In noun compounds in English, the modifying noun may be singular ("mouse-eater") or an irregularly inflected plural ("mice-eater"), but regularly inflected plurals are dispreferred (*"rats-eater"). This phenomenon has been taken as strong evidence for dual-mechanism theories of lexical representations, which hold that regular (rule-governed) and…

This paper addresses the problem of learning the class of raising verbs (e.g. seem). These verbs are potentially problematic for learners in that unlike typical main verbs, these verbs do not stand in a semantic relation with any Noun Phrase (NP) arguments. Moreover, a second class of verbs, known as control verbs, shares certain distributional…

We examined infants' recognition of functors and the accuracy of the representations that infants construct of the perceived word forms. Auditory stimuli were "Functor + Content Word" versus "Nonsense Functor + Content Word" sequences. Eight-, 11-, and 13-month-old infants heard both real functors and matched nonsense functors (prosodically…

Few studies have focused on mechanisms of developmental change during the prelinguistic period. The lack of focus on early vocal development is surprising given that maternal responsiveness to infants during the first two years has been found to influence later language development. In addition, in a variety of species, social feedback is…

This article is about the contributions children make in clinical interviews. This issue is studied by re-analysing a selection of the empirical excerpts used by Piaget in his seminal book The Child's Conception of the World. The focus is on how children use language non-literally, and especially on how they use meta-communicative markers ("as…

The acquisition of noun gender on articles was studied in a sample of 21 young German-speaking children. Longitudinal spontaneous speech data were used. Data analysis is based on 22 two-hourly speech samples per child from 6 children between 1 ; 4 and 3 ; 8 and on 5 two-hourly speech samples per child from 15 children between 1 ; 4 and 2 ; 10. The…

This paper focuses on the aspects of the lexicon in 66 prematurely born very-low-birth-weight and 87 full-term Finnish children at 2;0, studied using the Finnish version of the "MacArthur Communicative Developmental Inventory". The groups did not differ in vocabulary size. Furthermore, the female advantage in vocabulary size was not seen…

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.…

From the beginning of life, a child's acts of meaning are joint constructions, enacted through dialogue between himself and a significant other by reference to whom he is achieving a personal identity. When the child begins to control his material environment, he begins the transition to systematic symbolic construction. At the same time, he is…

This study investigated the nature and extent of differences in young children's talk when they interact with mothers and peers. Sixteen girls between 2.5 and 3.5 years of age played twice with their mothers and twice with a peer. Play sessions were videotaped and coded according to measures of quantity and quality of talk. Results of measures of…

A study investigating the acquisition of empty categories (ECs) in Sinhala, a language of the Indo-Aryan family spoken in Sri Lanka, is reported in part. The results examined here concern ECs occurring in a subset of adverbial clause types differing with regard to the kinds of null subjects they permit, including those obligatorily coindexed,…

This examination focuses on the idea that child language acquisition is constrained by the same principles that have been found to hold on syllable structure across languages. First, a recently-proposed constraint on syllable structure, the Sonority Cycle, is outlined, and the way that it accounts for syllabic structure across languages is…

A study investigated children's use of three acoustic parameters (intensity, fundamental frequency, and duration) in the production of two-syllable nonsense words. Subjects were six children each at ages 2, 3, and 4 years with age-appropriate language skills and normal hearing sensitivity. An examiner produced eight novel two-syllable words of…

Designed to grade children's knowledge of commonly used instructional terms in a particular language arts program, the AIT consists of a verbal part and a situational part. Each part assesses the same commonly used instructional terms: word, begin, letter, name, makes sense, beginning sounds, print, trace, capital letter, rhyme, period, stands…

The use of observation of natural language interaction as a measure of language proficiency and the impact of discourse characteristics on children's use of Spanish and English as measured by length of utterances are examined. The goal of this observational approach to measuring language proficiency is to distinguish between the effects of change…
