520 $a Speech segmentation, the process of breaking continuous streams of sound into units that can be recognized, is a necessary element of auditory language processing. Previous research has shown that a number of semantic, syntactic, and acoustic cues can be used to segment speech under specific circumstances. However, few studies address the issue of which cues listeners actually do use when processing continuous speech. The first study included here addressed this issue by measuring the relative use of lexical, syntactic, and stress-pattern segmentation cues in the same behavioral paradigm. It was shown that native English speakers used all three of these types of cues in a flexible manner. The second study expanded these findings to include four groups of non-native speakers. Both age of acquisition and characteristics of the groups' native languages influenced which English-specific segmentation cues non-native speakers learned to use, indicating that different subsystems within language have different degrees of experience-dependent plasticity. The third study identified an event-related potential (ERP) index of speech segmentation, establishing an online measurement of the segmentation process and allowing for investigation of the cortical organization of speech segmentation systems. This ERP word-onset effect was not influenced by lexical and syntactic information. The fourth study explored the ERP word-onset effect in non-native speakers and found that even when late-learners of a language are able to use native segmentation cues, they do not do so in the same manner as native speakers. The fifth study further investigated the nature of the ERP word-onset effect by employing an artificial language. After training, listeners who learned the words of the language well showed both word-onset effects and ERPs indexing lexical search. Together, these five studies contribute to a better scientific understanding of language processing in general and speech segmentation, cortical plasticity of subsystems within language, and cortical organization of speech segmentation specifically.
