RESUMEN

Both cortical and parasympathetic systems are believed to regulate emotional arousal in the service of healthy development. Systemic coordination, or coupling, between putative regulatory functions begins in early childhood. Yet the degree of coupling between cortical and parasympathetic systems in young children remains unclear, particularly in relation to the development of typical or atypical emotion function. We tested whether cortical (ERN) and parasympathetic (respiratory sinus arrhythmia [RSA]) markers of regulation were coupled during cognitive challenge in preschoolers (N = 121). We found no main effect of RSA predicting ERN. We then tested children's typical and atypical emotion behavior (context-appropriate/context-inappropriate fear, anxiety symptoms, neuroendocrine reactivity) as moderators of early coupling in an effort to link patterns of coupling to adaptive emotional development. Negative coupling (i.e., smaller ERN, more RSA suppression or larger ERN, less RSA suppression) at age 3 was associated with greater atypical and less typical emotion behaviors, indicative of greater risk. Negative age 3 coupling was also visible for children who had greater Generalized Anxiety Disorder symptoms and blunted cortisol reactivity at age 5. Results suggest that negative coupling may reflect a maladaptive pattern across regulatory systems that is identifiable during the preschool years.

RESUMEN

Emotion regulation (ER) is critical for children's healthy socio-emotional development, in part through its modulation of negative emotions that might otherwise place children at risk for psychopathology. The cognitive ER strategy of reappraisal appears to be particularly protective against the development of symptoms of anxiety and depression during childhood. Despite widespread acceptance of the benefits of reappraisal for children's long-term affective function, little is known about the developmental mechanisms that support emerging reappraisal in young children. Proximal mechanisms supporting reappraisal include biological processes; the modulation of reactivity to negative emotional stimuli is visible at the neural level through the Late Positive Potential (LPP). Influences on the developmental course of mechanisms like the LPP almost certainly include contextual factors, including quality of the environment, which have been largely ignored in work to date. The present study included a test of early (age 3-4) socioeconomic status (SES) as a moderator of children's reappraisal, evidenced by differences in the LPP to passive view and reappraisal conditions, at age 5. Results supported the presence of moderation. Reappraisal was visible as differences in LPP across conditions at high, but not low, levels of SES. Findings offer a foundation for delineating the development of reappraisal and understanding contexts that may promote preschoolers' reappraisal. Results also contribute to the delineation of the role of early psychophysiological markers in affective function and early risk for psychopathology.

RESUMEN

Nancy Suchman's work highlighted the fundamental role of maternal mentalization in maternal addiction, mental health, and caregiving challenges. In this study, we aimed to examine the role of mental-state language (MSL) as a measure of mentalization in prenatal and postnatal narratives and their sentiment in a sample of 91 primarily White mothers from the western United States, followed from the second trimester of pregnancy, through the third trimester, to 4 months postpartum. Specifically, we investigated the use of affective and cognitive MSL in prenatal narratives when mothers visualized caring for their baby and postnatal narratives when mothers compared their prenatal visualization to the current caregiving reality. Results indicated moderate consistency in MSL between the second and third trimesters, but prenatal and postnatal MSL was not significantly correlated. Across all time points, higher use of MSL was related to more positive sentiment, indicating an association between mentalization and positive caregiving representations across the perinatal period. Women used more affective than cognitive MSL in prenatal imagination of caregiving, but this pattern was reversed in their postpartum reflection. Implications on assessing parental mentalization prenatally and considering the relative dominance of affective and cognitive mentalizing are discussed while considering study limitations.


El trabajo de Nancy Suchman subrayó el papel fundamental de la mentalización maternal en la adicción materna, la salud mental y los retos de la prestación de cuidado. En este estudio, nos propusimos examinar el papel del lenguaje del estado mental como una medida de mentalización en las narrativas pre- y postnatales y su sentimiento en un grupo muestra de 91 madres primariamente blancas del oeste de los Estados Unidos, a quienes se les dio seguimiento a partir del segundo trimestre de embarazo, a través del tercer trimestre, hasta 4 meses después del parto. Específicamente, investigamos el uso de lenguaje del estado mental afectivo y cognitivo en las narrativas prenatales cuando las madres visualizaban el cuidado de su bebé, y las narrativas postnatales cuando las madres comparaban su visualización prenatal con la presente realidad de prestación de cuidado. Los resultados indicaron una consistencia moderada en el lenguaje del estado mental entre el segundo y tercer trimestres, pero el lenguaje del estado mental prenatal y postnatal no fue significativamente correlacionado. A los largo de todos los punto temporales, el más alto uso del lenguaje del estado mental se relacionó con un más positivo sentimiento, indicando así una asociación entre la mentalización y las representaciones positivas de la prestación de cuidado a lo largo del período perinatal. Las mujeres usaron más lenguaje del estado mental afectivo que cognitivo en la imaginación prenatal de la prestación de cuidado, pero este patrón se invirtió en sus reflexiones después del parto. Se discuten las implicaciones sobre el tener acceso a la mentalización del progenitor prenatalmente y considerar el relativo dominio del mentalizarse en lo afectivo y cognitivo, al tiempo que se consideran las limitaciones del estudio.


