Measuring acoustic cue encoding and categorization during speech processing using the auditory N1 and P3 ERP components

Toscano, J. C., & McMurray, B. (2011, November). Paper presented at the 10th Auditory Perception, Cognition, and Action Meeting, Seattle WA.

Abstract: An important question in speech perception is whether listeners encode speech sounds in terms of continuous acoustic cues at early stages of processing or whether they perceive them only in terms of categories... Read more →

The role of phoneme order and phonetic detail in spoken word recognition

Toscano, J. C., Anderson, N. D., & McMurray, B. (2011, October). Paper presented at the 17th Mid-Continental Phonetics and Phonology Conference, Urbana, IL.

Abstract: 

A basic challenge in understanding spoken word recognition is that speech unfolds over time.  This has led to a great deal of work in psycholinguistics on how listeners deal with temporary  ambiguity (Allopenna, Magnuson, & Tanenhaus, 1998; Luce & Pisoni, 1998; Marslen-Wilson,  1987), demonstrating that during early time points in a word (when its identity is still  ambiguous), listeners consider multiple lexical candidates that compete for recognition...

Modeling age of exposure in L2 learning of vowel categories

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 →

Something old and something new

Word learning as the interaction of statistical association and dynamic competition

McMurray, B., Apfelbaum, K. S., Toscano, J. C., & Samuelson, L. K. (2010, March). Paper presented at the 2010 International Conference on Infant Studies, Baltimore, MD.

Abstract:

Research on word learning is riddled with meta-theoretical claims about the difficulty of the problem–the amount of ambiguity; the rate of acquisition; non-obvious or conceptual information sources—that point toward specialized mechanisms attuned for lexical development... Read more →
