Hi all,

Shortly we will be running a pretty cool EEG experiment on perceptual decision making in romantically involved couples. Basically, a couple (let’s call them Alice and Bob) will come into the lab, each be assigned their own computer and then take turns in a perceptual decision making task (see Jolij and Meurs, 2011, for more details on the task itself). So, first Alice will get to see a trial and give a response; then Bob will see Alice her response (as a cue) and will do the trial, and to conclude, both will see each other’s answers. During the experiment, we’ll be measuring EEG (NB: only 8 channels). Before the experiment, both partners fill out a series of questionnaires on relationship duration, quality, etc.

In the spirit of open science, I though it might be useful to ask you all what would make this dataset useful for you. I mean, we are going to test these participants anyway, in a rather non-typical setup (two EEG measurements simultaneously, meaning you can look at all kinds of interpersonal processes, EEG synchronization, ect.), so if there is anything I could add that does not take too much time so this could be an interesting dataset for you, let me know. Think of maybe a block of eyes-closed EEG data during a breathing exercise to study interpersonal synchrony, a particular questionnaire, additional markers, whatever.

As long as it does not add too much time to the experimental protocol, or takes up too much time programming, I am happy to include stuff. Please do get in touch if you want to know more: j.jolij@rug.nl.
