Abstract
This study presents the results from the analyses of verbal protocols elicited from inexperienced and experienced participants of a real-time, Dynamic Decision-Making (DDM) task. This research intends to complement a series of studies performed in DDM environments analyzing the cognitive structures and processes involved in learning in DDM. Results show that inexperienced and experienced participants differ in several ways: in the way they distribute attention to different parts of the system, in their awareness of the relationship of the attributes involved in the decision making process, and in their coordination to make decisions in real time. These results have been used to support the refinement of a cognitive model developed to explain how people learn in DDM tasks.
Highlights
Real-time, Dynamic Decision Making (DDM) has three main characteristics: a) multiple and interdependent decisions; b) the environment changes because of exogenous events and because of prior decisions; and c) the pacing of decisions is dictated by the task rather than by the decision maker (Brehmer, 1990)
Our research investigates learning in dynamic decision making situations and we have developed cognitive models of the learning process (Gonzalez, Lerch, & Lebiere, 2003)
This paper reports a study on the collection and analysis of verbal protocols from individuals with different experience in a Dynamic Decision-Making (DDM) task
Summary
Real-time, Dynamic Decision Making (DDM) has three main characteristics: a) multiple and interdependent decisions; b) the environment changes because of exogenous events and because of prior decisions; and c) the pacing of decisions is dictated by the task rather than by the decision maker (Brehmer, 1990). Verbalizations of the thought process are often used to study expertise and decision making in real-world complex tasks (Hoffman, Shadbolt, Burton, & Klein, 1995). These methodologies are frequently used as the basis to build cognitive models. This paper reports a study on the collection and analysis of verbal protocols from individuals with different experience in a DDM task. These protocols can inform modelers of the search, judgment and choice strategies development with experience
