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.

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.

This paper describes the domain conceptualization, measure selection, and psychometric evaluation of the Baby Toolbox Social-Emotional Functioning measures.

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.

Mothers with infants (n = 106, boys = 59) 6–12 months of age were recruited with the goal of examining the effect of parent-child interactions on infant CNS response in the context of repeated trials of the Still Face Paradigm (SFP; Haley &amp; Stansbury, 2003). First, latent growth models (LGM) were estimated to examine infant EEG asymmetry across five trials of the repeated SFP, considering parent-child interaction predictors and controlling for relevant covariates. Second, latent profile analysis (LPA) was conducted to examine groupings of frontal asymmetry trajectories over the course of the task. Overall, a reliable pattern of changes across SFP trials was not observed, however, significant inter-individual variability was noted. Latent profile analysis was thus undertaken, indicating appropriateness of a three-group solution. Because two of the groups demonstrating change were small, these were combined to form a reactive profile. Subsequent analyses demonstrated that infants who experienced more reciprocal play with their caregivers were less likely to display significant frontal asymmetry reactivity to SFP when controlling for infant age and sex, maternal age, and socioeconomic status. This work provides evidence for the utility of LPA in infant EEG research, as well support for the capability model of frontal asymmetry.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"80 ","pages":"Article 102111"},"PeriodicalIF":1.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144694878","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}
