Action observation for sensorimotor learning in surgery

Abstract

Background Acquiring new motor skills to learn complex movements and master the use of a diverse range of instruments is fundamental for developing expertise in surgery. Although aspects of skill development occur through trial and error, watching the performance of another individual (action observation) is an increasingly important adjunct for the acquisition of these complex skills before performing a procedure. The aim of this review was to examine the evidence in support of the use of action observation in surgery. Methods A narrative review of observational learning for surgical motor skills was undertaken. Searches of PubMed and PsycINFO databases were performed using the terms ‘observational learning’ OR ‘action observation’ AND ‘motor learning’ OR ‘skill learning’. Results Factors such as the structure of physical practice, the skill level of the demonstrator and the use of feedback were all found to be important moderators of the effectiveness of observational learning. In particular, observation of both expert and novice performance, cueing attention to key features of the task, and watching the eye movements of expert surgeons were all found to enhance the effectiveness of observation. It was unclear, however, whether repeated observations were beneficial for skill learning. The evidence suggests that these methods can be employed to enhance surgical training curricula. Conclusion Observational learning is an effective method for learning surgical skills. An improved understanding of observational learning may further inform the refinement and use of these methods in contemporary surgical training curricula.

Training Skills in Minimally Invasive, Robotic and Open Surgery: Brain Activation as an Opportunity for Learning

“…Before and after training, we also documented variable cortical activation in the different groups, both during the observation and execution of tasks. These data confirm that observing the actions of others is a cornerstone for the development of expertise and skilled behavior [16], and they support observational learning as an effective method for acquiring surgical skills [17]. Improved understanding of observational learning may further refine methods of surgical training.…”

The application of the spot the difference teaching method in clinical skills training for residents

“…Observation and imitation are two crucial characteristics in medical skill education [ 18 ], and they have a variable influence on learning through format, content, and programming. The SDTM is derived from the terms and rules of the popular game called "spot the difference," which is a type of observational learning.…”

What do faculties specializing in brain and neural sciences think about, and how do they approach, brain-friendly teaching-learning in Iran?

“…Furthermore, role modeling activities were stated as an important mentorship process in this study, since learners often learn by observing and imitating a role model. Evidence revealed that learning by observing and imitating others can be facilitated by mirror neuron`s activities in social contexts (55). Ramani (2003Ramani ( , 2008 and Carter (2016) explained that a clinical medical educator has the opportunity to be a role model to his learners and teach professional ethics and professionalism, performing procedures and conducting physical examinations without lecturing in a purely theoretical mode (56)(57)(58).…”
