Fill syringes with SignaGel

Double adhesive collars

Cable wraps

External electrodes

Use the correct form depending on whether they want SONA/monetary compensation (and sign consent form as well)

Put the completed questionnaire in the “completed” folder file

Be sure the electrode collars are not covering the active part of the electrode

If the participant requires glasses, have them wear them during cap fitting

Visually inspect the cap to ensure it is on straight

Anterior/posterior - Measure nasion to inion (divide by 2)

Left/right - measure from left to right preauricular area (divide by 2)

Double check that the cap is still straight now that you’ve made your adjustments

Build columns of gel: fill from syringe, move hair around

If participant is bald or has very short hair, start with minimal gel to avoid pooling

Check all 64 channels and also EX 1-6

Electrodes should be should be ideally between +/- 20 mV, not bouncing up and down

Look for channels that are drifting or seem particularly noisy

Use same techniques above to correct bad channels

Return to Electrode Offset tab and ensure all electrodes are still in range

Use this opportunity to emphasize why being relaxed, comfortable, and still is so important and why they should try to avoid blinking outside of the specified “blink times”

Turn ON by pressing talk button

Turn on Monitor Mode on the VERONICA intercom by pressing the Monitor button until you hear a tone

Do the same whenever you’re transitioning from between bright and dim tasks (e.g., from a paradigm that uses the anaglyph glasses to one that does not)

Turn off the WiFi

Pause Dropbox

Close all unnecessary programs

Press Start File

Press OK on popup window

Enter filename

At this point the file has been created, but it is NOT recording

Be sure to enter the participant’s “p” number as it is saved in the EEG file

Most of our experiments will automatically trigger the ActiView system to being recording. When PsychoPy begins the experiment you should confirm in the ActiView window that the button above the Pause button has turned from red to green and displays SAVING

Note: If you are running an experiment that does not automatically trigger EEG recording (unlikely), you would press the Pause button to begin recording

Most of our experiments will automatically pause EEG data recording when the experiment is over. However, you still need to terminate the session (i.e., close the file)

Press the Stop button

Remember to email this picture and a screenshot of their EEG to the participant

Turn on the WiFi

Unpause Dropbox

Tell them the goal of the studies that were run and give them the opportunity to ask any questions that they have

Enter your handwritten run sheet and notes into the Excel file

Keep the run sheet in the lab folder

Save the Excel file

Unmount the KPNL_Participant_Info.dmg virtual drive

Take extreme care to not stress the electrode leads

Electrodes should never come into contact with any metal surfaces (e.g., the sink!)

Follow the same procedures as used for the cap electrodes (see below)

Swirl electrodes in a half bucket of cold water

After ~45 sec feel for slipperiness to indicate if gel has been washed off

Change the water intermittently and continue until electrodes no longer feel slippery

Hang ribbons from the rack and spread out the electrodes to dry on the “wee-wee pad”

Use the sprayer to wash the gel out of each of the electrode holders

Wash in warm soapy (use a small amount of Ivory liquid soap) water in bucket

Wash so there is not gel in the fabric

Once clean, rinse the cap in clean water

Place the clean cap on one of the plastic cap racks to dry

If another participant is scheduled for the same day it is important to speed up drying of the cap. To do so,
