This study aims to conceptually replicate the third experiment reported in the article “Proximity and precedence in arithmetic” (Landy & Goldstone, 2010). Specifically, we are interested in how the physical spacing between operands affects the calculation of mixed addition and multiplication expressions through the “Operation Precedence Task” in a forced-choice response format. We are also interested in a possible association between perceptual grouping biases and math skills, in terms of arithmetic fluency measured with another behavioral task (Math4Speed) and two self-report measures, i.e., educational level and school math performance.
