通过对138名学步儿童及其母亲的观察研究,分析儿童的不顺从行为与亲子互动之间的关系。结果表明:(1)在亲子互动中,母亲的言语策略多于身体策略。(2)母亲的模糊言语显著地正向预测儿童的反抗,母亲的远处身体指导显著地正向预测消极不顺从。(3)母亲的反应性与明晰言语、模糊言语、积极身体指导和远处身体指导正相关,与严厉言语和消极身体指导负相关。(4)儿童反应性负向预测消极不顺从和拒绝/协商行为。     

Responsive Parenting in the Second Year: Specific Influences on Children's Language and Play

In two longitudinal studies, relations between dimensions of maternal responsiveness at 13 months and children's language and play abilities at 13 and at 20 months were examined. We characterized mothers' responsive exchanges by assessing the targets of maternal responses (i.e. what child activities mothers respond to) and the verbal contents of maternal responses (i.e. what mothers said when they responded), and we asked whether subtypes of responsiveness would relate differentially to children's language and play abilities. In general, maternal responsiveness to children's vocalizations predicted children's language, and maternal responses to children's play predicted children's play. These findings suggest that maternal responsiveness can be profitably categorized into subtypes that relate to domains of child outcomes in specialized ways. The specific nature of mother–child associations in the domains of early language and play is discussed. © 1996 John Wiley & Sons, Ltd.     

A longitudinal intergenerational analysis of executive functions during early childhood

Despite the importance of executive function (EF) in both clinical and educational contexts, the aetiology of individual differences in early childhood EF remains poorly understood. This study provides the first longitudinal intergenerational analysis of mother–child EF associations during early childhood. A group of children and their mothers (n = 62) completed age‐appropriate EF tasks. Mother and child EFs were modestly correlated by 24 months of age, and this association was stable through 48 months. Importantly, maternal–child EF associations were still robust after controlling for verbal ability (potential indicator of verbal/crystallized intelligence) and maternal education (correlate of socio‐economic status and verbal intelligence). Potential implications of these findings as well as underlying mechanisms of the maternal–child EF association (gene–environment interplay) are discussed.     

Interrelations between maternal smoking during pregnancy,birth weight and sociodemographic factors in the prediction of early cognitive abilities

Maternal prenatal smoking, birth weight and sociodemographic factors were investigated in relation to cognitive abilities of 1544 children (aged 3.5 years) participating in the Québec Longitudinal Study of Children's Development. The Peabody Picture Vocabulary Test (PPVT) was used to assess verbal ability, the Wechsler Preschool and Primary Scale of Intelligence‐Revised (WPPSI‐R) block design test to assess visuospatial ability, and the Visually Cued Recall (VCR) task to assess short‐term memory. Prenatal smoking was related to performance on the WPPSI‐R, the PPVT, and the VCR, although it did not independently predict any cognitive ability after maternal education was taken into account. Birth weight was a more robust predictor of all outcome measures and independently predicted VCR‐performance. Birth weight interacted significantly with family income and maternal education in predicting visuospatial ability, indicating a greater influence of birth weight under relatively poor socio‐economic conditions. Parenting and family functioning mediated associations between maternal education/family income and cognitive task performance under different birth weight conditions, although there were indications for stronger effects under relatively low birth weight. We conclude that investigations of moderating and mediating effects can provide insights into which children are most at risk of cognitive impairment and might benefit most from interventions.

Antecedents of information-processing skills in infants: Habituation, novelty responsiveness, and cross-modal transfer

Three skills which characterize cognitive functioning in human infants in the middle of the first year of life—habituation, novelty responsiveness, and cross-modal transfer—predict mental ability in later childhood. Antecedents of each skill at 5 months postnatal were examined in a short-term prospective longitudinal study of infant ability and maternal intelligence and interaction style. Infant perceptuocognitive performance at 2 months, maternal intelligence, and maternal responsiveness at 5 months relate to the expression of the three infant cognitive skills, but in different ways. Variation in infant information-processing abilities can be explained by specific child and maternal factors that are evident soon after birth.     

