On Wednesday, December 6th, James Palestro became the first student in the MbCN lab to complete his masters thesis. James’ work focuses on a recent debate between fixed and collapsing boundary models, which argue either against or for a temporal component of decision making. He reports an experiment of speeded two-alternative forced choice decisions using a mixture of free response and interrogation paradigms to differentiate the qualitative and quantitative predictions of the two model classes. In the end, his results suggest that some task demands induce a collapsing bound strategy.
When choosing among menu items at a restaurant, ever wonder how you represent and choose among items? We recently published a paper investigating the mechanisms at work during the deliberation process among multi-attribute, multi-alternative choices. To do this, we used Bayesian statistics to fit the extent theories of how this process unfolds, as well as an analysis meant to investigate the plausibility of various model mechanisms by testing each possible configuration.
