In contrast with visual perception, about which there is a larger body of knowledge, relatively little information exists concerning auditory perception and its relationship to reading. This fact is both surprising and troublesome as several researchers have found that auditory perceptual measures are better predictors of reading achievement than are visual perceptual measures (Blank, 1968; Linder & Fillmer, 1970; Muehl and Kremenak, 1966). It has been widely assumed that some basal level of auditory skill is related to normal language acquisition, school readiness, and academic achievement, particularly reading. Various auditory perceptual processes have been described, including the processes of discrimination, memory, synthesis (sound blending), and analysis (closure).
