Toward an ERP-Driven Diagnostic Approach for Reading Impairments
ABSTRACT This preliminary study attempted to use Event Related Brain Potentials (ERPs) to identify different causes for slow reading performance. At least two unique brain activity patterns were found for below average readers. Based on visual inspection of the N170 ERP component elicited by words in a lexical decision task, participants were either classified as N170-normal or N170-absent. Although both groups showed very dissimilar brain activity patterns, they did not differ in any reading or cognitive measures. Differences in brain activity were discussed as indicators for disturbances at specific stages of word processing, which should lead to individually adjusted intervention approaches.

ABSTRACT: Working memory (WM) plays a crucial role in supporting learning, including reading. This study investigated the influence of reading acceleration and WM training programs on improving reading skills and WM abilities. Ninety-seven children in third grade were divided into three study groups and one control group. The three study groups each received a different combination of two training programs: only reading acceleration, WM followed by reading acceleration, and reading acceleration followed by WM. All training programs significantly improved reading skills and WM abilities. Compared with the control group, the group trained with only the reading acceleration program improved word accuracy, whereas the groups trained with a combination of reading and WM programs improved word and pseudo-word fluency. The reading-acceleration-alone group and the WM-program-followed-by-reading-acceleration group improved phonological complex memory. We conclude that a training program that combines a long reading acceleration program and a short WM program is the most effective for improving the abilities most related to scholastic achievement.Child Neuropsychology 12/2013; DOI:10.1080/09297049.2013.863272 · 2.18 Impact Factor
