Individual differences in emotional reactivity or affective style can be decomposed into more elementary constituents. Several separable of affective style are identified such as the threshold for reactivity, peak amplitude of response, the rise time to peak and the recovery time. latter two characteristics constitute components of affective chronometry The circuitry that underlies two fundamental forms of motivation and and withdrawal-related processes-is described. Data on differences in functional activity in certain components of these are next reviewed, with an emphasis on (...) the nomological network of surrounding individual differences in asymmetric prefrontal The relevance of such differences for understanding the nature affective dysfunction in affective disorders is then considered. The ends by considering what the prefrontal cortex “does” in certain of affective style and highlights some of the important questions for future research. (shrink)

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)
