A normative-speaker validation study of two indices developed to quantify tongue dorsum activity from midsagittal tongue shapes.
This study reported adult scores on two measures of tongue shape, based on midsagittal tongue shape data from ultrasound imaging. One of the measures quantified the extent of tongue dorsum excursion, and the other measure represented the place of maximal excursion. Data from six adult speakers of Scottish Standard English without speech disorders were analyzed. The stimuli included a range of consonants in consonant-vowel sequences, with the vowels /a/ and /i/. The measures reliably distinguished between articulations with and without tongue dorsum excursion, and produced robust results on lingual coarticulation of the con...

Tracking change in children with severe and persisting speech difficulties.
Abstract Standardised tests of whole-word accuracy are popular in the speech pathology and developmental psychology literature as measures of children's speech performance. However, they may not be sensitive enough to measure changes in speech output in children with severe and persisting speech difficulties (SPSD). To identify the best ways of doing this, we compared a range of commonly used procedures for perceptual phonological and phonetic analysis of developmental speech difficulties. Data are drawn from four children with SPSD, recorded at 4 years and again at 6 years old performing naming and repetition tas...

The influence of the frequency of functional markers on repetitive imitation of syntactic constructions in children with specific language impairment, from their own language productions.
In this study, we focus specifically on the influence of the frequency of functional words on the ability of children with SLI to produce grammatical constructions based on the children's own previous production but containing previously unused functional words. To test our hypothesis, the children were administered an imitative repetition task, tailored to their current level of language development. Results showed that children with SLI performed more poorly than language-matched children with typical language development. The difference between the two groups was more marked when the previously unused functional words w...

Intervention for improving comprehension in 4-6 year old children with specific language impairment: practicing inferencing is a good thing.
ier C Abstract Few studies report on therapy to improve language comprehension in children with specific language impairment (SLI). We address this gap by measuring the effect of a systematic intervention to improve inferential comprehension using dialogic reading tasks in conjunction with pre-determined questions and cues. Sixteen children with a diagnosis of SLI aged 4-6 participated in 10 weekly treatment sessions carried out by their regular therapists. Baseline and maintenance periods were also tabulated. Two experimental measures and a standardized test revealed that children's total scores and the quality o...

The impact of extrinsic demographic factors on Cantonese speech acquisition.
This study modeled the associations between extrinsic demographic factors and children's speech acquisition in Hong Kong Cantonese. The speech of 937 Cantonese-speaking children aged 2;4 to 6;7 in Hong Kong was assessed using a standardized speech test. Demographic information regarding household income, paternal education, maternal education, presence of siblings and having a domestic helper as the main caregiver was collected via parent questionnaires. After controlling for age and sex, higher maternal education and higher household income were significantly associated with better speech skills; however, these variables ...

Speech perception and lexical effects in specific language impairment.
Abstract Using an identification task, we examined lexical effects on the perception of vowel duration as a cue to final consonant voicing in 12 children with specific language impairment (SLI) and 13 age-matched (6;6-9;6) peers with typical language development (TLD). Naturally recorded CV/t/sets [word-word (WW), nonword-nonword (NN), word-nonword (WN) and nonword-word (NW)] were edited to create four 12-step continua. Both groups used duration as an identification cue but it was a weaker cue for children with SLI. For NN, WN and NW continua, children with SLI demonstrated certainty at shorter vowel durations tha...

Sentence comprehension in Swahili-English bilingual agrammatic speakers.
Abstract For this study, sentence comprehension was tested in Swahili-English bilingual agrammatic speakers. The sentences were controlled for four factors: (1) order of the arguments (base vs. derived); (2) embedding (declarative vs. relative sentences); (3) overt use of the relative pronoun "who"; (4) language (English and Swahili). Two theories were tested: the Trace Deletion Hypothesis (TDH; [Grodzinsky, Y. (1995). A restrictive theory of agrammatic comprehension. Brain and Language, 50, 27-51]) that assumes a representational deficit in agrammatic aphasia and the Derived Order Problem Hypothesis (DO...

The relationship of phonological skills to language skills in Spanish-English-speaking bilingual children.
;a ED Abstract These two studies investigate the relationship between phonological production skills and performance in other domains of language in Spanish-English-speaking bilingual children. We examine the relationship between scores on a single-word phonology test and language measures selected from formal testing and narrative samples in Spanish and English. The first study explores the language and phonology scores of 186 children (mean age  =  5 years, 9 months) who represent a range of language ability levels. Phonology scores in both languages were most strongly correlated with per...

Language processing in children with cochlear implants: a preliminary report on lexical access for production and comprehension.
Abstract In this plenary paper, we present a review of language research in children with cochlear implants along with an outline of a 5-year project designed to examine the lexical access for production and recognition. The project will use auditory priming, picture naming with auditory or visual interfering stimuli (Picture-Word Interference and Picture-Picture Interference, respectively) and eye tracking paradigms to examine the roles of semantic and various phonological factors. Preliminary data are presented from auditory priming, picture-word interference and picture-picture interference tasks. The emergence...

