The paper maintains that impact evaluation studies of programs serving handicapped infants and preschoolers should be restricted to scientifically defendable investigations. Specific types of impact studies and an evaluation process are suggested. It is suggested that program leaders should focus evaluation activities on the status of project…

The study evaluated the Batelle Developmental Inventory (BDI) with 40 disabled children under 30 months of age. Subjects were also given the Bayley Scales and Vine Scales of Adaptive Behavior. Results indicated high concurrent validity, interrater reliability, and internal consistency for the BDI. (Author/DB)

The 1987-88 annual report reviews progress on 17 longitudinal studies to determine the efficacy of early intervention with handicapped children. The overview chapter reviews previous research on this topic; considers ethical, practical, and scientific considerations of randomized experiments in early childhood special education; examines benefits…

This bibliographic review aims to present a single comprehensive source of references to facilitate clinical application of data obtained on the vocal activity of normal infants and to facilitate continued research on prelinguistic vocal output. The bibliography cites the published observational, empirical, and theoretical reports that examine the…

This study evaluated the Bielefeld Developmental Test for Blind Infants and Preschoolers by comparing cognitive performance of blind and sighted children (ages three and four). Results indicated that even this test (with "blind-neutral" items) did not permit a fair comparative assessment, though it did prove suitable for within-group…

Two separate studies suggest that the development of positive sibling relations may be related to siblings' social-cognitive skills (Stewart & Marvin, 1984) and the nature of mothers' conversations with their children (Dunn & Kendrick, 1982). The purpose of the present study was to provide a synthesis of these two studies and to demonstrate the…

Social participation behavior of 33 2- and 3-year-old children was observed during free-play in order to identify differences between age groups as well as differences between contemporary outcomes and Parten's 1932 findings. Trained observers recorded the frequencies of play behaviors, utilizing a time sampling procedure and Parten's categories…

Professionals and 16 mothers of disabled infants/toddlers completed the Evaluation and Programing System-I and the Parent Form Level I, respectively. Results indicated moderate to high correlations between professionals' assessments and mothers' assessments, though mothers tended to rate children higher. (Author/JDD)

This observational study examined the development and use of communication in a pair of deaf and hearing monozygotic twins from 13 to 36 months of age. Both children were enrolled in a total communication preschool program. In contrast to the hearing twin, the deaf twin used imitative (rather than responsive) signs and gestures. (Author/DB)

Analyses of home movies taken by 12 parents before recognition of their children's autistic disorders confirmed that anomalies could be noted as early as the first few months of life, such as anomalies of eye contact, deficient variability of emotional expression, deficit of attention, and initiation of communication, and motor abnormalities.…

Examines effects of age, sex, and sibling status on children's ideas about infants and infant care. The sample consisted of 43 preschoolers and 42 second graders, half of whom were boys, half were girls, and half were singletons. Older children with siblings were more knowledgeable than either their singleton peers or younger children.…

A group of 43 children classified as either behaviorally inhibited or uninhibited at 21 months were observed at four years of age in situations designed to evaluate behavior with an unfamiliar peer, heart rate and heart rate variability to cognitively challenging tasks, reluctance to answer difficult questions, and differential fixation of an…

A study investigated developments in reasoning and memory as reflected by the discovery strategies of children taking part in a manipulative categorization and recall task. A total of 40 children (8 each of 18, 24, 30, 36, and 42 months of age) participated. Stimulus materials consisting of blocks, toy plates, discs, and plastic trees were…

This paper reviews findings from comprehensive early intervention studies with young children with autism and formulates questions that need to be answered to establish efficacious, accessible early treatment. Results suggest that intensive, very early treatment appears to lessen the debilitating effects of autism. Research questions involve…

In order to evaluate possibilities of fitting myoelectrically controlled prosthetic arms on infants, this study examined whether 32 infants (1-6 months) could learn to control environmental contingencies by means of contracting the forearm flexor muscle group. Results indicated that older subjects (age greater than 104 days) demonstrated learning,…
