Electrical Brain Activity,Family Functioning,and Parent–Adolescent Conflict Communication

As family conflict tends to escalate during the adolescent years, the subsequent effects of adolescence on parent–child dynamics are systemically experienced, both intra- and inter-personally. As such, widening the scope of literature targeted towards better understanding the parent–adolescent conflict relationship is merited. To offer a more gestalt view of parent–adolescent conflict processes, the present study takes a biopsychosocial view of the mother–father–adolescent relationship by considering electrical brain activity using electroencephalography technology. Specifically, electrical brain activity was recorded during two problem-solving family discussions between a mother, father, and adolescent child. Data is analyzed from a pilot study of 11 triads, for a total of 33 participants, examining the statistical relationships between brain waves and self-reported measures of family functioning and distress. Findings suggest that hemispheric lateralization occurs during parent–adolescent problem-solving discussions thus reminding therapists of the importance in using a biopsychosocial lens when assisting families.     

Repetition blindness reveals differences between the representations of manipulable and nonmanipulable objects

We used repetition blindness to investigate the nature of the representations underlying identification of manipulable objects. Observers named objects presented in rapid serial visual presentation streams containing either manipulable or nonmanipulable objects. In half the streams, 1 object was repeated. Overall accuracy was lower when streams contained 2 different manipulable objects than when they contained only nonmanipulable objects or a single manipulable object. In addition, nonmanipulable objects induced repetition blindness, whereas manipulable objects were associated with a repetition advantage. These findings suggest that motor information plays a direct role in object identification. Manipulable objects are vulnerable to interference from other objects associated with conflicting motor programs, but they show better individuation of repeated objects associated with the same action.

Effects of school‐based mindfulness training on emotion processing and well‐being in adolescents: evidence from event‐related potentials

In a non‐randomized controlled study, we investigated the efficacy of a school‐based mindfulness curriculum delivered by schoolteachers to older secondary school students (16–18 years). We measured changes in emotion processing indexed by P3b event‐related potential (ERP) modulations in an affective oddball task using static human faces. ERPs were recorded to happy and sad face oddballs presented in a stimulus stream of frequent faces with neutral expression, before and after 8 weeks of mindfulness training. Whilst the mean amplitude of the P3b, an ERP component typically elicited by infrequent oddballs, decreased between testing sessions in the control group, it remained unchanged in the training group. Significant increases in self‐reported well‐being and fewer doctor visits for mental health support were also reported in the training group as compared to controls. The observed habituation to emotional stimuli in controls thus contrasted with maintained sensitivity in mindfulness‐trained students. These results suggest that in‐school mindfulness training for adolescents has scope for increasing awareness of socially relevant emotional stimuli, irrespective of valence, and thus may decrease vulnerability to depression.     

Hallucinations in schizophrenia, sensory impairment, and brain disease: a unifying model

Based on recent insight into the thalamocortical system and its role in perception and conscious experience, a unified pathophysiological framework for hallucinations in neurological and psychiatric conditions is proposed, which integrates previously unrelated neurobiological and psychological findings. Gamma-frequency rhythms of discharge activity from thalamic and cortical neurons are facilitated by cholinergic arousal and resonate in networks of thalamocortical circuits, thereby transiently forming assemblies of coherent gamma oscillations under constraints of afferent sensory input and prefrontal attentional mechanisms. If perception is based on synchronisation of intrinsic gamma activity in the thalamocortical system, then sensory input to specific thalamic nuclei may merely play a constraining role. Hallucinations can be regarded as underconstrained perceptions that arise when the impact of sensory input on activation of thalamocortical circuits and synchronisation of thalamocortical gamma activity is reduced. In conditions that are accompanied by hallucinations, factors such as cortical hyperexcitability, cortical attentional mechanisms, hyperarousal, increased noise in specific thalamic nuclei, and random sensory input to specific thalamic nuclei may, to a varying degree, contribute to underconstrained activation of thalamocortical circuits. The reticular thalamic nucleus plays an important role in suppressing random activity of relay cells in specific thalamic nuclei, and its dysfunction may be implicated in the biological vulnerability to hallucinations in schizophrenia. Combined with general activation during cholinergic arousal, this leads to excessive disinhibition in specific thalamic nuclei, which may allow cortical attentional mechanisms to recruit thalamic relay cells into resonant assemblies of gamma oscillations, regardless of their actual sensory input, thereby producing an underconstrained perceptual experience.     

