Influence of transparency and opacity on the spelling of fricative phonemes

Abstract Purpose (1) to verify what extent the occurrence of possible errors is influenced by relationship (opaque/transparent) between fricative phonemes and graphemes with which they can be spelled; (2) differences (if present or not) types among that common graphemic relationships. Methods We analyzed 750 textual productions from children in first year Elementary School (ES), conducted a survey frequency correct answers all Brazilian Portuguese (BP). Results The occurred greater numbers group opaque spelling when compared number transparent spelling. In group, showed non-symmetrical behavior, since varied according possibilities for each phoneme. second symmetrical behavior. Conclusion Given symmetry non-symmetry those our results point gradation errors, varies as function transparency degree opacity relations same class.
