the researcher's and the participant's safety should both be taken into consideration
researchers should always wear a mask while conducting studies
protocols will be explained to shorten the exposure between researchers and participants

Paperwork to have ready:

Important Supplies:

Measuring tape
Grease pencil
Hair clips
2 full, pre-filled syringes and extra gel
an extra syringe needle
Wooden dowels
Paper towels
Electrode sticky discs
Electrodes VEOL, VEOU, HEOL, HEOR, and nose reference (long wire)
- Missing or broken electrodes can be substituted with another of a different label as long as it is applied and connected in the proper location

After the participant has signed the informed consent sheet, have the participant brush through their hair with a disposable comb and clean off their face with a towelette (specifically on their nose and around their eyes, as electrodes will be placed there)
Using the tape measure, have the participant hold the start of it against their nasion and go over the top of their head until you reach the inion, and write the total number down in cm (this measurement will tell you if they require a S, M, or L cap)

Take 10% of that number, then measure that distance on the participant's forehead and mark it with a grease pen. This will be used as a reference for where the front of the cap should be placed.
Guide the participant into the EEG study room and check the EEG cap log to make sure to use the least recently used cap in that size.
With the proper cap, have the participant sit still, align the front of the cap with the grease mark using your thumbs along the front edge to hold it in place,
