This study compared mother, infant, and dyad interactions between infants with and without biological risk, considering contextual factors related to the COVID-19 pandemic. Forty-two infants with biological risk and 33 without risk (average age 5.6 months) were evaluated via remote video assessments. Results showed that infants without biological…

Children diagnosed with autism spectrum disorder (ASD) often have smaller vocabularies in infancy compared to typically-developing children. To understand whether their smaller vocabularies stem from problems in learning, our study compared a prospective risk sample of 18 elevated risk and 11 lower risk 24-month-olds on current vocabulary size and…

Purpose: Caregivers of autistic children present with high stress levels, which have been associated with poorer child outcomes in several domains, including language development. However, prior to this study, it was unknown whether elevated caregiver stress was associated with language development in infant siblings of autistic children…

We investigated gestures that parents used with 12-, 18-, and 24-month-old infants at high or low risk for autism spectrum disorder (ASD; high-risk diagnosed with ASD: n = 21; high-risk classified as no ASD: n = 34; low-risk classified as no ASD: n = 34). We also examined infant responses to parent gestures and assessed the extent to which parent…

The topic of the three chapters of this dissertation is empowering caregivers of children with or at high likelihood for autism to implement interventions in home settings with high fidelity to promote their child's social communication development. Chapter 1 provides an overview of the previous studies focused on caregiver-implemented early…

This dissertation investigated the caregiving relationships between infants and nonparental caregivers in early childcare settings through the lens of attachment and language behaviors. This study sought to provide an opportunity to extend our understanding of the socioemotional factors that influence children's development in their daily lives.…

Infant mental health is strongly connected to an infant's relationship with a responsive, warm, and available caregiver. However, maternal mental illness reduces a mother's ability to detect and respond to changes in her infant's expressions and communication, which may have important consequences for infant attachment and emotion regulation. The…

The Minnesota Longitudinal Study of Risk and Adaptation, a 45-year study of children born into poverty, offers a number of lessons for practitioners. Among these are the potency of early relationship experiences for predicting developmental outcomes and the fate of early experience following developmental change. This article describes the…

Social communicative precursors to autism spectrum disorder may influence how infants who are later diagnosed with autism spectrum disorder interact with their social partners and the responses they receive, thus bidirectionally influencing early social experience. This systematic review aimed to identify a developmental timeline for parent-infant…

This study investigated interactions between parents and 12-month-old infants at high (HR-SIBS; n = 27) and low (LR-SIBS; n = 14) familial risk for autism spectrum disorder (ASD). The contributions of parental variables, as well as child's autism symptom severity and verbal skills, to the parent interaction style were examined. Parents of HR-SIBS…

Maternal gatekeeping is characterized by the extent to which mothers engage in behaviors that ultimately serve to inhibit (i.e., gate close) or encourage (i.e., gate open) father involvement in childrearing. This study considered direct and indirect associations between observed and reported maternal gatekeeping and children's social-emotional…

Individuals with sex chromosome trisomies (SCTs) have an increased risk of language delays and impairments. However, there are only a few data relative to their language development in early childhood. The present study aimed to investigate the preverbal skills shown by a group of 8-month-old children with SCTs to assess the presence of a possible…

The estimated number of forcibly displaced persons around the globe is at a record high--nearly 70.8 million (UNHCR 2019)--75 percent of whom are women and children. This includes 34 million adolescent girls and young women, who are among the groups with the highest risk for health concerns. Indeed, many of the countries with the worst maternal…

The purpose of this study was to establish a set of normative data (growth curve and centiles) for the Infant Monitor of vocal Production (IMP) using a representative population of infants with typically developing hearing. A linear mixed effect model and regression was used to derive 'stage-for-age' trajectory and growth centiles from the…

Background: Parent-reported measures of early communication have limitations for use with infants experiencing adversity. Observational measures of early non-verbal and verbal communicative behaviours and mother-child turn-taking may provide a complementary method of capturing early communication skills for these children. Aims: To explore the…
