This volume sheds empirical light on Complex Dynamic Systems Theory (CDST) by providing five sets of analyses of two longitudinal, interactional datasets, involving two dyads exchanging emails over one academic semester. The collective study on CDST is the first of its kind, in that it delves into multiple subsystems of learner language,…

This study examined difficulties in the use of -ed as passive participle or as past tense in 12 young children with specific language impairment. Results suggest that either the surface properties of -ed are related to the difficulty or these children have a separate, non-tense- related deficit in the area of verb morphology. (Contains…

Evaluation of the grammatical morphology used by 50 preschool children with specific language impairment as a function of their lexical diversity found their use of finite-verb morphology (based on number of different verbs used) and noun-related morphology lagged behind expectations in comparison to a group of normally developing preschoolers.…

The study found that eight specifically language-impaired children (ages four and five) were more limited than eight normally developing children (ages two and three, matched for mean utterance length) in the use of both subject case marking and verb morphology. A relationship between the two types of usage was found in both groups of children.…

This study used grammaticality judgments to measure the sensitivity of four school-age children with severe speech and physical impairments (SSPI) to different morphological errors. Results indicated that the SSPI children and control groups made similar judgments. Participants with SSPI had greater difficulty detecting tense-marking errors…

A study of the use of the complex Finnish morphological rule system in 45 children, aged 20-24 months, examined the children's inflection of nouns and verbs in speech characteristic of everyday Finnish. Analysis of the correct, unanswered, and incorrect test items found six classes of errors, which were then examined for clues to the underlying…

Discusses grammar and spelling instruction in The Netherlands for students aged 10-15 and describes an intelligent computer-assisted instructional environment consisting of a linguistic expert system, a didactic module, and a student interface. Three prototypes are described: BOUWSTEEN and COGO for analyzing sentences, and TDTDT for conjugating…
