However, many autistic children experience delays and challenges in both gesture and vocabulary skills, and studies also show mixed gesture-vocabulary associations; thus, it is unclear whether gestures in autistic children support emerging vocabulary skills. To address previous conflicting findings, the current conceptual replication study uses linear models with a large sample (<em>N</em> = 451<em>)</em> of 12- to 24-month-old English-raised infants to investigate whether gestures are associated with expressive and receptive vocabulary. Using the infant-sibling design, gesture-vocabulary associations and group moderation were investigated in three groups: infant-siblings of autistic children who later meet the criteria for autism themselves (HL-ASD, <em>n</em> = 73), infant-siblings who did not meet criteria for autism (HL-Neg, <em>n</em> = 238), and a control group without a family history of autism (LL-Neg, <em>n</em> = 140). Both LL-Neg and HL-ASD groups showed positive associations between 12-month gestures and 18-month receptive vocabulary; however, only the LL-Neg group showed a positive association between 12-month gestures and 18-month expressive vocabulary. For 12-month gestures and 24-month receptive and expressive vocabulary, the LL-Neg and HL-Neg groups showed positive association, whereas the HL-ASD group did not. Similarly, the LL-Neg and HL-Neg groups showed positive associations between 18-month gestures and 24-month vocabulary, but the HL-ASD did not. Overall, the LL-Neg group showed significant gesture-vocabulary associations across all tested models, while the HL-ASD only showed one significant positive association.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"79 ","pages":"Article 102058"},"PeriodicalIF":1.9,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143814927","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}

One potential mechanism explaining this intergenerational transmission of behavior is parental beliefs. This longitudinal study examined the association between mothers’ remembered emotion socialization, specifically their perceptions of how their own mothers responded to their childhood distress, and their sensitivity to their own infants’ distress at both 6 and 14 months and possible indirect effects via mothers’ beliefs about crying. Participants were 259 primiparous mothers (128 European American, 131 African American). The path analysis indicated that mothers who recalled their own mothers responding to their childhood distress in a non-supportive manner had more mother-oriented beliefs (i.e., crying is a nuisance to be suppressed for the comfort of the mother and others) which predicted lower maternal sensitivity to their children’s distress at 6 months and 14 months. Although there was a positive association between supportive emotion socialization and infant-oriented crying beliefs (i.e., crying as a meaningful signal that warrants a response) and a marginal but non-significant positive association between infant-oriented crying beliefs and maternal sensitivity to distress at 6 months, the indirect pathway was not statistically significant. Thus, identifying mothers who experienced non-supportive emotion socialization in childhood and providing preventative interventions to reduce their mother-oriented cry beliefs may promote more adaptive parenting in infancy.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"79 ","pages":"Article 102056"},"PeriodicalIF":1.9,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724750","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}

Utilizing a longitudinal design, data were collected from 114 mother-infant dyads, including healthy full-term infants and those born prematurely with diagnosed respiratory disease, one group with chronic respiratory disease (Bronchopulmonary Dysplasia) and the second group with acute respiratory disease (Respiratory Distress Syndrome). Observational data were collected at 1, 4, 8, and 12 months post-term age, focusing on parental behavior, infant variables, and dyadic interactions during feeding. Confirmatory factor analysis was employed to assess the congeneric structure of the PCERA across three domains: parental, infant, and dyadic. Results indicated support for the congeneric model in all domains, demonstrating that each factor measured a single common latent variable despite variations in item loadings and error terms. Reliability analysis using Cronbach alpha and McDonald’s omega coefficients revealed high internal consistency for all eight PCERA factors, indicative of robust measurement properties (Table 3). Further examination of factorial invariance across four time periods (1, 4, 8, and 12 months) demonstrated consistent measurement properties of the PCERA factors throughout the infant's first year of life. This finding suggests stability and reliability in measuring the underlying constructs of mother-infant feeding interaction over time. The study underscores the utility of the PCERA as an observational tool for assessing various dimensions of parent-child interaction during feeding. Findings support its application in diverse settings, including the study of infants with complex medical conditions, such as prematurity and respiratory disease. Additionally, the study highlights the importance of examining parent and infant characteristics as predictors of feeding interaction quality, aiming to identify dyads at risk of poorer interaction outcomes and inform clinical interventions.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"79 ","pages":"Article 102038"},"PeriodicalIF":1.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644351","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}

This study examines the associations between temperament and motor system organization across three distinct social interaction tasks at 6 and 12 months of age. To account for the role of the caregiver’s mental well-being, we also included maternal trait anxiety in our analysis. A longitudinal sample of 83 infants at 6 months and 59 infants at 12 months participated in three caregiver-infant tasks: book-sharing, playing with manipulative toys, and rattle-shaking. Infant limb movements were recorded using wearable accelerometers, and we applied Multidimensional Recurrence Quantification Analysis (MdRQA) to extract Entropy (reflecting motor system complexity) and Mean Line (reflecting motor system stability). Using mixed-effects models, we examined the predictive effects of task and temperament variables: Negative Affectivity (NEG), Positive Affectivity or Surgency (PAS), and Orienting and Regulatory Capacity (ORC). Our results suggest that Negative Affectivity measured at 6 months predicted increased motor system Entropy and Mean Line concurrently at 6 months as well as longitudinally at 12 months. Temperamental variables measured at 12 months of age did not predict infants’ motor systems’ complexity and stability at the same time point. At 12 months, task conditions modulated both Entropy and Mean Line, suggesting greater sensitivity to contextual differences later in infancy. Additionally, higher maternal trait anxiety (measured at 4 months) predicted decreased motor system Entropy and Mean Line at 12 months.

Research has consistently shown that CT-mediated touch enhances infant parasympathetic tone, yet no clear patterns of mutual co-regulation between parent and infant have been reported. Here, we replicated our previous study design to test the impact of three minutes of maternal stroking touch on mother-infant cardiorespiratory regulation, using no-touch pre- and post-stroking baselines. To control for potential confounds, we standardised the infant’s holding position, used active baselines (i.e., active group) instead of resting baselines (i.e., resting group) to account for maternal metabolic activity, and compared stroking with and without massaging oil in the active group. Electrocardiogram (ECG) and respiration were measured in 30 mother-infant dyads (active group) and 24 mother-infant dyads (resting group) (infants aged 5–14 weeks) to calculate RRI-intervals (RRI), respiration frequency (<em>f</em>R), and Respiratory Sinus Arrhythmia (RSA). Surprisingly, no significant changes in mother and infant cardiorespiratory measures were observed in the active contrary to the resting group and the use of massaging oil had no notable impact in the active group. We suggest that these lack of changes show that subtle experimental manipulations have an influence on maternal-infant co-regulation, emphasising the importance of using research designs that respect the individualised ecological environment of parent-infant interactions and the role of micro-processes and multisensory integration in shaping regulatory attachment dynamics.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"79 ","pages":"Article 102051"},"PeriodicalIF":1.9,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593093","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}
