Jane is calmly strolling through the forest one lovely day. Suddenly, a large spider drops in front of her face. She immediately freezes; her heart races; her hands tremble; her face broadcasts “fear.” She screams and runs away. Both before and after, she concedes that spiders in this forest are harmless.Jane's reaction to the spider contrasts greatly with the way she normally reacts to events. Normally, or so the story goes, Jane weighs her options thoughtfully, choosing a course of action (...) consistent with her beliefs and with the greatest benefit. Indeed, her reaction to the spider contrasts so greatly with calm, rational, deliberate, belief-consistent action that traditional folk psychology supposed two different kinds of mechanism are at work: animal-like emotion versus human reason. Her emotion explains her reaction to the spider. Her emotion made her do it. (shrink)

Efforts to bridge emotion theory with neurobiology can be facilitated by dynamic systems (DS) modeling. DS principles stipulate higher-order wholes emerging from lower-order constituents through bidirectional causal processes cognition relations. I then present a psychological model based on this reconceptualization, identifying trigger, self-amplification, and self-stabilization phases of emotion-appraisal states, leading to consolidating traits. The article goes on to describe neural structures and functions involved in appraisal and emotion, as well as DS mechanisms of integration by which they interact. These mechanisms (...) include nested feedback interactions, global effects of neuromodulation, vertical integration, action-monitoring, and synaptic plasticity, and they are modeled in terms of both functional integration and temporal synchronization. I end by elaborating the psychological model of emotion–appraisal states with reference to neural processes. (shrink)

Lewis has missed an excellent opportunity to concisely demonstrate that a dynamical system can provide a bridge between emotion theory and neurobiology.

A perfectly matched layer (PML) absorbing material composed of a uniaxial anisotropic material is presented for the truncation of finite-difference time-domain (FDTD) lattices. It is shown that the uniaxial PML material formulation is mathematically equivalent to the perfectly matched layer method published by Berenger (see J. Computat. Phys., Oct. 1994). However, unlike Berenger's technique, the uniaxial PML absorbing medium presented in this paper is based on a Maxwellian formulation. Numerical examples demonstrate that the FDTD implementation of the uniaxial PML medium (...) is stable, equal in effectiveness as compared to Berenger's PML medium, while being more computationally efficient.

Peter Goldie’s The Emotions is a fascinating account distinguished by its originality and breadth. Throughout, the account is well grounded in sound common sense, as Goldie lets his careful and sensitive interpretation of the phenomena drive his theory rather than the other way around.

In this urbane and witty book, Ronald de Sousa disputes the widespread notion that reason and emotion are natural antagonists.

Peter Goldie opens the path to a deeper understanding of our emotional lives through a lucid philosophical exploration of this surprisingly neglected topic. Drawing on philosophy, literature and science, Goldie considers the roles of culture and evolution in the development of our emotional capabilities. He examines the links between emotion, mood, and character, and places the emotions in the context of consciousness, thought, feeling, and imagination. He explains how it is that we are able to make sense of our own (...) and other people's emotions, and how we can explain the very human things which emotions lead us to do. He argues that it is only from the personal point of view that thoughts, reasons, feelings, and actions come into view. This fascinating book gives an accessible but penetrating exploration of an important but mysterious subject. Any reader interested in emotion and its role in understanding our lives will find much to think about here. (shrink)

