The development and predictive relations of play and language across the second year.

The play and language development of 171 toddlers was examined at 14 and 18 months by observing their activities on the Symbolic Play Test and by assessing their language skills using the MacArthur Communicative Development Inventories (MCDI) and the Reynell Developmental Language Scales. Additionally, data from the Bayley Scales of Infant Development and the MCDI were obtained at 24 months, in order to investigate how play and language measures taken at 14 and 18 months predict children's development at the age of 2 years. The results showed that the vocabulary production and symbolic play of the 14-month-old toddlers made a unique contribution to their language and cognitive skills at the age of 2 years, while at 18 months only language variables made a similar contribution. Other-directed pretense discriminated between the children's subsequent language and cognitive skills best, whereas nonsymbolic play had no independent predictive contribution. Significant gender differences were found in the use of nonsymbolic and symbolic play acts already at 14 months. Gender did not, however, contribute to the prediction of the children's subsequent skills, whereas maternal education significantly added to the prediction of the 2-year-olds' maximum sentence length and that of their cognitive development.     

The predictive validity of nonverbal communicative skills in infants with perinatal hazards

This study investigated the predictive validity to 5 years of age of nonverbal communicative skills administered at 13 months. Subjects (N = 103) were Norwegian infants with birthweight below 1501 gms. The predictors included infant competence assessed by the Early Social-Communication Scales (ESCS). Cognitive competence at 2 years was measured by the Bayley Mental Development Scale, and at 3 and 5 years by the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). Language competence at 2 and 3 years was assessed by the Reynell Developmental Language Scales, and at 5 years by a verbal comprehension factor derived from the SB:FE. Partial correlations and multiple regression analyses suggest that the infants' initiation of communication was related to cognitive ability and language skills up to 5 years of age. In particular, joint attention was the most consistent predictor of the subsequent competencies. The Bayley cognitive index was overruled as a predictor when used in combination with initiation of joint attention.     

The Effect of Research with Teenage Mothers on the Development of Their Infants1

Mother-infant interaction of 14 teenage mothers and 12 women 20 years or older was observed and recorded in the laboratory or the home when the infants were 16, 20, 24, and 52 weeks of age. In order to assess the possible effect of the research intervention on the maternal behavior and on the infants' development, a control group of teenage mothers and their infants was seen only at the end of the study when the infant was 52 weeks old. At 12 months the Home Observation Measure of the Environment Inventory (HOME) was administered and infants were assessed with the Bayley Scales of Infant Development (motor and mental scales) and the Ainsworth Strange Situation procedure. On all measures the observation groups scored significantly higher than the control group. The significant aspects of the research intervention are discussed.     

Predicting preschool motor and cognitive performance in appropriate-for-gestational-age children born at ≤ 32 weeks gestation

Although many follow-up studies have been performed on preterm infants, little attention has been devoted to prediction of motor skills in the preschool or school years. We studied the relationship of performance on the Bayley Scales of Infant Development at a mean corrected age of 21 months to performance on the McCarthy Scales of Children's Abilities at a mean corrected age of 44.7 months for 43 appropriate-for-gestational-age (AGA) children born at ≤ 32 weeks gestation. Motor scores were stable over time with a significant correlation between the Bayley Psychomotor Developmental Index (PDI) and the McCarthy Motor subscale (r = 0.60; p = 0.0001). Scores of cognitive abilities also showed a significant correlation between the Bayley Mental Developmental Index (MDI) and the McCarthy General Cognitive Index (r = 0.42; p = 0.009). Small-for-gestational-age (SGA), very low-birthweight (≤ 1500 grams) children scored lower on the McCarthy General Cognitive Index (p = 0.01) and on the Motor subscale (p = 0.047) than the AGA children. We concluded that motor performance of AGA children born at ≤ 32 weeks gestation is stable from toddlerhood to preschool age. We suggest that SGA children be excluded from studies of motor performance of prematurely born children.     

