Prediction of toddlers’ expressive language from maternal sensitivity and toddlers’ anger expressions: A developmental perspective

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.     

The association between maternal strategies and preschoolers' memory for location of objects

Using a Vygotskian theoretical framework and a social interaction design, we observed 30 middle-class North American mother–child dyads engaged in a location memory activity. The central aim of this investigation was to assess maternal and preschool strategy use employed during a memory for location task, and to determine which strategies are associated with preschooler accuracy of memory for location of objects. Results suggest that mothers are more apt to utilize labelling, encouragement, and guidance as opposed to location-specific assistance to their child during the task, and children are more apt to link the memory information to their real-life experiences, request help for assistance, and utilize self-regulatory speech. Implications of the research, suggestions for future research, and expansions of theoretical perspectives on the role of social interaction on preschool location memory performance, and educational implications are discussed.     

Mothers’ physical interventions in toddler play in a low-income,African American sample

This mixed method study examined 28 low-income African American mothers’ physical interventions in their 14-month-old toddlers’ play. Inductive methods were used to identify six physical intervention behaviors, the affect accompanying physical interventions, and apparent reasons for intervening. Nonparametric statistical analyses determined that toddlers experienced physical intervention largely in the context of positive maternal affect. Mothers of boys expressed highly positive affect while physically intervening more than mothers of girls. Most physically intervening acts seemed to be motivated by maternal intent to show or tell children how to play or to correct play deemed incorrect. Neutral affect was the most common toddler affect type following physical intervention, but boys were more likely than girls to be upset immediately after physical interventions. Physical interventions intended to protect health and safety seemed the least likely to elicit toddler upset.     

Linguistic and prosodic aspects of child-directed speech: The role of maternal child-rearing experiences

This study explored if the quality of mothers’ reported child-rearing experiences influences the prosodic and linguistic features of maternal child-directed speech. Lexical, syntactic, functional and prosodic aspects of maternal speech directed towards their 24-month-old children were examined. Results showed that mothers with different child-rearing histories differed in the ways they talked to their children. Mothers who recalled the caregiving they received during childhood as characterized by high levels of care and low levels of control, used a lexically and syntactically more complex speech and expressed more positive emotions. This kind of input seems to be more attuned with the typical growing skills of two-year-old children. Implications for the study of mother–infant relationship as well as for the study of child language development are addressed.     

父母心理控制与ODD症状儿童抑郁、攻击行为的关系

以北京市、山东省和云南省14所小学中的340名有对立违抗障碍(Oppositional Defiant Disorder, ODD)症状的儿童及其158名班主任为被试, 收集了儿童自己填写的父母心理控制、自尊、抑郁量表, 班主任评估的儿童攻击行为量表, 用以考察父亲与母亲心理控制对ODD症状儿童抑郁、攻击行为的不同影响, 以及自尊在其中的中介作用和儿童性别的调节作用。结果发现:(1)与有ODD症状的女孩相比, 具有ODD症状的男孩人数更多, 抑郁、攻击行为问题更为严重, 自尊也更差;(2)父亲对男孩的心理控制显著多于女孩, 而母亲对男孩、女孩的心理控制没有显著差异;(3)父亲和母亲心理控制与ODD症状儿童的抑郁、攻击行为都呈显著正相关且父亲心理控制能显著预测儿童的抑郁和攻击行为, 而母亲心理控制能显著的预测攻击行为;(4)自尊在父亲心理控制与ODD症状儿童的抑郁、母亲心理控制与儿童的攻击行为之间均起部分中介作用, 在父亲心理控制与儿童的攻击行为、母亲心理控制与儿童的抑郁之间均起完全中介作用。     

Dyadic synchrony among young Latina mothers and their toddlers: The role of maternal and child behavior

Synchronous interactions are an important indicator of parent-child relationship quality with positive implications for child development. Latina adolescent mothers face several demographic challenges that place them at risk for less synchronous interactions. To identify factors that may facilitate more optimal parent-child relationships in this population, our study examined maternal sensitivity and children’s behavioral styles as joint predictors of dyadic synchrony among young Latina mothers and their toddlers. Mother-toddler dyads (N = 170) were observed interacting across different tasks, and toddlers’ behavior was observed during the administration of a developmental test. Results of multivariate regressions revealed additive effects of maternal sensitivity and child behavioral styles (i.e., dysregulation and positive attentional control). Maternal sensitivity related to higher dyadic synchrony for the entire sample. Positive attentional control was related to higher dyadic synchrony for mother-daughter dyads only. Although no gender differences in dyadic synchrony or the behavior style variables emerged, the relative contribution of maternal and child factors differed by child gender, suggesting that mothers may have responded differently to similar behavior and affect displayed by boys and girls. The findings provide insights regarding factors that contribute to dyadic synchrony in this understudied population and emphasize the need to consider child gender when studying parent-child interactions in young Latina families.     

