Description
The main objective of this study was to use a genetically-informative design to examine the putative influences of maternal perceived prenatal stress, obstetrical complications, and gestational age on infant dysregulation, competence, and developmental maturity. Specifically, whether or not prenatal and obstetrical environmental conditions modified the heritability of infant outcomes was examined. A total of 291 mothers were interviewed when their twin infants were 12 months of age. Pregnancy and twin birth medical records were obtained to code obstetrical data. Utilizing behavioral genetic models, results indicated maternal perceived prenatal stress moderated genetic and environmental influences on developmental maturity whereas obstetrical complications moderated shared environmental influences on infant competence and nonshared environmental influences on developmental maturity. Gestational age moderated the heritability and nonshared environment of infant dysregulation, shared and nonshared environmental influences on competence, and nonshared environmental influences on developmental maturity. Taken together, prenatal and obstetric conditions were important nonlinear influences on infant outcomes. An evolutionary perspective may provide a framework for these findings, such that the prenatal environment programs the fetus to be adaptive to current environmental contexts. Specifically, prenatal stress governs gene expression through epigenetic processes. Findings highlight the utility of a genetically informative design for elucidating the role of prenatal and obstetric conditions in the etiology of infant developmental outcomes.

Description
This study aimed to develop a measurement model for executive function (EF) in middle childhood for a low-income Mexican American sample and to elucidate dynamic change processes among measurable developmental correlates of EF during infancy and early toddlerhood as predictors of later higher-order EF abilities. Drawing from developmental theory and a model of neurovisceral integration, surges in neurocognitive regulatory abilities may be supported by both previous and concurrent changes in physiological functioning and engagement in reciprocal social relationships. Utilizing recent methodological innovations, the current study moved beyond traditional growth models to evaluate possible points of attenuation and acceleration in dyadic reciprocity and vagal functioning over time as well as dynamic associations between these unfolding developmental processes. Data were collected from 322 low-income Mexican American children in the home at 24 weeks and in a laboratory space at ages 1, 1.5, 2, 3, and 6 years. A parent-report measure of executive function also was collected over the phone between child age 7.5 and 9 years. Results suggested that, in this sample, EF was best modeled at child age 6 years as a unidimensional construct. Findings also supported the importance of earlier dyadic reciprocity for later EF, but there was a lack of evidence supporting the theorized link between EF and earlier vagal functioning and codevelopment of vagal functioning and dyadic reciprocity. This study highlights the importance of including dyadic measures of parent-child contingencies in studies of EF development and, from a clinical perspective, the potential use of relationship-based, dyadic intervention and prevention models to support crucial development of EF skills central to everyday adaptive functioning.

Description
A cornerstone of children’s socio-cognitive development is understanding that others can have knowledge, thoughts, and perceptions that differ from one’s own. Preschool-aged children often have difficulty with this kind of social understanding, i.e., they lack an explicit theory of mind. The goal of this dissertation was to examine the role mental state language as a developmental mechanism of children’s early understanding of their own mental states (i.e., their introspective ability). Specifically, it was hypothesized that (1) parents’ ability to recognize and appropriately label their children’s mental states and (2) children’s linguistic ability to distinguish between their mental states shapes the development of children’s introspective ability. An initial prediction of the first hypothesis is that parents should recognized differences in the development of children’s self- and other-understanding in order to better help their children’s introspective development. In support of this prediction, parents (N = 400, Mage = 58 months, Range = 28-93 months) reported that children’s understanding of their own knowledge was greater than children’s understanding of others’ knowledge. A prediction of the second hypothesis is that children’s linguistic ability to distinguish between and appropriately label their own mental states should determine their ability to make fined grained judgments of mental states like certainty. In support of this prediction, children’s (N = 197, Mage = 56 months, Range = 36-82 months) ability to distinguish between their own knowledge and ignorance states was associated children’s ability to engage in uncertainty monitoring. Together, these findings provide support for the association between children’s linguistic environment and ability and their introspective development.

