INTERPRETING INVENTION AS A COGNITIVE PROCESS - THE CASE OF BELL,ALEXANDER,GRAHAM, EDISON,THOMAS, AND THE TELEPHONE

Historians of technology have provided important accounts of technological innovation,but they rarely employ concepts whichpermit a rigorous analysis ofinvention as a mental or cognitive process. This article seeks to address this theoretical lacuna by using concepts adapted from cognitive psychology to compare the mental processes of two telephone inventors, Alexander Graham Bell and Thomas Edison. Specifically, we suggest that invention may be seen as a process in which inventors combine ideas with objects, or what we call mental models and mechanical representations. The strategies by which inventors generate and manipulate these mental models and mechanical representations are what we refer to as heuristics. Using these concepts to narrate the development of the telephone, this article shows how invention can be interpreted as being much more than simply a mysterious act of individual genius. © 1990, Sage Publications.
