A Lewisian Semantics for S2

This paper sets out a semantics for C.I. Lewis's logic S2 based on the ontology of his 1923 paper ‘Facts, Systems, and the Unity of the World’. In that article, worlds are taken to be maximal consistent systems. A system, moreover, is a collection of facts that is closed under logical entailment and conjunction. In this paper, instead of defining systems in terms of logical entailment, I use certain ideas in Lewis's epistemology and philosophy of logic to define a class of models in which systems are taken to be primitive elements but bear certain relations to one another. I prove soundness and completeness for S2 over this class of models and argue that this semantics makes sense of at least a substantial fragment of Lewis's logical theory.     

Optimal psychological states in advanced climbers: Antecedents,characteristics, and consequences of flow and clutch states

ObjectivesOptimal psychological states (e.g., flow) are particularly valued by rock-climbers. The integrated model of flow and clutch states has shown promise for better understanding optimal states in sport psychology. The current study examined the antecedents, characteristics, and consequences of these states among rock-climbers in relation to the integrated model. A secondary objective was to compare optimal psychological states across outdoor and indoor rock-climbing contexts.DesignA sequential-explanatory (QUAN → qual) design was used.MethodNine male and four female advanced rock-climbers completed a flow questionnaire immediately after every climbing route during two separate climbing sessions (i.e., one outdoor, one indoor). Intensity sampling was used to identify participants for 13 semi-structured interviews, based on high- or low-score thresholds established by the research team. Data were analysed using reflexive thematic analysis and abductive reasoning.ResultsParticipants reported an optimal state during at least one of their climbs in 72% of their outdoor sessions and 40% of their indoor sessions. A focus on exploring routes was reported as preceding flow states, which were characterised by enjoyment of effortless movement for its own sake. In contrast, specific goals and additional risk-based pressure were reported as preceding clutch states, which were described as exerting maximal effort. After experiencing flow, participants reported additional vitality. Following clutch states, participants reported feeling accomplished, despite reporting exhaustion.ConclusionsThis study suggests potential antecedents, characteristics, and consequences of two distinct, yet overlapping, optimal states that appear to occur during both indoor and outdoor climbing. Findings extend understanding of the integrated flow and clutch state model beyond traditional sport and exercise contexts and demonstrates the utility of the model for adventure recreation. Recommendations for future research include testing, refining, and expanding the integrated model of flow and clutch.     

A model clarifying the role of mediators in the variability of mood states over time in people who stutter

PurposeElevated negative mood states such as social anxiety and depressive mood have been found in adults who stutter. Research is needed to assist in the development of a model that clarifies how factors like self-efficacy and social support contribute to the variability of negative mood states over time.MethodParticipants included 200 adults who stutter. A longitudinal design was employed to assess change in mood states over a period of five months. Hierarchical directed regression (path analysis) was used to determine contributory relationships between change in mood states and self-efficacy, social support, socio-demographic and stuttering disorder variables. Participants completed a comprehensive assessment regimen, including validated measures of mood states, perceived control (self-efficacy) and social support.ResultsResults confirmed that self-efficacy performs a protective role in the change in mood states like anxiety and depressive mood. That is, self-efficacy cushioned the impact of negative mood states. Social support was only found to contribute a limited protective influence. Socio-demographic variables had little direct impact on mood states, while perceived severity of stuttering also failed to contribute directly to mood at any time point.ConclusionsMood was found to be influenced by factors that are arguably important for a person to cope and adjust adaptively to the adversity associated with fluency disorder. A model that explains how mood states are influenced over time is described. Implications of these results for managing adults who stutter with elevated negative mood states like social anxiety are discussed.Educational Objectives: The reader will be able to describe: (a) the method involved in hierarchical (directed) regression used in path analysis; (b) the variability of mood states over a period of five months; (c) the nature of the mediator relationship between factors like self-efficacy and social support and mood states like anxiety, and (d) the contribution to mood states of socio-demographic factors like age and education and stuttering disorder variables like stuttering frequency and perceived severity.     

