Response to bitter substances in primates: Roles of diet tendency and weaning age

In primates, the perception of bitter taste may be an essential mechanism for avoiding the ingestion of bitter, and often toxic, substances. Bitterness sensitivity varies across the different primate species and, for bitter thioure substances (e.g., phenylthiocarbamide—PTC), within species. Primates respond to bitterness by displaying aversive affective reactions, and whether these serve for conspecifics as information on the taste of food is still unclear. The aim of this study was to investigate the response to two bitter substances (quinine and PTC) in 11 primate species (N = 29 individuals) hosted at the Ménagerie du Jardin des Plantes, in relation to their main diet tendency and weaning age. We tested primate reactions to bitterness with a two-bottle method. The study individuals showed a strong aversion to bitter taste, minimizing consumption of both bitter solutions. All of the individuals were PTC-taster phenotypes, but the degrees of sensitivity to PTC varied among the individuals. Across-species comparisons revealed that whereas the degree of frugivory of the species had a negative effect on the consumption of bitter solutions by the individuals, a later weaning age seems to be a better predictor for the occurrence of aversive affective reactions. Although the low sample size does not allow for excluding interindividual variability, our results support the hypothesis that affective reactions to bitterness may be trustworthy information for conspecifics during the learning process. Thus, the evolution of the appropriate perceiver systems to convert affective displays into true affective signals could be a shared trait among human and nonhuman primates.     

Adolescents with congenital heart disease: psychopathological implications

The psychopathological risks of congenital heart disease in adolescence are described. The emotional development of adolescents with cardiopathy is discussed, including distortions in body image and separation-individuation issues. The consequences of cyanotic and acyanotic cardiopathies for intellectual functioning are noted, and the impact of congenital heart disease on interactions with parents and siblings is presented. Psychopathological implications of heart transplant are also reviewed.

An investigation of an Expanded Encapsulate Model of Social Identity in Collective Action (EMSICA) including perception of threat and intergroup contact to understand support for Islamist terrorism in Indonesia

Although there have been many empirical studies of terrorism within the psychology literature, relatively few studies have theorized terrorism from the perspective of collective action theory. The present study aimed to understand factors that predict support for Islamist terrorism by using the Encapsulate Model of Social Identity in Collective Action (EMSICA) perspective. To extend previous studies, we added perception of threat and intergroup contact to the model. A correlational study using 66 terrorism detainees in Indonesia as participants found solid support for our expanded EMSICA. The models extending EMSICA with perception of threat and quantity of contact as predictors had improved fit indices and explained more variance in the dependent variable support for Islamist terrorism, as compared to the standard model. Social identity had a significant direct effect on support for Islamist terrorism and mediated the effect of intergroup contact, perception of threat, perceived injustice, and group efficacy on support for Islamist terrorism.     

Injury characteristics across functional classes of self-injurious behavior

Self-injurious behavior (SIB) is inherently problematic because it can lead to injuries, including those that are quite severe and may result in loss of function or permanent disfigurement. The current study replicated and extended Rooker et al. (2018) by classifying the physical characteristics of injuries across groups of individuals with automatically maintained SIB (ASIB Subtypes 2 and 3) and socially maintained SIB. Individuals with Subtype 2 ASIB had the most frequent and severe injuries. Further, an inverse relation was found between the level of differentiation in the functional analysis and the number of injuries across groups. Studying the response products of SIB (the injuries) documents the risks associated with SIB, justifies the need for research and the intensive intervention, and advances knowledge of SIB. Additional research is needed to replicate these findings, and determine the variables that produce different characteristics of injury secondary to SIB.     

Differences in Dropout Rates Among Individual, Couple, and Family Therapy Clients

The premature dropout of clients from therapy is an inefficient expenditure of mental health resources. This study examined differences in dropout rates among individual, couple, and family therapy clients. Data came from archived records at a marriage and family therapy clinic at a university in the United States. Results indicated that there were no significant differences in dropout rates, despite the use of multiple measures of dropout. Thus, from a mental health services perspective, administrators and clinicians can expect that dropout rates will remain fairly consistent across treatment modalities.     

On the nature of intuitive and delusional thought: Its implications in clinical work with psychotic patients

The author tries to differentiate intuitive imagination from delusional imagination and hypothesises that psychosis alters the system of intuitive thinking, which consequently cannot develop in a dynamic and selective way. Scholars of different disciplines, far removed from psychoanalysis, such as Einstein, Hadamard or Poincar, believe that intuitive thinking works in the unconscious by means of hidden processes, which permit a creative meeting of ideas. Thanks to Bion's work, psychoanalysts have begun to understand that waking thinking is unconsciously intertwined with dream‐work. The delusional construction is similar to a dreamlike sensorial production but, unlike a real dream, it remains in the waking memory and creates characters which live independently of the ‘dreamer's’ awareness. It is a dream that never ends. On the contrary, the real dream disappears when it has brought its communicative task to an end. In the analysis of psychotic patients it is very important to analyse the delusional imagination which dominates the personality and continuously transforms the mental state, twisting emotional truth. The delusional imagination is so deeply rooted in the patient's mental functioning that, even after systematic analysis, the delusional world, which had seemed to disappear, re‐emerges under new configurations. The psychotic core remains encapsulated; it produces unsteadiness and may induce further psychotic states in the patient. The author reports some analytic material of a patient, who, after a delusional episode treated with drugs, shows a vivid psychotic functioning. Some considerations are added on the nature of the psychotic state and on the therapeutic approach used to transform the delusional structure. This paper particularly deals with the difficulty in working through the psychotic episode and in ‘deconstructing’the delusional experience because of the terror connected with it. In the reported case, the analytic work changed the delusional construction into a more benign one characterised by phobic qualities. The analysis of the psychotic transference allowed the focus to be on the hidden work which had been continuously influencing the transferential picture of the analyst and the patient's psychic reality.
