An evaluation measure (EM) guides a learner's choice of grammar when more than one is compatible with available input. EM must be universal, so children receiving comparable input acquire comparable grammars. It must favor the choices children actually make. The theoretical shift from rule-based grammars to principles-and-parameter-based grammars…

A paradox at the heart of language acquisition research is that, to achieve adult-like competence, children must acquire the ability to generalize verbs into non-attested structures, while avoiding utterances that are deemed ungrammatical by native speakers. For example, children must learn that, to denote the reversal of an action,…

Two experiments examined preschoolers' ability to learn novel words using others' expertise about objects' nonobvious properties. In Experiment 1, 4-year-olds (n = 24) endorsed individuals' labels for objects based on their differing causal knowledge about those objects. Experiment 2 examined the robustness of this inference and its development.…

Purpose: The purpose of this study was to contribute to the current understanding of how children with specific language impairment (SLI) organize their mental lexicons. The study examined semantic and phonological priming in children with and without SLI. Method: Thirteen children (7;0-11;3 [years;months]) with SLI and 13 age-matched children…

This study examined the ability of 20 preschool children with functional phonological delays and 34 age- and vocabulary-matched typical children to learn words differing in phonotactic probability (i.e., the likelihood of occurrence of a sound sequence) and neighborhood density (i.e., the number of words that differ from a target by one phoneme).…

An eye-movement monitoring experiment investigated readers' response to temporarily ambiguous sentences. The sentences were ambiguous because a relative clause could attach to one of two preceding nouns. Semantic information disambiguated the sentences. Working memory considerations predict an overall preference for the second of the two nouns, as…

The authors identify 2 major types of statistical data from which semantic representations can be learned. These are denoted as "experiential data" and "distributional data". Experiential data are derived by way of experience with the physical world and comprise the sensory-motor data obtained through sense receptors. Distributional data, by…

Matching-to-sample and sequence training procedures were used to develop responding to stimulus classes that were considered analogous to 3 aspects of verbal behavior: identifying synonyms and parts of speech,and using syntax. Matching-to-sample procedures were used to train 12 paired associates from among 24 stimuli. These pairs were analogous to…

Types of utterances (with locative action utterances specifically differentiated) were evaluated in a language-impaired child tracked between one year, six months and three years of age. Comparison with utterances in other children suggests the importance of such a fine-grained analysis in detecting semantic properties of child language…

This article discusses word definitions within the context of language development in school-age children and adolescents. It explains the importance of the ability to define words, reviews the growth of word definition during school years, describes standardized tests, and offers suggestions for expanding the normative database for word…

Improvements in English-language skills made by hearing-impaired students can be assessed using the taxonomy of semantic development phases from L. Bloom and M. Lahey. Teachers are encouraged to transcribe, code, and analyze bimodal language samples and to write both form and content language objectives for hearing-impaired students. (JDD)

It is recommended that auditory-verbal clinicians working with children with hearing impairments and their families use a battery of specific language tests when providing an early intervention program that focuses on language growth. These multiple measures should include norm-and criterion-referenced instruments that specifically measure…

The report presents information from a survey of the needs and characteristics of children with severe communication disorders in Ontario and the programs available to serve them. It is explained that information was gathered from structured interviews with principals, teachers, and 28 parents of language handicapped children, as well as visits to…

Discusses three studies: (1) the effectiveness of semantic analyses of written narratives of students with hearing losses in determining language ability; (2) written-language characteristics of writers matched by reading abilities alone and matched by reading ability and age; and (3) written-language characteristics of writers with hearing…

With the increasing number of Spanish-English bilingual children in the U.S., both SLPs and researchers must understand speech and language developments in these children--and SLPs also need reliable assessment and intervention approaches for serving bilingual children with language disorders. This comprehensive text is one of the few to offer…
