title: How orthographic transparency affects morphological processing in young readers with and without reading disability.
abstract: This study investigates how orthographic modifications to the stems of complex words affect morphological processing in proficient young Spanish readers and children with reading deficits. In a definition task all children, irrespective of their reading skill, were worse at defining derived words that had an orthographic alteration of the base stem than words with no orthographic alteration. In a go/no-go lexical decision task, an interaction between base frequency and orthographic alteration was found: base frequency affected derived words with no orthographic alteration more than words with alterations, irrespective of reading skill. Overall, results show that all children benefit from a high frequency base, skilled children outperform children with reading deficits and morphological processing is affected by orthographic alterations similarly in proficient and impaired readers.
