    Response contrast, not just reduced auditory sensitivity, explains speech sound perception shifts after adaptation. This phenomenon influences how we perceive voiced and voiceless speech sounds.

    Area of Science:

    • Auditory Perception
    • Speech Processing
    • Psycholinguistics

    Background:

    • Auditory adaptation effects are typically explained by decreased sensitivity in auditory feature detectors.
    • An alternative hypothesis suggests response contrast influences speech sound identification.
    • Selective adaptation studies examine perceptual shifts following exposure to specific stimuli.

    Purpose of the Study:

    • To investigate the role of response contrast in speech sound identification after adaptation.
    • To differentiate between sensory adaptation and response contrast explanations for perceptual shifts.
    • To determine if adaptation effects are featural or phonemic.

    Main Methods:

    • Subjects identified synthetic consonant-vowel syllables near the voiced-voiceless boundary.

  • Contextual stimuli with varying voice onset time (VOT) were presented before or after test syllables.
  • Stimuli varied in place of articulation (bilabial vs. velar) to test featural vs. phonemic effects.

    • Main Results:

    • Exposure to a voiced stimulus ([b]) shifted identification towards voiceless ([ph]), and vice versa, demonstrating a contrast effect.
    • Contrast effects persisted even when contextual stimuli followed test items, ruling out single-trial sensory adaptation.
    • The effect occurred between stimuli with different places of articulation, suggesting a featural basis.

    Conclusions:

    • Response contrast significantly contributes to adaptation effects in speech sound perception.
    • Perceptual shifts are not solely due to reduced auditory feature detector sensitivity.
    • These findings highlight the importance of context in auditory perception and speech processing.
