The scholar’s best friend: research trends in dog cognitive and behavioral studies

Animal Cognition - In recent decades, cognitive and behavioral knowledge in dogs seems to have developed considerably, as deduced from the published peer-reviewed articles. However, to date, the...     

Factors Associated with Providers’ Work Engagement and Burnout in Homeless Services: A Cross‐national Study

The complexity of homeless service users’ characteristics and the contextual challenges faced by services can make the experience of working with people in homelessness stressful and can put providers’ well‐being at risk. In the current study, we investigated the association between service characteristics (i.e., the availability of training and supervision and the capability‐fostering approach) and social service providers’ work engagement and burnout. The study involved 497 social service providers working in homeless services in eight different European countries (62% women; mean age = 40.73, SD = 10.45) and was part of the Horizon 2020 European study “Homelessness as Unfairness (HOME_EU).” Using hierarchical linear modeling (HLM), findings showed that the availability of training and supervision were positively associated with providers’ work engagement and negatively associated with burnout. However, results varied based on the perceived usefulness of the training and supervision provided within the service and the specific outcome considered. The most consistent finding was the association between the degree to which a service promotes users’ capabilities and all the aspects of providers’ well‐being analyzed. Results are discussed in relation to their implications for how configuration of homeless services can promote social service providers’ well‐being and high‐quality care.     

The role of body image and self‐perception in anorexia nervosa: the neuroimaging perspective

Anorexia nervosa is a severe psychiatric illness characterized by intense fear of gaining weight, relentless pursuit of thinness, deep concerns about food and a pervasive disturbance of body image. Functional magnetic resonance imaging tries to shed light on the neurobiological underpinnings of anorexia nervosa. This review aims to evaluate the empirical neuroimaging literature about self‐perception in anorexia nervosa. This narrative review summarizes a number of task‐based and resting‐state functional magnetic resonance imaging studies in anorexia nervosa about body image and self‐perception. The articles listed in references were searched using electronic databases (PubMed and Google Scholar) from 1990 to February 2016 using specific key words. All studies were reviewed with regard to their quality and eligibility for the review. Differences in brain activity were observed using body image perception and body size estimation tasks showing significant modifications in activity of specific brain areas (extrastriate body area, fusiform body area, inferior parietal lobule). Recent studies highlighted the role of emotions and self‐perception in anorexia nervosa and their neural substrate involving resting‐state networks and particularly frontal and posterior midline cortical structures within default mode network and insula. These findings open new horizons to understand the neural substrate of anorexia nervosa.     

The perceptions of the causes of cardiac diseases: a taxonomy

Objective: This study verifies whether the open-ended question of the B-IPQ can collect causal attributions of patients with cardiac diseases, define the more frequent causal attributions reported, classify them and describe the relation between the classification of the causes and patients’ characteristics.

Design: A group of 2011 patients with cardiac diseases was recruited during the first week of cardiac rehabilitation.

Primary outcome measures: Every participant filled in the B-IPQ and the HADS. The qualitative and quantitative analyses of the text using T-LAB identified the most frequent causal attributions and their co-occurrences.

Results: Among the patients, 26% did not recognise any causal attribution. The likelihood that the patients did not provide an answer was increased in older patients, females, patients with lower levels of education and higher levels of depression. Smoking and stress emerged as the most important attributions, followed by genetics, metabolic syndrome, work and nutrition. Four thematic clusters were identified: ‘work and stress’, ‘metabolic syndrome and hypertension’, ‘displeasures and body care’ and ‘heredity and other related diseases’.

Conclusions: This study suggests a classification of the causal attributions in patients with cardiac diseases and identifies thematic patterns and unknown attributions. The themes identified can serve as categories for future closed-ended questions.     

Goodness of regularity in dot patterns: global symmetry, local symmetry, and their interactions

Goodness is a classic Gestalt notion defined as salience or perceptual strength of a given pattern. All operational models of goodness have assigned a central role to mirror symmetry but not much attention has been paid to the distinction between global and local mirror symmetry, and their possible interactions. We designed eight different types of dot patterns (all consisting of 80 dots), combining different numbers (0, 1, and 2) and relative orientations (parallel or orthogonal to each other) of local and global axes of symmetry (affecting 50% or 100% of the dots, respectively) at different absolute orientations (vertical and horizontal). Each of 640 trials consisted of a short presentation of a new dot pattern, which subjects had to classify as regular or random. We hypothesised that the overall goodness of patterns is not the simple sum of the amount of regularity present in them but depends on the cooperation and competition between symmetries. The results confirmed our hypothesis, showing that performance in this regularity-detection task did not increase in a linear way when some symmetries were added to other symmetries.     

How New Knowledge About Parenting Reveals the Neurobiological Implications of Intersubjectivity: A Conceptual Synthesis of Recent Research

Observations of early mother–infant interactions have shown that intersubjectivity is a primary motivation and have underscored the importance of maternal competencies in this development. In our paper we propose a conceptual overview of the different perspectives according to which parental caregiving has been formulated. Psychoanalytical theory has fundamentally promoted the exploration of maternal and paternal intrapsychic constellation, by stressing the role of unconscious processes in parental attitude as well as in infant development. In contrast with psychoanalytical theory, the conceptual framework of attachment has mostly considered real interactions between parents and infant, underlining parental abilities in providing the infant with a secure base. Finally, infant research has explored the complexity of communicative system between parents and infants, which appears already active from the birth of the baby. Recently, these different viewpoints have been broadened by neurobiological research, which has begun to explore maternal brain functioning and structure, by means of new scientific instruments such as fMRI techniques. From these perspectives, we provide an overview of motherhood, underlining both neurobiological and psychological transformations, which begin from pregnancy and run through the first year of the infant, when the mother–infant intersubjective matrix is built. This matrix influences the construction of the infant's Self and support the development of the sense of “we,” a sort of connective net, which ties the baby to parents, letting him feel as a part of the familiar world.     

The Relationship Between Levels of Guilt in Thematic Stories and Unsocialized Behavior

Many previous studies on the relationship between inhibition of expression of hostility in thematic stories have focused on the severity of the punishment rather than the quality of the guilt expressed. Using a more subtle approach, it was found that an increase in the level and quality of guilt expressed in TAT stories was significantly associated with a reduction in unsocialized behavior. The results suggest that an analysis of guilt along dimensions of internalization, the concern for others, and the desire to change offers a way of dealing with thematic productions that is more consistent with our clinical observations and understanding.     

Ordeal by Fire: The Tragedy of the Solar Temple

On October 4th and 5th, 1994, fifty-three people were found dead in Switzerland and in Canada. Their bodies—some showing signs of violence suffered before the fires—were found in the incinerated centres of a neo-Templar movement called originally International Order of Chivalry Solar Tradition or, for short, Solar Tradition, and after 1990-91 Order of the Solar Temple. The movement is part of one of several currents which as a whole compose the universe of the contemporary occult-esoteric movements, the neo-Templar tradition. In this paper I propose to trace, first of all, the history of the neo-Templar tradition, then that of the Solar Temple, relating the essential information on the tragedy of October 1994, and finally suggesting some possible interpretations.