Ensemble coding of faces occurs in children and develops dissociably from coding of individual faces

Ensemble coding allows adults to access useful information about average properties of groups, sometimes even in the absence of detailed representations of individual group members. This form of coding may emerge early in development with initial reports of ensemble coding for simple properties (size, numerosity) in young children and even infants. Here we demonstrate that ensemble coding of faces, which provides information about average properties of social groups, is already present in 6–8‐year‐old children. This access to average information increases with age from 6 to 18 years and its development is dissociable from age‐related improvements in the coding of individual face identities. This dissociation provides the first direct evidence that distinct processes underlie ensemble and individual coding of face identity, evidence that has been lacking from adult studies. More generally, our results add to the emerging evidence for impressively mature sensitivity to statistical properties of the visual environment in children. They indicate that children have access to gist information about social groups that may facilitate adaptive social behaviour.     

Support groups for parents with an adult child suffering from bipolar disorder

Confronted with the disconcerting behaviour exhibited by their children, parents of bipolar patients are in severe distress. Research focuses on the study of the ‘burden’ that the pathology puts on caregivers, owing to their experience of depression, sometimes combined with the presence of hostile attitudes and negative affects. In France, parents of adult patients encounter an initial specific difficulty: they are not systematically included in the care management system. Thanks to the initiative of an association of psychiatrists and psychoanalysts, the authors set up a psychoanalytic support group for the parents of ‘bipolar’ adults. The diagnosis of a bipolar disorder is established by a psychiatrist within a medical structure. Support groups for parents do exist in France, but their experiences have not led to scientific publications on this specific topic. Existing publications focus on other types of pathology and other therapeutic approaches. In this article, we will highlight how this type of psychoanalytic support group, with operating rules based on the theoretical work of Anzieu, can help parents of patients with bipolar disorders. Group participants accepted the principle of a research study that maintained their anonymity. We collected and analysed qualitative data from the first year of the group, so we highlight the specific difficulties of these parents, faced with chronic disease. The relevance of our qualitative study also resides in the data collected over a period of time, enabling us to see the progress made, and encouraging us to reflect on the place of psychoanalytic groups for parents, as well as on the care management of this pathology.     

Executive Functions in Children and Adolescents with Turner Syndrome: A Systematic Review and Meta-Analysis

Turner syndrome (TS) is a genetic disorder, affecting 1/2500 to 1/3000 live female births, induced by partial or total deletion of one X chromosome. The neurocognitive profile of girls with TS is characterized by a normal Verbal IQ and weaknesses in visual-spatial, mathematics, and social cognitive domains. Executive functions (EFs) impairments have also been reported in these young patients. However, methodological differences across studies do not allow determination of which EFs are impaired and what is the magnitude of these impairments. The aim of this review was to clarify the EF profile of children and adolescents with TS. Sixteen samples, from thirteen studies, were included in the current meta-analysis. EFs measures used in these studies were classified into working memory, inhibitory control, cognitive flexibility, or higher-order EFs tasks in accordance with Diamond’s model, Annual Review of Psychology, 64, 135–168 (2013). Results confirmed that girls with TS had significant executive impairments with effect sizes varying from small (inhibitory control) to medium (cognitive flexibility) and large (working memory, higher-order EFs). Analyses by task revealed that cognitive inhibition may be more impaired than the other inhibitory control abilities. Heterogeneity across cognitive flexibility measures was also highlighted. Between-sample heterogeneity was observed for three tasks and the impact of participants’ characteristics on EFs was discussed. This meta-analysis confirms the necessity to assess, in patients living with TS, each EF by combining both visual and verbal tasks. Results also underline that, when studying girls with TS’ executive profile, it is important to explore the impact of moderator variables, such as IQ, parental socio-economic status, TS karyotype, psychiatric comorbidities, and hormonal treatment status.     

Brief Counseling for Alcohol Misuse Among Trauma Patients: Two Interventions and Influence of Baseline Use

This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors.     

Hands-On,Shoes-Off: Multisensory Tools Enhance Family Engagement Within an Art Museum

Families with young children typically struggle to engage with traditional art museum environments. This research examined the impact of multisensory tools on family engagement within Mathaf: Arab Museum of Modern Art, Qatar. Sixty families with at least one child aged 0–11 were observed during two tasks. One task required participants to look at a series of paintings to select their favorite. In another task, families were given a toolkit of multisensory items to facilitate interaction with a painting. A semi-structured observational method produced quantitative and qualitative data about participant engagement and intergenerational interaction. Self-rating scores of task enjoyment were also collected. Results indicate that multisensory tools enhance family engagement with museums, artworks, and each other. Results also suggest that word-based interpretation was not necessary. We consider the potential implications of these findings in relation to family programming within art museums and museums more generally.
