“…In addition, these are obtrusive and may interfere with a surgeon's primary tasks in the operating room. Finally, a series of secondary task studies assessed surgeons' cognitive load associated with training modality, surgical technique, task complexity, expertise and dexterity metrics. However, the secondary task can also be a distraction from the primary task, making it unreasonable to assess surgeons' cognitive load in the operating theatre.…”

Self-report instruments are valuable when the aim is to assess the overall cognitive load in different surgical procedures and assess learning curves within competence-based surgical education. When the aim is to assess cognitive load related to specific operative stages, real-time tools should be used, as they allow capture of cognitive load fluctuation. A combination of both subjective and objective methods might provide optimal measurement of surgeons' cognition.

“…Both CT and MRI have provided a large volume of cross‐sectional images which could be transformed into 3D images of anatomical structures by reconstruction techniques (Ghosh, ). The radiological image datasets have enriched anatomy education by providing computer simulation of the live human body, thus shifting the focus from traditional dissection based cadaveric anatomy to virtual reality (VR) techniques for anatomy learning (Albanese, ; Andersen et al, ). VR enables 3D projection of color images on the surface of human body, which can now be dissected layer by layer by the use of color transverse sections prepared with cross‐sectional image datasets (Temkin et al, ).…”

“…In another study students have reported that textbook reading and working with anatomical models were most important in helping them learn the course material and such an observation supports the role of active learning in gross anatomy alongside dissection‐based teaching (Shaffer, ). Researchers have noted that virtual reality (VR) simulation could be critical in developing basic competencies in anatomy among students (Trelease and Nieder, ; Küçük et al, ) However VR needs to be followed up by dissection based teaching to supplement and optimize skills training (Andersen et al, ).…”

Anatomical education has been undergoing reforms in line with the demands of medical profession. The aim of the present study is to assess the impact of a traditional method like cadaveric dissection in teaching/learning anatomy at present times when medical schools are inclining towards student-centered, integrated, clinical application models. The article undertakes a review of literature and analyzes the observations made therein reflecting on the relevance of cadaveric dissection in anatomical education of 21st century. Despite the advent of modern technology and evolved teaching methods, dissection continues to remain a cornerstone of anatomy curriculum. Medical professionals of all levels believe that dissection enables learning anatomy with relevant clinical correlates. Moreover dissection helps to build discipline independent skills which are essential requirements of modern health care setup. It has been supplemented by other teaching/learning methods due to limited availability of cadavers in some countries. However, in the developing world due to good access to cadavers, dissection based teaching is central to anatomy education till date. Its utility is also reflected in the perception of students who are of the opinion that dissection provides them with a foundation critical to development of clinical skills. Researchers have even suggested that time has come to reinstate dissection as the core method of teaching gross anatomy to ensure safe medical practice. Nevertheless, as dissection alone cannot provide uniform learning experience hence needs to be complemented with other innovative learning methods in the future education model of anatomy.

Context Three‐dimensional (3‐D) visualisation in anatomical education has been shown to be broadly beneficial for students. However, there is limited research on the relative efficacy of 3‐D modalities. This study compares knowledge performance, mental effort and instructional efficiency between autostereoscopic 3‐D visualisation (holograms), monoscopic 3‐D visualisation (3‐DPDFs) and a control (2‐D printed images). Methods A cardiac anatomy model was used to generate holograms, 3‐DPDFs and 2‐D printed images. Nursing student participants (n = 179) were randomised into three groups: holograms (n = 60), 3‐DPDFs (n = 60) and printed images (n = 59). Participants completed a pre‐test followed by a self‐study period using the anatomical visualisation. Afterwards, participants completed the NASA‐Task Load Index (NASA‐TLX) cognitive load instrument and a knowledge post‐test. Results Post‐test results showed participants studying with holograms (median = 80.0, interquartile range [IQR] = 66.7–86.7) performed significantly better regarding cardiac anatomy knowledge than participants using 3‐DPDF (median = 66.7, IQR = 53.3–80.0, p = 0.008) or printed images (median = 66.7, IQR = 53.3–80.0, p = 0.007). Mental effort scores, on a scale from 1 to 20, showed hologram (mean = 4.9, standard deviation [SD] = 3.56) and 3‐DPDF participants (mean = 4.9, SD = 3.79) reported significantly lower cognitive load than printed images (mean = 7.5, SD = 4.9, p < 0.005). Instructional efficiency (E) of holograms (E = 0.35) was significantly higher than printed images (E = −0.36, p < 0.001), although not significantly higher than 3‐DPDF (E = 0.03, p = 0.097). Conclusions Participants using holograms demonstrated significant knowledge improvement over printed images and monoscopic 3‐DPDF models, suggesting additional depth cues from holographic visualisation provide benefit in understanding spatial anatomy. Mental effort scores and instructional efficiency of holograms indicate holograms are a cognitively efficient instructional medium. These findings highlight the need for further study of novel 3‐D technologies and learning performance.
