The failure of the second pair of investigators to replicate the first pair's work would seem to say more about the complexity of the procedure itself than about the conduct of the inquiry. One possible source of difficulty, though not necessarily the one which accounts for Hirsch and Leff's failure to replicate, is the status of the descriptive categories. As we mentioned, there are two major methodological problems with content analysis categories for schizophrenic speakers: (a) the categories are very weakly connected to the theoretical constructs, and (b) the categories are based on inferential procedures so that one does not know the extent to which different analyses are applied.
As we mentioned, there are two major methodological problems with content analysis categories for schizophrenic speakers: (a) the categories are very weakly connected to the theoretical constructs, and (b) the categories are based on inferential procedures so that one does not know the extent to which different analyses are applied. With regard to (a), there is some basis for believing Singer and Wynne's categories to be motivated independently by theory. Wynne (1977) reports that he and Singer "used a certain face validity" in selecting events that seemed to require the maintenance of a shared task set and a common focus of attention.
6. Summary of Content Analyses. The five sets of content analyses reviewed here offer an overview of the problem facing those who attempt to understand the schizophrenic speaker. They demonstrate a stubborn conundrum: analyses performed by human coders can produce remarkable discriminations, but the bases on which they operate are obscure, whereas analyses performed by computers are based on well-defined procedures, but the discriminations that they produce are rather weak. To exaggerate the situation a bit, it seems that when our measures are discriminating, we cannot tell what they are measuring; and when we can tell what they are measuring, they are not very discriminating.
