The study of emotional changes after brain injury has contributed enormously to the understanding of the neural basis of emotion. However, little attention has been placed on the methods used to elicit emotional responses in people with brain damage. Of particular interest are subjects with right hemisphere [RH] cortical lesions, who have been described as presenting impairment in emotional processing. In this article, an internal and external mood induction procedure [MIP] was used to trigger positive and negative emotions, in a (...) sample of 10 participants with RH damage, and 15 healthy controls. Emotional experience was registered by using a self-report questionnaire. As observed in previous studies, internal and external MIPs were equally effective in eliciting the target emotion, but the internal procedure generated higher levels of intensity. Remarkably, participants with RH lesions were equally able to experience both positive and negative affect. The results are discussed in relation to the role of the RH in the capacity to experience negative emotions. (shrink)

What determines the subjective intensity of emotions? Four major groups of determinants are hypothesised: concerns (strength and relevance), appraisal, regulation, and individual differences. During six weeks subjects reported an emotion every week and answered questions on a computer. It appears that all four groups of supposed determinants are correlated with emotional intensity, the concern variables show the highest correlations. The importance of the determinants is not always the same, there are differences between the emotions and between the dimensions of emotional (...) intensity. The relation between regulation and emotional intensity is complex: Causal relations are expected in both directions. On the one hand, a more intense emotion requires more regulation (positive causal effect), and on the other, regulation will decrease the intensity (negative causal effect). Indications of the existence of both relations are found. Regulation and intensity are positively correlated. The canonical correlation of overall felt intensity and the regulation effort with the determinants is higher than the multiple correlation of only the overall felt intensity with the determinants.

Emotion experience reflects some of the outcomes of the mostly nonconscious processes that compose emotions. In my view, the major processes are appraisal, affect, action readiness, and autonomic arousal. The phenomenology of emotion experience varies according to mode of consciousness (nonreflective or reflective consciousness), and to direction and mode of attention. As a result, emotion experience may be either ineffable or articulate with respect to any or all of the underlying processes. In addition, emotion experience reflects the degree to which (...) the emotion processes control perception, thought, action and bodily arousal. (shrink)

Intensity profiles of emotional experience over time have been found to differ primarily in explosiveness and accumulation. However, the determinants of these temporal features remain poorly understood. In two studies, we examined whether emotion regulation strategies are predictive of the degree of explosiveness and accumulation of negative emotional episodes. Participants were asked to draw profiles reflecting changes in the intensity of emotions elicited either by negative social feedback in the lab or by negative events in daily life. In addition, trait, (...) and state usage of a set of emotion regulation strategies was assessed. Multilevel analyses revealed that trait rumination was positively associated with emotion accumulation. State rumination was also positively associated with emotion accumulation and, to a lesser extent, with emotion explosiveness. These results provide support for emotion regulation theories, which hypothesise that rumination is a central mechanism underlying the maintenance of negative emotions. (shrink)

ignette and autobiographical recall studies have often been used to test models of the appraisals associated with specific emotions. Recently, critiques of both methodologies have called into question the applicability of appraisal theory to naturally-occurring emotional responses. This study examined supporter's responses to Ross Perot's withdrawal from the 1992 presidential race to assess the extent to which appraisal models accurately capture responses to a naturally-occurring event. Supporters in Riverside County, California (N = 227) completed questionnaires concerning their interpretations of the (...) event, their initial emotional reactions, changes in their reactions in the weeks immediately following Perot's withdrawal, and their plans. Appraisal models correctly predicted the dimensions of agency and coping potential that served to differentiate sadness from anger, and the appraisals and plans associated with hope. Appraisal models did not predict the strong focus of sad supporters on their past goals and beliefs, and the plans associated with sadness and anger. Changes in emotional intensity occurred as a function of changes in goals and plans rather than merely as a function of time. These findings demonstrate the applicability of appraisal theory to naturally-occurring emotional responses, but also show that models may understate the complexity of the planning processes associated with emotions.

Some researchers claim that uncertainty prolongs the duration of emotional experiences because uncertainty toward an emotion-eliciting event prolongs attention to that event. However, some results contradict this claim. We assumed that curiosity rather than uncertainty prolongs the duration of emotional experience via attention, and that attention and emotional experience are prolonged only when uncertainty elicits curiosity. This assumption is based on the information gap theory, which proposes that curiosity increases with uncertainty, but that curiosity decreases at a certain level of (...) uncertainty. We conducted a survey study to investigate the relationships among curiosity, uncertainty, attention and duration of positive and negative emotional experiences. The results showed that curiosity, but not uncertainty, prolonged the duration of emotional experiences and the process was completely mediated by attention both for positive and negative emotions. Moreover, uncertainty prolonged the duration of emotional experiences only when uncertainty elicited curiosity, which in turn prolonged attention to the emotion-eliciting event. (shrink)

Emotion theorists have long held that a fundamental characteristic of an emotion is how its constituent processes change and interact over time. Assessing these temporal dynamics of emotion in the brain is critical for understanding the neural representation of emotions as well as advancing theories of emotional processing. We review the neuroimaging research on three temporal dynamic features of emotion: time of onset, duration, and resurgence and show how assessing these temporal dynamics in the brain have led to improved understanding (...) of the structure and function of emotional processes such as revealing which appraisals come first, how emotional processing endures both explicitly and implicitly, and that the resurgence of emotional processing may consist of either single or multiple processes.