Effects of maternal postpartum depression in a well‐resourced sample: Early concurrent and long‐term effects on infant cognitive,language, and motor development

This study examined early and long‐term effects of maternal postpartum depression on cognitive, language, and motor development in infants of clinically depressed mothers. Participants were 83 mothers and their full‐term born children from the urban region of Copenhagen, Denmark. Of this group, 28 mothers were diagnosed with postnatal depression three to four months postpartum in a diagnostic interview. Cognitive, language, and motor development was assessed with the Bayley Scales of Infant and Toddler Development third edition, when the infants were 4 and 13 months of age. We found that maternal postpartum depression was associated with poorer cognitive development at infant age four months, the effect size being large (Cohen's d = 0.8) and with similar effects for boys and girls. At 13 months of age infants of clinical mothers did not differ from infants of non‐clinical mothers. At this time most (79%) of the clinical mothers were no longer, or not again, depressed. These results may indicate that maternal depression can have an acute, concurrent effect on infant cognitive development as early as at four months postpartum. At the same time, in the absence of other risk factors, this effect may not be enduring. The main weaknesses of the study include the relatively small sample size and that depression scores were only available for 35 of the non‐clinical mothers at 13 months.     

Exploring the cognitive development of children born to adolescent mothers in South Africa

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10–19 years) and their first-born children (0–68 months). All adolescents completed questionnaires relating to themselves and their children, and standardized child cognitive assessments (Mullen Scales of Early Learning) were undertaken. Cognitive development scores of the sample were lower than USA reference population scores and relative performance compared to the reference population was found to decline with increasing child age. When compared to children born to adult mothers in the sub-Saharan African region, children born to adolescent mothers (human immunodeficiency virus [HIV] unexposed; n = 724) were found to have lower cognitive development scores. Findings identify critical periods of development where intervention may be required to bolster outcomes for children born to adolescent mothers.

Highlights

• An exploration of the cognitive development of children born to adolescent mothers within South Africa utilizing the Mullen Scales of Early Learning.
• Cognitive development scores of children born to adolescent mothers within South Africa were lower compared to USA norm reference data and declined with child age.
• Previous studies utilizing the Mullen Scales of Early Learning within sub-Saharan Africa were summarized, and comparisons were made with the current sample.
• Findings highlight a potential risk of developmental delay among children born to adolescent mothers compared to children of adult mothers in the sub-Saharan African region.

     

Maternal anxiety and depression and development of prematurely born infants in the first year of life

The purpose of this study was: (a) to assess and to compare anxiety and depression symptoms in mothers of preterm neonates during hospitalization in the Neonatal Intensive Care Unit, after discharge, and at the end of the infants' first year of life; and (b) to assess the child's development at 12 months of chronological corrected age (CCA). Thirty-six mothers, with no psychiatric antecedents assessed with the SCID-NP, were evaluated by STAI and BDI. The infants were assessed with Bayley-II Scales. There was a significant decrease in clinical symptoms of state-anxiety in mothers (p = .008), comparing the period during hospitalization and after discharge of the infants. Clinical symptoms of anxiety and depression were observed in 20% of the mothers at the end of the infants' first year of age. The majority of the infants exhibited normal development on Bayley-II at 12 months CCA; however, 25% of the infants displayed cognitive problems and 40% motor problems. The mothers' anxiety and depression symptoms decreased at the end of the first year of life of the pre-term infants and the children showed predominately normal development at this phase.     

The mediated learning experience (MLE) in a three generational perspective

Previous research has shown that mediated learning experience (MLE) strategies are important for the development of cognitive skills. Theoretically, grandparents have a significant role in the intergenerational transmission of MLE strategies. The purpose of this study is to investigate the resemblances and unique characteristics of mothers' and grandmothers' MLE strategies. A sample of 52 Israeli families composed of mother–child and maternal grandmother–child dyads were videotaped at home in two conditions: free play and structured (the same child was observed in each dyad). The interactions were analysed using the observation of mediated interaction (OMI). Higher levels of MLE strategies were found during free play than in the structured condition. Positive correlations between grandmothers' and mothers' MLE strategies were found under both conditions. However, grandmothers provided a higher level of MLE strategies for intentionality and reciprocity, meaning, and transcendence, but less mediation of regulation of behaviour than mothers. It is concluded that these differences may be the result of either differences in the perceived roles of mothers and grandmothers, or differences in the levels of experience of mothers and grandmothers.     

