Objective. As a basis for an application in anatomy education, vision‐based spatial abilities have been previously correlated with a drawing score based on haptic perception of objects. The objective of the current study was to determine whether a picture could replace a drawing in correlating haptic perception of objects with vision‐based spatial abilities tests. Methods. A cohort of 48 medical graduates was enrolled in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRTA) and three (MRTC) dimensions and a Surface Development Test (SDT). Twenty‐five objects constructed from various shaped parts glued together were identified on a picture by participants after haptic perception. The maximum score was 24 for each of MRTA and MRTC, 60 for SDT, and 25 for the picture score. Descriptive statistics included median and lower and upper quartiles. Spearman's correlation coefficient was used to compare the picture score to MRTA, MRTC and SDT scores. Results. The picture score [18 (12, 21)] was correlated with MRTA [14 (9, 17)], MRTC [9.5 (6.5, 12)] and SDT [44.5 (36, 53)] scores with a correlation of 0.427 (p = 0.0025), 0.539 (p < 0.0001) and 0.429 (p = 0.0024), respectively. Conclusions Vision‐based spatial abilities tests were correlated with pictures of objects recognized from haptic perception. Individual differences in spatial abilities as related to haptic perception have implications for education in the anatomy laboratory. This study was supported by an internal grant from the Department of Surgery, University of Sherbrooke, Sherbrooke, QC, Canada.
