Jeffrey Kramer Bye; Jenny Yun-Chen Chan; Avery H. Closser; Ji-Eun Lee; Stacy T. Shaw; Erin R. Ottmar – Journal of Numerical Cognition, 2024
Students often perform arithmetic using rigid problem-solving strategies that involve left-to-right-calculations. However, as students progress from arithmetic to algebra, entrenchment in rigid problem-solving strategies can negatively impact performance as students experience varied problem representations that sometimes conflict with the order…

Sawaya, Helen; McGonigle-Chalmers, Maggie; Kusel, Iain – International Journal of Developmental Disabilities, 2021
Objectives: The aim of the study is to distinguish between perceptuomotor and cognitive inflexibility as the source of set-switching difficulties in children with autism spectrum disorder (ASD). Methods: Seventeen adolescents with ASD and 17 neurotypical controls were presented with a computerized sequencing game using colored shapes. The sequence…

Ottmar, Erin; Landy, David – Journal of the Learning Sciences, 2017
Learning algebra is difficult for many students in part because of an emphasis on the memorization of abstract rules. Algebraic reasoners across expertise levels often rely on perceptual-motor strategies to make these rules meaningful and memorable. However, in many cases, rules are provided as patterns to be memorized verbally, with little overt…

Przysucha, Eryk P.; Maraj, Brian K. V. – Research Quarterly for Exercise and Sport, 2010
This investigation examined the catching coordination of 12 boys (M age = 9.9 years, SD = 0.8) with and without Developmental Coordination Disorder (DCD; M age = 10.5 years, SD = 0.8), under different task constraints. Participants attempted a total of 60 catches in central and lateral locations, under blocked and randomized conditions. No effect…

Clearfield, Melissa W.; Dineva, Evelina; Smith, Linda B.; Diedrich, Frederick J.; Thelen, Esther – Developmental Science, 2009
Skilled behavior requires a balance between previously successful behaviors and new behaviors appropriate to the present context. We describe a dynamic field model for understanding this balance in infant perseverative reaching. The model predictions are tested with regard to the interaction of two aspects of the typical perseverative reaching…
