overgeneralization
The use of a rule or structure in contexts in which it is not appropriate; for example, “I hurted my arm.”
Further, young children begin by listening and speaking and only learn literacy‐related skills such as reading and writing (or descriptive grammar, as illustrated in the cartoon) once they reach school age. In fact, in some societies, literacy skills are never developed by a substantial proportion of the population, or only to a limited extent. Yet all children without significant cognitive disabilities learn to carry on fluent conversations in the language of their environment. In parallel, to a large extent it remains common for L2 learners to begin in a similar fashion, by engaging in listening and speaking skills before mastering reading and writing skills, although, as pointed out in the previous section, L2 learners can and do opt to use their literacy skills to learn the language. Traditionally, many teaching approaches reinforced this sequence, to the extent that some L2 methods almost banished written material from beginning language classrooms in the mid‐twentieth century.

2.6 summing up
This chapter has pointed out considerable evidence that innate structures offer a reasonable explanation for the rapidity of development and universality of stages that characterize L1 acquisition. Babbling occurs early on, and at approximately the first year mark, the child's first recognizable word may appear. At around the 50‐word vocabulary mark, children appear to begin to string two words together, and vocabulary and grammatical development accelerates thereafter. Children's grammatical development has been measured in terms of MLU, calculated in terms of morphemes per utterance. Brown (1973) found that children differ in rate of MLU development, although they acquire forms in a similar order. It has also been established that children tend to make typical errors, including overgeneralizing rules, as in using “mouses” instead of “mice.” They also may go through a period in which word meanings are overextended (“dog” for all four‐footed animals) and/or underextended (“dog” only for the family pet).
There are considerable differences in learning a first language as an infant and learning a second language after a first language has been acquired. Many of the differences are related to age and cognitive developmental factors. Others are related to the very fact that for L2 acquisition one language is already available to enable basic communication and the expression of needs and desires. On the other hand, despite these remarkable differences, there is much about the two processes that is similar: similar patterns of development, similar errors, similar strategies that mark developmental stages. As we continue to explore second language acquisition, an awareness of these differences and similarities should permit a better understanding of the challenges faced by the second language learner.

discussion questions
1 It is argued that children do not receive explicit correction when they use ungrammatical forms. Do you agree with this claim? Why or why not? Are there other ways in which children might get feedback or come to realize that their utterances are not grammatical?
2 To what extent do you think there are individual differences affecting children's acquisition of their first language? Based on your own personal experience, have you encountered any differences, such as with regard to rate of L1 acquisition, among children you know?
3 Do you know what was the first word or words that you produced? If so, СКАЧАТЬ
