Table 2.

The correlations of the entropy measures and the other measures of AGL performance for the Reber and Allen (1978) training, test stimulus sets and for the Knowlton and Squire (1996, Exp. 1) training, test stimulus sets.

Note: Each cell of the table shows the correlation between an entropy measure and a standard AGL measure for the Reber and Allen grammar (first number) and the corresponding correlation for the Knowlton and Squire grammar (second number). Correlations which are significant at the 0.05 level are flagged with an ‘*’ and correlations which are significant at the 0.01 level are flagged with an ‘**’.
