Mother-child memory conversations are a nuanced and important factor in children\'s memory development. The current study focuses on maternal characteristics that are related to individual differences in maternal elaborative style. It also examines the role of maternal elaborative style in children\'s elaborativeness in the context of reminiscing and recounting. Two hundred and nine Turkish mothers (Mage = 36.32, SD = 4.99) and their 5- to 6-year-olds (Mage in months = 66.88, SD = 4.04) (110 girls, 99 boys) participated in the current study. Results revealed that maternal individuation and balanced self-construal type predicted maternal elaborativeness, which in turn predicted child elaborativeness in reminiscing and recounting. Yet, such a relation was not observed for maternal attachment styles or sensitivity. Findings suggested the importance of maternal individuation and balanced self-construal for mothers\' and children\'s elaborativeness in memory conversations.

Attachment theorists claim that the quality of parental support is internalized as a mental representation of early relationship experiences. Increasingly, the content of attachment representations is evaluated by studying the extent to which adults demonstrate knowledge of the secure base script, either in the context of the Attachment Script Assessment (ASA) or during the Adult Attachment Interview (AAIsbs). Preliminary evidence from a high-risk sample showed that AAIsbs was more strongly associated with the quality of antecedent caregiving than was the more traditional approach to the measurement of adult attachment focused on the coherence of adults\' AAI discourse (Waters, et al., 2017). Drawing on new coding of data from the NICHD Study of Early Child Care and Youth Development (SECCYD), we found that AAIsbs around age 18 years was significantly predicted by observations of maternal (r = .21) and paternal (r = .12) sensitivity assessed prospectively through age 15 years, and with attachment security in the first three years of life (r =.08). AAIsbs was also associated with existing measures of adult attachment (rs = .31-.42). Pre-registered analyses revealed that AAIsbs performed in a manner roughly comparable to traditional, though more labor intensive approaches to coding the AAI. Based on all available evidence from the SECCYD and the pragmatic challenges and advantages of different narrative methods for assessing adult attachment representations (Booth-LaForce & Roisman, 2014; Steele et al., 2014), researchers seeking to measure attachment representations should strongly consider the strengths of the ASA in term of practicality, performance, and adaptability to various age groups across development (Waters & Waters, 2021).

Previous research and theory indicate an importance of the quality of the early caregiving environment in the development of self-regulation. However, it is unclear how attachment security and maternal sensitivity, two related but distinct aspects of the early caregiving environment, may differentially predict self-regulation at school start and whether a distinction between hot and cool executive function is informative in characterizing such predictions through mediation. In a 5-year longitudinal study (n = 108), we examined these associations using measures of maternal sensitivity and attachment security at 10-12 months, executive function at 4 years, and self-regulation at 6 years. Surprisingly, and despite methodological rigor, we found few significant bivariate associations between the study variables. We found no credible evidence of a longitudinal association between maternal sensitivity or attachment security in infancy and self-regulation at 6 years, or between executive function at 4 years and self-regulation at 6 years. The lack of bivariate longitudinal associations precluded us from building mediation models as intended. We discuss our null findings in terms of their potential theoretical implications, as well as how measurement type, reliability, and validity, may play a key role in determining longitudinal associations between early caregiving factors and later self-regulation and related abilities. RESEARCH HIGHLIGHTS: The early caregiving environment has been implicated in the development of later self-regulation, which includes more basic skills, such as hot and cool executive functions (EF). In a 5-year longitudinal study, with a sample of 108 children, we rigorously measured aspects of early caregiving, EF, and self-regulation. We found no significant longitudinal associations between early caregiving and self-regulation at 6 years, nor between EF at 4 years and self-regulation at 6 years. These null results highlight the complexity of modeling self-regulation development and raise critical questions about general methodological conventions within self-regulation development research.

