Learning irregular words involves mental marking of irregular letters in the spelling, a process not fully understood. In a within-subjects experiment, we manipulated the type of scaffolding given to beginning readers to evoke mental marking. We pretested to sort 103 kindergarten and first-grade participants into sequential decoders, who decode…

The study compared two versions of a computer program designed to increase sight-word reading vocabulary with nine reading disabled students, mean age 10 years 7 months. Although both versions were equally effective in improving speech and accuracy of reading words, the version requiring typing was more effective in increasing spelling accuracy.…

Nonwords created by transposing two "adjacent" letters (i.e., transposed-letter (TL) nonwords like "jugde") are very effective at activating the lexical representation of their base words. This fact poses problems for most computational models of word recognition (e.g., the interactive-activation model and its extensions), which assume that exact…

This study examined the validity and feasibility of a group-administered test of alphabetic reading skills for first-grade students. Two versions of a phonemic spelling test (production and multiple-choice) were administered in classroom groups to 153 students. Measures of vocabulary, phoneme awareness, letter sound knowledge, phonemic decoding,…