In _Reconstructing the Cognitive World_, Michael Wheeler argues that we should turn away from the generically Cartesian philosophical foundations of much contemporary cognitive science research and proposes instead a Heideggerian approach. Wheeler begins with an interpretation of Descartes. He defines Cartesian psychology as a conceptual framework of explanatory principles and shows how each of these principles is part of the deep assumptions of orthodox cognitive science. Wheeler then turns to Heidegger's radically non-Cartesian account of everyday cognition, which, he argues, can (...) be used to articulate the philosophical foundations of a genuinely non-Cartesian cognitive science. Finding that Heidegger's critique of Cartesian thinking falls short, even when supported by Hubert Dreyfus's influential critique of orthodox artificial intelligence, Wheeler suggests a new Heideggerian approach. He points to recent research in "embodied-embedded" cognitive science and proposes a Heideggerian framework to identify, amplify, and clarify the underlying philosophical foundations of this new work. He focuses much of his investigation on recent work in artificial intelligence-oriented robotics, discussing, among other topics, the nature and status of representational explanation, and whether cognition is computation rather than a noncomputational phenomenon best described in the language of dynamical systems theory. Wheeler's argument draws on analytic philosophy, continental philosophy, and empirical work to "reconstruct" the philosophical foundations of cognitive science in a time of a fundamental shift away from a generically Cartesian approach. His analysis demonstrates that Heideggerian continental philosophy and naturalistic cognitive science need not be mutually exclusive and shows further that a Heideggerian framework can act as the "conceptual glue" for new work in cognitive science.

Gut Reactions is an interdisciplinary defense of the claim that emotions are perceptions of changes in the body.

Paul E. Griffiths argues that most research on the emotions has been as misguided as Aristotelian efforts to study "superlunary objects" - objects...

What are 'emotions'? This book offers a balanced survey of facts and theory.

DeLancey shows that our understanding of emotion provides essential insight on key issues in philosophy of mind and artificial intelligence. He offers us a bold new approach to the study of the mind based on the latest scientific research and provides an accessible overview of the science of emotion.

This article provides a retrospective, current and prospective overview on developments in brain research and neuroscience. Both theoretical and empirical studies are considered, with emphasis in the concept of multivariability and metastability in the brain. In this new view on the human brain, the potential multivariability of the neuronal networks appears to be far from continuous in time, but confined by the dynamics of short-term local and global metastable brain states. The article closes by suggesting some of the implications of (...) this view in future multidisciplinary brain research. (shrink)

How should we understand the emotional rationality? This first part will explore two models of cognition and analogy strategies, test their intuition about the emotional desire. I distinguish between subjective and objective desire, then presents with a feeling from the "paradigm of drama" export semantics, here our emotional repertoire is acquired all the learned, and our emotions in the form of an object is fixed. It is pretty well in line with the general principles of rationality, especially the lowest reasonable (...) principles. Turned to the second part of this side of reasonable. I will inquire how emotional beliefs, desires, and behaviors contribute to the rationality. I will present a very general biological hypothesis: emotions by controlling highlights the characteristics of perception and reasoning, so that we remove the difficulties due in particular to lead to paralysis; they are being simulated by a simplified perception of information, thus limiting our practice and cognitive choice. How are we to understand emotional or axiological rationality? I pursue analogies with both the cognitive and the strategic models, testing them against intuitions about emotional desires. We distinguish two different classes of desires, the subjective and the objective, and propose that emotions have a semantics that derives from "paradigmatic scenarios", in terms of which our emotional repertoire is learned and the formal objects of our emotions fixed. This fits in well with emerging facts about how our emotional capacities develop, and it can also be squared with the general principles of rationality, particularly minimal rationality. In the second part, I return to the perspective of rationality. I ask how emotions contribute to the rationality of beliefs, desires, and behavior. I proffer a very general biological hypothesis: Emotions spare us the paralysis potentially induced by a particular predicament by controlling the salience of features of perception and reasoning; they temporarily mimic the informational encapsulation of perception and so circumscribe our practical and cognitive options.

This article explores the idea that Core Affect provides the emotional quality to any conscious state. Core Affect is the neurophysiological state always accessible as simply feeling good or bad, energized or enervated, even if it is not always the focus of attention. Core Affect, alone or more typically combined with other psychological processes, is found in the experiences of feeling, mood and emotion, including the subjective experiences of fear, anger and other so-called basic emotions which are commonly thought to (...) be raw, primitive, and universal.
