This paper examined the fundamental frequency variation in the narratives of individuals with high-functioning autism (HFA) and typical controls matched on age, IQ, and verbal abilities. Study 1 found increased fundamental frequency variation in the speech of 21 children and adolescents with HFA when compared to 21 typical controls. Study 2 replicated the findings from Study 1 with a younger sample of 17 children with HFA and 17 typical controls. In addition, Study 1 found evidence that acoustic measurements of prosody were related to clinical judgments of autism-specific communication impairments, although this was not replicated in Study 2. Taken together, these studies provide evidence for differences in expressive prosody in individuals with HFA that can be measured objectively.

This cross-linguistic comparison of metalinguistic development in French and English examines early ability to manipulate derivational suffixes in oral language games as a function of chronological age, receptive vocabulary, and year of schooling. Data from judgment and production tasks are presented for children aged between 5 and 8 years in their first, second, or third school year in the United Kingdom and France. The results suggest that metamorphological development is accelerated in French relative to English. The French advantage encompasses knowledge of a broader range of suffixes and a markedly greater facility for generalizing morphological knowledge to novel contexts. These findings are interpreted in relation to the word formation systems of English and French, and the educational context in each country.

The generality of the orthographic consistency effect in speech recognition tasks previously reported for Portuguese beginning readers was assessed in French-speaking children, as the French orthographic code presents a higher degree of inconsistency than the Portuguese one. Although the findings obtained with the French second graders replicated the generalized consistency effect (both for words and pseudowords, in both lexical decision and shadowing) displayed by the Portuguese second to fourth graders, the data obtained with the French third and fourth graders resembled the adult pattern, with the orthographic effect restricted to lexical decision. This suggests that, in the course of literacy acquisition, the overall orthographic inconsistency of the language's orthographic code influences the rate at which orthographic representations will impact on spoken word recognition.

In six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity between print and speech by using the words say, name, and word to refer to both spoken and written language. Parents could differentiate writing and drawing by making syntactic and semantic distinctions in their discussion of the two symbol systems. Our results indicate that parent speech includes these types of information. However, young children themselves sometimes confuse writing and drawing in their speech.

The role of phonological short-term memory (PSTM), attentional resource capacity/allocation, and processing speed on children's spoken narrative comprehension was investigated. Sixty-seven children (6–11 years) completed a digit span task (PSTM), concurrent verbal processing and storage (CPS) task (resource capacity/allocation), auditory–visual reaction time (AVRT) task (processing speed), and the Test of Narrative Language. Correlation and regression analyses examined the association between the memory variables and comprehension. The main findings were (a) CPS and AVRT correlated with comprehension and (b) after accounting for age, CPS accounted for a significant 7.9% of unique variance and AVRT accounted for another significant 5.2%. The results indicate that resource capacity/allocation and processing speed are important to children's ability to understand spoken narrative.

Our goal was to investigate auditory and speech perception abilities of children with and without reading disability (RD) and associations between auditory, speech perception, reading, and spelling skills. Participants were 9-year-old, Finnish-speaking children with RD (N = 30) and typically reading children (N = 30). Results showed significant group differences between the groups in phoneme duration discrimination but not in perception of amplitude modulation and rise time. Correlations among rise time discrimination, phoneme duration, and spelling accuracy were found for children with RD. Those children with poor rise time discrimination were also poor in phoneme duration discrimination and in spelling. Results suggest that auditory processing abilities could, at least in some children, affect speech perception skills, which in turn would lead to phonological processing deficits and dyslexia.

This study aimed to investigate cognate/noncognate processing distinctions in young adult bilinguals and examined whether the previously reported cognate facilitation effect would also be demonstrated in older adult bilinguals. Two groups of Italian–English bilingual participants performed lexical decisions in repetition priming experiments. Results for the younger bilinguals corresponded to previous findings, and indicated the expected reaction time advantage for cognates over noncognates. The older bilinguals, however, only demonstrated a cognate advantage in the within-language condition, and in fact, showed faster reaction times for noncognates when repetition was across languages. These findings are interpreted in the context of the revised hierarchical model and the bilingual interactive activation model and in light of findings regarding the effect of aging on language processing.
