Lack of Implicit Prosody Effects in Deaf Readers of Japanese
AbstractProsodic contours have been claimed to be implicitly imposed on sentences read in silence, thereby affecting the interpretation of ambiguous constructions (the implicit prosody hypothesis, Fodor 2002). Some of the strongest evidence supporting this hypothesis manipulated the prosodic length of segments (Hirose 2003). However, such manipulations also increase the number of characters in the critical words, thus the results may not reflect the influence of prosodic factors but rather how perceptual mechanisms and working memory handle written words with larger numbers of characters. If so, such results should be replicable with readers who have low ability in handling prosodic information. We report experimental results suggesting that deaf readers are not sensitive to Hirose’s length manipulations. Therefore, the manipulations are likely to be related to prosodic contours rather than some other type of length measurement.
