The purpose of this study is to describe the use of recorded music in child care centers during naptime. Using a cross-sectional survey design, administrators and teachers from 62 child care centers in Louisiana responded to an online questionnaire designed to gather information about children's sleep habits and teacher perceptions of music…

The emotional availability scales (EAS), 4th edition, are widely used in research and clinical practice to assess the quality of parent-child interaction. This study examined the short-term reliability and continuity of the EAS (4th ed.) assessed in two similar observational contexts over a one-week interval. Sixty-two Dutch parents (85% mothers)…

Hyper-articulation of vowel and consonant contrasts is often reported in infant-directed speech (IDS), but is not universal cross-linguistically, and may be a side-effect of speaking rate. This study investigated the voicing characteristics of the four-way oral stop voicing contrast in Nepali IDS. Both lead and lag time of word-onset/g,…

Prenatal maternal depression affects both mother and fetus with long-term implications for offspring vulnerability to psychopathology through alterations to brain development, stress physiology, negative emotionality, and cognitive control. This article reviews evidence for the negative impact of prenatal maternal depression on offspring…

While there is a great body of research regarding inclusion of children with disabilities in educational settings, inquiry regarding inclusion for children under the age of five is comparatively much less robust. More children with developmental delays, learning differences, and disabilities are attending traditional early care and early education…

Purpose: This experimental study examined term infants (n = 34) and low-risk near-term preterm infants (gestational age 32-36 weeks) at 2 months chronological age (n = 34) and corrected age (n = 16). The study investigated whether the preterm infants presented with a delay in their sensitivity to synchronous syllable-object pairings when compared…

Prior research suggests that infants' action production affects their action understanding, but little is known about the aspects of motor experience that render these effects. In Study 1, the relative contributions of self-produced (n = 30) and observational (n = 30) action experience on 3-month-old infants' action understanding was…

Evaluating initiatives implemented across multiple settings can elucidate how various contextual factors may influence both implementation and outcomes. Understanding context is especially critical when the same program has varying levels of success across settings. We present a framework for evaluating contextual factors affecting an initiative…

Infants are born primed to develop attachment relationships. However, when infants are hospitalized in the neonatal intensive care unit at birth, the stress and trauma associated with the highly specialized medical environment can threaten the development of a nurturing and secure caregiving relationship. Infant mental health is an evidence-based…

Parents modulate their speech and their actions during infant-directed interactions, and these modulations facilitate infants' language and action learning, respectively. But do these behaviors and their benefits cross these modality boundaries? We investigated mothers' infant-directed speech and actions while they demonstrated the action-effects…

Human infants show a robust preference for speech over many other sounds, helping them learn language and interact with others. Lacking a preference for speech may underlie some language and social-pragmatic difficulties in children with ASD. But, it is unclear how an early speech preference supports later language and social-pragmatic abilities.…

Behavioral research has shown that 12- but not 9-month-olds imitate an unusual and inefficient action (turning on a lamp with one's forehead) more when the model's hands are free. Rational-imitation accounts suggest that infants evaluate actions based on the rationality principle, that is, they expect people to choose efficient means to achieve a…

Each infant is born with music potential, and early exposure to music and social music interactions may positively affect music development. Researchers have found that infants perceive music, attend to music, respond to music, and engage in social music interactions. Caregivers may enhance their music practices by deepening their infant music…

Caregivers' sensitive responses to infant cry have long-term consequences for adaptive child development. Although mounting evidence suggests that parents who experience high emotionality to infant cry respond less sensitively to infant cry, there is a dearth of knowledge on potential mechanisms underlying individual differences in emotionality to…

Societal perspectives on male circumcision and its implications are not well understood. In this exploratory qualitative study, participants (N = 34, 7 male, 27 female) enrolled in a human sexuality course were asked to share their perspectives on male circumcision through the development of a written response to open-ended questions. Written…
