowledge. The introductory section explains the technical terminology and the relevant background. Section 2 argues that, for semantic information to be upgraded to knowledge, it is necessary and sufficient to be embedded in a network of questions and answers that correctly accounts for it. Section 3 shows that an information flow network of type A fulfils such a requirement, by warranting that the erotetic deficit, characterising the target semantic information t by default, is correctly satisfied by the information flow of correct answers provided by an informational source s. Section 4 illustrates some of the major advantages of such a Network Theory of Account (NTA) and clears the ground of a few potential difficulties. Section 5 clarifies why NTA and an informational analysis of knowledge, according to which knowledge is accounted semantic information, is not subject to Gettier-type counterexamples. A concluding section briefly summarises the results obtained.     

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.     

Philosophical Intuition Is the Capacity to Recognize one’s Epistemic Position. An Old-Fashion Approach Based on Russell,Carnap, Wittgenstein,and Husserl

Philosophical intuition has become one of the most debated problems in recent years, largely due to the rise of the movement called experimental philosophy which challenged the conviction that philosophers have some special insight into abstract ideas such as being, knowledge, good and evil, intentional action, etc. In response to the challenge, some authors claim that there is a special cognitive faculty called philosophical intuition which delivers justification to philosophical theses, while some others deny it based on experimental results. A relatively smaller group of researchers aim at clarifying what the alleged intuition is. I follow the latter path. In this paper I argue that philosophical intuition is in the first place the capacity enabling one to what I refer to as the recognition of one’s epistemic position. The latter means becoming aware of the seemingly trivial “fact” that the way in which the world manifests itself depends on the cognitive apparatus one has, thereby propelling one to draw a distinction between appearances and reality. The recognition at stake is a very specific capacity to approach the world solely as it is experienced. This capacity, I argue, is the core and the defining feature of philosophical intuition. As part of my argumentation I also distinguish between the intuition in question and its different manifestations; and then introduce a novel notion of erotetic intuition. My argument is called “old-fashion” to emphasize the fact that I draw mostly on four figures who were pivotal in the twentieth- century philosophy and whose influence on the current debate concerning philosophical intuition should be, I believe, stronger than it is; I mean Russell, Carnap, Wittgenstein, and Husserl.

     

Approaches to Adolescent Smoking Cessation and Education

The role of the school in the control of smoking among adolescents is explored. Incidence and trends of smoking among youth are discussed and health consequences of smoking are explored. The role of the school in smoking prevention, cessation, and regulation also is described. Innovative educational strategies to prevent smoking are reviewed and model programs are described. School-based smoking cessation programs are reviewed and suggstions are made for the development of local programs. School policies on smoking are given. Recommendations are given for a comprehensive school program to control smoking.     

Feature importance in feature generation and typicality rating

Many theoretical models of cognition are based on the assumption that cognitive processes and representations are hierarchically structured. The issue of whether these hierarchies are mere constructs or conceptual tools, or whether they have psychological and neurological reality, is addressed. Theories across a range of cognitive domains are reviewed and four kinds of evidence are considered: behavioural, neuropsychological, ontogenetic, and logical. Logical constraints are identified in relation to operating principles of control, access, economy and analogy. The general characteristics of hierarchical structures and their advantages and disadvantages are discussed.     

Computational and statistical methods for analyzing event-related potential data

Some computational and statistical techniques that can be used in the analysis of event-related potential (ERP) data are demonstrated. The techniques are fairly elementary but go one step further than do simple area measurement or peak picking, which are most often used in ERP analysis. Both amplitude and latency measurement techniques are considered. Principal components analysis (PCA) and methods for electromyographic onset determination are presented in detail, and Woody filtering is discussed briefly. The techniques are introduced in a nontechnical, tutorial review style. One and the same existing data set is presented, to which the techniques are applied, and practical guidelines for their use are given. The methods are demonstrated against a background of theoretical notions that are related to the definition of ERP components.     

