Grand Averages of the alpha band time courses for relaxed and engaged conditions indoors and in the car. For the red and the green curve, displaying the relaxed conditions, a similar pattern starting 1 s after onset of stimulus presentation is observed. Similarities over time are also apparent for the engaged conditions, represented in the black and blue curve. Clear co-variation of indoor and in car alpha time courses for both relaxed and engaged conditions is proven by high correlation between the signals.
