The Development of Distinct Choice Process Segments over Time: A Stochastic Modeling Approach
基于Howard的决策类型划分，通过纵向实验研究信息获取量，用随机模型在个体层面检验有限问题解决和常规化反应行为两个片段的存在。
This paper examines Howard's (1963) typology dividing decision making into extensive problem solving (ESP), limited problem solving (LSP), and routinized response behavior (RRB). Specifically, the amount of information accessed in a longitudinal experiment is studied. Information acquisition is modeled stochastically at the individual level, and the existence of two segments (LSP and RRB) is tested in a nested-model framework.
