Dimensions of childhood adversity differentially affect autonomic nervous system coordination in response to stress.

It is well-established that disrupted autonomic nervous system (ANS) reactivity exacerbates risk for long-term maladjustment following childhood adversity (CA). However, few studies have integrated measures of both the sympathetic (SNS) and parasympathetic (PNS) branches of the ANS, resulting in a unidimensional understanding of ANS functioning as a mechanism of risk. Further, past work has primarily measured CA only at the aggregate level (e.

Parental Depression Symptoms, Skin Conductance Level Reactivity and Parenting: Associations with Youth Psychopathology.

Parental depression symptoms are a prevalent risk factor for internalizing and externalizing problems in youth, with parenting and parents' physiological stress reactivity representing potential contributing factors in the intergenerational transmission of psychopathology symptoms. In a sample of adolescents (N = 97) and their parents, the current study examined parental depression symptoms, an observational measure of parenting, and parents' physiological reactivity during a dyadic conflict discussion task in association with adolescents' internalizing and externalizing psychopathology. Parental depression symptoms and harsh/insensitive parenting showed positive associations with youth psychopathology symptoms.

Momentary autonomic engagement during parent-adolescent conflict: Coping as a moderator of associations with emotions.

Regulatory efforts are hypothesized to affect associations between emotions and physiology (i.e., concordance) to facilitate adaptive functioning.

Threat exposure moderates associations between neural and physiological indices of emotion reactivity in adolescent females.

Early life adversity (ELA) characterized by threat (e.g., abuse, witnessing violence) impacts neural and physiologic systems involved in emotion reactivity; however, research on how threat exposure impacts the interplay between these systems is limited.

Physiology and emotions: Within individual associations during caregiver-adolescent conflict.

Concordance between physiological and emotional responses is central to models of emotion and has been shown to correspond to effective responses and well-being in adults. A deeper understanding of physiological-emotional concordance during ecologically relevant scenarios is essential to then determine if these associations predict mental health problems or can serve as a helpful biomarker of risk or resilience in adults and youth. The present study assessed the minute-to-minute associations between sympathetic (i.

Racial/ethnic differences in parenting behaviors among depressed parents.

Low parental warmth and high control are associated with parental depression and with the development of depression in children. The majority of this research, however, has focused on non-Hispanic White (NHW) parents. The present study tested whether parenting behaviors differed by race/ethnicity in a sample ( = 169) of parents with a history of depression.

Adolescents' Coping and Internalizing Symptoms: Role of Maternal Socialization of Coping and Depression Symptoms.

Parental emotion socialization, including processes of the socialization of coping and emotion regulation, is a key factor in shaping children's adjustment in response to acute and chronic stress. Given well-established links between parental depression and youth psychopathology, levels of parental depression symptoms are an important factor for understanding emotion socialization and regulation processes. The present study examined associations among maternal coping and depression symptoms with their adolescents' coping and internalizing problems.

Child Anxiety and Depression Symptom Trajectories and Predictors over 15 Months of the Coronavirus Pandemic.

Repeated measures are required to monitor and map trajectories of mental health symptoms that are sensitive to the changing distal and proximal stressors throughout the coronavirus (COVID-19) pandemic. Understanding symptoms in young children is particularly important given the short- and long-term implications of early-onset internalizing symptoms. This study utilized an intensive longitudinal approach to assess the course and environmental correlates of anxiety and depression symptoms in 133 children, ages 4-11 (M = 7.

Terminal H-reflex Measurements in Mice.

The Hoffmann reflex (H-reflex), as an electrical analog to the stretch reflex, allows electrophysiological validation of the integrity of neural circuits after injuries such as spinal cord damage or stroke. An increase of the H-reflex response, together with symptoms like non-voluntary muscle contractions, pathologically augmented stretch reflex, and hypertonia in the corresponding muscle, is an indicator of post-stroke spasticity (PSS). In contrast to rather nerve-unspecific transcutaneous measurements, here, we present a protocol to quantify the H-reflex directly at the ulnar and median nerves of the forepaw, which is applicable, with minor modifications, to the tibial and sciatic nerve of the hindpaw.

Thorax-Segment- and Leg-Segment-Specific Motor Control for Adaptive Behavior.

We have just started to understand the mechanisms underlying flexibility of motor programs among segmental neural networks that control each individual leg during walking in vertebrates and invertebrates. Here, we investigated the mechanisms underlying curve walking in the stick insect during optomotor-induced turning. We wanted to know, whether the previously reported body-side specific changes in a two-front leg turning animal are also observed in the other thoracic leg segments.

Mean-level correspondence and moment-to-moment synchrony in adolescent and parent affect: Exploring associations with adolescent age and internalizing and externalizing symptoms.

Interactions with parents are integral in shaping the development of children's emotional processes. Important aspects of these interactions are overall (mean level) affective experience and affective synchrony (linkages between parent and child affect across time). Respectively, mean-level affect and affective synchrony reflect aspects of the content and structure of dyadic interactions.

Adverse childhood experiences, parenting, and socioeconomic status: Associations with internalizing and externalizing symptoms in adolescence.

Background: Adverse childhood experiences (ACEs), low socioeconomic status (SES), and harsh parenting practices each represent well-established risk factors for mental health problems. However, research supporting these links has often focused on only one of these predictors and psychopathology, and interactions among these variables in association with symptoms are not well understood.

Objective: The current study utilized a cross-sectional, multi-informant, and multi-method design to investigate the associations of ACEs, SES, parenting, and concurrent internalizing and externalizing problems in adolescents.

