Attentional and behavioural responses of spider fearfuls to virtual spiders

This study employed an immersed virtual environment (IVE) in the Nijmegen RIVERlab to study spider fearfuls’ attentional and motor reactions to virtual spiders. The participants were exposed to virtual spiders while completing an unrelated task, walking freely through a virtual museum. Compared to non-fearful controls, spider fearfuls showed an increase in state anxiety, they spent more time looking at spiders, and they exhibited spontaneous behavioural avoidance of spiders and visually similar objects. The results extend, and to some degree contradict, those of earlier studies with static pictures, and they speak to the usefulness of state-of-the-art IVEs in fundamental anxiety research.     

The Relation Between Appraised Mismatch and the Duration of Negative Emotions: Evidence for Universality

Emotions are processes that unfold over time. As a consequence, a better understanding of emotions can be reached only when their time‐related characteristics can be assessed and interpreted adequately. A central aspect in this regard is the duration of emotional experience. Previous studies have shown that an emotional experience can last anywhere from a couple of seconds up to several hours or longer. In this article, we examine to what extent specific appraisals of the eliciting event may account for variability in emotion duration and to what degree appraisal–duration relations are universal or culture specific. Participants in 37 countries were asked to recollect emotional episodes of fear, anger, sadness, disgust, shame and guilt. Subsequently, they were asked to report the duration of these episodes and to answer a number of questions regarding their appraisal of the emotion‐eliciting event. Multi‐level analyses revealed that negative emotions last especially long when the eliciting event and its consequences are perceived to be incongruent with the individual's goals, values and self‐ideal, creating a mismatch. These relations are largely universal, although evidence for some limited variability across countries is found as well. Copyright © 2013 European Association of Personality Psychology     

Improved Insight into and Prediction of Network Dynamics by Combining VAR and Dimension Reduction

To understand within-person psychological processes, one may fit VAR(1) models (or continuous-time variants thereof) to multivariate time series and display the VAR(1) coefficients as a network. This approach has two major problems. First, the contemporaneous correlations between the variables will frequently be substantial, yielding multicollinearity issues. In addition, the shared effects of the variables are not included in the network. Consequently, VAR(1) networks can be hard to interpret. Second, crossvalidation results show that the highly parametrized VAR(1) model is prone to overfitting. In this article, we compare the pros and cons of two potential solutions to both problems. The first is to impose a lasso penalty on the VAR(1) coefficients, setting some of them to zero. The second, which has not yet been pursued in psychological network analysis, uses principal component VAR(1) (termed PC-VAR(1)). In this approach, the variables are first reduced to a few principal components, which are rotated toward simple structure; then VAR(1) analysis (or a continuous-time analog) is applied to the rotated components. Reanalyzing the data of a single participant of the COGITO study, we show that PC-VAR(1) has the better predictive performance and that networks based on PC-VAR(1) clearly represent both the lagged and the contemporaneous variable relations.     

The Psychology of Gender Differences in Religion: A Review of Empirical Research

This paper presents, discusses and evaluates empirical studies concerned with gender differences in religion. Within the psychology of religion two main groups of theories have been advanced to account for gender differences in religiosity. The first group of theories concentrates on social or contextual influences which shape different responses to religion among men and women. This group may be divided into two categories: gender role socialisation theories and structural location theories. The second group of theories concentrates on personal or individual psychological characteristics which differentiate between men and women. This group may be divided into three categories: depth psychology theories, personality theories and gender orientation theories. It is concluded that gender orientation theories provide the most fruitful source for further research.     

Validation of a new multidimensional health locus of control scale (form c) in asthma research

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.     

Emotion processing and regulation in women with morbid obesity who apply for bariatric surgery

Emotional eating, the tendency to eat when experiencing negative affect, is prevalent in morbid obesity and may indicate that ways to deal with emotions are disturbed. Our aim was to compare emotion processing and regulation between 102 women with morbid obesity who apply for bariatric surgery and 102 women from the general population (control group) and to examine in the group with morbid obesity the association of emotion processing and regulation with emotional eating. The group with morbid obesity reported higher scores on difficulty identifying feelings (alexithymia, p?=?0.002) and suppression of emotions (p?=?0.003) than the control group. In the women with morbid obesity, more negative affect and a higher difficulty identifying feelings were correlated with more emotional eating (r?=?0.36 and r?=?0.35, p?<?0.001). Our study suggests that negative emotions and unhealthy emotion processing may play a role in emotional eating, and it indicates the possible relevance of emotion processing and emotional regulation as initiating or perpetuating mechanisms in morbid obesity.     

Validating Measures of Psychological Well-being by Contrasting Samples Employed in Hazardous and Less Hazardous Work

The study investigated whether differences between contrasting groups reflect significant differences in psychological well-being scores. Membership of hazardous vs. less hazardous occupations in the same profession served as proxy measures of well-being. Antonovsky's Sense of Coherence (SOC), Block & Kremen's Ego-resiliency, and Goldberg's Emotional Stability scales were validated. Study 1 compared mine rescue team members and ordinary miners (n = 34, 41) and Study 2 police special task force members and regular officers (n = 43, 41). In Study 1, SOC and job satisfaction predicted group membership. In Study 2, satisfaction with life and extraversion scales predicted group membership, as did SOC in a secondary analysis. The SOC scale could predict psychological well-being in hazardous work settings.
