Beyond symbolic models

Using a biologically plausible model, we have been investigating some external and internal factors related to the stimulus representation that might affect the decision making and action selection [41] . We used a computational model of the cerebral structure Basal Ganglia, inspired and replicated from a model designed in previous studies [54] . One of the questions we attempt to address is to what extent the physical properties of the stimulus affect the decision to overcome the impact of reward associated to the stimuli.
