Paper Abstract

Verbal protocol analysis has been widely used to capture the processes of problem solving behavior. Early research studied humans solving well-defined problems such as cryptarithmetic and Tower of Hanoi problems, but it also extended to chess. Other research has focused on continuous and discrete process control tasks. Our work explores some of the cognitive difficulties involved in CAD model construction. It addresses mental transformations in the physical world, and the nature of cognitive loads when constructing physical models. It also investigates the transport of skills from physical world model construction to a screen world construction process. This paper describes our findings and performance measures in the construction of physical models.