The effects of open vs. specific goals on flow and clutch states in a cognitive task

ObjectivesRecent qualitative evidence suggests that two optimal psychological states (flow and clutch) underlie excellent performance in sport. That research further suggests that the type of goal pursued influences which state is experienced. This study aimed to examine the effects of goal types (i.e., open, specific, and do-your-best goals) on flow and clutch states during performance in a cognitive task, which was developed and has been used in sport. Secondary aims were to investigate the effects of goal types on objective and subjective performance, confidence, and perceived challenge.DesignThis study employed a repeated measure design (mixed model).MethodParticipants (N = 95; M_age = 24.89, SD = 9.27) were randomised to one of three goal conditions and asked to perform a Letter and Number Identification Task, which was repeated for six attempts.ResultsParticipants prescribed open or do-your-best goals experienced significantly higher levels of flow than those prescribed specific goals, who conversely experienced significantly higher levels of clutch states. Participants assigned specific goals performed significantly better than those prescribed open or do-your-best goals. Those assigned open or do-your-best-goals reported greater perceived performance, higher confidence, and feeling more optimally challenged.ConclusionsThese findings provide experimental support for the role of goal types in determining flow and clutch states, and further understanding of the psychological effects of these goal types. Implications are discussed, and recommendations are made for future research into the role of goals in experiencing flow and clutch states in sport and exercise.     

Separation of Religion and State and Secularism in Theory and in Practice

Abstract

This study examines whether states follow the religion policies they declare in their constitutions. It identifies four types of policies which officially seek to limit religion's role in government: absolute separation of religion and state (SRAS); neutral political concern; exclusion of ideals; and secularism–laicism. I determine whether states follow these policies using the religion and state (RAS) dataset and compare this to constitutional declarations that the state is secular and declarations of separation of religion and state. The results show that a majority of states which make both types of declaration do not follow these policies based on any of the four standards used in this study. However, the presence and wording of these clauses are correlated with state religion policy.     

Descartes on the distinction between primary and secondary qualities

ABSTRACT

Descartes did not use the terms ‘primary’ and ‘secondary’ qualities, but a similar distinction emerges from his texts: certain qualities of objects (such as size and shape) are intrinsic properties of matter, whereas others (like colours and smells) are products of the interaction with a perceiver. A common interpretation states that the division between primary and secondary qualities is explained by the way in which we are acquainted with them: an idea of a primary quality is similar to its physical causes, and it is clearly and distinctly perceived by the intellect. An idea of a secondary quality is dissimilar to its physical causes and it is obscurely and confusedly perceived by the senses. This view receives the name of ‘bifurcation reading’ (Simmons, A. ‘Descartes on the Cognitive Structure of Sensory Experience’. Philosophy and Phenomenological Research, LXVII, no. 3 (November 2003)). While it integrates well some textual occurrences, it creates a problematic fragmentation within single acts of perception. This paper contends that this reading is incorrect. It presents several arguments for the claim that the distinction of qualities is due to the different ways in which our ideas of them misrepresent their physical causes. Then, Descartes’ dissimilarity thesis between physical objects and our ideas of them remains a structural feature of his theory of sensory perception and not a local phenomenon affecting only ideas of secondary qualities.     

Recognition memory and awareness: An experiential approach

Abstract

This article reviews recent studies that have adopted an experiential approach to recognition memory and awareness. This approach measures two subjective states of awareness in recognition memory, remembering (or conscious recollection) and knowing (or familiarity). There is now evidence of quite a few experimental dissociations between these two states of awareness. These dissociations impose additional constraints on theories about relations between awareness and memory systems or processes.     

Davidson on the Identity Theory

Abstract

… if we bear well in mind the scope of our senses and what it is exactly that reaches our faculty of thinking by way of them, we must admit that in no case are the ideas of things presented to us by the senses just as we form them in our thinking. So much so that there is nothing in our ideas which is not innate to the mind or the faculty of thinking, with the sole exception of those circumstances which relate to experience, such as the fact that we judge that this or that idea which we now have immediately before our mind refers to a certain thing situated outside us. We make such a judgment not because these things transmit the ideas to our mind through the sense organs, but because they transmit something which, at exactly that moment, gives the mind occasion to form these ideas by means of the faculty innate to it. Nothing reaches our mind from external objects through the sense organs except certain corporeal motions… in accordance with my own principles. But neither the motions themselves nor the figures arising from them are conceived by us exactly as they occur in the sense organs, as I have explained at length in my Optics. Hence it follows that the very ideas of the motions themselves and of the figures are innate in us. The ideas of pains, colors, sounds and the like must be all the more innate if, on the occasion of certain corporeal motions, our mind is to be capable of representing them to itself, for there is no similarity between these ideas and the corporeal motions.     

Models for normal intuitionistic modal logics

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.     