Predictions of developmental patterns during infancy: Assessments of children 0–1 years

The present study investigated how neonatal behavioural organization was related to later mental development during the first year of life. The study further investigated the relationship between early social affective behaviour and later mental development. A group of 40 infants was assessed five times during the infants' first year, at three and 14 days and at four, eight and 12 months. The Brazelton Neonatal Behavioural Assessment Scale (NBAS), the Duve method (a clinically based method for observation of social affective behaviour), and Griffiths' Mental Development Scales were used to assess the development of the infants. The results indicate that early predictive behavioural components can be identified. Neonatal state control capacity was related to motor development at both eight and 12 months. Social responsitivity at four months was related to hearing and speech at eight as well as at 12 months. The NBAS dimensions were good predictors of eight months performance, but were poor predictors of 12 months performance.     

Early maternal stimulation and the development of cognitive competence and attention of preterm infants

The aim of the study was to investigate the relationship between several dimensions of maternal interactive behaviours, and cognitive development and attention in preterm infants. Of special interest was the question of whether high levels of maternal stimulation and activity may have negative consequences for the development of preterm infants. Sixty-six preterm infants and their mothers were followed longitudinally and videotaped in interaction situations at home, at the infant age of 6, 9 and 12 months. Mothers behaviours were scored on involvement, sensitive responsiveness, non-intrusiveness and level of activity. Moreover, infant cognitive status was assessed at 6, 12 and 24 months of age, using the Bayley Scales of Infant Development. Infant ability in problem solving and attention were assessed in two problem solving tasks at 18 and 24 months of age. The results showed that infant cognitive status at 12 and 24 months was best predicted by maternal involvement and infant responsiveness. No significant relationships were found between maternal interactive behaviours and infant ability in problem solving and attention. More importantly, there was no indication that high levels of maternal stimulation or intrusiveness may have a negative impact on later cognitive development and attention in preterm infants. © 1998 John Wiley & Sons, Ltd.     

Cognitive modifiability as a function of mother–child mediated learning strategies,mothers' acceptance–rejection,and children's personality

This study investigated (a) the effects of mediated learning experience (MLE) in mother–child interactions on cognitive modifiability as measured by dynamic assessment, (b) the effects of mothers' acceptance–rejection towards their children and the children's personality on the mothers' MLE strategies, (c) the combined effects of the mothers' acceptance–rejection, children's personality, and MLE strategies on children's cognitive modifiability, and (d) the prediction of cognitive modifiability by MLE interactions in two distinct conditions: free-play and structured. Fifty-four mother–child dyads (26 boys and 28 girls) in grade 2 were videotaped interacting in two situations: free-play and structured. The interactions were analysed with observation of mediation instrument using five criteria: intentionality and reciprocity, transcendence, meaning, feelings of competence, and regulation of behaviour. The children were administered the parent acceptance–rejection questionnaire, the personality assessment questionnaire, and the children's inferential thinking modifiability test. A distal–proximal factors of cognitive modifiability model was used to explain causal paths among mothers' acceptance–rejection and children's personality (distal) on MLE (proximal), and of both on children's cognitive modifiability. A structural equation model analysis revealed that (a) all MLE criteria were predicted by the distal factors of mothers' acceptance–rejection and children's personality, (b) none of the mothers' attitudes or children's personality factors explained the children's cognitive factors, (c) MLE criteria of transcendence and regulation of behaviour explained the children's CITM-post-teaching score but not the CITM-pre-teaching score. The results are discussed in relation to Feuerstein's MLE theory and Tzuriel's previous results with preschool children. © 1998 John Wiley & Sons, Ltd.     

Sensorimotor development in cocaine-exposed infants

This study investigated the effects of prenatal cocaine exposure on infant sensorimotor development. One hundred and sixty-seven12-month-olds (74 cocaine-exposed and 93 unexposed) were assessed using the Bayley Scales of Infant Development (BSID). Ninety-seven had previously been evaluated on the Movement Assessment of Infants and the Test of Sensory Functions in Infants at age 4 months. On the BSID, the cocaine-exposed infants performed less well on the Mental portion and were more frequently rated as behaviorally suspect. Cocaine-exposed infants also performed less well at four months on the motor and sensory measures. Early motor performance predicted 12 month BSID mental, motor and behavioral outcomes. Cocaine exposure had an effect independent from confounders on general cognitive and specific motor and behavioral outcomes.     

