  1. denotes the successive addition of variable blocks to the hierarchical regression, as defined in the Methods
  2. a significant value in this column it indicates that the additional block of variables adds significantly (in terms of variance) to the prediction of the outcome variable. * p < .05, ** p < .01, *** p < .001
  3. § using the Bonferroni correction for multiple comparisons, p = < 0.01 for significance
  4. VR = Verbal Reasoning, QR = Quantitative Reasoning, AR = Abstract Reasoning, DA = Decision Analysis
