An experiment aiming to assess the use of stopping rules ininformation acquisition was performed. Participants wererequested to make a decision in 24 financial scenarios withthe possibility of buying information pieces. Behavioral andEEG data were recorded for analysis. Results showed thatparticipants followed Bayesian calculations in order todetermine a stop on information acquisition and decide.Moreover, the information acquisition strategies wereconsistent with prospect theory, in which participants willweigh information pieces differently and seek more or lessinformation given different manipulations in scenarioprobability and consequences. EEG data suggest SlowCortical Potentials at fronto-central electrodes.
