A cognitive
approach of the analysis of design processes, in Design Theory and
Methodology -- DTM '90 --, pp. 153–160, The American Society of
Mechanical Engineers (ASME) (1990).
The scientific analysis of design is indispensable in order to
establish a rich and useful design theory. Accomplishing this, we propose a
practical method to investigate design named design experiment and methods to
analyze its results. Since the design experiment is performed mainly with the
protocol analysis method, We start from discussing the experimental method in
comparison to psychological experiments. Furthermore we introduce a new
method using a CAD-like system which can record drawing processes precisely.
We analyze the protocol data in two ways. One is the analysis by extraction
of knowledge. Using this we can clarify how knowledge is uded and what
knowledge is needed in design process. The other is based on the cognitive
approach. Protocol data is transformed into the semantic network of concepts
which is used as the network in the connectionist paradigm. We can identify
what the designer pays attention to and how it is changing in design
processes by regarding the activations of nodes as the intensity of the
designer's attention.
