The construct and criterion validity of emotional intelligence and its potential utility for management studies

In this study, the authors reviewed the definition of emotional intelligence (EI) and argued that El is conceptually distinct from personality. In Study 1, the authors showed that EI was related to yet distinct from personality dimensions and that it had incremental predictive power on life satisfaction. The authors examined the construct validity of self-reports and others' ratings of EI using two samples in Study 2. In a student sample, parents' ratings explained additional variance in the students' life satisfaction and feelings of powerlessness after controlling for the Big Five personality dimensions. In the work sample, peer ratings were found to be significant predictors of job performance ratings provided by supervisors after controlling for the Big Five personality dimensions. Other implications for future research on EI are discussed.     

Predicting traumatic stress using emotional intelligence

The study investigated whether emotional intelligence (EI) can predict how individuals respond to traumatic experiences. A random sample of 414 participants (181 male, 233 female) were administered a measure of EI along with the Impact of Event Scale--revised [IES-R; Weiss, D. S. & Marmar, C. R. (1997). The Impact of Events Scale--revised. In J.P. Wilson & T.M. Keane (Eds.), Assessing psychological trauma and PTSD (pp. 399-411). New York: Guilford Press], and the monitoring and blunting questionnaire [MBQ, Anxiety Stress Coping 7 (1994) 53]. The results showed that participants with higher NEIS scores report fewer psychological symptoms relating to their traumatic experiences, that monitors are more likely to have higher NEIS scores than blunters. Traumatic events had a greater impact on females than males, and males had higher EI than females. The implications of these findings for using EI as a predictor for individuals who may experience traumatic stress are discussed.     

The effect of "stress hormones" on emotional sensitivity]

Stress is associated with an increased secretion of hormones from the hypothalamus-pituitary-adrenal-axis (HPA-axis). Once released into the blood stream they induce a number of adaptive changes that may also have pertinence to brain functions, resulting, for example in alterations of mood. To provide evidence for a mediation of mood changes by stress related hormone secretion, the influences of a short-term administration of hormones of the HPA-axis on mood and activation were assessed in a total of 182 healthy men (aged between 18 and 34 years in 7 experiments). Effects of intravenously administered hormones on self-perceived mood and activation were assessed by a standardized adjective checklist (Eigenschaftsw?rterliste) in placebo-controlled, double-blind experiments during rest. Results indicated no effects following corticotropin releasing-hormone or cholecystokinin, but specific effects resulted after vasopressin, oxytocin, ACTH-related hormones, and cortisol. Vasopressin and oxytocin increased activation and attenuated arousal and anger, ACTH-related hormones increased sensitivity and diminished extraversion, while cortisol increased activation and concentration. It is concluded that hormones of the HPA-axis specifically affect mood and activation. The pattern of hormonal changes in mood may have adaptive functions by preparing for behavioral and cognitive coping with stress.     

The effect of emotional stress on involuntary and voluntary conscious memories

Clinical theories of post-traumatic stress disorder often claim that intrusive (involuntary) memories favour emotionally stressful material and that these memories come with more sensory imagery and emotional reliving compared to voluntary memories. However, these assumptions have not been verified experimentally. Here we obtained recordings of emotional reactions to aversive pictures at the time of encoding, as well as records of involuntary and voluntary memories of these pictures in a subsequent diary study. A comparison of individual ratings, obtained during encoding, of pictures recalled involuntarily and voluntarily showed that emotional stress at encoding increased overall accessibility, independent of whether recall was voluntary or involuntary. However at the time of recall, voluntary memories scored higher on narrative content and on measures of imagery. The findings are compatible with research on emotion and memory in general, but challenge clinical claims of differential involuntary versus voluntary access to emotionally stressful events.     

Information-processing predictors of emotional response to stress

Information-processing biases of attention toward and interpretation of threat were measured in 29 undergraduates during a period of low academic stress. During a later period of high academic stress, participants were interviewed about their emotional response: anxious and depressive symptoms, and positive and negative affect. Anxiety symptoms at follow-up were predicted by attention to masked threat stimuli, while negative affect at follow-up was predicted by interpretation of ambiguous items as threatening. Results suggest that although attentional processes appears to play a role in the development of anxiety symptoms, the experience of negative affect during stress may be regulated by more interpretive processes.     

The impact of stress on neutral and emotional aspects of episodic memory

The present experiment demonstrates that exposure to a significant psychological stressor (administered before watching a slide show) preserves or even enhances memory for emotional aspects of an event, and simultaneously disrupts memory for non-emotional aspects of the same event. Stress exposure also disrupted memory for information that was visually and thematically central to the event depicted in the slide show. Memory for peripheral information, on the other hand, was unaffected by stress. These results are consistent with theories invoking differential effects of stress on brain systems responsible for encoding and retrieving emotional memories (the amygdala) and non-emotional memories (e.g., the hippocampal formation), and inconsistent with the view that memories formed under high levels of stress are qualitatively the same as those formed under ordinary emotional circumstances. These data, which are also consistent with results obtained in a number of studies using animals and humans, have implications for the traumatic memory debate and theories regarding human memory.     

