It was investigated whether infants could anticipate the angle of the circle’s direction after the bounce and the circle’s displacement from the location of bounce. Seven bounce types were presented which differed in the angle of incidence. Three of the seven bounce types showed physically implausible bounces. Saccades that started before the infant could perceive the bounce and ended after the bounce were analyzed. Infants’ saccades matched the circle’s displacement with sufficient accuracy to conclude that they made predictive saccades. Only results from two bounce types where the circle’s speed was less than 12.5°/s allowed for the possibility that infants made reactive saccades. The infants’ anticipated angle was close to the angle of the circle’s direction after the bounce. When the circle was moving at 40°/s, the difference between the two aforementioned angles was less than 15°, but it increased as the circle became slower. The effect of age on the saccade targets and other object-tracking measures was small and mostly masked by a large estimation error. Estimates of the saccade amplitude, saccade frequency, and the gaze-circle displacement were similar to those observed for saccades made when no bounce occurred and they were also similar to those reported in previous studies of infant object tracking with similar trajectories but without a barrier.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"78 ","pages":"Article 102029"},"PeriodicalIF":1.9,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049291","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}

Less is known, however, about the longitudinal effects and mechanisms predicting behavioral outcomes through early bedtime routine and emotion regulation in school-age children from low-income families. Thus, the present study examined emotion regulation at age three as a potential mediator in the longitudinal links between early bedtime routine and behavioral outcomes among racially diverse school age children from low-income families. Participants include a subsample of families (n = 2977) participating in the Early Head Start Research and Evaluation Project (EHSRE). Structural equation modeling with bootstrapping techniques was used to examine the models. The early bedtime routine index was created from parents’ reports at 14, 24, and 36 months. Children’s emotion regulation was drawn from interviewer assessments at 36 months and problem behaviors were reported by mothers when the child was approximately at age 10. Results indicated that children with consistent early bedtime routine were better able to regulate their emotions at age three. Also, emotion regulation at age three mediated the associations between early bedtime routine at 14–36 months and internalizing and externalizing behaviors among fifth-grade children. Findings indicated that consistent early bedtime routine helps children to regulate their emerging emotions which in turn has long-term benefits on their emotional and behavioral outcomes. These findings have important implications for pediatricians, nurse practitioners, nurses, and early childhood educators who can provide education and resources to support families in establishing consistent bedtime routine for their young children.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"78 ","pages":"Article 102027"},"PeriodicalIF":1.9,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142967657","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}

To address these challenges, the Quick Interactive Language Screener for Toddlers (QUILS:TOD; for children 24- to 36-months of age) was developed as a quick, tablet-based language screener capable of assessing children’s vocabulary, syntax, and word learning skills.

Results revealed that performance on the QUILS:TOD was predictive of QUILS performance, highlighting the utility of the QUILS:TOD for identifying which children at age two would continue to lag behind their peers at age three.

Previous research shows that skin-to-skin contact after birth and frequent baby wearing in the first year predict secure attachment at 12-months. This relationship is thought to be mediated by the activation of infants' parasympathetic nervous system through caregiver touch. However, little is known about everyday touch behaviors and their impact on infants' real-time parasympathetic activity. Laboratory observations may not accurately represent real-world interactions, highlighting the need for ecologically valid studies. To address this, we examined everyday dyadic touch behaviors and their real-time effects on infant parasympathetic activation. We video recorded N = 28 infants (1–10 months old) and their mothers at home for behavioral analyses. All infants wore wireless ECG sensors (1024 Hz) during video recordings, and n = 21 infants had high-quality ECG data that could be used for Respiratory Sinus Arrhythmia analyses. We used a dynamic measure of RSA (updated every 200 ms) as an index for real-time parasympathetic activation. We found that dyads touch interactions at home involve short, though highly variable bouts of physical contact, that change with infant age. Younger infants spent more time remaining stationary during contact and receiving more soothing touch compared to older infants. Only soothing touch – i.e., rocking, patting, bouncing, or stroking– led to immediate, significant increases in parasympathetic activity (RSA), and this effect was driven by younger infants. This study provides new insights into the ecological patterns of touch in early development and the biobehavioral mechanisms promoting secure attachment.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"78 ","pages":"Article 102021"},"PeriodicalIF":1.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866819","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}

Further, VOTs in IDS approached ADS values with infants’ age. However, we found no relationship between parents’ VOTs and infants’ consonant production or babbling.
