Patterns of mutual sequential coordination constitute stress regulation competences and provide foundation for later socio-emotional development. Maternal affective touch has been postulated as an essential regulatory factor in early social exchange. In this study we aimed to better understand the interplay between maternal affective tactile behaviors and physiological synchrony between mother and child, with possible implications for early bonding processes. Fifteen mother-premature infant dyads were video-recorded during a free interaction and directly after a skin-interrupting medical procedure (vaccination or blood sampling) in the Neonatal Intensive Care Unit. The proportion of maternal affective touch was coded both in free and post-stress interactions. Parasympathetic response was assessed simultaneously in mothers and neonates in order to observe physiological synchrony in dyads. Finally, interactional misattunement during mothers' comforting actions and infant behavior after stress was evaluated as a potential indicator of risk in early bonding processes. Results indicated a positive association between the duration of maternal affective touch and adaptive autonomic synchrony patterns in dyads. Correlations were found between maternal affective touch both before and after stress-inducing procedure and several synchrony measures from free interaction phase (Spearman ρ = –0,57 do 0,72, p &lt; 0,05) Additionally, the study revealed a positive correlation between the level of interactional misattunement and the duration of maternal affective touch after stress (ρ = 0,47, p &lt; 0,05).

The present study examined monolingual and bilingual Norwegian-learning infants’ discrimination of two Cantonese tone contrasts at 5 and 10 months, ages corresponding to the onset and offset of perceptual attunement. Results showed that while monolingual infants were sensitive to the salient contrast, bilingual infants showed sensitivity to both contrasts at 10 months. In sum, infant age and bilingual language background affected discrimination. Pitch accent language experience or contrast salience may also play a role. The finding that early bilingual experience facilitated tone perception is of particular interest. It suggests that infant perception could be enhanced by a more complex linguistic environment on a broader level. As this was observed only at 10 months, cumulative exposure may be required for infants in a complex bilingual environment. Future studies should disambiguate explanations generated from the current finding, ranging from neurocognitive plasticity to perceptual salience, and from experience-dependent to independent possibilities.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"77 ","pages":"Article 102003"},"PeriodicalIF":1.9,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645277","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}

This is evident in their progressively diminishing attention to relevant objects (e.g., a dog) as mispronunciations increasingly deviate from the correct word form (such as /dog/ changing to /gog/, /kog/, or /sog/). Despite these sensitivities, uncertainties remain about their broad generalizability, especially regarding the differences between word onsets and codas, and between lexical segmental (consonants and vowels) and supra-segmental (e.g., lexical stress and tones) elements. The present study aimed to fill these gaps. Using the intermodal preferential paradigm, we conducted two experiments to evaluate toddlers’ responses to coda and lexical tone mispronunciations. Our results revealed a linear decline in toddlers' attention to familiar objects as mispronunciations became more severe, suggesting that by 19–20 months, infants' lexical representations encompass detailed phonetic information of both segmental and supra-segmental categories. Moreover, our results indicate that toddlers utilize these details in lexical processing. Such findings offer a more comprehensive understanding of the phonetic structures within toddlers' early lexical representations, sheding light on the mechanisms toddlers use in processing various word positions, across different acoustic dimensions, and in multiple languages.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"77 ","pages":"Article 101999"},"PeriodicalIF":1.9,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142549792","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}

Using a bioecological framework, a secondary analysis of data from the nationally representative Growing Up in Ireland(GUI) Study was conducted. The sample consisted of 9793 children, aged 36 months (50.7 % male and 49.3 % female). The study examined if the frequency of engagement in different play activities predicted scores on measures of internalising, externalising and prosocial behaviours using the Strengths and Difficulties Questionnaire. Findings indicated that informal play activities such as games, painting and drawing, and reading predicted socioemotional development scores, in comparison with activities such as letter or number games, even after parental and other family factors are accounted for. The results also indicated that parent-child relationship factors of warmth, hostility and closeness are particularly important for socioemotional development.

However, the effect of perceptual narrowing on the combined perception of face and language stimuli is not well understood. Therefore, to investigate the changes in the sensitivity of infants to matches and mismatches between faces and speech which might occur in the course of perceptual narrowing, we tested 3- and 9-month-old German infants using German faces and German spoken sentences which would be familiar to the infants, as well as completely unfamiliar Chinese faces and French spoken sentences. The infants were tested using an intermodal association paradigm, whereby each infant saw sequences of German or Chinese faces, interspersed with German or French spoken sentences. We analyzed the total looking time of infants in conditions where the faces and spoken sentences were congruent (either both familiar, or both unfamiliar), versus incongruent conditions where only the faces or only the sentences were familiar. We found that while the 9-month-olds looked for similar durations in congruent versus incongruent conditions, the 3-month-olds looked significantly longer during congruent conditions versus incongruent conditions, indicating a greater attentiveness to face-speech matches and mismatches prior to the onset of perceptual narrowing.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"77 ","pages":"Article 101997"},"PeriodicalIF":1.9,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328167","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}
