The associations of the Five Factor Model of personality with inflammatory biomarkers: A four-year prospective study

This study evaluated the associations of the Five Factor Model of personality with two inflammation biomarkers, C-reactive protein and fibrinogen, and the possible moderating effects of common health-related behaviors (physical activity and smoking) concurrently and over four years, while adjusting for socio-demographic and health status. Participants were individuals who underwent a health examination at two points of time, T1 (n = 1709) and T2 (n = 923), about four years apart. Regression analyses uncovered positive associations between Neuroticism and Extraversion with two inflammatory biomarkers at baseline (T1) and over time (T2) and increases in their levels over time. Additionally, a synergistic interaction of neuroticism and physical inactivity was associated with higher levels of inflammation biomarkers at both time periods. Openness was negatively associated with inflammation biomarkers at T1 and T2, but not with changes in their levels. No significant associations were found for Agreeableness and Conscientiousness. The results suggest that personality traits might be involved in the inflammatory process both concurrently and over time, and thus indicate a possible mechanism by which personality traits might influence health, especially cardiovascular disease risk.     

Prior Divergence: Do Researchers and Participants Share the Same Prior Probability Distributions?

Do participants bring their own priors to an experiment? If so, do they share the same priors as the researchers who design the experiment? In this article, we examine the extent to which self‐generated priors conform to experimenters’ expectations by explicitly asking participants to indicate their own priors in estimating the probability of a variety of events. We find in Study 1 that despite being instructed to follow a uniform distribution, participants appear to have used their own priors, which deviated from the given instructions. Using subjects’ own priors allows us to account better for their responses rather than merely to test the accuracy of their estimates. Implications for the study of judgment and decision making are discussed.     

Practicing Compassion Increases Happiness and Self-Esteem

The current study examined the effect of practicing compassion towards others over a 1 week period. Participants (N = 719) were recruited online, and were assigned to a compassionate action condition or a control condition which involved writing about an early memory. Multilevel modeling revealed that those in the compassionate action condition showed sustained gains in happiness (SHI; Seligman et al. in Am Psychol 60:410–421, 2005) and self-esteem (RSES; Rosenberg in Society and the adolescent self-image. Princeton University Press, Princeton, 1965) over 6 months, relative to those in the control condition. Furthermore, a multiple regression indicated that anxiously attached individuals (ECR; Brennan et al. 1998) in the compassionate action condition reported greater decreases in depressive symptoms following the exercise period. These results suggest that practicing compassion can provide lasting improvements in happiness and selfesteem, and may be beneficial for anxious individuals in the short run.     

Question production in agrammatism: the tree pruning hypothesis

This study investigated question production in agrammatic aphasia, focusing on the comparison between Wh questions and yes/no questions and on the interaction between the question production deficit and language-specific properties. A total of 16 agrammatic aphasics (13 Hebrew speakers, 2 Palestinian Arabic speakers, and 1 English speaker) participated in the study, which included sentence elicitation and repetition tasks. In addition, the patients' spontaneous speech, containing 2272 utterances, was analyzed. The main findings were that Hebrew- and Arabic-speaking agrammatics encounter severe difficulties in Wh question production but retain the ability to produce yes/no questions. English-speaking agrammatics do not show this dissociation and can form neither Wh nor yes/no questions. These dissociations as well as the error pattern, are explained by reference to the Tree Pruning Hypothesis, according to which the highest nodes of the syntactic tree, which are required for Wh questions in Hebrew, Arabic, and English and for yes/no questions in English, are impaired or inaccessible in agrammatism.

On the aggregation across subjects in analyzing individual choice behavior

Authors dealing with models of individual choice behavior often point out the pitfalls of using group data to test such models. However, it is possible to derive properties of the choice behavior of the population based on these models of individual choice behavior. The present paper develops a procedure for the aggregation of choice data which takes into account individual differences. The utility of using aggregated choice data and the properties of the present procedure in comparison to other methods which utilized group data in analyzing choice behavior are discussed.     

Complex Collective Trauma Following a Terror Attack in a Small Community: A Systemic Analysis of Community Voices and Psychosocial Interventions

In this ethnographic study, data were collected four months, one year, and three years following a terror attack on civilians in a small Israeli community. The data included protocols of meetings of the intervention team, informal and formal interviews, and follow-up telephone interviews with local leaders and psychosocial professionals who worked with individuals, families, and groups in the community. Content analysis of field notes and interviews led to the elaboration of the theoretical construct “complex collective trauma.” The analysis of the community voices and psychosocial interventions indicated the importance of action-oriented, meaning-making community projects and memorials, screening and government-funded short-term trauma therapy, mapping interlocking circles of vulnerability, and an integrated clinical-community model coordinated long-term (one year) by an outside professional.     

The Contribution of Maternal ADHD Symptomatology,Maternal DAT1, and Home Atmosphere to Child ADHD Symptomatology at 7 Years of Age

Children of mothers with attention-deficit/hyperactivity disorder (ADHD) have an increased genetic and environmental risk for ADHD. The unique and interactive contributions of a maternal dopamine receptor gene (DAT1), maternal ADHD symptoms (hyperactive- impulsive, inattentive), and home atmosphere to the prediction of ADHD symptoms (hyperactive- impulsive, inattentive) in 7- year-old boys (N = 96) were examined using data from a longitudinal study of familial risk for ADHD. During the first 6 months of the study, mothers and their spouses completed a questionnaire about the mother’s ADHD symptoms. Home atmosphere questionnaire data were collected 4 years later. At the 7-year assessment, mothers reported on their child’s ADHD symptoms. Negative home atmosphere was significantly associated with child hyperactive-impulsive and inattentive symptoms. Maternal inattentive symptoms were significantly correlated with both child symptom dimensions. Regression models, with child genotype and maternal education controlled, showed main effects for maternal inattentive symptoms, maternal DAT1 10/10 genotype, and home atmosphere in the prediction of child inattentive symptoms. Only home atmosphere predicted child hyperactive-impulsive symptoms. There was a significant home atmosphere x maternal hyperactive-impulsive symptoms interaction in the prediction of child hyperactive-impulsive symptoms. Boys with higher levels of symptoms came from homes characterized by higher levels of negative atmosphere and had mothers with higher levels of hyperactive-impulsive symptoms. There was also a trend (p = 0.075) for a maternal DAT1 x home atmosphere interaction. Boys with higher levels of inattentive symptoms came from homes with higher levels of negative atmosphere and had mothers with the homozygous 10/10 genotype. The maternal heterozygous 9/10 genotype did not predict child symptoms.
