3.2 Reliability
The second research aim of this study was to determine if a simple procedure could produce reliable measures of amplitude and latency. To address this question, a Pearson’s r correlation coefficient was completed for split-half reliability comparing the mean amplitude of the even numbered trials to mean amplitude of the odd numbered trials separately for Block One (trials 1 – 240) and Block Two (trials 241 – 480). Reliability was further assessed by conducting Pearson’s correlation analyses to examine the test-retest reliability for mean amplitudes between the two blocks for the STP approach compared to the STW approach. A Pearson’s correlation was also conducted to examine test-retest reliability for latencies in the STP approach. Analyses for reliability are shown in the next two sections.
