Seven Japanese dyslexic boys were evaluated as to their pedagogic performance on the pupil rating scale (PRS), and psychological and neurophysiological characteristics. One of them suffered from severe English dyslexia despite that his Japanese dyslexia was feeble. PRS did not successfully reveal their reading difficulties. Psychological examination (WISC-R and K-ABC) revealed their cognitive dysfunction, but the results were heterogeneous. The Token test was most useful for detecting their poor reading comprehension. Electroencephalogram (EEG) coherence analysis showed high inter- and intra-hemispheric values. These findings may imply hyperconnectivity of the cerebral white matter in dyslexia. We assumed that the Token test demonstrates the discrepancy between reading and hearing comprehension best of all among these psychological tests and that connectivity between non-functional cortical lesions remains in dyslexic children.
