This study investigates the role of phonological and morphological information in children's developing orthographies in two languages with different linguistic typologies: Hebrew, a Semitic language with a highly synthetic morphology, and Dutch, a Germanic language with a sparse morphology. 192 Israeli and 192 Belgian monolingual schoolchildren…

The present study assesses the phonological development of 17 children acquiring Finnish at the developmental point of 25 words (ages 1;2-2;0). The analysis is made using the "PHONOLOGICAL MEAN LENGTH OF UTTERANCE" (PMLU) method (Ingram & Ingram, 2001; Ingram, 2002), which focuses on the children's whole-word productions. Two…

The current paper reports of language production in 15 Hebrew-speaking boys, aged 9;0-13;0, with fully methylated, non-mosaic fragile X syndrome and no concomitant diagnosis of autism. Contrary to expectations, seven children were non-verbal. Language production in the verbal children was studied in free conversations and in context-bound speech.…

Fourteen Mother-Infant pairs were studied at three, six, and nine months to determine whether mothers simplify speech during the second half of the infant's first year and whether speech adjustment influences later language acquisition by infants. A mother's mean length of utterance (MLU) was predictive of later language development by her infant.…

The relationship between grammatical and lexical development was compared in 233 English and 233 Italian children aged between 1;6 and 2;6, matched for age, gender, and vocabulary size on the MacArthur Communicative Development Inventories (CDI). Four different measures of Mean Length of Utterance were applied to the three longest utterances…
