Abstract
This article grows out of a workshop conducted at the XVI International Congress on PCP, Columbus, Ohio, in July 2005. Its intention is to show how qualitative repertory grids (CitationProcter, 2002) are useful in mapping construing in a family. Three types of grid are illustrated: the Perceiver Element Grid, the Event Perceiver Grid, and the Perceiver Construct Grid. Byron's play, “Cain: A Mystery” (Citation1821), is used as a case example.
