The unique link between naming speed and word reading partly depends on using alphanumeric stimuli; non-alphanumeric naming speed adds no unique prediction¶

q3 i? When RAN digits and letters were added to the naming speed factor, a significant path from naming speed to word reading emerged (standardized loading = .23, p < .01). → Christopher 2012

Alternative SEM identical to the main model but with RAN digits and RAN letters loaded onto the naming speed factor. The article reports "the inclusion of naming digits and letters produced a significant path from naming speed to word reading (standardized loading = .23, p < .01)."

"Importantly the inclusion of naming digits and letters produced a significant path from naming speed to word reading (standardized loading = .23, p < .01)."

• Working memory and processing speed, but not inhibition or non-alphanumeric naming speed, uniquely predict both word reading and reading comprehension in children ages 8 to 16 — related
• Speed of numeral processing showed a trend predicting fifth grade mathematics achievement, and letter processing speed predicted word reading — related
• RAN stimulus type (numeric vs. non-numeric; alphanumeric vs. non-alphanumeric) largely does not moderate the RAN–mathematics correlation — related
