Reading and spelling errors of vowels are reported in many studies (Bryson and Werker 1989; Fowler, Liberman, and Shankweiler
1977; Fowler, Shankweiler, and Liberman 1979; Goswami 1993; Landerl, Wimmer, and Frith 1997; Shankweiler and Liberman 1972).
The present study tested the hypothesis that spelling errors involving vowels are linked to difficulties in vowel perception.
Second to fourth graders (total n=155) were divided into five groups according to reading skill and were tested on a variety of measures involving vowel identification,
vowel discrimination, and vowel spelling. Despite little difficulty on the vowel discrimination tasks, participants made many
errors on the vowel identification measures. Vowel identification errors were linearly associated with reading skill with
least skilled readers having significantly more difficulty with stressed “short” vowels as in dip than with stressed “long” vowels as in deep, presented in identical contexts. Vowel identification errors were also associated with vowel spelling errors. It is hypothesized
that errors in vowel spelling may relate to weak access to the phoneme at the oral language level and may indicate a lack
of constancy in the representation of vowels by less skilled readers. Weaknesses in vowel perception can be detected with
a simple vowel identification test in which phonological similarity of test items is used as linguistic manipulation, and
where phonemes must be identified based on presentation of a single test item in a forced choice format. 相似文献

The purpose of this study was to identify pay disparities within gender and race using private and public Association of Research Libraries (ARL) libraries as a lens. In this study, 44 ARL libraries participated, leading to 1099 usable responses to our survey. The findings indicate that race and gender pay disparities are larger at private libraries than at public libraries. However, disparity levels at both public and private ARL libraries are smaller than the national averages for all professions and continue to shrink. 相似文献