Household clutter and crowding constrain associations between maternal sensitivity and child theory of mind

Social interactions between parents and children are important for developing theory of mind, but these may be disrupted by aspects of the proximal home environment. The current study observed maternal sensitivity and its associations with child theory of mind and the housing environment (index by clutter and crowding) in a sample of mothers and their 3.5-year-old twins (N = 250 children). Maternal sensitivity and housing environment were measured from experimenter report and child theory of mind was measured through behavioural tasks. Results show that the association between maternal sensitivity and child theory of mind was moderated by the housing environment, where the positive associations between maternal sensitivity and child theory of mind were only observed at lower levels of clutter and crowding in the housing environment. Additional contextual variables and processes are discussed.     

Preterm birth enhances the contribution of mothers’ mind-mindedness to infants’ expressive language development: A longitudinal investigation

Maternal mind-mindedness has been shown to be a powerful predictor of many developmental outcomes and to buffer the impact of psychosocial risk conditions, but no study has investigated whether this parental feature might support child development in the presence of biological risk, such as preterm birth. The present study addresses this gap, by investigating whether early maternal mind-mindedness contributes to the growth of a child’s linguistic abilities in the following two years of life, and if the contribution of this maternal feature might be stronger in the presence of preterm birth. Forty mother–child dyads (twenty with a preterm infant) were followed longitudinally, with maternal mind-mindedness assessed at 14 months of age and child’s expressive linguistic abilities at 24 and 36 months through observational measures. Multilevel models showed that linguistic abilities increased from 24 to 36 months of age, but that this increase was stronger in full-term infants. Maternal mind-mindedness also contributed to this growth, playing a stronger role in preterm infants than in full-term infants. Altogether, these findings contribute more deeply to the understanding of language development in preterm infants and of the joint contribution made by biological risk and environmental factors; from a practical standpoint, they suggest the importance of addressing mother’s mind-mindedness in order to support child’s language development.     

Sustained attention development during the toddlerhood to preschool period: associations with toddlers' emotion regulation strategies and maternal behaviour

The current study examined the role of maternal behaviour and toddlers' emotion regulation strategies in the development of children's sustained attention abilities. Participants for this study included 447 children (232 girls) obtained from three different cohorts participating in a larger ongoing longitudinal study. When the children were 2 years of age, mothers brought their children to the laboratory and were videotaped during several tasks designed to elicit emotion regulation and mother–child interaction. Sustained attention was also measured at the same visit via a laboratory task and in a subsequent visit when children were 4.5 years of age. Results indicated that toddlers' use of help‐seeking emotion regulation strategies was positively related to sustained attention, while avoidance behaviours and maternal behaviour characterized by high levels of overcontrolling/intrusiveness were negatively related to sustained attention at age 2. Significant interactions emerged such that high levels of maternal warmth/responsiveness buffered the negative associations between low use of distraction and high use of self‐comforting emotion regulation strategies and sustained attention at age 2. Maternal behaviour characterized by high levels of warmth/responsiveness also predicted greater growth in sustained attention from age 2 to 4.5. These findings are discussed in terms of how maternal behaviours and children's use of active versus passive emotion regulation strategies relate to sustained attention abilities.

The impact of early maternal verbal scaffolding and child language abilities on later decoding and reading comprehension skills

This study examined, via structural equation modeling, early predictors of children's 8 year reading decoding and 10 year comprehension at later school age. Maternal verbal scaffolding indirectly influenced both decoding and comprehension, through its support of children's language abilities at 3 and 4 years of age. Additionally, there was a trend for a direct effect of 4 year child language on reading comprehension at 10 years. As maternal verbal scaffolding was assessed during every day routines, this suggests that rich language input in the broad social context of the home promotes language and, in turn, later reading skills. Given that maternal verbal scaffolding can be enhanced through interventions, these results have important educational implications.     

