Abstract
Signal detection theory forms the basis of many current models of memory, choice, and categorization. However, little research has examined precisely how the decision-making process unfolds over time. In this paper, a new nonparametric, dynamic model is proposed with the intentions of ameliorating some long-standing issues in the signal detection framework and describing the changes in signal detection performance over time. The model uses a recursive kernel density estimation procedure that accumulates and stores experience across trials. I present the results of several simulations and show that the proposed model bypasses the rigid assumptions of prior internal representations of the sampling distributions and as a consequence, it allows the criterion location to shift to accommodate new information as it is presented.
