This study reports various aspects of the analyses carried out on the longitudinal data reported in a previous study (PS 007 345) for determining the general growth patterns and growth velocity of mental and motor development. Preliminary analyses focused on the selection of the growth curve, its evaluation in the 208 individual cases, and the…

Learning in infancy is based on activity, beginnings, and curiosity, the so-called ABC's. Earliest behavior consists of mass activity, the period from birth to 24 months of sensory-motor development which provides the foundation for all future learning. Adults must provide space, toys, and affectionate care to help infants proceed through…

The early communication network existing between a mother and her 12-week-old infant was explored. Over 50 infants of both sexes from a variety of social classes were seen in their homes, and a wide variety of maternal and infant behaviors were studied. Of special interest was the vocalization-in-communication data. The results indicate a lawful,…

Programmed instructional training materials in orientation and mobility were developed and field tested with 22 multiply handicapped blind infants and toddlers functioning between ages 0 and 3. Children receiving intervention from trainers using these materials demonstrated significant performance gains over control subjects in cognitive…

The article describes and illustrates data collection methods useful in establishing social interaction objectives for improving the quantity and quality of parent social interactions with their handicapped infants. Among these are visual analysis of relationship patterns across intervention sessions, and the use of percentage for describing…

Using a longitudinal design, investigates the interactive behaviors of mothers of normal infants and mothers of infants who are known to differ on a host of cognitive, behavioral, and biological parameters. Examines the developmental course of emotional expressivity in these infants. (HOD)

Investigates the antecedents of individual differences in cognitive/language competence for 121 24-month-olds who were also assessed at 6 and 13 months. Warm verbal interactions between mother and child at three ages were associated with child competence at 24 months. Socioeconomic status was also modestly correlated. (Author/CB)

A parent education program aimed at promoting cognitive development in 150 2- and 3-year-olds of Black and Hispanic families was instituted in both a pediatric clinic of a general hospital and a child health station in the community. (Author)

Challenging the prevailing belief that the first 3 years of a child's life comprise the most critical period for development, this book maintains that although there is valid scientific evidence for the existence of critical periods, the same research points to learning and development occurring throughout life. The book asserts that too many…

Noting that all parents can help their baby's brain to grow, this guide, in English- and Spanish-language versions, explores what science has learned about infant brain development and how parents and caregivers can influence cognitive development. Topics covered include: prenatal care, touching your baby, teaching about feelings and self-control,…

The interaction of biological and social factors on the mental and psychological development of 114 low-bIrth-weight premature infants from primarily poor and non White urban families was studied. It is suggested that premature infants are more vulnerable to environmental insufficiencies than are full-term babies. Journal Availability: American…

Reviews studies comparing short- and long-term effects of language-based socially and cognitively interactive play enrichment in day care and the home during infancy. Found that both day care and home children experiencing intervention advanced to high levels of language and cognitive functioning compared to control children. Advantages of home…

This longitudinal study examined the hypothesis that two different types of joint-attention skills were related to verbal and nonverbal IQ measures through middle childhood. Subjects were infants born preterm and tested at 13 months and at 8 years. Findings provide support for the hypothesis that the initiation of joint attention makes a unique…

Investigates levels and patterns of intellectual development of 131 socioeconomically disadvantaged children in university-based intervention group day care or community day care, or with little or no day care. Results suggest that high quality day care may positively change the intellectual development of socioeconomically disadvantaged children.…

Outlines infants' and preschoolers' implicit protoquantitative reasoning schemas and shows how these combine with early counting knowledge to produce mathematical concepts of number. Reviews research on elementary school children's informal and invented arithmetic, and evaluates implications for mathematics education. (Author/BJV)
