As a second approach to interpreting the condition by age group interactions for ITC we conducted trend analyses (200-400 ms by 4.5 Hz to 8 H and 350-450 ms in the 4-5 Hz ranges). These ranges consistently reflected a quadratic pattern for no win theta trial to trial phase synchrony (ITC), which was reduced in the 10-12-year-old group, increased in the13-14-year-old group and then decreased again for the 15-17-year-old group. Future work will need to link developmental patterns of theta oscillation to learning (Cavanagh et al. 2010), decision making (Cohen et al., 2009) and risk behavior inside and outside the laboratory (Lejuez, Aklin, Zvolensky, & Pedulla, 2003).
