Answer to Question 1
A specific defect in the perception of visual motion may interfere with many different brain functions, and it has been noted among children with autism as well as those with learning disorders (Benassi et al., 2010; Skottun & Skoyles, 2008). To detect differences between consonant soundssuch as b and twe must be able to distinguish between very rapid changes in sound frequency. A subtle neurological deficit in sensitivity could prohibit this distinction, which would then show up clinically as problems in reading and phonological processing (Raschle et al., 2011).
Answer to Question 2
Poor reading comprehension and poor spelling and written work. They may be able to read and pronounce the first part of a word correctly but then guess the rest of the word. As they struggle with these difficulties throughout elementary school, being fearful of or refusing to read aloud is common. By adolescence through to adulthood, these patterns often shift from basic coding difficulties to marked problems in reading comprehension and written expression, including poor spelling and poor mathematical problem solving. Over time, teens and adults learn to manage these difficulties to the best of their ability, but may avoid situations that require reading, writing, or numerical ability. Thus, over the life span SLD is associated with many functional consequences, such as lower academic achievement, higher school dropout rates, poor overall mental health and well-being, and lower employment and income (APA, 2013).