Infants\' hypothalamic-pituitary-adrenocortical (HPA) axis responses to acute stressors are theorized to be shaped by parents\' sensitive responsiveness to infants\' cues. The strength and direction of the association between maternal sensitivity and infants\' HPA responses may depend on the context in which maternal sensitivity is observed and on broader environmental sources of stress and support. In this preregistered study, we used data from 105 mothers and their 7-month-old infants to examine whether two empirically identified forms of contextual stress-poor maternal psychosocial wellbeing and family socioeconomic hardship-moderate the association between maternal sensitivity and infants\' cortisol responses to the Still-Face Paradigm (SFP). Results indicated that maternal sensitivity during the free play and family socioeconomic hardship interacted to predict infants\' cortisol responses to the SFP. Specifically, maternal sensitivity during this non-distressing interaction was negatively associated with cortisol responses only among infants whose mothers were experiencing relatively high socioeconomic hardship. Exploratory analyses revealed that poor maternal psychosocial wellbeing was positively associated with overall infant cortisol production during the SFP. Altogether, these findings suggest that experiences within early parent-infant attachment relationships and sources of contextual stress work together to shape infant HPA axis activity.

Challenges with childhood emotion regulation may have origins in infancy and forecast later social and cognitive developmental delays, academic difficulties, and psychopathology. This study tested whether markers of emotion dysregulation in infancy predict emotion dysregulation in toddlerhood, and whether those associations depended on maternal sensitivity. When children (N = 111) were 7 months, baseline respiratory sinus arrhythmia (RSA), RSA withdrawal, and distress were collected during the Still Face Paradigm (SFP). Mothers\' reports of infant regulation and orientation and maternal sensitivity were also collected at that time. Mothers\' reports of toddlers\' dysregulation were collected at 18 months. A set of hierarchical regressions indicated that low baseline RSA and less change in RSA from baseline to stressor predicted greater dysregulation at 18 months, but only for infants who experienced low maternal sensitivity. Baseline RSA and RSA withdrawal were not significantly associated with later dysregulation for infants with highly sensitive mothers. Infants who exhibited low distress during the SFP and who had lower regulatory and orienting abilities at 7 months had higher dysregulation at 18 months regardless of maternal sensitivity. Altogether, these results suggest that risk for dysregulation in toddlerhood has biobehavioral origins in infancy but may be buffered by sensitive caregiving.

Decades have passed since the controversy regarding the putative risks of childcare for mother-child attachment broke out. Yet, some uncertainty remains, as relevant studies have produced inconsistent evidence. Some have proposed that those conflicting findings may be due to the fact that the effects of childcare are conditioned on parenting. Accordingly, this study examined whether relations between childcare participation and mother-child attachment vary according to maternal sensitivity and autonomy support. In this sample of 236 mother-child dyads, there was no indication of main effects of childcare participation on attachment. There were, however, some interactive effects, such that the children who showed the least secure attachment behaviors were those who did not attend childcare and had either less sensitive or less autonomy-supportive mothers. The findings suggest that the effects of childcare on mother-child attachment are best understood in light of the parenting children receive at home.

Previous studies underscore the importance of social interactions for child language development-particularly interactions characterized by maternal sensitivity, infant-directed speech (IDS), and conversational turn-taking (CT) in one-on-one contexts. Although infants engage in such interactions from the third month after birth, the prospective link between speech input and maternal sensitivity in the first half year of life and later language development has been understudied. We hypothesized that social interactions embodying maternal sensitivity, IDS and CTs in the first 3 months of life, are significantly associated with later language development and tested this using a longitudinal design. Using a sample of 40 3-month-old infants, we assessed maternal sensitivity during a structured mother-infant one-on-one (1:1) interaction based on a well-validated scoring system (the Coding Interactive Behavior system). Language input (IDS, CT) was assessed during naturally occurring interactions at home using the Language ENvironment Analysis (LENA) system. Language outcome measures were obtained from 18 to 30 months of age using the MacArthur-Bates Communicative Development Inventory. Three novel findings emerged. First, maternal sensitivity at 3 months was significantly associated with infants\' productive language scores at 18, 21, 24, 27, and 30 months of age. Second, LENA-recorded IDS during mother-infant 1:1 interaction in the home environment at 3 months of age was positively correlated with productive language scores at 24, 27, and 30 months of age. Third, mother-infant CTs during 1:1 interaction was significantly associated with infants\' productive language scores at 27 and 30 months of age. We propose that infants\' social attention to speech during this early period-enhanced by sensitive maternal one-on-one interactions and IDS-are potent factors in advancing language development.