Impact of maternal adverse childhood experiences on child socioemotional function in rural Kenya: Mediating role of maternal mental health

Mothers in low‐ and middle‐income countries (LMIC) suffer heightened vulnerability for adverse childhood experiences (ACEs), which is exacerbated by the multitude of risk factors associated with poverty and may lead to increased risk of psychiatric disorder. The constellation of complex, co‐occurring biological, environmental, social, economic and psychological risk factors are in turn transmitted to her child, conferring vulnerability for adverse development. This study examines the association between maternal intra‐ and extra‐familial ACEs, maternal education and the mental health of her child, mediated by maternal mental health. Mother‐child dyads (n = 121) in Machakos, Kenya were examined cross‐sectionally using self‐report measures of ACEs, maternal mental health and child internalizing and externalizing mental health problems. The four models proposed to examine the relationship between intra‐ and extra‐familial maternal ACEs and child internalizing and externalizing problems demonstrated indirect pathways through maternal mental health. These effects were found to be conditional on levels of maternal education, which served as a protective factor at lower levels of maternal ACEs. These models demonstrate how the impact of ACEs persists across the lifespan resulting in a negative impact on maternal mental health and conferring further risk to subsequent generations. Elucidating the association between ACEs and subsequent intergenerational sequelae, especially in LMIC where risk is heightened, may improve targeted caregiver mental health programs for prevention and intervention.     

Relative effects of breastfeeding intention and practice on maternal responsiveness

Our objective was to examine the differential effects of antenatal breastfeeding intention (BI) and breastfeeding practice (BP) on maternal postnatal responsiveness. We conducted a secondary analysis of longitudinal data from a subsample of 962 mother–infant dyads from a U.K.-based birth cohort study the Avon Longitudinal Study of Parents and Children. Exposures were BI and BPs measured at 32 weeks of gestation and 18 months’ postpartum. The outcome was maternal responsiveness assessed at 12 months’ postpartum. We used logistic regression analyses unadjusted and adjusted for confounders. Intention to breastfeed was associated with increased odds of postnatal maternal responsiveness independent of BP, adjusted odds ratio (OR) = 2.34, 95% CI [1.42, 3.86]. There was no evidence that BP was an independent predictor of maternal responsiveness, OR = 0.93, 95% CI [0.55, 1.57]. Life-course epidemiology analyses demonstrated that maternal responsiveness is most positive when both BI and BP are present. This is the first population-based study to provide evidence that BI during pregnancy is more strongly associated with maternal postnatal responsiveness than is BP. Further research is needed to understand the determinants of BI in pregnancy and its relationships with maternal responsiveness.     

Does child verbal ability mediate the relationship between maternal sensitivity and later self‐regulation? A longitudinal study from infancy to 4 years

There is a need to further examine the mechanisms by which maternal sensitivity influences the development of child self‐regulation. This study investigated the role of maternal sensitivity when infants were 10 months old and child verbal ability at 18 months, in relation to various aspects of self‐regulation at 48 months, in a sample of 95 typically developing children (46.3% girls). In particular, the study examined, from a Vygotskian perspective, whether child verbal ability, as measured by receptive and expressive language, mediated the relationship between maternal sensitivity and hot and cool aspects of self‐regulation in the child. As hypothesized, maternal sensitivity predicted child verbal ability, as well as working memory, set shifting, and delay of gratification. Child receptive language predicted set shifting, inhibition, and delay of gratification. In addition, receptive language mediated the relationship between maternal sensitivity and inhibition only. Additive effects of maternal sensitivity and child receptive language in relation to set shifting were found, and a main effect of maternal sensitivity on child delay of gratification. The results add to the body of research suggesting that responsive parenting and child verbal ability are important for the development of self‐regulation, and suggest that different mechanisms may be at work for different aspects of self‐regulation.     

