Methods for Conducting Cognitive Task Analysis for a Decision Making Task

摘要

Cognitive task analysis (CTA) improves traditional task analysis procedures byanalyzing the thought processes of performers while they complete a task. For this report, we have selected several of the measures for which we found differences in experts and novices and have detailed the procedures for using these methods to conduct a CTA for domains which involve critical decision making tasks in naturalistic settings. The cognitive task analysis methods that we describe are: (1) development of a task process model, (2) development of an information flow model, (3) misconceptions analysis, and (4) structural knowledge analysis. For each of these methods we describe how information is gathered (knowledge elicitation), how it is represented in a format that can be later used in designing training (knowledge representation), and how the knowledge can be used in developing training.
