Friend or foe? Postdivorce hostility among recently divorced individuals

High levels of hostility often occur during and postdivorce and may significantly affect the quality of life, parent–child relationships, and social functioning of divorcees. Moreover, hostility may predict aggressive and violent behavior. This study sought to (a) compare average general hostility levels of a large sample of Danish divorcees to the norms of the general adult Danish population, (b) compare general hostility levels between male and female divorcees, and (c) investigate the explanatory value of various sociodemographic and divorce-related factors on postdivorce general hostility and whether these factors differ across gender. Cross-sectional baseline data (N = 1,856) from a larger randomized controlled trial study was used in this study. Normative data from a general sample of Danish adults (N = 2,040) was used for comparisons of hostility levels between our study sample and the Danish background population. This study found that male and female divorcees did not report significantly different hostility levels. However, participants reported significantly higher hostility levels postdivorce than the comparative Danish norm sample. Significant predictors of postdivorce hostility were lower age, lower educational level, infidelity as a reason for divorce, higher degree of postdivorce conflict, worse communication with the former spouse, the former spouse as the initiator of the divorce, and new partner status with neither divorcees having a new partner, or only the former spouse having a new partner. The predictive strength of the factors did not differ across gender. The findings may be especially relevant for interventions targeting problematic outcomes postdivorce (e.g., preventing aggressive behavior).     

Comparing negative emotion differentiation in young and older individuals: A picture-based study

Life span theories suggest that emotional experiences become more complex (i.e., nuanced and differentiated) with age. Theoretically, the cause of this increased complexity has been proposed to be age-related changes in life contexts such as goals and daily stressors. Consequently, age may not affect emotional complexity in settings where the influence of age-specific life contexts is reduced. However, this hypothesis has yet to be explored. In the present study, we investigated one aspect of emotional complexity, namely emotion differentiation. Extending previous research, we assessed age-group differences in negative emotion differentiation between young and older adults in a controlled experimental setting. A sample of 114 young and 132 older adults rated their emotional response to 34 negative pictures according to intensity of four negative emotions. Based on these ratings, two indicators of emotion differentiation were calculated. The results revealed no significant age-group differences in negative emotion differentiation. The findings indicate stability in negative emotion differentiation with increasing age when the influence of life context is reduced. The findings are consistent with life span theories suggesting that developmental changes in emotional complexity occur largely as a result of age-related changes in life contexts rather than more stable age-related changes in individual characteristics.

The Behavioral Immune System Shapes Partisan Preferences in Modern Democracies: Disgust Sensitivity Predicts Voting for Socially Conservative Parties

While there is growing interest in the relationship between pathogen-avoidance motivations and partisanship, the extant findings remain contradictory and suffer from a number of methodological limitations related to measurement and internal and external validity. We address these limitations and marshal the most complete test to date of the relationship between the behavioral immune system and partisanship, as indexed by which party people identify with and vote for. Using a unique research design, including multiple well-powered, nationally representative samples from the United States and Denmark collected in election and nonelection contexts, our study is the first to establish in cross-national data a consistent, substantial, and replicable connection between deep-seated pathogen-avoidance motivations and socially conservative party preferences across multiple validated measures of individual differences in disgust sensitivity and using large representative samples. We explore the relative contribution of the pathogen-avoidance model and sexual strategies for accounting for this relationship.
