Children with specific language impairment (SLI) have well-documented problems in the use of tense-related grammatical morphemes. However, in English, tense often overlaps with aspect and modality. In this study, 15 children with SLI (mean age 5;2) and two groups of 15 typically developing children (mean ages 3;6 and 5;3) were compared in terms of…

The purpose of this research was to show how the syntactic and semantic components of the tense-aspect system interact during the acquisition process. Our methodology involved: (1) identifying predicates, (2) finding the initial occurrence of their tense-aspect morphology, and (3) observing the emergence of contrasts. Six children learning Polish…

Examines the development of children's knowledge about the presuppositions of cognitive verbs that take sentential complements. Results indicate that the presuppositions of the factives "know,""forget," and "remember" and the nonfactive "think" are not learned until age four. "Believe," which has factive and nonfactive properties, is mastered…

This study is an attempt to investigate the efficacy of using existing semantic relations categories for understanding how children comprehend the verb "with" + noun construction. (Author)

Reports on a study of the acquisition of personal inflections in Portuguese, and presents an analysis of the speech of one of the children followed in the longitudinal study. (AM)

Explores the interaction between the timing of verb models and the focus of the events to which they refer on verb learning by children. Findings revealed that the movement verb was learned better in the impending condition and the result verb in the completed condition. (seven references) (Author/CK)

Greek has two verbs of agency that can be used interchangeably to mean "to look for." Examined whether children will obey the principle of contrast to diagnose that one verb is mentalistic and the other is to be construed behaviorally. A study of mothers' verb use confirmed that the verb preferred in home use gave below chance performance on a…

A longitudinal study examined two-year-olds' acquisition of the English auxiliary system after a six-week exposure to additional auxiliary input in varying sentence contexts. Results indicated that subjects did not significantly differ from a baseline group that did not receive additional input. (Author/CB)

In a study of event knowledge, 13 2-year-olds were observed interacting with their mothers over a 5-month period. Results indicated that children's increasing event knowledge facilitated their language development (e.g., lexical type use, action verb use) and their lexical token use. (Contains 33 references.)

Presents an analysis of past tense and participle usages by children, focusing on overapplications of irregular vowel-change patterns, as in "brang"; blends, as in "branged"; productive suffixations of "-en," as in "walken"; gross distortions, as in "mail-membled"; and double-suffixation, as in "walkeded." Findings indicate that these errors are…

Investigated the first verbs to participate in verb-object and subject-verb-object combinations and the temporal parameters of the spread of these combinations over different verbs, observing longitudinally young children acquiring English and Hebrew. Results indicated that the more verbs children already knew to combine in a certain pattern, the…

This paper focuses on aspects of early lexical acquisition in German. There have been conflicting results in the literature concerning both the pattern of vocabulary growth and the composition of the early lexicon. Our study describes the development of various categories of words and questions the preponderance of nouns in spontaneous speech. 32…

The present research investigated whether children's referential choices for verb arguments are motivated by pragmatic features of discourse referents across different developmental stages, not only for children learning null argument languages but also for those learning overt argument languages. In Study 1, the form (null, pronominal, or…

Reports a study which examines some of the properties of objects to determine whether the number of different examples of an object concept presented to infants influences concept learning and generalization and to discover whether children's behavior and language in relation to new objects influence learning the concept and generalization to new…

This study aimed to determine the average ages at which children imitate, produce and comprehend passive constructions. Previous findings that imitation precedes comprehension, which precedes production, are confirmed in this study for children aged 3-8. (CHK)
