Visual word recognition and vowelization in Arabic: new evidence from lexical decision task performances

The effect of vowelization signs on the process of visual word recognition in Arabic was investigated among 41 native Arab skilled readers with age average of 30.66 ± 9.09. The participants performed a lexical decision task using three types of words and pseudowords; full, partial and non-vowelized. The results showed that for both words and pseudowords, response times were shorter and accuracy levels were higher for the non-vowelized condition compared to the other conditions of vowelization. The results reinforce the argument that automatic lexical processes during word recognition in Arabic orthography might be disturbed by supplementary information such as vowelization.
