eLife Assessment
This study makes the important claims that people track, specifically, the elasticity of control (rather than the more general parameter of controllability) and that control elasticity is specifically impaired in certain types of psychopathology. These claims will have implications for the fields of computational psychiatry and computational cognitive neuroscience. However the evidence for the claim that people infer control elasticity is incomplete, given that it is not clear that the task allows the elasticity construct to be distinguished from more general learning processes, the chosen models aren't well justified, and it is unclear that the findings generalize to tasks that aren't biased to find overestimates of elasticity. Moreover, the claim about psychopathology relies on an invalid interpretation of CCA; a more straightforward analysis of the correlation between the model parameters and the psychopathology measures would provide stronger evidence.
