The conferencee discussions and papers presented in this volume reflect the opinions and research of 20 authorities in the field of communication development. These authorities offer new perspectives on nonverbal communication, speech reception and production, and the development of language and thought. To provide a better understanding of…

In an effort to look at factors moderating the negative effects of preterm low birthweight and perinatal illness, the study followed up (at 7 and 12 months of age) 50 preterm infants whose cumulative morbidity score was greater than 100 and/or who had a life threatening complication. Home visits provided ratings of maternal sensitivity, the…

This demonstration study examines the affective reactions of infants when they imitate or fail to imitate play behavior modeled by an adult. Subjects were twenty-four 18-month-old and twenty-four 24-month-old male and female infants. Each infant visited the laboratory twice with an inter-session interval of 48 hours. At each session, the infant…

Reviews different approaches used over the past two decades to study early behavioral development in infants. Reviews research in areas as physical and cognitive development and the role of adult caretakers. (BD)

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this Spanish-language pamphlet provides parents with information and advice about their infants in the sixth month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics,…

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this Spanish-language pamphlet provides parents with information and advice about their infants in the eighth month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics,…

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this pamphlet provides parents with information and advice about their infants in the eleventh month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics, including:…

Distributed by the U.S. Departments of Agriculture, Education, and Health and Human Services, this Spanish-language pamphlet provides parents with information and advice about their infants in the ninth month of life. Following a brief description of developmental characteristics at this age, the pamphlet offers advice on a variety of topics,…

This study examined behavioral development during the first year of life of 41 infants diagnosed with cerebral palsy, hypotonia, or hypertonia. The KID Scale, an empirically normed, caregiver-report inventory which covers behavior in five domains (cognitive, motor, language, self help, and social) was administered at about 5, 9, and 12 months…

The accuracy of a risk index based on reproductive and demographic factors for predicting subsequent development was tested with 51 full-term and 53 preterm infants. In addition, the possibility that scores on the Home Observation for Measurement of the Environment scale might contribute significantly to the prediction of subsequent development…

The behavioral development of rural Guatemalan infants was assessed shortly after birth on a Neonatal Assessment Scale (NAS) and at 6-, 15-, and 24-months-of-age on a Composite Infant Scale (CIS). Summary variables based on NAS performance poorly predicted later assessed performance even as recently as six months after birth. The CIS modestly…

Used heart rate and respiratory sinus arrhythmia (RSA) assessed at 33 to 35 weeks gestational age to predict developmental outcome at 3 years for very low birth weight infants. Found that RSA measures predicted developmental outcome beyond effects of birth weight, medical risk, and socioeconomic status. For infants < 1,000 grams, RSA maturation…

Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…

Two experiments tracked infants' eye movements to examine use of word-initial information to understand fluent speech. Results indicated that 21- and 18-month-olds recognized partial words as quickly and reliably as whole words. Infants' productive vocabulary and reaction time were related to word recognition accuracy. Results show that…
