This case study examined prosodic use in a normally developing child between the ages of 20 and 46 months. Conversational repairs were elicited to examine prosodic stress. Fundamental frequency, intensity, and duration of syllables were measured. Although the subject could repair stress errors, a clear pattern of the development of acoustic cues…

Two case examples (a toddler with severe developmental delays and a 7-year old with severe mental retardation) illustrating effects of meal schedule and food quantity on displays of problematic behavior are offered. Brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior. (DB)

This article reviews the developmental profile of a child with autism during the first 3 years of life. Analysis of home videos showed how the child appeared to make progress up to 12 months followed by decreases in social interaction, communication, and language. Discussion suggests that this particular profile is one of the possible pathways…

This case study of a toddler with autism whose parents had videotaped her development from birth showed that the child's behavior and development were essentially normal for the first year but that she then became withdrawn in only a few months. It is suggested that early communicative screening tests might have identified the child's earliest…

Early vocal development, consonant production, and spoken vocabulary were examined in a deaf toddler whose multichannel cochlear implant was activated at 20 months. The child understood almost 240 words and spoke approximately 90 words after one year of implant experience. The combination of early cochlear implantation, family support, and regular…

Discussion of the functional relationship between self-injurious behavior (SIB) and self-restraint in people with severe disabilities considers SIB and self-restraint as members of the same functional response class, SIB and self-restraint as functionally independent responses, access to self-restraint as positive reinforcement of SIB, termination…
