Surprise beyond prediction error
Surprise drives learning. Various neural "prediction error" signals are believed to underpin surprise-based reinforcement learning. Here, we report a surprise signal that reflects reinforcement learning but is neither un/signed reward prediction error (RPE) nor un/signed state prediction error (SPE). To exclude these alternatives, we measured surprise responses in the absence of RPE and account...
متن کاملMaternal mortality: surprise, hope, and urgent action.
The apparent failure to reduce maternal mortality during 20 years of the Safe Motherhood movement has been one of the most deforming scars on the body of global health. Despite strong advocacy eff orts, political leaders have either ignored the call or failed to make the health of women in pregnancy their priority. This striking lack of progress, despite maternal mortality reduction being award...
متن کاملUpdating dopamine reward signals
Recent work has advanced our knowledge of phasic dopamine reward prediction error signals. The error signal is bidirectional, reflects well the higher order prediction error described by temporal difference learning models, is compatible with model-free and model-based reinforcement learning, reports the subjective rather than physical reward value during temporal discounting and reflects subje...
متن کاملBehavioral dopamine signals.
Lesioning and psychopharmacological studies suggest a wide range of behavioral functions for ascending midbrain dopaminergic systems. However, electrophysiological and neurochemical studies during specific behavioral tasks demonstrate a more restricted spectrum of dopamine-mediated changes. Substantial increases in dopamine-mediated activity, as measured by electrophysiology or voltammetry, are...
