Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Within the time and resource constraints of postgraduate medical training, it would be advantageous to optimise expertise acquisition of practical skills with a cheap, self-directed educational intervention. Therefore, the aim of this study is to determine whether gaze training is associated with improved performance of an ultrasound-guided needle task. The investigators hypothesise that improved gaze control will translate to better technical performance of an ultrasound-guided regional anaesthesia task.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group Gaze
The gaze-trained group will be shown a video, derived from the eye tracker, of an expert's visual control whilst performing the ultrasound task. Participants will be made aware of the target-focused gaze strategy (lengthy and stable fixations on the needling target), and the manner in which the gaze shifted from target to tools (hands, needle and transducer) in a fast, smooth fashion. They will then be advised to try to mimic the gaze strategy of the expert while undertaking the needling task as their first training task. After completion of this training task, participants will be shown their own video data, as captured by the eye tracker. Participants will be asked to comment on differences between their own video and the expert video they had previously seen. This feedback process will be replicated a further four training task attempts. Participants in this group will therefore undergo a total of five training attempts of the needling task.

Group Discovery
The discovery learning group will be given no video feedback and will be instructed to perform five training attempts at the needling task without further training or feedback.
Discovery learning
A phase of discovery learning guided by novice operators themselves
