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.
