Do emotions have distinct vocal profiles? A study of idiographic patterns of expression

Research on vocal expressions of emotion indicates that persons can identify emotions from voice with relatively high accuracy rates. In addition, fairly consistent vocal profiles for specific emotions have been identified. However, important methodological issues remain to be addressed. In this paper, we address the issue of whether there are individual differences in the manner in which particular emotions may be expressed vocally and whether trained speakers’ portrayals of emotion are in some sense superior to untrained speakers’ portrayals. Consistent support was found for differences across speakers in the manner in which they expressed the same emotions. No accompanying relationship was found between differences in expression and accuracy of identification of those expressions. Little evidence for the superiority of trained speakers was found. Implications of these findings for future studies of vocal expressions of emotion, as well as our understanding of emotions in general, are discussed.     

Mating Behavior in the Japanese Beetle,Popillia Japonica Newm

The Investment Model (IM; Rusbult, 1980, 1983) has been widely used to study the development and maintenance of romantic relationships. Its components—satisfaction, quality of alternatives, investment size and commitment—are operationalized in the Investment Model Scale (IMS; Rusbult, Martz, &; Agnew, 1998). Given its importance for personal relationships literature, this article presents the adaptation and validation of the IMS to Portugal, and the development and validation of a shorter version, the IMS-S. A confirmatory factor analysis replicates the IMS's original four factors structure. A similar structure was found for the IMS-S. For both versions, results show the instruments to have validity and good reliability. Results are discussed considering the scales’ importance for studying romantic relationships.     

Stages of change in fruit intake: A longitudinal examination of stability,stage transitions and transition profiles

The present study examined stability and transitions in Transtheoretical stages of change for fruit intake in an adult cohort of 735 individuals not exposed to a planned intervention. Six assessments took place within a four-month period with varying time intervals using electronic questionnaires, measuring fruit intake, stage of change and demographic characteristics. Precontemplation and maintenance were the most stable stages of change, while preparation was the least stable. Longer time intervals showed lower stability, but frequent stage transitions also occurred in shorter time intervals. Seven transition profiles were distinguished. Sequences within transition profiles mostly showed stage transitions to adjacent stages, independent of the interval duration. Differences in fruit intake, age, level of education and ethnicity were found between different transition profiles. Stability rates and most transition sequences largely support the Transtheoretical Model. Results indicating potential deviations from the model, e.g. short-term stage instability and stage transition profiles not in accordance with the Transtheoretical Model are discussed.     

Occupational Stress and Wellness Among Italian Secondary School Teachers

As a part of a larger cross-cultural investigation (Euroteach) which involves 11 European countries and 2 182 secondary school teachers, two were the aims of the present study: (1) to examine the relationship between job conditions and wellness/health outcomes on a group of 169 Italian secondary school teachers, by using the Job Demand-Control-Support (JDCS) Model (Karasek and Theorell, <citeref rid="bib24">1990</citeref>); (2) to analyse the differences with other European countries in the light of specific cultural differences. Controlling for age and gender, results of hierarchical regression indicated that job control and social support combine in different additive patterns with job demands to explain the well-being outcomes (job satisfaction, emotional exhaustion, depersonalisation, somatic complaints). The predictor's linearity check indicated that the job demands variable is curvilinearly associated both with emotional exhaustion ( p<0.005) and with somatic symptoms ( p<0.01). As compared to the average of the other European countries, on the positive side, the Italian teachers manifest both a higher degree of personal accomplishment and a lesser degree of depersonalisation; on the other hand, they claim a lesser degree of social support and a higher degree of somatic complaints.     

The Job Demand-Control-Social Support Model and Wellness/Health Outcomes: A European Study

The EUROTEACH study which is reported here, comprised 2796 secondary school teachers from 13 European countries. The study firstly aimed at testing an extended Job Demand-Control-Social support (JDCS) model and checking its gender specificity. While this study failed to provide evidence for the buffer hypothesis derived from the JDCS-model, the strain hypothesis was mostly supported. Additional job conditions tested in this study proved to be important predictors of the outcome variables (emotional exhaustion, depersonalisation, personal accomplishment, somatic complaints and job satisfaction) and standard of living indicators also added explained variance in these outcomes. The study proved that the JDCS model cannot be called a male model. Secondly the study looked at the comparability of 3 European regions (South, West, East). Apart from important regional differences in job conditions, standard of living indicators and outcomes, the most important finding is that the JDCS model explains most variance in outcome variables in Western Europe, and the least in Eastern Europe, and thus seems to suffer from a Western bias.     

A Meta-Analytic Review of the Common-Sense Model of Illness Representations

A meta-analysis of empirical studies ( N = 45) adopting Leventhal, Meyer and Nerenz's (1980) Common Sense Model (CSM) of illness representations is presented. The average corrected intercorrelation matrix for the sample of studies showed that the CSM illness cognition dimensions of consequences, control/cure, identity and timeline followed a logical pattern supporting their construct and discriminant validity across illness types. A content analysis classified coping strategies into seven distinctive categories and health outcomes into six categories. Examining the average corrected correlation coefficients across the studies revealed that perceptions of a strong illness identity were significantly and positively related to the use of coping strategies of avoidance and emotion expression. In addition, perceived controllability of the illness was significantly associated with cognitive reappraisal, expressing emotions and problem-focused coping strategies. Perceptions of the illness as highly symptomatic, having a chronic timeline and serious consequences was significantly correlated with avoidance and expressing emotions coping strategies. Further, perceptions that the illness was curable/controllable was significantly and positively related to the adaptive outcomes of psychological well-being, social functioning and vitality and negatively related to psychological distress and disease state. Conversely, illness consequences, timeline and identity exhibited significant, negative relationships with psychological well being, role and social functioning and vitality. The analyses provide evidence for theoretically predictable relations between illness cognitions, coping and outcomes across studies.     

Anchoring Bullying and Victimization in Children Within a Five‐Factor Model‐Based Person‐Centred Framework

Although researchers have begun to explore bullying and victimization problems from a personality perspective, more work is needed on the particular personality constellations of children and adolescents who are vulnerable to victimization or prone to bullying. The principal research goal of the present study was to anchor the robust four‐group classification of bullying and victimization (i.e. bullies, victims, bully/victims and uninvolved children) within the Five‐Factor Model‐based person‐centred framework in primary school children (N = 660), controlling for gender. We found four distinct personality types in middle childhood: a mixed type, an undercontrolled type, a moderate type and a resilient type. In line with expectations, we found that a resilient personality profile protected children and adolescents against victimization and that children and adolescents with an undercontrolled or mixed personality profile were at increased risk to be bully/victims, rather than uninvolved in bully problems or victimization, compared with children with a moderate personality profile. Implications for theory and practice are discussed. Copyright © 2013 John Wiley & Sons, Ltd.
