Studies of listeners' ability to distinguish languages when segmental information is eliminated have been taken as evidence for categorical rhythmic distinctions between language groups ("rhythm classes"). Furthermore, it has been suggested that sensitivity to rhythm class is present at birth and that infants must establish the rhythm class of…

Introduction: The perception of syllable stress has not been widely studied in developmental dyslexia, despite strong evidence for auditory rhythmic perceptual difficulties. Here we investigate the hypothesis that perception of sound rise time is related to the perception of syllable stress in adults with developmental dyslexia. Methods: A…

Speakers employ acoustic cues (pitch accents) to indicate that a word is important, but may also use visual cues (beat gestures, head nods, eyebrow movements) for this purpose. Even though these acoustic and visual cues are related, the exact nature of this relationship is far from well understood. We investigate whether producing a visual beat…

Four experiments explored French-learning infants' ability to segment words from fluent speech. The focus was on bisyllabic words to investigate whether infants segment them as whole words or segment each syllable individually. No segmentation effects were found in 8-month-olds. Twelve-month-olds segmented individually both the final syllables…

Describes several experiments which examined the basic claims of metrical phonology. The first two experiments examined the possible influences of stress clash in speech timing. The third and fourth experiments tested Hayes's (1984) analysis rule of quadrisyllabic meter; the fifth experiment included a basic test of the stress clash notion. (SED)
