Reports on six experiments examining the relationships between language processing in the Roman v the Cyrillic alphabets, both of which are used to read Serbo-Croatian. Notes some of the problems involved in operating with two separately used symbol systems. (Author/RL)

Three lexical decision experiments show that Serbo-Croatian letter-strings are ascribed two phonological readings simultaneously. This phonologic bivalence may impede lexical decision making if the letter-string has a lexical entry in one of the alphabets (Roman and Cyrillic). (RL)