Le travail de Nancy Suchman a mis en lumière le rôle fondamental de la mentalisation maternelle dans l'addiction maternelle, la santé mentale et les défis de la prestation de soins. Dans cette étude nous nous sommes donné pour but d'examiner le rôle du langage d'état mental en tant que mesure de la mentalisation dans les narrations prénatales et postnatales et leur sentiment chez un échantillon de 91 mères dans l'ensemble blanches vivant dans l'ouest des Etats-Unis d'Amériques, et suivies du second trimestre de la grossesse, durant le troisième trimestre jusqu'à 4 mois après la naissance. Plus particulièrement nous nous sommes penchés sur l'utilisation du langage d'état mental affectif et cognitif dans des narrations prénatales lorsque les mères visualisaient les soins à leur bébé, et les narrations postnatales lorsque les mères comparaient leur visualisation prénatale à la réalité actuelle des soins au bébé. Les résultats ont indiqué une cohérence modérée dans le langage d'état mental entre les second et troisième trimestres mais le langage d'état mental prénatal et postnatal n'était pas significativement corrélé. Au travers de tous les points temporels l'utilisation plus grande de langage d'état mental était liée à un sentiment plus positif, indiquant un lien entre la mentalisation et les représentations positives des soins au travers de la période périnatale. Les femmes ont utilisé un langage d'état mentale plus affectif que cognitif dans l'imagination prénatale des soins, mais ce schéma était renversé dans leur réflexion postpartum. Les implications pour l'évaluation de la mentalisation parentale avant la naissance et pour la considération de la domination relative de la mentalisation affective et cognitive sont discutées, tout en considérant les limites de l'étude.

RESUMEN

Background: Although the effects of maternal behavior on the development of child emotion characteristics is relatively well-established, effects of infant characteristics on maternal emotion development is less well known. This gap in knowledge persists despite repeated calls for including child-to-mother effects in studies of emotion. We tested the theory-based postulate that infant temperamental negativity moderates longitudinal trajectories of mothers' perinatal symptoms of anxiety and depression. Method: Participants were 92 pregnant community women who enrolled in a longitudinal study of maternal mental health; symptoms of anxiety and depression were assessed during the second and third trimesters of pregnancy and again at infant age 4 months. A multimethod assessment of infants' temperament-based negative reactivity was conducted at infant age 4 months. Results: Maternal symptoms of anxiety showed smaller postnatal declines when levels of infant negativity were high. Negative reactivity, assessed via maternal report of infant behavior, was related to smaller postnatal declines in maternal anxiety, while infant negative reactivity, at the level of neuroendocrine function, was largely unrelated to longitudinal changes in maternal anxiety symptoms. Infant negativity was related to early levels, but largely unrelated to trajectories of maternal symptoms of depression. Limitations: Limitations of this work include a relatively small and low-risk sample size, the inability to isolate environmental effects, and a nonexperimental design that precludes causal inference. Conclusions: Findings suggest that levels of infant negativity are associated with differences in the degree of change in maternal anxiety symptoms across the perinatal period.

RESUMEN

Despite widespread acceptance that prenatal symptoms of depression in mothers are detrimental to infants' long-term emotional and cognitive development, little is known about the mechanisms that may integrate outcomes across these domains. Rooted in the integrative perspective that emotional development is grounded in developing cognitive processes, we hypothesized that prenatal symptoms of depression in mothers would be associated with delays in neural maturation that support sociocognitive function in infants, leading to more problematic behaviors. We used a prospective longitudinal study of mothers (N = 92) and their infants to test whether self-reported symptoms of depression in mothers during the second and third trimesters were associated with neural development and infant outcomes at 4 months of age. While controlling for postpartum symptoms of depression, more prenatal symptoms of depression in mothers predicted less neural maturation in the parietal region of 4-month-old infants. Less neural maturation, in turn, was associated with greater infant negativity, suggesting neural maturation as a putative mechanism linking maternal symptoms of depression with infant outcomes. Differences in neural regions and developmental timing are also discussed.

