[The related factors influencing development of language understanding and expression of early-children].

OBJECTIVE: To assess the level of language understanding and expression of healthy children aged from 8 to 16 months in urban Beijing and to investigate the children's physical and psychological development conditions and social and economic status of children's family as to identifying the related factors to children's language development and providing a basis for instructing parents child-rearing and promoting early children language development. METHODS: A quantitative Cross-sectional Study was made. The parents or care givers of 636 healthy young children, randomly stratified and selected in two districts in Beijing were interviewed. T-test was used to compare the scores of language understanding and expression between boys and girls in the same age. Single and multiple factors analysis were used so as to find out the related factors. RESULTS: For boys, the average scores of language were respectively 115.0 for 8 months, 243.0 for 12 months and 410.6 for 16 months; for girls the average scores were respectively 109.9 for 8 months, 286.4 for 12 months and 456.2 for 16 months. The average score of language understanding of boys was higher than that of girls only in the 11 month group. The average scores of language expression of girls were higher than those of boys in 11, 12, 14, 15 month groups. Multiple factors analysis showed that parent-child book reading, parent-child tape listening, higher education level of grandmothers, children' extroversion personality, child being able to speak one word and children's age were positively related to the children' language score. CONCLUSION: Providing rich language environment should be helpful to early children's language development.

Motor cortex hand area and speech: implications for the development of language.

Recently a growing body of evidence has suggested that a functional link exists between the hand motor area of the language dominant hemisphere and the regions subserving language processing. We examined the excitability of the hand motor area and the leg motor area during reading aloud and during non-verbal oral movements using transcranial magnetic stimulation (TMS). During reading aloud, but not before or afterwards, excitability was increased in the hand motor area of the dominant hemisphere. This reading effect was found to be independent of the duration of speech. No such effect could be found in the contralateral hemisphere. The excitability of the leg area of the motor cortex remained unchanged during reading aloud. The excitability during non-verbal oral movements was slightly increased in both hemispheres. Our results are consistent with previous findings and may indicate a specific functional connection between the hand motor area and the cortical language network.

Acquisition, learning, or development of language? Skinner's "Verbal Behavior" revisited.

In 1957, Skinner, in his "Verbal Behavior", proposed an explanation on how a language is learned. In 1959, Chomsky strongly argued the non-learnability of language, establishing in the field of developmental psycholinguistics the substitution of the term "learning" for that of "acquisition". Currently, the constructivist models describe language acquisition as a process of ontogenetic, gradual, complex, and adaptive change. This new theoretical framework has been especially useful for rereading Verbal Behavior because it facilitates recovering the Skinnerian learning mechanisms. This can be observed in the recent research trends that recapture reinforcement and imitation (echoic responses), although they are now located in the initial phases of the process and are included in a cognitive dynamic that, by gradually increasing its complexity, can achieve grammar. The new constructivist theoretical framework, by retrieving the functional and referential aspects of language, can also take advantage of the classic Skinnerian proposal about the pragmatic types of verbal behavior, providing it with new meaning.

A Swedish non-word repetition test for preschool children.

A Swedish non-word repetition test for preschool children was constructed with the aim of measuring short-term phonological memory, which has been shown to correlate with language development and language proficiency. Normative data based on results for 200 children four to six years of age are presented. An item analysis of the original 30-item test resulted in a shortened 24 non-word version found suitable for four- to six-year old children. Results for this shortened version, which had a Cronbach's alpha of 0.73, showed longer non-words to be more difficult to repeat than shorter ones, and significant effects of age and compatibility of the tester's and the child's accent, but not of gender. The results are discussed within the framework of Baddeley's working memory model.

Hearing and the development of language and speech.

The criticality of hearing is discussed in relation to language and speech development in children. The fundamentals for such development, the significant milestones in normal language and speech acquisition, and a delineation of the deleterious effects of significant hearing loss on the development of expressive and receptive oral communication are presented.
