The neurobehavioral correlates of exploration without learning: Trading off value for explicit, prospective, and variable information gains
Summary: Exploration is typically motivated by gaining information, with previous research showing that potential information gains drive a “directed” type of exploration.

| description | Summary: Exploration is typically motivated by gaining information, with previous research showing that potential information gains drive a “directed” type of exploration. Yet, this research usually studies exploration in the context of learning paradigms and does not directly manipulate multiple levels of information gain. Here, we present a task that isolates learning from decision-making and controls the magnitude of prospective information gains. As predicted, participants explore more with larger future information gains. Both value gains and information gains, at a trial-by-trial level, engage the ventromedial prefrontal cortex (vmPFC), the ventral striatum (VStr), the amygdala, the dorsal anterior cingulate cortex (dACC), and the anterior insula (aINS). Moreover, individual sensitivities to value gains and information gains modulate the vmPFC, dACC, and aINS, but the amygdala and VStr are modulated only by individual sensitivities to information gains. Overall, we identify the neural circuitry of information-based exploration and its relationship with inter-individual exploration biases. |
