简要总结
The purpose of the study is to evaluate the effectiveness of the combination of Rhythmic Reading Training (RRT), a computer-assisted intervention method that combines sublexical reading exercises with rhythm processing, and transcranial direct current stimulation (tDCS) on reading abilities of a group of Italian undergraduate students with dyslexia. Two experimental conditions (active vs. sham) will be compared. Finally, the effects of the intervention on other cognitive functions involved in the process of reading (i.e., rapid automatized naming, verbal working memory, rhythm perception abilities) will be measured.

结局指标
主要结局
Text reading speed expressed in syllables per seconds
时间窗: 2 weeks
The ability to read aloud a text was assessed using the Italian standardized test 'Prova di velocità di lettura di brani' (Zoccolotti, Fondazione S. Lucia), which provides speed and accuracy scores in reading aloud age-normed texts.

Word reading speed expressed in syllables per seconds
时间窗: 2 weeks
The ability to read aloud lists of words was assessed using the following Italian standardized tests: 'Assessment battery for Developmental Dyslexia and Dysorthography-2' (Batteria per la valutazione della dislessia e disortografia evolutiva - DDE-2), in which speed and accuracy scores were computed for word reading (4 lists of 28 words each with different lengths and frequency of use); 'Word and pseudo-word reading test' (WPRT, Prova di lettura di parole e non parole), in which speed and accuracy scores were computed for word reading (4 lists of 30 words varying according to length: short vs. long and frequency of use: low vs. high frequency).
