Infants attune to their birth language during the second half of infancy. However, internationally adopted children are often uniquely required to attune to their birth language, and then reattune to their adoptive language. Children who were adopted from India into America at ages 6-60 months (N = 8) and had minimal further exposure to their…

Every environment contains infinite potential features and correlations among features, or patterns. Detecting valid and learnable patterns in one environment is beneficial for learners because doing so lends predictability to new environments where the same or analogous patterns recur. However, some apparent correlations among features reflect…

Aim: To determine the distribution of cognitive and motor scores in preterm children, and to establish the influence of brain lesions and decreasing gestational age thereon. Method: One hundred and six very preterm children (63 males, 43 females; gestational age 24.0-31.6wk; birthweight 480-2275g) were assessed for cognition and motor outcome at 6…

This study investigates infants' discrimination abilities for familiar and unfamiliar regional English accents. Using a variation of the head-turn preference procedure, 5-month-old infants demonstrated that they were able to distinguish between their own South-West English accent and an unfamiliar Welsh English accent. However, this distinction…

Infants and toddlers are often spoken to in the presence of background sounds, including speech from other talkers. Prior work has suggested that infants 1 year of age and younger can only recognize speech when it is louder than any distracters in the environment. The present study tests 24-month-olds' ability to understand speech in a multitalker…

The two aims of the study were (a) to determine when infants begin to use force intentionally to defend objects to which they might have a claim and (b) to examine the relationship between toddlers' instrumental use of force and their tendencies to make possession claims. Infants' and toddlers' reactions to peers' attempts to take their toys were…

This research examined developmental continuity between "cruising" (moving sideways holding onto furniture for support) and walking. Because cruising and walking involve locomotion in an upright posture, researchers have assumed that cruising is functionally related to walking. Study 1 showed that most infants crawl and cruise concurrently prior…

Recent studies demonstrated that in adults and children recognition of face identity and facial expression mutually interact (Bate, Haslam, & Hodgson, 2009; Spangler, Schwarzer, Korell, & Maier-Karius, 2010). Here, using a familiarization paradigm, we explored the relation between these processes in early infancy, investigating whether 3-month-old…

Pattern perception and organization are critical functions of the visual cognition system. Many organizational processes are available early in life, such that infants as young 3 months of age are able to readily utilize a variety of cues to organize visual patterns. However, other processes are not readily evident in young infants, and their…

Purpose: It is important to ensure that hearing aid fitting strategies for infants take into account the infant's developing speech perception system. As a way of exploring this issue, this study examined how 6- and 9-month-olds with normal hearing perceive native-language speech in which the natural spectral shape was altered to emphasize either…

This study investigated the role of parenting knowledge of infant development in children's subsequent language and pre-literacy skills among White, Black and Latino families of varying socioeconomic status. Data come from 6,150 participants in the Early Childhood Longitudinal Study-Birth Cohort. Mothers' knowledge of infant development was…

The first eight years of life, beginning before birth and continuing through third grade, are a critical developmental period that sets the stage for future success. Research over the past 15 years has demonstrated the importance of high-quality care and education throughout the prenatal-through-third-grade (P-3) continuum, including prenatal and…

Approximately half of all children under the age of three in the United States have a regular child care arrangement (nearly 44 percent of infants from birth to 12 months, 52 percent from 12 to 24 months, and 56 percent from 24 to 36 months; NSECE Project Team, 2015). The percentages of infants and toddlers in center-based care increases with age,…

Background: Recent evidence suggests that impaired foetal growth may provide an early indication of increased risk of child attention problems. However, despite both foetal growth and child attention problems differing by sex, few studies have examined sex differences in this association. Furthermore, no studies have been conducted in low- and…

Early detection methods for autism spectrum disorder (ASD) in infancy are rapidly advancing, yet the development of interventions for infants under two years with or at-risk for ASD remains limited. In order to guide research and practice, this paper systematically reviewed studies investigating interventions for infants under 24 months with or…
