Extended Data Fig. 2: Parameter recovery and correlations for the reinforcement learning model with association specificity deficit.

(a) Correlations (linear regression) between estimated and original parameters. Note that most parameters were recovered with r > 0.7, with the least faithfully recovered parameter being the state transition observation rate η^tm with r < 0.6. (b) Correlations between fitted parameters (linear regression). Note that only correlations between \(\nabla _{{{{\mathrm{pell2cue}}}}}\) and w^mf (r=−0.54) in HB and between \(\nabla _{{{{\mathrm{pell2cue}}}}}\) and η^tm (r=−0.57) are substantial. CTRL n= 13 and hM4d n=15 fits of data from biologically independent animals.
