Robust versus optimal strategies for two-alternative forced choice tasks.
It has been proposed that animals and humans might choose a speed-accuracy tradeoff that maximizes reward rate. For this utility function the simple drift-diffusion model of two-alternative forced-choice tasks predicts a parameter-free optimal performance curve that relates normalized decision times to error rates under varying task conditions. However, behavioral data indicate that only ≈ 30% ...
متن کاملRobust satisfying versus optimizing strategies for two-alternative forced choice
The optimal strategy for two-alternative forced choice experiments results in a single optimal performance curve that relates the normalized reaction time to the error-rate. Comparison with experimental data indicates that the optimal performance curve describes well the performance of the top 30%-40% of the best performing subjects. Here we investigate the possibility that subjects exercise ro...
متن کاملA self-initiated two-alternative forced choice paradigm for head-fixed mice
Psychophysical tasks for non-human primates have been instrumental in studying circuits underlying perceptual decision-making. To obtain greater experimental flexibility, these tasks have subsequently been adapted for use in freely moving rodents. However, advances in functional imaging and genetic targeting of neuronal populations have made it critical to develop similar tasks for head-fixed m...

متن کاملAppendix A. Mathematical details of decision optimization in two-alternative forced choice tasks
In this appendix we collect and describe mathematical results for first passage, boundaryless, and reflecting-boundary drift diffusion problems. We consider both diffusion and OrnsteinUhlenbeck (O-U) models. The main tools are drawn from applied probability, the theory of stochastic ordinary differential equations, and classical perturbation and asymptotic methods. Here we focus on continuous m...
