Task Analysis through Cognitive Archeology. Frank Spillers1 Experience Dynamics 1Experience Dynamics, 809 NE Imperial Avenue Portland, Oregon 97232. Email : frank@ Analysis and observation of the user’s task domain unveils a window of understanding into the behavioural patterns, contexts and scenarios that are required and utilized by users to attain success in completing a task. Task Analysis (TA) forms the foundation for interaction, behavior and usage since prioritisation of design elements is a serious issue for both users and designers. Successful User Interface (UI) designs often utilise insight into tasks by studying user interactions, intentions, and expectations. User interaction itself amounts to the interplay of cognition and information processing as embodied by task routines or sequences that are commonly captured in a TA. This chapter will focus on procedures for uncovering cognitive processes relative to user goals and tasks including decision-making systems, the impact of information overload on screen display, and the significance of user roles to tasks. The notion of a “cognitive archeology” as a means to investigating task cognition will be explored and explained as a novel best practice in TA. “Cognitive archeology” or the capture of cognitive processes required and utilized by users for task completion offers a necessary insight into the interchange of co
