BACKGROUND: Adolescent motherhood is accompanied by a constellation of risk factors that translate into developmental risk for the off-spring. Socioeconomic risk that is associated with adolescent motherhood as well as maternal interactive behaviors may contribute to the impact of adolescent motherhood on children's developmental outcome. OBJECTIVE: Therefore, the aim of the current study was to investigate differences in children's cognitive development between children of adolescent and adult mothers in their first two years of life and to examine whether socioeconomic risk (e...

Recent empirical studies reporting sex differences in attachment relationships have prompted investigators to consider why and under what conditions such results might be observed. This study was designed to explore possibilities of identifying sex differences in the organization of attachment-relevant behavior during early childhood. Observations of 119 children (59 boys) with their mothers and (separately) with their fathers were completed and children were described using the AQS. Results indicated that girls and boys did not differ with respect to global attachment security but at more specific level analyses revealed differences between parents that reflected differences in the behaviors of girls vs...

This study identified the level of trunk control of healthy term infants aged from six to nine months. This cross-sectional study included fifty-five infants aged from six to nine months. The levels of trunk control was investigated by using the Segmental Assessment Trunk Control (SATCo). The infants remained seated on a wooden bench and a neutral pelvic position was maintained. The SATCo score was considered as dependent variable. The results showed that infants aged six and seven months presented levels of trunk control in the thoracic region while infants aged from eight to nine months presented full trunk control...

BACKGROUND: Exposure to HIV during pregnancy is a risks to development. Exposed child should have assessed its development since birth. Alberta Infant Motor Scale is a tool which assess gross motor skills, with easy application and low cost. Up to now, this scale had not proven its validity for the population exposed to HIV. It's necessary to compare its with a gold standard tool, Bayley scale, which assess gross and fine motor skills, has a high cost and longer application time required...

Infants' early visual preferences for faces, and their observational learning abilities, are well-established in the literature. The current study examines how infants' attention changes as they become increasingly familiar with a person and the actions that person is demonstrating. The looking patterns of 12- (n = 61) and 16-month-old infants (n = 29) were tracked while they watched videos of an adult presenting novel actions with four different objects three times. A face-to-action ratio in visual attention was calculated for each repetition and summarized as a mean across all videos...

There have been few previous attempts to assess the development of early markers of executive function in infants born preterm despite well-established deficits reported for older preterm children that have been closely linked to poorer academic functioning. The present study investigates early attention control development in healthy 12-month-old age-corrected pre-term infants who were born less than 30 weeks and compares their performance to full-term infants. Eye-tracking methodology was used to measure attention control...

Early screening of children at risk for language difficulties is challenging. This study aimed to analyze the specificity and sensitivity of two screening methods at 2;0 years of age. In addition, the matter of what kind of information the use of word combinations and parental concern provide for screening was analyzed. The subjects were 78 children. The screening methods used were the Finnish versions of the short-form version of the MacArthur Communicative Development Inventories (FinCDI-SF) and the Communication and Symbolic Behavior Scales, Developmental Profile, Infant-Toddler Checklist (FinCSBS)...

The main aim of the present study was to examine differences in behavioral problems in toddlers born very preterm in Brazil and Italy. The sample comprised 154 toddlers (18-24 months of age) born very preterm, including 76 toddlers from Brazil and 78 toddlers from Italy. The Child Behavior Checklist was used to assess behavioral problems. Specific sociodemographic factors (i.e., maternal age at childbirth and maternal education) and neonatal factors (i.e., gestational age, sex, and length of hospitalization) were tested as potential mediators of country-related differences in behavioral problems...

The Still-Face Paradigm (SFP) enables researchers to examine the quality of mother-infant interactions. In typical infants, a classic still-face effect (SFE) has been confirmed whereby infants demonstrate reduced positive affect (PA), reduced gaze (GA), and increased negative affect (NA). Recently, the SFP has been used to examine the effect of maternal depression upon infant behaviour. However, the nature and consistency of the behavioural responses of infants of depressed mothers during the SFP remains unclear...

