This investigation examined the existence of interconnectedness between developing linguistic subsystems. Spontaneous speech samples were collected from 31 typically-developing Greek-speaking toddlers across two age levels, at 28 and 36 months. Correlational analyses were performed synchronically and predictively, revealing significant positive…

Purpose: This study examines the influence of lexical and phonological factors on expressive lexicon size in 40 French-speaking children tested longitudinally from 22 to 48 months. The factors include those based on the lexical and phonological properties of words in the children's lexicons (phonetic complexity, word length, neighborhood density…

According to the Ecological Model, positive parenting depends on three factors: psychosocial context, the children's needs and parental competences. This cross-sectional study analyzes parental competences, perception of efficacy and parenting satisfaction, among Spanish fathers and mothers with young children aged 0-3 years, and examines their…

Purpose: Our knowledge of speech rate development remains inadequate because of limited longitudinal data and lack of data from children under age 3;0 (years;months). The purpose of this longitudinal study was to test the pattern of speech rate development between ages 2;0 and 3;0. Method: Speech rate was assessed at 4 time points between ages 2;0…

The American Academy of Pediatrics recommends autism spectrum disorder screening at the 18- and 24-month well-child visits. However, despite widespread toddler screening, many children are not diagnosed until school age, and delayed diagnosis is more common among low-income and minority children. Offering autism spectrum disorder screening at…

Autism is often associated with early developmental delays in language and motor skills. However, little is known about the complex dynamic processes that drive the co-development of such early difficulties. The aim of the present study was to model the parallel growth of language and motor skills in a cohort of infants and to explore differences…

Delays in autism spectrum disorder identification/services could impact developmental outcomes. Although trends are encouraging, children from historically underrepresented minority backgrounds are often identified later and have reduced engagement in care. It is unclear if disparities exist throughout the screen-evaluate-treat chain, or if early…

The development of strategies that support autonomous self-regulation of emotion is key for early childhood emotion regulation. Children are thought to transition from predominant reliance on more automatic or interpersonal strategies to reliance on more effortful, autonomous strategies as they develop cognitive skills that can be recruited for…

Objective: The tendency to vocalize toward objects is ubiquitous among young infants. However, little is known about the range of this tendency and its contribution to language development. Therefore, this longitudinal study objective was to explore the role of three forms of vocal behavior (vocalization, babbling, and speech) directed toward…

Infants can help and share in the second year of life. However, there is limited knowledge as to variability in these behaviors as a function of target (e.g., caregiver vs. unfamiliar adult) and the influence of caregiver support on infant prosocial behavior. Infants (N = 268, 124 female) at 1-2 years of age (M = 1.47, SD = 0.27) and again at 2-3…

The number of older siblings a child has is negatively correlated with the child's verbal skills, an effect that is well known in the literature. However, few studies have examined the effect of older siblings' sex, of the age gap between siblings, of having foreign-speaking parents, as well as the mediating role of parental interaction. Using…

This study described infant/toddler teachers' (N = 106) perceptions of stress intensity and exhaustion (emotional, physical, mental) intensity. We examined the associations between stress and exhaustion and teachers' reports of stress sources and coping strategy use. Using ecological momentary assessment (EMA), teachers from Early Head Start…

In successful communication, it is critical to have the ability to identify what a speaker is referring to from previously mentioned information. This ability requires the identification of the topic initially introduced by lexical forms and its continuity in discourse expressed by anaphora such as null and pronominal forms in the subsequent…

The current study investigated longitudinal associations between parent-rated temperament, observed exuberance and accelerometer activity level at 18-months and symptoms of ASD and ADHD at 36-months in a sample of 54 children at elevated likelihood for ASD. For the specific parent-rated temperament scales, most observed significant associations…

Preliminary findings from a follow-up study of 33 children, assessed for their socioemotional development from 18 months of age, are presented. At 77 months, they were evaluated again in a laboratory context, recording on video a situation of discussion of a conflict with the caregiver and then coding these videos using the CIB instrument.…
