Risk-Sensitive Optimal Feedback Control Accounts for Sensorimotor Behavior under Uncertainty
Figure 8
Contribution of control cost to total cost, and extra cost from risk sensitivity.
A. Contribution of control cost to total cost for the high noise condition plotted against the low noise condition for the low control cost conditions (ellipses show 1 s.e.m. across all 250 trials). B. as A. but for the high cost level. C. Estimated extra cost in percent of a risk-sensitive controller with incomplete observation and sensorimotor delay based on the experimentally inferred -parameters for the low cost level. D. as C. but for the high cost level. E. Relationship between extra cost of a risk-sensitive controller relative to a risk-neutral controller for a range of
-values overlaid with the subjects' experimentally inferred
-parameters
standard deviation for the low cost level. F. as E. but for the high cost level.
