Mean and total goodness of fit values are also provided for data modeling (RMEAN2 and RTOTAL2, respectively). Significant key parameters (difference from zero) are indicated by asterisks. Note that peak times and bandwidths are interpretable only when the peak amplitude is also significant.

a = baseline-corrected amplitude; x = peak time; b = bandwidth.

*p < .02.

**p < .01.

***p < .005.
