Stimulus uncertainty and relative reward rates determine adaptive responding in perceptual decision-making
Fig 5
Trial-by-trial fits of the IR, IRO and IR&RO models to the experimental data.
a. The fraction of leftward responses in each session, P(R2), is plotted for each individual animal across the different experimental conditions, similar as in Fig 3C. Orange lines are model fits. Blue lines are averages over 1000 simulations; blue shaded areas represent ±1 SD. b. Distributions of fitted parameters of the different models. Each data point pertains an individual subject. c. Regression weights for rewards and reward omissions. The regression weights indicate the influence of both types of outcomes (blue for rewards and red for reward omissions) for trials t-1, t-2, t-3 and t-4. Dashed lines represent individual rats and thick lines means across the four subjects. See Methods for details of the GLM fit.
