All differences between l parameters in the three reward magnitudes in cognitive effort conditions were highly significant ( p < .001 in all cases).
All differences between l parameters in the three reward magnitudes in cognitive effort conditions were highly significant ( p < .001 in all cases).
Parameter s differed significantly between PLN 80 and PLN 400 ( Z = 2.606; p = .009; r = .18), and between PLN 80 and PLN 3000 ( Z = 3.173; p = .002; r = .22) reward magnitude conditions; however, the difference between the PLN 3000 and PLN 400 conditions did not reach statistical significance ( p = .140).
