Science, Technology, Engineering, and Math (STEM) education is essential to the economic growth, health, and progress of the modern world. One cognitive ability that underpins thinking and learning in STEM, as well as other disciplines, is relational ability. This ability to spot common relations shared by different objects, events, ideas, or…

The home language environment is a significant correlate of early childhood development outcomes; however, less is known about this mechanism in rural and peri-urban China where rates of developmental delay are as high as 52%. This study examines associations between the home language environment and child development in a sample of 158 children…

Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

This doctoral study examined the function of baby massage in supporting early infant-carer attachment relationships among families facing stressful life experiences. It was designed in response to Bennett, Underdown and Barlow's [Bennett, C., A. Underdown, and J. Barlow. 2013. "Massage for Promoting Mental and Physical Health in Typically…

Several concepts exist to explain the human-nature relationship, including nature connection. This paper offers a reconceptualisation of the human-nature bond, based on the infant-parent bond and attachment theory. As such, this paper draws upon research on attachment theory and environmental psychology to draw parallels between the two. Initially…

Early exploratory behaviors have been proposed to facilitate children's learning, impacting motor, cognitive, language, and social development. This study related the performance of behaviors used to explore oneself to behaviors used to explore objects, and then related both types of exploratory behaviors to motor, language, and cognitive measures…

We examined maternal prenatal vitamin use or supplemental folic acid intake during month one of pregnancy for association with autism spectrum disorder (ASD) in the Early Autism Risk Longitudinal Investigation, an enriched-risk pregnancy cohort. Total folic acid intake was calculated from monthly prenatal vitamins, multivitamins, and other…

The present study aimed at investigating the contextual stability, the contextual continuity and the concurrent associations between maternal measures (general language, communicative functions and mind-mindedness) and child measures (total number of word types and tokens) in two different contexts, free-play and mealtime. To this purpose, the…

Purpose: The aim of this study was to investigate infants' listening preference for emotional prosodies in spoken words and identify their acoustic correlates. Method: Forty-six 3- to-12-month-old infants (M[subscript age] = 7.6 months) completed a central fixation (or look-to-listen) paradigm in which four emotional prosodies (happy, sad, angry,…

Search filters are used to find evidence on specific subjects. Performance of filters can be varied and may need adapting to meet the needs of research topics. There are limited geographic search filters available, and only one pertaining to low- and middle-income countries (LMICs). When searching for literature on preterm birth prevention and…

Purpose: Current models of speech development argue for an early link between speech production and perception in infants. Recent data show that young infants (at 4-6 months) preferentially attend to speech sounds (vowels) with infant vocal properties compared to those with adult vocal properties, suggesting the presence of special "memory…

This qualitative descriptive study was designed to answer the following questions: How do infant/toddler teachers (ITTs) enter the infant/toddler workforce? What motivates teachers to work in the infant/toddler workforce? What recruitment strategies are identified by experienced ITTs? What retention strategies are identified by experienced ITTs?…

The purpose of this research was to organize a cross-cultural adaptation study and analyze the reproducibility and test-retest reliability of the Infant Sensory Profile 2 (ISP2Br) to Brazilian babies. It was hypothesized that the instrument would be validated for use with Brazilian babies. The English language version of the profile was translated…

Purpose: Limited quantitative data exist regarding growth of the velopharynx within the first 2 years of life. The purpose of this study was to (a) quantify changes in velopharyngeal structures due to growth during the first 2 years of life, (b) examine the impact of sex and race within this age range, and (c) provide normative measures for…

Medical personnel play a critical role in caregiver safe infant sleep education. However, training outcomes in the safe infant sleep training literature have been mixed. Promising approaches that warrant further investigation are the use of behavioral skills training and pyramidal training. The current study consisted of two experiments.…
