Some practitioners conduct a Cognitive Task Analysis (CTA) as part of the instructional analysis or as a separate analysis. These processes include the knowledge, skills and strategies . Task analysis is used to identify, analyze and systematically document the actions taken and the inputs used to accomplish results at this time. Broadly speaking, CTA can be used to better understand the macrocognition in . Cognitive task analysis (CTA), an analysis of the knowledge, thought processes, and goal structures of cognitive tasks (Hollnagel 2003), has been used to design new system interfaces, in cognitive engineering of hu-man-machine systems, to develop expert systems, for operator selection, and for training purposes (Wei and Salvendy 2004). Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. c. It expands a task analysis to incorporate differences in diversity. 2.1 Follow the unique steps for backward chaining. A. Cognitive Task Analysis.

Cognitive task analysis (CTA) has evolved over the past half century to capture the mental decisions and analysis that experts have learned to implement when solving complex problems. The cognitive test can be conducted in the time of approximately one week and requires only a few interviewers. The Knowledge Audit as a Method for Cognitive Task Analysis . The following steps outline the procedures to conduct the cognitive test of the Washington Group questions: The easiest way to illustrate the process is with an example. These methods aim to enable researchers to understand how workers make judgements, plans and decisions, interpret situations and use cognitive skills to perform work tasks. Cognitive task analysis is an in-depth task analysis that is usually performed by psychologists that made themselves familiar with the task to the extent of a trainee.