Early phonological development: creating an assessment test.
Abstract This paper describes a new protocol for assessing the phonological systems of two-year-olds with typical development and older children with delays in vocabulary acquisition. The test (Profiles of Early Expressive Phonological Skills (PEEPS), Williams & Stoel-Gammon, in preparation ) differs from currently available assessments in that age of acquisition, based on lexical norms from the MacArthur-Bates Communicative Developmental Inventories, served as the primary criterion for creating a word list. Phonetic and semantic properties of the words were also considered in selecting items for the test. Pro...

Tongue reading: comparing the interpretation of visual information from inside the mouth, from electropalatographic and ultrasound displays of speech sounds.
This study aimed to determine whether there is any intuitive ability to interpret the images produced by these systems, and to determine whether one tool is more conducive to this than the other. Twenty adults viewed real-time and slow motion EPG and ultrasound silent movies of 10 different linguo-palatal consonants and 4 vowels. Participants selected which segment they perceived from four forced-choice options. Overall, participants scored above chance in the EPG and ultrasound conditions, suggesting that these images can be interpreted intuitively to some degree. This was the case for consonants in both the conditions an...

Tongue-palate contact of perceptually acceptable alveolar stops.
Abstract Increased tongue-palate contact for perceptually acceptable alveolar stops has been observed in children with speech sound disorders (SSD). This is a retrospective study that further investigated this issue by using quantitative measures to compare the target alveolar stops /t/, /d/ and /n/ produced in words by nine children with SSD (20 tokens of /t/, 13 /d/ and 11 /n/) to those produced by eight typical children (32 /t/, 24 /d/ and 16 /n/). The results showed that children with SSD had significantly higher percent contact than the typical children for target /t/; the difference for /d/ and /n/ was not s...

Subject pronoun use by children with autism spectrum disorders (ASD).
Abstract In the current study, storytelling and story retelling by children with autism spectrum disorder (ASD) were analyzed to explore ambiguous third-person pronoun use in narratives. Twenty-three children diagnosed with ASD aged 6;1 to 14;3 and 17 typically-developing (TD) children aged 5;11 to 14;4 participated in the study. In the retelling task, no significant difference between the groups was found, suggesting that in less challenging tasks, children with ASD produce third-person subject pronouns appropriately. In the storytelling task, children with ASD produced more ambiguous third-person subject pronoun...

Agrammatism in Jordanian-Arabic speakers.
This study investigated the production of morpho-syntactic elements in 15 Jordanian-Arabic (JA) speaking individuals with agrammatism and 15 age-matched neurologically healthy individuals. Two experiments were conducted to examine the production of complementizer, tense, agreement and negation morphology in JA. The results indicated that the speakers of JA with agrammatism had marked dissociations in producing specific morpho-syntactic elements. The observed impairment patterns overlapped, in many respects, with those observed in other linguistic groups. The findings are discussed with respect to current theories of agramm...

The formulation of argument structure in SLI: an eye-movement study.
This study investigated the formulation of verb argument structure in Catalan- and Spanish-speaking children with specific language impairment (SLI) and typically developing age-matched controls. We compared how language production can be guided by conceptual factors, such as the organization of the entities participating in an event and knowledge regarding argument structure. Eleven children with SLI (aged 3;8 to 6;6) and eleven control children participated in an eye-tracking experiment in which participants had to describe events with different argument structure in the presence of visual scenes. Picture descriptions, l...

Speech and pause characteristics in multiple sclerosis: A preliminary study of speakers with high and low neuropsychological test performance.
Abstract This preliminary study investigated how cognitive-linguistic status in multiple sclerosis (MS) is reflected in two speech tasks (i.e. oral reading, narrative) that differ in cognitive-linguistic demand. Twenty individuals with MS were selected to comprise High and Low performance groups based on clinical tests of executive function and information processing speed and efficiency. Ten healthy controls were included for comparison. Speech samples were audio-recorded and measures of global speech timing were obtained. Results indicated predicted differences in global speech timing (i.e. speech rate and pause...

Sentence repetition as a measure of morphosyntax in monolingual and bilingual children.
Abstract Bilingual children are frequently misdiagnosed as having Specific Language Impairment (SLI). Misdiagnosis may be minimized by tests with high degrees of sensitivity and specificity. The current study used a new test, the School-Age Sentence Imitation Test-English 32 (SASIT-E32), to investigate sentence repetition in monolingual and bilingual children, and specifically to compare overall repetition accuracy and error patterns in the two groups. Eighteen English-speaking monolingual children (mean age = 8;8) and 18 Farsi-English bilingual children (8;2) participated. Monolingual children repea...
