Capturing decision confidence through response trajectories and willingness to gamble
Year: 2017
Type: conference-paper
Abstract: We aimed to investigate whether action dynamics could be employed as an objective measure of decision certainty and the relationship between certainty and confidence. Twenty-eight participants were required to view a random dot kinematogram display and report the dominant dot direction by moving the computer mouse. Directly following this, they were required to report the amount of points they were willing to bet that the answer they gave was the correct one. Coherence of the stimulus was experimentally manipulated and participants were required to complete 11 experimental blocks, each containing 48 trials of varying dot coherence. Mouse trajectory information was not predictive of post-decision certainty but was strongly related to decision accuracy. The findings were in line witha view of confidence as an evaluation of evidence which continues to accumulate after a decision.
