We found that both estimates of morphological segmentation reliably predicted expressive vocabulary at 30 months.

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":null,"pages":null},"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}

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.

It has already been well established that perceptual narrowing improves the sensitivity of infants to frequently encountered stimuli such as same-race faces and their native language while reducing their sensitivity to other-race faces and non-native languages. 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":null,"pages":null},"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}

Nevertheless, infants around 12 months can regain their sensitivity to other-race faces. For instance, exposing them to a specific statistical distribution and employing the mechanisms of statistical learning is one way to enhance their discriminatory abilities towards other-race faces. Following this idea, we investigated if even older infants around 2.5 years can be sensitized to other-race faces. We trained the infants with a bimodal distribution of a morphed continuum of Asian female faces with faces closer to the endpoints presented most frequently. We assessed infants’ discrimination of Asian faces by measuring their looking times after the training phase. The 2.5-year-olds showed a difference in looking times after the training, indicating that the exposure to a bimodal frequency distribution led to a successful discrimination between Asian faces.