The influence of stress hormones on emotional memory: relevance for psychopathology

Substantial progress within recent years has led to a better understanding of the impact of stress on emotional memory. These effects are of relevance for understanding and treating psychopathology. The present selective review describes how emotional memory is modulated through stress hormones. Acute as well as chronic effects are discussed and information from rodent models is compared to human experimental studies and clinical observations. Finally, the relevance of these findings for emotional memory disturbances in psychiatric disorders is exemplified by discussions on neuroendocrine alterations in depression, post traumatic stress disorder and phobias.     

The role of emotion control and emotional rumination in stress management training

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.     

Explaining the protective effect of trait emotional intelligence regarding occupational stress: Exploration of emotional labour processes

This paper aims at understanding the processes explaining the protective effect of trait emotional intelligence (trait EI) regarding occupational stress. The present study focuses on a widespread occupational stressor: emotional labour (EL). EL refers to the act of managing emotions and emotional expressions in order to be consistent with organizational ‘display rules’, defined as the organizationally required emotions during interpersonal service transactions. As these display rules interact with employees spontaneous feelings, they regularly induce a clash between inner/real and required feelings. Different strategies exist to cope with this dissonance, with either beneficial or deleterious outcomes regarding psychological and physical health. The hypothesis underlying this study was that individuals varying in the level of trait EI would use different EL strategies, with different outcomes in terms of burnout and somatic complaints. Globally, the results showed that, when confronted with emotional labour, high trait EI individuals experience lower levels of burnout and somatic complaints, and this effect was found to be mediated by the choice of emotional labour strategies. Implications of these results for research, theory and practice are discussed.     

The effects of metabolic stress and vagotomy on emotional learning in an animal model of anxiety

The aim of the present study is to evaluate the role of the blood glucose (BG) level in emotional learning in the elevated plus maze (EPM), an animal model of anxiety. In Experiment 1, male Wistar rats were submitted to different EPM trial lengths (1- or 5-min). Blood samples were withdrawn before and after the maze exploration, through a polyethylene cannula chronically implanted into the jugular vein. In Experiment 2, the animals received either saline or 2-deoxy-D-glucose, a glucoprivic drug (2-DG, 250 or 500 mg kg(-1)) by i.p. route, 30 min before a 5-min EPM exposure and were retested in the maze (Trial1/Trial2 EPM procedure) 24 h later. In an independent group of rats, blood samples were withdrawn 0, 5, 15, and 30 min after 2-DG administration, through the jugular vein, to determine BG. In Experiment 3, the animals underwent a vagotomy and were tested in a Trial1/Trial2 EPM procedure four weeks later. The results showed that rats exploring the EPM for 5 min displayed increased fear and higher hyperglycemia than those exploring the EPM for 1 min. In addition, rats submitted to 5-min EPM Trial1 length displayed higher level of fear on Trial2, as well as higher percentage of shortening of the %Open arm entries and %Open arm time from Trial1 to Trial2, which characterizes the occurrence of emotional learning. In contrast, rats previously vagotomized or treated with 2-DG (500 mg kg(-1)) showed the same level of fear on both EPM trials and a low percentage of shortening, from Trial1 to Trial2, of the %Open arm entries and %Open arm time, indicating poor emotional learning. The data is discussed regarding the role of glycaemia in emotional learning in the EPM.     

New legal rights related to emotional stress in the workplace

This article reviews the new legal rights that employees can exercise due to their experience of excessive emotional stress in the workplace. Three types of worker stress insurance claims are delineated: mental-physical, physical-mental, and mental-mental. Reasons for the expected increase in these types of claims are forwarded.     

Spirituality moderates the effect of stress on emotional and physical adjustment

This study examined the relationship of spirituality with emotional and physical adjustment to daily stress. One hundred and thirteen college students completed questionnaire measures of spirituality, daily stress, affect, and physical symptoms at two times one month apart. The results showed that spirituality buffered the adverse effect of stress on adjustment, controlling for the use of various coping strategies. The findings have implications for developing prevention programs to improve people's coping skills by incorporating greater emphasis on spirituality.     

Effects of anxiety sensitivity on emotional response to a stress task

The purpose of this investigation was to further define the role of anxiety sensitivity, in relation to physiological arousal and the cognitive perception of anxiousness, as a determinant of anxiety. One hundred and thirty-two undergraduates at an urban university served as subjects. Two physiological measures of arousal and two cognitive measures of anxiety were used following an anxiety inducing task (mental arithmetic). The general expectation, which was supported, was that individual differences in anxiety sensitivity levels are more closely related to subjects' reported anxiousness in stressful conditions than are the actual physiological changes. Additionally, anxiety sensitivity was related to poststress levels of anxiety whereas trait anxiety was only related to pre- and postrelaxation levels of anxiety. Implications of the findings are addressed.     

The influence of emotional conditions on imilarity estimations of emotional terms

Abstract.— Twenty-four male university students made similarity estimations whilst under the influence of five strongly contrasting emotional inducing situations and in a neutral situation. Intra- and interindividual comparisons between the results indicate that a high degree of stability was maintained by each individual over time whereas differences appeared between individuals. The results suggest that subjects are well able to produce about the same result in spite of heightened levels of emotional state.
