This work adopts a perspective that construes acculturation as a dynamic intergroup process, and social contact with members of the new community as a key mechanism underlying cultural adaptation. We argue that migrants' initial self-reported mainstream cultural orientation constitutes an important antecedent of early social participation in the new community. Results from two longitudinal studies of newly arrived international students (N = 98 and N = 60) show that more positive initial mainstream cultural orientations prospectively predict higher social participation, specifically in the mainstream group, over the following months...

The present study examined sympathetic and parasympathetic indices of autonomic nervous system reactivity as moderators of the prospective association between parental management of peers via directing of youths' friendships and peer adjustment in a sample of typically developing adolescents. Participants included 246 adolescents at Time 1 (T1) [47% boys; 66% European American (EA), 34% African American (AA)] and 226 adolescents at Time 2 (T2; 45% boys; 67% EA, 33% AA). Adolescents were approximately 16 and 17 years old at T1 and T2, respectively...

Physical activity, alcohol use and smoking might affect cardiovascular disease through modifying autonomic nervous system (ANS) activity. We investigated: 1) whether there are consistent relationships between lifestyle factors and cardiac ANS activity over time, and 2) whether 2-year changes in lifestyle factors relate to 2-year changes in cardiac activity. Baseline (n=2618) and 2-year follow-up (n=2010) data of the Netherlands Study of Depression and Anxiety was combined. Baseline data was collected in the Netherlands from 2004-2007...

The goal of the current study was to investigate the association between relational victimization, defined as being the target of aggressive acts that damage relationships (e.g., gossip, social exclusion) and depressive symptoms during the relatively understudied developmental period of emerging adulthood. In addition, as individual differences in stress reactivity may influence the outcomes associated with victimization by peers, the moderating roles of sympathetic nervous system (SNS; as measured by skin conductance reactivity) and parasympathetic nervous system (PNS; as measured by respiratory sinus arrhythmia) reactivity to social and non-social stressors were examined...

: Dysfunction of biological stress systems and adverse life events, both independently and in interaction, have been hypothesized to predict chronic pain persistence. Conversely, these factors may hamper the improvement of chronic pain. Longitudinal evidence is currently lacking. We examined whether (1) function of biological stress systems, (2) adverse life events, and (3) their combination predict the improvement of chronic multi-site musculoskeletal pain. Subjects of the Netherlands Study of Depression and Anxiety (NESDA) with chronic multi-site musculoskeletal pain at baseline (n=665) were followed-up 2, 4 and 6 years later...

OBJECTIVE: Attenuated activity of stress-regulating systems has consistently been reported in boys with conduct problems. Results in studies of girls are inconsistent, which may result from the high prevalence of comorbid post-trauma symptoms. Therefore, the aim of the present study is to investigate post-trauma symptoms as a potential mediator in the relation between stress-regulation systems functioning and conduct problems in female adolescents. METHODS: The sample consisted of 78 female adolescents (mean age 15...

Positive urgency, defined as a tendency to become impulsive during positive affective states, has gained support as a form of impulsivity that is particularly important for understanding psychopathology. Despite this, little is known about the emotional mechanisms and correlates of this form of impulsivity. We hypothesized that positive urgency would be related to greater emotional reactivity in response to a positive film clip. Seventy-five undergraduates watched a positive film clip, and a multimodal assessment of emotion was conducted, including subjective emotional experience, physiological activation (i...

The somatic marker hypothesis posits that autonomic activity occurring in response to specific stimuli aids in implicit learning, the learning of information without explicit awareness of what has been learned. This study investigated whether respiratory sinus arrhythmia (RSA), a measure of autonomic nervous system activity, predicted changes in implicit learning. The interaction of resting RSA and RSA reactivity (change in RSA during the implicit learning task) was associated with changes in implicit learning, with those who had higher resting RSA and greater RSA withdrawal during the task performing better...

Maternal prenatal anxiety is associated with infants' temperamental negative affectivity (NA), but it is unclear to what extent children vary in their susceptibility to prenatal influences. We tested a hypothesis that infants' respiratory sinus arrhythmia (RSA), an index of parasympathetic vagal tone and a potential marker of differential susceptibility to environmental influences, moderates the effects of maternal prenatal anxiety on the development of infant NA. Prenatal anxiety was assessed during the last trimester of pregnancy in a low-risk community sample...

