IntroductionNeurophobia is the fear of neuroscience experienced by students who are learning and applying content. Although the cause remains unclear, neurophobia presents a major barrier to student success in neuroanatomy. A preliminary study suggested that individuals with low working memory capacity (WMC) benefit from using high‐contrast anatomical images when learning neuroanatomy. However, the reason for the improvement is unknown.AimThis study uses eye tracking technology to better understand how individuals of varying WMC and expertise study neuroanatomical images. We aim to: 1) assess differences in gaze patterns between students of high and low WMC when viewing high and low contrast brain slices and 2) compare novices and experts to uncover potential competency‐related differences.MethodsUndergraduate students with no prior anatomical education (n=120) and neuroanatomical experts were recruited. During an eye tracking session, participants were given 5 minutes to study twelve structures on digital images of 4 brain slices (either coronal or transverse slices in high or low contrast) and were then tested on their ability to identify the learned structures on similar low‐contrast images. This procedure was repeated such that all participants were exposed to a set of coronal/transverse and high/low contrast images in a randomized fashion. All participants’ eye tracking data and test accuracy were recorded. After testing, participants completed the Automated Operation Span Task (OSPAN) to quantify WMC.ResultsPreliminary results show that students with high WMC are more accurate in identifying neuroanatomical structures when compared to low WMC students [F(1, 32), p =.088]. Dwell time was a significant predicting factor for accuracy [r(32)=40, p =.02]. High WMC students fixated longer on neuroanatomical structures when compared to low WMC students [F(1, 32)=6.50, p =.02]. Data collection from expert participants is ongoing.Discussion/ConclusionOverall, these results offer a quantitative measure of how neuroanatomical information is viewed and learned to gain insight into neurophobia and influence future teaching practices in neuroanatomy.
