Ratings were compared to standard qualitative ratings and across two ethnic groups. Active Direction represents the provision of structure to interactions in the form of corrective direction with clear and concise feedback that is assessed for supportiveness rather than simple content or tone. The 7-point rating item was examined in observations of African American (<em>n</em> = 172) and Hispanic American (<em>n</em> = 196) mother-child interactions collected at age 2.5 years in families from low-income households. Ratings were compared and associations to previously reported ratings of the interactions were examined. Active Direction was often observed among the African American mothers (81%) but rarely observed among the Hispanic mothers (16%), with a large effect size difference, supporting the hypothesis that Active Direction may represent a culturally specific approach to parenting for African American parents. Maternal behavior correlations of Active Direction with cognitive stimulation, intrusiveness, scaffolding, and calm authority and with child affiliative obedience and dyadic routines and rituals were significantly higher and detachment significantly lower in the African American compared to the Hispanic sample. The new measure of Active Direction, centered around culturally salient values and differences in both historical and lived experiences, addresses characteristics of parenting in African American families that are supportive of their children’s development and provides a fruitful direction for future research.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"76 ","pages":"Article 101955"},"PeriodicalIF":2.1,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140905754","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}

Caregiver-mediated interventions have gained in popularity as a method for delivering support to the child and family. The current study builds on current work by enrolling a comparatively large cohort of infants (ages 12–22 months of age) displaying early signs of autism into a randomized controlled intervention program. 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. This study highlights the promise of intervening at the earliest stages to promote positive outcomes for children and families.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"76 ","pages":"Article 101952"},"PeriodicalIF":2.1,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638324000316/pdfft?md5=a1f2552c4d0ef9de538d0222bd2e483a&pid=1-s2.0-S0163638324000316-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140806966","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}

We critically evaluate various measurement approaches including subjective maternal perception, ultrasound, Doppler ultrasound, wearable technology, magnetocardiograms, and magnetic resonance imaging, highlighting their strengths and weaknesses. We discuss the challenges of accurately capturing fetal movement, which is influenced by factors such as differences in recording times, gestational ages, sample sizes, environmental conditions, subjective perceptions, and characterization across studies. We also highlight the clinical implications of heterogeneity in fetal movement assessment for monitoring fetal behavior, predicting adverse outcomes, and improving maternal attachment to the fetus.

Moreover, the study investigated to which extent the emergence of social pointing differs cross-culturally. We assessed non-social index-finger use and social pointing in 647 infants aged 3- to 24 months from 4 different countries (China, Germany, Japan, and Türkiye). Non-social index-finger use and social pointing increased with infants’ age, such that social pointing became more dominant than non-social index-finger use with age. Whereas social pointing was reported across countries, its reported frequency differed between cultures with significantly greater social pointing frequency in infants from Türkiye, China, and Germany compared to Japanese infants. Our study supports theoretical proposals of the dominance of non-social index-finger use during early infancy with social pointing becoming more prominent as infants get older.

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":"75 ","pages":"Article 101950"},"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}

Although infants engage in such interactions from the third month after birth, the prospective link between speech input and maternal sensitivity in the first half year of life and later language development has been understudied. We hypothesized that social interactions embodying maternal sensitivity, IDS and CTs in the first 3 months of life, are significantly associated with later language development and tested this using a longitudinal design. Using a sample of 40 3-month-old infants, we assessed maternal sensitivity during a structured mother–infant one-on-one (1:1) interaction based on a well-validated scoring system (the Coding Interactive Behavior system). Language input (IDS, CT) was assessed during naturally occurring interactions at home using the Language ENvironment Analysis (LENA) system. Language outcome measures were obtained from 18 to 30 months of age using the MacArthur-Bates Communicative Development Inventory. Three novel findings emerged. First, maternal sensitivity at 3 months was significantly associated with infants’ productive language scores at 18, 21, 24, 27, and 30 months of age. Second, LENA-recorded IDS during mother–infant 1:1 interaction in the home environment at 3 months of age was positively correlated with productive language scores at 24, 27, and 30 months of age. Third, mother–infant CTs during 1:1 interaction was significantly associated with infants’ productive language scores at 27 and 30 months of age.
