Erbeli, Florina; Hart, Sara A.; Wagner, Richard K.; Taylor, Jeanette – Scientific Studies of Reading, 2018
A fairly recent definition of reading disability (RD) is that in the form of a hybrid model. The model views RD as a latent construct that is manifested through various observable unexpected impairments in reading-related skills and through inadequate response to intervention. The current report evaluated this new conceptualization of RD from an…