Early infant temperament shapes the nature of mother-infant bonding in the first postpartum year

ObjectiveThis study examined longitudinal relations between maternal bonding and infant temperament in the first nine months after birth.DesignOur sample consisted of 281 women, enrolled at five maternity hospitals, who completed questionnaires during the first week (T1), at six weeks (T2) and nine months postpartum (T3). Maternal bonding was assessed using the Mother-to-Infant Bonding Scale at T1 and T2 and the Postpartum Bonding Questionnaire at T3. Infant temperament was measured using the Infant Characteristics Questionnaire, completed by the mothers at T2 and T3.ResultsThe results of a path model showed a long-term effect flowing from the child to the mother, with infant temperament at T2 predicting maternal bonding at T3 over and above stability in bonding. At T3, bonding was linked more strongly to child temperament at T2 than to child temperament assessed concurrently at T3. Maternal bonding did predict infant temperament, but this was true only of bonding reported at T1 and infant temperament at T2, that is, not of bonding assessed at T2 and infant temperament at T3.ConclusionOur results indicate that maternal bonding in the first week postpartum may temporarily affect child temperament, but infant’s temperament several weeks after birth – rather than several months postpartum – plays a pervasive role in shaping the long-lasting nature of the mother-child relationship. Our findings thus seem to support the suggestion that the early postpartum weeks represent an important period in the development of maternal bonding.     

Moderating effects of maternal emotional availability on language and cognitive development in toddlers of mothers exposed to a natural disaster in pregnancy: The QF2011 Queensland Flood Study

BackgroundPrenatal maternal stress exposure has been linked to sub-optimal developmental outcomes in toddlers, while maternal emotional availability is associated with better cognitive and language abilities. It is less clear whether early care-giving relationships can moderate the impact of prenatal stress on child development. The current study investigates the impact of stress during pregnancy resulting from the Queensland Floods in 2011 on toddlers’ cognitive and language development, and examines how maternal emotional availability is associated with these outcomes.MethodsData were available from 131 families. Measures of prenatal stress (objective hardship, cognitive appraisal, and three measures of maternal subjective stress) were collected within one year of the 2011 Queensland floods. Maternal emotional availability was rated from video-taped mother-child play sessions at 16 months: sensitivity (e.g., affective connection, responsiveness to signals) and structuring (e.g., scaffolding, guidance, limit-setting). The toddlers’ cognitive and language development was assessed at 30 months. Interactions were tested to determine whether maternal emotional availability moderated the relationship between prenatal maternal stress and toddler cognitive and language functioning.ResultsPrenatal stress was not correlated with toddlers’ cognitive and language development at 30 months. Overall, the higher the maternal structuring and sensitivity, the better the toddlers’ cognitive outcomes. However, significant interactions showed that the effects of maternal structuring on toddler language abilities depended on the degree of prenatal maternal subjective stress: when maternal subjective stress was above fairly low levels, the greater the maternal structuring, the higher the child vocabulary level.ConclusionThe current study highlights the importance of maternal emotional availability, especially structuring, for cognitive and language development in young children. Findings suggest that toddlers exposed to higher levels of prenatal maternal stress in utero may benefit from high maternal structuring for their language development.     

What's mom got to do with it? Contributions of maternal executive function and caregiving to the development of executive function across early childhood

Executive functions (EFs; e.g. working memory, inhibitory control) are mediated by the prefrontal cortex and associated with optimal cognitive and socio‐emotional development. This study provides the first concurrent analysis of the relative contributions of maternal EF and caregiving to child EF. A group of children and their mothers (n = 62) completed age‐appropriate interaction (10, 24, 36 months) and EF tasks (child: 24, 36, and 48 months). Regression analyses revealed that by 36 months of age, maternal EF and negative caregiving behaviors accounted for unique variance in child EF, above and beyond maternal education and child verbal ability. These findings were confirmed when using an early child EF composite‐our most reliable measure of EF – and a similar pattern was found when controlling for stability in child EF. Furthermore, there was evidence that maternal EF had significant indirect effects on changes in child EF through maternal caregiving. At 24 months, EF was associated with maternal EF, but not negative caregiving behaviors. Taken together, these findings suggest that links between negative caregiving and child EF are increasingly manifested during early childhood. Although maternal EF and negative caregiving are related, they provide unique information about the development of child EF.

