Most of this research has examined the trajectories of monolingual children. However, it has also been proposed that bilinguals, who are exposed to greater phonetic variability than monolinguals and must learn the rules of two languages, may remain perceptually open to non-native language sounds later into life than monolinguals. Using a visual habituation paradigm, the current study tests this question by comparing 15- to 18-month-old monolingual and bilingual children’s developmental trajectories for non-native phonetic consonant contrast discrimination. A novel approach to the integration of stimulus presentation software with eye-tracking software was validated for objective measurement of infant looking time. The results did not support the hypothesis of a protracted period of sensitivity to non-native phonetic contrasts in bilingual compared to monolingual infants. Implications for diversification of perceptual narrowing research and implementation of increasingly sensitive measures are discussed.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638324000389/pdfft?md5=c00ad3bef85ef1512c611b6fe529c288&pid=1-s2.0-S0163638324000389-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141083145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence about the link between booksharing and language development in diverse cultural and socioeconomic settings is currently limited, hindering the formulation of a broadly applicable framework to understand the favorable conditions for early vocabulary development. This study explores the relationship between booksharing and early receptive and expressive vocabulary in a sample of 183 mothers and their toddlers in Costa Rica, a context where reading is not a common practice and children have limited access to books. Mothers completed an interview about their booksharing practices and reported children’s receptive and expressive vocabulary. Results demonstrated a positive link between maternal booksharing and children’s expressive vocabulary. Child gender moderated the link between booksharing and receptive vocabulary, exhibiting a stronger association in girls than in boys. Mothers with lower education levels reported higher expressive vocabulary scores for their children than mothers with higher education levels. These findings underscore the significance of booksharing in the home literacy environment, even in cultural contexts with distinct reading practices. Moreover, they highlight the need to incorporate sociocultural factors into comprehensive accounts concerning the role of booksharing in early word learning.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141072908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-two papers that met the selection criteria were selected. The study identified four types of conceptual definitions for SR, each associated with different constructs or sets of constructs: executive functions, temperament, the integration of executive functions and temperament, and physiological homeostasis. These definitions were based on mainstream approaches to SR rather than being specific to the Latin American region. The study also found compatibility between the sample and some observed trends. On one hand, there was an underrepresentation of the Latin American population in high-impact publications on the subject. However, from 2010 to the present, there is evidence of growth in publications on SR in the analyzed sample. On the other hand, the sample also indicates a disparate representation of the countries of Latin America and the Caribbean in existing publications. Finally, concerning the adaptation to the cultural context of the research, a small number of studies addressed this variable in a specific and significant way.

Infants and parents received a group-based program using a standard early childhood curriculum. In addition, all families were randomly assigned to receive parent training in the form of either parent-mediated Joint Attention Symbolic Play Engagement and Regulation (JASPER) training or psychoeducation. Infants in both classrooms made substantial gains in social-communication, play, and cognition during a brief, 8-week period. All infants gained over an average of 10 points in DQ and increased in standardized measures of social-communication and play, with these gains maintaining at a 2-month follow-up visit. The classroom that also received JASPER increased in child initiated joint engagement and play level during dyadic interactions with their parents, while the classroom that received psychoeducation increased in joint attention during a standardized assessment delivered by an independent assessor. Infant familial risk for autism (older sibling with autism) also moderated the effect of treatment on child initiated joint engagement where infants in the JASPER classroom without familial risk made the most gains from baseline to exit of the program.

In the Dominican Republic, the prevalence of exclusive breastfeeding among infants aged 0–6 months remains low, and the lack of a surveillance system has made it challenging to measure the impact of breastfeeding on early childhood development (ECD). This study aims to address the effect of ever breastfeeding on ECD. We conducted secondary data analysis from the Dominican System for Measuring Early Childhood Development (SIMEDID), a screening tool adapted and validated to the Dominican context that measures four areas of development: gross-motor, fine-motor, language, and socioemotional development. The data from SIMEDID can be cross-analyzed with other datasets generated by the National Institute for Early Childhood Comprehensive Care (INAIPI) that include information about breastfeeding. The children were evaluated during the standardization study of SIMEDID. To determine the breastfeeding impact, we: 1) conducted an analysis of covariance using ECD scores as dependent variables and ever breastfed as the independent variable, with age and sex as covariates (previously confirmed with an analysis of variance indicating the relevance of age and sex at birth in ECD); 2) analyzed the relative risk (RR) of developmental delay by breastfeeding status. We studied a sample of 699 Dominican children aged 12–36 months who receive services at INAIPI (the government institution responsible for administering comprehensive early childhood services). The results show that ever breastfed children had higher scores in overall ECD than those who were not; higher scores in language and fine motor development primarily drove this effect. The never breastfed group had a greater risk of developmental delay in fine motor and socioemotional development. These findings underscore the importance of promoting and supporting breastfeeding to improve child neurodevelopmental outcomes. This is particularly relevant in low-resource settings, where mothers may need additional support. Moreover, the study’s results provide evidence of SIMEDID’s validation, which can help inform future research and evidence-based decision-making toward optimal ECD in similar contexts.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638324000298/pdfft?md5=fd32bb97c40718c56d0a5622a19d8396&pid=1-s2.0-S0163638324000298-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140559019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
