The aim of the study is to investigate whether a voice activated cognitive aid can improve performance in a simulated emergency front-of-neck access scenario. This skill is ideally practiced on an annual basis by anaesthetists in training, with a variety of usually low-fidelity simulation used.
The addition of the Alexa cognitive aid is a novel step with the aim of improving adherence to the recommended steps required to successfully complete the procedure. One arm of this study will be introduced to the Alexa checklist in advance of performing the procedure prior to crossover, whereas the second arm will not (subject to standard anaesthetic training).

Randomisation will be carried out using a randomization table made at www.randomizer.org to even/odd allocation numbers corresponding to 'Alexa first' vs 'No Alexa first' group with equal allocation between each arm. The randomisation sequence will be known only to the investigators issuing the initial grouping to the candidate, and allocations will be concealed from the video recording assessors and the statistical analysis team.

Assessors marking the recorded performances will be blinded as to which group the candidate had been allocated to in the first instance. The statistical analysis team will also be blinded to the allocation sequence.
| 6 months |
| A measure of participant workload (e.g. NASA-TLX) as perceived and completed by the participant after each arm. | Workload time versus perceived time per participant | 6 months |
| A measure of team working (e.g. ANTS score) for each individual procedure | Actual measure per participant per procedure | 6 months |
| A measure of participant's subjective experience (e.g. qualitative analysis of participant feedback on the device) | Feedback from each participant about the device | 6 months |