Predictors of family violence in North Carolina following initial COVID-19 stay-at-home orders.

Background: Although there is evidence that family violence increased in the United States during the COVID-19 pandemic, few studies have characterized longitudinal trends in family violence across the course of initial stay-at-home orders.

Objective: The purpose of the present study is to investigate patterns and predictors of family violence, such as child maltreatment and harsh punishment, during the first eight weeks of the pandemic after initial stay-at-home orders in North Carolina.

Participants And Setting: Participants included 120 families with children ages 4-11 (53% non-White, 49% female) and a primary caregiver (98% female) living in rural and suburban areas in North Carolina.

Child Hostility toward a Parent with a History of Depression and Family Functioning.

Family dysfunction has been associated with both child externalizing problems, including hostility, and parent depression or depressive symptoms. Research investigating child hostility directed toward a parent with a history of depression is absent, yet it may be associated with especially high levels of family dysfunction. The current study aimed to assess (1) the relation between observed child hostility, measured by the Iowa Family Interaction Rating Scale, toward such a parent and child-reported family dysfunction, using the Family Assessment Device, and (2) whether current parent depressive symptoms, measured by the Beck Depression Inventory-II, moderated this association.

Optical inactivation of a proprioceptor in an insect by non-genetic tools.

Background: The specific role of sensory organs in locomotor pattern generation is traditionally investigated by means of mechanical ablation in arthropods that currently do not allow genetic manipulation. Mechanical ablation is irreversible, and may lead to injury discharges and changes in the structural integrity of the cuticle.

New Method: Here, we present a new method to temporarily or permanently deprive parts of an insect nervous system of sensory feedback from leg proprioceptors by means of blue light application.

Observed Maternal Coping Socialization and Child Internalizing Symptoms: The Roles of Maternal Depressive Symptoms and Peer Stress.

Empirical evidence relying primarily on questionnaire reports indicates parent coping socialization messages play an important role in children's psychological functioning. The present study utilized a multi-informant, multi-method design to build on previous coping socialization research in childhood and adolescence. A novel coding system was developed to measure observed parental socialization of coping messages from observations of a discussion-based peer stress task.

Working memory training in pediatric brain tumor survivors after recent diagnosis: Challenges and initial effects.

Research shows promise for cognitive interventions for children diagnosed with brain tumors. Interventions have been delivered approximately 5 years postdiagnosis on average, yet recent evidence shows cognitive deficits may appear near diagnosis. The present study assessed the feasibility and initial effects of working memory training in children with brain tumors delivered soon after diagnosis and followed 2 years postdiagnosis.

Comparison of three models of adverse childhood experiences: Associations with child and adolescent internalizing and externalizing symptoms.

Exposure to adverse childhood experiences (ACEs) is prevalent and confers risk for psychopathology later in life. Approaches to understanding the impact of ACEs on development include the independent risk approach, the Dimensional Model of Adversity and Psychopathology (DMAP) distinguishing between threat and deprivation events, and the cumulative risk approach. The present research provides an empirical confirmation of DMAP and a comparison of these three approaches in predicting internalizing and externalizing symptoms in youth.

Introduction to spasticity and related mouse models.

Although spasticity is one of the most common causes of motor disability worldwide, its precise definition and pathophysiology remain elusive, which to date renders its experimental targeting tricky. At least in part, this difficulty is caused by heterogeneous phenotypes of spasticity-causing neurological disorders, all causing spasticity by involving upper motor neurons. The most common clinical symptoms are a series of rapid muscle contractions (clonus), an increased muscle tone (hypertonia), and augmented tendon reflex activity (hyperreflexia).

Effects of maltreatment on coping and emotion regulation in childhood and adolescence: A meta-analytic review.

Background: Child maltreatment is consistently linked to adverse mental and physical health problems, making the identification of risk and resilience processes crucial for prevention efforts. The ways that individuals cope and regulate emotions in response to stress may buffer against pre-existing risk, while deficits in these processes have the potential to amplify risk. Thus, a candidate mechanism to explain the association between early-life abuse and neglect and later maladjustment is the way in which previously-maltreated youth respond to stress throughout development.

Predictors of placement disruptions in foster care.

Background: Many children who are removed from a dangerous or neglectful home and placed in state custody subsequently experience additional disruptions while in custody, which can compound the effects of ongoing stress and instability. As such, placement stability has been identified as a critical objective and a key indicator of success for children residing in substitutive care.

Objective: To examine the utility of child protective services data in identifying predictors of placement disruption.

Stress Exposure and Maternal Depression as Risk Factors for Symptoms of Anxiety and Depression in Adolescents.

Little research has explored the implications of stress inside and outside of the family as a risk factor for psychological symptoms in adolescents of depressed mothers. In a sample of 115 adolescents and their mothers with and without depression histories, adolescents' family and peer stress exposure was measured through the Responses to Stress Questionnaire, and adolescents' anxious/depressed symptoms were measured with the Youth Self Report and Child Behavior Checklist. Mothers reported their current depression symptoms on the Beck Depression Inventory-II.

Body side-specific changes in sensorimotor processing of movement feedback in a walking insect.

Feedback from load and movement sensors can modify timing and magnitude of the motor output in the stepping stick insect. One source of feedback is stretch reception by the femoral chordotonal organ (fCO), which encodes such parameters as the femorotibial (FTi) joint angle, the angular velocity, and its acceleration. Stimulation of the fCO causes a postural resistance reflex, during quiescence, and can elicit the opposite, so-called active reaction (AR), which assists ongoing flexion during active movements.