Description
The goal of this study is to contribute to the understanding of Mexican-American three- to five-year-old children’s effortful control (EC) and negative emotionality (NE) development by examining whether Mexican-American adolescent mothers’ parenting transacts with their three- to five-year-old children’s EC and NE and by exploring whether mothers’ familism acts as a protective factor. I hypothesized that mothers’ harshness and warmth would transact with EC and NE over time. I further hypothesized that mothers’ familism values would (a) positively predict mothers’ warmth and negatively predict mothers’ harshness, and (b) act as a buffer between low EC and high NE, and high harshness and low warmth. These hypotheses were tested within a sample of Mexican-American adolescent mother-child dyads (N = 204) and assessed longitudinally when children were 36, 48, and 60 months. Mothers were predominantly first generation (i.e., mothers’ parents were born in Mexico; 67%) and spoke English (65%). When children were 36 months, average family income (i.e., wages, public assistance, food stamps) was $24,715 (SD = $19,545) and mothers had started community college (13%) or completed high school/GED (30%), 11th grade (19%), 10th grade (8%), or less than 9th grade (14%). In this sample, transactions between harshness or warmth and EC or NE were not found, but a bidirectional association between NE and harshness was found. Familism marginally negatively predicted harshness, but not warmth. Familism moderated the relation between NE and harshness such that there was only a negative relation between NE and harshness when familism was high. However, familism did not moderate the relations between NE and warmth, or EC and harshness or warmth. The results of this study are discussed with respect to (a) current methodological limitations in the field, such as the need to test or develop parent-report measures of Mexican-American children’s temperament and value-driven socialization goals, (b) future avenues for research, such as person-centered studies of clusters of mothers’ values and how those relate to clusters of parenting behaviors, and (c) implications for interventions addressing parenting behavior of adolescent mothers.

Description
The ability to self-regulate is arguably the single most important skill a child develops early in life. Self-regulation skills are consistently linked to indices of health, success, and wellbeing. The predominating perspective in self-regulation developmental research has emphasized the role of the early caregiving environment, specifically maternal characteristics and behavior, in shaping infants’ emerging regulatory skills. Using two complementary studies, this dissertation draws from a longitudinal sample of 322 low-income, Mexican American mother-infant dyads to better understand mothers’ and infants’ unique roles in contributing to emerging infant regulatory processes. The first study explores the unique contributions of intrinsic (i.e., infant gaze) and extrinsic (i.e., maternal gaze) factors in understanding infant dysregulated emotion and behavior during mother-infant interactions. Using actor partner interdependent models (APIMs), the role of infant and maternal gaze in understanding infant dysregulation were examined longitudinally across three mother-infant interaction tasks (i.e., soothing, teaching, and peekaboo), as well as within task. The expected relations among gaze and dysregulation did not emerge in the longitudinal model; however, differential patterns of associations emerged by task. Findings are discussed within the intersection of risk, culture, and the dyadic interaction context.
The second study connects patterns of specific maternal behaviors (i.e., acknowledging, gaze, vocal appropriateness, appropriate range of affect, consistency of style, resourcefulness, and touch) associated with maternal sensitivity to infant cortisol reactivity and recovery. Latent profile analysis (LPA) revealed four distinct combinations of maternal sensitivity behaviors. One pattern emerged as a risk profile—differentiated by higher maternal stress—and was associated with significantly more infant cortisol recovery compared to other profiles. Both studies offer a more nuanced understanding of the respective roles of infant and maternal factors in the development of self-regulation. Further explication of developmental processes involved in early regulatory functioning has implications for advancing both scientific knowledge and improved targeting of prevention and early intervention efforts to promote optimal child outcomes, particularly in populations that at increased risk for developmental psychopathology.

