EEG study

This is what I looked like when I had the cap on, and all of the electrodes were attached to the cap as well as on my face and earlobes

A few days ago I participated in an EEG study, which looked at the "multiple-identity tracking: attentional bias mediated by gaze direction." The current experiment aimed to investigate at what stage of visual processing attentional bias occurs. To do so, the experimenter (who is actually my flatmate; a 4th year psychology student) measured my brain activity associated with different stimuli while I performed a multiple-identity tracking task. Basically, the experiment involved my completion of computerised tasks involving attending and responding to moving objects. The experiment was roughly 2.5 hours long.
For those wondering why I even took part in an EEG study is because it is part of my degree here at the uni to participate in psychology experiments (run by other students) to earn my credits. Moreover, EEG studies have always appealed to me and I have wanted to participate in one for quite a while. So when I got the chance I took it!

When the EEG cap was on my head and all of the electrodes placed in the correct areas, it was time for me to step into a soundproof booth.
In the booth, I was hooked up to the EEG machine which tracked my brain waves, which were presented on a screen in front of me.
For me to be able to see my brain waves on the computer, I was first asked to blink, which produced a big wave on the monitor. I was then asked to clench my teeth, which resulted in lots of small waves closer to each other, because of the pressure.

I have now been part of an EEG experiment which was an amazing experience that I would highly recommend to anyone.
My next accomplishment is to participate in a fMRI study and get a picture of my brain!!
