Prader-Willi syndrome (PWS), most recognized for the hallmark hyperphagia and food preoccupations, is caused by the absence of expression of the paternally active genes in the q11-13 region of chromosome 15. Since the recognition of PWS as a genetic disorder, most research has focused primarily on the medical, genetic, and behavioral aspects of…

Joint attention (JA) skills are deficient in children with autism; however, children with autism seem to vary in the degree to which they display joint attention. Joint attention skills refer to verbal and nonverbal skills used to share experiences with others. They include gestures such as pointing, coordinated looks between objects and people,…

Purpose: The impact of a newly designed computer-assisted treatment ("C-AT") program, "My Sentence Builder", for the remediation of expressive-grammar deficits in children with specific language impairment (SLI) was explored. This program was specifically designed with features to directly address expressive-grammar difficulties, thought to be…

Purpose: The intent of this study was to examine the longitudinal morpho-syntactic progression of children with Speech Sound Disorders (SSD) grouped according to Mean Length of Utterance (MLU) scores. Methods: Thirty-seven children separated into four clusters were assessed in their pre-kindergarten and Grade 1 years. Cluster 1 were children with…

The aim of this longitudinal study was to obtain information on the early lexical development and its predictive value to language skills in very-low-birth-weight (VLBW) children. The MacArthur Communicative Development Inventory was used to collect data of the early receptive and expressive lexicon of the 32 VLBW children. This information was…

This study examined the feasibility of using a dialogic book-reading intervention for 22-r41-month-old bilingual preschool children with expressive vocabulary delays. The intervention was provided in English and Spanish concurrently to an experimental group of six children, while six other children were in a delayed treatment control group. Thirty…

The study examined differences in the distribution of spectral energy among four types of infant vocalizations via computerized spectral analyses. The mean spectral energy (MSE) of "pain induced" cries was significantly higher than those of "fussy" and "hungry" cries, and the MSE of all three cries was higher than…

The effect of semantic grouping on confrontation-naming performances of 16 fluent and 10 nonfluent aphasic adults was examined. Performances were not uniformly facilitated in one naming condition over the other. Some patients, however, did appear to display performance discrepancies between the two conditions. (Author/CL)

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

The study analyzed the temporal delays and pauses associated with neologisms produced by Finnish posterior aphasics. Delays and pauses appeared to correlate with the type of neology they preceded. (Author)

Five profoundly deaf adults were recorded reading lists of individual words under three expressive modes (speech alone, speech and signs, and speech with cues). Results indicated that speech with cues produced the highest level of intelligibility, speech and signs the lowest. (Author/CL)

The study examined the expressive communicability (i.e., the amount, fluency, elaboration, clarity, and veracity of voluntarily transmitted information about oneself) and belief systems of 30 hospitalized adult schizophrenics and 30 matched normals. Schizophrenics differed from normals on all measures and the different beliefs predicted expressed…

Topic continuing and nontopic continuing utterances produced by three productively language-disordered preschoolers were analyzed. Results suggested that Ss produced a proportion of adjacent utterances comparable to proportions previously reported for children with normal production language skills and that they relied on an imitation strategy to…

This study measured naming reaction times of 40 normal or reading disordered (RD) children to picture stimuli of varying vocabulary age and spatial dimension. Dimension appeared to differentiate between the two groups with the control group faster in naming three-dimensional pictures and the RD group faster in naming two-dimensional stimuli. RD…

Gains made by a woman with Broca's aphasia as documented by traditional measures were paralleled by changes in conversation, including increased verbal output and efficiency, and changes in conversation-repair patterns. The progress documented with conversational discourse analysis was not observable from other test measures. (Author/DB)
