Xu, Chang; LeFevre, Jo-Anne; Skwarchuk, Sheri-Lynn; Di Lonardo Burr, Sabrina; Lafay, Anne; Wylie, Judith; Osana, Helena P.; Douglas, Heather; Maloney, Erin A.; Simms, Victoria – Developmental Psychology, 2021
In the present research, we provide empirical evidence for the process of symbolic integration of number associations, focusing on the development of simple addition (e.g., 5 + 3 = 8), subtraction (e.g., 5 - 3 = 2), and multiplication (e.g., 5 × 3 = 15). Canadian children were assessed twice, in Grade 2 and Grade 3 (N = 244; 55% girls). All…

Robinson, Katherine M.; LeFevre, Jo-Anne – Educational Studies in Mathematics, 2012
Researchers have speculated that children find it more difficult to acquire conceptual understanding of the inverse relation between multiplication and division than that between addition and subtraction. We reviewed research on children and adults' use of shortcut procedures that make use of the inverse relation on two kinds of problems:…

LeFevre, Jo-Anne – Mathematical Cognition, 1998
Presents a study in which 32 Chinese-speaking adults solved single-digit multiplication problems. Chinese adults made more errors that indicated interactions between phonological codes activated at encoding and production of answers as compared to samples of English, French, and Dutch-speaking adults from other studies. Contains 26 references.…

LeFevre, Jo-Anne; Liu, Jing – Mathematical Cognition, 1997
Examines adults from China and Canada solving single-digit multiplication problems. Reports that Chinese adults were faster and made fewer errors than Canadian adults, and Chinese adults made more errors that reflect verbal-production processes that may occur after retrieval whereas Canadian adults made more errors that reflect retrieval…