The present studies examined the influence of extraversion on physiological reactivity, recovery, and physiological habituation-sensitization to repeated social stressors. In Study 1, subjective and physiological data were collected from 97 college students who were categorized as high (n = 51) and low (n = 46) on extraversion (NEO-FFI) across five laboratory stages: baseline, stress 1, poststress 1, stress 2, and poststress 2. Results indicated high extraversion (HE) participants exhibited relative lesser heart rate (HR) reactivity and respiratory sinus arrhythmia (RSA) withdrawals to, and more complete HR and RSA recovery after the first social stress, and also exhibited relative lesser HR reactivity to the second social stress...

This study examined the direct and interactive effects of infants' respiratory sinus arrhythmia (RSA) and maternal depressive symptoms (MDS) during the first 6 months of life in the prediction of children's sleep problems at age 18 months. Participants included 156 children and their mothers who were followed from 3 to 18 months of age. At ages 3 and 6 months, infants' cardiac activity was recorded at rest and during the still-face paradigm, a mother-child social challenge task, and estimates of infant baseline RSA (RSAB) and RSA withdrawal (RSAW) were calculated...

This study employed piecewise growth curve modeling to examine how children's executive function (EF) skills relate to different components of children's physiological response trajectory - initial arousal, reactivity, and recovery. The sample included 102 ethnically diverse kindergarteners, whose EF skills were measured using standard tasks and observer ratings. Physiological response was measured via changes in respiratory sinus arrhythmia (RSA) in response to a laboratory socio-cognitive challenge. Children's cool and hot EF skills were differentially related to both linear and quadratic components of RSA response during the challenge...

The efficacy of adenotonsillectomy for relieving obstructive sleep apnoea symptoms in children has been firmly established, but its precise effects on cardiorespiratory control are poorly understood. In 375 children enrolled in the Childhood Adenotonsillectomy Trial, randomised to undergo either adenotonsillectomy (n=194) or a strategy of watching waiting (n=181), respiratory rate, respiratory sinus arrhythmia and heart rate were analysed during quiet, non-apnoeic and non-hypopnoeic breathing throughout sleep at baseline and at 7 months using overnight polysomnography...

The present review is concerned with the role of different physiological systems (e.g., skin conductance, heart rate, electromyography, and the eye-bling startle reflex) in understanding heterogeneity in conduct disorder (CD). Four subtyping approaches are considered: age of onset, comorbid psychopathology, callous-unemotional traits, and proactive/reactive aggression. Empirical findings are discussed in terms of distinct theoretical perspectives that aim to explain CD behaviors based on physiological over-arousal, under-arousal, and empathy deficits...

Facial mimicry and vagal regulation represent two crucial physiological responses to others' facial expressions of emotions. Facial mimicry, defined as the automatic, rapid and congruent electromyographic activation to others' facial expressions, is implicated in empathy, emotional reciprocity and emotions recognition. Vagal regulation, quantified by the computation of Respiratory Sinus Arrhythmia (RSA), exemplifies the autonomic adaptation to contingent social cues. Although it has been demonstrated that childhood maltreatment induces alterations in the processing of the facial expression of emotions, both at an explicit and implicit level, the effects of maltreatment on children's facial mimicry and vagal regulation in response to facial expressions of emotions remain unknown...

Cardiovascular variabilities were recognized over 250 years ago, but only in the past 20 years has their apparent utility come to be appreciated. Technological advancement has allowed precise measurement and quantification of short-term cardiovascular fluctuations; however, our understanding of the integrated mechanisms which underlie these oscillations is inadequate for their widespread application. Both autonomic branches, the parasympathetic and sympathetic nervous system, are key determinants of the magnitude of these spontaneous cardiovascular fluctuations...

BACKGROUND: Low childhood socioeconomic status (SES) is reliably associated with poor adult health. Social environments early in life and physiological stress responses are theorized to underlie this link; however, the role of attachment orientations is relatively unknown. PURPOSE: In this study, we examined whether attachment orientations (i.e., attachment anxiety and attachment avoidance) and self-reported stress were mediators of the association between childhood SES and self-reported health in adulthood...

OBJECTIVE: Mothers who attribute child misbehaviors to children's intentions, and not to situational causes, show more hostile parenting behaviors. Why are some mothers more likely than others to make more hostile attributions (i.e., high intentional attributions and low situational attributions) when confronted with child challenging behaviors? We examined the relation between mothers' perception of child challenging behaviors and their hostile attributions of child misbehaviors, with an emphasis on how maternal negative affect and resting vagal activity moderated this relation...
