Spatial Abilities and Effect of Working Memory on Pictures of Objects Recognized from Haptic Perception
Notice bibliographique
Résumé
Objective As a basis for an application in anatomy education, vision‐based spatial abilities tests have been correlated with pictures of objects recognized from haptic perception. Decreasing haptic perception while increasing working memory has been found to decrease performance on pictures of objects recognized from haptic perception. The objective of the current study was to correlate spatial abilities to the effect of working memory on pictures of objects recognized from haptic perception. Methods A cohort of 48 medical graduates was enrolled in a prospective study. Ethics committee approval and written informed concent were obtained. 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). In a one‐month rotation preparing for residency, the experiment was done within a one‐week drawing course before a one‐week applied anatomy course. Twenty‐five objects constructed from various shaped parts glued together were identified on a picture by participants after haptic perception. In the first exercice, participants could touch the object for up to two minutes while identifying the corresponding picture. In the second exercice, 30 seconds were allowed for haptic perception of the object, 15 seconds to memorize, and up to 75 seconds to identify the corresponding picture without any further haptic access to the object. 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 (Q1) and upper (Q3) quartiles. Spearman's correlation coefficient (and associated p‐value) was used to correlate the picture score to MRTA, MRTC and SDT scores. Results Correlations of change in picture score between the first and second exercice [6.5 (3, 10)] with MRTA [14 (9, 17)], MRTC [9.5 (6.5, 12)] and SDT [44.5 (36, 53)] scores were −0.046 (p = 0.7577), 0.126 (p = 0.3945) and 0.149 (p = 0.3133), respectively. Conclusion Haptics is involved in the handling of anatomical structures. Spatial abilities tests were not correlated to the effect of working memory on pictures of objects recognized from haptic perception. Spatial abilities tests have been correlated to the effect of working memory on drawings of objects from haptic perception. These findings may be explained by the 2‐D nature of picture recognition and 3‐D nature of making a perspective drawing of an object.