The role of early fine and gross motor development on later motor and cognitive ability

The aim of this study was to determine whether information obtained from measures of motor performance taken from birth to 4 years of age predicted motor and cognitive performance of children once they reached school age. Participants included 33 children aged from 6 years to 11 years and 6 months who had been assessed at ages 4 months to 4 years using the ages and stages questionnaires (ASQ: [Squires, J. K., Potter, L., & Bricker, D. (1995). The ages and stages questionnaire users guide. Baltimore: Brookes]). These scores were used to obtain trajectory information consisting of the age of asymptote, maximum or minimum score, and the variance of ASQ scores. At school age, both motor and cognitive ability were assessed using the McCarron Assessment of Neuromuscular Development (MAND: [McCarron, L. (1997). McCarron assessment of neuromuscular development: Fine and gross motor abilities (revised ed.). Dallas, TX: Common Market Press.]), and the Wechsler Intelligence Scale for Children-Version IV (WISC-IV: [Wechsler, D. (2004). WISC-IV integrated technical and interpretive manual. San Antonio, Texas: Harcourt Assessment]). In contrast to previous research, results demonstrated that, although socio-economic status (SES) predicted fine motor performance and three of four cognitive domains at school age, gestational age was not a significant predictor of later development. This may have been due to the low-risk nature of the sample. After controlling for SES, fine motor trajectory information did not account for a significant proportion of the variance in school aged fine motor performance or cognitive performance. The ASQ gross motor trajectory set of predictors accounted for a significant proportion of the variance for cognitive performance once SES was controlled for. Further analysis showed a significant predictive relationship for gross motor trajectory information and the subtests of working memory and processing speed. These results provide evidence for detecting children at risk of developmental delays or disorders with a parent report questionnaire prior to school age. The findings also add to recent investigations into the relationship between early motor development and later cognitive function, and support the need for ongoing research into a potential etiological relationship.     

Predictive factors of manual dexterity and cognitive performance at 17 years: a 10-year longitudinal study in a rural area of France

Studies of predictive factors of manual dexterity in adolescents and young adults are lacking. The present longitudinal study reports the relationship between cognitive and behavioural assessments at age 7 years and the schooling, cognitive performance, and manual dexterity at age 17 years. The participants were 65 schoolchildren, 30 boys and 35 girls, from a rural area in France. Assessment at age 7 years included the McCarthy scales and questionnaires measuring the behavior of the child, completed by the mother, the teacher, and the assessing psychologist. Assessment at age 17 years included schooling situation (whether they were in high school or not), cognitive testing (WAIS-R, Trail Making, Verbal Fluency, Cancel H, Stroop, Memory Assessment Scales), and manual dexterity testing (dynamometer, Finger Tapping, Santa Ana Test, Purdue Pegboard). After controlling for effects of parental education and IQ, a negative teachers' rating of children's behaviour and abilities in first-grade (7 years) was correlated with early cessation of schooling, but also, unexpectedly, with higher scores for manual dexterity at 17 years. Manual dexterity was not related to cognitive performance at 17 years. It is suggested that the relationship between manual and cognitive performance varies during development. Although manual exploratory behaviour is an important correlate of early cognitive development, manual dexterity is probably not related to later academic performance.     

Infant temperament and performance on the Bayley Scales of Infant Development at 4, 8, and 12 months of age

Infants were assessed with the Rothbart Infant Behavior Questionnaire (an objective measure of infant temperament based on maternal reports) and the complete Bayley Scales of Infant Development (BSID) at 4, 8, and 12 months of age. Activity level was related to BSID performance at each age with babies who obtained higher scores rated as more active. Activity level was also related to the infants' behavior during the test administration at 8 and 12 months. A negative relation was found between smiling and laughter and the mental development index at 8 and 12 months. These data suggest that aspects of infant temperament as assessed by maternal report share a small amount of variance with BSID performance and the amount of shared variance increases with age.     

FATHER–CHILD INTERACTIONS AT 3 MONTHS AND 24 MONTHS: CONTRIBUTIONS TO CHILDREN'S COGNITIVE DEVELOPMENT AT 24 MONTHS

The quality of father–child interactions has become a focus of increasing research in the field of child development. We examined the potential contribution of father–child interactions at both 3 months and 24 months to children's cognitive development at 24 months. Observational measures of father–child interactions at 3 and 24 months were used to assess the quality of fathers’ parenting (n = 192). At 24 months, the Mental Developmental Index (MDI) of the Bayley Scales of Infant Development, Second Edition (N. Bayley, 1993 ) measured cognitive functioning. The association between interactions and cognitive development was examined using multiple linear regression analyses, adjusting for paternal age, education and depression, infant age, and maternal sensitivity. Children whose fathers displayed more withdrawn and depressive behaviors in father–infant interactions at 3 months scored lower on the MDI at 24 months. At 24 months, children whose fathers were more engaged and sensitive as well as those whose fathers were less controlling in their interactions scored higher on the MDI. These findings were independent of the effects of maternal sensitivity. Results indicate that father–child interactions, even from a very young age (i.e., 3 months) may influence children's cognitive development. They highlight the potential significance of interventions to promote positive parenting by fathers and policies that encourage fathers to spend more time with their young children.     