A Psychological Means for the Control and Prevention of Industrial Stress in Computerized Working Places

Abstract

There are common traditions in investigations into industrial stress and other kinds of poor workers' states in Western and Russian/Soviet applied psychology. Based upon these traditions we attempt to overview the main domains of research and possibilities for their application in a practical sense. Proposed psychodiagnostic and psychoprophylactic approaches have to be developed according to different kinds of work situations and technological progress. But the intention of basing research on the analysis of structural mechanisms of activity regulation seems to us the most productive in all of these cases. It corresponds to the increasing demands on human internal resources and mental activities in modern technological systems.     

Religious and Political Violence: Globalising Syncretism and the Governance State*

Abstract

In this paper we argue that the conjunctions of religion and politics through eruptions of violence are codetermined and codependent through syncretic manifestations rather than a result of some kind of basic clash between different, self-contained systems of ideas and values. The vicissitudes of religious fervour are linked to issues of development and social change in which long-cherished traditions are confronted by seemingly inexorable forces beyond the control of those being affected by them. Religious violence is a political movement which should be understood as not being outside modernisation in the sense of being opposed to it; it is in fact part of the development of modernisation. Resistance arises from the experience of being excluded from the fruits of modernity while at the same time being enmeshed within the multiple social relations underpinning the production and distribution of those ‘fruits’. Whether from a postmodern or from a more conventional perspective a totalising analysis organised around master concepts like ‘globalisation’ or ‘civilisation’ is often developed to explain the intersections of religion and violence. We reject these approaches in favour of one predicated on the idea of the ‘governance state’. It is our argument that this better captures the core axis of analysis – namely the changing nature of the state and its management of populations and the concomitant forms of resistance by those subjected to it in an era in which such ‘modernities’ are played out.     

Hopeful + Hoping = Hope: unique experiential features in the measurement of emotion

Abstract

Distinct differences have been found between hope and optimism based on retrospective stories. This study sought to replicate those findings when anticipating outcomes in real-time and examine whether they are affected by different lexical formulations of the word hope. One-hundred and two participants read two first-person, chronological vignettes. They rated their hope, optimism, fear, and worry about the anticipated outcome following each part of the story; they also rated their appraisals of importance, likelihood, and perceived control. Half of the participants read adjective forms of the states (e.g. hopeful) and half read verb forms (e.g. hoping). Differences in ratings for the adjective and verb forms were found for hope but not the other anticipatory states, and both forms of hope were found to differ from optimism. Implications of these lexical differences for understanding and measuring the experience of hope are discussed.     

Nietzsche on the Nature of the Unconscious

Abstract

This paper argues that Nietzsche develops a novel and compelling account of the distinction between conscious and unconscious mental states: he argues that conscious mental states are those with conceptual content, whereas unconscious mental states are those with nonconceptual content. I show that Nietzsche’s puzzling claim that consciousness is ‘superficial’ and ‘falsifying’ can be given a straightforward explanation if we accept this understanding of the conscious/unconscious distinction. I originally defended this view in my ‘Nietzsche’s Theory of Mind: Consciousness and Conceptualization’ (2005, European Journal of Philosophy 13: 1–31); since then, the view has come under criticism on several fronts. Brian Leiter and others suggest that there is not enough textual evidence for the view. In addition, Leiter, Mattia Riccardi and Tsarina Doyle argue that, rather than aligning the conscious/unconscious distinction with the conceptual/nonconceptual distinction, Nietzsche endorses a higher-order thought model of consciousness. Riccardi also objects that Nietzsche must treat some unconscious mental states as conceptual. In this essay, I defend the interpretation in light of these objections. I provide new textual evidence for the interpretation, show that Nietzsche extracted aspects of the view from Schopenhauer’s work on consciousness, consider the possibility that Nietzsche endorses a higher-order thought theory, and respond to Riccardi’s objection.     

GUIDED READING IN POETRY: COMBINING AESTHETIC APPRECIATION AND DEVELOPMENT OF ESSENTIAL SKILLS

Reading and sharing poetry fosters richness in languages and encourages understanding of ideas presented through a beautiful form of expression. Poetry takes the reader through expression of emotion and the ideas that these emotions inspire in the poet. Further, the poet stimulates the reader to explore his or her own feelings and ideas. Discussion of what a particular poem means to individual students provides opportunities to share ideas and feelings which the poem evokes.

The use of poetry invites students to read lines or particular phrases which are appealing to them or about which they have a question. Furthermore, teachers should be encouraged to combine the aesthetic dimensions of poetry with skills development. A poetry guide for encouraging basic language skills is presented herein.     

