Babai, Reuven; Nattiv, Laura; Stavy, Ruth – ZDM: The International Journal on Mathematics Education, 2016
Students' difficulties in mathematics and science may stem from interference of irrelevant salient variables. We focus on the comparison of perimeters task, in which area is the irrelevant salient variable. A previous fMRI brain-imaging study related to the comparison of perimeters task suggested that increasing the level of salience of the…

Babai, Reuven; Shalev, Enav; Stavy, Ruth – ZDM: The International Journal on Mathematics Education, 2015
Students' difficulties in mathematics and science may stem from interference of the task's salient irrelevant variables. Here, we focus on a comparison of perimeters task, in which the area is the irrelevant salient variable. In congruent trials (no interference), accuracy is higher and reaction time is shorter than in incongruent trials (area…
