Visuospatial skills are considered important attributes when learning anatomy and there is evidence suggesting that this ability can be improved with training techniques including drawing. The Mental Rotations Test (MRT) has been routinely used to assess visuospatial ability. This study aimed to introduce students to drawing as a learning strategy for anatomy. Undergraduate speech science anatomy students took part in a drawing tutorial (n = 92), completed an MRT test, pre- and post-tutorial tests, and surveys regarding their use and attitudes toward drawing as a study tool. The impact on their examination performance was then assessed. Regardless of MRT score or attitude to drawing, students who participated in the drawing tutorial demonstrated immediate improvement in post-tutorial test scores. Students in the drawing group performed better in most anatomy components of the examination, but the result did not reach statistical significance. There was only a positive correlation between MRT score and one type of anatomy question (non-image-based) and speech physics questions (r = 0.315, p = 0.002). The unexpected finding may relate to the MRT which assesses spatial rather than object visualization skills. Students who liked drawing also performed significantly better in word-based and speech physics questions. It is likely that the style of identification question did not require the mental manipulation ability assessed in the MRT. This study demonstrated that students with lower MRT scores are not outperformed in all aspects of anatomy assessment. The study highlights the importance of a more nuanced understanding of visuospatial skills required in anatomy.
