A meta-analysis was carried out of interventions for children with primary developmental speech and language delays/disorders. The data were categorized depending on the control group used in the study (no treatment, general stimulation, or routine speech and language therapy) and were considered in terms of the effects of intervention on…

Children with specific language impairment (SLI) have associated difficulties in reading decoding and reading comprehension. To date, few research studies have examined the children's written language. The aim of the present study was to (a) evaluate the nature and extent of the children's difficulties with writing and (b) investigate the…

Despite the common use of mean length of utterance (MLU) as a diagnostic measure, what it actually reflects in terms of linguistic knowledge is relatively unclear. This study explored the extent to which variance in MLU could be accounted for by a measure of expressive vocabulary and a measure of morphosyntax in a group of 44 typically-developing…

Complex complements are clausal objects containing tensed verbs (e.g., that she cried) or infinitives (e.g., to cry), following main verbs of communication or mental activities (e.g., say, want). This research examined whether English- and Cantonese-speaking 4-year-olds' complement understanding uniquely predicts their representation of other…

Although there is extensive documentation of the morphological limitations of children with specific language impairment (SLI), few studies have reported on complex syntax acquisition in children with SLI. This case study examined the development of complex syntax in a child with SLI between 3 and 7 years. Twelve conversational samples were…

This article focuses on word order - the order of constituents in the sentence - as one way in which languages establish the relationship between a verb and its arguments. The spoken languages of the world have been classified into three, major word-order types: SVO, VSO, and SOV. Greenberg' work (1963) on language typology has been a stimulus to…

Five experiments, using a subject-verb agreement error elicitation procedure, investigated syntactic planning processes in production. The experiments examined the influence of semantic integration--the degree to which phrases are tightly linked at the conceptual level--and contrasted two accounts of planning: serial stack-based systems and…

This article is concerned with the correspondence conditions that hold between certain semantic relations--including part-whole relations, possession, location, and the semantic features [+- animate] or [+- count]--and certain syntactic structures including genitives and relative clauses. The objective is to determine the extent to which these…

In many areas of language acquisition, researchers have suggested that semantic generality plays an important role in determining the order of acquisition of particular lexical forms. However, generality is typically confounded with the effects of input frequency and it is therefore unclear to what extent semantic generality or input frequency…

We conducted two word-by-word reading experiments to investigate the timing of implausibility detection for recipient and instrument prepositional phrases (PPs). These PPs differ in thematic role, relative frequency, and possibly in argument status. The results showed a difference in the timing of garden path effects such that the detection of…

Event-related potentials were recorded to substantiate the claim of a distinct psycholinguistic status of (a) pronouns vs. proper names and (b) ellipses vs. proper names. In two studies 41 students read sentences in which the number of intervening words between the anaphor and its antecedent was either small or large. Comparing the far with the…

The present investigation is a study of the definitional style of nouns and verbs in typically developing school-age children. A total of 30 children in upper-elementary grades provided verbal definitions for 10 common high-frequency nouns (e.g., apple, boat, baby) and 10 common high- frequency verbs (e.g., climb, sing, throw). All definitions…

In this cross-sectional investigation, syntactic development was compared in conversational versus expository discourse in 120 typically developing children, adolescents, and adults, age 7 to 49 years. Each participant was asked to discuss common topics such as school, family, and friends to elicit conversational discourse and to explain the rules…

Background: In reading research, children with specific language impairment (SLI) have tended to be included in groups of children expected to have difficulties with both decoding and reading comprehension (generally poor readers). This is because generally children with specific language impairment display difficulties with phonology as well as…

This study was an investigation of several Arabic reading measures among dyslexics and normal Arabic readers across different ages (grades 3, 6, 9, and 12): the role of morphology, short vowelization (phonological and syntactic skills), spelling, reading isolated words, and reading comprehension. The results of the one-way ANOVAs indicated clear…
