Method: We compared the vocabulary and general language trajectories of the two groups in two ways:…

In this series of experiments, we tested the limits of young infants' word learning and generalization abilities in light of recent findings reporting sophisticated word learning abilities in the first year of life. Ten-month-old infants were trained with two word-object pairs and tested with either the same or different members of the…

Previous research has shown that the quality of mother-child interactions between pre-term children and their mothers tends to be poorer than that of full-term children and their mothers (Forcada-Guex, Pierrehumbert, Borghini, Moessinger & Muller-Nix, 2006). Mothers of pre-term children are less responsive and more intrusive in interactions…

Background: Progress monitoring is a vital strategy for evaluating skill development of young children receiving disability related services.

Objective: The current study examined the implementation of an…

B. F. Skinner is the most eminent psychologist of the twentieth century, and it is no exaggeration to say that his discovery of operant learning (conditioning) has influenced the broader field of psychology, as well as other disciplines, including education, neuroscience, and philosophy.

The Modified Checklist for Autism in Toddlers (M-CHAT) is a screening questionnaire for Autism Spectrum Disorder (ASD). Previous findings have confirmed the M-CHAT's sensitivity and specificity across several cultures, yet few studies have considered M-CHAT scores as a distributed trait in a sample of typical infants. The current study examined…

The Individuals with Disabilities Education Act (IDEA) requires states to monitor and enforce IDEA Part C and Part B requirements, with a primary focus on those requirements that are most closely related to improving results and functional outcomes for infants, toddlers, and children with disabilities. This guide describes the IDEA requirements…

Consistent, sensitive caregiving across home and childcare contexts supports optimal development. In this paper, we share the story of the development of Hearts and Minds on Babies (HMB) for Early Head Start (EHS) administrators, teachers, and parents. HMB was designed to support caregiver reflective functioning and sensitivity and reduce…

There is no relationship more vital than the one a child shares with their primary caregivers early in development. Yet many children worldwide are raised in settings that lack the warmth, connection, and stimulation provided by a responsive primary caregiver. In this study, we used data from the Bucharest Early Intervention Project (BEIP), a…

Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…
