One of the most representative morpho-phonological features of Finnish is the existence of vowel harmony. Back vowels (a, o, and u) and front vowels (ä, ö, and y) cannot appear in the same monomorphemic word (e.g., PÖYTÄ [table] but not POYTÄ)--the vowels e and i are considered "neutral" and can accompany either front or back vowels…

Most orthographies contain both accented and non-accented vowels. But are they processed as variants of the same letter unit or as separate abstract units? Recent research in French has revealed that accented vowels seem to be processed as separate units. Here we examined whether this phenomenon is universal or language-specific. We chose Spanish…

An often overlooked but fundamental issue for any comprehensive model of visual-word recognition is the representation of diacritical vowels: Do diacritical and nondiacritical vowels share their abstract letter representations? Recent research suggests that the answer is "yes" in languages where diacritics indicate suprasegmental…

We examined whether the first letter advantage that has been reported in the Roman script disappears, or even reverses, depending on the characteristics of the orthography. We chose Thai because it has several "nonaligned" vowels that are written prior to the consonant but phonologically follow it in speech (e.g., ??? <e:fn> is…

It is unclear whether the association between the visual attention (VA) span and reading differs across languages. Here we studied this relationship in Arabic, where the use of specific reading strategies depends on the amount of diacritics on words: reading vowelized and nonvowelized Arabic scripts favor sublexical and lexical strategies,…

Recent research suggests that there is a processing distinction between consonants and vowels in visual-word recognition. Here we conjointly examine the time course of consonants and vowels in processes of letter identity and letter position assignment. Event related potentials (ERPs) were recorded while participants read words and pseudowords in…

Prior research has shown that the search function in the visual letter search task may reflect the regularities of the orthographic structure of a given script. In the present experiment, we examined whether the search function of letter detection was sensitive to consonant-vowel status of a pre-cued letter. Participants had to detect the…

To investigate the neural bases of consonant and vowel processing, event-related potentials (ERPs) were recorded while participants read words and pseudowords in a lexical decision task. The stimuli were displayed in three different conditions: (i) simultaneous presentation of all letters (baseline condition); (ii) presentation of all letters,…

Nonwords created by transposing two "adjacent" letters (i.e., transposed-letter (TL) nonwords like "jugde") are very effective at activating the lexical representation of their base words. This fact poses problems for most computational models of word recognition (e.g., the interactive-activation model and its extensions), which assume that exact…
