本研究的目的是考察影响单语和双语婴幼儿言语知觉发展的内在因素和外在因素。相当多的行为研究已经表征了婴儿对语音的行为随着对这些声音的经验量的变化而发生的变化。然而，这些研究无法解释语言经验对发育时间表的影响程度，而不是大脑皮质成熟对发育时间表的影响。使用电生理学方法来考察听觉和语音加工的发展的研究表明，婴儿和成人在加工的电生理相关上存在很大差异。这些差异中的许多是婴儿大脑皮质不成熟的功能。本文研究了婴幼儿事件相关电位(ERP)电生理成分在英语元音对比加工中的成熟度，并探讨了这些成分在多大程度上受内在因素(如性别)和外在因素(如语言经验(单语与双语)的影响。我们的研究结果表明，与年龄、性别和语言经验有关的事件相关电位反应模式存在差异。这些差异表明，在考察语言经验对言语知觉神经发育的影响时，需要考虑一般的成熟因素。
The goal of this paper was to examine intrinsic and extrinsic factors contributing to the development of speech perception in monolingual and bilingual infants and toddlers. A substantial number of behavioral studies have characterized when infants show changes in behavior towards speech sounds in relation to amount of experience with these sounds. However, these studies cannot explain to what extent the developmental timeline is influenced by experience with the language versus constraints imposed by cortical maturation. Studies using electrophysiological measures to examine the development of auditory and speech processing have shown great differences in infant and adult electrophysiological correlates of processing. Many of these differences are a function of immature cortex in the infant. In this paper, we examined the maturation of infant and child event-related-potential (ERP) electrophysiological components in processing an English vowel contrast and explored to what extent these components are influenced by intrinsic (e.g., sex) versus extrinsic factors, such as language experience (monolingual vs. bilingual). Our findings demonstrate differences in the pattern of ERP responses related to age and sex, as well as language experience. These differences make it clear that general maturational factors need to be taken into consideration in examining the effect of language experience on the neurodevelopment of speech perception.
