The timing of exploratory decision-making revealed by single-trial topographic EEG analyses

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Nicolas Bourdaud, Micah Murray, Athina Tzovara

Decision-making in an uncertain environment is driven by two major needs: exploring the environment to gather information or exploiting acquired knowledge to maximize reward. The neural processes underlying exploratory decision-making have been mainly stud ...

Control of Attention to Mental States and Multiple Critics

Arash Arami

Attentional modulation is needed when a decision maker is faced with too much information to process. In this paper we discuss the use of attention in control applications where usually higher order system dynamics are involved as typical benchmarks consid ...
