Retinal areas used for reading and eye movements to completely uncover presented words
| Subjects | Areas used to decipher single letters and isolated words | Areas used to read paragraphed text | Ocular movements to entirely uncover presented words | ||||||

PRL: initial PRL; TRL: examiner's selected TRL; nPRL: additional newly self-selected PRLs. Following the training four subjects (SL, LG, AA, GM) used either the examiner's selected TRL and/or newly self-selected PRLs both for isolated words' deciphering and for paragraphed text reading. Note that, before training, only two subjects were able to perform eye movements to entirely uncover isolated words, either sequentially using the initial PRL, or at once using the examiner's selected TRL. Immediately following training, all subjects were able to achieve the task. In four out of five subjects this capacity was retained three months following SLO training. Note also that the subject that did not retain the ability to uncover words also did not retain any functional training gains.