RESUMEN

Children's peer victimization trajectories and their longitudinal associations with externalizing and internalizing problems were investigated from Grades 2 to 5. Secondary data analysis was performed with the Early Childhood Longitudinal Study (ECLS-K-2011; n = 13,860, M age = 8.1 years old in the spring of Grade 2; 51.1% male, 46.7% White, 13.2% African-American, 25.3% Hispanic or Latino, 8.5% Asian, and 6.1% other or biracial). Children who experienced high and persistent levels of peer victimization (high-chronic victims) exhibited co-occurring externalizing and internalizing problems. Moreover, among high-chronic victims, boys had a more pronounced increase in their externalizing trajectories, and girls had greater increases in their social anxiety trajectories. In contrast, those with decreasing peer victimization across time exhibited signs of recovery, particularly with respect to their social anxiety. These findings elucidated how chronic, increasing, and decreasing victims exhibited distinct patterns in the co-occurring development of their externalizing and internalizing problems, and how findings varied depending on the form of problem behavior and by child sex.

RESUMEN

Children from lower socioeconomic status (SES) families are at increased risk for anxiety problems, though knowledge of the pathways by which SES predicts children's anxiety outcomes remains scant. Limited work suggests SES as a moderator of links between early development and anxiety outcomes but has not used a longitudinal framework or a multimethod approach. In this preregistered study, SES was tested as a simultaneous moderator of putatively biologically (error-related negativity [ERN]) and contextually (authoritarian parenting) based pathways of anxiety risk from ages 3 (Mage = 3.59), 4 (Mage = 4.57), and 5 (Mage = 5.52) [N = 121; 59% female]. Families were largely White and Non-Hispanic and reported a broad range of income (less than $15,000 to $90,001 or greater) from 2014 to 2017. We hypothesized that putatively biological pathways would be the strongest predictors of child outcomes at high SES and that putatively contextual pathways would be the strongest predictors of child outcomes at low SES. Consistent with expectations, smaller ERN across ages 3 and 4 was associated with greater anxious behaviors at age 5, but only at high SES. SES did not moderate parenting-based pathways of risk. Results are partially consistent with previous work suggesting that putatively biological pathways are more robust predictors of child outcomes at high SES than at low SES.

RESUMEN

BACKGROUND: Stress during pregnancy can increase physical and mental health risks in parents and offspring. Emotion regulation (ER) may protect against prenatal stress; however, ER is understudied in expectant parents, particularly expectant fathers. This study aimed to evaluate associations between ER strategies (reappraisal, suppression, ratio of suppression-to-reappraisal) and perceived stress among expectant parents, and also test whether expectant mothers and fathers differed in ER strategy use and perceived stress levels. METHODS: N = 83 expectant parents (62.7% mothers) in the third trimester completed measures assessing perceived stress,reappraisal, and suppression. ANCOVA, hierarchical regression, and multilevel models were used to evaluate associations between ER strategies and perceived stress, and test for sex differences. RESULTS: Controlling for age and education, lower reappraisal and higher suppression were associated with higher perceived stress; in addition, higher suppression-to-reappraisal ratios were associated with greater perceived stress. Mothers and fathers did not differ in perceived stress, reappraisal, or suppression; however, suppression-to-reappraisal ratios significantly differed. CONCLUSION: Increasing ER skills such as reappraisal while reducing suppression may be beneficial for decreasing stress in expectant parents. Expectant fathers report similar levels of perceived stress to mothers and would benefit from prenatal mental health screening and intervention.

RESUMEN

A negative breastfeeding experience is a contextual risk factor for the development of postpartum depressive symptoms among mothers. Many current interventions targeted at disrupting this association rely on the ability to make breastfeeding experiences positive. As a beginning step toward identifying alternative approaches, we investigated a potential psychological buffer of the negative relation between breastfeeding experience and symptoms of postpartum depression: feeling authentic in one's role as a parent. Authenticity appears to enhance well-being and buffer negative outcomes more generally, but has largely gone unaddressed in mothers, particularly during the critical peripartum period when depressive symptoms are at increased prevalence. We tested whether three facets of felt authenticity in the parent role (authentic living, acceptance of external influence, and self-alienation) moderated the association between satisfaction with breastfeeding experience and postpartum depressive symptoms in mothers (N = 92, 81% White, 85% Non-Hispanic, college-educated, M age = 30.49). We found that mothers who felt high in authentic living in the parent role showed fewer depressive symptoms when breastfeeding experiences were positive. In addition, we found that the association between negative breastfeeding experience and greater postpartum depression was mitigated when feelings of self-alienation in the parent role, or the sense that one is unaware of or disconnected from who "she really is" as a mother, were low. This work suggests that enhancing women's feelings of connectedness to "who they truly are" as a mother may be protective against some of the negative mental health effects linked to problems with breastfeeding.

