Table 3.

Correlation coefficient between 4-s data and 10-s data for each of the proposed measures. Correlations with p-values between .01 and .05 are given in italics and correlation with p-values that are less than .01 are given in bold. Number of bouts is denoted by n, spike size is denoted by π, and average slab size is denoted by μ and is expressed in number of 4-s epochs.
