Interhemispheric interaction for all stimuli during word recognition in Arabic, Hebrew, and English. Panel A: Sensitivity scores (d') in the bilateral and unilateral conditions for native readers of Arabic, Hebrew, and English. * indicate that d' is significantly different from 0, such that participants were not responding at chance level. Error bars are standard errors. Panel B: bias scores, indexing response biases in errors. Positive number indicates misses (a bias to respond 'nonword' when the stimuli were really words) Negative scores indicate false positives (a bias to respond 'word' when the stimuli were nonwords). Error bars are standard errors.
