Impaired Reinforcement Learning Underlying Explore-Exploit Decision Making in Theft Recidivists

This study finds that non-kleptomanic theft recidivists show impaired reinforcement learning, as evidenced by lower learning rates and reduced optimal choices in a 4-arm bandit task.

Altered Social Cognition Associated with Kleptomanic and Instrumental Thefts

This study examines social cognition differences between theft recidivists with and without kleptomania compared to controls using behavioral games and questionnaires.

Behavioral Economic Profiles in Theft Recidivists with and without Kleptomania

The paper compares behavioral economic profiles of theft recidivists with and without kleptomania, finding heightened loss aversion and price sensitivity in those with kleptomania.

Higher Impulsivity in the Heterogeneous Structure of Theft Recidivists with and without Kleptomania

This study compares impulsivity and brain activity in theft recidivists with and without kleptomania to control subjects, finding higher impulsivity and altered prefrontal cortex responses in theft recidivists.
