This is the program we use for recording participant data as well as coding psychophysiology data. This program has multiple functions, and each should be paid attention to carefully because of the resources needed to collect psychophysiology data from a single participant.
For setting up any experimental recording for a study, the template needs to be configured first. The template should turn on the specific channels required for recording in a study (e.g., PPG, GSR, ECG, IMP, etc.). Also, the template should be preset for recording times, and be set to a “record once” recording format to begin. The channels shouldn’t be touched for each template as well, given the BIOPAC MP150 should already be configured with these machines.
- Once the template is set, ensure that all researchers know that the “record once” function is used so that they can calibrate the signals – ensuring they are coming in clearly and appropriately before starting full experimental recordings;
- During the course of the experiments, RAs will need to closely monitor signals, given electrodes can lose signals from coming loose, or participant movement (e.g., a participant crossing their legs or even posturing-up can alter signals drastically and can confound data);
- During the course of the experiments, RAs should be instructed clearly if they need to change recording times to append; Append = the next time the “record” button is pressed, the data will be recorded on the “back-end” of the already recorded data; Record Once = the next time the “record” button is pressed, the data will overwrite whatever was already recorded. It is essential to make sure data is not recorded over!
- Once data is fully recorded, is VERY important to ensure the data is labelled correctly and placed in the right folder. This will allow sorting by the lab manager to go by much quicker, than if files are wrongly named. Also, the files should be kept in a “raw” and “un-scored’ folder separately, for quick access to raw data files as well as time stamps for data collection.
Here is a link for the psychophysiology coding generally done in the lab given by Liz (note: this is a privatized link and should only be shared with the appropriate members of the lab):