Maternal insensitivity to children\'s emotional distress (e.g., expressions of sadness or fearfulness) is one mechanism through which maternal alcohol dependence may increase children\'s risk for psychopathology. Although emotion dysregulation is consistently associated with psychopathology, it remains unclear how or why alcohol dependence\'s effects on caregiving responses to children\'s distress may impact children\'s emotion regulation over time, particularly in ways that may engender risks for psychopathology. This study examined longitudinal associations between lifetime maternal alcohol dependence symptoms, mothers\' insensitivity to children\'s emotional distress cues, and children\'s emotional reactivity among 201 mother-child dyads (Mchild age = 2.14 years; 56% Black; 11% Latino). Structural equation modeling analyses revealed a significant mediational pathway such that maternal alcohol dependence predicted increases in mothers\' insensitivity to children\'s emotional distress across a one-year period (β = .16, p = .013), which subsequently predicted decreases in children\'s emotional reactivity one year later (β = -.29, p = .009). Results suggest that mothers with alcohol dependence symptoms may struggle to sensitively respond to children\'s emotional distress, which may prompt children to suppress or hide their emotions as an adaptive, protective strategy. The potential developmental benefits and consequences of early, protective expressive suppression strategies are discussed via developmental psychopathology frameworks.

In Wertz et al. (2019), parents\' polygenic scores of educational attainment (PGS-EA) predicted parental sensitive responses to the child\'s needs for support, as observed in a dyadic task (i.e., observed sensitivity). We aimed to replicate and expand these findings by combining longitudinal data, child genotype data and several polygenic scores in the Generation R Study. Mother-child dyads participated in two developmental periods, toddlerhood (14 months old; n = 648) and early childhood (3-4 years old, n = 613). Higher maternal PGS-EA scores predicted higher observed sensitivity in toddlerhood (b = 0.12, 95% CI 0.03, 0.20) and early childhood (b = 0.16, 95% CI 0.08, 0.24). Child PGS-EA was significantly associated with maternal sensitivity in early childhood (b = 0.11, 95% CI 0.02, 0.21), and the effect of maternal PGS-EA was no longer significant when correcting for child PGS-EA. A latent factor of PGSs based on educational attainment, intelligence (IQ) and income showed similar results. These polygenic scores might be associated with maternal cognitive and behavioral skills that help shape parenting. Maternal PGSs predicted observed sensitivity over and above the maternal phenotypes, showing an additional role for PGSs in parenting research. In conclusion, we replicated the central finding of Wertz et al. (2019) that parental PGS-EA partially explains parental sensitivity. Our findings may be consistent with evocative gene-environment correlation (rGE), emphasizing the dynamic nature of parenting behavior across time, although further research using family trios is needed to adequately test this hypothesis.

During early childhood, play develops through levels of sensory exploration and manipulation, to functional activities and during the second year of life to the level of pretend and symbolic play. However, little is known about the factors contributing to individual variations in the development of play. The present study investigated associations between maternal sensitivity and play conditions with different ways of engaging and participating and children\'s development of pretend play. Participants were 64 primiparous mothers and their 30-months-old children. Sensitivity was assessed using the Coding Interactive Behavior (CIB) coding system, and children\'s play was coded using the 12 Step Play Scale. Analyses showed no significant associations between sensitivity and children\'s play development but a play condition introducing a story stem was associated with a higher developmental play level and longer duration of pretend play compared to free interactive play. The findings suggest that the use of a story stem may promote pretend play in interactive settings with the mother.
