Although learning a second language can be difficult, especially for adults, many people believe that once an individual has acquired a second language, it will be easier to learn a third. Individuals may utilize strategies learned from studying a second language (L2) to their study of a third, but this does not necessarily mean that learning a third language (L3) will be easier. As individuals study an L3, their knowledge of both their native language (L1) and their L2 will compete with their developing knowledge of the L3. Previous research has shown that during early stages of L3 acquisition, both L1 and L2 phonology (that is, the underlying sound system of a language) influence the phonology of their L3. This is evident, for example, in learners’ production of some word-initial consonants, such as d, p, and k. Languages differ in the timing between the articulation of the consonant and the beginning of vibration of the vocal folds (voicing) associated with a following vowel sound. This timing is known as Voice Onset Time (VOT). Studies suggest a stronger influence from L2 than from L1 in L3 VOT production. However, learners in these studies had some (if limited) knowledge of the L3, and the influence of this knowledge is unclear. In addition, previous studies have addressed L3 production, but not L3 perception. Research has yet to investigate (i) the influence of L1 and L2 phonology in the very initial stages of L3 acquisition (when the language is totally unfamiliar), and (ii) the influence of L1 and L2 phonology on the perception of VOT boundaries. This study investigates (i) and (ii) by presenting English and Spanish bilinguals with stimuli representing a range of VOT in their L1 and L2, as well as from a third, unfamiliar language in a series of tasks designed to elicit evidence of VOT boundaries in each language. The results of these tasks will be examined to determine whether learners rely more on their L1 or their L2 for processing a third, unfamiliar language. Preliminary results and analyses will be available by February 2013. This research will give important insights into the process of acquisition of a third language.
