Perceptual complexity and form class cues in novel word extension tasks: how 4-year-old children interpret adjectives and count nouns.

Two experiments examined the role of perceptual complexity, object familiarity and form class cues on how children interpret novel adjectives and count nouns. Four-year-old children participated in a forced-choice match-to-target task in which an exemplar was named with a novel word and children were asked to choose another one that matched the exemplar in either shape or material In experiment 1, 56 children were provided with lexical form class cues suggestive of adjectives. The results of Experiment 1 showed that perceptual complexity and not object familiarity determined whether children made material or shape matches. In Experiment 2, 56 children were provided with lexical form class cues suggestive of count nouns. The results of Experiment 2 showed that neither perceptual complexity nor object familiarity affected children's selections in the matching task. When provided with lexical form class cues suggestive of a count noun, children selected shape matches. Thus the results suggest that the perceptual properties of the objects presented to children coupled with the particular lexical form class cue determine which features of objects children attend to when interpreting novel words.

Quantity of communicative behavior in children from birth to 30 months.

68 normal children were observed during play interaction with their mothers. Children's communicative acts were coded according to form and function, based on seven levels of communicative competence. Seven age groups, corresponding to the developmental predominance of each, were formed from birth to 30 mo. Each included equal numbers of girls and boys. Total number of communicative acts were determined for each child. Girls produced significantly more communicative output than boys. Verbal children produced significantly more output than preverbal children. There were no significant differences between preverbal groups or between verbal groups. The results are discussed relative to other research.

[Cochlear implants: state of knowledge, prospects, indications for implantation].

The authors present the development of totally deaf patients treatment program using cochlear implants. Based on leading Europeans Centers qualification basis and selection criteria are discussed for this method of treatment both for adults and children. Next given are indications for extracochlear and intracochlear implants. Summarizing, they evaluate possible results using the above implants and prospects for the development of this program in our country.

[Assessing and measuring language development in the child. The Reynell Scales in a Dutch language area].

This article deals with the recent adaptation of the Reynell Developmental Language Scales to the Dutch language. The existing language tests for the Dutch language are reviewed and the need to adapt a test for young children, measuring both receptive and expressive language development, is argued. The adaptation of the original Reynell Developmental Language Scales to the Dutch language is described. An extensive standardisation was carried out with 1,288 Dutch-speaking children, carefully selected geographically and according to socio-economic status. The psychodiagnostic results of the standardisation are discussed. As a result there are now norms for children between 2 and 5 years, both for receptive and expressive language development. The adaptation of the original Reynell Scales to Dutch functions under the new name RTOS (Reynell Taalontwikkelingsschalen).

Toward mastery of Italian morphology: a cross-sectional study.

The use of Italian morphology was examined in 34 children ranging in age from 2;6 to 5;0. By the age of 3;6-4;0, high percentages of use in obligatory contexts were seen for a number of grammatical morphemes. Children age 2;6-3;0 showed percentages of use that were somewhat lower than those seen for the older children. In this age range, singular forms were used with higher percentages in obligatory contexts than plural forms, for several different types of grammatical morphemes. Greater control over singular forms in these younger children was corroborated by data from a comprehension task. Even at the younger ages studied, use of grammatical morphemes did not seem influenced by whether phonological cues to agreement were present, or whether the grammatical morphemes were homonymous. Percentages for grammatical morphemes in the form of free-standing morphemes were somewhat lower than percentages for morphemes taking the form of inflections, suggesting that the obligatory nature of inflections in Italian may be a more influential factor than the amount of morphological information contained in a grammatical morpheme.

Phonological devices in poems by English and Italian children.

Poems were elicited from 133 English children between two and six and 171 Italian children between three and seven, using a similar technique, and the results were compared. Both groups produced large numbers of poems. There were great similarities and some differences. The majority of poems in both samples contained phonological devices (mostly rhyme and alliteration) and the proportion was higher (87%) in the Italian sample than in the English sample (59%). The proportion of poems that contained rhyme was close to 45% in each sample, with no consistent age difference in either sample. About one-third of Italian poems and just over a fifth of English poems contained alliteration. The frequency of alliteration declined with age in the English sample but not in the Italian sample. Possible reasons for the differences between the samples are considered. It is argued that the similarities are more important, and their theoretical implications are discussed.

Overextensions in comprehension and production revisited: preferential-looking in a study of dog, cat, and cow.

This study investigated overextensions in comprehension and production using a new method (the preferential-looking paradigm) in which children (N = 99, mean age (younger) = 1;9, mean age (older) = 2;3) were asked to find the referent that matched the label they were given. Both Real Referent (in which there was a match) and Anomalous (in which there was no match) trials were included, as well as nonverbal control trials. During the Real Referent trials, all children significantly preferred the matching puppet. During the Anomalous trials, children showed no preference with two of the labels (dog and cat); however, they did show a preference when 'cow' was requested but not available. There were no differences based on prior overextension performance in production. It is concluded that overextensions in production are not diagnostic of children's underlying semantic representations, and that anomalous trials in comprehension provide useful information concerning young children's lexical entries.

Acquisition of derived nominals in Hebrew: developmental and linguistic principles.

Derived nominals are abstract nouns derived from verbs and adjectives by nominalization. This study traces the route taken by Hebrew-speaking children in the acquisition of Hebrew derived nominals (HDNs) of two types: action nominals which conform in structure to the small set of obligatory verb patterns (binyanim) (e.g., ktiva 'writing') and deverbal nouns, which belong to separate nominal patterns (e.g. maga 'touch'). One hundred native speakers of Hebrew (children aged 5, 8, 11 and 15, and adults) were tested on comprehension and production of HDNs. The test items were grouped by binyan patterns and by morphological regularity. Results showed that acquisition of HDNs starts at about age 8 and is not complete by age 15, and that task type, binyan pattern and morphological regularity all affect ease of acquisition. We consider the strategies employed in the course of acquisition of HDNs and offer an explanation for this late acquisition which requires a vast amount of prior integrated knowledge.

Perceptual discriminability and communication performance in preschool children.

The ability of preschool children to discriminate perceptually among novel forms frequently employed in referential communication tasks is examined. Results suggest that preschool children who are able to discriminate among the forms nevertheless perform poorly on a referential communication task involving these same forms. Asking children to provide names for the forms enhanced their discrimination performance but not their communication performance.
