AbstractWhile monitoring evidence, a decision maker’s confidence for each hypothesis changes across time. What are the fundamental dynamics that underlie these changes in confidence during evidence accumulation? There are two fundamentally different ways to understand the dynamics of confidence. The “classical” way is to assume that the dynamics follow a Markov process, such as drift diffusion model (Pleskac & Busemeyer, 2010).A very different way is to assume that the dynamics follow a quantum type of process (Busemeyer et al., 2006). The current paper presents another new test of the Markov versus quantum models for the dynamics of confidence.
