if the age of the participants in the active task differed from those in the passive task a one-way ANOVA that compared the two groups was conducted. The second question focused on whether periadolescent active task participants differed from adult participants on energy, PDLI and PLI values. Three Multivariate Analysis of Variances (MANOVAs) were used to test between subject age effects for energy, PLI, PDLI separately for the rats and the human participants. Variables entered into the MANOVAs included: (1) group (periadolescent vs. adult), (2) electrode location (FZ, CZ, PZ) for energy and PLI and FZ-PZ for PDLI, (3) tone (frequent and infrequent tones) and (4) the 4 time frequency regions of interest (ROIs) (delta, theta, alpha, beta). If significant main effects were found, repeated measures and interactions were explored using post hoc ANOVAs. To determine if the number of behavioral responses of the adults and periadolescent participants in the active task differed, a one-way ANOVA that compared the two groups was conducted. To reduce type 1 error, significance was set at p<0.01.
