A multiple baseline across behaviors single-subject experimental design was used to determine if selected parameters of speech prosody were modified by an intensive training program administered over nine days to a six-year-old language impaired child. The training yielded positive results indicating that prosodic skills are modifiable. (Author/DB)

Two experiments examined young children's sensitivity to linguistic contexts in which particular function morphemes occur. Results showed that children who did not produce articles in spontaneous speech were able to distinguish between sentences, verbally presented in picture identification tasks, that contained grammatical articles and those that…

Acoustic analyses, along with perceptual ratings, measured the extent to which preschoolers imitated three modeled intonation contours (declarative, interrogative, and monotone). Results indicated that five-year-old children imitated modeled contours more frequently than did three-year-old children, with between-group differences largely because…

Investigated functional differences between the accent-lending rise followed by sustained level pitch (10) and combined accent-lending rise and final rise (12) in Dutch. Thirty individuals were presented with short utterances bearing either a 10 or 12 contour. Results indicated that 10 is not readily interpreted as a question, so 10 may help…

Examined mandibular correlates of prosodic control in nonread dialog exchange involving repeated corrections. Articulatory and acoustic data were collected from four American English speakers at an x-ray laboratory, measuring jaw opening. Results suggested a local and global use of the jaw-opening gesture to produce both linguistic or…

Examines the effects of prosodic variation (vocal affect) on the type of inferences six- and nine-year-old children made about a speaker's communicative intent. Demonstrates that children's interpretations of potentially ironic utterances were influenced by prosody, and the nature of this influence differed by age. (SR)

A study investigated prosodic variables of syllable stress and intonation contours in speech produced during the simultaneous communication (SC) of ten hearing sign language users. Results indicated longer sentence duration for SC than speech only conditions. Vowel duration and frequency differences between stressed and unstressed syllables were…

This study examined the right hemisphere contribution to the production of linguistic prosody where acoustic features of prosodic structures in different linguistic contexts were examined accompanied by perceptual judgements. When control and right hemisphere damaged (RHD) subjects were asked to produce lexical stress differences (Experiment 1),…

Stress assignment to three- and four-syllable Italian words is not predictable by rule, but needs lexical look-up. The present study investigated whether stress assignment to low-frequency Italian words is determined by stress regularity, or by the number of words sharing the final phonological segment and the stress pattern (stress neighborhood…

A comparison of the contour alignment of nuclear and initial prenuclear accents was carried out for the Irish dialects of Gaoth Dobhair in Ulster (GD-U) and Cois Fharraige in Connaught (CF-C). This was done across conditions where the number of unstressed syllables following the nuclear and preceding the initial prenuclear accents was varied from…

While the critical importance of phonological awareness (segmental phonology) to reading ability is well established, the potential role of prosody (suprasegmental phonology) in reading development has only recently been explored. This study examined the relationship between children's prosodic skills and reading ability. Hierarchical multiple…

An expressive disturbance of speech prosody has long been associated with idiopathic Parkinson's disease (PD), but little is known about the impact of dysprosody on vocal-prosodic communication from the perspective of "listeners." Recordings of healthy adults ("n" = 12) and adults with mild to moderate PD ("n" = 21) were elicited in four speech…

Many languages exhibit constraints on prosodic words, where lexical items must be composed of at least two moras of structure, or a binary foot. Demuth and Fee (1995) proposed that children demonstrate early sensitivity to word-minimality effects, exhibiting a period of vowel lengthening or vowel epenthesis if coda consonants cannot be produced.…

This paper investigates the acquisition of prosodic words in European Portuguese (EP) through analysis of grammatical and statistical properties of the target language and child speech. The analysis of grammatical properties shows that there are solid cues to the prosodic word (PW) in EP, and the presence of early word-based phonology in child…

While individuals with autism spectrum disorders (ASD) are typically impaired in interpreting the communicative intent of others, little is known about the neural bases of higher-level pragmatic impairments. Here, we used functional MRI (fMRI) to examine the neural circuitry underlying deficits in understanding irony in high-functioning children…
