Güven, Selçuk; Leonard, Laurence B. – International Journal of Language & Communication Disorders, 2020
Background: Turkish has a rich system of noun suffixes, and although its complex suffixation system may seem daunting, it can actually present a learning opportunity for children. Despite its unique features, Turkish has not been studied extensively, especially in the case of children with language deficits, such as developmental language disorder…

Leonard, Laurence B. – First Language, 2016
Noun-related morphosyntax has not been emphasized in the literature on children with specific language impairment (SLI), yet, across languages, problems in this area are quite apparent. This review is designed to highlight noun-related difficulties that seem to be especially troublesome for these children. A review of the research literature on…

Lukács, Ágnes; Kas, Bence; Leonard, Laurence B. – First Language, 2013
This study examines whether children with specific language impairment (SLI) acquiring a language with a rich case marking system (Hungarian) have difficulty with case, and, if so, whether the difficulty is comparable for spatial and nonspatial meanings. Data were drawn from narrative samples and from a sentence repetition task. Suffixes were…

Lukacs, Agnes; Leonard, Laurence B.; Kas, Bence – International Journal of Language & Communication Disorders, 2010
Background: Children with language impairment often exhibit significant difficulty in the use of grammatical morphology. Although English-speaking children with language impairment have special difficulties with verb morphology, noun morphology can also be problematic in languages of a different typology. Aims: Hungarian is an agglutinating…

Factors Accounting for the Ability of Children with SLI to Learn Agreement Morphemes in Intervention
Pawlowska, Monika; Leonard, Laurence B.; Camarata, Stephen M.; Brown, Barbara; Camarata, Mary N. – Journal of Child Language, 2008
The aim of this study was to uncover factors accounting for the ability of children with specific language impairment (SLI) to learn agreement morphemes in intervention. Twenty-five children with SLI who participated in a six-month intervention program focused on teaching third person singular -s or auxiliary "is"/"are"/"was" showed a wide range…

Hsieh, Li; Leonard, Laurence B.; Swanson, Lori – Journal of Child Language, 1999
Examined input frequency, sentence position, and duration as contributing factors to grammatical inflections. In parents' conversations with and stories aimed at young children, noun plural inflections were more frequent than third singular verb inflections, especially in sentence-final position. Analysis of four mothers' speech when reading…

McGregor, Karla K.; Leonard, Laurence B. – Journal of Speech and Hearing Research, 1994
Children with specific language impairment (SLI) and their normally developing (ND) peers imitated proper nouns, the pronouns "he" and "you," and the article "the" in subject phrases. Both groups showed significantly more omissions of the function words than the proper nouns. A phonological explanation of subject article and pronoun omission is…

Leonard, Laurence B.; Miller, Carol; Gerber, Erika – Journal of Speech, Language, and Hearing Research, 1999
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.…

Leonard, Laurence B.; Salameh, Eva-Kristina; Hansson, Kristina – Applied Psycholinguistics, 2001
Examined the use of noun phrase morphology by preschool-age children with specific language impairment (SLI) who were also acquiring Swedish. Relative to typically developing same-age peers and younger peers matched according to mean length of utterance, the children with SLI had greater difficulty in the use of genitive inflections, indefinite…

Camarata, Stephen M.; Leonard, Laurence B. – Papers and Reports on Child Language Development, 1985
In a study of very young children's pronunciation of nouns and verbs, ten children aged 20 to 25 months were exposed to experimental nouns and verbs, which had not yet been comprehended or produced by the children. Each of the objects and actions was given an experimental name based on phonemes in the children's speech. These objects and actions…

Ihns, Mary; Leonard, Laurence B. – Journal of Child Language, 1988
Examination of a two-year-old's early determiner-noun combinations suggested that early article use can be distributed across a variety of nouns, and that such usage does not seem appropriately characterized as a pattern of limited semantic scope. (CB)
