Spatial Abilities and Pictures of Objects Recognized from Haptic Perception: Effect of Short Term Memory
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. The objective of the current study was to determine the effect of short term memory on the recognition of pictures of objects from haptic perception. The hypothesis is that the use of short term memory has a negative effect on the performance. 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 exercise, participants could touch the object for up to two minutes while identifying the corresponding picture. In the second exercise, 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 and upper quartiles. Spearman's correlation coefficient was used to correlate the picture score to MRTA, MRTC and SDT scores. Wilcoxon signed‐rank test was used to compare the picture score in the first and second exercise. Results The picture score in the first exercise [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. Similarly, the picture score in the second exercise [10 (7, 13)] was correlated with MRTA, MRTC, and SDT scores with a correlation of 0.444 (p = 0.0014), 0.384 (p = 0.0064) and 0.323 (p = 0.0236), respectively. The picture score in the first and second exercise was different (p < 0.0001). Conclusion Haptics is involved in the handling of anatomical structures. Vision‐based spatial abilities tests were correlated with pictures of objects recognized from haptic perception. The use of short term memory was found to have a negative effect on the performance. These findings on haptic perception and short term memory have promising avenues for education in the anatomy laboratory.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
