The current study examined parent and infant gaze, touching, pointing, and reaching to referents for a wide range of nouns, verbs, adjectives, and other early-learned words during 59 one-hour head-camera recordings sampled from one English-learning infants’ life between 6 and 12 months of age. We found substantial variability across individual words for all cues. Some variability was explained by referent concreteness and the grammatical category of the label. The parent’s touching of labeled referents increased across months, suggesting that parent-infant-referent interactions may change with development. Future studies should investigate the trajectories of specific types of words and contexts, rather than attempting to discover possibly non-existent universal trajectories of parent and infant referent-oriented behaviors.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638323001030/pdfft?md5=5dd429b341eda33a5beec36d8271918c&pid=1-s2.0-S0163638323001030-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138483889","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}

Previous research has investigated infants’ pointing with a variety of paradigms ranging from parent reports to field observations to experimental settings, suggesting that lab-based semi-natural interactional settings seem especially suited to elicit and measure infant pointing. With the Covid-pandemic the need for a comparable online tool became evident enabling also efficient, low-cost, large-scale, diverse data collection. The current study introduces a remote online paradigm, based on the established live ‘decorated-room’ paradigm. In Experiment 1, 12-months old infants and their caregivers (N = 24) looked at digitally presented stimuli together while being recorded with their webcam. We coded pointing gestures of infants and caregivers as well as caregivers’ responses to infants’ pointing. In Experiment 2 (N = 47), we optimized stimuli and investigated influences of stimulus characteristics. We systematically varied the style of depiction, stimulus complexity, motion, and facial stimuli. Main findings were that infants and caregivers pointed spontaneously, with mean behaviors ranging within the benchmarks of previously reported findings of the live decorated-room paradigm. Further, the social setting was preserved as revealed by significant relations between parents’ responsive points and infants’ pointing frequency. Analyses of stimuli characteristics revealed that infants pointed more to stimuli depicting faces than to other stimuli. The new remote online paradigm proves a useful addition to established paradigms. It offers novel opportunities for simplified assessments, large-scale sampling, and worldwide, diversified data collection.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138437856","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}

The sample consists of 236 Palestinian mothers from Gaza Strip singing to their six-month-olds a song by their own choice.

Mothers reported about their infants’ sensorimotor, language-vocalization, and socioemotional skills at six months, and psychologists tested these skills by Bayley Scales for Infant Development at 18 months. Results show that maternal IDSi characterized by wide pitch variability and rich and high vocal amplitude and vibration were associated with infants’ optimal sensorimotor, language vocalization, and socioemotional skills at six months, and rich and high vocal amplitude and vibration predicted these optimal developmental skills also at 18 months. High resonance and rhythmicity formants were associated with optimal language and vocalization skills at six months. To conclude, the IDSi is considered important in enhancing newborn and risk infants’ wellbeing, and the current findings argue that favorable acoustic singing qualities are crucial for optimal multidomain development across infancy.</p></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0163638323001005/pdfft?md5=8ba2488e03e838fdcbd82f3c4d01737b&pid=1-s2.0-S0163638323001005-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138296864","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}
