Infant-directed maternal speech is an important component of infants’ linguistic input. However, speech from other speakers and speech directed to others constitute a large amount of the linguistic environment. What are the properties of infant-directed speech that differentiate it from other components of infants’ speech environment? To what extent should these other aspects be considered as p...

Background: Infancy is the most important extra uterine period of brain development. And it requires environmental stimulation for expression of the developmental capabilities. Meanwhile, due to repeated environmental disparities foster care children are at risk for developmental delay. Aim: designing evidence based care package to improve motor skills of orphan living infants according to inte...

UNLABELLED Although maternal sensitivity has been shown to influence social-emotional development, the role of verbal stimulation on infant developmental outcomes has received less exploration. Recent research has focused on intentional behaviors within the context of a mother-infant interaction as a critical influence and as distinct from sensitivity. In this investigation 6377 mother-infant d...

Background: Occupational therapists focus on caregiver-infant reciprocity, which is influenced by a host of biopsychosocial factors and predictive developmental outcomes across domains. It important for early intervention professions to understand how different forms reciprocity may predict infant development in salient domains (i.e., language, mobility, co-occupation). Therefore, the purpose t...

Introduction: Sensitive mother-infant interactions are important predictors of long-term relationship, which is one factor having a positive impact on infant development. Considering preterm infants’ immaturity, and maternal sensitivity may not develop optimally. A systematic review showed that current evidence the effectiveness parent-infant interventions promoting parental in neonatal intensi...

Maternal childbearing attitudes and self-definition as related to maternal perceptions of infant temperament were investigated in a pilot study. Maternal attitudes, self-definition, and perceptions of infant temperament were determined through mothers' self-report. Results indicated that maternal attitudes-including self-confidence and feelings toward infants and children-were positively relate...

In neuroimaging, cortical surface atlases play a fundamental role for spatial normalization, analysis, visualization, and comparison of results across individuals and different studies. However, existing cortical surface atlases created for adults are not suitable for infant brains during the first two postnatal years, which is the most dynamic period of postnatal structural and functional deve...

Data relating to infant mortality in Salvador, Brazil, were analyzed in order to determine how infant mortality evolved in various parts of the city during the period 1980-1988. This analysis showed sharp drops in the numbers of infant deaths, proportional infant mortality (infant deaths as a percentage of total deaths), and the infant mortality coefficient (infant deaths per thousand live birt...

Infant research is often underpowered, undermining the robustness and replicability of our findings. Improving reliability infant studies offers a solution for increasing statistical power independent sample size. Here, we discuss two senses term in context research: reliable (large) effects measures. We examine circumstances under which are strongest measures most use synthetic datasets to ill...
