Newborns seem to have communicative expectations and behave as if they predict others’ goal-directed actions. Despite these discoveries, I review key barriers to progress in newborn developmental science. First, newborn social behavior research has almost exclusively focused on “average” development—based primarily on White, wealthy, English-speaking, Western, populations—treating interindividual differences as noise rather than meaningful, variability. Focusing almost exclusively on averages, especially with small sample sizes, ignores interindividual differences and hinders discoveries. Second, there are few studies of newborn sociality beyond the first postnatal week. In part, this gap in our understanding may be due to, and a consequence of, the mischaracterizations of newborns’ behaviors as passive, limited, disorganized, and low-level reflexes that are subcortically driven. Finally, researchers often assume that newborns’ behaviors are largely independent of experience. To the contrary, newborns’ need for nearly continuous social contact provides them with rich social learning opportunities, which have been shown to have lasting impacts on their development. Given the uniqueness and plasticity of this period, and their high vulnerability, developmental scientists are doing newborns a disservice by neglecting to characterize their social repertoires within and across diverse populations. Awareness of newborns’ social capacities will facilitate a more objective, accurate view of their social potential.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"81 ","pages":"Article 102149"},"PeriodicalIF":2.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092804","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}

Longitudinal neuroimaging, in particular, offers a powerful means of capturing within-person changes in infant brain development over time, rather than relying solely on age-based normative comparisons. Yet despite this progress, longitudinal infant neuroimaging studies, especially in Majority World contexts, remain the exception rather than the norm. As a result, opportunities to intervene during the first 1000 days, a crucial window for neurodevelopment, are often missed. Building on foundational work in Jamaica and Romania, recent studies in The Gambia, India, Brazil, South Africa and Bangladesh have begun to establish scalable, longitudinal metrics of neurodevelopmental change that can be implemented across diverse study sites. These approaches hold promise not only for integration into large, representative cohort studies, but potentially into standard healthcare practice, laying the groundwork for identifying infants who may benefit most from early intervention, particularly given that many neuroimaging biomarkers emerge before 12 months of age. There have also been promising advances in interventions targeting both psychosocial and biological sources of early adversity to improve neurodevelopmental outcomes for at-risk infants.

The current study aims to 1) explore differences in infant affect and regulatory behaviors across two commonly implemented infant stress-induction paradigms and 2) evaluate the differential effects of depression and anxiety on infant regulatory behaviors. Six-month-old infants and their mothers (N = 126) completed two tasks remotely in the home: the Arm Restraint task and the Still-Face Paradigm. Maternal depression and anxiety symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) subscales. Within-person results indicated no significant associations among infant regulatory behaviors nor infant reactivity across the two paradigms. Additionally, no significant associations were found between maternal mental health and infant regulatory behaviors during the Still-Face Paradigm. However, higher EPDS composite scores were associated with fewer infant avoidance behaviors during the Arm Restraint task, and this result was driven by items on the anxiety subscale. These findings suggest that infant regulatory behaviors may differ depending on task used and may also be influenced by subclinical levels of maternal anxiety, but not maternal depression.</div></div>","PeriodicalId":48222,"journal":{"name":"Infant Behavior & Development","volume":"81 ","pages":"Article 102151"},"PeriodicalIF":2.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096415","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}

However, our understanding of infant attention has significantly evolved over the past 25 years, shaped by both theoretical advancements and new technological and methodological tools. Researchers now understand that attention development reflects multiple interacting systems that have cascading effects across time. The availability of infant-suitable eye-tracking methods have allowed researchers to consider multiple aspects of attention by precisely measuring <em>when</em> and <em>where</em> infants look, emerging quantitative models of stimulus saliency and computational models of the visual system have deepened our understanding of bottom-up and top-down influences on infant attention, and new methods to evaluate infants’ egocentric views have allowed researchers to measure attention in naturalistic contexts.
