Infant and Child Development最新文献

It is known that infant-directed speech (IDS) plays a key role in language development. Previous research, however, has also identified significant variability across societies in terms of how often IDS occurs. For example, some studies report very little IDS in non-western, small-scale societies – including children growing up in small-scale societies in Tanna, Vanuatu. This is surprising given that IDS is widely assumed as a common feature of human caregiving based on research conducted in urbanised populations which are more well-studied. Here, we propose that IDS is only one of a suite of important caregiving behaviours that are produced during interactions with infants, which may vary by culture, perhaps being replaced by other, non-verbal infant-directed behaviours (IDB). We will examine previously collected data consisting of 94 semi-structured 10-min video observations of caregivers and their 18–24 month-old children in rural Tanna, Vanuatu and urban Vancouver, Canada to identify and compare the proportion of time caregivers spend engaging in IDS and IDB during these interactions, both within and between societies. We define IDS as caregiver speech or vocalisations during the interaction with the infant, and we define IDB as non-verbal behaviours that are produced with the infant during the interaction. This study aims to take a step towards a more generalised understanding of language development in children, moving beyond the urban and western societies in which our understanding of development is currently based, and the predicted results will aid in recognising different developmental pathways within multi-cultural communities.

The purpose of the current study was to qualitatively explore the home mathematical environment across two regions in two different countries (i.e., Cuba and Mexico), replicating a qualitative study previously conducted in Northern Ireland (NI), United Kingdom (Cahoon et al., 2017). Semi-structured interviews with parents/caregivers of children (3- to 5-year-olds) in both Mexico (n = 13) and Cuba (n = 40) were completed to investigate their views, experiences and attitudes towards the home mathematical environment. Thematic analysis was used to explore themes relevant to the home mathematical environment. Three consistent themes were found in the Mexican and Cuban data: Numeracy Environment Structure, Expectations and Attitudes and Views of Technology. Two unique themes were found in the Mexico data: Interactions Related to Reading or Mathematics, and Child's Attitudes in Relation to Mathematics. One unique theme was found in the Cuban interviews: Interactions for Learning. Although diverse themes were identified, consistencies were also observed. This suggests that some home numeracy practices may be universal in nature. This research increases the understanding of human development in context.

Interactions with primary caregivers shape children's expectations of interactions with others, but the mechanism is not clear yet. We included Han Chinese children aged 5–6 (N = 121, 61 boys) from a city in East China and tested their support-giving expectations of mothers, fathers and unfamiliar others after observing mother–child interactions with different levels of maternal responsiveness. Across two studies, we found that children's support-giving behaviour and willingness expectations decreased significantly in the unresponsive condition for mothers and fathers but not for unfamiliar others; while these expectations did not change significantly for all partners in the responsive condition. The results suggest that relationship type between children and interaction partners moderates the effects of maternal responsiveness on children's expectations of partners' support-giving. They shed light on how young children understand and represent interpersonal interactions.

The purpose of this study was to examine how the members of children's peer groups resemble each other in terms of behavioural and emotional strengths, academic achievement and behaviour at school. The participants were 739 9- to 10-year-old children (354 boys, 385 girls) from 30 Finnish elementary schools. 431 children (241 girls, 190 boys) were part of peer groups. Less than 5% of participants were other than Finnish origin. The children self-assessed their behavioural and emotional strengths, and teachers evaluated the children's academic achievement and behaviour at school. Children also filled the sociometric questionnaire and sociograms were drawn to identify peer groups. Standardized beta values of regression analyses were used as indicators of effect sizes. The results showed that when observed as a strength, children's school functioning was positively linked to both academic achievement and behaviour at school. The intraclass correlations (ICC) revealed that members of peer groups resembled each other in terms of behavioural strengths, and behaviour at school, but not in academic achievement. The gender composition of peer groups explained the variance in behaviour at school between peer groups. The results of this study highlight the importance to consider children's peer group also when implementing behavioural interventions.

The home numeracy environment is an essential construct that helps explain children's numeracy skills. However, this field has been developed mostly focusing on monolingual English-speaking families, and cultural differences that contextualize the home environment have not been considered. This study describes the home numeracy environment of Latine families by (1) identifying the more and less common numeracy activities in the home of Latine families; (2) exploring differences, such as family members involved in the activities and generation in the United States; and (3) examining the association between activities and math anxiety and beliefs. Participants were 341 caregiver-child dyads (M age = 2.9 years, SD = 0.7 months). We found that the less common numeracy activities in the home of Latine families are items commonly used in the literature to measure numeracy home environment. In addition, the role of family members varies across generations. This study provides a foundation for understanding the home numeracy environment of Latine families.

In response to the COVID-19 pandemic shut-down of in-person research laboratories, remote data collection became mainstream in developmental psychology research. The aim of this study was to test the feasibility of two remote data collection methods for studying sleep and motor development in infancy and the relationship between the two. We asked 1371 parents of infants aged 4–17 months who used the Nanit baby monitor to take the online Survey of Well-being of Young Children (SWYC) about their infants' motor experience. Nanit uses auto-videosomnography and computer vision algorithms to calculate and report summary statistics of infants' sleep. Nanit replicated all expected developmental trends in sleep, while the SWYC only replicated some, appearing to underestimate infants at the transition between motor milestones. However, we replicated some well-established findings regarding the relationship between sleep and motor development using both measures, suggesting that both Nanit and the SWYC can feasibly be used for remote data collection, especially if some modifications were made to how researchers explained using the SWYC to caregivers. Researchers should consider alternatives to traditional research methods not only when in-person participation is difficult or impossible, but also when large samples are needed and/or simple measurement tools are sufficient.
