Sound symbolism, the iconic link between speech sounds and meanings, helps children's verb learning. In sound symbolically rich languages such as Turkish, hearing sound symbolic words might facilitate early verb learning and later language-specific expressions of motion events, by providing an easier way to map verbs onto events. These links could…

The purpose of this study is to investigate the relations among children's symbolic functioning at 15 months, joint attention at 24 months, expressive communication at 24 and 36 months, and executive functioning at 36 months. With the sample from rural areas in the United States collected by the Family Life Project (N = 1,008), a longitudinal data…

This study tested infants' ability to segregate target speech from a background of ecologically valid multi-talker speech at a 10 dB SNR. Using the Headturn Preference Procedure, 72 English-learning 5-, 9-, and 12-month-old monolinguals were tested on their ability to detect and perceive their own name. At all three ages infants were able to…

Researchers can study complex developmental phenomena with all the inherent noise and complexity or simplify behaviors to hone in on the essential aspects of a phenomenon. We used the development of walking as a model system to compare the costs and benefits of simplifying a complex, noisy behavior. Traditionally, researchers simplify infant…

Recent work asked if visual cues facilitate word segmentation in adults and infants (Thiessen, 2010). While adults showed better word segmentation when presented with a regular visual cue (consistent mapping between words and objects), infants did not. This difference was attributed to infants' lack of understanding that objects have labels.…

Epigenetic regulation of the placental glucocorticoid receptor gene ("NR3C1") was investigated as a mechanism underlying links between maternal smoking during pregnancy (MSDP) and infant neurobehavior in 45 mother-infant pairs (49% MSDP-exposed; 52% minorities; ages 18-35). The Neonatal Intensive Care Unit (NICU) Network Neurobehavioral…

Children with complex congenital heart defects often show delays and deficits in cognitive, language, motor, and social-emotional functioning. As such, the American Academy of Pediatrics and the American Heart Associated recommend ongoing monitoring and support of development. In conjunction with the formal therapeutic supports frequently…

This study investigates the practice of "sounding for others," wherein one person vocalizes to enact someone else's putatively ongoing bodily sensation. We argue that it constitutes a collaborative way of performing sensorial experiences. Examples include producing cries with others' strain or pain and parents sounding an "mmm"…

Mental State Language (MSL) is language that refers to individuals' inner states, including terms relating to "emotion," "desire-&-preference," "perception" and "cognition." This study explores the nature of eight Chinese educators' MSL in their interactions with infants during structured and free play.…

Evidence shows individual variation in lexical acquisition as a function of socioeconomic status and linguistic input. Research has primarily involved English-speaking populations and considered only mothers' child-directed speech. This study analyzes the effects of socioeconomic status on quantitative and qualitative properties of linguistic…

Background: Fathers' mental health, parenting practices and co-parenting relationships have a powerful effect on child development. The paucity of research on the parenting strengths and support needs of fathers of children across childhood and adolescence compels the current study addressing the parenting experiences of a large sample of fathers…

Research Findings: This study examined whether teacher-child interaction quality varied as a function of type of activity in toddler classrooms in four European countries (Finland, Netherlands, Poland, and Portugal). It also investigated whether specific activity settings, namely levels of adult involvement, use of whole group, and children's…

Traditional provider-to-child models of early intervention (EI) service provision have been increasingly replaced by service guidelines that promote a broader family-centered approach to support improvement in the child's primary area of delay. These guidelines include working directly with caregivers and addressing needs of the family that might…

Along with the late 1980s Medicaid expansion for pregnant women and children, states implemented multiple reforms to reduce administrative burdens and facilitate access to Medicaid and prenatal care. We use National Vital Statistics birth data from 1985 to 1994 and a difference-in-discontinuities approach to compare the effectiveness of these…

The purpose of this study was to examine the frequency and quality of primary care physician (PCP) recommendations to investigate the management of young children with delays and self-injury (SIB; e.g., head banging) from the time of initial SIB concern to specialty referral as recommended by the American Academy of Pediatrics (AAP). Via a…
