This study examines the infant-father attachment in infants born preterm (<?1500?g at birth and/or?<?37 weeks gestation) in comparison to full-term infants. The infant-father attachment was assessed using the Strange Situation Procedure at a (corrected) age of 15 months. We found at least half of preterm and full-term infants (50.0% and…

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

Although observational instruments are considered to be the gold standard for measuring toddler childcare quality, large-scale studies often have to rely on interviews or questionnaires. However, it remains unclear whether such reports can serve as reliable indicators for childcare quality. The present study used the ITERS and FCCERS to examine…

Findings from previous cross-sectional studies showed that while toddlers around their first birthday imitate selectively, that is, they systematically omit some kinds of target action steps or they copy only the goal, but not the means of the modeled actions, older toddlers imitate more exactly. The aim of the present article is to provide…

Recent research has shown that infants are more likely to engage with in-group over out-group members. However, it is not known whether infants' learning is influenced by a model's group membership. This study investigated whether 14-month-olds ("N" = 66) selectively imitate and adopt the preferences of in-group versus out-group members.…

Based on the concept of educational quality of the home learning environment, stimulating and responsive family time is crucial for children's development. In turn, time use depends on the developmental stages in childhood. International studies indicate that family patterns of time use are associated with a family's resources (i.e. level of…

Detecting self-generated actions and imitating other-generated actions are important abilities in order to interact with others. The relationship between these domains was investigated in 6-8-month-old infants. In a contingency-preference task, infants observed their own legs on a real-time and a delayed video display. In an imitation task, the…

Sensitive responding to others' emotional body expressions is an essential social skill in humans. Using event-related brain potentials, it has recently been shown that the ability to discriminate between emotional body expressions develops between 4 and 8 months of age. However, it is not clear whether the perception of emotional body expressions…

We investigated the development of the other-race effect "ORE" in a longitudinal sample of 3-, 6-, and 9-month-old Caucasian infants. Previous research using cross-sectional samples has shown an unstable ORE at 3 months, an increase at 6 months and full development at 9 months. In Experiment 1, we tested whether 9-month-olds showed the…

In this article, Ajay Chaudry and Heather Sandstrom review research on child care and early education for children under age three. They describe the array of early care and education arrangements families use for infants and toddlers; how these patterns have changed in recent decades; and differences by family socioeconomic status, race, and…

Background: Very preterm (VP; gestational age <32 weeks) and very low birth weight (VLBW; <1500 grams) is related to attention problems in childhood and adulthood. The stability of these problems into adulthood is not known. Methods: The Bavarian Longitudinal Study is a prospective cohort study that followed 260 VP/VLBW and 229 term-born…

Three-month-old Cameroonian Nso farmer and German middle-class infants were compared regarding learning and retention in a computerized mobile task. Infants achieving a preset learning criterion during reinforcement were tested for immediate and long-term retention measured in terms of an increased response rate after reinforcement and after a…

This study examined longitudinal relations between early measures of prosocial action in infancy as well as cognitive and social-cognitive abilities, and the sharing behaviour of preschool children. The results reveal relations between delay-of-gratification at 24 months and inhibitory control at 30 months, and children's sharing at 5 years.…

A randomized control intervention study was conducted to evaluate the effects of the highly structured Heidelberg Parent-Based Language Intervention (HPLI). The outcomes of 43 children (n = 23 intervention, n = 20 control) who had been identified as late talkers during routine developmental check-ups carried out in pediatric practices at the age…

In this essay, it is argued that a general understanding of human development needs a unified framework based on evolutionary theorizing and cross-cultural and cultural anthropological approaches. An eco-social model of development has been proposed that defines cultural milieus as adaptations to specific socio-demographic contexts. Ontogenetic…
