Perception of continuous acoustic cues in speech revealed by the auditory N1 and P3 ERP components

Toscano, J. C., & McMurray, B. (2012, October). Poster presented at the 2012 Neurobiology of Language Conference, San Sebastian, Spain.

Abstract: Many models of speech perception posit that listeners perceive speech sounds categorically (i.e., that the units of speech perception are phoneme categories), and behavioral and electrophysiological evidence has supported this... Read more →

Measuring perceptual encoding and categorization of speech sounds using an ERP approach

Toscano, J. C., & McMurray, B. (2012, January). Poster presented at the 6th Conference of the Auditory Cognitive Neuroscience Society, Tucson, AZ.


To recognize speech, listeners must map continuous acoustic features in the sound signal onto discrete units (e.g., phonemes, words). An important question is whether speech sounds are initially encoded in terms of continuous cues or whether listeners perceive them only in terms of categories... Read more →

Continuous perception and graded categorization: Electrophysiological evidence for a linear relationship between the acoustic signal and perceptual encoding of speech

Toscano, J. C., McMurray, B., Dennhardt, J., & Luck, S. J. (2010). Psychological Science, 21, 1532-1540.

Abstract: Speech sounds are highly variable, yet listeners readily extract information from them and transform continuous acoustic signals into meaningful categories during language comprehension. A central question is whether perceptual encoding captures acoustic detail in a one-to-one fashion or whether it is affected by phonological categories... Read more →

Measuring cue encoding and categorization

A classic question in speech perception concerns whether listeners are sensitive to the continuous acoustic features in the speech signal independently of phonological information. Recent work has shown that listeners can perceive within-category acoustic differences at the level of lexical representations. However, these responses also show effects of phonological categories. Thus, it is unclear whether there is an earlier stage of processing that is not influenced by category information...
