Emotions are traditionally considered to be brief states that last for seconds or a few minutes at most. However, due to pioneering theoretical work of Frijda and recent empirical studies, it has become clear that the duration of emotions is actually highly variable with durations ranging from a few seconds to several hours, or even longer. We review research on determinants of emotion duration. Three classes of determinants are identified: features related to the emotion-eliciting event, emotion itself, and emotion-experiencing person. (...) Initial evidence on the psychological and neural mechanisms that underlie their effects is discussed. (shrink)

Research interest in topics such as happiness, the quality of life, and the experience of well-being has dramatically increased in the past four decades. Global measures of Subjective Well-Being have long held a prominent position in this burgeoning body of research. Despite their widespread acceptance and use, the validity and utility of global measures of SWB have been challenged at several levels of analysis. These critiques have ranged from the conceptual basis of SWB to very specific concerns about the context (...) of the assessment situation and the cognitive processes involved in formulating a response to such measures. The purpose of this paper is to review and address some of the more prominent critiques of global measures of SWB, and to discuss methodological procedures and strategies for minimizing threats to the validity and increasing the utility of global measures of SWB.

Computer software is written in languages like C, Java or Haskell. In many cases social software is expressed in natural language. The paper explores connections between the areas of natural language analysis and analysis of social protocols, and proposes an extended program for natural language semantics, where the goals of natural language communication are derived from the demands of specific social protocols.

There is a longstanding discussion on whether happiness is culturally relative or not. The available data suggest that all humans tend to assess how much they like their lives. The evaluation draws both on affective experience, which is linked to gratification of universal human needs and on cognitive comparison, which is framed by cultural standards of the good life. The overall appraisal seems to depend more on the former than on the latter source of information. Conditions for happiness appear to (...) be quite similar across the world and so are the consequences of enjoying life or not. There is more cultural variation in the valuation of happiness and in beliefs about conditions for happiness. The greatest variation is found in how happy people are. (shrink)

The brain is considered to be the primary generator and regulator of emotions; however, afferent signals originating throughout the body are detected by the autonomic nervous system (ANS) and brainstem, and, in turn, can modulate emotional processes. During stress and negative emotional states, levels of cardiorespiratory coherence (CRC) decrease, and a shift occurs toward sympathetic dominance. In contrast, CRC levels increase during more positive emotional states, and a shift occurs toward parasympathetic dominance. Te dynamic changes in CRC that accompany different (...) emotions can provide insights into how the activity of the limbic system and afferent feedback manifest as emotions. The authors propose that the brainstem and CRC are involved in important feedback mechanisms that modulate emotions and higher cortical areas. That mechanism may be one of many mechanisms that underlie the physiological and neurological changes that are experienced during pranayama and meditation and may support the use of those techniques to treat various mood disorders and reduce stress.