Structure and development of behavior systems

Behavior systems are particular organizations of cognitive structures that are called behavior mechanisms: perceptual, central, and motor. Thus, behavior systems are defined here in structural terms and not in terms of their functional characteristics. In young animals, behavior mechanisms often develop independently of functional experience, though specific types of experience are usually necessary for integrated systems to develop. These concepts are illustrated here by the dust-bathing, feeding, aggressive, and sexual systems of the fowl, which are considered to be typical of behavior systems in other species. Aspects of neural development are examined and found to facilitate our understanding of a wide range of developmental phenomena, such as critical periods and irreversibility. Finally, various examples of classical conditioning and instrumental learning are analyzed in terms of the type of structures involved, and they are related to general developmental processes.     

Similarity semantics and minimal changes of belief

Different similarity relations on sets are introduced, and their logical properties are investigated. Close relationships are shown to hold between similarity relations that are based on symmetrical difference and operators of belief contraction that are based on relational selection functions. Two new rationality criteria for minimal belief contraction, the maximizing property and the reducing property, are proposed.     

Events (Like Objects) Are Things,Can Have Affordance Properties,and Can Be Perceived

Stoffregen (target article, this issue) argues that events and affordances are qualitatively distinct properties; that affordances are animal and observer referential, whereas events are not; and that only affordances are perceived and events are not. In this commentary, I argue to the contrary-that events are perceived as well as affordances and that animals do not perceive disembodied properties anymore than they could perceive propertyless things. I argue that events are not properties but are substantial, spatiotemporal things that have properties. Events can exhibit affordances that must vary in scope to support the perceptually guided temporal evolution of behaviors.     

Substance Abuse Prevention:

Components of a successful substance abuse prevention program are discussed. Substance use and abuse trends in school-aged populations are briefly reviewed. Prevention program strategies deemed desirable through recent research efforts are incorporated in describing a model program. Educational approaches and substance abuse intervention strategies are differentiated. Program planning guideliens are presented and discussed. These guidelines are designed to establish and maintain school and community support for prevention programs.     

The Portrayal of Men's Family Roles in Television Commercials

This study examines the portrayal of men infamily roles, as fathers and husbands, on televisioncommercials. A content analysis of commercials airedduring football, daytime, and prime time is carried out. The sample size of characters is 944, mostof whom are middle-class, non-Hispanic whites. Men withchildren but no spouse are more likely to be shownduring football than are women with children but no spouse. Advertisements for computers andelectronics are more likely to include men with childrenbut no spouse than women with children but no spouse.Men appearing alone with children are more likely to be shown outside than women alone withchildren. Men are less likely to be portrayed cooking,cleaning, washing dishes, and shopping than women. Menwithout spouses are more likely to be shown with boys and less likely to be shown with infants thanwomen without spouses. Men are infrequently shown takingcare of a child and are never shown caring for girls.However, men are often shown teaching, reading, talking, eating, and playing with children. Tothe extent that men are shown as more involved in familylife, they still tend to depend largely on knowledge andactivities that are stereotypically male.     

Emotional Schema Therapy: A Meta‐experiential Model

The emotional schema model proposes that individuals differ in their interpretations, evaluations, and strategies about emotional experience. Fourteen dimensions that are related to problematic strategies of emotion regulation are identified. Specific interventions for several of these strategies are identified, and examples of implementation are described. Finally, problematic schemas about emotions—both on the part of patients and therapists—are described, and interventions for addressing these in therapy are provided.     

The Counseling Service in the Administrative Setting: Problems and Possible Solutions

Friction between counseling personnel and administrators affects the work of each. Background reasons for difficulties in working together are explored. Four areas offering possible remedial measures are examined: the nature of compromise, problems in communication, emotional health, and a framework for understanding behavior. Aspects of a program model are provided. Suggestions are made for specific areas in which data are needed and proposals for method are offered.