Description
To explore subtypes of social withdrawal in different sociocultural contexts, concurrent social, school, and academic correlates of shyness and unsociability were examined in 93 urban (Mage = 14.05, SD = 0.86 years) and 136 rural (Mage = 14.39, SD = 0.69 years) seventh and eighth graders from Liaoning, China. Adolescents' shyness and unsociability were assessed with self-, peers’, and teachers’ reports. Peer-group relationships (acceptance, rejection, and exclusion) were obtained from peer nominations. Adolescents reported perceived friendship quality (positive friendship quality, conflict and betrayal) and school attitudes (school liking and avoidance). Teachers rated students' academic engagement and performance. Academic achievement (exam grades) also was obtained from school records.
According to factor and correlational analyses, shyness and unsociability emerged as distinct, but positively related, constructs, within each informant. Cross-informant agreements on shyness and unsociability were low to moderate, especially between teachers' and self- or peers' reports. Urban-rural differences were expected in the associations of shyness, but not of unsociability, with the correlates, but the hypotheses were not supported with multiple-group (urban vs. rural) path models. In the combined (urban and rural) sample, shyness was associated with negative peer relationships, low friendship quality, and negative school attitudes (for self- but not peer-reported shyness), but was unrelated to academic correlates. Self-reported unsociability related negatively to positive friendship quality and positively to academic achievement, but was unrelated to other adjustment correlates. Peer-reported unsociability, however, was associated with negative peer relationships, less positive friendship quality, low school liking, low academic performance, and low academic achievement.
The study was an initial step towards understanding subtypes of social withdrawal and adjustment correlates in various domains among Chinese adolescents living in different social contexts. The lack of urban-rural differences was not consistent with the contextual-development theory. Like their Western peers, shy Chinese adolescents were at risk for relational and school adjustment problems, but they did not have academic difficulties. Unsociable Chinese adolescents also tended to have poor adjustment at school, including relational problems with peers and friends, negative school attitudes, and academic difficulties, but only when they were perceived as unsociable by peers, rather than themselves.

Description
Theoretical models support conceptualizing parent-child relationships as reciprocal and transactional with each person exerting influence on the other’s behaviors and the overall quality and valence of the relationship across time. The goals of this study were twofold: 1) determine whether there were reciprocal relations in maternal hostility and child negativity across early and middle childhood, and 2) investigate whether individual characteristics (i.e., child temperamental anger and frustration and maternal neuroticism) moderated relations found in goal one. Data were from the Study of Early Child Care and Youth Development. Empirical support was found for conceptualizing mother-child interactions as reciprocal. Maternal hostility was related to a decrease in the probability children would exhibit negative behaviors during mother-child interactions measured approximately two years later. Child negativity was also associated with a significant decrease in the probability mothers would display future hostility.
Child temperamental anger and frustration was found to moderate reciprocal relations across all three parent-to-child cross-lagged paths. Children scoring high on a dispositional proclivity to react with anger and frustration were more likely to avoid maternal hostility, via a significant decrease in negativity, across time. Moderation was also supported in two of three child-to-parent lagged paths. Finally, maternal neuroticism moderated the reciprocal effects during early childhood, such that more neurotic mothers were more likely to demonstrate a decrease in the probability of hostility relative to mothers scoring lower on neuroticism. This affect was attenuated in middle childhood, with patterns becoming similar between mothers scoring high and low on neuroticism. Moreover, children of less neurotic mothers were more likely to demonstrate a decrease in the probability of exhibiting negativity from 36 to 54 months compared to children of more neurotic mothers. This effect also attenuated with patterns becoming negative at the grade 1 to grade 3 lag. Overall, the results from this study supported a transactional model of parent-child relationships, were consistent with the motivation literature, did not support a coercive process of interaction when the sample and measurement paradigm were low-risk, and generally suggested parents and children have an equal influence on the relational processes investigated from early to middle childhood.

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
The goal of this study was to illuminate areas of strength within a sample of Hispanic, Spanish-speaking children (n = 446) from the early head start research and evaluation project, a multi method, multi reporter longitudinal study that involved children starting at 14-months through pre-kindergarten, with a 5th grade follow up assessment. A longitudinal path model examined relations between external factors (i.e., parent warmth and responsivity, home cognitive and language environment, child-directed speech), and internal factors (i.e., child self-regulation), and Spanish language before kindergarten, and English language at 5th grade. In addition to direct paths, indirect paths were included from external factors to language outcomes through self-regulation and Spanish language. After controlling for important demographic variables, analyses indicated that parents’ warmth and responsivity was directly related to children’s self-regulation and children’s English language proficiency in 5th grade. Home environment and self-regulation were directly related to children’s Spanish language proficiency. Children’s Spanish language proficiency was directly related to English language proficiency. Significant indirect effects emerged between parent warmth and responsivity to both Spanish and English language via children’s self-regulation. Results additionally evidenced significant indirect paths from home environment and self-regulation to English language through Spanish language. Direct paths between parent warmth/responsivity and Spanish language, home environment and English language, and child-directed speech and child regulation, Spanish language, and English language were not significant. Implications include current and future interventions targeted at bolstering parent-child interactions and regulation skills and to promote early educational programs supportive of both heritage and second languages.
