HPA-Axis Activation as a Key Moderator of Childhood Trauma Exposure and Adolescent Mental Health

Individual differences in a child’s sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n?=?121, ages 9–16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child’s trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments.     

Emotions,Motivation, and Character: A Phenomenological Perspective

In this paper, I wish to explore whether and how emotions build on a state of being motivated that is linked to character and requires the positive contribution of habit. Drawing on phenomenological accounts of motivation (most notably Husserl’s and Merleau-Ponty’s), I argue that the relation between emotions and character depends on the institution of an emotional space, which is responsible for our sensitivity to the values of the felt situation and yet it is open to changes and revisions.     

Early Eye Movement Desensitisation and Reprocessing (EMDR) intervention in a disaster mental health care context

‘Early psychological intervention’ is defined as commencing treatment within three months of the traumatic event, with the aim to prevent or treat posttraumatic stress disorder, ongoing distress or acute stress disorder. In natural disaster situations, specific issues may limit the amount of time available for treatment and the possibility of interventions. Eye Movement Desensitisation and Reprocessing (EMDR) can be used without regard to these limits. The aim of the study is to evaluate the effects of EMDR, Recent Traumatic Episode Protocol (R-TEP) provided within three months of the traumatic event to a large sample of individuals exposed to the earthquake that hit Emilia Romagna Region (Northern Italy) in 2012. This study is based on a retrospective review of medical records collected during the activities of psychological and psychosocial unit in the immediate aftermath of earthquake. In total, 529 participants completed the Impact of Event Scale Revised (IES-R) (pre e post treatment). In order to provide a comparison similar to a waitlist-like control group, a method of cohort analysis was applied. In addition, possible time dependent effect was tested. ET (early-treated sample, participants treated within one month after the earthquake) and LT (late-treated sample, participants treated after the first month from the earthquake) reported at post-treatment an improvement to a level below the IES-R cutoff (65.8% of the ET sample and 64.02% of the LT sample). Control group analogue and time-outcome correlation suggest that positive changes in symptoms were likely due to the treatment provided and not merely to the time lapse from the traumatic event. The results of this study suggest that EMDR is a viable treatment option in response to a disaster crisis and in reducing psychological distress of acutely traumatized individuals within the context of a natural disaster.     

Children's selective trust decisions: rational competence and limiting performance factors

Recent research has amply documented that even preschoolers learn selectively from others, preferring, for example, reliable over unreliable and competent over incompetent models. It remains unclear, however, what the cognitive foundations of such selective learning are, in particular, whether it builds on rational inferences or on less sophisticated processes. The current study, therefore, was designed to test directly the possibility that children are in principle capable of selective learning based on rational inference, yet revert to simpler strategies such as global impression formation under certain circumstances. Preschoolers (N = 75) were shown pairs of models that either differed in their degree of competence within one domain (strong vs. weak or knowledgeable vs. ignorant) or were both highly competent, but in different domains (e.g., strong vs. knowledgeable model). In the test trials, children chose between the models for strength‐ or knowledge‐related tasks. The results suggest that, in fact, children are capable of rational inference‐based selective trust: when both models were highly competent, children preferred the model with the competence most predictive and relevant for a given task. However, when choosing between two models that differed in competence on one dimension, children reverted to halo‐style wide generalizations and preferred the competent models for both relevant and irrelevant tasks. These findings suggest that the rational strategies for selective learning, that children master in principle, can get masked by various performance factors.     

Ambiguous emotion recognition in temporal lobe epilepsy: The role of expression intensity

The lateralization of emotion processing is currently debated and may be further explored by examining facial expression recognition (FER) impairments in temporal lobe epilepsy (TLE). Furthermore, there is also debate in the literature whether FER deficits in individuals with TLE are more pronounced in the right than in the left hemisphere. Individuals with TLE were tested with an FER task designed to be more sensitive than those classically used to shed light on this issue. A total of 25 right- and 32 left-TLE patients, candidates for surgery, along with controls, underwent an FER task composed of stimuli shown not only at full-blown intensities (100 %), but also morphed to lower-intensity display levels (35 %, 50 %, and 75 %). The results showed that, as compared to controls, right-TLE patients showed deficits in the recognition of all emotional categories. Furthermore, when considering valence, right-TLE patients were impaired only in negative emotion recognition, but no deficits for positive emotions were highlighted in left-TLE patients. Finally, only the right-TLE patients’ impairment was found to be related to the age of epilepsy onset. Our work demonstrates that the FER deficits in TLE span multiple emotional categories and show manifestations dependent on the laterality of the epileptic focus. Taken together, our findings provide the strongest evidence for the right-hemisphere model, but they also partially support the valence model. We suggest that current models are not exhaustive at explaining emotional-processing cerebral control, and further that multistep models should be developed.     

Multilevel Correlates of Childhood Physical Aggression and Prosocial Behavior

The study identified independent individual, family, and neighborhood correlates of children's physical aggression and prosocial behavior. Participants were 2,745 2–11-year olds nested in 1,982 families, which were themselves nested in 96 Canadian neighborhoods. Hierarchical linear modeling showed that the total variation explained by the three-level model was 28.03% for physical aggression and 17.57% for prosocial behavior. For both childhood behaviors, approximately 66% of this explained variance was between individuals and up to 30% was between families. The smallest amount of observed variation was between neighborhoods. Significant individual-level predictors common to both childhood behaviors were child's sex and maternal hostility toward the target child. Specifically, boys had more mother-reported physical aggression and less prosocial behavior. Children who experienced greater-than-average maternal hostility (compared to siblings) were more physically aggressive and less prosocial. At the family level, significant common predictors were mother depressed mood and punitive parenting. Children had higher levels of physical aggression and lower levels of prosocial behavior in families where mothers had greater depressed mood and used more punitive parenting practices. At the neighborhood level, greater perceived problems and lower poverty level were associated with higher levels of physical aggression. Results are discussed with reference to past and future studies of multilevel effects on children's socialization.     

Question asking and eye tracking during cognitive disequilibrium: Comprehending illustrated texts on devices when the devices break down

The PREG model of question asking assumes that questions emerge when there is cognitive disequilibrium, as in the case of contradictions, obstacles, and anomalies. Participants read illustrated texts about everyday devices (e.g., a cylinder lock) and then were placed in cognitive disequilibrium through a breakdown scenario (e.g., the key turns but the bolt does not move). The participants asked questions when given the breakdown scenario, and an eyetracker recorded their fixations. As was predicted, deep comprehenders asked better questions and fixated on device components that explained the malfunction. The eye fixations were examined before, during, and after the participants' questions in order to trace the occurrence and timing of convergence on faults, causal reasoning, and other cognitive processes.