The role of oxytocin in early mother-infant interactions: Variations in maternal affect attunement

The aim of the present research was to investigate the relationship between oxytocin and maternal affect attunement, as well as the role of affect attunement in the relationship between oxytocin and infant social engagement during early mother-infant interactions. Forty-three mother-infant dyads participated in the present study when infants were 4 months. They were observed during (1) a situation where no communication took place and (2) a natural interaction between mother and infant. During this procedure, three saliva samples from mothers and their infants were collected to determine their levels of oxytocin at different time points. Maternal affect attunement (maintaining attention, warm sensitivity) and infant interactive behaviors (gaze, positive, and negative affect) were coded during the natural interaction. Results indicated that overall maternal oxytocin functioning was negatively related to her warm sensitivity, while infant oxytocin reactivity together with maternal affect attunement were associated with infant positive social engagement with their mothers. Specifically, infant oxytocin reactivity was significantly related to their gazes at mother, but only for infants of highly attuned mothers. These results point to the complex role oxytocin plays in parent-infant interactions while emphasizing the need to analyze both overall oxytocin functioning as well as reactivity as different indices of human affiliative behavior.     

Emotional and behavioral problems in children of depressed mothers: a school-based study in Southern Brazil

The present study aimed to verify the association between maternal depression and emotional and behavioral problems in school children in Pelotas, Southern Brazil, considering that maternal depression increases children’s vulnerability for developing psychiatric disorders. This is a cross-sectional study with a school-based sample conducted between August 2015 and November 2016 and it is part of a major project entitled ‘Healthy Childhood in Context: A Multidisciplinary Investigation’. Schoolchildren aged between 7 and 8 years and one of their respective parents or a primary caregiver were included in the study. Maternal depression was assessed using the Mini International Neuropsychiatric Interview (MINI). The presence of emotional and behavioral problems in children was verified by the Strengths and Difficulties Questionnaire (SDQ) – parents version. Children of depressed mothers exhibited higher mean scores in all SDQ domains and in the total score when compared to children of non-depressed mothers. Lower socio-economic status was also associated with higher SDQ scores. Our results showed the effects of both maternal depression and poverty on children emotional and behavioral problems, which evidence the need for child mental health preventive care, and free quality assistance for both mothers and their children.     

Individual differences in non-clinical maternal depression impact infant affect and behavior during the still-face paradigm across the first year

Maternal depression can significantly impact mothers’ sensitivity to their infants’ needs as well as infants’ social and emotional development. The still-face paradigm (SFP) is widely used to assess infants’ understanding of the contingency between their own behavior and that of their caregivers, as well as infants’ ability to self-regulate arousal levels during sudden changes in maternal responsiveness. Infants of clinically depressed mothers display blunted levels of negative affect compared to infants of non-depressed mothers during the still-face (SF) phase. However, little is known about whether individual differences in elevated, non-clinical levels of maternal depression similarly affect mother-infant interactions. The current study examines the longitudinal effects of non-clinical maternal depression on infant and maternal behaviors during the SFP. Infants (N = 63) were assessed at 5 and 9 months and maternal depression was assessed at 5 months using the Beck Depression Inventory (BDI). Infants of mothers with elevated levels of depression displayed less negative engagement during the SF phase compared to infants of mothers with lower levels of depression. This effect was present at 5 months, but not at 9 months. Findings demonstrate that non-clinical levels of maternal depressive symptomatology can have a significant impact on infants’ affective regulation during the first half of the first year of life, but this does not necessarily have a long-lasting influence later in infancy. Interventions may want to target mothers with non-clinical depression to promote healthy infant social and emotional development.
