BackgroundResearch in education suggests that spatial ability may be a predictor of student success in spatially complex disciplines, including anatomy. Many anatomical structures and systems interact both functionally, and spatially within the human body, and as a result, mastery of anatomy requires a comprehensive understanding of these spatial relationships. Debate exists regarding the malleability of spatial ability, yet some researchers demonstrate that spatial ability can be enhanced through various training protocols, typically requiring long‐term experience. It is proposed that the ability of spatially low‐performing individuals can be trained in a brief period of time through visual guidance.MethodsTraining consisted of a visual guidance protocol based on the visual apprehension patterns of high spatial individuals during the completion of an electronic Mental Rotations Test (EMRT) based on the line drawings of Shepherd and Metzler. The effects of visual guidance were evaluated using 33 low spatial individuals, as classified by the Vandenberg and Kuse Mental Rotation test in a counterbalanced crossover design. (Mean score = 5.1 ± 1.9 (SD); Mean Age = 25.9± 5.0 yrs; n=33, 24F: 9M) Individuals in the treatment groups (Early, or Late Training) were exposed to both a guided electronic mental rotation test (EMRT) and an unguided EMRT, while control group participants completed the unguided EMRT twice.ResultsAll groups demonstrated an increase in EMRT scores on their second iteration of the test (F2, 30) = 28.29 (p<0.001); however an interaction was observed between treatment group and test iteration F(2, 30) = 4.22 (p = 0.024). The effect of visual guidance on EMRT scores was contingent on when the visual guidance was applied. When guidance was applied at the outset of training, the observed increase in scores were significantly greater than that expected based on repetition alone (Early Guidance: 6.91 ± 2.46 (95% CI) vs. Late Guidance: 2.82 ± 1.69 and No Guidance: 3.55 ± 1.43) (t(10) = 2.58, p = 0.028). Analysis of agreement in salience patterns revealed that Late Guidance agreed with exemplars in 22% of question (κ = 0.11) on the Unguided EMRT, and 37% on the Guided EMRT (κ =0.25). Early Guidance agreed with exemplars on 22% of questions (κ = 0.11) on the Unguided EMRT, and 44% on the Guided EMRT (κ =0.33). Controls agreed on 44% and 25% of questions (κ = 0.33 and 0.09) on both Unguided EMRTs.SummaryThe current findings suggest that by guiding low spatial individuals “where” to look during spatial problem solving at the outset of training, better search approaches may be adopted and improvements in overall spatial reasoning may be observed. It is proposed that visual guidance derived from eye tracking may be translated to improvements in spatially complex domains such as STEMM (Science, Technology, Engineering, Mathematics and Medicine), surgery, aeronautics and anatomy.Support or Funding InformationThis research was conducted with support from the Social Sciences and Humanities Research Council of Canada.
