Recently, a study demonstrated that greater maternal redirection (but not acceptance) of infant bids for attention predicted lower distractibility and, in turn, better receptive language outcomes in infants. To learn more about the potential basis for these relations, the current study took an in-depth look at differences in mother-infant dyadic behaviors as a function of whether mothers responded to infant bids for attention by redirecting versus accepting bids. We examined differences in infant gaze, mother-infant dyadic gaze, maternal multimodality (combining gaze, touch, and vocalizing), and maternal response speed. When infants (N = 67) were 12 months of age, we coded mother-infant interactions for maternal responses (accepted, redirected, ignored) to infant bids for attention. Maternal responses were further coded for multimodal behaviors (unimodal, bimodal, and trimodal) and speed of responding. The focus of infant gaze and maternal gaze were also coded (toy, partner, other). Results indicate that mothers engaged in more attentionally salient behaviors (e.g., more multimodal behaviors) when redirecting than accepting infant bids for attention, and that infants responded to those redirections with more joint attention and more looking to toys. The current study builds upon prior work and illustrates a potential process through which maternal redirection of infant bids for attention may facilitate attention control and language.\u0000 </div>","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147615835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is difficult to identify specific visual strategies from average-level data. This pre-registered study uses growth curve analysis within trials to explore individual differences in monolingual and bilingual children's dynamic allocation of visual attention to static faces (“Face Pop-Out”) and dynamic mouths (“50 Faces”). Participants were from Greater London in two age groups: 7- to 18-month-olds (n = 131) collected at the Birkbeck Babylab, and 18- to 34-month-olds (n = 745) whose data was publicly available from the Developing Human Connectome Project. Results show that children's attentional trajectories for viewing faces and mouths are sensitive to age and early language environment. Specifically, young bilinguals showed stronger systematic disengagement than monolinguals from faces and mouths after initial orientation. Older bilinguals prioritized the mouth more than monolinguals, driven by a steeper increase in mouth-looking over stimulus time. Age-dependent shifts in attentional allocation over stimulus time were evident within both age groups, particularly in static face viewing. In infants, younger children showed earlier re-fixations to static faces than older children. In toddlers, attention to faces was more stable over stimulus time in older than younger children. Overall, results suggest that age and early exposure to two languages modulates the temporal structure of children's social attention from 7- to 34-months of age.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13005695/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147494345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their findings are not generalizable to majority-world contexts, where the majority of the world's population lives. The limited research in the latter contexts reveals the presence of differing child language socialization practices, not generalizable across Global South contexts, and that socio-economic status (SES) and geographic location (rural/urban) can affect these practices. This study examined the language input to 5-month-olds in a low-SES, Afrikaans-speaking community in South Africa. Half of the 10 participating households were urban-situated and half rural-situated. Each home had a 1-h video recording of household members interacting naturally with and around the infant; these recordings were transcribed and coded in ELAN. The amount of child-directed speech (CDS) and number of (a) different utterance types, and (b) instances of contingent speech were determined. CDS comprised 76% of all utterances. Although there were no significant differences between urban and rural households when all CDS was considered collectively, more questions were directed at rural than urban infants, and more instances of speaking on behalf of the child occurred in the case of rural infants: in each recording, caregivers used “typical” CDS features (higher pitch, repetition, etc.) to speak in the first person but on behalf of infants, an infrequently reported phenomenon in CDS research. The types and number of utterances and the amount of CDS used did not pattern as reported by scholars for other low-SES, majority-world communities.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12988819/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147460508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 focusing on maternal odor has shown that smelling the mother can influence face processing in general as well as emotion processing more specifically. However, it is unclear to what extent these effects are specific to maternal odor or can also be found for other familiar social odors. To address this question, we investigated the impact of the father's odor on emotional face processing in 7-month-old infants (age at appointment 1: 209 ± 6 days [mean ± SD], range: 199–225 days; age at appointment 2: 217 ± 6 days, range: 206–231 days; gender: 15 girls and 15 boys). We recorded the infant's EEG response to female and male happy and fearful faces while infants were exposed to either their father's odor or the odor of a different infant's father. Analysis of the frontocentral Nc amplitude revealed an enhanced response to fearful compared to happy male faces only when infants smelled their own father but not when they smelled an unfamiliar father. In contrast, emotion processing at the occipital N290 was not affected by the presence of paternal odor, suggesting an impact of social odor on attention allocation rather than structural face processing. Interestingly, all effects were specific to male faces, pointing to a gender-specific impact of social odor. Our findings therefore provide first evidence for an influence of the father's odor on face processing, specifically male faces, in infancy.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12982682/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147445465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains unclear which types of responses are most relevant to this process. Here, we examined the role of contingent vocal imitation, defined as the prompt repetition of an infant's vocalization by an interaction partner. To tease apart the contribution of contingent vocal imitation from other elements of social interactions, we developed a novel vocal contingency paradigm. First, we investigated whether 5- to 6-month-old infants could rapidly learn the contingency between their own vocalizing and a novel imitative response. Then, we examined whether infants tested this newly learned contingency when it was suddenly discontinued. Novel audio-visual imitative responses were delivered and manipulated by an artificial agent. Infants' vocalizations were recorded while they experienced the novel contingency (connect phase) and its discontinuation (disconnect phase). Time-course analyses indicated a significant linear increase in vocalization frequency over time in the connect phase, supporting the hypothesis that contingent vocal imitation enables rapid vocal contingency learning. Descriptively, data suggested a quadratic trend consistent with a vocal extinction burst during the disconnect phase. However, this trend did not reach statistical significance. Therefore, there was only partial support for the role of contingent vocal imitation in the emerging sense of agency (i.e., young infants quickly learned this contingency, but there was no evidence that they tested it upon discontinuation). Overall, our paradigm provided proof of concept that vocal contingency learning can be studied in the absence of a human interaction partner.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12971622/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147391582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined newborns' sensitivity to emotional prosody above and beyond linguistic prosody marking different sentence types (i.e., interrogatives, imperatives, and declaratives) and its relation to maternal postnatal depressive traits. Forty-three newborns were presented with interrogative, imperative, and declarative utterances spoken each with happy, neutral, and sad prosodies while their non-nutritive sucking (NNS) behavior was measured and maternal depressive traits were assessed. Results revealed inhibited NNS behavior in response to sad and neutral utterances compared to happy ones (ps < 0.05), suggesting early differential responsiveness to positive vocal affect, independent of the linguistic prosodic contours of the sentence type. Moreover, reduced responsiveness to non-positive prosodies was positively associated with maternal postnatal depressive traits, suggesting that variation in the early affective environment may shape newborns' auditory-emotional sensitivity. These findings highlight the interplay between biological predispositions and environmental influences in early emotional processing, emphasizing the role of early auditory experiences in shaping socio-emotional development.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 2","pages":"e70087"},"PeriodicalIF":2.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13104800/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147785851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