The influence of maternal optimality and infant temperament on parenting stress at 12 months among mothers with substance abuse and psychiatric problems

The present prospective longitudinal study aimed to investigate the long‐term impact of maternal optimality assessed during pregnancy on parenting stress at infant age 12 months. In this study the concept of optimality was utilized to investigate maternal variations regarding resources during pregnancy in relation to later parenting stress, among three different groups of mothers that were recruited from substance abuse treatment, psychiatric outpatient treatment and well‐baby clinics respectively. The influence of infant temperament on parenting stress was also examined. All mothers were interviewed during pregnancy. At 12 months, infant temperament (Colorado Childhood Temperament Inventory; Rowe & Plomin, 1977) and stress in the parent and child domain (Parenting Stress Index; Abidin, 1955) were assessed. Results demonstrated higher levels of parenting stress among mothers in the clinical groups, compared to the non‐clinical group. Furthermore, it was the maternal psychiatric optimality index in combination with child temperament characteristics (child emotionality) that contributed uniquely to stress in the parent domain, while stress in the child domain was significantly associated only with child temperament characteristics (both child emotionality and soothability). The association between maternal psychiatric optimality assessed in pregnancy, infant temperament and parenting stress when the infants were 12 months old, points to the importance of simultaneously addressing the mothers' own psychological distress, and to support positive mother–infant interactions. Each woman's individual optimality profile may be used to display needs of follow‐up in order to prevent enduring effects of non‐optimality on parenting stress.     

The Maternal (Non) Responsiveness Questionnaire: Initial Factor Structure and Validation

The purpose of this paper was to examine the reliability, stability, and convergent and predictive validity of the newly developed Maternal Responsiveness Questionnaire (MRQ). Participants were 224 first‐time mothers. Mothers completed the MRQ when their infants were 6 and 14 months old. Convergent validity was examined in relation to mother‐reported personality, depressive symptoms, and emotion socialization practices and observed maternal sensitivity. Predictive validity was examined in relation to mother‐reported child behaviour problems and social competence, infant attachment security assessed via the Strange Situation, and observed child dysregulation. Three MRQ factors emerged based on exploratory factor analysis and were confirmed via confirmatory factor analysis: responsiveness, non‐responsiveness, and delayed responsiveness. All three scales demonstrated good internal consistency reliability and significant stability from 6 months to 14 months. Consistent evidence emerged for convergent and predictive validity of the non‐responsiveness subscale, but not the other subscales. The potential utility of the non‐responsiveness subscale of the MRQ is discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Maternal Behavior and Children's Early Emotion Regulation Skills Differentially Predict Development of Children's Reactive Control and Later Effortful Control

The role of maternal behavior and children's early emotion regulation skills in the development of children's reactive control, specifically behavioral impulsivity, and later effortful control was examined in a sample of 435 children. HLM analyses indicated significant growth in reactive control across the toddlerhood to early childhood period. Emotion regulation at age-2 positively predicted initial levels of children's reactive control abilities while maternal overcontrol/intrusiveness predicted lower levels of reactive control growth. Maternal behaviors at age-2 predicted children's effortful control abilities at age-5.5. Emotion regulation did not predict effortful control abilities. Maternal behavior and children's early emotion regulation skills may differentially facilitate the development of reactive and effortful control abilities.     

Exploring the relationships between maternal and child metacognitions and child anxiety

Research has shown that anxiety may be transmitted through verbal information pathways, for example, when parents share their anxious cognitions with their child. Less is known about the influence of parental metacognitions, that is, beliefs regarding thoughts, on child anxiety. We explored the relations between metacognitions in mothers and their children and anxiety in the children. Our study included 111 non‐clinical children aged 8 to 12 years and their mothers. Children rated their metacognitions, worry and anxiety, and mothers rated their metacognitions. Results indicated agreement between maternal and child metacognitions. Maternal metacognitions were positively associated with children's anxiety symptoms and worry, and this relation was mediated by the children's metacognitions. Our results warrant further examination of the role of parental metacognitions in child anxiety.
