  2. Toward a dual-learning systems model of speech category learning.Bharath Chandrasekaran, Seth R. Koslov & W. T. Maddox - 2014 - Frontiers in Psychology 5:88645.
    More than two decades of work in vision posits the existence of dual-learning systems of category learning. The reflective system uses working memory to develop and test rules for classifying in an explicit fashion, while the reflexive system operates by implicitly associating perception with actions that lead to reinforcement. Dual-learning systems models hypothesize that in learning natural categories, learners initially use the reflective system and, with practice, transfer control to the reflexive system. The role of reflective and reflexive systems in (...)

    Cortical Tracking of the Speech Envelope in Logopenic Variant Primary Progressive Aphasia.Heather R. Dial, G. Nike Gnanateja, Rachel S. Tessmer, Maria Luisa Gorno-Tempini, Bharath Chandrasekaran & Maya L. Henry - 2021 - Frontiers in Human Neuroscience 14.
    Logopenic variant primary progressive aphasia is a neurodegenerative language disorder primarily characterized by impaired phonological processing. Sentence repetition and comprehension deficits are observed in lvPPA and linked to impaired phonological working memory, but recent evidence also implicates impaired speech perception. Currently, neural encoding of the speech envelope, which forms the scaffolding for perception, is not clearly understood in lvPPA. We leveraged recent analytical advances in electrophysiology to examine speech envelope encoding in lvPPA. We assessed cortical tracking of the speech envelope (...)

    Language experience during the sensitive period narrows infants’ sensory encoding of lexical tones—Music intervention reverses it.Tian Christina Zhao, Fernando Llanos, Bharath Chandrasekaran & Patricia K. Kuhl - 2022 - Frontiers in Human Neuroscience 16.
    The sensitive period for phonetic learning, evidenced by improved native speech processing and declined non-native speech processing, represents an early milestone in language acquisition. We examined the extent that sensory encoding of speech is altered by experience during this period by testing two hypotheses: early sensory encoding of non-native speech declines as infants gain native-language experience, and music intervention reverses this decline. We longitudinally measured the frequency-following response, a robust indicator of early sensory encoding along the auditory pathway, to a (...)
