The present study examined the dyadic nature of fathers' and mothers' reported frequency of storybook reading by testing (1) the longitudinal association in parents' frequency of storybook reading when their children were 10.47 months old and 52.95 months old, (2) the interdependence between both parents' reported frequency of storybook reading,…

This study investigated the associations between maternal depression when infants were 3 to 11 months old (M = 6 months), and positive parenting behaviors when children were between 12 and 22 months (M = 17 months) and the home language environment assessed when children were 18 to 28 months old (M = 23.5 months) in a sample of 29 low-income…

A qualified and dedicated early care and education (ECE) professional workforce is essential for the well-being of our youngest children. Despite the importance of ECE professionals, the field continues to experience challenges recruiting and retaining individuals in the workforce, often due to high expectations for early care with inadequate…

Only about 10 percent of eligible infants and toddlers with developmental delays nationwide receive early intervention services, which are widely agreed to reduce delays and lessen the adverse effects of risk factors and disabilities on learning and development. California serves fewer children than the national average. Challenges arise from…

The development of theory of mind (ToM) in infancy has been mainly documented through studies conducted on a single age group with a single task. Very few studies have examined ToM abilities other than false belief, and very few studies have used a within-subjects design. During 2 testing sessions, infants aged 14 and 18 months old were…

Previous research shows that English-learning 7.5-month-olds are biased to segment speech at strong syllables consistent with the predominant trochaic (strong-weak) pattern of words in their language (Jusczyk, Houston, & Newsome, 1999). The present study asked whether 7.5-month-olds can use a familiar name to override their metrical bias and…

Currently, Developmental scales for children aged 0-6 years are a particularly valuable resource for assessing developmental milestones in children. Most scales are developed based on a broad conceptual framework, and their metric validation is insufficient and of low quality. The aim of this systematic review is to analyse the psychometric…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

While changing demographics reflect an increasingly multicultural and multilingual U.S. population, Latinos continue to experience under-representation and lack of recognition inconsistent for such a growing segment of the U.S. population. Latinos face a myriad of inequities across systems that impact early childhood development and that continue…

Infants are precocious word learners, and seem to possess systematic expectations about how words refer to object kinds. For example, while monolingual infants show a one-to-one mapping bias (e.g. mutual exclusivity), expecting each object to have only one basic level label, previous research has shown that this is less robust in bi- and…

Infants learning languages with long consonants, or geminates, have been found to "overselect" and "overproduce" these consonants in early words and also to commonly omit the word-initial consonant. A production study with thirty Italian children recorded at 1;3 and 1;9 strongly confirmed both of these tendencies. To test the…

Both early intervention (EI) programs for infants and toddlers with disabilities and newborn screening (NBS) programs to identify specific disorders shortly after birth rest on the assumption that the best way to prevent or lessen the impact of a disorder is to provide treatment as early as possible. Despite this shared vision, the two programs…

This study aimed to examine the effect of attachment security in 17-month-olds on their peer play interactions and behavioural problems at ages 4 and 6 years, respectively, in Korea. By employing structural equation modelling, we analyzed the data of 183 children and their mothers, which were extracted from the Panel Study on Korean Children…

This study aims at checking the effects of an early intervention program (EIP) on the neuropsychomotor development (NPMD) and quality of life (QoL) of 4-18 months old babies attending daycare, following the biopsychosocial (BPS) model of health and the International Classification of Functioning Disability and Health (ICF). It was a…

This study analyses variation sets in a sample of child-directed speech (CDS) in Turkish in terms of their structure and effect on child speech. The term "variation set" was first introduced to describe the sequences of repetitions, in which the intention behind expressions stays the same throughout the whole conversation while the form…