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 (a) emotion-eliciting event (event duration and event (...) appraisal), (b) emotion itself (nature of the emotion component, nature of the emotion, and emotion intensity), and (c) emotion-experiencing person (dispositions and emotion regulatory actions). Initial evidence on the psychological and neural mechanisms that underlie their effects is discussed. (shrink)

Three experimental studies are reported in which we tested the prediction that negative emotion elicits the social sharing of the emotional experience. In two experiments, participants arrived at the laboratory with a friend and then viewed one of three film excerpts (nonemotional, moderate emotion, or intense emotion) alone. Afterwards, the participants who saw the film had an opportunity to interact with the friend and their conversation was recorded. In both experiments participants who had seen the intense emotion excerpt engaged in (...) significantly more social sharing than did participants in the other two conditions. A third experiment extended the investigation to social sharing in everyday life and replicated the previous results. Nonemotional explanations of the effects observed were also ruled out. Results are discussed in the context of the relation between emotional intensity and amount of social sharing. (shrink)

A full understanding of emotions and emotion characteristics can only be reached when their dynamic nature is taken into account. As such, a primary objective of the present study is to describe and account for variability in temporal profiles of experienced emotional intensity. Participants were asked to make detailed drawings of intensity profiles of recently experienced episodes of anger, sadness, joy and affection. Functional data analysis revealed three features that together accounted for 84% of the total variability: (i) steepness at (...) onset; (ii) skewness; and (iii) the number of peaks. Emotions differed with regard to the first two features, with the rise at onset being steeper for sadness and joy and affection being the most negatively skewed emotion under study. Individual differences regarding each of the three features were found, however, they did not strongly generalise across emotions. (shrink)

Purpose:This experimental cross-sectional research study examined the emotional reactivity and emotion regulation in preschool-age children who do (CWS) and do not stutter (CWNS) by assessing their psychophysiological response during rest and while viewing pictures from the International Affective Picture System (Lang et al.,2008).Method:Participants were 18 CWS (16 boys and two girls; mean age 4 years, 5 months) and 18 age- and gender-matched CWNS. Participants' psychophysiological responses were measured during two baselines and two picture viewing conditions. Skin conductance level (SCL) and (...) heart rate were measured to assess emotional reactivity. Respiratory sinus arrhythmia (RSA) was measured to assess emotional regulation. Participants' shyness and executive function were assessed via parent report and considered for their effects on participants' psychophysiological responses.Results:First, CWNS and CWS did not differ in their initial baseline SCL, heart rate, or RSA, but all participants had higher SCL and lower RSA in the second baseline, subsequent to the first challenge condition, compared to the first baseline. Second, during the challenge conditions, CWS did not differ from CWNS in their SCL, but showed a significantly higher heart rate than CWNS. Third, CWS exhibited a significantly lower RSA during the challenge conditions compared to CWNS. Lastly, the temperamental quality of shyness was associated with preschool-age children's SCL, such that participants who were rated higher in shyness had a higher SCL during the challenge conditions. Participants' executive function had a marginally significant effect on the RSA, such that the participants who had higher executive function composite scores exhibited lower RSA during the challenge conditions.Conclusions:Our findings suggest that CWS and CWNS did not differ in their emotional reactivity and emotional regulation abilities at rest. During challenge conditions, however, CWS tended to be more emotionally reactive, as indicated by a higher heart rate, and also employed more emotional regulation, indexed by a greater decrease in RSA, compared to CWNS. Preschool-age children's behavior is largely dominated by reactivity, but there is the emergence of regulation, which can help children adjust to various contextual demands. For CWS who are more emotionally reactive, regulatory skills may be particularly critical to their prognosis and treatment. (shrink)

This study explored a dimensional approach to vocal expression of emotion. Actors vocally portrayed emotions (anger, disgust, fear, happiness, sadness) with weak and strong emotion intensity. Listeners (30 university students and 6 speech experts) rated each portrayal on four emotion dimensions (activation, valence, potency, emotion intensity). The portrayals were also acoustically analysed with respect to 20 vocal cues (e.g., speech rate, voice intensity, fundamental frequency, spectral energy distribution). The results showed that: (a) there were distinct patterns of ratings of activation, (...) valence, and potency for the different emotions; (b) all four emotion dimensions were correlated with several vocal cues; (c) listeners' ratings could be successfully predicted from the vocal cues for all dimensions except valence; and (d) the intensity dimension was positively correlated with the activation dimension in the listeners' ratings.
