Therefore, understanding the factors involved in their early development is of paramount importance. The present longitudinal study aimed to obtain deeper insight into the role of fathers' and mothers' mind-mindedness in toddlers' EF. The sample included 131 families visited at home when children were aged around 6 (T1) and 19 (T2) months. At T1, both parents' mind-mindedness was rated, based on a 10-min parent-infant free play period, using a widely recognized and validated coding system capturing the number of appropriate and non-attuned comments on the child's mental states (emotions, thoughts, needs, and desires). At T2, child EF were measured with three behavioral tasks targeting inhibitory control, cognitive flexibility, and working memory. Regressions revealed that mothers' non-attuned comments were negatively and prospectively associated with all components of toddlers' EF, whereas mothers' appropriate comments were positively and prospectively associated with cognitive flexibility. Fathers' mind-mindedness was not associated with any EF components. The findings highlight the importance of maternal mind-mindedness in infancy for child EF during toddlerhood. This study provides novel insights into how maternal appropriate and non-attuned comments on children's mental states are distinctly related to child EF early in life.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 3","pages":"e70086"},"PeriodicalIF":2.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844580","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}

One reason for this is that we still have not agreed how to define, operationalize, and measure joint attention. The goal of this study is to examine the impact of applying two different joint attention operationalization schemes-reflecting distinct theoretical perspectives-to the same dataset of video-recordings of semi-naturalistic toy-play interactions between 12-month-old children and their caregivers (N = 39). We identified joint attention around relevant naming events to determine how these choices affect interpretations of the role of joint attention in vocabulary acquisition. We compared a gaze-based coding scheme, consistent with associative accounts of joint attention, with a socially coordinated joint attention coding scheme, based on social-pragmatic theories that require, in addition to gaze overlap, evidence of shared awareness. We then extracted two measures from each scheme: average joint attention event duration and the temporal overlap between joint attention events and naming events (JA overlap). We found that while measures of joint attention were predictive of later expressive vocabulary above and beyond language-based measures in both coding schemes, model comparison based on AIC/BIC indicated that joint attention defined as coordinated JA was preferred over joint attention defined as gaze overlap. Furthermore, the best fitting model predicting later vocabulary favored predictors based on the coordinated JA scheme. Our results suggest that a social operationalization of joint attention leads to better predictors of later vocabulary size than a gaze-based operationalization of joint attention. In addition, the current study emphasizes the critical role of methodological choices in understanding how and why joint attention is associated with vocabulary size.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 3","pages":"e70088"},"PeriodicalIF":2.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147864755","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}

This exploratory cross-sectional descriptive-correlational study examined associations between caregiver-reported caregiving practices and early socio-cognitive indicators in 26 children (9-36 months; M = 19.27, SD = 7.63) and their caregivers in San Basilio de Palenque, a culturally distinctive Afro-Colombian community. Caregiving practices were assessed using the Care Practices Scale, which captures the reported frequency and consistency of everyday routines and was interpreted within a nurturing care framework rather than as a direct measure of caregiving quality. Children's early socio-cognitive indicators were assessed with the Early Socio-Cognitive Development Checklist. Associations were examined using age- and sex-adjusted partial Pearson correlations, with Benjamini-Hochberg false discovery rate control applied to a pre-specified family of primary indicators. Caregivers reported high emotional warmth and frequent engagement in structured routines despite socioeconomic adversity. Several age- and sex-adjusted associations reached conventional significance (two-tailed p < 0.05), but none remained statistically significant after false discovery rate control (q = 0.05). Nominal patterns (prior to correction) clustered around joint-attention-related behaviors and receptive language and tended to co-occur with routine-based practices (e.g., hygiene) and relational guidance, suggesting culturally plausible hypotheses about how nurturing care may be scaffolded through everyday, interactionally dense routines. Findings are exploratory and should be interpreted cautiously. Overall, this study underscores the need for larger, multimethod, longitudinal research to test culturally grounded pathways of nurturing care in underrepresented Afrodescendant rural caregiving ecologies.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 3","pages":"e70090"},"PeriodicalIF":2.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147864682","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}

Parents' responsive linguistic input reduces uncertainty in label-referent associations and provides information at moments of infants' increased attention and receptiveness. While infants frequently lead the dyads' focus of attention, parent speech has been shown to scaffold infants' attention toward fixated objects. So far, however, little is known about the qualitative characteristics of parent speech during such interactions, and their effects on infants' attention. Here, we analyzed the role of the content and communicative intent of caregivers' speech to their 18-month-old infants (N = 31) during free play when infants or parents led an interaction, and when parent speech co-occurred with infants' sustained attention. Interactions were most likely to be infant-led, both temporally and topically, and parents' topically aligned, but not misaligned speech was associated with infants' sustained attention. Qualitative analysis of speech types revealed mostly object-focused speech in interactions with familiar objects, but a broader range of speech types in interactions with novel objects. We explain this pattern by suggesting that speech in interactions with familiar objects is structured by shared experience, whereas the lack of common ground with novel objects potentially induces parents to use more varied speech to engage their infants.","PeriodicalId":47895,"journal":{"name":"Infancy","volume":"31 3","pages":"e70089"},"PeriodicalIF":2.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13139530/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844552","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}

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.

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.

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}
