Comprehension is often seen as the ultimate goal of reading instruction. In fact, the National Reading Panel wrote that "comprehension is critically important to development of children's reading skills and therefore their ability to obtain an education" (National Institute of Child Health and Human Development [NICHD], 2000, p. 4-1). However, it is important to understand that multiple distinct cognitive processes interact to create the construct we commonly refer to as reading comprehension.Perfetti, Landi, and Oakhill ( 2005) created a cognitive model of reading that recognizes the interactions between a written text, word identification, comprehension, and background knowledge. In a recent review, Savaiano, Compton, and Hatton (2014) used the Perfetti et al. (2005) model to frame existing Braille reading research. They highlighted that the majority of researchers of Braille reading have concentrated on word identification processes, specifically focusing on the perceptual features of the Braille code itself and the rate at which students can decode Braille.Although decoding is an integral part of the reading process, it is only helpful for comprehension if the resulting word is part of the reader's vocabulary (NICHD, 2000). The age of onset of blindness, visual diagnosis, and presence of additional disabilities are only a subset of factors that could potentially affect the quality and quantity of early learning experiences of Braille readers. There is a reciprocal relationship between vocabulary, comprehension, and amount of reading (Nagy, 598774E CXXXX10.
