Mental imagery rotation and graph comprehension of IS-LM macroeconomic models. PsyCh Journal, 10(6), 851–857http://hdl.handle.net/10347/27432The aim of this study was to determine if the ability to rotate mental imagery influenced the comprehension of graphs in economics. A sample of 140 Business Administration undergraduates familiar with economic analysis using graphs were administered the Measure of the Ability to Rotate Mental Images (MARMI). Moreover, participants completed an ad hoc graph comprehension test consisting of six exercises of increasing difficulty with graphs developing the IS-LM model described in conventional macroeconomic textbooks. Both the ability to rotate mental imagery and graph complexity (the number of quadrants in each graph) were found to significantly influence the number of correct graph comprehension responseseng© 2021 The Authors.
