Upon arriving to the lab, infants were fitted with a lycra stretch cap (Electro-Cap International, Inc., Eaton, OH) with electrodes in the 10/20 system pattern (Jasper, 1958). Once the cap was secured on the child’s head, a small amount of abrasive gel was placed into each recording site and gently rubbed into the scalp; conductive gel then was placed in each site. Electrode impedances were measured and accepted if they were below 10 kW.
