abstract：:The Stroop test enables interference between color naming and reading to be studied. Protopapas et al. (2007) reported more errors in an interference task and longer reaction times in 12.5-year-old dyslexics; also more Stroop interference with lower reading skills. The present study uses a version of the Stroop with f...
