Limited Knowledge of Fraction Representations Differentiates Middle School Students with Mathematics Learning Disability (Dyscalculia) versus Low Mathematics Achievement
Peer reviewed Peer reviewed

Mazzocco, Michele M. M.; Myers, Gwen F.; Lewis, Katherine E.; Hanich, Laurie B.; Murphy, Melissa M. – Journal of Experimental Child Psychology, 2013
Fractions pose significant challenges for many children, but for some children those challenges persist into high school. Here we administered a fractions magnitude comparison test to 122 children, from Grades 4 to 8, to test whether their knowledge of fractions typically learned early in the sequence of formal math instruction (e.g., fractions…

Competence with Fractions Predicts Gains in Mathematics Achievement
Peer reviewed Peer reviewed

Bailey, Drew H.; Hoard, Mary K.; Nugent, Lara; Geary, David C. – Journal of Experimental Child Psychology, 2012
Competence with fractions predicts later mathematics achievement, but the codevelopmental pattern between fractions knowledge and mathematics achievement is not well understood. We assessed this codevelopment through examination of the cross-lagged relation between a measure of conceptual knowledge of fractions and mathematics achievement in sixth…

The Role of Form and Meaning in the Processing of Written Morphology: A Priming Study in French Developing Readers
Peer reviewed Peer reviewed
Direct linkDirect link
Quemart, Pauline; Casalis, Severine; Cole, Pascale – Journal of Experimental Child Psychology, 2011
Three visual priming experiments using three different prime durations (60 ms in Experiment 1, 250 ms in Experiment 2, and 800 ms in Experiment 3) were conducted to examine which properties of morphemes (form and/or meaning) drive developing readers' processing of written morphology. French third, fifth, and seventh graders and adults (the latter…

Lemaire, Patrick; Callies, Sophie – Journal of Experimental Child Psychology, 2009
Strategies used to solve two-digit addition problems (e.g., 27 + 48, Experiment 1) and two-digit subtraction problems (e.g., 73 - 59, Experiment 2) were investigated in adults and in children from Grades 3, 5, and 7. Participants were tested in choice and no-choice conditions. Results showed that (a) participants used the full decomposition…

The Developmental Turnpoint of Orthographic Consistency Effects in Speech Recognition
Peer reviewed Peer reviewed

Ventura, Paulo; Kolinsky, Regine; Pattamadilok, Chotiga; Morais, Jose – Journal of Experimental Child Psychology, 2008
The influence of orthography on children's online auditory word recognition was studied from the end of Grade 4 to the end of Grade 9 by examining the orthographic consistency effect in auditory lexical decision. Fourth-graders showed evidence of a widespread influence of orthography in their spoken word recognition system; words with rimes that…

Robinson, Katherine M.; Arbuthnott, Katherine D.; Rose, Danica; McCarron, Michelle C.; Globa, Carin A.; Phonexay, Sylvia D. – Journal of Experimental Child Psychology, 2006
Age-related changes in children's performance on simple division problems (e.g., 6 divided by 2, 72 divided by 9) were investigated by asking children in Grades 4 through 7 to solve 32 simple division problems. Differences in performance were found across grade, with younger children performing more slowly and less accurately than older children.…
