Fast and slow readers of the Hebrew language show divergence in brain response ∼200 ms post stimulus: an ERP study.

Higher N170 amplitudes to words and to faces were recently reported for faster readers of German. Since the shallow German orthography allows phonological recoding of single letters, the reported speed advantages might have their origin in especially well-developed visual processing skills of faster...
