| Abstract: | The contributions of naming speed measured on both serial-list and various discrete-trial formats to several reading subskills were examined longitudinally to determine their impact independent of other reading-related skills on reading disabilities. Tests of symbol naming speed, phonological awareness, vocabulary, memory span and coding speed were given to 38 poor and average readers when they were in Grades 2, 3 and 4. Grade 4 poor readers were discriminated from moderately poor or good readers on serial-list and discrete-trial naming speed tests in all grades. In addition, phonological awareness and vocabulary, but not memory span or coding speed, discriminated groups. These variables in Grade 2 contributed unique variance to reading scores in Grade 4 in differing patterns. Hypotheses about the nature of the reading — naming speed relationship are discussed. |