RESUMEN

Delta-beta coupling is increasingly used to understand early emotional development. However, little is known about the development of the coupling, limiting its utility for identifying normative or aberrant functioning. We used a prospective longitudinal sample (N = 122) to compare measures of within-person and between-person coupling between ages 3 and 5, track the developmental trajectory of coupling, identify individual differences in patterns of development, and explore emotion-related predictors and outcomes of discrete developmental patterns. Within-person measures, limited in overall utility, were most useful when (1) statistical approaches produced more homogenous groups within the overall sample (extreme groups or latent classes) or (2) the full developmental course was considered. We found two trajectories of change in frontal coupling and three trajectories of change in parietal coupling. Coupling trajectories were predicted by observed fear and approach/avoidance at age 3. In addition, high levels of frontal coupling at age 3 that declined and then levelled out through age 5 were associated with lower levels of internalizing by age 5. This work provides a foundation for understanding normative change in delta-beta coupling across the preschool years and useful insight for the use of this metric in future work.

RESUMEN

INTRODUCTION: Postpartum depression imparts a significant and long-lasting burden on maternal and child health. Successful prevention or early detection of postpartum depression will rely on the identification of early risk factors. Pain during pregnancy (before childbirth) is a key potential predictor of postpartum depression risk. However, longitudinal studies characterizing pregnancy pain, its normal trajectory over time, and its prospective relations with symptoms of postpartum depression are lacking. METHODS: We used data from a longitudinal study of maternal emotion that included assessments of pain and depressive symptoms at 3 time points-during the second and third trimester of pregnancy and at 4 months postpartum. Structural equation modelling was used to estimate longitudinal patterns of change in maternal pain over time. Latent growth curve parameters were tested as predictors of symptoms of postpartum depression. RESULTS: Ninety-three healthy pregnant women enrolled in this study. Although the sample comprised women with relatively low-risk pregnancies, more than 90% of participants experienced pregnancy pain. Greater linear increases and less negative quadratic change in maternal pain over time were associated with greater levels of postpartum depression, even when controlling for prenatal depressive symptoms. Interpreting both parameters together, pain that increased in late pregnancy, when normative patterns had either levelled off or begun to decline, was associated with greater levels of postpartum depression. CONCLUSION: A developmental trajectory of pain experience that did not subside after childbirth was associated with greater postpartum depressive symptoms, suggesting that atypical trajectories of pain may be a risk factor for postpartum depression.

RESUMEN

Maternal psychophysiological responses to toddlers' distress to novelty may have important implications for parenting during early childhood that are relevant to children's eventual development of social withdrawal and anxiety. Likely, these responses depend on intrapersonal, interpersonal, and contextual factors. The current study investigated the time course of respiratory sinus arrhythmia (RSA) across two laboratory novelty episodes, one low threat and one moderate threat, in 120 mothers of 2-year-old toddlers. Growth models tested context differences in and correlates of dynamic patterns of RSA. Dynamic patterns differed between tasks and according to mothers' perceptions of and distress about toddler shyness. Thus, changes in mothers' RSA across toddlers' interactions with novelty seem to depend on the context as well as how mothers perceive and respond to their toddlers' shyness.

RESUMEN

Reactivity to emotional information, measurable at the level of neural activity using event-related potentials, is linked to symptoms of affective disorders. Behavioral evidence suggests that contextual factors, such as social support, can alter emotional reactivity such that affective responding is normalized when social support is high. This possibility remains largely untested at the neural level, specifically through approaches that can offer insight into the mechanistic processes contributing to individual differences in emotional reactivity. Yet, such knowledge could be useful for prevention and intervention efforts, particularly with groups at risk for increased emotional reactivity, such as pregnant mothers for whom emotional distress predicts both maternal and child outcomes. Expectant mothers took part in a longitudinal study that tested whether the late positive potential (LPP), a neural index of reactivity to emotional information, was moderated by maternal perceptions of social support. In the third trimester of pregnancy, lower perceived social support was associated with an absence of a traditional LPP effect, which differentiates valenced from neutral stimuli. Findings suggest that perceptions of social support may normalize emotional processing at the neural level and highlight the potential importance of social support modulation of emotional reactivity during times of known biological change.

