Foreign accents can vary considerably in the degree to which they deviate from the listener's native accent, but little is known about how the relationship between a speaker's accent and a listener's native language phonology mediates adaptation. Using an artificial accent methodology, we addressed this issue by constructing a set of three…

Language and accent strongly influence the formation of social groups. By five years of age, children already show strong social preferences for peers who speak their native language with a familiar accent (Kinzler, Shutts, DeJesus, & Spelke, 2009). However, little is known about the factors that modulate the strength and direction of…

This article shows that first language (L1) transfer may not be effectively maintained in the interlanguage due to confounding factors in the second language (L2). When two factors, "A" and "B," are correlated in the L2, second language learners may only acquire "B," even if "A" is present in the L1.…

This article examines the influence of gradient foreign accentedness on lexical competition during spoken word recognition. Using native and Mandarin-accented English words ranging in degree of foreign accentedness, we investigate the effect of increased accentedness on (a) the size of the competitor space and (b) the strength and duration of…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…
