Experimental: Reading Training
A 3-months study design. There will be three distinct phases: base-line testing, reading training, and follow-up testing. T1-T7 indicate the 7 time-points at which we assess the following: reading speeds (word-per-minute), visual field test, visual search test, and Activities of Daily Living rating scale (T1: Day 1, Initial assessments; T2: Day 30, Pre-training assessments; T3: Day 60, During Reading Training (RT) after 5-hours; T4: During RT after 10-hours; T5: During RT after 15-hours; T6: During RT after 20-hour; T7: Day 90, Post-training assessments). Arabic reading patients with left-sided HA will receive app-delivered reading training in a single subject control based design for 1 month.
Behavioral: Reading Training
Healthy subjects read moving (scrolling) text faster than static text. This type of text, also called "Times Square" presentation, induces a form of involuntary eye movement called optokinetic nystagmus (OKN) in the reader and, when used as part of a rehabilitation program, has been shown to improve subsequent reading performance of static text.
- Improvement of reading speed [ Time Frame: 1 month ]Average total reading time will be calculated in words per minute (wpm) using descriptive statistics in IBM SPSS.
- Patients will report improvement in static text reading (newspapers, books, letters, etc.) as a function of quality activity of daily living. [ Time Frame: 2 months ]Participants will rate themselves on their ability to perform activities of daily living (ADLs) as a measure of their functional status in regards to their reading impairment.
- Decrease in the number of fixations [ Time Frame: 1 month ]Fixation: maintaining visual gaze on a single location
- Decrease in average fixation durations [ Time Frame: 1 month ]Fixation duration: length of fixational pauses during reading
