Table 1. Parameters and coefficient of determination for the best fits of Eqs. 3 and 5 to the data of effort-sensitive monkeys.

Monkey kw kd E0 R2
CS 5.9 4.2 0.2 0.98
FG 6.8 3.6 4.1 0.99
KN 22.2 7.8 7.3 0.95
TT 5.9 2.5 3.7 0.94
Average 10.2±8.0 4.5±2.3 3.8±2.9 0.97±0.02

The fits corresponding to these parameters are plotted in Figure 2A. Average reports mean ± SD. There is significant difference between kw and kd (p<0.05, paired t-test with logarithmic transformation).
