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. We addressed this(More)
In the absence of family history or overt chorea, the protean manifestations (cognitive, motor and behavioral) of Huntington disease (HD) may suggest alternative disease processes, particularly in elderly patients. Herein, we report on a nonagenarian with HD who did not manifest overt chorea until 91 years of age and was mistakenly diagnosed with normal(More)
A critical issue in perception is the manner in which top-down expectancies guide lower-level perceptual processes. In speech, a common paradigm is to construct continua ranging between two phonetic endpoints and to determine how higher level lexical context influences the perceived boundary. We applied this approach to music, presenting subjects with(More)
