Toscano, J. C. (2013, April). Invited paper presented at the Workshop on Current Issues and Methods in Speaker Adaptation, Ohio State University, Columbus, OH.
Abstract:
Recent work on perceptual adaptation has demonstrated that listeners can learn novel distributions of acoustic cues in unsupervised learning tasks with only a small amount of experience (Clayards, Tanenhaus, Aslin, & Jacobs, 2008, Cognition; Munson, 2011, dissertation)... Read more →
Toscano, J. C. (2013, February). Invited paper presented at the Department of Linguistics, University of Illinois at Urbana-Champaign.
Abstract: During language acquisition, one of the first tasks encountered by infants is determining which sounds indicate phonological distinctions in their language and which do not. This is a particularly challenging problem, since it requires unsupervised learning (i.e.,.. Read more →
Clayards, M. & Toscano, J. C. (2010, August). Poster presented at the 32nd Annual Conference of the Cognitive Science Society. Portland, OR.
Abstract: Age of exposure is known to be an important indicator of second language proficiency. Native-like phonological proficiency is attained only by learners exposed at the earliest ages. This paper examines one account of age-of-exposure effects... Read more →
Toscano, J. C., & McMurray, B. (2010). Cognitive Science, 34, 434-464.
Abstract: During speech perception, listeners make judgments about the phonological category of sounds by taking advantage of multiple acoustic cues for each phonological contrast. Perceptual experiments have shown that listeners weight these cues differently. How do listeners weight and combine acoustic cues to arrive at an overall estimate of the category for a speech sound?.. Read more →

Abstract: This chapter describes model of the development of simple analogical reasoning and shows how the model accounts for seven characteristics of children’s developing abilities to reason analogically... Read more →

Abstract: Recent evidence (Maye, Werker & Gerken, 2002) suggests that statistical learning may be an important mechanism for the acquisition of phonetic categories in the infant’s native language. We examined the sufficiency of this hypothesis and its implications for development by implementing a statistical learning mechanism in a computational model based on a mixture of Gaussians (MOG) architecture...
