3.3. Validity of STP Approach to Single Trial Measurement
The third research aim was to determine if a simple procedure for measuring ERP peaks could be shown to be a valid approach. To evaluate validity of the STP approach, standard error of measurement (SEMs) for the STP approach were compared to the SEMs of the STW approach. Regressions were then used to determine if the single trial amplitude and latency measurement would significantly predict the averaged ERP amplitudes. These results are shown in the next two sections.