RESUMEN

Although the Children's Behavior Questionnaire (CBQ; Rothbart, Ahadi, Hershey, & Fisher, 2001) is the most popular assessment for childhood temperament, its psychometric qualities have yet to be examined using Item Response Theory (IRT) methods. These methods highlight in detail the specific contributions of individual items for measuring different facets of temperament. Importantly, with 16 scales for tapping distinct aspects of child functioning (195 items total), the CBQ's length can be prohibitive in many contexts. The detailed information about item functioning provided by IRT methods is therefore especially useful. The current study used IRT methods to analyze the CBQ's 16 temperament scales and identify potentially redundant items. An abbreviated "IRT form" was generated based on these results and evaluated across four independent validation samples. The IRT form was compared to the original and short CBQ forms (Putnam & Rothbart, 2006). Results provide fine-grained detail on the CBQ's psychometric functioning and suggest it is possible to remove up to 39% of the original form's items while largely preserving the measurement precision and content coverage of each scale. This study provides considerable psychometric information about the CBQ's items and scales and highlights future avenues for creating even more efficient high-quality temperament assessments.

RESUMEN

Maternal biological systems impact infant temperament as early as the prenatal period, though the mechanisms of this association are unknown. Using a prospective, longitudinal design, we found that maternal (N = 89) amplitudes of the late positive potential (LPP) in response to negative stimuli during the second, but not the third, trimester of pregnancy predicted observed and physiological indices of temperamental reactivity in infants at age 4 months. Maternal LPP was positively associated with observed infant fear and negatively associated with frontal EEG asymmetry and cortisol reactivity in infants at age 4 months. Results identify a putative mechanism, early in pregnancy, for the intergenerational transmission of emotional reactivity from mother to infant.

RESUMEN

The developmental psychobiology of self-regulation in childhood has received increasing attention in recent years. As a next step in advancing research and theorizing about the processes by which early biological correlates of self-regulation are forged, a more nuanced consideration of the contexts in which these phenomena are embedded is needed. This review synthesizes insights from distinct but complementary approaches to studying the developmental psychobiology of early self-regulation, focusing on the idea of context at different time scales. Three types of context that differ in temporal resolution are considered: (a) The temporally immediate contexts occurring within a structured challenge, including the baseline-to-task context of reactive psychobiology, the within-task context of dynamic change, and the post-task context of recovery from challenge. (b) The temporally moderate contexts of task type, including variants like the specific emotion that is under study and whether the task involves (or allows for) self-regulatory behaviors. (c) The temporally chronic contexts of important social relationships within which children are embedded and developing. Future research efforts that incorporate a more nuanced appreciation for the temporal resolution of contexts in developmental psychobiology will allow for novel tests and refinement of theories of self-regulation, as well as other domains of child development.

RESUMEN

There has been an unprecedented increase in the number of research studies employing event-related potential (ERP) techniques to examine dynamic and rapidly-occurring neural processes with children during the preschool and early childhood years. Despite this, there has been little discussion of the methodological and procedural differences that exist for studies of young children versus older children and adults. That is, reviewers, editors, and consumers of this work often expect developmental studies to simply apply adult techniques and procedures to younger samples. Procedurally, this creates unrealistic expectations for research paradigms, data collection, and data reduction and analyses. Scientifically, this leads to inappropriate measures and methods that hinder drawing conclusions and advancing theory. Based on ERP work with preschoolers and young children from 10 laboratories across North America, we present a summary of the most common ERP components under study in the area of emotion and cognition in young children along with 13 realistic expectations for data collection and loss, laboratory procedures and paradigms, data processing, ERP averaging, and typical challenges for conducting this type of work. This work is intended to supplement previous guidelines for work with adults and offer insights to aid researchers, reviewers, and editors in the design and evaluation of developmental research using ERPs. Here we make recommendations for researchers who plan to conduct or who are conducting ERP studies in children between ages 2 and 12, focusing on studies of toddlers and preschoolers. Recommendations are based on both data and our cumulative experience and include guidelines for laboratory setup, equipment and recording settings, task design, and data processing.

RESUMEN

Symptoms of attention-deficit/hyperactivity disorder (ADHD) and anxiety are common during adolescence and frequently co-occur. However, the genetic and environmental influences that underlie this co-occurrence are understudied. Using a large twin sample (N = 1,017), we examined cross-sectional genetic and environmental influences on ADHD and anxiety symptoms during childhood. We also explored whether these influences were shared with attentional control, a putative mechanism for symptom comorbidity. We found evidence for common genetic and nonshared environmental influences on the covariation among attentional control, ADHD, and anxiety symptoms, supporting the putative role of attentional control as a mechanism by which comorbid problems may develop. Genetic factors also accounted for symptom co-occurrence after controlling for covariation with attentional control, suggesting the presence of additional unmeasured mechanisms.
