The purpose of the current project is to explore the use of propensity scores to estimate the effects of interventions within randomized control trials, accounting for varying levels of implementation or fidelity. This work extends that of Jo and Stuart (2009) to settings with multiple or continuous measures of implementation. Rather than focus…

Although infantile amnesia has been investigated for many years in adults, only recently has it been investigated in children. This study was a 2-year follow-up and extension of an earlier study. Children (4-13 years old) were asked initially and 2 years later for their earliest 3 memories. At follow-up, their age at the time of these memories…

Parents may be reluctant to treat the feeding disorder of a chronically ill child who exhibits distressed behavior during feeding. In this study, we identified a child with chronic medical problems and a feeding disorder who cried during feedings. We introduced treatment components sequentially to address parental concerns about crying. First, we…

Speech scientists have long proposed that formant exaggeration in infant-directed speech plays an important role in language acquisition. This event-related potential (ERP) study investigated neural coding of formant-exaggerated speech in 6-12-month-old infants. Two synthetic /i/ vowels were presented in alternating blocks to test the effects of…

In adults, native language phonology has strong perceptual effects. Previous work has shown that Japanese speakers, unlike French speakers, break up illegal sequences of consonants with illusory vowels: they report hearing "abna" as "abuna". To study the development of phonological grammar, we compared Japanese and French infants in a…

McCarty and colleagues (1999) developed the elevated spoon task to measure motor planning in human infants. In this task, a spoon containing food was placed on an elevated apparatus that supported both ends of the spoon. The handle was oriented to the left or right on different trials. We presented naive adult rhesus monkeys (Macaca mulatta) with…

The developmental outcomes for children born preterm have been examined by many, with results unequivocally indicating that children born preterm tend to have poorer cognitive outcomes and more developmental difficulties. Less attention has been paid to academic outcomes. The purpose of this paper is to review the academic skills assessment of…

Two percent of women in the United States suffer from intimate partner violence annually, with poor and minority women disproportionately affected. I provide evidence of an important negative externality associated with domestic violence by estimating a negative and causal relationship between violence during pregnancy and newborn health,…

Purpose: This article describes guiding principles in early intervention (EI) and demonstrates how speech-language pathologists (SLPs) can apply these principles to best serve infants and toddlers with communication and related problems and their families. Method: Four principles guide the implementation of speech-language pathology services. EI…

Infants can use statistical regularities to form rudimentary word categories (e.g. noun, verb), and to learn the meanings common to words from those categories. Using an artificial language methodology, we probed the mechanisms by which two types of statistical cues (distributional and phonological regularities) affect word learning. Because…

Few experimental studies investigate the mechanisms by which young children develop sex-typed activity preferences. Gender self-labeling followed by selective imitation of same-sex models currently is considered a primary socialization mechanism. Research with prenatally androgenized girls and non-human primates also suggests an innate male…

Considerable evidence indicates that shape similarity plays a major role in object recognition, identification and categorization. However, little is known about shape processing and its development. Across four experiments, we addressed two related questions. First, what makes objects similar in shape? Second, how does the processing of shape…

This study assessed whether two persons with developmental disabilities would be able to actively perform simple occupational activities by controlling their favorite environmental stimulation using battery-free wireless mice with a newly developed object location detection program (OLDP, i.e., a new software program turning a battery-free…

The February 2011 National Early Hearing Detection and Intervention (EHDI) conference marked its tenth annual event. During the opening plenary, speakers looked back and described the progress and accomplishments of past years. They highlighted activities of the various federal agencies, medical organizations, and individuals who helped move EHDI…

As adults, we know that others' mental states, such as beliefs, guide their behavior and that these mental states can deviate from reality. Researchers have examined whether young children possess adult-like theory of mind by focusing on their understanding about others' false beliefs. The present research revealed that 10-month-old infants seemed…
