Stages of speech development in the first year of life

Abstract

Publisher Summary This chapter discusses the stages of speech development in the first year of life. The development of speech-production skills in infants and young children occur in a sequence of stages, each one of which is related to its predecessors in a coherent way. The orderly progression has certain universal aspects. Individual differences are found within each stage of development and in the degree of overlap of behaviors deriving from one stage and those that are characteristic of its successors. However, the same progression is observed in all normal infants, and at a slower rate in many retarded children. The development of speech can be like the development of motor skills, in general, and of intelligence in the sensorimotor period. Throughout the sensorimotor period, the infant's ability to communicate evolves. The chapter describes the infant's developing speech-production skills in relation to his communicative use of these skills. The output of infants in the vocal-play stage and in other stages of vocal development is highly variable.
