Given the rich bound morphology of Spoken Arabic, an attempt was made here to construct a developmental measure corresponding to the mean length utterance (MLU) in English and to morpheme-per-utterance (MPU) in Hebrew. The adaptation to Arabic resulted in a new measurement termed Arabic-MPU, that was experimentally tested on a sample of 98…

Purpose: This study reexamines the claim that difficulty forming memories of words comprising uncommon sound sequences (i.e., low phonological neighborhood density words) is a determinant of delayed expressive vocabulary development (e.g., Stokes, 2014). Method: We modeled communicative development inventory data from (N = 442) 18-month-old…

Studies investigating the development of tense/aspect in children with developmental disorders have focused on production frequency and/or relied on short spontaneous speech samples. How children with developmental disorders use future forms/constructions is also unknown. The current study expands this literature by examining frequency,…

The Structured Observation System (SOS) is a data collection method developed to document changes in the communication behaviours of children identified with speech and language delays. The system employs a rating scale which reflects the occurrence of communication behaviours as well as the amount of assistance needed for behaviours to occur.…

The receptive and expressive "wh" interrogative performance of 20 language-delayed children (4.3 to 6.4 years old) was compared to available normative data. These findings suggest that the delayed children develop the same order of acquisition and rules for questioning as normal children, but at a slower rate. (Author/SEW)

Although child maltreatment has often been described as leading to language deficits, the few well-controlled investigations of language acquisition in maltreated children have focused on language content rather than form, or have used qualitative rather than quantitative measures. This study examines syntactic complexity in 19 maltreated and 14…

This is the second report of a longitudinal project, initiated in 1970, in which children with and without language problems are identified in French immersion and English kindergartens and closely monitored to the end of grade 3. This study investigates the desirability of early French immersion program for English-speaking children with language…
