Description
Examining processes that characterize the ebb and flow of emotions offers insight into how infants modulate their own emotional experience as well as how both mothers and infants jointly regulate their emotional states. Drawing from polyvagal theory, which posits that vagal tone supports the capacity to quickly, flexibly, and adaptively respond to contextual demands (Porges, 2003, 2007), I hypothesized that infants with greater vagal tone (indexed by respiratory sinus arrhythmia; RSA) would show stronger evidence of emotion regulation and coregulation processes during free play and a frustrating task at 24 weeks child age. To evaluate these hypotheses, I used dynamic structural equation modeling (DSEM; Asparouhov, Hamaker, & Muthén, 2018) to examine biologically-based differences in second-by-second infant emotion regulation (equilibria, volatility, carryover, and feedback loops in positive and negative affect engagement) and mother- and infant-driven coregulation processes, among a sample of 210 low-income, Mexican-origin mother-infant dyads. Results offered evidence of both mother-driven and infant-driven emotion coregulatory processes during free play, which did not differ based on infant RSA. Results offered limited support for RSA-based differences in infant self-regulation processes during the teaching task, such that infants with below average RSA tended to respond to increased negative affect with subsequent increases in positive affect engagement. Prenatal maternal depressive symptoms also accounted for greater infant emotional volatility and weaker mother-driven emotion coregulation. Results highlight the unique roles mothers and infants play in achieving emotion regulation, as well as between-dyad differences in these processes, suggesting multiple pathways towards resilience among low-income, Mexican-origin families.

Description
Ecological systems theory argues that multiple nested systems impact child development. This study used a moderated mediation pathway to examine whether presence of a grocery store, number of fast-food restaurants, outdoor play space, and outdoor play safety affected children’s blood pressure and BMI through variation in healthy family habits. Maternal perceived neighborhood social and cultural cohesion was examined as a moderator of the mediated effect. Data was collected from 214 mother–child dyads via biological measurement, maternal-report surveys, and geocoding of children’s neighborhoods using Google Earth. Zero-order correlations showed that higher number of fast-food restaurants in a child’s neighborhood was correlated with less engagement in healthy family habits and lower child BMI z-score. In all models, higher neighborhood social and cultural cohesion was associated with more engagement in healthy family habits. No statistically significant mediated effects or moderation of the mediated effects were found. Future directions may aim to identify which objective neighborhood environment indicators influence child health and what are potential variables mediating the relation.

Description
The purpose of this study was to examine the effects of two positive discrete emotions, awe and nurturant love, on implicit prejudices. After completing an emotion induction task, participants completed Implicit Association Test blocks where they paired photos of Arab and White individuals with "good" and "bad" evaluations. We hypothesized that nurturant love would increase the strength of negative evaluations of Arab individuals and positive evaluations of White individuals, whereas awe would decrease the strength of these negative evaluations when compared to a neutral condition. However, we found that both awe and nurturant love increased negative implicit prejudices toward Arab individuals when compared to the neutral condition.

Description
Research demonstrates that maladaptive eating (e.g., restriction, disinhibition) and persistent depressive symptoms often co-occur and may reinforce each other over time. However, little is known regarding the etiology of early maladaptive eating and depressive symptoms among Mexican American children and how cultural orientation impacts co-occurrence. This study aimed to map the emerging structure of maladaptive eating–depression symptom networks, identify early dysfunctional mechanisms (i.e., symptoms) that maintain network structure, and explore how cultural orientation influences mechanisms. The sample included 263 low-income Mexican American children, assessed at 6-, 7.5-, and 9-years-old via maternal report. Mothers completed surveys on child eating, depressive symptoms, and cultural orientation. Data was analyzed using regularized partial correlation, Ising, and mixed graphical network models. Results showed that maladaptive eating networks were invariant over time. Central maladaptive eating symptoms were related to food responsiveness. Depressive symptom and combined networks were not stable enough for interpretation. Sadness and thoughts of worthlessness/inferiority emerged as central depressive symptoms at age 9. No bridge symptoms or moderated effects were large enough for interpretation. This study is the first of its kind to examine associations between eating and depressive symptoms among Mexican American children using network analysis. Results provide etiological information on the structure of co-occurring eating and depressive symptoms across late childhood and provide direction towards optimal prevention targets among this group.
