      First Language Acquisition

       Anyone concerned with the study of human nature and human capacities must somehow come to grips with the fact that all normal humans acquire language, whereas acquisition of even its barest rudiments is quite beyond the capacities of an otherwise intelligent ape.

2.1 chapter overview

      The term “second language acquisition” suggests that a first language (L1) has already been acquired. Having a basic knowledge about L1 acquisition, an ability that is an essentially universal aspect of the general human condition, can be considered as fundamentally important in order to better understand second language (L2) acquisition. This chapter will begin by providing a basic description of L1 development and by presenting theoretical views proposed to explain the processes underlying that development. The second part of this chapter will present some of the dimensions along which L2 acquisition differs from or parallels the L1 acquisition process.

2.2 from sound to word

      Babies are born into the world unable to linguistically articulate specific desires, needs, feelings, or intentions. However, as anyone who has had any experience with infants realizes, babies do manage to communicate in very vocal and physical ways, through various forms and intensities of crying, cooing, other sounds, and by using physical movements and gestures. In the space of a few short months, such responses come to be gradually replaced by more language‐like sounds and by 12 months of age many children are already uttering their first words.

Considerable research has gone into examining the L1 acquisition process and much of this information reveals that infants appear to come into the world equipped to acquire the language they are exposed to in their environment. Linguists often use the term “prewired” to describe this state of readiness. In fact, many linguists argue that innate structures are the only reasonable explanation for the rapidity of development and universality of stages that characterize L1 acquisition. Noam Chomsky, the pre‐eminent linguist of our times, uses the analogy of a child “learning” to walk: the child does not need to be taught to walk, he or she simply begins to put one foot ahead of the other, as soon as the child is able to stand erect (Searchinger 1995). Similarly, acquiring the language used in one's environment unfolds in the same way: children do not need to be deliberately “taught” to speak, they simply begin to do so.

      Substantial evidence supports the idea of a genetic predisposition for language. For instance, a number of studies have shown that infants show a preference for the human voice, and in particular for the mother's voice, as young as three days old (DeCasper and Fifer 1980). The preferences of very young infants can be measured using a technique known as high amplitude sucking ( HAS ). In this technique, infants are exposed to sounds while their sucking rate on a pacifier is measured; an increase in rate is thought to indicate increased interest as well as the infant's detection of a stimulus difference. This technique therefore capitalizes on several facts: babies like to hear sounds; they lose interest when a sound is presented repeatedly; and they regain interest when a new sound is presented. The HAS technique is reliable from approximately one to four months of age.

      A technique used to study infant perceptual abilities; typically involves recording an infant's sucking rate as a measure of its attention to various stimuli.

      The HAS technique has revealed that newborns prefer speech sounds to non‐speech sounds (Vouloumanos and Werker 2007). Young infants also prefer looking at the human face, and prefer gazing at mouth movements that move in synchrony with the speech produced by those movements. The groundwork for conversational interaction is apparent in the early gaze‐coupling, or eye contact, behavior between the caregiver and the infant. Even at early pre‐verbal stages, interactional patterns characterize infant–caregiver communication; for example, infants wait for adult vocalizations in response to their own, and their sounds become more speech‐like following adult speech addressed to them.
