Abstract
Reading disability (RD) is a key obstacle in the development of literacy (Hanford, 2018; Wong, 2011; Torgesen, 2004). Studies show that 15-20% of grade-school students have RD, and that this has lifelong consequences for the individual and the wider community. Based on two experimental tasks (SCO and NSCM), the current study examines a key potential source of RD in young children (8-12 years old), namely that due to on deficits in phone-level perception. Our findings on RD phone perception loss is predictable, in our view, based on Harvey Fletcher’s venerable 1921 theory of speech perception (Allen, 2005b,a). The Syllable-Confusion Oddball (SCO) procedure is an unsupervised 3-interval forced- choice (3-IFC) closed-set task, to determine which of more than 20 phones have perceptual errors. The Nonsense Syllable Confusion Matrix (NSCM) procedure is a supervised one-interval open set task, where the subject hears one or more of 20 consonant vowels (CV), and orally reports back what he or she heard. SCO and NSCM complement each other, providing related information.