The relationship between negative urgency and generalized anxiety disorder symptoms: the role of intolerance of negative emotions and intolerance of uncertainty

Background and Objectives: GAD symptoms are associated with greater negative urgency, a dimension of impulsivity defined as the tendency to act rashly when distressed. This study examined the degree to which intolerance of negative emotional states and intolerance of uncertainty account for the association between negative urgency and GAD symptoms. Design: An analysis of indirect effects evaluated whether intolerance of negative emotions and intolerance of uncertainty uniquely account for the association between negative urgency and GAD symptom severity. Methods: Undergraduate students (N?=?308) completed measures of GAD symptoms, trait anxiety, negative urgency, distress tolerance, and intolerance of uncertainty. Results: Greater symptoms of GAD, intolerance of negative emotional states, and intolerance of uncertainty were associated with greater negative urgency. There was an indirect relationship between negative urgency and GAD symptoms through intolerance of negative emotional states and intolerance of uncertainty even when controlling for trait anxiety. Intolerance of negative emotional states and intolerance of uncertainty each had an indirect relationship with GAD severity through negative urgency, suggesting possible bi-directional relations. Conclusions: Future studies should examine the role of intolerance of negative emotional states and intolerance of uncertainty in the impulsive behavior of individuals with GAD, and whether impulsive behavior reinforces these processes.     

Coping as a building mechanism to explain the unique association of affect and goal motivation with changes in affective states

Background and objectives: In this study, we examined the mediating role of university students’ coping strategies in the unique/additive influence of affective states and goal motivation on upward changes in affect during a midterm exam period. Design: Using a short-term prospective design, key assumptions from the self-concordance model and the broaden-and-build theory were drawn upon to determine whether coping strategies are influenced by goal motivation and affective states, while also subsequently influencing short-term changes in affective states during a semester. Method: A sample of 272 students (79% females and 21% males) participated in a study in which they completed questionnaires twice during the semester. Results: Results of structural equation modeling, using a true latent change approach, have generally supported our hypotheses. Positive affective states and autonomous goal motivation prospectively predicted task-oriented coping which, in turn, was associated with increases in positive affect. Negative affective states and controlled goal motivation prospectively predicted disengagement-oriented coping which, in turn, was associated with increases in negative affect. Conclusion: Coping partially mediates the unique association of affect and goal motivation with changes in affective states of university students.     

Brain Systems that Mediate both Emotion and Cognition

Abstract

Neurobiological research with animals strongly suggests that the brain systems which mediate emotion overlap with those that mediate cognition to such a degree that it is difficult, if not impossible, to maintain any clear distinction between them. Possible reasons for this overlap are discussed; and a model of brain systems that simultaneously subserve emotion and cognition is presented. The model postulates the existence of three fundamental systems of this kind in the mammalian brain: a behavioural approach system, a fight/flight system, and a behavioural inhibition system. The neuropsychology of each of these systems is briefly presented.     

Pop-in phenomenon in MgO and LiF: Observation of dislocation structures

This letter is based on recent progress in the observation of dislocation distributions around nanoindentations by chemical etching. This so-called nanoetching technique is used to determine the dislocation mechanisms associated with the pop-in phenomenon in MgO and LiF. Successive stages of highly controlled chemomechanical polishing have revealed that these dislocations are half-loops lying in the classical slip systems of MgO or LiF. However, they do not extend on the surface in the classical rosette-arms pattern but stay concentrated around the imprint. A mechanism of dislocation interactions, enhanced by the fact that the dislocations are suddenly nucleated in a small volume, is proposed to explain this specific distribution.     

Age similarities in matching pro- and contra-hedonic emotional strategies to everyday scenarios

ABSTRACT

Older adults are motivated to maximize positive affect in the present. Young adults will purposely feel negative and high arousal emotions in order to achieve a goal. However, this type of contra-hedonic emotional alignment has not been extensively studied with older adults. We expected older adults are less likely than young adults to select high arousal and negative emotions within specific scenarios where those states could be useful. In two studies, participants selected the emotion they preferred in hypothetical problems that varied on the arousal and valence best suited for goal achievement. Young and older adults were equally likely to endorse affective strategies that matched both pro and contra-hedonic scenarios. While older adults may be generally motivated to avoid negative and high-arousing emotions, they are just as likely as young adults to indicate that these states could be helpful in certain situations.
