The Effect of Age and Reading Level on Perceptual Weighting Strategy
Transition and vocalic roundness is known to affect perception of the
preceding fricative. The relevance of these factors were found to differ
in adults and children, by Nittrouer et al (1997). We replicated part
of this paradigm, and noticed that
- French adults and 1st graders
differed, but not in the use of the same cues as English speakers in
Nittrouer et al's paper. We observed a developmental increase of
the transition effect, and a developmental decrease in the effect of
the vowel identity on the identification of the preceding fricative.
- We reproduced the dyslexics' well known categorical deficit, and
observed that they weighted more the vowel than the transition to identify
the preceding fricative, as did younger reading controls.