Canonical babbling (CB) is critical in forming foundations for speech. Research has shown that the emergence of CB precedes first words, predicts language outcomes, and is delayed in infants with several communicative disorders. We seek a naturalistic portrayal of CB development, using all-day home recordings to evaluate the influences of age, language, and social circumstances on infant CB production. Thus we address the nature of very early language foundations and how they can be modulated. This is the first study to evaluate possible interactions of language and social circumstance in the development of babbling...

This study examined the array of associations among the emotional valence and the coherence of mothers' representations of their relationship with their toddlers, mothers' reported parenting stress, and toddlers' internalizing and externalizing behaviors. To evaluate maternal representations, 55 mothers were interviewed using the Five Minute Speech Sample procedure (FMSS; Magaña et al., 1986), which was coded for criticism and positive comments (Magaňa-Amato, 1993), as well as coherence (Sher-Censor & Yates, 2015)...

BACKGROUND: Few studies have examined the relation between anxiety disorders in the postpartum period and cognitive as well as language development in infancy. AIMS: This longitudinal study investigated whether anxiety disorder in the postpartum period is linked to infant development at twelve months. A closer look was also taken at a possible link between maternal interaction and infant development. STUDY DESIGN: Subjects were videotaped during a Face-to-Face-Still-Face interaction with their infant (M = 4...

BACKGROUND: In typical development, postural adjustments during reaching change in the second half of infancy, including increasing rates of direction-specific adjustments. These changes are absent or different in infants at risk of cerebral palsy (CP). To discover whether these changes are related to acquisition of independent walking, we studied postural adjustments during reaching in infants before and after they learned to walk. METHODS: Ten typically developing (TD) infants and 11 infants at very high risk (VHR) of CP were assessed before and after they learned to walk...

OBJECTIVE: Although predictors of the prevalence of behavioral problems in preterm-born children have been frequently studied, predictors of behavioral change in these children remain unknown. Therefore, in this study we explore predictors of short-term changes in problem behavior in preterm-born preschoolers, an age period characterized by rapid behavioral change. METHOD: Two- to 5-year-old children born with a gestational age <32 weeks and/or birth weight <1500 g were eligible, because of their high risk for behavioral problems...

We tested the hypothesis that an environment with fewer toys will lead to higher quality of play for toddlers. Each participant (n=36) engaged in supervised, individual free play sessions under two conditions: Four Toy and Sixteen Toy. With fewer toys, participants had fewer incidences of toy play, longer durations of toy play, and played with toys in a greater variety of ways (Z=-4.448, p<0.001, r=-0.524; Z=2.828, p=0.005, r=0.333; and Z=4.676, p<0.001, r=0.55, respectively). This suggests that when provided with fewer toys in the environment, toddlers engage in longer periods of play with a single toy, allowing better focus to explore and play more creatively...

Previous literature has demonstrated cultural differences in young children's use of communicative gestures, but the results were mixed depending on which gestures were measured and what age of children were involved. This study included variety of different types of gestures and examined whether children's use of communicative gestures varies by their cultural backgrounds and ages. 714 parents of children (6-36 months old) from U.S.A. English-, German-, and Taiwan Chinese- speaking countries completed the questionnaire on their children's use of each gesture described in the survey...

BACKGROUND: Efforts to understand the developmental pathways for disorganized attachment reflect the importance of disorganized attachment on the prediction of future psychopathology. The inconsistent findings on the prediction of disorganized attachment from the dopamine D4 receptor (DRD4) gene, birth weight, and maternal depression as well as the evidence supporting the contribution of early maternal care, suggest the importance of exploring a gene by environment model. METHODS: Our sample is from the Maternal Adversity, Vulnerability, and Neurodevelopment project; consisting of 655 mother-child dyads...
