Soares, Lages, Oliveira, and Cabrera-Hernández (2019) recently showed that the mirror-letter interference effect observed for words containing reversal letters was reliable for words containing left-oriented mirror-letters as ‘d’, but not for words containing right-oriented mirror-letters as ‘b’, thus indicating that the directionality of the reversal letters cannot be disregarded when examining the cost of suppressing the mirror-generalization mechanism at the early stages of visual word recognition. Here we examined whether this bias can also be observed for left-oriented non-reversal letters such as ‘g’, ‘j’, and ‘z’, which just as ‘d’ are also prone to errors in writing in left-to-right orthographies as European Portuguese (EP). Thirty-six EP skilled readers performed a lexical decision task combined with a masked-priming paradigm in which target words containing either left-oriented (e.g., ‘g’, genial) or right-oriented (e.g., ‘c’, casual) non-reversal letters were preceded by 50 ms primes that could be the same as the target (genial–genial, casual–casual), nonword primes in which the critical letter was replaced by the mirror-image of the left- or right-oriented non-reversal letter (

Soares，Lages，Oliveira和Cabrera-Hernández（2019）最近表明，对包含反转字母的单词观察到的镜像字母干扰效应对于包含左向镜像字母为``d''的单词是可靠的，但对于包含右字母的单词则不可靠方向的镜像字母为'b'，因此表明在检查视觉单词识别早期阶段抑制镜像泛化机制的成本时，不能忽略反转字母的方向性。在这里，我们检查了是否也可以针对诸如“ g”，“ j”和“ z”之类的朝左的不可逆字母观察到这种偏差，就像“ d”一样，这些字母也容易产生从左到右的书写错误。右拼字法，称为欧洲葡萄牙语（EP）。
