The psychological and neurobiological processes underlying moral judgement have been the focus of many recent empirical studies1–11. Of central interest is whether emotions play a causal role in moral judgement, and, in parallel, how emotion-related areas of the brain contribute to moral judgement. Here we show that six patients with focal bilateral damage to the ventromedial prefrontal cortex (VMPC), a brain region necessary for the normal generation of emotions and, in particular, social emotions12–14, produce an abnor- mally ‘utilitarian’ pattern of (...) judgements on moral dilemmas that pit compelling considerations of aggregate welfare against highly emotionally aversive behaviours (for example, having to sacrifice one person’s life to save a number of other lives)7,8. In contrast, the VMPC patients’ judgements were normal in other classes of moral dilemmas. These findings indicate that, for a selective set of moral dilemmas, the VMPC is critical for normal judgements of right and wrong. The findings support a necessary role for emotion in the generation of those judgements. (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.

The meaning of spontaneous skin conductance activity, and its relevance to appraisal theory, are examined. Spontaneous skin conductance activity is hypothesised to reflect task engagement, and thus to be correlated with appraisals of problem-focused coping potential. In a within-subjects design, subjects solved anagrams in which task difficulty was manipulated by varying both the difficulty of the anagrams and the amount of time available to solve them. In the most difficult condition, appraisals of coping potential were expected, and observed, to be (...) especially low, and these appraisals were predicted to produce selective disengagement from the task, yielding reduced skin conductance activity. Within trials, skin conductance activity increased at the start of the trials in all conditions, but decreased by the end of the trials in the most difficult condition only. At the end of the trials, both spontaneous response rate and maximum response amplitude were positively correlated, within-subjects, with appraisals of coping potential, and, even after controlling for task difficulty, with solving the anagram. These findings support the hypothesised relation between appraised coping potential and spontaneous skin conductance activity, and the interpretation of this activity as reflecting task engagement.

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.

There is a growing consensus that the elicitation and differentiation of emotions can best be understood as the result of the subjective appraisal of the significance of events for individuals. The present paper addresses the process of appraisal, hitherto neglected; particularly the postulate that appraisal consists of a fixed sequence of stimulus evaluation checks, as proposed by the component process model of emotion (Scherer, 1984, 1993b). It is suggested that indirect evidence pertinent to the order assumption, which is an essential (...) aspect of the sequence hypothesis, can be obtained via the study of recognition-of-emotion-situation scenarios that have been segmented according to individual appraisal criteria or dimensions. The hypothesis that the presentation of these segments in the predicted sequence (as compared to a random sequence) will result in a faster and more accurate identification of the respective emotions is supported by data from three experiments. Potential alternative explanations are discussed. (shrink)

This paper proposes a theory of how conscious emotional experience is produced by the brain as the result of many interacting brain areas coordinated in working memory. These brain areas integrate perceptions of bodily states of an organism with cognitive appraisals of its current situation. Emotions are neural processes that represent the overall cognitive and somatic state of the organism. Conscious experience arises when neural representations achieve high activation as part of working memory. This theory explains numerous phenomena concerning emotional (...) consciousness, including differentiation, integration, intensity, valence, and change. Ó 2007 Elsevier Inc. All rights reserved.

Emotion is normally regulated in the human brain by a complex circuit consisting of the orbital frontal cortex, amygdala, anterior cingulate cortex, and several other interconnected regions. There are both genetic and environmental contributions to the structure and function of this circuitry. We posit that impulsive aggression and violence arise as a consequence of faulty emotion regulation. Indeed, the prefrontal cortex receives a major serotonergic projection, which is dysfunctional in individuals who show impulsive violence. Individuals vulnerable to faulty regulation of (...) negative emotion are at risk for violence and aggression. Research on the neural circuitry of emotion regulation suggests new avenues of intervention for such at-risk populations. (shrink)
