This study addresses the question of how age of acquisition (AoA) affects grammatical processing, specifically with respect to inflectional morphology, in bilinguals. We examined experimental data of more than 100 participants from the Russian/German community in Berlin, all of whom acquired Russian from birth and German at different ages. Using…

This study investigates phenomena that have been claimed to be indicative of Specific Language Impairment (SLI) in German, focusing on subject-verb agreement marking. Longitudinal data from fourteen German-speaking children with SLI, seven monolingual and seven Turkish-German successive bilingual children, were examined. We found similar patterns…

This study investigates the ability of a group of eight Greek-speaking adolescents with Down Syndrome (DS) (aged 12.1-18.7) to handle the perfective past tense using an acceptability judgement task. The performance of the DS participants was compared with that of 16 typically-developing children whose chronological age was matched with the mental…

Does the language processing system make use of abstract grammatical categories and representations that are not directly visible from the surface form of a linguistic expression? This study examines stem-formation processes and conjugation classes, a case of "pure" morphology that provides insight into the role of grammatical structure in…

This study reports results from four experiments investigating the perfective past tense of Greek in adult second language (L2) learners. The data come from L2 learners of Greek with intermediate to advanced L2 proficiency and different native language (L1) backgrounds, and L1 speakers of Greek. All participants were tested in both oral and…

Argues that to improve the parameter model as a theory of language acquisition it has to be constrained in several ways. Results on the acquisition of subject-verb agreement, verb placement, empty subjects, and negation in German child language are presented. (55 references) (JL)

This study presents results from sentence-completion and grammaticality-judgement tasks with seven German-speaking agrammatic aphasics and seven age-matched control subjects examining verb finiteness marking and verb-second (V2) placement. The patients were found to be selectively impaired in tense marking in the face of preserved mood and…

This study presents results from sentence-completion and grammaticality-judgment tasks with 7 German-speaking agrammatic aphasics and 7 age-matched control subjects examining tense and subject-verb agreement marking. For both experimental tasks, we found that the aphasics achieved high correctness scores for agreement, while tense marking was…

Examined the representation of phrase structure in early child German through the investigation of longitudinal data from seven German-speaking toddlers with respect to verb placement, verb inflection, negation, /wh/ pronouns, and complementizers. It is argued that children construct phrase-structure trees in a gradual fashion, on the basis of…

Suggests that differences between first- and second-language learners are due to principles of universal grammar (UG) that guide first language (L1), but not second language (L2) acquisition. This view can be reconciled with the idea that L2 learners can use UG principles to some extent in evaluating target sentences. (49 references) (Author/VWL)
