Can Monkeys Choose Optimally When Faced with Noisy Stimuli and Unequal Rewards?
Figure 7
Contours (black curves) of expected rewards for
for monkeys A (A) and T (B) over the (
)-plane, based on the coherences viewed by each animal.
Vertical dashed lines indicate values fitted to pooled equal rewards data. Note that gradients in
in either direction away from ridges of maximum expected rewards (blue curves) become smaller as
decreases, that gradients are smaller for overshifts in
than for undershifts, that this asymmetry increases as
decreases, and that gradients are steeper for T than for A. See text for discussion.
