However, the manner in which verbal (i.e., mind-mindedness) and nonverbal (i.e., parental embodied mentalizing) parental mentalizing relate with one another on an individual level, and subsequently, how they contribute to parent-infant attachment, remains largely unexplored. Using a person-centered approach, this study aimed to identify verbal and nonverbal mentalizing profiles and their associations with infant attachment, as well as with parental factors and interactional context (e.g., exploration, transitions). Based on longitudinal studies from three countries (Canada, United Kingdom, and Israel), this study included 412 mother-infant dyads. Mind-mindedness and parental embodied mentalizing were assessed through two distinct observational procedures during free-play interactions at 6–8 months. Infant attachment was evaluated using the Strange Situation Procedure at 15–16 months. Latent profile analyses identified four parental mentalizing profiles based on verbal and nonverbal indicators: very low consistent, low consistent, high consistent, and inconsistent. The three consistent profiles reflected low or high levels across both verbal and nonverbal indicators, whereas the inconsistent profile was marked by inconsistency: these parents produced more non-attuned comments than other profiles but still demonstrated good embodied mentalizing and made appropriate mind-related comments. Results showed that the high consistent profile was associated with greater infant attachment security than the very low consistent, low consistent, or inconsistent profiles. This study suggests distinct parental mentalizing profiles based on verbal and nonverbal indicators, and their differential relations with later child attachment.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"80 ","pages":"Article 102113"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711418","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}

This narrative review outlines the empirical literature on infant and early childhood health among Indigenous families in the United States and Canada, within the context of intergenerational trauma and government policies that have contributed to social and health inequities across the lifespan. We illuminate a woven throughline toward traditional pathways for healing and amplify the critical value of transitioning from deficit-based to strength-based models. To address these inequities we outline theories, frameworks, and approaches to advance our understanding of Indigenous infant development and kinship systems. Specifically, historical trauma brings forward the need to support Indigenous infant development within ancestral contexts. Additionally, decolonial perspectives within the fields of infant development and child welfare are needed in recognition of the harm caused by Western frameworks and to highlight the strengths of Indigenous-led approaches. For example, the Indigenous connectedness framework identifies the significance of environmental, community, family, intergenerational, and spiritual connection for healthy development. Decolonized perspectives and Indigenous theories support the revitalization of Indigenous birth justice practices which uplift community-led efforts. Indigenous worldviews and applications regarding infant development and generational healing are highlighted.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"80 ","pages":"Article 102120"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144750840","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 Baby Toolbox is intended to serve as a “common currency” across developmental fields and provide an extension to the NIH Toolbox for Assessment of Neurological and Behavioral Function® (NIHTB), which is appropriate for individuals from 3 to 90 years of age. The Baby Toolbox was normed using a nationally representative sample of infants and toddlers aged 16 days to 48 months old from the US population (<em>N</em> = 2515; <em>n</em> = 2042 English, <em>n</em> = 473 Spanish).

After data collection, the demographic targets were updated to reflect the current figures. Cases were individually weighted to ensure representativeness. Unweighted and weighted demographics are reported herein. Scores were regressed on age in months (for ages where the tests or composites were appropriate) using generalized additive models for location, scale, and shape to obtain expected reference values and standard deviations across age. The Baby Toolbox norming study has been designed to minimize bias and maximize representativeness and precision of estimates.

In this study, we related multiple infant cognitive measures derived from eye-tracking data to individual differences in emotional and cognitive dimensions of maternal caregiving. Participants were 66 mothers and their infants (mean age: 8.0 months, SD=1.1). Mother-infant interactions (during a diaper change and joint book reading) were recorded and subsequently observed by independent raters to assess maternal caregiving quality. Infant eye-tracking data, collected during a visual learning task, were used to inform a Bayesian cognitive model and infer individual differences in attention, learning, processing speed, and curiosity. We found a U-shaped relation between infants’ attention and maternal caregiving. Infants with very low and very high attention scores received higher-quality caregiving from their mothers, while infants with intermediate scores received lower-quality caregiving. This may indicate that mothers adapt their caregiving behaviour to the attentional needs of their infants, providing higher-quality caregiving to infants who either struggle to engage (low attention scores) or disengage (high attention scores). Maternal caregiving quality was not associated with any other cognitive measure.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"80 ","pages":"Article 102075"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138306","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}

Yet beyond the effect of lack of physical contact, the importance of tactile contact to infants’ early development received scant research compared to that of vision or hearing. In the past 25 years that has changed. Touch has emerged as a major research area. In this article, we present five major lessons learned in the past quarter century from research on early infant-caregiver physical contact: 1) some touch is required, 2) touch is a form of communication, 3) touch is pleasurable, 4) touch supports stress regulation, and 5) interventions that extend touch support infant development.

The aim of this study was to evaluate neuromotor and sensory development in premature infants over an 18-month corrected age period and to analyze changes in developmental trajectories during this time. In this prospective longitudinal study, 176 premature infants (born before 37 weeks gestation) were assessed at 1, 4, 8, 12, and 18 months of corrected age using the Neurological, Sensory, Motor, Developmental Assessment (NSMDA). The NSMDA scores showed clear improvement over time, with the biggest gains seen between the first and last assessments. Many infants who started with severe difficulties made significant progress, with some reaching a normal developmental range by 18 months. Additionally, a large portion of infants who were initially developing typically continued to do so throughout the study. The study underscores the potential for significant neuromotor and sensory development in premature infants within the first 18 months of corrected age.

Past studies have demonstrated that even infants tend to expect agents with certain characteristics (e.g., a larger body size) to prevail in dyadic zero-sum conflicts. Building on literature suggesting that adults and children associate high status with competent rather than incompetent individuals, we conducted three preregistered experiments to test whether infants predict that a physically competent agent will prevail in conflicts with a physically incompetent agent. In Experiment 1, 14- to 15-month-old infants watched a “competent” agent who jumped over a barrier and moved across a stage, and an “incompetent” agent who failed to jump over the barrier and, as a result, could not move across the stage. Infants looked longer, indicating a violation of expectation, when the incompetent agent subsequently prevailed in obtaining an object compared to when the reverse outcome was presented. Infants’ responses in Experiments 2a and 2b, although not significantly different from those in Experiment 1, suggested that this expectation was not merely due to differences in the agents’ goal achievement outcomes or the heights they could jump over the barriers. These findings suggest that infants expect physically competent agents—those who can achieve goals through physical abilities—to prevail in conflicts with agents who lack such demonstrations. This implies that the psychological bias to attribute high social rank to competent individuals is rooted in early development.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"80 ","pages":"Article 102090"},"PeriodicalIF":1.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271767","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}
