Abstract

Extrapolation of theories of cognitive modelling from psychological contexts to the domains of information systems design has raised empirical questions regarding the validity and reliability of these techniques in the new applications environment. Kelly's theory of personal construct psychology (PCP) is one such theory which, together with the repertory grid technique of cognitive modelling, is being explored for use in systems development. Provides a test of the repertory grid for representing commonality of construing among members of a homogeneous group of subjects. Commonality of construing is demonstrated on 2 sets of constructs. Some differences are observed between constructs generated by the subjects and those provided for them by an 'expert'. Describes the implications of this effect for the application of PCP to intelligent front end interfaces for information retrieval systems
