TABLE 3.

Correlations between accuracy and peak alpha frequency (PAF) during the pre-test task period, baseline and maintenance time periods (as shown in Figure 1).

	Pre-Test Task Period PAF				Baseline PAF				Maintenance PAF

2-Sample Precise	0.05	–	0.02	–	0.08	–	−0.00	–	0.00	–	0.08	–

3-Sample Relative	−0.02	–	0.49	0.03 (0.00)	0.03	–	0.44	0.04 (0.01)	−0.05	–	0.37	0.09 (0.04)

Accuracy means by Trial-type are shown in Table 1. Pearson’s r correlation statistics are shown along with p-values indicating significance of difference from zero. All p column values of “–” indicate a multiple-comparison-corrected p > 0.25. Values shown in parenthesis indicate the value of p without correction for multiple comparisons. Neither Males nor Females show a pattern of PAF correlating with Accuracy in Precise Task-type trials. For Males, there is indication of a positive correlation between PAF and Accuracy in Relative trials. A significant difference between Male and Female correlations—indicated in bold—is present for the 3-Sample Relative Task-type during the Pre-Test Task Period (z = 2.56, p = 0.01).