Read your baby: A follow-up intervention program for parents with NICU infants

An intervention model designed to provide education and support to parents of sick or preterm infants throughout their first year of life is described. The intervention focused on helping parents communicate more skillfully with their infant and encouraging parents to maximize their infant's participation in the family system. Seventeen medium-risk infants received intervention; another seventeen served as controls. Independent evaluations of all families at 12 months adjusted age revealed that intervention babies were significantly advanced on Bayley Scales of Infant Development and Mastery Motivation tasks and that their mothers viewed them as easier to care for and less irritable.     

Child,Parenting, and Situational Characteristics Associated with Toddlers' Prosocial Behaviour

The infant and toddler years are crucial for the development of prosocial behaviour, such as helping, sharing, comforting and cooperation. Recent evidence suggests that the correlates of different types of prosocial behaviour may differ. The current study investigated whether child, maternal parenting and situational characteristics were differentially associated with toddlers' cooperation and concern with a peer. The sample, drawn from the National Institute of Child Health and Human Development Study of Early Child Care, included the 612 children who participated in the 36‐month dyadic play session and their mothers. The results indicated that girls were more cooperative and expressed more concern than boys. Greater sustained attention to toys was associated with lower cooperation. Children were more cooperative with peers who engaged in more positive social interaction, and expressed more concern with peers that they had a close relationship with. Maternal sensitivity at 24 months was associated with greater cooperation when the peer engaged in more positive social behaviour. Finally, both maternal sensitivity and cognitive stimulation at 15 months indirectly influenced toddlers' cooperation through maternal sensitivity at 24 months, underscoring the predictive power of early parenting when children are rapidly developing the capacity to engage in prosocial behaviour. Overall, the results highlight some differences in the correlates of toddlers' cooperation and concern. Copyright © 2015 John Wiley & Sons, Ltd.     

Mothers' beliefs and children's long-term cognitive change: A developmental task interpretation

A longitudinal study was used to explore the following hypotheses concerning the relation between mothers' beliefs, their use of high distancing utterances and children's cognitive development: (1) beliefs moderate the impact of high-distancing utterances on children's development, and (2) beliefs reflect mothers' normative expectations that motivate themselves and their children to try to satisfy them. The participants consisted of 34 children and their mothers and teachers. Results for the motherchild dialogues indicated that the distancing–cognitive performance relationship was strongest for children whose mothers had the most positive beliefs. In addition, mothers' beliefs about a 4-year-old child were more strongly related to children's cognitive performance at ages 6 and 10 than to cognitive performance at age 4. Characteristics of both verbal parent–child and verbal teacher–child interactions at age 4 supported a developmental task interpretation of these findings.     

Maternal risk factors as predictors of developmental outcome in early childhood

This paper describes the rationale, procedures, and initial validation of an instrument which assesses distal environmental factors thought to negatively influence maternal caregiving ability. A sample of 36 lower class, single, black mothers (ranging in age from 14 to 19 years) of first born, full-term infants were included in an educational intervention program carried out during infants' first 12 months of life. The development of the maternal risk score (MRS) instrument was centered around four areas: maturity of mother, degree of planning of the mother, family support system and level of poverty. Initial, Year 1, Year 2, and Year 3 MRS scores were compared with infant development at one and two years as measured by the Bayley Scales, and at three years with the McCarthy Scales, using Pearson product-moment correlations. The initial MRS correlated negatively with the Bayley Mental Development Index (MDI) at Year 1 and also at Year 2 (N=−.38 and −.40 respectively, both significant at p<.05). The MRS for Year 1 showed significant negative correlations with the two Bayley MDIs: two and three year MRS scores were significantly related to three year McCarthy test scores. This screening instrument, which assesses qualitative aspects of the caretaking environment, appears to be a promising approach for identifying lower class mothers of infants who might be at risk for developmental disabilities.
