PAE (the difference between the ambiguous and unambiguous variant of the same word) was larger both for the globally and the locally switched alphabet. Additionally, the effect of the global switch was larger in the local switch condition (local by global switch interaction).

In addition to presenting phonologically ambiguous and phonologically unambiguous words in two alphabets, we manipulated sustained and transient language control. The goal was to investigate (for the first time) the language control in within-language alphabet switching.

By combining shared letters we created words with lexical reading in only one alphabet (pseudowords in the other alphabet). Such words are slower to recognize in their ambiguous form as compared to the unambiguous versions of the same words, aka PAE: Phonological Ambiguity Effect

Some of the letters are shared between alphabets, and some of the shared letters are phonologically ambiguous.

Serbian speakers are highly fluent in two alphabets - Cyrillic and Roman.
