BACKGROUND Oral and genital ulcerations have been previously reported in 3 Navajo children diagnosed with severe combined immunodeficiency disease with T- and B-cell lymphopenia (T-B(-)-SCID). OBJECTIVE To evaluate the occurrence of oral and genital ulcerations in 12 Athabascan-speaking American Indians with a diagnosis of T-B(-)-SCID (SCIDA group) and to compare their occurrence in non-Athab...

This paper is a cross-linguistic examination of teachers’ perception of morphologically-mediated spelling patterns, compared with children’s actual spelling performance on these same patterns. The study was conducted on two languages differing greatly in their typologies: Hebrew and Dutch. The research design of this study consisted of two spelling tests, one for Hebrew and one for Dutch. Each ...

This study analyses the scaling and alignment of low and high intonational targets in the speech of 27 children - nine English-speaking, nine Catalan-speaking and nine Spanish-speaking - between the ages of two and six years. We compared the intonational patterns of words controlled for number of syllables and stress position in the child speech to the adult target speech provided by their moth...

Recently, researchers have been debating whether children exhibit a universal “noun bias” when learning a first language. The present study compares the proportions of nouns and verbs in the early vocabularies of 24 Englishand 24 Mandarin-speaking toddlers ( M age 5 20 months) and their mothers. Three different methods were used to measure the proportion of noun types, relative to verb types: c...

Here, we directly investigated this claim by evaluating whether Japanese children's transcoding performance when writing numbers to dictation (e.g., "twenty five" → 25) was less error prone than that of German-speaking childr...
