The Early Learner Curriculum and Achievement Record (ELCAR, Greer et al., 2020) is a criterion-referenced curriculum and assessment of children's development of language and social repertoires from the earliest foundational observing responses to advanced verbal repertoires. The developmental cusps or stages identified in the ELCAR have been…

The purpose of this study was to establish a set of normative data (growth curve and centiles) for the Infant Monitor of vocal Production (IMP) using a representative population of infants with typically developing hearing. A linear mixed effect model and regression was used to derive 'stage-for-age' trajectory and growth centiles from the…

Face-to-face communication makes up only a small proportion of an infant's diurnal transactions with his environment, but it is viewed as crucial to his total development. Research was conducted in which adult and infant behaviors were videotaped, and their interactions were analyzed. (Author/HP)

The speech of two mothers to their infants between three and eighteen months was analyzed. Simplicity of speech was about the same at all ages, not showing abrupt change as children began to talk. It is suggested that mothers used a conversational model and changes reflect children's growing conversational ability. (CHK)

Children who learn to speak at an early age have mothers whose basic mode of disciplining is verbal. Charts; bibliography. (AF)

There is a growing awareness today of the critical impact of the preschool years on a child's later academic success. Some studies indicate that many children today are less well prepared for school than were children beginning school 5 years ago. This publication examines what is known about school readiness; discusses the reasons why some…

Home and family conditions were found to have an effect on verbal interaction patterns between mothers and persons in the home. (Authors)

This study showed the effectiveness of two parent education programs designed to increase young children's sustained attention to verbal stimuli. Forty 18- to 24-month-old children and their mothers served as subjects under three different conditions: Full Treatment Program of home training, home visits, group meetings for mothers, and curriculum…

To study the emergence of literacy during the preschool years, a handwritten diary, maintained on a day to day basis, focused on one child, David, from ages two and a half to four and a half. One facet of the study concentrated on his literary language--his incorporation of written texts (children's literature) into his language and background of…

Noting that young children learn to talk at different ages but within certain developmental boundaries, this document presents two charts to help parents facilitate their toddler's speech. The first chart lists characteristics to look for in a growing, healthy baby at various ages between 3 months and 24 months, and suggestions for when to talk to…

This paper describes the linguistic development of two hearing sons of deaf parents. Both were exposed to an early language environment different from that of the average hearing child. At the start of the study, the boys were aged 3 years, 9 months, and 1 year, 8 months, respectively. When first observed, the older child performed well below age…

This study compared mother-child interactions and investigated how child verbal abilities interact with age to influence maternal scaffolding (teaching) styles in a group of 60 mother-child dyads in which the children were aged 3, 4, and 5 years (20 dyads in each of the 3, 4, and 5 year age groups). The mother-child pairs were filmed completing a…

Activities of the Institute for Development of Human Resources provide the information contained in this document. This first large-scale project of the institute was in parent education of disadvantaged mothers in the north central Florida area. The purpose of the project was to investigate a way in which early intervention into the lives of…

A comprehensive bibliography on linguistic input in the home, clinic, and/or classroom is presented. Three general categories of materials are included: language spoken to normal children, cross-cultural studies, and language spoken to special populations. Linguistic input is a term that refers to the special language register that parents use to…

A discussion of word acquisition rates and strategies is based upon a 6-month case study of an Estonian-speaking child who gradually and systematically relaxed phonotactic constraints to allow greater complexity in word production. In addition to the cognitive tools of assimilation and accomodation as described by Piaget, the child used a further…
