Table 1 Intercorrelations and internal consistencies of all variables (Study 1)

From: Dispositional individual differences in cognitive effort investment: establishing the core construct

Variable 1 2 3 4 5 6
1 NFC .87      
2 Intellect .70 .96     
3 Seeka .71 .94 .93    
4 Conquera .61 .95 .78 .93   
5 Self-control .28 .31 .26 .33 .83  
6 Effortful control .34 .37 .35 .35 .74 .83
  1. Coefficients are Pearson correlations (all p < .001); values in the diagonal give the internal consistencies (Cronbach’s α)
  2. aCorrelations with seek and conquer are not part-whole-corrected, part-whole corrected correlations equal the bivariate correlation between seek and conquer
