One of science's greatest intellects examines how people and animals display fear, anger, and pleasure. Darwin based this 1872 study on his personal observations, which anticipated later findings in neuroscience. Abounding in anecdotes and literary quotations, the book is illustrated with 21 figures and seven photographic plates. Its direct approach, accessible to professionals and amateurs alike, continues to inspire and inform modern research in psychology.

Theories of emotions traditionally divide into two categories. According to some researchers, emotions are or essentially involve evaluative thoughts or judgments. These are called cognitive theories. According to other researchers, an emotion can occur without any thought. These are called non-cognitive theories. Some defenders of non-cognitive theories argue that emotions are action tendencies, others say they are feelings, and still others say they are affect programs, which encompass a range of internal and external events. One of the most celebrated non-cognitive (...) theories owes, independently, to William James and Carl Lange. According to them, emotions are perceptions of patterned changes in the body. I think the perceptual theory of emotions is basically correct, but it needs to be updated. In this discussion, I will offer a summary and defence.The question I am addressing bears on the question of modularity. Within cognitive science, there is a widespread view that perceptual systems are modular. (shrink)

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.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

Highly divergent accounts exist of the nature of emotional feelings. Following Lambie and Marcel (2002), that divergence is traced back to actual differences in experience that result from variations in the involvement and direction of attention during emotions. The dimensions of variation include first versus second order experience, world- versus self-focus, appraisal or action-readiness focus, and attention mode (synthetic-analytic, immersed-detached). It is argued that the most characteristic form during actual emotional events consists of the more or less immersed and synthetic (...) perception of an emotionally meaningful world or of oneself as emotionally meaningful. Meaning consists of perceived qualities that represent appraisal and action readiness. Although information from one's body is central for all emotion experience, it is not central in all emotion experience. Feeling of the body in a particular state represents detached analytic self-focused awareness only.Emotion experience not only represents a perspective on emotional reactions but also contributes to the constitution of those reactions, notably with respect to attention shifts, action initiation and action guidance, and emotion regulation. It is a major factor in constituting a representation of “self” and in establishing social coherence. (shrink)

Emotions are viewed as having evolved through their adaptive value in dealing with fundamental life-tasks. Each emotion has unique features: signal, physiology, and antecedent events. Each emotion also has characteristics in common with other emotions: rapid onset, short duration, unbidden occurrence, automatic appraisal, and coherence among responses. These shared and unique characteristics are the product of our evolution, and distinguish emotions from other affective phenomena.

In this paper, we suggest that affect meets the traditional definition of “cognition” such that the affect–cognition distinction is phenomenological, rather than ontological. We review how the affect–cognition distinction is not respected in the human brain, and discuss the neural mechanisms by which affect influences sensory processing. As a result of this sensory modulation, affect performs several basic “cognitive” functions. Affect appears to be necessary for normal conscious experience, language fluency, and memory. Finally, we suggest that understanding the differences between (...) affect and cognition will require systematic study of how the phenomenological distinction characterising the two comes about, and why such a distinction is functional.

The story of our lives is the story of our passions. We fall in love, we are gripped by scientific curiosity and religious fervor, we fear death and grieve for others, we humble ourselves in envy, jealousy, and resentment. In this remarkable book, Robert Solomon shares his fascination with the emotions and illuminates our passions in an exciting new way.

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

"Perception is not something that happens to us, or in us," writes Alva Noe. "It is something we do." In Action in Perception, Noe argues that perception and perceptual consciousness depend on capacities for action and thought — that ...

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

In this article a view of emotional experience is set out that conceives emotional experience as a kind of perceptual experience. It is argued that both this view is embodied both by neuroscience of emotion and developmental psychology of emotion, although a significant part of recent research in experimental psychology has resorted to a kind of emotional stimuli that hardly square with the non-negotiable insight that perceiving is scouting. Finally, it is suggested that social referencing is in the backstage of (...) socalled paradigmatic scenarios, which provide the basis for emotional learning and in which emotions are typically shown.

The primary difference between direct and inferential theories of perception concerns the location of perceptual content, the meaning of our perceptions. In inferential theories of perception, these meanings arise inside animals, based upon their interactions with the physical environment. Light, for example, bumps into receptors causing a sensation. The animal (or its brain) performs inferences on the sensation, yielding a meaningful perception. In direct theories of perception, on the other hand, meaning is in the environment, and perception does not depend (...) upon meaning- conferring inferences. Instead the animal simply gathers information from a meaning- laden environment. But if the environment contains meanings, then it cannot be merely physical. This places a heavy theoretical burden on direct theories of perception, a burden so severe that it may outweigh all the advantages to conceiving perception as. (shrink)
