**Correlation is significant at the 0.01 level (2-tailed). *Correlation is significant at the 0.05 level (2-tailed).
^athe test of the difference between two independent correlation coefficients is significant (p < .05).
The differences between correlation coefficients are calculated with Preacher, K. J. (2002, May). Calculation for the test of the difference between two independent correlation coefficients [Computer software]. Available from http://quantpsy.org
